Outcome Measure
Pain Self-Efficacy Questionnaire
What it measures?
- The beliefs held by people experiencing chronic pain that they can carry out certain activities even when experiencing pain.
Who is it for?
Adults aged 18 years +
Instrument Quality
- The PSEQ is widely used and recommended for use in multidisciplinary pain programs. A systematic review confirmed that the PSEQ possesses good construct validity and correlates negatively with measures of disability, pain interference, anxiety, depression and catastrophising (Dube, Roy & Langevin, 2021).
Structure
- 10 items
- 7-point Likert scale
- Respondents are asked to read 10 statements and rate how confident that they are in being able to do the activity (0 = "Not at all confident"; 6 = "Completely confident") reflected in each statement (e.g. “I can enjoy things despite pain”)
Scoring instructions
Sum all item responses to derive a full-scale score
| Subscale | Item number |
|---|---|
Full-scale (PSEQ) |
1,2,3,4,5,6,7,8,9,10 |
Score Interpretation
What higher scores mean?
- Higher scores are desirable and indicate higher levels of confidence to perform activities despite pain (i.e. pain self-efficacy)
How to assess symptom severity & change?
| Description | Score Range | |
|---|---|---|
| Severe | 0 | |
| Moderate | 20 | |
| Mild | 31 | |
| Minimal | 41 |

Reliable change and clinically significant improvement
A systematic review evaluated four studies and calculated a weighted mean for the Standard Error of Measurement (Dubé, Langevin & Roy, 2021). The minimal detectable change with a 95% confidence interval was 11.52 out of 60 points (range 3.41-11.52). The reference manual for the Electronic Persistent Pain Outcomes Collaboration (ePPOC) recommends that clinically significant change is indicated where there is a change of 7 or more points, coupled with a move to a different level of impairment.
