This study developed and validated a new self-efficacy scale for exercise behavior in Japanese employees. Higher scores on this scale correlated with increased regular physical activity.

Area of Science:

  • Health Psychology
  • Occupational Health
  • Behavioral Science

Background:

  • Self-efficacy is a key determinant of health behaviors, including exercise.
  • Existing measures may not adequately capture exercise self-efficacy across diverse socioeconomic contexts.
  • Developing culturally relevant tools is crucial for effective health interventions.

Purpose of the Study:

  • To develop and validate a reliable and culturally adapted self-efficacy scale for exercise behavior.
  • To assess the psychometric properties of the newly developed scale in a Japanese occupational setting.

Main Methods:

  • A 3-point Likert-type scale was developed using items from previous studies, modified for socioeconomic relevance.
  • The scale was administered to 647 employees in a Japanese manufacturing company.

  • Principal component factor analysis, Cronbach's alpha, and test-retest correlations were used to evaluate reliability and validity.

    • Main Results:

    • Two factors, 'high priority' and 'independent factor', were identified, demonstrating good internal consistency (Cronbach's alpha 0.90 and 0.84).
    • Test-retest reliability was strong for both factors (0.83 and 0.74).
    • Employees who exercised regularly scored significantly higher on the scale, and high self-efficacy scores predicted regular exercise.

    Conclusions:

    • The newly developed self-efficacy scale for exercise behavior is reliable and valid for use in Japan.
    • The scale can differentiate between individuals who exercise regularly and those who do not.
    • Findings support the role of self-efficacy in promoting exercise behavior within an occupational context.
