Abstract The main objective of this study is to test the effects over time of three role stress variables (role conflict, role ambiguity and role overload) on the three burnout dimensions (emotional exhaustion, depersonalization and personal accomplishment). Based on theoretical models on burnout and on meta-analytical research, it is hypothesized that the three role stress variables will predict changes over time in emotional exhaustion and depersonalization, but not in personal accomplishment. The results obtained by means of hierarchical regression analysis partially support the hypothesis. The three role stress variables predict emotional exhaustion over time. Role conflict and role overload predict depersonalization over time. Finally, contrary to expectations, role ambiguity predicts personal accomplishment over time.
摘要 本研究的主要目的是检验三种角色压力变量（角色冲突、角色模糊和角色过载）随时间对三种倦怠维度（情绪耗竭、去个性化和个人成就感）的影响。基于倦怠的理论模型和元分析研究，我们假设这三种角色压力变量将预测情绪耗竭和去个性化随时间的变化，但不会预测个人成就感的变化。通过分层回归分析得到的结果部分支持了这一假设。三种角色压力变量可预测情绪耗竭随时间的变化。角色冲突和角色过载可预测去个性化随时间的变化。最后，与预期相反，角色模糊可预测个人成就感随时间的变化。
