Turkish version of health care providers' pain and impairment relationship scale: Reliability and validity

To develop the Turkish version of the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS-TR) by conducting the linguistic and cultural adaptation and to examine the psychometric properties and reliability of the adapted version.

A double back-translation procedure was used to translate the questionnaire. Participants received an online survey package with the HC-PAIRS-TR, the Turkish version of Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT-TR), and Turkish Version of the Tampa Scale for Kinesiophobia (TSK-TR). Cronbach's alpha coefficient and item analysis were used to evaluate internal consistency. Intraclass correlation coefficient (ICC) was used to determine the test-retest reliability. Confirmatory factor analysis (CFA) and Rasch Analysis were performed.

The study was conducted with 153 physiotherapists practicing in Turkey. Cronbach's alpha was 0.81. Test-retest reliability was high (ICC = 0.85, p < 0.001), the standard error of measurement was 4.96 (0.94% of mean), and minimal detectable change was 13.75 (26.06% of mean). HC-PAIRS-TR scores correlated significantly with scores for the biomedical factor of the PABS-PT-TR (r = 0.52, p = 0.00), biopsychosocial factor of PABS-PT-TR (r = 0.32, p = 0.00), and TSK-TR (r = 0.52, p = 0.00). According to CFA and Rasch Analysis, the 12 items version of HC-PAIRS-TR fits the one-factor model excellently.

The HC-PAIRS-TR appears to be a reliable and valid questionnaire to measure Turkish physiotherapists' beliefs and attitudes about the relationship between low back pain and impairment. Future studies might be planned to validate this questionnaire for other health care providers.
