Comparison of HADS-D, PHQ-9 and PHQ-2 for detecting depression in women with polycystic ovary syndrome

OBJECTIVE: To compare depression prevalence using the Hospital Anxiety and Depression Scale focused on depression (HADS-D), the Patient Health Questionnaire-9 (PHQ-9) and the Patient Health Questionnaire-2 (PHQ-2). It also evaluated the psychometric properties of these instruments and their agreement at different cutoff scores. METHODS: ). RESULTS: = 0.599). CONCLUSIONS: Depression rates in PCOS women vary by evaluation technique. This study recommends a cutoff score of ≥7 for the HADS-D and ≥10 for the PHQ-9 to enhance screening accuracy among Thai PCOS women. The PHQ-2 also represents a convenient alternative tool due to its brevity and user-friendliness. We propose that the PHQ-9, with a score of ≥10, constitutes the most suitable screening instrument for Thai women with PCOS.
