This study adapted and validated the DSM-5-Based Premenstrual Symptom Screening Tool (DSM-5 PMS-ST) for Turkish populations. Existing Turkish screening instruments remain anchored to superseded DSM-IV criteria, and menstruation-related stigma may further impede symptom disclosure, underscoring the need for an updated, culturally appropriate assessment tool. A two-phase design was employed: cross-cultural adaptation following systematic translation methodology, and psychometric evaluation among 350 women aged 19–44 years recruited from gynaecology units in Istanbul. The Turkish DSM-5 PMS-ST demonstrated excellent internal consistency (α = 0.88–0.91), good temporal stability (ICC = 0.75–0.82), and a confirmed three-factor structure explaining 62.8% of variance. Strong convergent validity with the Turkish PSST and significant known-groups differentiation across symptom severity levels ( d = 0.96–1.08) were observed. The instrument provides a promising foundation for clinical screening of premenstrual symptoms according to DSM-5 criteria, pending further diagnostic validation and cut-point calibration.
