The purpose of this study was to validate the Japanese version of the Utrecht Work Engagement Scale (UWES-J). Employees from three independent samples completed the questionnaire (total N = 2,334). Confirmatory factor analyses using the multiple-group method revealed that, instead of the original threefactor model, a one-factor model that assumes that all engagement items load on one single factor fitted the data. Moreover, the one-factor structure was invariant across all three samples. Internal consistency of the scale was sufficiently high ( α = .92) and the test-retest reliability with an interval of two months was .66. A series of second-order confirmatory factor analyses to examine construct validity confirmed the hypothesised model, indicating that work engagement was positively related to job satisfaction whereas it was negatively related to strain and burnout. However, as in previous studies, professional efficacy, a component of burnout, loaded on the engagement factor. These results, in general, suggest the reliability (internal consistency and stability), factorial invariance, and construct validity of the UWES-J in three independent samples.Cette étude avait pour objectif de valider la version japonaise de l'Echelle d'Implication au Travail d'Utrecht (UWES-J). 2,334 salariés provenant de trois échantillons indépendants ont rempli le questionnaire. Une analyse factorielle confirmatoire faisant appel à la méthode des groupes multiples a montré que le modèle originel en trois facteurs devait laisser la place à un modèle unifactoriel puisque tous les items d'implication étaient saturés sur un unique facteur qui rendait compte à lui seul des données. En outre, la structure monofactorielle restait identique à elle-même sur les trois échantillons. La consistance interne de l'échelle était suffisamment élevée ( α = .92) et la fidélité test-retest après une période de deux mois était de .66. Une série d'analyses factorielles confirmatoires de second ordre destinées à étudier la validité de construction ont confirmé le modèle hypothétique, indiquant que l'implication dans le travail était en corrélation positive avec la satisfaction professionnelle tandis qu'elle était en relation négative avec la tension nerveuse et le burnout. Comme dans des travaux antérieurs, l'efficacité professionnelle, une composante du burnout, était saturée dans le facteur d'implication. Ces résultats, vont dans le sens de la fidélité (consistance interne et stabilité), de la solidité factorielle et de la validité de construction de l'UWES-J dans ces trois échantillons indépendants.

Abstract. The current study introduces an ultra-short, 3-item version of the Utrecht Work Engagement Scale. Using five national samples from Finland ( N = 22,117), Japan ( N = 1,968), the Netherlands ( N = 38,278), Belgium/Flanders ( N = 5,062), and Spain ( N = 10,040) its internal consistency and factorial validity vis-à-vis validated measures of burnout, workaholism, and job boredom are demonstrated. Moreover, the UWES-3 shares 86–92% of its variance with the longer nine-item version and the pattern of correlations of both versions with 9 indicators of well-being, 8 job demands, 10 job resources, and 6 outcomes is highly similar with an average, absolute difference between correlations of only .02. Hence, it is concluded that the UWES-3 is a reliable and valid indicator of work engagement that can be used as an alternative to the longer version, for instance in national and international epidemiological surveys on employee’s working conditions.

Although workaholism and work engagement are weakly positively related, they constitute two different concepts. More specifically, workaholism has negative consequences across an extended period of 2 years, whereas work engagement has positive consequences in terms of well-being and performance. Hence, workaholism should be prevented and work engagement should be stimulated.

The aim of the present study is to demonstrate the empirical distinctiveness of workaholism and work engagement by examining their relationships with well-being in a sample of 776 Japanese employees. We expected that workaholism is associated with unwell-being (i.e., high psychological distress and physical complaints, low job and family satisfaction, and low job performance), whereas work engagement is associated with well-being. Well-validated questionnaires were used to measure workaholism (DUWAS), work engagement (UWES), and well-being (BJSQ, HPQ). Structural Equation Modeling showed that, as expected, workaholism was positively associated with ill-health (i.e., psychological distress and physical complaints) and negatively associated with life satisfaction (i.e., job and family satisfaction) and job performance. In contrast, work engagement was negatively associated with ill-health and positively associated with life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts, which are negatively and positively related to various indicators of well-being, respectively.

Based on a conceptual analysis, a two-dimensional self-report questionnaire for assessing workaholism (work addiction) is proposed, including (1) working excessively hard and (2) working compulsively. Using independent explorative and confirmative samples that include employees from The Netherlands ( N = 7,594) and Japan ( N = 3,311), a questionnaire is developed and psychometrically evaluated. Results show that both scales (five items each) are internally consistent and that the hypothesized two-factor structure fits to the data of both countries. Furthermore, convergent validity was shown with measures of excess working time and discriminant validity was shown with measures of burnout and work engagement. Workaholics who work excessively hard and compulsively have a high relative risk on burnout and a low relative risk on work engagement. It is concluded that the two-dimensional measure—dubbed the Dutch Workaholism Scale (DUWAS)—is useful tool in future (cross-cultural) research on workaholism.

Purpose – The purpose of this study is to examine how two different types of heavy work investment – work engagement and workaholism – are related to family satisfaction as reported by employees and their intimate partner. Design/methodology/approach – In total, 398 Japanese couples completed self-reported questionnaires including the model variables. One year later, participants reported again on their family satisfaction. Structural equation modelling analyses were used to test the hypotheses. Findings – As hypothesized, work engagement was positively related to work-family facilitation, which, in turn, predicted own and partner's family satisfaction, also one year later. In contrast, workaholism showed a positive relationship with work-family conflict, and had an indirect negative effect on own and partner's family satisfaction. The structural relationships between the variables from husbands to wives were similar to those from wives to husbands. Research limitations/implications – The use of a non-experimental design does not allow for definitive conclusions regarding causality. Practical implications – The findings contribute to the work-family interface literature by showing how experiences built up at work can have a positive or negative impact on one's partner's family satisfaction. The study highlights a growing need to promote work engagement and discourage workaholism within organizations since engagement has positive and workaholism has negative implications for employees' private life. Originality/value – This study clearly shows the differences between two important work experiences – work engagement and workaholism. Using the spillover-crossover model, the study sheds a new light on the process through which employee work engagement and workaholism influence one's partner at home.

ObjectiveThe purpose of this study was to develop a new Internet-based computerized cognitive behavior therapy (iCBT) program in Manga format, the Japanese cartoon, for workers and to examine the effects of the iCBT program on improving subthreshold depression using a randomized controlled trial (RCT) design among workers employed in private companies in Japan.MethodAll workers in a company (n = 290) and all workers in three departments (n = 1,500) at the headquarters of another large company were recruited by an invitation e-mail. Participants who fulfilled the inclusion criteria were randomly allocated to intervention or control groups (N = 381 for each group). A six-week, six-lesson iCBT program using Manga (Japanese comic) story was developed. The program included several CBT skills: self-monitoring, cognitive restructuring, assertiveness, problem solving, and relaxation. The intervention group studied the iCBT program at a frequency of one lesson per week. Depression (Beck Depression Inventory II; BDI-II) was assessed as a primary outcome at baseline, and three- and six-month follow-ups for both intervention and control groups were performed.ResultsThe iCBT program showed a significant intervention effect on BDI-II (t = −1.99, p<0.05) with small effect sizes (Cohen's d: −0.16, 95% Confidence Interval: −0.32 to 0.00, at six-month follow-up).ConclusionsThe present study first demonstrated that a computerized cognitive behavior therapy delivered via the Internet was effective in improving depression in the general working population. It seems critical to improve program involvement of participants in order to enhance the effect size of an iCBT program.Trial RegistrationUMIN Clinical Trials Registry UMIN000006210

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.
