Examining Equivalence of Concepts and Measures in Diverse Samples

While there is growing awareness for the need to examine the etiology of problem behaviors across cultural, racial, socioeconomic, and gender groups, much research tends to assume that constructs are equivalent and that the measures developed within one group equally assess constructs across groups. The meaning of constructs, however, may differ across groups or, if similar in meaning, measures developed for a given construct in one particular group may not be assessing the same construct or may not be assessing the construct in the same manner in other groups. The aims of this paper were to demonstrate a process of testing several forms of equivalence including conceptual, functional, item, and scalar using different methods. Data were from the Cross-Cultural Families Project, a study examining factors that promote the healthy development and adjustment of children among immigrant Cambodian and Vietnamese families. The process described in this paper can be implemented in other prevention studies interested in diverse groups. Demonstrating equivalence of constructs and measures prior to group comparisons is necessary in order to lend support of our interpretation of issues such as ethnic group differences and similarities.     

Raising Healthy Children: Examining the Impact of Promoting Healthy Driving Behavior within a Social Development Intervention

This study evaluated the impact of two targeted family sessions focused on driving issues delivered within the context of the Raising Healthy Children project. The Raising Healthy Children project began in the fall of 1993, drawing students in the 1st or 2nd grades from 10 schools. Schools were assigned to an intervention or control condition, and the school-wide, family- and student-focused preventive intervention to address developmentally salient risk and protective factors was delivered during elementary and middle school. The family driving sessions were administered to families in the intervention condition prior to and after teenagers received their driver's license. The first session consisted of a home visit with families designed to help parents and their children improve decision-making skills concerning driving and to develop clear standards and expectations regarding driving-related behavior. A second session, at the time of licensure, was designed to help parents and teens develop a written contract that stated family expectations, a plan for monitoring compliance with these expectations, and consequences for compliance or non-compliance.Consistent with the study's group-randomized design, intervention effects were assessed with multi-level logistic regression models in which students were grouped by their original school assignment. These models assessed specific effects of the driving sessions by adjusting for control variables measured when students were in 8th grade, prior to the driving sessions. Results indicated that students in the intervention group were more likely than students in the control group to report that they had a written driving contract (p = .003, OR = 4.98), and had participated in making the driving rules in the family (p = .025, OR = 1.70). Further, students in the intervention group reported significantly fewer risky behaviors including driving under the influence of alcohol (p = .021, OR = .45) and driving with someone who had been drinking (p = .038, OR = .56).     

Are multiracial adolescents at greater risk? Comparisons of rates, patterns, and correlates of substance use and violence between monoracial and multiracial adolescents

Rates and patterns of substance use and violent behaviors among multiracial adolescents were examined and compared with 3 monoracial groups, European, African, and Asian Americans. The relationships between ethnic identity and the subjective experience of racial discrimination, substance use, and violent behavior were also examined. The authors found multiracial adolescents reporting higher rates of problem behaviors. Several significant relationships between ethnic identity and racial discrimination were found with these problem behaviors.     

Do Social and Behavioral Characteristics Targeted by Preventive Interventions Predict Standardized Test Scores and Grades?

This study assessed whether characteristics of individuals that are predictors of youth problem behavior such as substance use, delinquency, and violence also predict academic achievement. Longitudinal data from 576 students participating in the Raising Healthy Children (RHC) project were analyzed. The RHC project is a study of students recruited from a suburban Pacific Northwest school district. Tenth-grade academic achievement was measured by scores on a standardized test administered to students in Washington State (as part of compliance with the No Child Left Behind Act) and by student self-report of grades. Measures of social and behavioral characteristics at seventh grade were based on data from student, parent, and teacher surveys. Researchers assessed overall correlations between 7th-grade predictors and 10th-grade academic achievement as well as partial correlations adjusted for demographic characteristics and scores on an earlier achievement test, the Comprehensive Test of Basic Skills, in 4th grade. Results indicated that higher levels of school bonding and better social, emotional, and decision-making skills were related to higher test scores and higher grades. Lower test scores and lower grades were predicted by elevated levels of attention problems, negative behavior of peers, and disruptive and aggressive behavior. Lower test scores also were predicted by early use of alcohol and cigarettes. These findings support the premise that school-based social development interventions that address specific risk factors, curb early manifestations of antisocial behavior, and promote school bonding and social and emotional skills are likely to improve student academic achievement.     

