This study investigated the distinctiveness between workaholism and work engagement by examining their longitudinal relationships (measurement interval=7 months) with well-being and performance in a sample of 1,967 Japanese employees from various occupations. Based on a previous cross-sectional study (Shimazu & Schaufeli, 2009), we expected that workaholism predicts future unwell-being (i.e., high ill-health and low life satisfaction) and poor job performance, whereas work engagement predicts future well-being (i.e., low ill-health and high life satisfaction) and superior job performance. T1-T2 changes in ill-health, life satisfaction and job performance were measured as residual scores that were then included in the structural equation model. Results showed that workaholism and work engagement were weakly and positively related to each other. In addition, workaholism was related to an increase in ill-health and to a decrease in life satisfaction. In contrast, work engagement was related to a decrease in ill-health and to increases in both life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts that are oppositely related to well-being and performance.
本研究通过考察工作狂和工作投入在幸福感和绩效方面的纵向关系（测量间隔为 7 个月），在来自不同职业的 1967 名日本员工样本中研究了工作狂和工作投入的区别。基于之前的横断面研究（Shimazu & Schaufeli，2009），我们预计工作狂会预测未来的不健康（即高健康不良和低生活满意度）和较差的工作绩效，而工作投入会预测未来的健康（即低健康不良和高生活满意度）和出色的工作绩效。T1-T2 健康状况、生活满意度和工作绩效的变化被测量为残差，然后被纳入结构方程模型。结果表明，工作狂和工作投入之间存在微弱的正相关关系。此外，工作狂与健康状况恶化和生活满意度降低有关。相比之下，工作投入与健康状况恶化呈负相关，与生活满意度和工作绩效的提高呈正相关。这些发现表明，工作狂和工作投入是两个不同的概念，与幸福感和绩效呈相反关系。
