Development of clinical reasoning is an essential aspect in musculoskeletal physiotherapy practice that is linked to better outcomes. The measurement of clinical reasoning has placed an emphasis on diagnostic reasoning using different types of examinations. The Diagnostic Thinking Inventory (DTI) is a self-assessment tool developed to measure two aspects of diagnostic reasoning: flexibility in thinking (FT) and structure in memory (SM). DTI is valid and reliable that has been used extensively in medical field.
To investigate the validity and reliability of DTI in musculoskeletal physiotherapy practice.
Two groups of musculoskeletal physiotherapists completed DTI. Expert musculoskeletal physiotherapists assessed face and content validity. Data from the second group of musculoskeletal physiotherapists were used to assess test-retest reliability. Internal consistency was calculated using Cronbach's alpha. Construct validity was assessed by comparing both groups. Data were analyzed using the IBM SPSS statistics 25.0 version.
The experts agreed that DTI measures diagnostic reasoning. For test-retest reliability, average intraclass correlation coefficient was 0.91, 0.92 and 0.90 (p < 0.001) for DTI, FT and SM scores, respectively. Cronbach's alpha was 0.909, 0.919 and 0.897 (p < 0.001) for DTI, FT and SM, respectively. The independent samples t-test demonstrated that the experts group achieved higher and statistically significant score (p < 0.001).
DTI is valid and reliable in measuring diagnostic reasoning in the context of musculoskeletal physiotherapy practice. It can be used to assess the impact of continuing education on musculoskeletal physiotherapists' diagnostic reasoning.
临床推理能力的发展是肌肉骨骼物理治疗实践中的一个重要方面，它与更好的治疗效果有关。临床推理的测量侧重于使用不同类型的检查进行诊断推理。诊断思维量表（DTI）是一种自我评估工具，用于衡量诊断推理的两个方面：思维灵活性（FT）和记忆结构（SM）。DTI 在医学领域得到了广泛的验证和使用，具有有效性和可靠性。
调查 DTI 在肌肉骨骼物理治疗实践中的有效性和可靠性。
两组肌肉骨骼物理治疗师完成了 DTI。专家肌肉骨骼物理治疗师评估了其表面效度和内容效度。第二组肌肉骨骼物理治疗师的数据用于评估测试-重测信度。使用 Cronbach 的 alpha 计算内部一致性。通过比较两组来评估结构效度。使用 IBM SPSS statistics 25.0 版本进行数据分析。
专家们一致认为 DTI 测量诊断推理。对于测试-重测信度，DTI、FT 和 SM 得分的平均组内相关系数分别为 0.91、0.92 和 0.90（p<0.001）。DTI、FT 和 SM 的 Cronbach 的 alpha 分别为 0.909、0.919 和 0.897（p<0.001）。独立样本 t 检验表明，专家组的得分更高且具有统计学意义（p<0.001）。
DTI 在测量肌肉骨骼物理治疗实践中的诊断推理方面是有效和可靠的。它可用于评估继续教育对肌肉骨骼物理治疗师诊断推理的影响。
