Can a training programme in motivational interviewing change musculoskeletal physiotherapists’ practice? The example of low back pain

Abstract

BackgroundLow back pain (LBP) is a leading cause of disability nationally and globally, and forms between 40% and 65% of musculoskeletal physiotherapists' caseloads in the UK. Despite professional expectations to deliver person-centred practice, a biomedical and practitioner-centred perspective continues to dominate within physiotherapy. Many physiotherapists lack the knowledge and skills to deliver psychologically informed practice, which for persistent LBP requires consideration of the needs, preferences and values of the patient. Motivational interviewing (MI) has been recommended as a psychologically informed approach for physiotherapists working with persistent LBP patients, although little research has been carried out into its use. AimThis study aims to investigate the effects of MI training on physiotherapists' beliefs, attitudes and practice in relation to persistent LBP. MethodsA convergent parallel mixed methods study was undertaken. Volunteer musculoskeletal physiotherapists (n=16) were recruited from two musculoskeletal physiotherapy departments within a Community NHS Trust in greater London and allocated to either a MI training Group A (n=10) or a comparison Group B (n=6). The MI training group received an initial two-day MI course followed up by monthly supervision sessions delivered in the workplace. Outcomes were measured pretraining (baseline) then at three and six months later for both groups. Beliefs and attitudes and to persistent low back pain were measured using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) and the Health Care Providers Pain and Impairment Relationship Scale (HC-PAIRS). Self-reported proficiency, confidence and intention to use MI were measured using visual analogues scales (VAS). The Motivational Interviewing Training Integrity scale (MITI) generated global ratings and behaviour counts from audio-recordings of initial consultations with persistent LBP patients. The implementation and impact of MI in practice was explored through semi-structured interviews with Group A physiotherapists only at six months.
