Faith-based intervention, change of religiosity, and abstinence of substance addicts

To investigate the effects of developing religiosity on abstinence of substance abuse among recovering addicts in a faith-based and a secular-based treatment program.

Religiosity of recovering addicts was measured using the 38-item Brief Multidimensional Measure of Religiousness/Spirituality at three points in time: at initiation of substance addiction treatment (wave 1), discharge from treatment (wave 2), and 6 months after treatment (wave 3). Latent growth curve modeling was used to assess the dynamic and developing effects of religiosity on after-treatment abstinence. Secular-based treatment emphasized the role of biological, psychological, and environmental determinants of substance abuse and provided detoxification interventions, such as counseling and group therapies, skill training, health care, and social support, however also relying on religious and spiritual growth to help recovery. Faith-based treatment fundamentally emphasized the Christian theory of addiction to consider substance abuse a sin caused by one's spiritual void and separation from God, although it also acknowledged the importance of biological, psychological, and social needs of rehabilitants.

Recovering addicts in faith-based treatment had significantly higher levels of religiosity at each wave (intercept factor) and better religious development across the three waves (slope factor). This contributed to after-treatment abstinence and mediated the effect of treatment mode on after-treatment abstinence.

Service practitioners and researchers should note the importance of dynamic and developing nature of religiosity in relation to the maintenance of abstinence after treatment is completed.
