Propiedades psicométricas de la Self-Reporting Questionnaire (SRQ) una versión con 13 ítems para personal de salud del Perú

Objective: To analyze the psychometric characteristics (validity and reliability) of the Self-Reporting Questionnaire (SRQ-13) 13-item version for healthcare personnel who were in face-to-face service during the COVID-19 pandemic. Material and methods: An instrumental study was conducted in a non-probabilistic sample including 4,179 Peruvian participants, mostly women (3,142, 75.2%), aged 20–59 years. The 13-item SRQ, which was implemented in the Technical Guide for Mental Health Care for Healthcare Personnel, was administered. Exploratory Graphic Analysis (EGA) and Confirmatory Factor Analysis (CFA) were used to validate the internal structure; and McDonald's Omega was used to assess reliability. All analyses were performed using R Studio software. Results: We found a structure of four factors related to adequate adjusting indexes (TLI = 0.989, CFI = 0.985, RMSEA = 0.026, 90% CI [0.022 - 0.029], and SRMR = 0.052); likewise, optimal reliability was reported when using the McDonald Omega coefficient in the following dimensions: somatic symptoms (ω = 0.82), anxiety symptoms (ω = 0.77), fatigue (ω = 0.83), and pathological sadness (ω = 0.84). Conclusions: The evidence supports the four-factor model for the SRQ-13, allowing valid and reliable evaluations for assessing somatic symptoms, anxiety, fatigue, and pathological sadness in Peruvian healthcare personnel; therefore, its use is recommended.
