Work Commitment Index – WCI
Measures an individual's level of commitment across four distinct work-related facets: occupation, job, work values, and organization.
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 / employees.
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 – 93
- Moderate Work Commitment: 94 – 155
- High Work Commitment: 156 – 186
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Cronbach's 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 8 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
