Growth Need Strength and Context Satisfactions as Moderators of the Relations of the Job Characteristics Model
使用6405名来自不同岗位的员工样本，检验成长需求强度和四种情境满意度（薪酬、工作保障、同事、监督）对工作特征模型关系的调节作用，发现这些个体差异因素均无显著调节效应。
Empirical investigations of the job characteristics model (JCM; Hackman & Oldham, 1980) have failed to systematically explore the moderating effects of growth need strength (GNS) and context satisfactions (viz., pay, job security, co-worker, and supervision) on the relations among the core job characteristics, critical psychological states, and work outcomes. Previous studies also are criticized for the use of subgroup analytic techniques, low statistical power resulting from small sample sizes (i.e, often less than 200) and/or samples consisting of individuals of relatively homogeneous jobs/occupations. As an attempt to address these deficiencies in the literature, this study examined the moderating effects of GNS and each of the four context satisfactions using a large sample (N = 6405) of employees from a variety of jobs and occupations. Overall, the results of univariate and multivariate hierarchical moderated multiple regression analyses suggest that none of thefive individual difference factors appeared to be viable moderators of any of the relations among job characteristics, psychological states, and three work outcomes (viz., growth satisfaction, overall job satisfaction, and internal motivation). Also, there was no supportive evidence for potential joint moderating effects between GNS and each context satisfaction on the relations of the JCM.
