Scale Development & Technical Details
Scale Overview
The Extent of Computer Use Scale was developed by Medcof, J. W. (1996). It is designed to measure Extent and cognitive demand of computer use at work. The scale is intended for use with Working adults / employees.
Scale Structure
This instrument consists of 12 items organized into 4 factors/subscales: Extent of Computer Use, Low Cognitive Demand Use, Medium Cognitive Demand Use, High Cognitive Demand Use.
| Factor / Subscale | Items | N |
|---|---|---|
| Extent of Computer Use | 1,2,3,4 | 4 |
| Low Cognitive Demand Use | 5,6,7 | 3 |
| Medium Cognitive Demand Use | 8,9 | 2 |
| High Cognitive Demand Use | 10,11 | 2 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Rarely, 2 = Seldom, 3 = Occasionally, 4 = Frequently, 5 = Always.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of alpha = .77.
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.
