Scale Development & Technical Details
Scale Overview
The Academic Self-Concept Scale – ASCS was developed by Herbert W. Marsh (1990). It is designed to measure Academic Self-Concept. The scale is intended for use with Children and adolescents.
Scale Structure
This instrument consists of 8 items organized into 2 factors/subscales: Math Self-Concept, English Self-Concept.
| Factor / Subscale | Items | N |
|---|---|---|
| Math Self-Concept | 1,2,3,4 | 4 |
| English Self-Concept | 5,6,7,8 | 4 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = False, 2 = Mostly False, 3 = More False than True, 4 = More True than False, 5 = Mostly True, 6 = True.
The scale includes 3 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 4 to 24. Interpretation guidelines:
- Low Self-Concept: 4 – 10
- Moderate Self-Concept: 11 – 17
- High Self-Concept: 18 – 24
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of 0.82.
Administration
The scale is self-administered and typically takes approximately 3 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
