A new Work In Progress (WIP) questionnaire effectively measures commitment in individuals with low back pain (LBP). This validated tool shows good psychometric properties for clinical and research use.
Area of Science:
- Rehabilitation Medicine
- Psychology
- Health Sciences
Background:
- Growing evidence supports Commitment Therapy for low back pain (LBP).
- A validated self-report questionnaire is needed to assess commitment in LBP patients.
- Existing tools lack focus on recommended actions and core outcome domains.
Purpose of the Study:
- To develop and psychometrically validate the Work In Progress (WIP) questionnaire.
- To create a tool for evaluating commitment in people with LBP.
- To align assessment with evidenced-based treatment options.
Main Methods:
- Item generation and selection for the WIP questionnaire.
- Assessed face validity, appropriateness, acceptability, and feasibility.
- Conducted psychometric testing including factor analysis, reliability (Cronbach's alpha, ICC), and construct validity (correlation with PCS, ODI, NRS).
Main Results:
- The WIP questionnaire was successfully developed and demonstrated satisfactory validity and feasibility.
- Factor analysis yielded a 10-item, two-factor solution explaining 57% of variance.
- Internal consistency (α=0.70-0.85) and test-retest reliability (ICC=0.91-0.94) were good to excellent.
- Construct validity was confirmed with ≥75% of hypotheses met.
Conclusions:
- The WIP questionnaire is a reliable and valid self-report measure for commitment in LBP patients.
- It possesses satisfactory psychometric properties suitable for clinical and research applications.
- This tool contributes to the bio-psychosocial approach for managing low back pain.
