The results from the sample in this study suggest that closeness
and familiarity (social interactions) are good predictors of trust in a
social network community. A total of 56% of the variation in trust in a social network community may be explained by a user’s closeness and familiarity with a social network community
(Fig. 2B). Furthermore, based on our whole sample, trust in a
social network community is a salient factor influencing the
intention to purchase on social commerce websites.
In comparison to closeness, familiarity is a weaker measure of
social impact (see Fig. 2A). Our conclusion is consistent with that of
[41], who also argued that closeness/intimacy is a purer affective
concept and has a greater impact on online users’ behavior or
compared to familiarity.
