先前关于社会资本和健康的研究评估了居民区和社区的社会资本，但提出了这个概念是否也应适用于工作场所的问题。本研究报告了工作中社会资本的8项测量的心理测量特性。数据来源于2000-2002年收集的芬兰公共部门研究（N = 48,592）。根据面孔效度，一位不熟悉数据的专家从可用的问卷项目中选择了8个问卷项目用于社会资本量表。信度分析包括内部一致性测试、项目-总相关性测试和rwg指数单位内（inter - rater）一致性测试。研究了与理论相关和不相关构念的关联，以评估聚合效度和发散效度（构念效度）。采用多水平逻辑回归模型探讨自评健康的标准相关效度。建立了个体水平和单位水平社会资本对自评健康的影响模型。量表内部一致性较好（Cronbach’s alpha = 0.88）。rwg指数为0.88，表明单位内一致性显著。该量表与程序公正、工作控制和努力-回报不平衡等概念相近的构念相关，但并非冗余。它与概念上较远的概念，如特质焦虑和工作变化幅度的联系较弱。在多水平模型中，在个人水平社会资本最低和最高四分位数的员工中，自我评价健康不良的年龄调整比值比（OR = 2.42, 95%置信区间（CI）： 2.24-2.61，女性员工OR = 2.99, 95% CI: 2.56-3.50）显著提高。此外，工作单位层面的社会资本较低与自我评价健康状况不佳的可能性较高有关。心理测量技术表明，我们的8项社会资本测量是反映结构和显示与其他变量的假设联系的有效工具。
Prior studies on social capital and health have assessed social capital in residential neighbourhoods and communities, but the question whether the concept should also be applicable in workplaces has been raised. The present study reports on the psychometric properties of an 8-item measure of social capital at work. Data were derived from the Finnish Public Sector Study (N = 48,592) collected in 2000–2002. Based on face validity, an expert unfamiliar with the data selected 8 questionnaire items from the available items for a scale of social capital. Reliability analysis included tests of internal consistency, item-total correlations, and within-unit (interrater) agreement by rwg index. The associations with theoretically related and unrelated constructs were examined to assess convergent and divergent validity (construct validity). Criterion-related validity was explored with respect to self-rated health using multilevel logistic regression models. The effects of individual level and work unit level social capital were modelled on self-rated health. The internal consistency of the scale was good (Cronbach's alpha = 0.88). The rwg index was 0.88, which indicates a significant within-unit agreement. The scale was associated with, but not redundant to, conceptually close constructs such as procedural justice, job control, and effort-reward imbalance. Its associations with conceptually more distant concepts, such as trait anxiety and magnitude of change in work, were weaker. In multilevel models, significantly elevated age adjusted odds ratios (ORs) of poor self-rated health (OR = 2.42, 95% confidence interval (CI): 2.24–2.61 for the women and OR = 2.99, 95% CI: 2.56–3.50 for the men) were observed for the employees in the lowest vs. highest quartile of individual level social capital. In addition, low social capital at the work unit level was associated with a higher likelihood of poor self-rated health. Psychometric techniques show our 8-item measure of social capital to be a valid tool reflecting the construct and displaying the postulated links with other variables.
