The scale includes 9 reverse-scored items to reduce acquiescence bias.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of 0.87 to 0.93 for subscales.
Administration
The scale is self-administered and typically takes approximately 15 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
