Abstract
Objectives: This study reported the development of the Job-Related Uncertainty Stress Scale for Platform Workers (JUSSPW) and examined its reliability and validity.
Methods: The research was conducted in two phases. In Study 1, item analysis and exploratory factor analysis were conducted on data from 343 platform riders (male:321; female:22; mean age:27.03±6.67) in Guangzhou, China. In Study 2, an additional 391 platform riders (male:328; female:63; mean age:30.36±4.49) were recruited. This phase involved conducting confirmatory factor analysis and assessing criterion-related validity by utilizing Uncertainty Stress Scale (USS-4), Maslach Burnout Inventory (MBI), and Job Satisfaction Inventory (JSI).
Results: The JUSSPW scale comprises 8 items under a unidimensional structure, covering four perspectives: work environment, interpersonal relationships, industry-specific characteristics, and personal development prospects, and explained 71.07% of the total variance. CFA results indicated that this one-factor model provided a good fit (χ²/df = 2.681, RMSEA = 0.066, CFI = 0.987, IFI = 0.987, GFI = 0.964, TLI = 0.982). This scale also demonstrated good convergent (AVE = 0.668, CR = 0.941) and criterion validity (AUC= 0.935). The total score of JUSSPW was significantly positively correlated with the USS-4 and MBI-EE scores, and remarkably negatively correlated with the JSI scores. Cronbach’s alpha and split-half reliability were 0.939 and 0.935, respectively.
Conclusions: These results suggested that this scale shows good reliability and validity and can be used as a sound measure to capture platform workers’ job-related uncertainty stress. Limitation and implications were discussed.
