This paper describes the development and psychometric evaluation of scales measuring the dimensions of 'will' (belief, confidence, prior action and desire) for heart health promotion specifically and health promotion in general at both an individual and organizational level. Content validity was established through a series of focus groups and expert opinion assessments, based on a compilation of capacity-assessment instruments developed by other provinces involved in the Canadian Heart Health Initiative and the literature. Psychometric analyses of questionnaire data provided empirical evidence of the construct validity and reliability of the 16 individual and 21 organizational level 'will' scales. A series of principal component analyses assisted in verifying the unidimensionality of the measures and all scales yielded high internal consistencies with Cronbach's alpha coefficients ranging between 0.73 and 0.96. These measures can be used by both researchers and practitioners for assessing the 'will' to promote heart health specifically and health promotion in general.
本文描述了专门用于促进心脏健康以及在个人和组织层面促进整体健康的“意愿”（信念、信心、先前行动和愿望）维度测量量表的开发和心理测量评估。基于参与加拿大心脏健康倡议的其他省份开发的能力评估工具汇编以及相关文献，通过一系列焦点小组和专家意见评估建立了内容效度。对问卷数据的心理测量分析为16个个人层面和21个组织层面的“意愿”量表的结构效度和信度提供了实证证据。一系列主成分分析有助于验证这些测量的单维度性，所有量表都具有较高的内部一致性，克朗巴哈系数在0.73至0.96之间。研究人员和从业者均可使用这些测量方法来评估促进心脏健康以及整体健康促进的“意愿”。
