Helping to improve suggestion systems: predictors of making suggestions in companies
研究了一家荷兰公司蓝领工人提出建议的预测因素，发现工作主动性、高层次需求强度、自我效能感和对工作改善的期望是重要正向因素，而建议抑制因素有负向影响。
Predictors of submitting suggestions and their quality were studied in a Dutch company with a well-developed suggestion system (n=207 blue collar workers). A model with person variables (initiative at work, higher order need strength, control aspirations, and interest in work innovation), work characteristics (control and complexity), motives (better work, reward), self-efficacy, and system factors (system inhibitors, system responsiveness, and supervisor support) was developed and tested. They are related to the three process variables, deemed to be important in making a suggestion: having ideas, submitting suggestions and quality of the suggestions. A path analysis revealed that the most important factors related to these process variables were initiative at work, higher order need strength, self-efficacy, expected improvements in work and suggestion inhibitors (negatively).
