Scale Development & Technical Details
Scale Overview
The Extent of Computer Use Scale was developed by J. W. Medcof (1996). It is designed to measure Computer use extent and cognitive demand. The scale is intended for use with Working adults.
Scale Structure
This instrument consists of 12 items organized into 4 factors/subscales: Extent of Computer Use, Low Cognitive Demand, Medium Cognitive Demand, High Cognitive Demand.
| Factor / Subscale | Items | N |
|---|---|---|
| Extent of Computer Use | 1,2,3,4 | 4 |
| Low Cognitive Demand | 5,6,7 | 3 |
| Medium Cognitive Demand | 8,9 | 2 |
| High Cognitive Demand | 10,11 | 2 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Rarely (for Item 4), 5 = Always (for Item 4).
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 0.77.
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.
