Response Format
Respondents rate each item using a 5-point Likert scale (1 = Strongly Disagree to 5 = Strongly Agree).
The scale includes 14 reverse-scored items to reduce acquiescence bias.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 23 to 115. Interpretation guidelines:
- Low Self-Efficacy: 23 – 53
- Moderate Self-Efficacy: 54 – 84
- High Self-Efficacy: 85 – 115
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of General subscale Alpha 0.86, Social subscale Alpha 0.71.
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
