title: Commitment to Health Scale.
abstract: The Commitment to Health Scale (CHS) was developed to predict likelihood of clients being able to permanently adopt new health-promoting behaviors. Commitment is based on the association between starting new health behaviors and long-term performance of those behaviors. The CHS evolved from an examination of Prochaska and DiClemente's Stages of Change Algorithm, Decisional Balance Scale, and Strong and Weak Principle (Velicer, Rossi, Prochaska, & DiClemente, 1996). Scale items were assessed by classical and Rasch measurement methods. The research was performed in three separate studies at various locations in the United States and included approximately 1100 subjects. A new unidimensional variable was identified called Commitment to Health. Internal consistency reliability of the scale was .94 (Cronbach's alpha). External validity and reliability were assessed based on expected and observed ordering and between known groups. Scale scores predicted self-reported health behaviors and body mass index.
