Abstract:In order to studied the antecedents of self-deprecating behavior,from perspective of context openness, this paper studied the interaction effect of two situational variables in online community: tie strength and context openness on sharing intention of self-deprecating information. Study 1 showed that compared to weak tie, sharing intention of self-deprecating information is higher. Furthermore, study 2 replicated the result of study 1 when online context openness was public. In contrast, the effect of tie strength on sharing intention of self-deprecating information will not exist when online context openness is private.
