To culturally adapt the Patient Health Questionnaire (PHQ-9) for Aymara-speaking populations in Peru and Bolivia and to evaluate its psychometric properties. A study was conducted with a non-probabilistic sample of 1,607 Aymara speakers from Peru (n = 969) and Bolivia (n = 638), aged 18 to 74 years, with both sexes represented. In the first phase, forward and backward translations were carried out, followed by expert review to ensure cultural contextualization, and focus group with Aymara speakers. In the second phase, internal structure validity, external criterion validity, group-based invariance, and reliability were assessed. The Aymara PHQ-9 demonstrated a unidimensional factor structure with satisfactory fit indices (CFI Bolivia ω = 0.943 to 0.942). The Aymara PHQ-9 for Peru and Bolivia demonstrated robust internal structure validity, external validity, measurement invariance, and reliability. This version is therefore recommended for depression screening among Aymara populations.
