摘要

Background

Schema Therapy is an integrative psychotherapy model with a growing evidence base in the successful treatment of eating disorders (ED). To specifically assess schema modes in ED, the Schema Mode Inventory for Eating Disorders – Short Form (SMI-ED-SF) was developed but its English adaptation is still lacking.

Objective

The aim of this study is to evaluate the psychometric properties of the English version of the SMI-ED-SF (EN-SMI-ED-SF) within a community sample and to explore its relationship with ED conditions and personality traits.

Method

An observational design was used, recruiting participants from the general population and specialized clinics for ED treatment. A confirmatory factor analysis was performed to test its factorial structure. A multivariate analysis of variance was conducted to ascertain differences between ED conditions on the dimensions of the EN-SMI-ED-SF. Lastly, the relationship between schema modes and personality traits was explored.

Results

The EN-SMI-ED-SF demonstrated excellent fit indices, with robust validity and reliability for measurement of schema modes. Maladaptive schema modes were systematically higher in ED compared to non-ED individuals, and adaptive schema modes were lower in ED groups compared to non-ED individuals. Whereas maladaptive schema modes showed the strongest positive correlations with neuroticism, adaptive modes were strongly correlated with psychological flexibility.

Discussion

The EN-SMI-ED-SF demonstrated robust psychometric properties, indicating its validity and reliability for assessment of schema modes. The results provide strong evidence for the role of schema modes in ED pathology, and their association with key personality correlates and the protective function of psychological flexibility.
