Summary

This study developed a brief self-efficacy scale for dietary changes to lower cholesterol. The validated 13-item instrument helps identify individuals likely to respond to interventions.

Area of Science:

  • Health Psychology
  • Behavioral Science
  • Dietary Interventions

Background:

  • Self-efficacy is a key mediator in behavior change, particularly for health-related actions.
  • Dietary modifications are crucial for managing serum cholesterol levels.
  • A validated, brief measure of self-efficacy for dietary changes is needed to support cholesterol management.

Purpose of the Study:

  • To develop and validate a brief self-efficacy scale for individuals aiming to make dietary changes to lower serum cholesterol.
  • To assess the psychometric properties, including factor structure, validity, and reliability, of the newly developed scale.

Main Methods:

  • An initial pool of 37 items was administered to 85 third-year nursing students.
  • Factor analysis identified two primary factors ('self-efficacy for resistance to temptation' and 'self-efficacy for change') comprising 13 items.
  • The 13-item scale was validated in a sample of 125 blue-collar workers, with analyses confirming scale structure and providing evidence of discriminant validity and reliability (Cronbach's alpha 0.7–0.79).

Main Results:

  • The 13-item scale demonstrated a robust two-factor structure, explaining 37% of the variance.
  • Moderate correlations between factors (r = 0.41) and item-scale correlations supported discriminant validity.
  • Reliability analyses indicated acceptable internal consistency for both factors.

Conclusions:

  • The brief, validated self-efficacy scale is a potentially useful adjunct tool for cholesterol modification interventions.
  • The instrument can aid in identifying potential responders to interventions and understanding determinants of dietary behavior change.
  • Findings suggest the scale can guide the tailoring of interventions for specific client or population subgroups.
