Maternal Behavior

To test the hypothesis that selective breeding for high voluntary wheel running negatively affects maternal performance in house mice, we observed maternal behavior and compared litter size and mass, in replicate lines of selected (N =4) and control (N=4) mice from generations 20 and 21 of an artificial selection experiment. At generation 21, selected-line females ran 2.8-times more revolutions per day than females from random-bred control lines, when tested at approximately 6 weeks of age as part of the normal selection protocol. After giving birth, dams from selected and control lines exhibited similar frequencies of maternal behaviors and also spent similar amounts of time in general locomotor activity at litter ages of both 9 and 16 days. Dams from selected lines also performed equally well as controls in repeated pup-retrieval trials. At first parturition, selected-line dams averaged 2.4 g smaller in body mass as compared with dams from the control lines; however, neither litter size nor litter mass at birth (generation 20) or at weaning (generation 21) differed significantly between selected and control lines. We conclude that, at least under the husbandry conditions employed, maternal behavior and reproductive output at first parturition are genetically independent of wheel-running behavior.

for the Lifeways Cross-generation Cohort Study Steering Group BACKGROUND/OBJECTIVES: Animal models have demonstrated that maternal overnutrition during pregnancy influences offspring adiposity. Few human studies of normal pregnancy have replicated these findings. We examined the association between child body mass index at age 5 years and maternal nutrient intake during pregnancy and 5 years postpartum. SUBJECTS/METHODS: Five-year-old children (n ¼ 585) and their mothers were recruited during pregnancy from two maternity hospitals in Ireland. Data are from the Lifeways Cross-Generation Cohort study with detailed dietary information obtained during pregnancy and postpartum using a food frequency questionnaire. Nutrient intake was adjusted for energy intake (EI) and expressed in quartiles. Heights and weights were measured when the children were aged 5 years. We performed multivariate logistic regression analyses to examine the independent associations of macronutrients (protein, fat and carbohydrate) and their components (saturated fatty acid (SFA)/monounsaturated fatty acid/polyunsaturated fatty acid and sugar/starch) with child overweight/obesity. Associations were examined for nutrient intake during pregnancy (T1), at 5 years postpartum (T2) and the change in nutrient intake between T1 and T2. RESULTS: Total mean (s.d.) EI was significantly higher during pregnancy (2548 ± 1239 kcal) than 5 years postpartum (2084±718 kcal). Increased odds of overweight/obesity were found in mothers with higher intakes of sugar at T1 (Q4 odds ratio (OR): 4.57, 95% confidence interval (CI): 1.01-20.69) and high intakes of SFA at T2 (Q4 OR: 3.35, 95% CI: 0.97-11.57). Mothers with persistently high intakes of SFA and those who reduce their sugar intake between T1 and T2 were more likely to have overweight/ obese children. CONCLUSION: Maternal prenatal sugar and pre/postnatal SFA was associated with offspring adiposity.

Exposure of pregnant rats to stress results in offspring that exhibit abnormally fearful behavior and have elevated neuroendocrine responses to novelty and aversive stimuli. This study examined the effects of prenatal stress on plasma corticosterone, adrenal weight, defensive withdrawal behavior, and the density of receptors for corticotropin releasing factor (CRF) in the amygdala. Pregnant Sprague-Dawley rats were stressed by daily handling and saline injection (s.c., 0.9%, 0.1 mL) during the last week of gestation. Male offspring were studied at adulthood (60-120 days of age). Adrenal hypertrophy and increased plasma corticosterone were observed in the prenatally stressed offspring. Defensive withdrawal, an ethological measure of the conflict between exploratory behavior and retreat, was quantified in naive offspring, and in offspring exposed to restraint stress (2 h). Restraint stress increased defensive withdrawal in both control and prenatally stressed offspring. Both naive and restraint-stressed prenatally stressed offspring exhibited increased defensive withdrawal compared to control offspring. There was a significant interaction between prenatal stress and restraint stress, suggesting increased vulnerability of prenatally stressed offspring. The effects of restraint in the defensive withdrawal test were reduced by intracerebroventricular administration of the CRF antagonists, ␣-helical CRF9-41 (20 g every hour) or D-phe 12 , Nle 21,38 , C ␣-MeLeu 37 ]-CRF (12-41) (5 g every hour) during the restraint period. The difference between control and prenatally stressed offspring was abolished by the CRF antagonists, suggesting that increased activation of CRF receptors may be a factor in the behavioral abnormalities of prenatally stressed rats. Measurement of CRF receptors in amygdala revealed a 2.5-fold increase in binding in prenatally stressed offspring. In light of previous work from this laboratory demonstrating increased content and release of CRF in amygdala from prenatally stressed offspring, the present study suggests that the increased fearfulness of prenatally stressed rats may be a consequence of increased activity of CRFergic systems in the amygdala.

