A brief and psychometrically sound scale to measure patients' overall satisfaction with their primary care physicians would be useful in studies where a longer instrument is impractical. The purpose of this study was to develop and examine the psychometrics of a brief instrument to measure patients' overall satisfaction with their primary care physicians.
Research participants included 535 outpatients (between 18--75 years old, 66% female) who completed a mailed survey that included 10 items for measuring overall satisfaction with their primary care physician who was named on the survey. Patients were also asked about their perceptions of physician empathy, preventive tests recommended by the physician (colonoscopy, mammogram, and prostate-specific antigen (PSA) for age and gender appropriate patients) and demographic information.
Factor analysis of the patient satisfaction items resulted in one prominent component. Corrected item-total score correlations of the patient satisfaction scale ranged from 0.85 to 0.96; correlation between patient satisfaction scores and patient perception of physician empathy was 0.93, and correlation with recommending the physician to family and friends was 0.92. Criterion-related validity coefficients were mostly in the 0.80s and 0.90s. Patient satisfaction scores were significantly higher for those whose physicians recommended preventive tests (colonoscopy, mammogram, and PSA-compliance rates >.80). Cronbach's coefficient alpha for patient satisfaction scale was 0.98.
Empirical evidence supported the validity and reliability of a brief patient satisfaction scale that has utility in the assessments of educational programs aimed at improving patient satisfaction, medical services, and patient outcomes in primary care settings.
在研究中，若使用较长的量表不切实际，那么一个简短且心理测量学上可靠的量表来衡量患者对其初级保健医生的总体满意度将会很有用。本研究的目的是开发并检验一个简短量表的心理测量学特性，该量表用于测量患者对其初级保健医生的总体满意度。
研究参与者包括535名门诊患者（年龄在18至75岁之间，66%为女性），他们完成了一项邮寄调查，该调查包含10个项目，用于衡量他们对调查中所提及的初级保健医生的总体满意度。患者还被问及他们对医生同理心的看法、医生推荐的预防性检查（针对年龄和性别合适的患者进行结肠镜检查、乳房X光检查和前列腺特异性抗原（PSA）检测）以及人口统计学信息。
对患者满意度项目进行因子分析得出一个显著的成分。患者满意度量表的校正后的项目总分相关性在0.85至0.96之间；患者满意度得分与患者对医生同理心的感知之间的相关性为0.93，与向家人和朋友推荐该医生的相关性为0.92。与标准相关的效度系数大多在0.80和0.90之间。对于那些医生推荐预防性检查（结肠镜检查、乳房X光检查和PSA - 依从率>.80）的患者，其满意度得分显著更高。患者满意度量表的克朗巴哈系数α为0.98。
实证证据支持了一个简短的患者满意度量表的有效性和可靠性，该量表在评估旨在提高初级保健环境中的患者满意度、医疗服务和患者结局的教育项目中具有实用价值。
