Yet, few studies have explored how this risk factor intersects with culturally-specific protective factors, such as racial identity, in a unified cognitive risk-cultural asset model in youth of color. The current study addressed this gap by exploring the interplay between negative inferential style, racial identity, and depressive symptoms in an urban African-American adolescent community sample (N=233; 51.9% female). Cross-lagged panel analyses estimated concurrent and prospective relationships between study variables. Racial identity dimensions of regard, but not centrality, were significant predictors of inferential style, and buffered against the development of depressive symptoms via the development of a less negative inferential style. Implications for the study of racial identity and cognition, and treatment of African-American adolescents are discussed.

Results indicate that there is a significant relation between advancing pubertal stage and depression among girls, and this effect is strongest among White girls. Among boys, risk for depression does not increase with pubertal stage. Importantly, gonadal development appears to be driving the pubertal stage effect. Increasing hormone concentrations, shared environmental stressors, and body esteem appear to be mechanisms of this relation; increases in nonshared environmental stressors (negative life events, peer victimization) moderate the relation between pubertal stage and depression. Inconsistencies in findings across studies can be explained by methodological differences. Future work on this topic should control for age, examine differences by sex, and utilize within-person analyses to evaluate the effect of pubertal stage on depression over time.

To test these hypotheses, we had 87 young adults with high trait reward (HRew) sensitivity or moderate trait reward (MRew) sensitivity report frequency of life events via the Life Event Interview. Brain activation was assessed during the functional MRI monetary-incentive-delay task. Greater exposure to goal-striving events was associated with higher nucleus accumbens (NAc) reward anticipation among HRew participants and lower orbitofrontal cortex (OFC) reward anticipation among MRew participants. Greater exposure to goal-failure events was associated with higher NAc and OFC reward anticipation only among HRew participants. This study demonstrated different neural reward anticipation (but not outcome) following rew...

Participants were 60 university students with a history of repetitive NSSI. At baseline, participants completed an emotional stop-signal task assessing response inhibition to self-harm stimuli. Participants subsequently completed an ecological momentary assessment protocol in which they reported negative affect, urgency, and NSSI urge intensity three times daily over a ten-day period. Impaired emotional response inhibition to self-harm stimuli did not evidence a main effect on the strength of momentary NSSI urges. However, emotional response inhibition to self-harm images interacted with momentary negative affect to predict the strength of real-time NSSI urges, after adjusting for emotional response inhibition to neutral images. Our findings suggest that emotional response inhibition deficits specifically to self-harm stimuli may pose vulnerability for increased NSSI urge intensity during real-time, state-level negative affect.