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.     

Etiology and Prevention of Substance Use Among Asian American Youth

Among populations identified by the U.S. Bureau of the Census, it is anticipated that the Asian/Pacific Islander (API) population will experience the greatest change between 1990 and 2050 (U.S. Bureau of the Census. [1996, February]. Current population reports. Series P25-1130. Washington, DC: U.S. Government printing office). Limited studies focus on APIs as a racial group and still fewer disaggregate samples to specific ethnic Asian subgroupings. This paper begins with definitions of the API communities, then examines rates of adolescent drug use, risk and protective factors, and preventive intervention effectiveness focused on API communities. The limited epidemiological data suggest that in general, APIs are at a relatively lower risk for drug use than youth from most other ethnic groups. However, the available data also suggest that use may not be as low as generally assumed with rates for alcohol use, smoking, and some illicit drugs being equal to or exceeding those of African Americans and European Americans. Despite the paucity of available data on particular Asian subgroups, the available data demonstrate that there are differences among API subgroups, underscoring the importance of identifying Asian subgroups when studying substance use and when planning prevention and treatment. The limited data examining the etiology of drug use across API subgroups suggests that some of the risk and protective factors derived from majority based research may also be predictors for these populations. These data support the utility of examining the generalizability of existing tested prevention approaches among different API communities. Finally, further efforts should be made to encourage and support the evaluation of community-based programs that already target and deliver services to API youth.     

Family processes for children in early elementary school as predictors of smoking initiation.

OBJECTIVES: To assess the relationship between family processes measured when children are in early elementary school and initiation of cigarette smoking in early adolescence. METHODS: The analysis sample of 810 children was drawn from a longitudinal study of students from a suburban school district in the Pacific Northwest. Predictor variables were assessed when children were in second or third grade, and smoking initiation was measured when the children were in sixth or seventh grade. Measures of family processes were entered separately into logistic regression models that included controls for household structure and income, parent smoking, and peer and child characteristics. RESULTS: Measures of child attachment to parent and parent involvement with the child's school were significantly and negatively associated with smoking initiation. Among control variables, parent smoking, child grade level, and child antisocial behavior and depression were the strongest predictors of smoking initiation. CONCLUSIONS: The results point to the importance of family bonding and parent supportiveness as protective factors and parent smoking and early childhood antisocial behavior and depression as risk factors for smoking initiation in pre- or early adolescence.     

Mobilizing communities to reduce risks for drug abuse: Lessons on using research to guide prevention practice

In May 1988, the authors initiated a risk-focused community mobilization project for drug abuse prevention. That project, TOGETHER! Communities for Drug Free Youth, is a state-wide collaboration involving 28 Washington communities. The project uses current research on risk and protective factors for adolescent drug abuse as its foundation. Through training and technical assistance, communities have been mobilized to design and implement comprehensive, risk-focused plans for adolescent drug abuse prevention. This paper describes the design of the project and examines the extent to which the participating communities formed planning teams that utilized an empirically based risk reduction approach in mobilizing to prevent drug abuse.     

Empowering communities to prevent adolescent substance abuse: Process evaluation results from a risk- and protection-focused community mobilization effort

TOGETHER! Communities for Drug-Free Youth demonstrated the Communities That Care community mobilization strategy for risk-focused prevention of adolescent substance abuse. The project mobilized 35 Oregon communities to conduct quantitative assessments of community risk factors and protective resources, to develop comprehensive prevention plans incorporating promising approaches to priority risk factors, and to implement their plans. At the end of the four-year demonstration, 31 communities remained active in the project, which Oregon has institutionalized. The Communities That Care strategy, process results, and case examples are described. Implications for comprehensive prevention models of adolescent substance abuse and other problem behaviors are explored.
