Estimating Student Attrition in School-Based Prevention Studies: Guidance from State Longitudinal Data in Maryland.

Attrition is a critical concern for evaluating the rigor of prevention studies, and the current study provides rates of attrition for subgroups of students and schools who are often sampled for prevention science. This is the first study to provide practical guidance for expected rates of attrition using population-level statewide data; findings indicated that researchers using K-12 school-based samples should plan for attrition rates as high as 27% during middle school and 54% during elementary school. However, researchers should consider the grade levels initially sampled, the length of follow-up, and the specific student characteristics and schools available for sampling. Postsecondary attrition ranged from 45% for bachelor's degree seekers to 73% for associate degree seekers. This practical guidance can help researchers to proactively plan for attrition in the study design phase, limiting bias and increasing the validity of prevention studies.

Preventing Adolescent Substance Use: A Content Analysis of Peer Processes Targeted Within Universal School-Based Programs.

Universal school-based substance use prevention programs are widely disseminated and often include a focus on peer relationships. Network theory and social network analysis (SNA) have emerged as useful theoretical and methodological frameworks for examining the role of peer relationships in prevention and intervention research. We used content analysis to systematically code the peer processes targeted by three universal school based prevention programs. We found that programs focused on peer socialization more than peer selection, and programs focused about evenly on descriptive and injunctive norms. Programs varied in their focus on positive and negative peer processes and behaviors, but most references to peer processes focused on positive processes and negative behaviors. The focus on peer processes at the dyadic, subgroup, and network levels varied across the three programs, with the heaviest focus on network level processes. When peer processes were targeted, it was rare that lessons focused on peer processes for an extended (> 50%) amount of the lesson content. However, when peer processes were a focus, discussion and reflection were commonly encouraged. These patterns are considered in the context of non-intervention research on adolescent peer relations, which highlights the importance of peer selection and dyad-level processes, and the existence of positive peer processes that promote adolescent development. In doing so, we provide a framework that can be used to (1) examine the extent to which a particular program focuses on the different peer processes, and (2) inform systematic experimental studies of the extent to which particular peer processes are malleable in response to intervention efforts.

Family Functioning and High Risk Adolescents' Aggressive Behavior: Examining Effects by Ethnicity.

The relationship between family functioning and adolescents' physical aggression has been well established, but whether these relationships might differ by ethnicity has received less attention. Ethnic variations may be important for targeting prevention programs to specific youth and families. This study examined the longitudinal relationship between family cohesion, parental monitoring, and physical aggression using data from the Multisite Violence Prevention Project sample of high-risk youth (elevated aggression). Participants were 1,232 high-risk middle school students (65% male; 70% African American; 15% Hispanic). Meaningful demographic variations were identified. After controlling for intervention condition and study site, family cohesion was significantly negatively related to physical aggression, more so for Hispanic youth. Parental monitoring was negatively associated with physical aggression for African American youth only. Our findings point to the importance of developing culturally sensitive family interventions to prevent physical aggression in middle school.

Delinquency in Adolescent Girls: Using a Confluence Approach to Understand the Influences of Parents and Peers.

Determining the interdependence of family and peer influences on the development of delinquency is critical to defining and implementing effective interventions. This study explored the longitudinal relationship among harsh punishment, positive parenting, peer delinquency, and adolescent delinquency using data from a sub-sample of the Pittsburgh Girls Study. Participants were 622 adolescent girls (42% European American, 53% African American); families living in low-income neighborhoods were oversampled. After controlling for the effects of race, living in a single parent household, and receipt of public assistance, harsh punishment and peer delinquency in early adolescence were positively related to delinquency in mid-adolescence. No significant main effects of positive parenting or interaction effects between parenting and peer delinquency were observed. Thus, the effects of harsh parenting and peer delinquency are independent and perhaps additive, rather than interdependent. Results indicate the continued importance of targeting both parenting and peer relationships to prevent delinquency in adolescent girls.

The longitudinal relationship between peer violence and popularity and delinquency in adolescent boys: examining effects by family functioning.

