Parents’ Methamphetamine Use: The Pilot-Indigenous SHIFT in Taiwan

Abstract

Introduction: Methamphetamine use poses a significant global public health concern, profoundly affecting family dynamics and child well-being. However, few interventions comprehensively address these dynamics or demonstrate robust effectiveness. This study evaluated the pilot Asian SHIFT intervention model, designed for methamphetamine-affected fathers and mothers, with a focus on reducing parental methamphetamine use and improving family outcomes. Methods: A single-subject design assessed the eight-session training group including pre-, post-, and 6-month follow-up measurements. Seventy methamphetamine-involved parents participated were purposively recruited in deferred prosecution programs. A set of eight section questionnaires including substance use, life stressor, parenting stress and knowledge, family functioning and resilience, and QoL were primary effectiveness outcome measures. Correlation, paired-sample t-tests, and GEE models analyzed continuous repeated measures across three points. Results: The intervention enhanced positive parenting and family functioning. Longitudinal analyses revealed sustained impacts on family resilience, environmental QoL, and reduced drug use. Conclusions: Findings demonstrate the cultural sensitivity, short-term, and sustained effectiveness of SHIFT parent training, meriting further study for optimization.
