Construct Validity and Reliability of the Work Environment Assessment Instrument WE-10.The purpose of this study was to validate the construct and reliability of an instrument to assess the work environment as a single tool based on quality of life (QL), quality of work life (QWL), and organizational climate (OC). 
WE-10
The methodology tested the construct validity through Exploratory Factor Analysis (EFA) and reliability through Cronbach's alpha.  The EFA returned a Kaiser-Meyer-Olkin (KMO) value of 0.917; which demonstrated that the data were adequate for the factor analysis; and a significant Bartlett's test of sphericity (χ² = 7465.349; Df = 1225; p ≤ 0.000).  After the EFA; the varimax rotation method was employed for a factor through commonality analysis; reducing the 14 initial factors to 10.
