Engaging families in longitudinal preventive intervention research: discrete-time survival analysis of socioeconomic and social-emotional risk factors.

This study examined whether family risk factors predicted attrition in a prevention research project that incorporated procedures to increase retention in assessment and intervention activities. Analyses used data from 667 rural families collected over 4 waves and consisted of (a) young adolescent and parent reports of internalizing and externalizing problems, (b) observer ratings of distress in parent-child interactions, and (c) family socioeconomic status (SES). Analyses failed to identify any risk factors as significant predictors of intervention participation. Only SES was found to be significant as a predictor of assessment attrition. This SES result appeared to reflect an association between lower educational attainment and an increased likelihood of attrition.