to explore women's perceptions of conflicting advice around breast feeding from formal support networks, specifically health professionals involved in postnatal support. a qualitative exploratory design was employed using the critical incident technique. Data were obtained from 62 Western Australian women who responded to an invitation to share incidents of receiving conflicting advice. Women who had breast fed a child within the past 12 months shared their experience through a telephone interview (n = 50) or completing a brief questionnaire (n = 12) addressing the following questions: Describe a situation in detail where you felt you received conflicting advice about breast feeding from a health professional. How did this situation affect you and/or your breast feeding? a modified constant comparison method was used to analyse the critical incidents revealing commonalities under who offered conflicting advice; what contributed to advice being perceived as conflicting; topic areas more inclined to being regarded as conflicting; what protected against advice being perceived as conflicting; the consequences of receiving conflicting advice; and strategies that women used to manage these incidents. advice that was viewed as conflicting extended beyond the provision of information that was inconsistent or directly contradictory, and included issues around information overload and disparities between the mother's and health professional's expectations. The manner of presenting information or advice, the skills of using effective communication, demonstration of a caring attitude with an empathic approach and focusing upon the woman as an individual were seen to be important to minimise these incidents. Attention to women's perceptions and the consequences of conflicting advice must be addressed, otherwise the credibility and confidence in health professionals' knowledge and ability to support breast feeding is questioned, resulting in a valuable support network being selectively ignored.

Background: Assessment of mothers in the year after childbirth is important for a number of reasons, including the well-being of the mother and healthy development of the child. There exists a body of instruments that measure a range of maternal characteristics, such as maternal confidence and self-efficacy. It remains unclear if any of these assessments can be used to measure maternal functioning, which may be a direct indication of potential hazards to the offspring. Accurate assessment of functioning would also aid in identifying women who are struggling in the maternal role. In order to assess whether commonly used maternal assessments extend into the realm of functioning, it is necessary to have an appropriate definition. Therefore, the aims of this analysis are to (1) present a new, patient-centered definition of maternal functional status and (2) evaluate select maternal assessments against this definition. Methods: Three new mother focus groups were held in order to understand women's experiences in the year after childbirth. These experiences informed the definition of maternal functional status, which was used to evaluate select instruments for their capacity to assess maternal functioning. Results: None of the instruments covered all seven domains, and all of the instruments covered at least one domain. Conclusions: Although there are means of assessing depression status in the postpartum, there is no comprehensive way of capturing a woman's quality of life. A new measure is required in order to capture this multifaceted, patient-defined construct of maternal functioning.

Abstract
Aim  To test whether alcohol is a risk factor for sudden infant death syndrome (SIDS).
Design and setting  US epidemiological study using computerized death certificates, linked birth and infant death dataset, and Fatality Analysis Reporting System.
Participants  All SIDS cases (n = 129,090) and other infant deaths (n = 295,151) from 1973–2006; all persons involved in late‐night alcohol‐related crashes (n = 135,946) from 1994–2008.
Measurements  Three measures were used: the expected number of deaths on New Year versus the observed number (expected values were determined using a locally weighted scatterplot smoothing polynomial), the average number of weekend deaths versus the average number of weekday deaths, and the SIDS death rate for children of alcohol‐consuming versus non‐alcohol‐consuming mothers.
Findings  These measures indicate that the largest spikes in alcohol consumption and in SIDS (33%) occur on New Year, alcohol consumption and SIDS increase significantly on weekends, and children of alcohol‐consuming mothers are much more likely to die from SIDS than are children of non‐alcohol‐consuming mothers.
Conclusions  Alcohol consumption appears to be a risk factor for sudden infant death syndrome, although it is unclear whether alcohol is an independent risk factor, a risk factor only in conjunction with other known risk factors (like co‐sleeping), or a proxy for other risk factors associated with occasions when alcohol consumption increases (like smoking). Our findings suggest that caretakers and authorities should be informed that alcohol impairs parental capacity and might be a risk factor for sudden infant death syndrome; in addition, future research should further explore possible connections between sudden infant death syndrome and alcohol.

