Group schema therapy: the temporal relationship between early maladaptive schemas and global psychological distress

Abstract

Objective: Schema therapy is an effective treatment for personality disorders (PDs). The theory of schema therapy assumes that the decrease of global psychological distress is mediated by change in Early Maladaptive Schemas. The few studies that have investigated a temporal relationship have produced contradictory results. This study examined the temporal relationship between changes in Early Maladaptive Schemas and global psychological distress in Group Schema Therapy (GST) for patients with personality disorders. Method: Assessments were made of 115 patients at baseline, after 20, 40 and after 60 sessions of treatment. We used the Young Schema Questionnaire (YSQ) to measure the severity of Early Maladaptive Schemas and the Symptom Check List-90 Revisited (SCL-90R) to measure global psychological distress. Linear mixed model analyzes were used to examine the temporal relationship between the initial phase (0–20 and 0–40 sessions) and the later phase (40–60 sessions). Results: Change in Early Maladaptive Schemas does not precede change in global psychological distress. Conversely, global psychological distress does not precede change in Early Maladaptive Schemas; the improvement in both indicators is concurrent. Conclusion: In this study, we could not confirm that the decrease of Early Maladaptive Schemas precedes decrease of global psychological distress. We found a concurrent relationship.
