How useful are the SF-36 sub-scales in older people? Mokken scaling of data from the HALCyon programme.

Journal article

PURPOSE: To evaluate two psychometric properties of SF-36, namely unidimensionality and reliability. METHODS: The data are from three cohorts in the HALCyon collaborative research programme into healthy ageing: Aberdeen Birth Cohort 1936 (n = 428), Hertfordshire Ageing Study (n = 358) and Hertfordshire Cohort Study (n = 3,216).
