How to weight chronic diseases in multimorbidity indices? Development of a new method on the basis of individual data from five population-based studies

“…For example, the self-reported severity of diseases is often used as a basis to calculate weights [12,40]. By contrast, we empirically derived weights from the impact of diseases on self-reported health status.…”

Illness beliefs and treatment beliefs as predictors of short and middle term outcome in depression

“…The outcome was operationalized using the German versions of the SF-36 (Bullinger and Kirchberger, 1998; Ware and Sherbourne, 1992) and of the CES scale (Center for Epidemiological Studies Depression Scale, Radloff, 1977; German Version ADS; Hautzinger and Bailer, 1993).

Incremental changes in the measure may be infl uenced by disease severity and the treatment context [65] . Establishing the measurement properties of an instrument within any patient group is an ongoing process.…”
