中高年者に適用可能なワーク・ファミリー・バランス尺度の構成

抄録

A work-family balance scale was developed for middle-aged and elderly individuals. Employed people (N =1,351, 788 men and 563 women; age range, 40 to 85 years; mean age, M = 54.82, SD = 9.86 years) in the seventh study-wave of the National Institute for Longevity Sciences-Longitudinal Study of Aging participated in the study. We hypothesized a four-factor structure consisting of “work-to-family conflict,” “family-to-work conflict,” “work-to-family facilitation,” and “family-to-work facilitation.” An item pool based on previous studies was developed and administered to the participants, and confirmatory factor analysis was conducted on their responses. The results identified 16 items related to work-family balance with a four-factor structure, which supported the hypothesis (GFI = .924, RMSEA = .073). Multiple-group analysis of populations based on age group (middle-aged, elderly) and gender established the configural and measurement invariance of the scale. Moreover, reliability (α = .69―.85) and criterion-related validity were confirmed based on mental health. Furthermore, age (the 40s, 50s, 60s, over 70) and gender differences were partially identified in the four subscales that were developed.
