Area of Science:

  • Health Psychology
  • Behavioral Science
  • Psychometrics

Background:

  • Adopting and maintaining health-promoting behaviors is crucial for public health.
  • Existing models like the Stages of Change provide a framework, but predicting long-term adherence requires further refinement.
  • The concept of 'commitment' emerged as a potential predictor of sustained behavior change.

Purpose of the Study:

  • To develop and validate the Commitment to Health Scale (CHS).
  • To assess the reliability and validity of the CHS in predicting health behaviors.
  • To identify 'Commitment to Health' as a distinct, unidimensional construct.

Main Methods:

  • Scale development based on Prochaska and DiClemente's Stages of Change, Decisional Balance, and Strong/Weak Principle.

  • Utilized classical and Rasch measurement methods for item analysis.
  • Conducted three studies with approximately 1100 subjects across the United States.

    • Main Results:

    • Identified and validated 'Commitment to Health' as a unidimensional variable.
    • Achieved high internal consistency reliability (Cronbach's alpha = .94).
    • Demonstrated external validity and reliability through group comparisons and prediction of self-reported behaviors and BMI.

    Conclusions:

    • The Commitment to Health Scale (CHS) is a reliable and valid instrument.
    • CHS scores effectively predict the likelihood of long-term adoption of health behaviors.
    • The findings support the utility of the CHS in health behavior interventions and research.
