| Factor / Subscale |

| External Entrapment |

| Internal Entrapment |
11,12,13,14,15,16 |

Response Format
Respondents rate each item using a custom response format.
Response anchors: 0 = Not at all like me, 1 = A little bit like me, 2 = Moderately like me, 3 = Quite a bit like me, 4 = Extremely like me.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 0 to 64. Interpretation guidelines:
- Low Entrapment: 0 – 16
- Moderate Entrapment: 17 – 32
- High Entrapment: 33 – 64
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of High internal consistency (typically Cronbach's alpha > 0.85).
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.
