Examining the Psychometric Properties and Clinical Correlates of the Korean Version of the Family Accommodation Scale-Self-Rated Version for Obsessive-Compulsive Disorder

Abstract

Objective We aimed to develop a Korean version of the Family Accommodation Scale-Self-Rated (FAS-SR), to investigate its reliability and validity and to study the clinical correlates of family accommodation in families with obsessive compulsive disorder (OCD) patient.Methods The FAS-SR was translated into Korean under the original author’s supervision. Forty-two patients with OCD and their closest relatives participated. The internal consistency was estimated using Cronbach’s alpha and the split half method. Convergent and divergent validity were identified by measuring with other clinical variables. Test-retest reliability was also calculated.Results The reliability analyses showed that Korean version of the FAS-SR demonstrated excellent internal consistency (Cronbach’s alpha=0.91) and test-retest reliability (Intraclass correlation coefficient=0.93). It showed good convergent validity when simultaneously assessed OCD symptom severity, global functioning and relative’s psychological distress.Conclusion The findings suggest that Korean version of the FAS-SR is a reliable and valid tool for assessing family accommodation in Korean patients with OCD in both research and clinical settings.
