This study aims to investigate whether the influence of group cohesion on the outcomes depended on the levels of the therapeutic alliance.
Sixteen individuals with a substance use disorder who were undergoing treatment in a therapeutic community responded to therapeutic alliance, group cohesion, craving and outcomes measures after every therapeutic small group session for a period of six weeks. Data analysis was performed using hierarchical linear modeling.
Results indicate that the effect of group cohesion is stronger when there is a high therapeutic alliance between resident and therapist.
Even on group interventions, to enhance group cohesion effects on outcomes, therapists must foster higher therapeutic alliance levels. The findings point out the importance of studying the effect of common factors on outcomes.