Breastfeeding is a practice which is promoted and scrutinised in the UK and internationally. In this paper we use interpretative phenomenological analysis to explore the experiences of eight, British, first-time mothers who struggled with breastfeeding in the early postpartum period. Participants kept audio diary accounts of their infant feeding experiences across a seven day period immediately following the birth of their infant and took part in related semistructured interviews a few days after completion of the diary. The overarching theme identified was of a tension between the participants' lived, embodied experience of struggling to breastfeed and the cultural construction of breastfeeding as 'natural' and trouble-free. Participants reported particular difficulties interpreting the pain they experienced during feeds, and their emerging maternal identities were threatened, often fluctuating considerably from feed to feed. We discuss some of the implications for breastfeeding promotion and argue for greater awareness and understanding of breastfeeding difficulties, so that breastfeeding women are less likely to interpret these as a personal shortcoming in a manner which disempowers them. We also advocate the need to address proximal and distal influences around the breastfeeding dyad and in particular to consider the broader cultural context in the United Kingdom where breastfeeding is routinely 2 promoted yet often constructed as a shameful act if performed in the public arena.

1. Predicting population dynamics at large spatial scales requires integrating information about spatial distribution patterns, inter-patch movement rates and within-patch processes. Advective dispersal of aquatic species by water movement is considered paramount to understanding their population dynamics. Rivers are model advective systems, and the larvae of baetid mayflies are considered quintessential dispersers. Egg laying of baetids along channels is patchy and reflects the distribution of oviposition sites, but larvae are assumed to drift frequently and far, thereby erasing patterns created during oviposition. Dispersal kernels are often overestimated, however, and empirical tests of such assumptions are warranted because of the pivotal role distribution patterns can have on populations. 2. We tested empirically whether the egg distribution patterns arising from oviposition behaviours persisted and were reflected in the distribution patterns of larval Baetis rhodani. In field surveys, we tested for associations between egg mass and larval densities over 1 km lengths of four streams. A control species, the mayfly Ephemerella ignita, was employed to test for covarying environmental factors. We estimated drift rates directly to test whether larvae dispersed between riffles (patches of high egg mass density) and whether drift rates were density-dependent or density-relatedexpected outcomes if drift erases patterns established by maternal behaviours. 3. Positive associations between egg masses and larval benthic densities were found for neonate and mid-stage larvae of Baetis, but not the control species, suggesting persistence of the patchy distribution patterns established at oviposition. Drift rates were high, and riffles were net exporters of neonate and mid-stage larvae, but drift rates were unrelated to benthic densities and few drifters reached the next riffle. Riffles were sinks for large larvae, suggesting ontogenetic shifts in habitat use, but little long-distance dispersal. 4. Overall, the results suggest that most neonate and mid-stage larvae of B. rhodani remain close to the natal riffle, and late-stage larvae disperse shorter distances than routinely assumed. The persistence of maternal effects on distribution patterns well into juvenile life of an allegedly iconic disperser suggests that traditional models of how dispersal influences the population dynamics of many lotic invertebrates may be incorrect.

Background: Numerous factors like continuous habitat reduction or fragmentation for free-ranging giraffes (Giraffa camelopardalis) as well as e.g. suboptimal housing conditions for animals in captivity might lead to behavioural alterations as part of the overall adaptation process to the changing living conditions. In order to facilitate current and future studies on giraffe behaviour, a comprehensive ethogram was compiled based on existing literature, as well as observations on giraffes in the wild (Hwange National Park, Zimbabwe; Entabeni Game Reserve, South Africa), and in captivity (National Zoological Gardens of South Africa, Pretoria). Findings: The resulting ethogram lists 65 different behavioural patterns, which were described and grouped into seven categories: General activities, Abnormal repetitive behaviours, General interactions, Bull-Cow behaviour, Bull-Bull behaviour, Cow-Bull behaviour, Maternal behaviours, and Interactions by calves. The behaviours were further described regarding a presumed purpose, particularly with respect to social interactions and sexual behaviour. Contradictory descriptions from previous studies were considered and discussed in comparison with our own observations. Conclusions: This ethogram provides a basis for current and future studies by suggesting a terminology which can be used for harmonizing behavioural observations, thus helping to facilitate comparability of future results. Subsequently, a better understanding of the behavioural ecology of giraffes in the wild as well as in captivity could aid future conservation efforts.

