Implementation of adolescent family-based substance use prevention programs in health care settings: Comparisons across conditions and programs

The majority of knowledge related to implementation of family-based substance use prevention programs is based on programs delivered in school and community settings. The aim of this study is to examine procedures related to implementation effectiveness and quality of two family-based universal substance use prevention programs delivered in health care settings, the Strengthening Families Program: For Parents and Youth 10–14 (SFP) and Family Matters (FM). These evidence-based programs were delivered as part of a larger random control intervention study designed to assess the influence of program choice vs. assignment on study participation and adolescent substance use outcomes. We also assess the effects of program choice (vs. assignment to program) on program delivery

Long-term Effects of Universal Preventative Interventions on Methamphetamine Use among Adolescents

Setting  Public schools in the Midwest from 1993 to 2004.Participants  Study 1 began with 667 sixth grade students from 33 rural public schools; the follow-up included 457 students. Study 2 began with 679 seventh grade students from 36 rural public schools; the follow-up assessment included 597 students.Interventions  In study 1, schools were assigned to the Iowa Strengthening Families Program (ISFP), Preparing for the Drug Free Years, or a control condition. In study 2, schools were assigned to a revised ISFP (SFP 10-14) plus Life Skills Training (SPF 10-14 + LST), LST alone, or a control condition.Results  Self-reports of lifetime and past-year methamphetamine use were collected at 6½ years past baseline (study 1) and at 4½ and 5½ years past baseline (study 2). In study 1, the ISFP past-year rate was 0.0% compared with 3.2% in the control condition (P = .04). In study 2, SFP 10-14 + LST showed significant effects on lifetime and past-year use at the 4½ year follow-up (eg, 0.5% lifetime use in the intervention condition vs 5.2% in the control condition, P = .006); both SFP 10-14 + LST and LST alone had significant lifetime use effects at the 5½ year follow-up.Conclusion  Brief universal interventions have potential for public health impact by reducing methamphetamine use among adolescents

A Prospective Validation Study of Inclination, Belief, and Context Predictors of Family-Focused Prevention Involvement

Prior research by the authors tested a model of factors influencing parent inclination to participate in parenting interventions. Family context, belief, attitude, and inclination to participate variables from this model were used to predict the actual participation of 1,121 families in assessment and intervention activities of a family-focused preventive intervention research project. Invitations to the project assessment and intervention components were, respectively, about 6 months and 10 months following the initiation of a telephone survey collecting predictor variable data. Logistic regression analyses examining each predictor individually showed that a number of family context, belief, attitude, and inclination variables were predictive of project participation. Subsequently, multiple logistic regressions were conducted, entering variables by blocks corresponding to theoretical model components. These analyses showed that prospectively stated inclination to participate in a parenting intervention and level of education were consistently significant predictors of both assessment participation and intervention enrollment. Implications for both research and practice are discussed
