A measure of self-care self-efficacy.

Strategies Used by People to Promote Health (SUPPH), a 29-item self-report, is a measure of self-care self-efficacy. Items for the SUPPH were empirically generated, validated by an expert panel, and tested (N = 275) for psychometric properties, factor composition, and convergent and discriminant evidence with existing scales. Good initial psychometric properties were found for the SUPPH and four factors emerged: coping, stress reduction, making decisions, and enjoying life. These factors are consistent with the underlying self-efficacy theory upon which the scale is based.
