Does Family Intervention Work for Delinquents? Results of a Meta-Analysis Craig Dowden and D.A. Andrews Maria Giovenco Radford University
Purpose • To explore the effectiveness of family interventions for young offenders, while paying special attention to the concerns raised by Latimer (2001), regarding the impact of methodological rigor on this relationship • Exploration of the roles of the principles of risk, need, and general responsivity in determining the effectiveness of family interventions
Issues to Consider • How an effective treatment program for youth offenders is measured • Risk • Need • General responsivity • How an effective method is measured • Random assignment • A large sample size (N>100) • A follow-up length longer than 1 year • A program evaluator independent of the program
Dependent Measure • Recidivism Rate
Literature Review • Methods • Latimer’s study (2001) • Broader correctional rehabilitation literature (Dowden, 1998) • Studies • 38 were usable
Studies to Include • 53 tests of the effectiveness of family intervention in reducing young offender recidivism were derived from the 38 studies used
Inter-Rater Reliability • Most of the meta-analysis raters agreed with what is correct to include in a good study
Coding For Treatment Variable • 0-Inappropriate service • 1-Weak service • 2-Promising service • 3-Most promising service
Coding for Methodological Quality • Weakest • Fewer than 3 of the elements • Strongest • 3 or 4 of the elements
Overall Results 95% Confidence Interval
Potential Moderators • Type of treatment variable • Inappropriate service • Weak service • Promising service • Most promising service • Methodology used • Random assignment • A large sample size (n>100) • A follow-up length longer than 1 year • A program evaluator independent of the program
Mean Effect Size for Each Level *p<.05 **p<.01
Mean Effect Sizes for Each Level of Type of Treatment ***p<.001
Type of Treatment at Each Level of Methodological Quality Methodological Quality **p<.01
Type of Treatment for Each Indicator of Methodological Quality *p<.05 **p<.01 ***p<.001
Conclusions • Programs that adhere to the principles of risk, need and general responsivity continue to obtain significant mean reductions in recidivism even when evaluated under the strictest of methodological conditions • Family intervention programs must focus on criminogenic familial needs of young offenders, such as increasing family affection/communication and the monitoring/supervision practices of parents
Recommendations • Additional research is necessary in the broader correctional treatment literature • More female offenders need to be studied
