Full description
Back Beliefs Questionnaire was translated and culturally adapted into Turkish regarding to the published guidelines. This observational cross-sectional study was performed with 110 chronic low back pain patients. All participants were asked to complete Back Beliefs Questionnaire and also fill the socio-demographic data form and evaluation tools (Numeric rating scale-pain, Oswestry Disability Index, Fear Avoidance Beliefs Questionnaire, Hospital Anxiety and Depression Scale). Internal consistency was evaluated with Cronbach's alfa coefficient. Intraclass correlation coefficient was used to assess test-retest reliability. Structural validity was assessed by correlations with other tools.
Back Beliefs Questionnaire had a good internal consistency (Cronbach alfa= 0.79) and an excellent test-retest reliability (Intraclass correlation coefficient = 0.84). A moderate correlation was determined between Back Beliefs Questionnaire and Fear Avoidance Beliefs Questionnaire. Correlations with Numeric rating scale-pain, Oswestry Disability Index, Hospital Anxiety and Depression Scale were fair.
Turkish version of Back Beliefs Questionnaire is a valid and reliable questionnaire that can be used to evaluate beliefs about pain in patients with chronic low back pain.
