Gibbs MT, et al. - A cross-sectional survey was performed to evaluate the impact of biomedical and biopsychosocial attitudes and beliefs toward chronic low back pain (CLBP) on clinical decision making in exercise-based practitioners. Using the pain attitudes and beliefs scale for physiotherapists, seventy-five accredited exercise physiologists (AEPs), and 75 physiotherapists were surveyed, which consists of both a biomedical and biopsychosocial subscale. Using two patient vignettes, clinical decision making was evaluated. This study’s findings demonstrated that the biomedical attitudes and beliefs regarding CLBP influence clinical decision making in exercise-based practitioners, regardless of profession. According to the results, AEPs recorded higher biomedical scores, implying a more frequent choice of conservative care. Therefore, individuals may receive inconsistent care and advice from practitioners in the same field. Based on clinical practice guidelines and the positive relationships on clinical decision making of the biopsychosocial model, it is important to acknowledge how best to provide exercise-based practitioners with education on how to use a biopsychosocial approach to CLBP.
