目的：开发并验证一个简短的工具“患者与医生互动感知功效问卷 (PEPPI)”，以衡量老年患者从医生那里获取医疗信息和关注其医疗问题的自我效能。设计：两次连续的验证调查。地点：加利福尼亚州洛杉矶县的 11 个高级多功能中心。人口：163 名社区居住老年人的便利样本（调查 1：n） = 59，平均年龄 = 77.1 岁，76.3% 为女性；调查 2：n = 104，平均年龄 = 77.4 岁，57.7% 女性结果：完整的 10 项和 5 项简短形式的 PEPPI 证明 Cronbach 的 alpha 值分别为 0.91 和 0.83。 PEPPI 表现出所假设的区分效度和收敛效度，与回避应对 (r = -.27, P = .001) 呈负相关，与主动应对 (r = .17, P = .03) 呈正相关，并与患者对医生人际方式 (r = .49, P < .0001) 和沟通 (r = .51, P < .0001) 的满意度呈正相关（值来自总体）样本）。此外，在第二次调查中，PEPPI 与自我报告的健康（r = .42，P < .0001）、教育（r = .24，P = .01）和自我掌控（r = .29，P = .01）呈正相关，与限制活动天数呈负相关（r = -.25，P = .01）。 PEPPI-5 在幅度、方向和统计显着性方面表现出相似的相关性。结论：无论是 5 项还是 10 项版本，PEPPI 都是衡量老年患者在与医生互动时感知自我效能的有效且可靠的指标。该工具可能有助于衡量赋权干预措施的影响，以提高老年患者在获得所需医疗保健方面的个人有效性感。
OBJECTIVE: To develop and validate a brief instrument the Perceived Efficacy in Patient-Physician Interactions Questionnaire (PEPPI) - to measure older patients' self-efficacy in obtaining medical information and attention to their medical concerns from physicians.DESIGN: Two consecutive validation surveys.SETTING: Eleven senior multipurpose centers in Los Angeles County California.POPULATION: A convenience sample of 163 community dwelling older persons (Survey 1: n = 59, mean age = 77.1 years, 76.3% female; Survey 2: n = 104, mean age = 77.4 years, 57.7% female).MEASURES: The 10-item PEPPI, subscales of the Patient Satisfaction Questionnaire, the Medical Outcomes Study (MOS) Coping Scale, the Mastery Scale, and global self-reported health and restricted activity days items.RESULTS: The full 10-item and a 5-item short form of PEPPI demonstrated Cronbach's alphas of 0.91 and 0.83, respectively. PEPPI demonstrated discriminant and convergent validity as hypothesized, correlating negatively with avoidant coping (r = -.27, P = .001) and positively with active coping (r = .17, P = .03) and with patient satisfaction with physician interpersonal manner (r = .49, P < .0001) and communication (r = .51, P < .0001) (values from the overall sample). Further, in the second survey, PEPPI correlated positively with self-reported health (r = .42, P < .0001), education (r = .24, P = .01) and self-mastery (r = .29, P = .01) and negatively with restricted activity days (r = -.25, P = .01). PEPPI-5 demonstrated correlations similar in magnitude, direction, and statistical significance.CONCLUSION: In either the 5- or 10-item version, PEPPI is a valid and reliable measure of older patients' perceived self-efficacy in interacting with physicians. This instrument may be useful in measuring the impact of empowerment interventions to increase older patients' personal sense of effectiveness in obtaining needed health care.
