Observed parenting behavior with teens: measurement invariance and predictive validity across race

Previous reports supporting measurement equality between European American and African American families have often focused on self-reported risk factors or observed parent behavior with young children. This study examines equality of measurement of observer ratings of parenting behavior with adolescents during structured tasks; mean levels of observed parenting; and predictive validity of teen self-reports of antisocial behaviors and beliefs using a sample of 163 African American and 168 European American families. Multiple-group confirmatory factor analyses supported measurement invariance across ethnic groups for four measures of observed parenting behavior: prosocial rewards, psychological costs, antisocial rewards, and problem solving. Some mean-level differences were found: African American parents exhibited lower levels of prosocial rewards, higher levels of psychological costs, and lower problem solving when compared to European Americans. No significant mean difference was found in rewards for antisocial behavior. Multigroup structural equation models suggested comparable relationships across race (predictive validity) between parenting constructs and youth antisocial constructs (i.e., drug initiation, positive drug attitudes, antisocial attitudes, problem behaviors) in all but one of the tested relationships. This study adds to existing evidence that family-based interventions targeting parenting behaviors can be generalized to African American families.

A randomized trial of Parents Who Care: effects on key outcomes at 24-month follow-up

This study was designed to test the efficacy of Parents Who Care (PWC), a seven-session universal prevention program which includes parenting, youth, and family components designed to prevent substance use and other problem behaviors. Using an intent-to-treat experimental design, this study tests the program efficacy across race within a balanced sample of European American (EA) and African American (AA) youth and their parents (n = 331 n AA = 163; n EA = 168). Families were recruited, randomly assigned to three conditions (group-administered [PA], self-administered with telephone support [SA], and no-treatment control) and the intervention was administered when the adolescents were in the eighth grade. Analyses on key teen outcomes of the Parent's Who Care program at 24-month follow-up are reported here and include perceptions of drug use harm; favorable attitudes about drug use; delinquent and violent behavior; and initiation into cigarette, alcohol, other drug use, or sexual activity. Repeated measures mixed model regressions found no effect of the intervention on rate of change in attitudes about drug use or frequency of delinquent or violent behavior. Regression analyses with multiple imputations for missing data detected group differences in means at 24-month follow-up. Both program formats reduced favorable attitudes toward drug use among youth (SA d = 0.39, PA d = 0.22); and AA youth in the self-administered intervention reported significantly less violent behavior than their control counterparts (d = 0.45). No effects were found for drug use harm or delinquency. Finally, logistic regression predicting a combined outcome measure of initiation of alcohol, tobacco, drug use, and/or sexual activity found AA youth in both the group- and self-administered intervention conditions significantly less likely to initiate substance use and/or sexual activity than those in the control condition. Odds ratios indicated the chances of initiating sex or substance use were reduced by almost 70% (OR = 0.31) for AA teens in the SA condition compared to controls, and 75% (OR = 0.25) for the AA teens in the PA compared to controls.

Participation in “Parents Who Care”: Predicting Program Initiation and Exposure in Two Different Program Formats

Predictors of participation and exposure across two formats of a universal prevention program are examined here. Families of 225 8th-grade students, balanced by race (African American and European American) and gender, were assigned to a parent and adolescent group format (PAG) or a self-administered format (SA). Logistic regression showed greater program initiation in SA than in PAG. Hierarchical regression showed only one variable (parent high-risk behavior) to be associated with lower program exposure in the self-administered format. In contrast, demographic variables (e.g., being African American) predicted lower exposure in PAG. Overall, the findings of this study were notable in that most of the variables that have been identified in past research as lowering participation rates were not related to program initiation or level of exposure to either format of Parents Who Care. Further, the self-administered format may be particularly useful to increase program participation for families, even those who are traditionally difficult to reach. Editors' Strategic Implications: The authors make a promising contribution to the literature on program engagement by presenting experimental data highlighting different risk factors for nonparticipation across program formats. Their discussion of barriers will help program designers and practitioners decide on the most appropriate strategies for the dissemination of prevention-related materials to parents.

Reducing Playground Bullying and Supporting Beliefs: An Experimental Trial of the Steps to Respect Program

Six schools were randomly assigned to a multilevel bullying intervention or a control condition. Children in Grades 3-6 (N=1,023) completed pre- and posttest surveys of behaviors and beliefs and were rated by teachers. Observers coded playground behavior of a random subsample (n=544). Hierarchical analyses of changes in playground behavior revealed declines in bullying and argumentative behavior among intervention-group children relative to control-group children, increases in agreeable interactions, and a trend toward reduced destructive bystander behavior. Those in the intervention group reported enhanced bystander responsibility, greater perceived adult responsiveness, and less acceptance of bullying/aggression than those in the control group. Self-reported aggression did not differ between the groups. Implications for future research on the development and prevention of bullying are discussed.

Use of the Programma 101 desk-top computer in radioimmunoassay and liquid scintillation calculations

Computer programs for calculating hormonal concentrations from standard radioimmunological procedures and for obtaining disintegrations per minute from liquid scintillation counting data are described. The procedures are accurate, convenient, and easily adapted to methods used in many laboratories.