Background: Mental health disorders are medical conditions that influence individuals' daily functioning, ability to maintain social relationships, and decrease their quality of life (QOL). Social support is meaningful because it is essential for mental health as well as enhancing psychiatric patients' QOL. Aim This study was to assess the relationship between social support and QOL among psychiatric patients. Subjects and Method A descriptive correlational research design is utilized for the current study. The study subjects are a convenience sample of 115 patients from five psychiatric inpatient units and one outpatient clinic of Port-Said Mental Health Hospital. Three structured interview schedules were utilized to collect the necessary data: Tool I: WHO Quality of Life Scale Bref version, Tool II: The Multidimensional Scale of Perceived Social Support, in addition to a socio demographic and clinical data questionnaire. Results The study revealed that more than half of the psychiatric patients reported low QOL and two thirds of them reported low social support. In addition, there was a statistically significant positive correlation between social support and QOL. It was observed that disease onset, onset of treatment, and previous hospitalization significantly affect the social support level. But, the age, income, employment status, diagnosis, and disease onset significantly affects the QOL. Conclusion and Recommendation It can be concluded that most of psychiatric patients have low social support and QOL. In addition, there is a relation between social support and QOL. Therefore, social support should be an essential part of psychiatric treatment because of its important role in enhancing patients' QOL. The study recommended increasing the awareness of the mental health team about the importance of dealing holistically with psychiatric patients as considering his/her physical, psychological, social, and environmental aspects.

The Marvin and Britner system for classifying caregiver behavior patterns in the preschool Strange Situation is presented to complement the Cassidy and Marvin (1992) preschool child -parent attachment classification system. Participants were 110 mothers and their preschool children (aged 2 to 4 years) with medical risks (epilepsy or mild cerebral palsy) or no diagnosis (i.e., healthy). As coded by reliable, independent raters, there was a highly significant level of concordance between the 5category caregiver and child classifications in the preschool Strange Situation across the medical risk levels. In comparison to other caregivers, mothers classified as secure in their caregiving behavior pattern were rated as more sensitive; they also showed greater delight and were more supportive of their children's exploration. Combinations of the ten, 9-point caregiver rating scales were useful in discriminating among the insecure caregiver patterns.

Objective: There has been little research on women who are parenting while they experience pain and none of this research has focused on mothers with young children. The purpose of this study was to consider relational coping strategies generated by mothers that they used when parenting young children and experiencing pain.Methods: Two-hundred sixty-two mothers participated in this survey research; 171

The aim of this study was to explore motherhood in the context of ED. The research question was: What are mothers' daily life experiences when suffering from ED? An explorative design was used. In-depth interviews (n=8) focused on experiences of motherhood and eating difficulties. Data were interpreted by hermeneutic analysis. The main theme Experiencing guilt as a mother in the context of eating difficulties comprised two themes: Having a guilty conscience in relation to being a good enough mother and Being preoccupied about not involving the children in the eating difficulties. The study illuminates the importance of identifying mothers with eating difficulties and offering them treatment and/or support.

The early nursing-sucking relationship is not to be taken for granted in humans. A number of factors can either facilitate or mitigate its optimal establishment on the mother's or newborn's sides. Among these factors, a morphological feature of human mothers' breaststhe areolar glands (AG)has been identified as potentially important. Three day-old infants display attraction during the presentation of the native secretions of the AG, suggesting that they could influence the newborn's behaviour during breastfeeding. The present study assessed this topic in a sample of 121 Caucasian mother-infant dyads. The areolae of these women were screened during the first 3 postnatal days in parallel with the infant's sucking performance, body weight fluctuations and time to lactation onset. On average, 97% of the women bore AG, 80.2% having 1-20 units per areola and 33% showing AG excreting a visible fluid. The endowment in AG appeared positively linked with neonatal growth after birth and with the speed of lactation onset: infants of primiparous women with lower AG numbers had a lower weight gain than those of mothers with higher AG numbers. Further, it took longer to primiparae with lower AG counts to set on lactation. This study confirms and extends the fact that AG, in interaction with maternal experience, might influence the initiation of the breastfeeding relationship.

In this chapter we compare the behavior of mothers to their own infants at three to four and nine to ten months of age in five of the societies described in the previous chapters-namely the Gusii of Kenya, Yucatec Mayan of Mexico, Italian, Swedish, and suburban Bostonian. Mothers and infants were observed naturalistically at home. To explain the differences in frequencies of maternal behavior, we examine the demographic, socioeconomic, and cultural contexts of infant care in these societies, asking: Is maternal behavior adaptive, and if so, to which aspects of the environment?

