| Περίληψη: | Objectives: To examine the psychometric properties of the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7) in Mexican cancer patients, and to evaluate their utility as brief screening measures for depressive and anxiety symptoms in oncology care. Methods: In this cross-sectional study, 357 adult patients receiving oncological treatment at a cancer hospital in Mexico completed the culturally adapted Spanish versions of the PHQ-9 and GAD-7. Exploratory and confirmatory factor analyses were conducted to assess the factorial structure of both instruments, and internal consistency was evaluated using Cronbach's alpha. Concurrent validity was examined through correlations with related measures. Results: The PHQ-9 yielded a 2-factor structure with acceptable internal consistency (Cronbach's α = 0.837), while the GAD-7 showed a 1-factor structure with good internal consistency (Cronbach's α = 0.881). The PHQ-9 explained 55.3% of the variance and the GAD-7 explained 58.5%. Confirmatory factor analyses indicated adequate model fit for both instruments. Significance of Results: Findings suggest that the PHQ-9 and GAD-7 are brief, valid, and reliable tools for detecting depressive and anxiety symptoms in Mexican cancer patients. Their use may facilitate the early identification of symptoms of anxiety and depression in oncology settings and support both clinical care and psycho-oncology research. |
