The development, validation, and psychometric properties of the Wake Forest Physician Trust Scale (WFPTS)-equivalent instrument for Chinese patients were investigated.
We approached 3442 randomly selected outpatients at 3 Shanghai (China) general hospitals, treated ≥2 times per year by the same physician, for participation between November 2008 and December 2008. A Chinese version of the WFPTS (C-WFPTS) was prepared and administered to eligible and consenting patients, and subjected to validity assessment using 5 patient behaviors: (1) recommendation of the physician; (2) occurrence of dispute; (3) seeking a second opinion; (4) treatment adherence; and (5) consideration of switching physicians.
A total of 352 (M: F, 149: 203; mean age, 40.67±17.31 years; age range, 14-94 years) consenting and eligible patients were included in the analysis. The unidimensionality and internal consistency of C-WFPTS was confirmed (Cronbach's α=0.833). Physician trust correlated significantly with physician satisfaction (r=0.73, P<0.001) and all 5 behaviors (1: r=0.453, 2: r=0.209, 3: r=0.406, 4: r=0.444, 5: r=0.471; P<0.001 for all), indicating validity and predictive validity, respectively. Patient trust increased significantly with increasing age and physician visits (P>0.05), but was not related to gender, birthplace, or insurance type.
C-WFPTS has good psychometric properties, reliability, and validity for the evaluation of patient trust in the patient-physician relationship, and thereby provides an essential tool for the characterization of patient-physician relationships in China, which is necessary for healthcare reform.
对中国患者而言，研究了与维克森林医生信任量表（WFPTS）等效的工具的开发、验证及其心理测量特性。
2008年11月至2008年12月期间，我们在中国上海的3家综合医院随机抽取了3442名门诊患者，这些患者每年接受同一位医生治疗≥2次，邀请他们参与研究。编制了中文版的WFPTS（C-WFPTS），并施用于符合条件且同意参与的患者，使用5种患者行为进行效度评估：（1）对医生的推荐；（2）纠纷的发生；（3）寻求第二种意见；（4）治疗依从性；（5）考虑更换医生。
共有352名（男：女，149：203；平均年龄，40.67±17.31岁；年龄范围，14 - 94岁）符合条件且同意参与的患者纳入分析。证实了C-WFPTS的单维度性和内部一致性（Cronbach's α = 0.833）。医生信任与医生满意度显著相关（r = 0.73，P < 0.001），且与所有5种行为均显著相关（1：r = 0.453，2：r = 0.209，3：r = 0.406，4：r = 0.444，5：r = 0.471；所有P < 0.001），分别表明了效度和预测效度。患者信任随年龄增长和看诊次数增加而显著增加（P > 0.05），但与性别、出生地或保险类型无关。
C-WFPTS在评估患者 - 医生关系中患者信任方面具有良好的心理测量特性、可靠性和效度，从而为中国患者 - 医生关系的特征描述提供了一个重要工具，这对医疗改革是必要的。