This study examined mother-adolescent conflict as a mediator of longitudinal reciprocal relations between adolescent aggression and depressive symptoms and maternal psychological control. Motivated by family systems theory and the transactions that occur between individual and dyadic levels of the family system, we examined the connections among these variables during a developmental period when children and parents experience significant psychosocial changes. Three years of self-report data were collected from 168 mother-adolescent dyads, beginning when the adolescents (55.4% girls) were in 6th grade. Models were tested using longitudinal path analysis. Results indicated that the connection between adolescent aggression (and depressive symptoms) and maternal psychological control was best characterized as adolescent-driven, indirect, and mediated by mother-adolescent conflict; there were no indications of parent-driven indirect effects. That is, prior adolescent aggression and depressive symptoms were associated with increased conflict. In turn, conflict was associated with increased psychological control. Within our mediation models, reciprocal direct effects between both problem behaviors and conflict and between conflict and psychological control were also found. Additionally, exploratory analyses regarding the role of adolescent gender as a moderator of variable relations were conducted. These analyses revealed no gender-related patterns of moderation, whether moderated mediation or specific path tests for moderation were considered. This study corroborates prior research finding support for child effects on parenting behaviors during early adolescence.

This study examines cultural patterning in situational variability in mother-infant interactions among middleclass Anglo and Puerto Rican mothers and their 12 to 15-month-old firstborn children. Forty mothers were interviewed regarding their long-term socialization goals and childrearing strategies, and videotaped interacting with their infants in four everyday settings: feeding, social play, teaching, and free play. Results suggest that:

Objective: to describe how women's maternal health, particularly at a psychosocial level, is assessed and promoted during the postnatal hospital stay. Design: postal survey of public hospitals providing postnatal care and interviews with care providers. Setting: all publicly funded maternity units and selected health professionals in Victoria, Australia. Participants: hospital postal survey: sixty six hospital respondents; interviews: 38 maternity unit managers, clinical midwives and medical practitioners. Findings: there was little consistency across the State in relation to routine observations of the mother. Physical checks were much more common than enquiring about how women felt physically. Practice in psychosocial assessment was also diverse, with care plans/maps (clinical pathways) being the main tool to guide assessment. Most participants reported that psychosocial assessment was undertaken during pregnancy. Follow-up after birth also varied. Hospital respondents reported that emotional well-being is assessed postnatally by observation and conversation with women. Participants who were interviewed reported that midwives had mixed skills in assessing and dealing with complex psychosocial issues. Three hospitals administer the Edinburgh Postnatal Depression Scale to women in the days after birth, and three hospitals provide routine sessions of structured debriefing. Survey participants reported that the busy and, at times, chaotic nature of postnatal wards affected the provision of care and the level of psychosocial support offered to women. Key conclusions: although one of the stated aims of early postnatal care is the promotion of maternal well-being, the diversity of practices and the routine nature of many of these practices suggest that care is often not individualised or woman-centred. The reliance of detecting and managing women with particular psychosocial issues during pregnancy results in this aspect of care being given less priority postnatally than may be ideal. Implications for practice: strategies are required to provide health professionals with guidelines and skills to enhance the detection of women who have, or have the potential to develop, health problems after birth. This requires a reorganisation of the way early postnatal care is provided in relation to the use of routine practices; the ability of

Little is known about premature infants' feeding skill development and the contribution to it of biologic and environmental conditions. Aims: Explore the level and variation in feeding skill performance through the first post-term year and examine the contribution to performance of infant neonatal condition and rate of weight gain per day, maternal feeding behavior, and its interaction with neonatal condition.

Objective  This randomized control trial examined the effects of a short-term, interaction-focused and attachment-based video-feedback intervention (VIPP: video-feedback intervention to promote positive parenting).Design  VIPP effect on mothers' sensitive responsiveness and infant–mother attachment security was evaluated in a sample (n = 54) of low sensitive, non-clinical, middle class Lithuanian mothers.Methods  Maternal sensitivity was assessed in a free play session with the Ainsworth's sensitivity scale, and attachment security was observed using the Attachment Q sort for home observations.Results  We found that the intervention mothers indeed significantly improved their sensitive responsiveness through participation in our VIPP. The effect size was large according to Cohen's criteria, d = 0.78. VIPP enhanced maternal sensitive responsiveness even when maternal age, educational level, depression, daily hassles, efficacy, infant gender, and infant negative and positive affect were controlled for. However, attachment security in the VIPP infants was not enhanced after the intervention, compared with the control infants, and the infants did not seem to be differentially susceptible to the increase in maternal sensitivity dependent on their temperamental reactivity.Conclusion  We suggest that a relatively brief and low-cost programme can provide effective support for mothers who lack sensitivity in the interactions with their infants.

