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, Interdependent.

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 Endorsement: 15 – 45
- Moderate Endorsement: 46 – 75
- High Endorsement: 76 – 105
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Typically ranges from 0.60 to 0.75 for both subscales.
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.
