Scale Overview
The Stop and Start Control Scale – SSCS was developed by De Boer, B. J., Van Hooft, E. A. J., & Bakker, A. B. (2011). It is designed to measure Self-control. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 17 items organized into 2 factors/subscales: Stop Control, Start Control.
| Factor / Subscale |
Items |
N |
| Stop Control |
1,2,3,4,5,6,7,8,9 |

| Start Control |
10,11,12,13,14,15,16,17 |

Response Format
Respondents rate each item using a 7-point Likert scale (1 = Strongly Disagree to 7 = Strongly Agree).
The scale includes 6 reverse-scored items to reduce acquiescence bias.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 17 to 119. Interpretation guidelines:
- Low Self-Control: 17 – 51
- Moderate Self-Control: 52 – 85
- High Self-Control: 86 – 119
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Stop control: alpha = 0.73, Start control: alpha = 0.72.
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.
