上下文退伍军人健康管理局使用丧亲家庭调查（BFS）来评估临终（EOL）护理的结果。最初，BFS是以电话调查的方式进行的，但从2012年10月开始转变为邮件调查。过渡需要使用这种新的管理模式对工具的有效性进行评估。本研究的目的是验证邮件版本，并测试测量不变性（MI）在两种管理模式。2009年10月至2013年9月期间分别验证了BFS的电话和邮件版本。使用一系列验证性因素分析（CFA）评价MI。通过计算Cronbach α系数和检查具有和不具有质量护理指标的组的BFS因子得分之间的差异来评估结构效度。例如，在一个实施例中，接受姑息治疗咨询）。我们的样本包括35，682名死者的BFS评分（27，109次电话调查; 8573次邮件调查）。BFS项目得分略有偏斜，电话和邮件版本的得分较高。每个BFS项目的平均缺失率是最小的，每个版本只有2%。CFA模型证明了各给药模式的维度、几何、度量和因子均值不变性。无论管理模式如何，当患者接受EOL质量护理指标时，BFS因子评分始终较高。这些发现证明了MI和强大的心理测量特性的BFS跨管理模式。(C)爱思唯尔公司出版代表美国临终关怀与姑息医学学会。
Context. The Veterans Health Administration evaluates outcomes of end-of-life (EOL) care using the Bereaved Family Survey (BFS). Originally, the BFS was administered as a telephone survey but was transitioned to a mail survey beginning October 2012. The transition necessitated an evaluation of the tool's validity using this new mode of administration.Objectives. The objective of this study was to validate the mail version and to test for measurement invariance (MI) across the two administration modes.Methods. Telephone and mail versions of the BFS were validated separately between October 2009 and September 2013. MI was evaluated using a series of confirmatory factor analyses (CFAs). Construct validity was evaluated by calculating Cronbach alpha coefficients and examining differences between BFS factor scores for groups with and without quality care indicators (e. g., receipt of a palliative care consult).Results. Our sample consisted of 35,682 decedent BFS scores (27,109 telephone surveys; 8573 mail surveys). BFS item scores were slightly skewed, with a predominance of higher scores for both the telephone and mail version. The average missing rate for each BFS item was minimal, just 2% for each version. The CFA models demonstrated dimensional, configural, metric, and factor mean invariance across administration modes. BFS factor scores were consistently higher when a patient received EOL quality care indicators regardless of mode of administration.Conclusion. These findings demonstrate the MI and robust psychometric properties for the BFS across administration modes.
