Interprofessional collaboration is recommended in health systems everywhere, but research on its measurement is needed. This psychometric study assessed the construct validity, internal consistency, and test-retest reliability of the Intensity of Interprofessional Practices Questionnaire for Private-Sector Physiotherapists (IIPQ-PT). A random sample of 303 physiotherapists (PTs) completed the 12-item questionnaire, and a subsample of 103 completed it a second time 2 weeks later. Exploratory factor analyses revealed a one-factor solution for the instrument. IIPQ-PT scores showed respectively fair and moderate relationships with the percentage of low back pain clients for whom PTs reported interactions with other professionals (0.30; 95% CI 0.19-0.40; p<0.001) and perceived degree of interactions (0.58; 95% CI 0.50-0.65; p<0.001). The IIPQ-PT had high internal consistency (Cronbach's a= 0.86; 95% CI 0.83-0.88) and good test-retest reliability (ICC=0.69; 95% CI 0.57-0.78). The minimum detectable difference for a 95% CI was 2.52. Although further study of this instrument is warranted, our results are promising for its future use. The IIPQ-PT may prove useful to evaluate the effectiveness of interventions aiming to improve interprofessional practices and to measure the effects of such practices on service users, providers, and the health system.
各地卫生系统都建议开展跨专业协作，但仍需要对其进行测量的研究。这项心理测量学研究评估了《私营部门物理治疗师跨专业实践强度问卷》（IIPQ-PT）的结构效度、内部一致性和重测信度。303名物理治疗师的随机样本完成了这份包含12个条目的问卷，103名的子样本在两周后再次完成了问卷。探索性因素分析揭示了该工具的单因素解决方案。IIPQ-PT得分与物理治疗师报告与其他专业人员互动的腰痛患者百分比（0.30；95%可信区间0.19 - 0.40；p<0.001）以及感知到的互动程度（0.58；95%可信区间0.50 - 0.65；p<0.001）分别呈现出中等和较高的相关性。IIPQ-PT具有较高的内部一致性（克朗巴赫α系数=0.86；95%可信区间0.83 - 0.88）和良好的重测信度（组内相关系数ICC=0.69；95%可信区间0.57 - 0.78）。95%可信区间的最小可检测差异为2.52。尽管有必要对该工具进行进一步研究，但我们的结果对其未来应用很有前景。IIPQ-PT可能有助于评估旨在改善跨专业实践的干预措施的有效性，并衡量此类实践对服务使用者、提供者和卫生系统的影响。
