Communication Locus of Control Scale (CLCS)
Measures the degree to which individuals believe their communication successes and failures are due to internal efforts versus external factors.
Scale Development & Technical Details
Scale Overview
The Communication Locus of Control Scale (CLCS) was developed by Hamilton, J. P. (1991). It is designed to measure Communication Locus of Control. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 18 items organized into 2 factors/subscales: Internal Locus of Control, External Locus of Control.
| Factor / Subscale | Items | N |
|---|---|---|
| Internal Locus of Control | 2,9,10,11,12,13,16,17,18 | 9 |
| External Locus of Control | 1,3,4,5,6,7,8,14,15 | 9 |
Response Format
Respondents rate each item using a 4-point Likert scale (1 = Strongly Disagree to 4 = Strongly Agree).
The scale includes 9 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 18 to 72. Interpretation guidelines:
- Low Internal Locus of Control (High External): 18 – 36
- Moderate Locus of Control: 37 – 54
- High Internal Locus of Control: 55 – 72
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 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