Mapping the relationship of peer influences and parental/family characteristics on delinquency can help expand the understanding of findings that show an interdependence between peer and family predictors. This study explored the longitudinal relationship between two characteristics of peer relationships (violence and perceived popularity) with subsequent individual delinquency and the moderating role of family characteristics (cohesion and parental monitoring) using data from the Chicago Youth Development Study. Participants were 364 inner-city residing adolescent boys (54% African American; 40% Hispanic). After controlling for the effects of age and ethnicity, peer violence is positively related to boys' delinquency. The effect of popularity depends on parental monitoring, such that the relationship between popularity and delinquency is positive when parental monitoring is low, but there is no relationship when parental monitoring is high. Furthermore, parental monitoring contributes to the relationship between peer violence and delinquency such that there is a stronger relationship when parental monitoring is low. Additionally, there is a stronger relationship between peer violence and delinquency for boys from high cohesive families. Findings point to the value of attention to multiple aspects of peer and family relationships in explaining and intervening in the risk for delinquency. Furthermore, findings indicate the importance of family-focused interventions in preventing delinquency.

Protective factors associated with positive mental health in traditional and nontraditional Black students.

Black students have higher levels of psychological distress compared with other students, in part to racism and discrimination; however, help-seeking remains low. As a result, most research has been deficit-based focusing on mental illness, which provides an incomplete state of their mental health. Therefore, very little is known about positive mental health (PMH), which is composed of social, emotional, and psychological well-being. To better understand their complete state of mental health, this study examined variations in levels of PMH among 235 Black traditional (ages 18 to 25) and nontraditional (ages 26+) college students attending historically Black colleges and universities and predominantly White institutions, in addition to identifying protective mechanisms promoting flourishing within these subgroups. The sample included 156 traditional college students (Mage = 20.88, SD = 2.12; 83% female) and 79 nontraditional college students (Mage = 36.06, SD = 36.1; 80% female). Approximately 54.4% of nontraditional students were flourishing compared with 43.6% of traditional students who were moderately mentally healthy. No significant differences were found in PMH among Black students attending historically Black colleges and universities and predominantly White institutions. Results indicate spirituality, social support, self-esteem, and racial identity (low centrality and high public regard) are associated with PMH in Black traditional students; however, spirituality, self-esteem, and racial identity (high public regard) were associated with PMH in nontraditional students. Our findings emphasize the importance of integrating identified protective mechanisms into existing programs and services to increase levels of flourishing among Black students within the college setting. Implications and recommendations for future research are provided. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Longitudinal associations between emotion regulation and depression in preadolescent girls: moderation by the caregiving environment.

Identifying childhood precursors for depression has been challenging and yet important for understanding the rapid increase in the rate of depression among adolescent girls. This study examined the prospective relations of preadolescent girls' emotion regulation and parenting style with depressive symptoms. Participants were 225 children and their biological mothers recruited from a larger longitudinal community study. Girls' observed positive and negative emotion during a conflict resolution task with mothers, their ability to regulate sadness and anger, and their perception of parental acceptance and psychological control were assessed at age 9. Depressive symptoms were assessed by self-report at ages 9 and 10. The results indicated interactions between child emotion characteristics and parenting in predicting later depression. Specifically, low levels of positive emotion expression predicted higher levels of depressive symptoms in the context of moderate to high parental psychological control. Low levels of sadness regulation were predictive of high levels of depressive symptoms in the context of low to moderate parental acceptance. Findings from this study support the hypothesis that the prospective association between vulnerabilities in emotion regulation and depression are moderated by the caregiving environment.

The Effect of Having Aggressive Friends on Aggressive Behavior in Childhood: Using Propensity Scores to Strengthen Causal Inference.

This study uses propensity scores to statistically approximate the causal effect of having aggressive friends on aggressive behavior in childhood. Participants were 1,355 children (53% girls; 31% minority) in 97 third and fifth grade classrooms enrolled in the Classroom Peer Ecologies Project. Propensity scores were calculated to control for the impact of 21 relevant confounder variables related to having aggressive friendships and aggressive behavior. The 21 variables included demographic, social, and behavioral characteristics measured at the beginning of the school year. Presence/absence of aggressive friends was measured in the middle of the school year, and aggressive behavior was measured at the end of the school year. Results indicate a significant effect of having one or more aggressive friends on children's aggressive behavior above and beyond the effects of the 21 demographic, social, and behavioral variables. The propensity score model is compared to two other models of peer influence. The strengths and practical challenges of using propensity score analysis to study peer influence are discussed.
