Abstract
The Maladaptive Schema Scale (MSS) was developed to assess dysfunctional cognitive frameworks linked to psychopathology, including personality disorders, trauma, and relational issues, using contemporary theoretical frameworks, addressing limitations in existing schema measures. This study aimed to validate the MSS, evaluate newly proposed schemas, and establish its psychometric properties using Rasch methodology. The scale was assessed in clinical and nonclinical respondents (n = 2,182) for overall and item fit, dimensionality, reliability, and measurement invariance. All 27 MSS schemas had an acceptable overall fit to the Rasch model, no item misfit, no local dependence, evidence of strict unidimensionality, measurement invariance by sex, age, time taken and clinical group, and convergent validity with the Young Schema Questionnaire (YSQ). The MSS is a valid, reliable, and comprehensive tool for assessing maladaptive schemas in clinical and research settings, offering advantages in both brevity and breadth over traditional schema measures.
