Mexican Quality of Work Life Scale in healthcare personnel: development and validation

Abstract

There is little evidence of measurement scales with appropriate psychometric properties regard Quality of Work-Life in health personnel, so the objective was to develop and examine psychometric properties of Mexican Quality of Work Life Scale (MQWLS). An instrumental, cross-sectional study was conducted. Phase 1) development of the scale and content validity; Phase 2) validation with two different samples [n = 293] and [n = 300] through an online questionnaire. Content validity was obtained for 60 items (Aiken's V > .90); exploratory and confirmatory factor analyzes yielded a six-dimension structure; the fit indexes from the final scale with 24 items were acceptable (χ2[257] = 540.277; CMIN/DF = 2.102; NFI = .914; CFI = .953; GFI = .877, AGFI = .845; SRMR = .047; RMSEA = .061 [.054-.069] p < .001), with good reliability indices (α = .949, ω = .982). MQWLS proved internal consistency reliability, several evidences of validity and acceptable configurational and metric invariance with a model that confirms the existence of six dimensions that explain the construct through 24 items. Existe poca evidencia de escalas de medición con propiedades psicométricas adecuadas respecto a la Calidad de Vida Laboral en el personal sanitario, por lo que el objetivo fue desarrollar y examinar las propiedades psicométricas de la Escala Mexicana de Calidad de Vida Laboral (EMCVL). Se realizó un estudio instrumental y transversal. Fase 1) desarrollo de la escala y validez de contenido; Fase 2) validación con dos muestras diferentes [n = 293] y [n = 300] a través de un cuestionario en línea. Se obtuvo validez de contenido para 60 ítems (V de Aiken > .90); los análisis factoriales exploratorio y confirmatorio arrojaron una estructura de seis dimensiones; los índices de ajuste de la escala final con 24 ítems fueron aceptables (χ2[257] = 540.277; CMIN/DF = 2.102; NFI = .914; CFI = .953; GFI = .877, AGFI = .845; SRMR = .047; RMSEA = .061 [.054-.069] p <.001), con buenos índices de confiabilidad (α = .949, ω = .982). La EMCVL demostró confiabilidad en la consistencia interna, varias evidencias de validez y una invarianza configuracional y métrica aceptable con un modelo que confirma la existencia de seis dimensiones que explican el constructo a través de 24 ítems.
