Attentional Resource Allocation Scale – ARAS
A 15-item self-report scale designed to assess the attention-modifying trait constructs of absorption and dissociation.
Scale Development & Technical Details
Scale Overview
The Attentional Resource Allocation Scale – ARAS was developed by Carleton, R. N., Abrams, M. P., & Asmundson, G. J. G. (2010). It is designed to measure Absorption and Dissociation. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 15 items organized into 3 factors/subscales: Imaginative Involvement, Dissociative Amnesia, Attentional Dissociation.
| Factor / Subscale | Items | N |
|---|---|---|
| Imaginative Involvement | 1,3,8,9,10,12 | 6 |
| Dissociative Amnesia | 2,5,7,11,13 | 5 |
| Attentional Dissociation | 4,6,14,15 | 4 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 0 = Never, 1 = Rarely, 2 = Sometimes, 3 = Often, 4 = Always.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 0 to 60. Interpretation guidelines:
- Low: 0 – 15
- Moderate: 16 – 30
- High: 31 – 45
- Very High: 46 – 60
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of α = .85 (undergraduate), α = .91 (community).
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.
