Patient navigation (PN) is a method for addressing racial-ethnic and socioeconomically based disparities in cancer-related care. Patient navigators provide logistic and emotional support to underserved patients to facilitate successful completion of diagnostic and treatment care. Yet, little is known about patient satisfaction with the relationship with a navigator due to a dearth of instruments measuring satisfaction.
The objective of this study was to validate the Patient Satisfaction with Interpersonal Relationship with Navigator (PSN-I) measure for patients undergoing diagnostic and/or therapeutic cancer care.
We administered the PSN-I to 783 participants from the nine different sites of the National Cancer Institute sponsored Patient Navigation Research Program. We evaluated the latent structure and internal consistency of the PSN-I using principal components analysis (PCA) and Cronbach coefficient alpha (α), respectively. We used correlation analyses to examine divergence and convergence of the PSN-I with the Patient Satisfaction with Cancer-related Care (PSCC), the Rapid Estimate of Adult Literacy in Medicine (REALM) Long Form, and patients' demographics.
The PCA revealed a coherent set of items that explicates 76.6% of the variance in PSN-I. Reliability assessment revealed high internal consistency (α ranging from 0.95 to 0.96). The PSN-I had good face validity as well as convergent and divergent validities as indicated by moderate correlations with score on the PSCC (all ps < 0.0001) and non-significant correlations with primary language, marital status, and scores on the REALM Long Form (all ps > 0.05).
The PSN-I is a valid and suitable measure of satisfaction with a patient navigator for the present sample.
患者导航员（PN）是解决癌症相关护理中种族和社会经济差异的一种方法。患者导航员为服务不足的患者提供后勤和情感支持，以促进他们成功完成诊断和治疗护理。然而，由于缺乏衡量满意度的工具，患者对与导航员关系的满意度知之甚少。
本研究的目的是验证用于接受诊断和/或治疗性癌症护理的患者对人际关系满意度与导航员（PSN-I）测量的有效性。
我们向来自美国国立卫生研究院赞助的患者导航研究计划的九个不同地点的 783 名参与者发放了 PSN-I。我们分别使用主成分分析（PCA）和 Cronbach 系数 alpha（α）评估 PSN-I 的潜在结构和内部一致性。我们使用相关分析来检查 PSN-I 与患者对癌症相关护理的满意度（PSCC）、成人医学阅读快速估计（REALM）长式和患者人口统计学的差异和收敛。
PCA 揭示了一组具有一致性的项目，这些项目说明了 PSN-I 中 76.6%的差异。可靠性评估显示出高的内部一致性（α 值范围为 0.95 至 0.96）。PSN-I 具有良好的表面效度，以及良好的收敛和发散效度，这表明与 PSCC 的评分呈中度相关（所有 ps<0.0001），与主要语言、婚姻状况和 REALM 长式的评分呈非显著相关（所有 ps>0.05）。
PSN-I 是一种针对本研究样本的有效和适合的患者导航员满意度测量工具。
