Measurement of social interaction in change of health behavior.

ABSTRACT

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.
