Self-Construal Scale – SCS
Measures the strength of an individual's independent and interdependent self-construals.
Scale Development & Technical Details
Scale Overview
The Self-Construal Scale – SCS was developed by Theodore M. Singelis (1994). It is designed to measure Independent and Interdependent Self-Construal. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 30 items organized into 2 factors/subscales: Independent Self-Construal, Interdependent Self-Construal.
| Factor / Subscale | Items | N |
|---|---|---|
| Independent Self-Construal | 1,2,5,7,9,10,13,15,18,20,22,24,25,27,29 | 15 |
| Interdependent Self-Construal | 3,4,6,8,11,12,14,16,17,19,21,23,26,28,30 | 15 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = strongly disagree, 2 = moderately disagree, 3 = somewhat disagree, 4 = neutral, 5 = somewhat agree, 6 = moderately agree, 7 = strongly agree.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 15 to 105. Interpretation guidelines:
- Low Construal Strength: 15 – 50
- Moderate Construal Strength: 51 – 75
- High Construal Strength: 76 – 105
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Alpha coefficients typically range from .69 to .74 for Independence and .65 to .74 for Interdependence..
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.
