Treatment Self-Regulation Questionnaire – Diabetes Version (TSRQ-Diabetes)
Measures the degree to which a patient's motivation for diabetes self-care behaviors is autonomous versus controlled.
Scale Development & Technical Details
Scale Overview
The Treatment Self-Regulation Questionnaire – Diabetes Version (TSRQ-Diabetes) was developed by Williams, G. C., Grow, V. M., Freedman, Z. R., Ryan, R. M., & Deci, E. L. (1996). It is designed to measure Autonomous and Controlled Motivation. The scale is intended for use with Patients with diabetes.
Scale Structure
This instrument consists of 19 items organized into 2 factors/subscales: Autonomous Regulation, Controlled Regulation.
| Factor / Subscale | Items | N |
|---|---|---|
| Autonomous Regulation | 2,3,7,10,13,16,18,19 | 8 |
| Controlled Regulation | 1,4,5,6,8,9,11,12,14,15,17 | 11 |
Response Format
Respondents rate each item using a 7-point Likert scale (1 = Strongly Disagree to 7 = Strongly Agree).
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 1 to 7. Interpretation guidelines:
- Low Regulation: 1 – 3
- Moderate Regulation: 4 – 5
- High Regulation: 6 – 7
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of High internal consistency (typically alpha > 0.80 for both subscales).
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.
