Exploring the utility of the Pain Attitudes and Beliefs Scale with general practitioners and physiotherapists in the context of osteoarthritis: a cross-sectional observational study
Abstract Background Conservative treatments for hip and knee joint osteoarthritis are underused despite the known benefits. Adherence to conservative treatments is poor and affected by people’s health, illness and treatment beliefs. Clinicians’ beliefs can also affect the advice and education given to patients. Few studies have explored general practitioners’ (GPs; primary care physicians) and physiotherapists’ osteoarthritis-related health, illness and treatment beliefs. In addition, limited questionnaires are available to explore this phenomenon. This study aimed to identify if GPs and physiotherapists had beliefs about osteoarthritis that fit better with biomedical or biopsychosocial models, and explore the utility of the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) adapted for osteoarthritis. Methods This study used a cross-sectional observational design. Data were collected anonymously from GPs and physiotherapists using an online survey. The survey included a study-specific demographic and occupational characteristics questionnaire and the PABS-PT questionnaire adapted for osteoarthritis. All data were analysed using descriptive statistics. PABS-PT data also underwent principal factor analysis. Results In total, 295 clinicians (87 GPs, 208 physiotherapists) participated in this study. The principal factor analysis identified two factors or subscales (biomedical and behavioural), with Cronbach’s alphas of 0.84 and 0.44, respectively. Participants scored higher on the behavioural (3.85) than the biomedical (2.78) beliefs subscale. Conclusions The results suggest clinicians’ osteoarthritis beliefs are broadly more behavioural (biopsychosocial) than biomedical in orientation. However, the poor internal consistency of the behavioural subscale suggests the PABS-PT is not suitable for adaptation for osteoarthritis.
