Cross-cultural adaptation, validation and psychometric evaluation of the attitudes to back pain scale in musculoskeletal practitioners - Hebrew version.

BACKGROUND

Research suggests that clinician's attitudes and beliefs towards low back pain (LBP) management may affect their patients' treatment course and outcomes. Attitudes to Back pain Scale in musculoskeletal practitioners (ABS-mp) is a questionnaire developed to assess musculoskeletal clinicians' attitudes and beliefs regarding LBP.

OBJECTIVE

This study aimed to translate, culturally adapt, and evaluate the psychometric properties of the Hebrew version of the ABS-mp questionnaire.

DESIGN

Cross-sectional study with nested prospective sub-sample.

METHODS

The translation was performed in several steps following the cross-cultural adaptation process. Test-retest and internal consistency reliability of the scales were evaluated along with convergent validity exploration between the ABS-mp and the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS). A convenience sample of 177 physical therapists were requested to participate in the study, out of which 132 have completed the survey, providing a 74% participation rate.

RESULTS

The forward-backward translation process revealed minor discrepancies that were addressed by the expert panel. The test-retest reliability of the Hebrew ABS-mp was excellent (ICC = 0.906). Five items were found to be irrelevant for the Israeli physiotherapy health settings and were omitted. For internal consistency, the average inter-item correlation reached appropriate values for the Psychological, Biomedical, Re-activation, and Limitation on Sessions subscales (0.437, 0.265, 0.341, 0.197, respectively). For convergent validity, the ABS-mp's Biomedical subscale and the HC-PAIRS's total score were moderately correlated (0.535).

CONCLUSIONS

The Hebrew version of the ABS-mp has been validated and has demonstrated excellent test-retest reliability, good convergent validity and acceptable internal consistency.
