Incidents of discrimination and risk for delinquency: A longitudinal test of strain theory with an African American sample

This article examines the relationship between racial discrimination and delinquency. Using longitudinal data collected on approximately 700 African American children, we begin by establishing an association between exposure to discrimination and delinquent behavior. Next, we use structural equation modeling to test various hypotheses regarding the emotional and cognitive factors that mediate this association. For boys, the association between discrimination and delinquency is mediated by feelings of anger and depression and by the belief that aggression is a necessary interpersonal tactic. The results are somewhat different for girls. Although anger and depression mediate part of the effect of discrimination on delinquency, discrimination continues to display a small but significant direct effect. The implications of these findings for criminological theory are discussed.

The Strong African American Families Program: A Cluster-Randomized Prevention Trial of Long-Term Effects and a Mediational Model.

The Strong African American Families Program, a universal preventive intervention to deter alcohol use among rural African American adolescents, was evaluated in a cluster-randomized prevention trial. This 7-week family skills training program is based on a contextual model in which intervention effects on youth protective factors lead to changes in alcohol use. African American 11-year-olds and their primary caregivers from 9 rural communities (N = 332 families) were randomly selected for study participation. Communities were randomized to prevention and control conditions. Intent-to-treat analyses indicated that fewer prevention than control adolescents initiated alcohol use; those who did evinced slower increases in use over time. Intervention-induced changes in youth protective factors mediated the effect of group assignment on long-term changes in use.

It Takes a Village: Protecting Rural African American Youth in the Context of Racism

Prior research demonstrates negative consequences of racism, however, little is known about community, parenting, and intrapersonal mechanisms that protect youth. Using a mixed-methods approach, this study illuminated linkages between positive and negative contextual influences on rural African American adolescent outcomes. Quantitative results provide support for Structural Ecosystems Theory, in that the influence of discrimination and collective socialization on adolescent outcomes was mediated by racial socialization and positive parenting. Parenting and community influences contributed to adolescent racial identity and self image, which protected against common negative responses to racism; including academic underachievement, succumbing to peer pressure, and aggressive tendencies. Qualitative results indicate that current measures of discrimination may underestimate adolescents’ experiences. Adolescents reported racist experiences in the domains of school, peers, and with the police (males only). Moreover, qualitative findings echoed and expanded quantitative results with respect to the importance of the protective nature of parents and communities.

Cumulative socioeconomic status risk, allostatic load, and adjustment: a prospective latent profile analysis with contextual and genetic protective factors.

The health disparities literature has identified a common pattern among middle-aged African Americans that includes high rates of chronic disease along with low rates of psychiatric disorders despite exposure to high levels of cumulative socioeconomic status (SES) risk. The current study was designed to test hypotheses about the developmental precursors to this pattern. Hypotheses were tested with a representative sample of 443 African American youths living in the rural South. Cumulative SES risk and protective processes were assessed at ages 11-13 years; psychological adjustment was assessed at ages 14-18 years; genotyping at the 5-HTTLPR was conducted at age 16 years; and allostatic load (AL) was assessed at age 19 years. A latent profile analysis identified 5 profiles that evinced distinct patterns of SES risk, AL, and psychological adjustment, with 2 relatively large profiles designated as focal profiles: a physical health vulnerability profile characterized by high SES risk/high AL/low adjustment problems, and a resilient profile characterized by high SES risk/low AL/low adjustment problems. The physical health vulnerability profile mirrored the pattern found in the adult health disparities literature. Multinomial logistic regression analyses indicated that carrying an s allele at the 5-HTTLPR and receiving less peer support distinguished the physical health vulnerability profile from the resilient profile. Protective parenting and planful self-regulation distinguished both focal profiles from the other 3 profiles. The results suggest the public health importance of preventive interventions that enhance coping and reduce the effects of stress across childhood and adolescence.

Linking Parental Socialization to Interpersonal Protective Processes, Academic Self-Presentation, and Expectations among Rural African American Youth

Data obtained from 2 waves of a longitudinal study of 671 rural African American families with an 11-year-old preadolescent were used to examine pathways through which racial and ethnic socialization influence youth self-presentation, academic expectations, and academic anticipation. Structural equation modeling analyses indicated that racial and ethnic socialization were linked with youth expectations for and anticipation of academic success through youth self-pride, which included racial identity and self-esteem, and through academic self-presentation. The results highlight the need to disaggregate racial and ethnic socialization to attain a better understanding of the ways in which these parenting domains uniquely forecast youth self-pride and academic orientation.

