Background. In orthopedics, there is no instrument specifically designed to assess patients' expectations of their final surgery outcome in general trauma populations. We developed the Trauma Expectation Factor Trauma Outcome Measure (TEFTOM) to investigate the fulfilment of patients' expectations one year after surgery as a measure of general trauma surgical outcomes. The aim of this paper was to assess the psychometric characteristics of this new general trauma outcome measure. Methods. The questionnaire was tested in 201 ankle and distal tibia fracture patients scheduled for surgery. Patients were followed up for twelve months. The TEFTOM questionnaire was evaluated for its criterion validity, internal consistency, reproducibility, and responsiveness. Results. TOM showed good criterion validity against the American Academy of Orthopaedic Surgeons Foot and Ankle Scale (Pearson's correlation coefficient = 0.69-0.77). Internal consistency was acceptable for TEF (Cronbach's alpha = 0.65-0.76) and excellent for TOM (Cronbach's alpha = 0.76-0.85). Reproducibility was moderate to very good (intraclass coefficient correlation (ICC) ≥0.67) for TEF and very good (ICC ≥0.92) for TOM. TOM also proved to be responsive to changes in patients' condition over time (Wald test; P < 0.001). Conclusions. TEFTOM is a promising tool for measuring general trauma outcomes in terms of patients' expectation fulfilment that proved to be valid, internally consistent, reproducible, and responsive to change.
背景。在骨科领域，尚无专门设计用于评估普通创伤人群对最终手术结果期望的工具。我们开发了创伤期望因子创伤结果测量量表（TEFTOM），以调查患者术后一年期望的实现情况，作为普通创伤手术结果的一项衡量指标。本文旨在评估这一新的普通创伤结果测量量表的心理测量学特征。方法。该问卷在201例计划接受手术的踝关节和胫骨干骺端骨折患者中进行了测试。对患者进行了为期十二个月的随访。对TEFTOM问卷的效标效度、内部一致性、可重复性和反应性进行了评估。结果。与美国矫形外科医师学会足踝量表相比，TOM显示出良好的效标效度（皮尔逊相关系数 = 0.69 - 0.77）。TEF的内部一致性可接受（克朗巴哈系数α = 0.65 - 0.76），TOM的内部一致性极佳（克朗巴哈系数α = 0.76 - 0.85）。TEF的可重复性为中等至非常好（组内相关系数（ICC）≥0.67），TOM的可重复性非常好（ICC≥0.92）。TOM还被证明对患者病情随时间的变化有反应（ Wald检验；P < 0.001）。结论。TEFTOM是一种很有前景的工具，可用于衡量普通创伤结果，即患者期望的实现情况，且已证明其有效、内部一致、可重复且对变化有反应。
