Abstract

Reliability and validity of the Japanese-translated version of the Swedish Demand-Control-Support Questionnaire (J-DCSQ) was examined. The subjects comprised 212 women working in nursery schools. The 17-item J-DCSQ consists of three subscales: psychological demands (PD), decision latitude (DL), and social support (SS). With regard to reliability, one-week test-retest reliability and internal consistency were proved at a sufficient level. Weighted kappa coefficients were near or greater than 0.60 for all items. Intraclass correlation coefficients were greater than 0.80 for all subscales. Cronbach's alphas (mean inter-item correlation) were 0.64 (0.26), 0.63 (0.22), and 0.86 (0.50) for PD, DL, and SS respectively. The scaling and concurrent validity was also established at a satisfactory level. Ceiling or floor effects were not found for any subscales. The J-DCSQ helped us obtain accurate estimates on extreme response distribution. By using the Japanese version of the Job Content Questionnaire for comparison, Spearman's correlation coefficients were estimated to be 0.74, 0.60, and 0.59 for PD, DL, and SS respectively. In contrast, the factorial validity was not shown as originally hypothesized. Factor analysis did not reveal that PD and DL were definitely separated. In addition, both a PD item and a DL item indicated low factor loadings. In conclusion, the present findings exhibited sufficient reliability of the J-DCSQ, while further studies are needed to establish its validity.