Background: Listening to music has a stress-reducing effect in surgical procedures. The effects of listening to music immediately before a cesarean section have not been studied. The objective of this study was to assess the effects of listening to selected music while waiting for a cesarean section on emotional reactions, on cognitive appraisal of the threat of surgery, and on stress-related physiological reactions. Methods: A total of 60 healthy women waiting alone to undergo an elective cesarean section for medical reasons only were randomly assigned either to an experimental or a control group. An hour before surgery they reported mood, and threat perception. Vital signs were assessed by a nurse. The experimental group listened to preselected favorite music for 40 minutes, and the control group waited for the operation without music. At the end of this period, all participants responded to a questionnaire assessing mood and threat perception, and the nurse measured vital signs. Results: Women who listened to music before a cesarean section had a significant increase in positive emotions and a significant decline in negative emotions and perceived threat of the situation when compared with women in the control group, who exhibited a decline in positive emotions, an increase in the perceived threat of the situation, and had no change in negative emotions. Women who listened to music also exhibited a significant reduction in systolic blood pressure compared with a significant increase in diastolic blood pressure and respiratory rate in the control group. Conclusion: Listening to favorite music immediately before a cesarean section may be a cost-effective, emotion-focused coping strategy. (BIRTH 39:2 June 2012)

Background: The birth of a very premature infant is a critical event in the life of a family and studies have shown that mothers of these infants are at greater risk of psychological distress than mothers of full-term infants. Study design: A total population study of mothers of preterm infants born at less than 32-week gestation at a tertiary referral hospital. Subjects and methods: Sixty-two mothers of very preterm infants (< 32 weeks) participated in the present study which examines correlates of maternal depressive symptomatology at 1 month following very premature birth. Information was obtained from structured questionnaires completed by mothers at 1 month after infant admission to neonatal intensive care. Results: Forty percent of the mothers reported significant depressive symptoms on the Edinburgh Postpartum Depression Scale (EPDS). Logistic regression analysis indicated that high maternal stress resulted in an increased likelihood of depressive symptoms (OR 1.15, CI 1.04-1.26, p < 0.01). Higher levels of maternal education (p < 0.05), and increased perception of support from nursing staff (OR 1.06, CI 0.88-1.00, p < 0.05) resulted in decreased likelihood of depressive symptoms. Conclusions: The birth and subsequent hospitalisation of a very premature infant evokes considerable psychological distress in mothers. These results have implications for policy development in order to enhance family centred care in the neonatal intensive care.

Objectives: This paper examines the effectiveness of the Healthy Families New York (HFNY) home visiting program in promoting parenting competencies and preventing maladaptive parenting behaviors in mothers at risk for child abuse and neglect. Methods: The study used microlevel observational assessments of mother-child interactions in the third wave of a randomized controlled trial to evaluate whether mothers who received home visiting services were more likely to exhibit positive parenting and less likely to display negative parenting behaviors than those who did not receive these services. Women were randomly assigned during pregnancy or shortly after the birth of the target child to an intervention group that was offered home visiting services or a control group that was given referrals to other services. At Year 3, 522 mother and child pairs were systematically observed while they interacted in semistructured tasks presenting varied parenting challenges. The study also sought to replicate a finding from Year 2, which revealed that program effects on harsh parenting were stronger among young, first-time mothers who were randomly assigned during pregnancy (the High Prevention Opportunity subgroup) than among the other mothers (the Limited Prevention Opportunity subgroup). Results: Results indicate that HFNY was effective in fostering positive parenting, such as maternal responsivity and cognitive engagement. With respect to negative parenting, HFNY mothers in the High Prevention Opportunity subgroup were less likely than their counterparts in the control group to use harsh parenting, while no differences were detected for the Limited Prevention Opportunity subgroup. Conclusion: HFNY was successful in promoting positive parenting among mothers at risk for child abuse and neglect, which may reflect the program's strength-based approach. The replication of the High Prevention Opportunity subgroup as a moderator of program effects on harsh parenting further suggests that HFNY may be more useful for preventing the initiation rather than the recurrence of child abuse and neglect. Practice implications: To optimize service delivery, HFNY should continue to focus on enhancing parent-child interactions, prioritize HFNY services for young, first-time mothers who are offered the program during pregnancy, and investigate effective strategies to reduce negative parenting practices among the Limited Prevention Opportunity subgroup.

