Development and Validation of a New Comprehensive Assessment Scale of HIV-Related Psychological Distress in China: A Methodological Study

Abstract

Instruments evaluating HIV-related psychological distress (HRPD) in people living with HIV may lack sensitivity to capture patients' psychological burden. We developed a comprehensive scale measuring HRPD and evaluated its psychometric properties. A mixedmethod study was conducted from July 2021 to April 2022; it involved a literature review, semistructured interviews (n 5 15), three rounds of panel discussions, two rounds of Delphi studies (n 5 20), a pilot test (n 5 20) to generate new scale items, and a crosssectional survey (n 5 659) to evaluate the psychometric properties of the HIV-related psychological distress scale. The scale contains 22 items across 4 subscales (i.e., disease-related distress, treatment adherence distress, identity distress, and disclosure distress). The confirmatory factor analysis revealed high goodness of fit (x 2 /df 5 2.412, comparative fit index 5 0.916, incremental fit index 5 0.917, and Tucker-Lewis index 5 0.902), showing that the HIV-related psychological distress scale is a reliable (Cronbach's a 5 0.871 overall) and valid scale for evaluating HRPD in China and can be used to dynamically evaluate and monitor HRPD levels during patient follow-up.

Validez de contenido de un instrumento de medición para medir el éxito en la implementación del TPM

“…Por lo tanto, no es posible determinar si la discrepancia observada en cada ítem se debe al azar (Almanasreh et al, 2019). A pesar de su incapacidad para discriminar los efectos de la aleatoriedad en la evaluación de la concordancia en el juicio de los expertos, estos métodos aún se aplican para validar el contenido de los IM (Carlton et al, 2022;Feng et al, 2022;Ma et al, 2023;Reick et al, 2023). Es decir, desde un punto de vista estadístico, los resultados obtenidos al evaluar la validez de contenido de un IM con estos métodos son cuestionables.…”
