Measuring confidence in physician: Adaptation and validation of TPS in HIV individuals from Mexico
##plugins.themes.bootstrap3.article.main##
Resumen
Objetivo. Evaluar las propiedades psicométricas de una versión traducida y adaptada de la Trust in Physician Scale (TPS) en PVVS mexicanas.
Método. Se realizó un estudio transversal en adultos con VIH. La escala fue traducida al español y adaptada culturalmente. Los datos sociodemográficos y de la TPS se recogieron en línea debido a la pandemia de COVID-19. Se realizaron análisis factoriales exploratorios (AFE) y confirmatorios (AFC) en dos muestras diferentes.
Resultados. Se utilizaron los datos de 215 participantes para el AFE. Se eliminaron cinco ítems debido a la baja correlación con la escala total. El alfa de Cronbach final fue de .93. Una estructura unifactorial explicó el 68.8% de la varianza. El AFC en una muestra de 140 participantes confirmó la adecuación del modelo mostrando índices de ajuste adecuados (χ2[7] = 13.015 p = .072, CFI = .997, RMSEA =.057, SMRS = .0015).
Discusión y conclusión. La escala final fue unifactorial y se compuso de seis ítems en lugar de 11. Parece ser una escala válida y fiable para medir la confianza del paciente en los médicos en PVVS mexicanas. Se recomiendan más estudios para buscar evidencia de validez convergente del instrumento.
