A social network approach to measuring social interaction related to change of health behavior required 460 participants in a health promotion program to nominate up to five network members and to rate the supportiveness of each person in changing health behavior during the previous year. Exploratory factor analysis of intercorrelations of the eight items suggested two factors representing supportive and negative interaction with internal consistency reliability of .89 and .61, respectively.
一种用于衡量与健康行为改变相关的社交互动的社交网络方法，要求一项健康促进计划中的460名参与者提名最多五名网络成员，并对每个人在过去一年中改变健康行为的支持程度进行评分。对八项指标的相互关系进行探索性因素分析，结果表明有两个因素，分别代表支持性互动和负面互动，其内部一致性信度分别为0.89和0.61。
