BACKGROUND: The Seven-Time Dimensions Scale (STDS) assesses daily life rhythms and perceived psychosocial resources, addressing the limitations of traditional symptom-focused tools and meeting the need for a comprehensive assessment for mental-health-related factors. However, as this scale has not been validated in Chinese nurses, the present study evaluates its application in this population.
METHODS: Convenience sampling was used to recruit 1,301 Chinese nurses. Reliability was verified using internal consistency coefficient and split-half reliability. The sample was randomly divided into two independent subsamples for exploratory (Group 1, n = 650) and confirmatory (Group 2, n = 651) factor analyses. To further assess the structural stability and verify the unidimensional structure of STDS, a bifactor confirmatory factor analysis (CFA) and an exploratory structural equation modeling (ESEM) were conducted. Additionally, multigroup confirmatory factor analyses (MG-CFA) were performed across demographic variables to test measurement invariance. Convergent and criterion-related validity were evaluated using Pearson correlations, and incremental variance beyond demographic covariates was assessed using hierarchical regression analyses.
RESULTS: The item-total correlation coefficients ranged from 0.764 to 0.890 (p < 0.001), indicating good internal consistency (Cronbach's α = 0.900; split-half reliability = 0.893). Exploratory factor analysis extracted a single factor accounting for 61.049% of the variance; CFA supported the unidimensional structure (χ²/df = 2.214, RMSEA = 0.043, CFI = 0.993, TLI = 0.990, SRMR = 0.016). A 1-factor ESEM on the confirmatory subsample cross-validated this structure (χ²/df = 2.214, CFI = 0.993, TLI = 0.990, RMSEA = 0.043, SRMR = 0.014), providing further evidence for the stability of the single-factor solution. The bifactor model demonstrated excellent fit (χ²/df = 1.800, CFI = 0.996, TLI = 0.989, RMSEA = 0.035, SRMR = 0.011). The hierarchical ω coefficient (ωh) was 0.896, and the covariation variance explained (ECV) was 0.953, indicating that the general factor explained over 95% of the covariation variance. The MG-CFA results supported full scalar invariance across demographic variables (except for sex and ethnicity) across the full scale (ΔCFI ≤ 0.003, ΔRMSEA ≤ 0.007), suggesting that STDS has strong structural stability across different nurse subgroups. Criterion-related validity analyses revealed that STDS scores were positively correlated with WHO-5, PSSS, and CD-RISC-10 (r = 0.650, 0.492, and 0.555, respectively; p < 0.001) and negatively correlated with the PSS (r = - 0.526, p < 0.001). Hierarchical regression analyses indicated that the scale explained significant incremental variance in the criterion variables beyond demographic covariates.
CONCLUSIONS: STDS demonstrates acceptable reliability and validity as a preliminary measurement tool for assessing daily time experience quality associated with mental-health-related outcomes among Chinese nurses and can be used in future research and practice to develop mental health regulation strategies targeting this population.
