OBJECTIVE
This study examines psychometric properties of a community activation assessment scale used for the evaluation of the Quebec project within the Federal Provincial Heart Health Initiative. The scale is composed of three sub scales, one for each of the intervention target risk factors.
METHODS
Data were collected by telephone interviews conducted with 199 key informants from the 24 communities of the project. Reliability was studied using Cronbach's alpha coefficients and intraclass correlations. Validity was explored with factor analysis techniques.
RESULTS
Subscales' internal consistency were very good, ranging from 0.71 to 0.83, but intraclass correlations between informants from the same communities were low. Factor analyses indicated a unidimensional structure for each scale.
INTERPRETATION
These results show that the scale seems to provide reasonable assessments of the opinion of key informants regarding activation in their community. However, ranking communities based on the aggregated scores from local key informants may lead to classification problems.
目的
本研究考察了一种用于评估联邦-省心脏健康倡议中魁北克项目的社区激活评估量表的心理测量特性。该量表由三个子量表组成，每个子量表针对一种干预目标风险因素。
方法
通过对该项目24个社区的199名关键信息提供者进行电话访谈收集数据。使用克朗巴赫α系数和组内相关性研究信度。采用因子分析技术探索效度。
结果
子量表的内部一致性非常好，范围从0.71到0.83，但同一社区的信息提供者之间的组内相关性较低。因子分析表明每个量表具有单维结构。
解读
这些结果表明，该量表似乎能合理评估关键信息提供者对其社区激活情况的看法。然而，根据当地关键信息提供者的综合得分对社区进行排名可能会导致分类问题。
