Abstract

Background

Short measurement scales are increasingly sought-after for reasons of efficiency and survey fatigue. A short four-item measure of an organization's climate for employee psychological health, the psychosocial safety climate (PSC-4), has gained international usage. However, the psychometric properties of its Japanese version (PSC-4J) are unknown. We examined the reliability and validity of the PSC-4J.

Methods

An online survey containing the Japanese 12-item PSC scale (PSC-12J), from which the PSC-4J derived, and relevant variables (job demands, job resources, and outcomes) was administered to 2200 employees registered with a Japanese online survey provider. Two weeks later, the PSC-12J was measured again with a follow-up survey of 1400 respondents. Internal consistency and test-retest reliability were examined by Cronbach's α and intraclass correlation (ICC). Agreement between PSC-4J and PSC-12J was examined by Spearman's correlation. Structural validity was examined by confirmatory factor analysis (CFA) and item response theory (IRT) analysis. Convergent validity was examined by Spearman's correlations of PSC-4J with relevant variables, comparing these results with the PSC-12J.

Results

Cronbach's α and ICC for PSC-4J were 0.91 and 0.68, respectively. Spearman's correlation between PSC-4J and PSC-12J was 0.97. The CFA assuming a one-factor structure showed good model fit. The IRT analysis indicated each PSC-4J item had very high discrimination and appropriate difficulty. Spearman's correlations of PSC-4J with relevant variables were slightly lower than for PSC-12J but in the theoretically expected direction.

Conclusions

The PSC-4J, while slightly inferior to the PSC-12J in psychometric properties, provides comparable measurements with fewer items while maintaining adequate reliability and validity.

日本版心理社会安全气候量表（PSC-4J）的信度和效度

背景：由于效率和调查疲劳的原因，短测量量表越来越受欢迎。社会心理安全气候（PSC-4）是衡量组织员工心理健康气候的一个简短的四项指标，已在国际上得到使用。然而，其日文版本（PSC-4J）的心理测量特性尚不清楚。我们检查了PSC-4J的可靠性和有效性。方法：采用日语12题PSC量表（PSC- 12j）和相关变量（工作需求、工作资源和结果）对在日本在线调查提供商注册的2200名员工进行在线调查，PSC- 4j由此衍生。两周后，又对1400名受访者进行了PSC-12J测试。采用Cronbach’s α和类内相关（ICC）检验内部一致性和重测信度。PSC-4J和PSC-12J的一致性采用Spearman相关检验。采用验证性因子分析（CFA）和项目反应理论（IRT）检验结构效度。通过PSC-4J与相关变量的Spearman相关性来检验收敛效度，并将这些结果与PSC-12J进行比较。结果：PSC-4J的Cronbach’s α和ICC分别为0.91和0.68。PSC-4J与PSC-12J的Spearman相关系数为0.97。假设单因素结构的CFA显示出良好的模型拟合。IRT分析显示PSC-4J的每个条目具有很高的辨识度和适当的难度。PSC-4J与相关变量的Spearman相关性略低于PSC-12J，但符合理论预期方向。结论：PSC-4J虽然在心理测量特性上略低于PSC-12J，但在保持足够信度和效度的同时，提供了较少项目的可比较测量。
