Impact of Self-Help Schema Therapy on Psychological Distress and Early Maladaptive Schemas: A Randomised Controlled Trial

Self-help cognitive behaviour therapy has been found helpful in treating anxiety and depression. Recent evidence suggests that self-help schema therapy may represent another treatment alternative. The present study aimed to provide a preliminary assessment of the efficacy of self-help schema therapy on psychological distress and early maladaptive schemas (EMSs) using a 6-week treatment protocol with minimal email contact. Method: Participants were recruited from the general population and randomly assigned to self-help schema therapy (n = 32) or a waitlist (n = 32). Intent-to-treat analyses and study completer analyses were conducted using repeated-measures analyses of variance (time × group). Results: Intent-to-treat analyses revealed that treatment produced a marginal improvement in distress, but no change in EMSs. Among study completers (n = 34), self-help schema therapy yielded large reductions in distress scores on the Outcome Questionnaire-45.2 (partial eta squared = .16). Compared to the waitlist, self-help schema therapy also produced a moderate decrease in EMSs (partial eta squared = .10). The majority of study completers showed reliable clinical change in distress and reported high levels of satisfaction with the intervention. Conclusion: Self-help schema therapy may be an effective treatment for those individuals who persist in treatment. Self-help schema therapy has the potential to help a large number of individuals who may not otherwise have access to services. More research is needed to determine variables associated with treatment adherence and successful outcome.
