Abstract

Objective: To analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) in a sample of Ecuadorian adults. Method: Psychometric study in which factorial validity, measurement equivalence differentiated by gender and internal consistency of the instrument are analyzed. Participants: 406 Ecuadorian adults, 68.47 % women, aged between 18 and 59 years (M = 27.43; SD = 8.20). Results: The oblique two-factor model of the PHQ is confirmed, with the dimensions of depression and anxiety. Furthermore, the measure is equivalent at the scalar level based on gender. Internal consistency is adequate and presents divergent validity with measures of general well-being. Conclusion: The PHQ-4 is a valid and reliable instrument for rapid assessment of anxiety and depression in Ecuadorian adults.