Maternal severe mental illness (SMI) disrupts mothereinfant interaction in the immediate postpartum and is associated with less than optimal offspring development. In-patient mother and baby units (MBUs) provide the opportunity of supporting mothers with SMI in developing their relationships with their infants in order to minimise this disruption. One way is through an individualised video feedback intervention, delivered as part of a multidisciplinary inpatient treatment package. The present study prospectively measured changes in mothereinfant interaction following video feedback intervention, during admission to an MBU (N ¼ 49). Comparisons were made with mothereinfant interactions of (1) a community-based ill group of mothers (N ¼ 67) with a mental health diagnosis of similar severity, living at home and without the intervention and (2) a group of healthy mothers (N ¼ 22). Maternal sensitivity and unresponsiveness, and infant cooperativeness and passiveness, were measured from a 3min videotaped play session, using the CARE-Index. Following admission and the video feedback intervention, the MBU mothers (irrespective of diagnosis) and their infants showed improvements in their interactions. Moreover, on discharge the MBU dyads were significantly more sensitive, cooperative and responsive than the community ill group, and as attuned as the healthy group. While the design of the study does not allow us to conclude unequivocally that the video feedback intervention has effects on the outcome for the mothers and babies independent from the whole inpatient therapeutic package, the results do show that the dyadic interaction of mothers with SMI and their infants improves following the focussed treatment package in a specialised MBU.

maternal nestbuilding in Syrian hamsters: Interaction of ovarian steroids and energy demand. PHYSIOL BEHAV 58(1 ) 141 -146, 1995.--To investigate the relationship between energy demand, ovarian hormones, and behavioral thermoregulation, we measured nestbuilding of female Syrian hamsters (Mesocricetus auratus) under conditions where energy demand and circulating ovarian hormone levels varied. Hamsters increased nestbuilding trader conditions of chronically elevated estradiol and progesterone levels (late gestation; ovariectomized animals treated with estradiol ___ progesterone) and increased energy demand (late gestation or cold exposure). When hormone treatments were withdrawn, hamsters gained weight and reduced nestbuilding activity. Nestbuilding was not affected by lactation (characterized by low ovarian steroid levels and high energy demand) or by estrous cycle phase (characterized by relatively transient changes in ovarian steroid levels and subtle changes in energy demand). Thus, nestbuilding in Syrian hamsters was responsive to increased energy demand from cold exposure, late gestation, and to ovarian hormones. However, during lactation and estrous cycles, nestbuilding did not always change predictably according to known changes in energy expenditure and steroid hormone levels. Thus, levels of nestbullding are influenced by factors in addition to ovarian hormones and energy expenditure under some circumstances.

We criticize a view of maternity that equates the natural with the genetic and biological and show how such a practice overdetermines the maternal body and the maternal experience for women who are mothers through adoption and ART (Assisted Reproductive Technologies). As an alternative, we propose a new framework designed to rethink maternal bodies through the lens of feminist embodiment. Feminist embodied maternity, as we call it, stresses the particularity of experience through subjective embodiment. A feminist embodied maternity emphasizes the physical relations of the subjective lived-body rather than the genetic or biological connections. Instead of universalizing claims about the maternal body, embodied maternity looks to communicable experiences and empathetic understanding.

The aim of the study was to investigate the influence of maternal behavior, infant-mother attachment, and behavioral inhibition on the biobehavioral organization of toddlers during a primary non-attachment-related challenging context. In a sample of 76 toddlers, quality of attachment (secure, avoidant, ambivalent, disorganized) was assessed at 12 months. At 22 months, the subjects were observed in a challenging task according to Child Development 49: 547-556], and salivary cortisol was assessed before and afterwards. Behavioral analyses included child task orientation and exploration, help seeking, proximity seeking, and attachment-exploration-balance as well as maternal supportive presence and quality of assistance. Behavioral inhibition was assessed from maternal reports. Findings from concurrent analyses indicate relations between toddler behavior and adrenocortical function and the importance of concurrent maternal support for toddler behavior. Longitudinal analyses showed that quality of attachment predicted task orientation, help seeking behavior, and the quality of the attachment-exploration-balance, while behavioral inhibition was related to approach to the task. In line with previous findings, adrenocortical activation was found only in insecure infants with high behavioral inhibition indicating the function of attachment security as a social buffer against less adaptive temperamental dispositions. Finally, within-group analyses indicated a social regulation pattern in secure toddlers while the behavior of insecure ones was additionally linked to behavioral inhibition and physiological reactivity. ß 2005 Wiley Periodicals, Inc. Dev Psychobiol 46: 293-306, 2005.

