A NEW BIOPSYCHOSOCIAL QUESTIONNAIRE FOR PATIENTS WITH KNEE OSTEOARTHRITIS

Background: OA is a problem that cartilage damage occurs, which leads to stiffness in the joint, pain and functional limitations (1). This problem can also cause psychosocial impact like other chronic diseases (2). As with other rheumatic diseases, this complex picture of inflammation required biopsychosocial approaches and measurement methods for knee OA. Objectives: This study was planned to investigate the validity and reliability of a new biopsychosocial questionnaire which is named Cognitive Exercise Therapy Approach Biopsychosocial Questionnaire (BETY-BQ) in individuals with knee osteoarthritis (OA). Methods: The study included 150 individuals who diagnosed knee osteoarthritis at stage 1 or 2 according to the Kellgren-Lawrence scale. For determining daily living activities; Health Assessment Questionnaire (HAQ), for quality of life Short Form-36 (SF-36) Quality of Life Scale, for anxiety and depression levels; Hospital Anxiety and Depression Scale (HADS), for severity of disease Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and for biopsychosocial evaluation BETY-BQ were used. Results: The correlation between BETY-BQ and other scales was examined by Spearman correlation analysis (r=-0.252, 0.633, p<0,05). Cronbach’s alpha coefficient and item-total correlation were used as reliability methods. Cronbach’s alpha coefficient was examined for the internal consistency of the scale and was found to be 0.887 for the first evaluation, 0.917 for measurements after 1 week and 0.843 for measurements after 3 months. Item total correlation, which was another indicator of reliability, ranged from 0.632 to 0.854 (p<0.05). Table 1.

This result showed that BETY-BQ can be used in clinics to evaluate biopsychosocial involvement in patients with knee OA. REFERENCES: [1]Hunter DJ, Felson DT. Clinical review: osteoarthritis.
