Rotter’s Locus of Control Scale
Measures the degree to which individuals believe they have control over the events that affect their lives, distinguishing between internal and external locus of control.
Scale Development & Technical Details
Scale Overview
The Rotter’s Locus of Control Scale was developed by Julian B. Rotter (1966). It is designed to measure Locus of Control. The scale is intended for use with Adults and adolescents.
Scale Structure
This instrument consists of 29 items organized into 2 factors/subscales: Locus of Control, Filler Items.
| Factor / Subscale | Items | N |
|---|---|---|
| Locus of Control | 2,3,4,5,6,7,9,10,11,12,13,15,16,17,18,20,21,22,23,25,26,28,29 | 23 |
| Filler Items | 1,8,14,19,24,27 | 6 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: a = Statement A, b = Statement B.
The scale includes 11 reverse-scored items to reduce acquiescence bias.
Scoring
Items are summed to produce a total score.
Total scores range from 0 to 23. Interpretation guidelines:
- Internal Locus of Control (Stronger belief in personal control over events): 0 – 11
- External Locus of Control (Stronger belief that fate, luck, or powerful others control events): 12 – 23
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of 0.70.
Administration
The scale is self-administered and typically takes approximately 15 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
