Response Format
Respondents rate each item using a 5-point Likert scale (1 = Strongly Disagree to 5 = Strongly Agree).
The scale includes 20 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 40 to 200. Interpretation guidelines:
- Low perceived family-of-origin health: 40 – 120
- Moderate perceived family-of-origin health: 121 – 160
- High perceived family-of-origin health: 161 – 200
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.
