The Family Accommodation Scale (FAS) for OCD helps medical personnel have a clearer and deeper understanding of the pattern of family accommodation. This study aimed to translate FAS into Thai and examine its psychometric properties and factor analysis.Patients and Methods: There were fifty participants who were relatives of OCD patients. Demographic data were collected along with completion of the FAS-T, the Patient Health Questionnaire (PHQ-9), the Pictorial Thai Quality of Life (PTQL), and the Thai Florida Obsessive Compulsive Inventory (FOCI-T), and then analyzed. The severity scales of FOCI-T from 44 OCD patients who had relatives participating in this study were collected from medical records and examined. Psychometric properties and factor analysis of FAS-T were tested.Results: The average total score of FAS-T was 8.36± 8.77 ranging between 0 to 25. The mean scores of FOCI-severity scale in relatives, PHQ-9, PTQL, and FOCI-severity scale in OCD patients, were 1.04± 1.97, 4.04± 3.73, 52.31± 13.99, 8.95± 4.36, respectively. The Cronbach’s coefficient alpha of FAS-T was 0.84, which demonstrated good internal consistency. The item-level CVI and scale-level CVI were at an excellent level. The Spearman’s rho between the FAS and FOCI symptom checklist, FOCI severity score, and PHQ-9 PTQL, were weakly correlated which implied acceptable discriminant validity. Exploratory Factor Analysis (EFA) suggested a three-factor solution as participation, modification, and facilitation.Conclusion: The Family Accommodation Scale for Obsessive–Compulsive Disorder—Interviewer-Rated - Thai version is a psychometrically reliable and valid measure for assessing accommodation in family members of OCD patients.Keywords: family, accommodation, obsessive compulsive disorder, Thai
