Patterns of substance use recovery following residential treatment: A repeated measures latent profile analysis

Abstract

IntroductionOngoing improvement to residential treatment for substance use disorders is critical as it typically targets people with the highest need. Assessing multiple recovery indicators, such as cravings and mental health, at intake and following discharge is important in evaluating treatment effectiveness. To refine services, research should explore whether there are subgroups of individuals with different patterns of recovery following treatment.MethodsParticipants (n = 554) were attending Australian Salvation Army residential treatment services for substance use issues. Data were collected by surveys at intake and 3‐month post‐discharge (‘early recovery’). Recovery indicators were cravings, confidence to resist substance use and the Depression, Anxiety and Stress Scale. Subgroups of individuals based on these recovery indicators (‘profiles’) were identified using repeated measures latent profile analysis.ResultsFive profiles were identified, three profiles improved over time (81.4%) and two (18.6%) deteriorated across all indicators. These two profiles had the poorest mental health and addiction scores at intake and reported shorter time in treatment compared to the three profiles showing improvement. There were no demographic or substance type differences between profiles.Discussion and ConclusionsBy considering initial severity and multiple recovery indicators at early recovery, this study suggests that individuals at‐risk of poor early recovery can be identified at intake. This opens opportunities for tailored treatment approaches to address both mental health and substance use, thereby potentially improving treatment outcomes and reducing the risk of relapse.
