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

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, crosssectional 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 (chi(2)[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 (alpha = .949, omega = .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.