Family-centered Program Deters Substance Use, Conduct Problems, and Depressive Symptoms in Black Adolescents

Objectives: The present research addressed the following important question in pediatric medicine: Can participation in a new family-centered preventive intervention, the Strong African American Families–Teen (SAAF–T) program, deter conduct problems, substance use, substance use problems, and depressive symptoms among rural black adolescents across 22 months? Methods: Data were collected from 502 black families in rural Georgia, assigned randomly to SAAF–T or an attention control condition. The prevention condition consisted of 5 consecutive meetings at community facilities with separate, concurrent sessions for caregivers and adolescents followed by a caregiver-adolescent session in which families practiced skills they learned in the separate sessions. Adolescents self-reported conduct problem behaviors, substance use, substance use problems, and depressive symptoms at ages 16 years (pretest) and 17 years 10 months (long-term assessment). Results: Adolescents who participated in SAAF–T evinced lower increases in conduct problem behavior, substance use, substance use problems, and depressive symptom frequencies than did adolescents in the attention control condition across the 22 months between pretest and long-term assessment. Conclusions: This is the first study to demonstrate efficacy in a prevention program designed to deter conduct problems, substance use, substance use problems, and depressive symptoms among rural black adolescents. Because SAAF–T is a manualized, structured program, it can be easily disseminated to public health agencies, schools, churches, boys’ and girls’ clubs, and other community organizations.

Long-Term Effects of the Strong African American Families Program on Youths' Conduct Problems

PURPOSE The Strong African American Families program, a universal intervention to deter alcohol use among rural African American preadolescents, was evaluated to determine whether it also prevented conduct problems across the 29 months separating the pretest and long-term follow-up assessments. The program is based on a contextual model in which intervention effects on parental behavior and youth protective factors are hypothesized to lead to behavior changes. METHODS African American 11-year-olds (N = 667) and their primary caregivers were randomly selected from public school lists of fifth-grade students and randomly assigned to an intervention (n = 369) or control (n = 298) condition. Intervention families participated in a 7-week family skills training program designed to deter alcohol use. Each meeting included separate, concurrent sessions for parents and children, followed by a joint parent-child session during which the families practiced the skills they learned in their separate sessions. Control families were mailed leaflets regarding early adolescent development, stress management, and exercise. All families completed in-home pretest, posttest, and long-term follow-up interviews during which parent-report and self-report data regarding conduct problems, low self-control, deviance-prone peer affiliations, parenting, and youth protective processes were gathered. RESULTS Intent-to-treat analyses indicated that prevention-group youth were less involved than control-group youth in conduct problems across time. As hypothesized, prevention effects were stronger for youth at greater risk of developing conduct problems. Intervention targeted parenting and youth factors partially accounted for intervention effects among high risk youth. CONCLUSIONS Although the Strong African American Families program was designed to deter underage drinking, it is also effective in preventing the development of conduct problems.

Parenting Practices and Child Adjustment in Different Types of Households A Study of African American Families

This article uses a sample of 867 African American households to investigate differences in parenting practices and child outcomes by type of household. Results indicate that mothers provide similar levels of parenting regardless of family structure. Secondary caregivers, however, show a great deal of variation in quality of parenting. Fathers and grandmothers engage in the highest quality parenting, stepfathers the poorest, with other relatives falling in between. These differences in parenting do not explain family structure differences in child behavior problems. Results suggest that children do best when there are two caregivers in the household, although stepfathers are an exception to this rule. Child behavior problems are found to be no greater in either mother-grandmother or mother-relative families than in households with two biological parents. In terms of risk for child behavior problems, these family forms seem to be functionally equivalent.

Differential susceptibility to prevention: GABAergic, dopaminergic, and multilocus effects

BACKGROUND Randomized prevention trials provide a unique opportunity to test hypotheses about the interaction of genetic predispositions with contextual processes to create variations in phenotypes over time. METHODS Using two longitudinal, randomized prevention trials, molecular genetic and alcohol use outcome data were gathered from more than 900 youths to determine whether prevention program participation would, across 2 years, moderate genetic risk for increased alcohol use conferred by the dopaminergic and GABAergic systems. RESULTS We found that (a) variance in dopaminergic (DRD2, DRD4, ANKK1) and GABAergic (GABRG1, GABRA2) genes forecast increases in alcohol use across 2 years, and (b) youths at genetic risk who were assigned to the control condition displayed greater increases in alcohol use across 2 years than did youths at genetic risk who were assigned to the prevention condition or youths without genetic risk who were assigned to either condition. CONCLUSIONS This study is unique in combining data from two large prevention trials to test hypotheses regarding genetic main effects and gene × prevention interactions. Focusing on gene systems purported to confer risk for alcohol use and abuse, the study demonstrated that participation in efficacious prevention programs can moderate genetic risk. The results also support the differential susceptibility hypothesis that some youths, for genetic reasons, are more susceptible than others to both positive and negative contextual influences.

Effects of Family Risk Factors on Dosage and Efficacy of a Family-centered Preventive Intervention for Rural African Americans

This study was designed to test hypotheses about family risk factors and their links to dosage and efficacy of a family-centered preventive intervention. Participants were 172 families with an 11 year-old child randomly assigned to the intervention condition in the Strong African American Families Program (SAAF). Two family risk factors, ratio of adults to children in the household and youth unconventionality, were negatively related to dosage, defined as number of intervention sessions attended. Dosage, in turn, was associated with changes in targeted parenting behavior across the 7 months between pretest and posttest. The effect of family risk factors on the link between program dosage and changes in parenting behavior was stronger for families experiencing more risks. The results highlight the need for engagement strategies for recruiting and retaining high-risk families in preventive interventions.
