Awareness Questionnaire – AQ
Measures impairments in self-awareness of motor/sensory, cognitive, and behavioral/affective functioning after brain injury.
Scale Development & Technical Details
Scale Overview
The Awareness Questionnaire – AQ was developed by Sherer M. (1998). It is designed to measure Self-awareness of deficits after brain injury. The scale is intended for use with Adults with traumatic brain injury or stroke.
Scale Structure
This instrument consists of 17 items organized into 3 factors/subscales: Motor/Sensory, Cognitive, Behavioral/Affective.
| Factor / Subscale | Items | N |
|---|---|---|
| Motor/Sensory | 1,2,3,4,5 | 5 |
| Cognitive | 6,7,8,9,10,14,15 | 7 |
| Behavioral/Affective | 11,12,13,16,17 | 5 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Much worse, 2 = A little worse, 3 = About the same, 4 = A little better, 5 = Much better.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 17 to 85. Interpretation guidelines:
- Perceived decline in functioning compared to pre-injury: 17 – 50
- Perceived functioning is about the same as pre-injury: 51 – 51
- Perceived improvement in functioning compared to pre-injury: 52 – 85
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of High internal consistency (Cronbach's alpha > 0.80).
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.