The malleability of insecure and disorganized attachment among infants from maltreating families was investigated through a randomized preventive intervention trial. Findings from research on the effects of maltreatment on infant attachment were incorporated into the design and evaluation of the intervention. One-year-old infants from maltreating families~N ϭ 137! and their mothers were randomly assigned to one of three intervention conditions: a! infant-parent psychotherapy~IPP!,~b! psychoeducational parenting intervention~PPI!, and~c! community standard~CS! controls. A fourth group of infants from nonmaltreating families~N ϭ 52! and their mothers served as an additional low-income normative comparison~NC! group. At baseline, mothers in the maltreatment group, relative to the nonmaltreatment group mothers, reported greater abuse and neglect in their own childhoods, more insecure relationships with their own mothers, more maladaptive parenting attitudes, more parenting stress, and lower family support, and they were observed to evince lower maternal sensitivity. Infants in the maltreatment groups had significantly higher rates of disorganized attachment than infants in the NC group. At postintervention follow-up at age 26 months, children in the IPP and PPI groups demonstrated substantial increases in secure attachment, whereas increases in secure attachment were not found for the CS and NC groups. Moreover, disorganized attachment continued to predominate in the CS group. These results were maintained when intent to treat analyses were conducted. The findings are discussed in terms of the utility of translating basic research into the design and evaluation of clinical trials, as well as the importance of preventive interventions for altering attachment organization and promoting an adaptive developmental course for infants in maltreating families.

Infanticide is a reproductive strategy found in many mammals, especially rodents. The proportion of male and female house mice (Mus domesticus) that are either infanticidal or noninfanticidal is strain specific and varies widely from stock to stock. Male house mice also show strain-specific variation in the behavioral mechanisms that inhibit infanticidal individuals from killing their own offspring. The adult offspring generated from reciprocally crossed CF-1 and Wild stock house mice were tested for their behavior toward newborn pups. In male CF-1 x Wild hybrids, the proportion of infanticidal and noninfanticidal males matched with their maternal phenotype, whereas fema!e CF-1 x Wild hybrids exhibited a proportion of behaviors typical of the CF-1 phenotype, regardless of their mother's genotype. Our results suggest three conclusions: first, tJaat infanticide is a highly labile and heritable behavior in both sexes; second, that there is a sex difference in the genetic substrate that regulates the inheritance of infanticidal behavior; and third, that selection pressures in male mice may operate independently on the mechanisms that promote spontaneous infanticidal behavior versus the mechanisms that inhibit infanticide.

A direct link between antenatal maternal mood and fetal behaviour, as observed by ultrasound from 27 to 28 weeks of gestation onwards, is well established. Moreover, 14 independent prospective studies have shown a link between antenatal maternal anxiety/stress and cognitive, behavioural, and emotional problems in the child. This link generally persisted after controlling for post-natal maternal mood and other relevant confounders in the pre-and post-natal periods. Although some inconsistencies remain, the results in general support a fetal programming hypothesis. Several gestational ages have been reported to be vulnerable to the long-term effects of antenatal anxiety/stress and different mechanisms are likely to operate at different stages. Possible underlying mechanisms are just starting to be explored. Cortisol appears to cross the placenta and thus may affect the fetus and disturb ongoing developmental processes. The development of the HPA-axis, limbic system, and the prefrontal cortex are likely to be affected by antenatal maternal stress and anxiety. The magnitude of the long-term effects of antenatal maternal anxiety/stress on the child is substantial. Programs to reduce maternal stress in pregnancy are therefore warranted. q

In the present study, linkages were examined between parental behaviors (maternal practices) at bedtime, emotional availability of mothering at bedtime, and infant sleep quality in a cross-sectional sample of families with infants between 1 and 24 months of age. Observations of maternal behaviors and maternal emotional availability were conducted independently by 2 sets of trained observers who were blind to data being coded by the other. With infant age statistically controlled, specific maternal behaviors at bedtime were unrelated to infant sleep disruptions at bedtime and during the night. By contrast, emotional availability of mothering at bedtime was significantly and inversely related to infant sleep disruption, and, although these links were stronger for younger infants, they were significant for older infants as well. Maternal emotional availability was also inversely linked with mothers' ratings of whether their infants had sleep difficulties. These findings demonstrate that parents' emotional availability at bedtimes may be as important, if not more important, than bedtime practices in predicting infant sleep quality. Results support the theoretical premise that parents' emotional availability to children in sleep contexts promotes feelings of safety and security and, as a result, better-regulated child sleep.
