This study aimed to investigate the impact of a brief psychologically informed physiotherapy training (PIPT) course on physiotherapists' attitudes and beliefs towards working with people with chronic pain. Specifically, the training aimed to help the participants better recognise the role of psychosocial factors in chronic pain and to better target the key processes of the psychological flexibility (PF) model in their treatment interactions. A total of 26 physiotherapists working in an outpatient musculoskeletal (MSK) department participated in the 7-hour training session. A total of 25 participants completed self-report questionnaires on attitudes and beliefs, burnout and PF-relevant processes pre- and post-training. The pre- and post-measures were completed on the day of training. PIPT was associated with significant changes in the expected direction in physiotherapists' attitudes towards treatment of people with chronic pain, including a moderate effect size on the Health Care Provider-Pain and Impairment Relationship Scale (HC-PAIRS) (decreased biomedical scores) and a large effect size on the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) (increased biopsychosocial scores and decreased biomedical scores). In conclusion, brief PIPT could help physiotherapists working in non-specialist centres with complex patients, many of whom present with significant emotional distress and pain-related disability. Further research is required to determine whether the changes in attitudes detected in this study translate into clinical practice and whether changes are maintained over a follow-up period.

The application of the Economy of Action hypothesis and the notion of spatial perceptual scaling as a means to assess and treat the experience of chronic pain are not supported by the results of this study.
