Response Format
Respondents rate each item using a custom response format.
Response anchors: a = Option A, b = Option B.
The scale includes 30 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 0 to 28. Interpretation guidelines:
- Left-wing / Naturalist (Sexual Polarity): 0 – 14
- Right-wing / Jehovanist (Sexual Polarity): 15 – 28
- Left-wing / Humanist (General Polarity): 0 – 10
- Right-wing / Normative (General Polarity): 11 – 21
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Cronbach alpha of .86 for Sexual Polarity, .79 for Tomkins' Polarity Scale.
Administration
The scale is self-administered and typically takes approximately 10 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
