本研究的目的是根据跨理论模型（TTM）开发四份问卷，以评估行为，完成医疗保健代理（HCP）。目的是（a）操作完成HCP的四个TTM结构和（B）评估问卷的心理测量特性。问卷的构建和内容效度建立使用专家小组。每个问卷和每个问卷内的分量表的内部一致性值> 0.79。验证性因素分析提供的证据表明，决策平衡和变化过程问卷各包含两个因素。我们的数据支持与HCP完成相关的TTM问卷的有效性和可靠性。(C)2009 Wiley Periodicals，Inc. Res Nurs Health 32：606-620，2009
The purpose of the study was to develop four questionnaires based on the transtheoretical model (TTM) to assess the behavior, completing a healthcare proxy (HCP). The aims were to (a) operationalize the four TTM constructs for completing a HCP and (b) evaluate the Psychometric properties of the questionnaires. The questionnaires were constructed and content validity established using an expert panel. Internal consistency values for each questionnaire and subscales within each questionnaire were > .79. Confirmatory factor analysis provided evidence that decisional balance and the processes of change questionnaires each contained two factors. Our data support validity and reliability of the TTM questionnaires related to HCP completion. (C) 2009 Wiley Periodicals, Inc. Res Nurs Health 32:606-620, 2009
