The Curtin Back Screening Questionnaire (CBSQ) effectively identifies and assesses disability in occupational low back pain (LBP). This validated tool aids practitioners in early recognition and management planning for LBP patients.
Area of Science:
- Occupational Health
- Rehabilitation Medicine
- Psychometrics
Background:
- Occupational low back pain (LBP) presents diverse, incapacitating symptoms challenging systematic clinical identification.
- Effective case-finding and assessment tools are crucial for early disability recognition and management planning in LBP.
- Existing literature lacked a suitable questionnaire for clinical LBP disability screening.
Purpose of the Study:
- To present the development and validation of the Curtin Back Screening Questionnaire (CBSQ).
- To establish the CBSQ as a discriminative screening instrument for occupational LBP disability.
- To provide a tool for early recognition and management planning of LBP.
Main Methods:
- Questionnaire development followed Kirschner and Guyatt (1985) principles.
- Validation involved a multiple-group repeated-measures design with 150 subjects.
- Regression analysis selected 8 screening questions from a 79-item instrument based on perceived health status.
Main Results:
- The CBSQ effectively discriminates between varying degrees of LBP disability.
- It demonstrates good correlation with the Sickness Impact Profile (SIP).
- Test-retest reliability is high (0.98), with favorable receiver-operating characteristics compared to SIP.
Conclusions:
- The CBSQ is a validated, reliable screening tool for occupational LBP.
- Its screening score serves as an index of severity, correlating with work incapacity.
- The CBSQ facilitates efficient assessment and management planning for LBP patients.
