Psychometric properties, factorial structure, and measurement invariance of the English and French versions of the Medical Outcomes Study social support scale

This article examines the internal consistency of the English and French versions of the Medical Outcomes Study social support scale for a sample of older adults. The second objective is to conduct a confirmatory factor analysis to assess the factor structure of the English and French versions of the scale. A third purpose is to determine if the items comprising the scale operate in the same way for English- and French-speaking respondents.
