Promoting academic achievement: the role of peers and family in the academic engagement of african american adolescents.

While grades are frequently used as indicators of academic achievement, they provide little information about the processes that encourage academic success. Academic engagement, on the other hand, evaluates thoughts, motivations, and behaviors that predict achievement and helps elucidate achievement mechanisms. Understanding academic engagement can facilitate an examination of the forces influencing and hindering achievement and can guide researchers and educators in developing and evaluating effective interventions for increasing academic success. Grounded in ecological theory, this study attempts to understand the influence of family cohesion and peer risky behavior on academic engagement. First, the study explores how socializing with peers who engage in risky behaviors (e.g., sexual behaviors, truancy, or substance use) influences academic engagement and its components (i.e., interest in school, education utility value, and academic effort). Second, the study assesses whether family cohesion buffers the relationship between socializing with these peers and academic engagement. The findings from hierarchical linear regression indicate that socializing with peers who engage in risky behaviors has a significant, negative impact on academic engagement. Family cohesion also was significantly associated with academic engagement over and beyond the effects of risky peers. Implications for families, schools, communities, and programming are discussed.

A re-examination of cultural factors that mitigate risk and promote resilience in relation to African American suicide: a review of the literature and recommendations for future research.

Suicide among African Americans has been acknowledged by the U.S. Surgeon General as a growing crisis. However, suicide remains understudied in this population. In this article, the authors examine the literature related to cultural protective factors that buffer African Americans from suicide risk. They present an overview of suicide among African Americans, review the culture and world-view of African Americans, and examine the degree to which these cultural variables protect against suicide risk. Finally, they discuss the limitations of the extant research on African American suicide, set an agenda for future research, and discuss its implications for clinical practice and public policy.

Autism spectrum disorder in fragile X syndrome: communication, social interaction, and specific behaviors.

The present study extends our previous work on social behavior impairment in young males with fragile X syndrome (FraX). Specifically, we evaluated whether the autistic phenomenon in FraX is expressed as a range of behavioral impairments as in idiopathic autism (Aut). We also examined whether there are behaviors, identified as items of the Autism Diagnostic Interview-Revised (ADI-R), that in FraX predispose to or differentiate subjects with autism spectrum disorder (ASD) diagnosis. Finally, regression models were utilized to test the relative contribution of reduced communication and socialization skills to ADI-R scores and diagnoses. A cohort of 56 boys (3-8 years) with FraX was examined in terms of scores on measures of cognition (IQ was a co-variate in most analyses.), autistic behavior, problem/aberrant behavior, adaptive behavior, and language development. We found that, indeed, in terms of problem behavior and adaptive skills, there is a range of severity from FraX + Aut to FraX + PDD (Pervasive Developmental Disorder) to FraX + none. ADI-R items representing "Play" types of interaction appear to be "susceptibility" factors since they were abnormal across the FraX cohort. Integrated regression models demonstrated that items reflecting complex social interaction differentiated the FraX + ASD (Aut + PDD) subgroup from the rest of the FraX cohort, while abnormalities in basic verbal and non-verbal communication distinguished the most severely affected boys with FraX + Aut from the milder FraX + PDD cohort. Models incorporating language, adaptive communication, and adaptive socialization skills revealed that socialization was not only the main influence on scores but also a predictor of ASD diagnosis. Altogether, our findings demonstrate that the diagnosis of ASD in FraX reflects, to a large extent, an impairment in social interaction that is expressed with variable severity in young males with FraX.
