Measures multidimensional work commitment across four distinct facets: occupational commitment, job involvement, value of work, and organizational commitment.
Scale Development & Technical Details
Scale Overview
The Work Commitment Index – WCI was developed by Gary J. Blau (1993). It is designed to measure Work Commitment. The scale is intended for use with Working adults.
Scale Structure
This instrument consists of 31 items organized into 4 factors/subscales: Occupational Commitment, Job Involvement, Value of Work, Organizational Commitment.
| Factor / Subscale | Items | N |
|---|---|---|
| Occupational Commitment | 1,2,3,4,5,6,7,8,9,10,11 | 11 |
| Job Involvement | 12,13,14,15,16,17,18 | 7 |
| Value of Work | 19,20,21,22,23,24,25 | 7 |
| Organizational Commitment | 26,27,28,29,30,31 | 6 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Strongly Disagree, 2 = Moderately Disagree, 3 = Slightly Disagree, 4 = Slightly Agree, 5 = Moderately Agree, 6 = Strongly Agree.
The scale includes 10 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 31 to 186. Interpretation guidelines:
- Low Work Commitment: 31 – 82
- Moderate Work Commitment: 83 – 134
- High Work Commitment: 135 – 186
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Alpha: 0.91 (Occupational Commitment), 0.83 (Job Involvement), 0.81 (Value of Work), 0.82 (Organizational Commitment).
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.
