    Objectives. To determine the validity, measurement invariance, and reliability of the Quechua Collao version of the Woman Abuse Screening Tool (WAST) in Peruvian women. Materials and methods: This was a psychometric study aimed at adapting the WAST to Quechua Collao as spoken in the Puno and Cusco regions, using a non-probabilistic sample of 521 women, most of whom (240; 46.1%) were between 18 and 34 years old. The process began with forward and backward translation. Then, five expert judges reviewedthe Quechua Collao version, and a focus group of women confirmed the clarity and comprehension of the items. Confirmatory Factor Analysis (CFA), multigroup CFA for measurement invariance, reliability analysis, and external validity testing using Spearman’s Rho were subsequently conducted. Results. A unidimensional model of the WAST Quechua Collao showed adequate goodness-of-fit indices (CFI = 0.995;TLI = 0.992; SRMR = 0.051; RMSEA = 0.063) and demonstrated measurement invariance across age, educational level, place of residence, and monthly family income (ΔCFI or ΔRMSEA < 0.01). Regarding external validity, the WAST Quechua Collao showed a moderate positive correlation with the Patient HealthQuestionnaire (PHQ-9) (Rho = 0.618, p = 0.000). It also demonstrated excellent reliability, with Cronbach’s alpha (ɑ) = 0.860 and McDonald’s omega (ω) = 0.867. Conclusions. The unidimensional WAST QuechuaCollao version demonstrated internal structural validity, external validity, measurement invariance across age, educational level, place of residence, and monthly family income, as well as excellent reliability. Its useis recommended for screening intimate partner violence among Quechua Collao–speaking women.
