Developing and Evaluating the Integrated Addiction Recovery Model for the Persons\u27 Engagement and Retention in the Recovery Process Among Clinical Populations from Rwanda

Abstract

Background To date, research that has investigated psychosocial processes and mechanisms, which underpin addiction recovery outcomes are scarce. This study sought to develop and test an integrated addiction recovery model for the recovery process while accounting for an individual’s psychosocial context. Methods This predictive study used consecutive sampling strategies to recruit 315 participants from tertiary addiction care settings in Rwanda. Data on the hypothesized model variables and individual’s characteristics were collected with self-reported measures. Structural equation modelling techniques were used to test the model psychometric measures and associations between latent variables. Results Baseline data analyses showed a mean age at first substance use of 18.6 (SD=6.1). Early age at first substance use and individual’s characteristics, such as post-traumatic stress disorder, had a significant effect on later addiction severity with β= -.130, p=. 013 and β= .363; p= Discussion These results establish psychometric properties of the integrated addiction recovery model. The results demonstrate that retention in the addiction recovery process is underpinned by interactions between therapeutic relationships and supportive social networks through the satisfaction of basic psychological needs. However, future research is needed to conduct the model measurement invariance in a different sample
