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.
Bahasa Abstract
Saat ini, tidak adanya alat ukur OCD yang tervalidasi di Indonesia menghambat proses diagnosis dan penanganannya. Penelitian ini bertujuan untuk mengevaluasi properti psikometris dan kegunaan dari Florida Obsessive-Compulsive Inventory (FOCI) versi Indonesia dengan meninjau reliabilitas, validitas, dan skor titik-potong optimal dalam memprediksi OCD. Partisipan penelitian ini terdiri dari 384 individu, yang terdiri dari 157 dengan diagnosis OCD, 80 dengan gangguan kecemasan atau gangguan suasana hati sebagai kasus-kontrol, dan 147 individu sehat sebagai komunitas-kontrol. Asesmen yang digunakan untuk menvalidasi FOCI, Obsessive-Compulsive Inventory Revised (OCI-R), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). Reliabilitas test-retest dievaluasi pada 30 pasien OCD dalam 2 minggu. Terdapat konsistensi internal yang kuat pada kelompok OCD untuk FOCI Symptom Checklist dan Severity Scale (Kuder-Richardson 20, KR-20 = .86 dan α = .86), demikian pula untuk reliabilitas test-retest (Intraclass Correlation Coefficient, ICC = .98 (95% CI [.95, .99]) dan ICC = .73 (95% CI [0.49, 0.86]). Kemudian, validitas konvergen dan diskriminan FOCI sedang-hingga-kuat. Analisis faktor konfirmatori juga menemukan struktur faktor unidimensional untuk FOCI Severity Scale. Skor titik potong ≥5 secara optimal memprediksi OCD dengan nilai sensitivity 85% dan specificity 65%. Secara umum, hasil penelitian mendukung penggunaan FOCI versi Indonesia dalam mengevaluasi OCD pada sampel Indonesia.
