The Mediating Role of Positive Rumination and Negative Rumination in the Relationship between Intolerance of Uncertainty and Interpersonal Problem Solving

The mediating roles of positive rumination and negative rumination in the relationship between intolerance of uncertainty and interpersonal problem solving were examined. Data were collected from the participants (n=983) using the Interpersonal Problem-Solving Scale, Positive and Negative Rumination Scale, and Intolerance of Uncertainty Scale. The indirect effect of intolerance of uncertainty on approaching problems in a negative way, constructive problem solving, insistent-persevering approach through the mediation of positive rumination was significant. The indirect effect of intolerance of uncertainty on lack of self-confidence and unwilling to take responsibility through the mediation of positive rumination was not significant. The indirect effect of intolerance of uncertainty on approaching problems in a negative way, lack of self-confidence, and unwilling to take responsibility through the mediation of negative rumination was significant. The indirect effect of intolerance of uncertainty on constructive problem solving and insistent persevering approach through the mediation of negative rumination was not significant. The findings of the study were discussed within the framework of the relevant literature and recommendations were made for future studies.
