Co-Dependency Inventory – CODI
Measures co-dependency across dimensions of control, dependency, self-alienation, and enmeshment.
Scale Development & Technical Details
Scale Overview
The Co-Dependency Inventory – CODI was developed by S. Stonebrink (1988). It is designed to measure Co-dependency. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 29 items organized into 4 factors/subscales: Need to control, Interpersonal dependency, Self-alienation, Enmeshment.
| Factor / Subscale | Items | N |
|---|---|---|
| Need to control | 1,5,9,13,17,21,25,28 | 8 |
| Interpersonal dependency | 2,6,10,14,18,22,26,29 | 8 |
| Self-alienation | 3,7,11,15,19,23,27 | 7 |
| Enmeshment | 4,8,12,16,20,24 | 6 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 0 = Never, 1 = Sometimes, 2 = Often, 3 = Always.
The scale includes 4 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 87. Interpretation guidelines:
- Low Co-dependency: 0 – 29
- Moderate Co-dependency: 30 – 58
- High Co-dependency: 59 – 87
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Not specified.
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.
