Abstract

A measurement invariance study was performed on the Life Satisfaction Survey for Apostolic Women Religious (LSSAWR) across age cohorts to support its continued use to assess satisfaction with religious life across an individual sister’s life span, and to conduct intergenerational comparisons within and across congregations worldwide. Unfortunately, measurement invariance (MI) is often assumed rather than tested but is important to determine when comparisons are conducted across groups. Establishing MI produces confidence that the differences observed are a result of real differences between groups rather than a result of group membership. In general, the current study provides evidence that the LSSAWR is MI for life satisfaction across the Silent, Baby Boomer, and Generation X cohorts and should be robust to many types of analyses. Therefore, the continued use of the LSSAWR to provide feedback to individual Sisters and congregations of women religious regarding commitment to religious life and overall life satisfaction is supported. The most notable result was two of the five dimensions of the scale were statistically indistinguishable for the Silent generation, but not for the Baby Boomer or Generation X cohorts. This article discusses the importance of measurement invariance studies and implications for instruments used across the life span with items that could be age sensitive.
