Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Never, 2 = Not very often, 3 = Slightly less than half the time, 4 = Slightly more than half the time, 5 = Very often, 6 = Always.
The scale includes 8 reverse-scored items to reduce acquiescence bias.

Total scores range from 16 to 96. Interpretation guidelines:
- Low Perceived Control: 16 – 42
- Moderate Perceived Control: 43 – 69
- High Perceived Control: 70 – 96
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Alpha coefficients ranged from 0.65 to 0.80 across samples.
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.
