Abstract: At present, Indonesia's lack of a validated measure for Obsessive-Compulsive Disorder (OCD) presents a barrier to diagnostic and treatment processes. In the current study, the Indonesian Florida Obsessive-Compulsive Inventory (FOCI) was evaluated in terms of its reliability, validity, and optimal cut-off score in predicting OCD presence. Participants comprised 384 adults, including 157 with OCD, 80 case-controls with anxiety or mood disorders, and 147 healthy controls. Assessments included the FOCI, Obsessive-Compulsive Inventory Revised, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7. Test-retest reliability of the FOCI was evaluated over two weeks amongst 30 OCD patients. Internal consistency within OCD samples for the FOCI Symptom Checklist and Severity Scale was strong (Kuder-Richardson 20, KR-20 = .86 and Cronbach Alpha, α = .86), as was test-retest reliability (Intraclass Correlation Coefficient, ICC = .98 (95% CI [.95, .99]) and ICC = .73 (95% CI [0.49, 0.86]), respectively). Convergent and discriminant validity were moderate-to-strong. Confirmatory Factor Analysis found a unidimensional factorial structure for the FOCI Severity Scale. A cut-off score of ≥5 optimally predicted OCD with a sensitivity of 85% and specificity of 65%. Overall, results support the use of Indonesian FOCI in screening and assessing OCD amongst Indonesian samples.
