目标.进一步验证和评估医生信任量表的信度和效度。一项为期6个月的前瞻性研究招募了来自20个社区初级保健机构的连续性成年患者（n = 414）。在入组时，受试者完成了Ii项医生信任量表加上人口统计学指标、护理偏好和对医生护理的满意度。在6个月时测量连续性、护理满意度和自我报告的治疗依从性。信度，结构效度和预测效度进行了评估，采用相关系数和方差分析技术。医生信任量表内部一致性较高（Cronbach's alpha =.89）和良好的1个月重测信度（组内相关系数= 0.77），正如预期的那样，信任随着关系的长度而增加，并且在主动选择医生的患者中更高，他们更喜欢医生的参与，并且期望他们的医生照顾他们的问题的更大比例（所有协会P <0.001）。基线信任预测与医生的连续性，自我报告的药物依从性，以及在调整性别，年龄，教育，关系长度，医生的主动选择和护理偏好后6个月的满意度。在对医生护理的基线满意度进行额外调整后，信任仍然是连续性，依从性和满意度的重要预测因素。医师信任量表具有良好的心理测量学特征，并具有结构效度和预测效度。它似乎与患者对医生的满意度有关，但仍与患者对医生的满意度不同，因此，它为评估患者-医生关系的质量提供了一个有价值的额外措施。
OBJECTIVES. TO further validate and assess the reliability and validity of the Trust in Physician Scale.METHODS. Consecutive adult patients (n = 414) from 20 community-based, primary care practices were enrolled in a prospective, 6-month study. At enrollment, subjects completed the Ii-item Trust in Physician Scale plus measures of demographics, preferences for care, and satisfaction with care received from the physician. Continuity, satisfaction with care, and self-reported adherence to treatment were measured at 6 months. Reliability, construct validity, and predictive validity were assessed using correlation coefficients and analysis of variance techniques.RESULTS. The Trust in Physician Scale showed high internal consistency (Cronbach's alpha = .89) and good 1-month test-retest reliability (intraclass correlation coefficient = .77), As expected, trust increased with the length of the relationship and was higher among patients who actively chose their physician, who preferred more physician involvement, and who expected their physician to care for a larger proportion of their problems (P < 0.001 for all associations). Baseline trust predicted continuity with the physician, self-reported adherence to medication, and satisfaction at 6 months after adjustment for gender, age, education, length of the relationship, active choice of the physician, and preferences for care. After additional adjustment for baseline satisfaction with physician care, trust remained a significant predictor of continuity, adherence, and satisfaction.CONCLUSIONS. The Trust in Physician Scale has desirable psychometric characteristics and demonstrates construct and predictive validity. It appears to be related to, but still distinct from, patient satisfaction with the physician and, thus, provides a valuable additional measure for assessment of the quality of the patient-physician relationship.
