Modelling data with ceiling or floor effects
The SF36 is commonly used in epidemiologic studies and is used in ALSWH. However, it was designed to measure medical outcomes among patients with health problems. Young women are generally of good physical health therefore SF36 scores may not detect improvements over time. This study proposes to use Surveys 2-6 (if Survey 6 is available) of the 1973-78 cohort data to examine which longitudinal modelling methods best suit to study the impacts of social support on subsequent physical functioning and subsequent mental health, using continuous measures of the SF36 physical functioning and SF36 mental health subscales.
