Confidence in providing primary care to patients with low back pain among physiotherapists

Background: Low back pain (LBP) is a common musculoskeletal disorder with distinct clinical features. Direct access to physiotherapy (PT), with physiotherapists (PTs) acting as primary care providers, can improve the management of individuals with LBP. However, clinician confidence may affect their willingness to provide primary care as well as their performance as primary care providers. The objectives of this study were: (1) to develop the Primary Care Confidence Scale (PCCS), and (2) to evaluate PTs’ confidence in managing LBP in primary care. Methods: The PCCS questionnaire was developed through a seven-stage Delphi process involving experts who modified an existing self-confidence scale. The questionnaire was completed by 314 PTs, 140 of whom completed it again after 2 weeks. Structural validity was evaluated using exploratory and confirmatory factor analysis. Reliability was assessed with Cronbach’s alpha for internal consistency and intraclass correlation coefficients (ICC) for test–retest reliability. Spearman tests assessed correlations between background characteristics and PCCS scores. Two independent t-tests estimated the effects of gender and post-graduate education. One-way ANOVA was used to evaluate the impact of the workplace. Results: The PCCS had a multidimensional structure with three factors demonstrating an acceptable model fit and good reliability (α = 0.83, ICC = 0.78). The mean confidence level was 75% (PCCS = 45 ± 6/60), with moderate positive correlations observed between PCCS scores and both age (r = 0.42, p < 0.001) and years of experience (r = 0.33, p < 0.001). PTs working in public or private outpatient clinics had significantly higher scores (PCCS = 45.3 and 47.0, respectively) compared to PTs working in an inpatient hospital or in rehabilitation centers (PCCS = 40.6 and 40.3, respectively, p < 0.009). Conclusions: The newly developed PCCS demonstrated adequate validity and high reliability, suggesting that it is suitable for measuring confidence in treating patients with LBP in primary care settings. PTs demonstrated confidence levels indicative of their perception to manage patients in primary care. Health policy makers and educators could incorporate the PCCS into training and evaluation programs to assess clinicians' confidence and perceived readiness to treat LBP in primary care.
