Supplementary Material - Objectives
The Areas of Worklife Survey (AWS) is widely used to assess organizational factors contributing to burnout. However, evidence regarding its construct and criterion validity has been reported primarily in human service settings. This study evaluated the construct validity of the AWS measurement model and the criterion validity of the AWS–burnout relationship among industrial workers in Thailand.
Methods
In this cross-sectional study, a Thai-language electronic questionnaire was administered to 446 industrial workers between June 2024 and August 2024. Of these, 390 participants (87.4%) completed both the AWS and the Maslach Burnout Inventory–General Survey. Data were analyzed using confirmatory factor analysis within a structural equation modeling framework.
Results
A modified 6-factor (chi-square/degree of freedom [χ²/df], comparative fit index [CFI], Tucker– Lewis index [TLI], root mean square error of approximation [RMSEA], and standardized root mean square residual [SRMR]) AWS model—excluding 5 items and allowing 2 correlated error terms—demonstrated satisfactory fit (χ²(213)=436.02, p<0.001; χ²/df=2.05; CFI=0.94; TLI=0.92; RMSEA=0.053; SRMR=0.053). Convergent validity (composite reliability=0.74–0.87; average variance extracted [AVE]=0.49–0.58) and discriminant validity were acceptable for most dimensions; however, the Fairness dimension (AVE=0.36) and the Reward–Fairness correlation remained problematic. The partial mediation model demonstrated acceptable criterion validity, with all mediation paths—except reward to values—reaching statistical significance.
Conclusions
The AWS is a valid measure for assessing factors contributing to burnout among Thai industrial workers. Nevertheless, further refinement is necessary to ensure strong dimension-specific validity with minimal modification. -
SummaryKey Message
• The Areas of Worklife Survey (AWS) demonstrated acceptable construct and criterion validity for assessing organizational risk factors related to burnout among Thai industrial workers after model refinement. • A modified 18-item, six-factor structure showed good model fit and meaningful associations with burnout dimensions, supporting the AWS as a useful tool beyond human service settings.
