When and How Job Design Influences Work Motivation: A Self-Determination Theory Approach

Based on self-determination theory and job characteristics theory, this study aims to provide a systematic and comprehensive model simultaneously investigating the relationship between job characteristics and two forms of work motivation (i.e., controlled motivation and autonomous motivation). To examine the proposed model, we recruited employees working in multiple Chinese industries and collected 435 valid questionnaires. The results indicate that job characteristics have a significantly positive effect on basic psychological needs satisfaction, which, in turn, positively affects autonomous motivation and negatively influences controlled motivation. In addition, basic psychological needs satisfaction mediates the linkage between job characteristics and positive or negative work motivation. Moreover, when an employee had high positive affectivity, job characteristics were more likely to fuel their basic psychological needs satisfaction. In contrast, job characteristics were more likely to be the depressor of these needs satisfaction when an employee possesses high negative affectivity. Our findings revealed that the degree of three needs satisfaction at work is a convincing and identifiable psychological mechanism between job characteristics and two types of work motivation. Also, work affectivity may influence the different perceptions of job characteristics, reminding managers that personality traits are a non-negligible factor in job design. Overall, this paper extends the application of the job characteristics model by revealing when and how job characteristics influence two types of work motivation and further puts forward managerial implications.
