The mediating role of positive rumination and negative rumination in the relationship between intolerance of uncertainty and interpersonal problem solving

In this study, the mediating roles of positive rumination and negative rumination in the relationship between intolerance of uncertainty and interpersonal problem solving were examined. For this purpose, this study was conducted with 983 university students. It was obtained from the participants, data was collected using the "Personal Information Form", "Interpersonal Problem Solving Inventory", "Positive and Negative Rumination Scale", "Intolerance of Uncertainty Scale". In the analysis of the data SPSS 26.0 package programme for Pearson Correlation Coefficient and SPSS Process Macro (Model 4) for the effect of mediating variables were used. A significant positive relationship was found between intolerance of uncertainty and the sub-dimensions of the interpersonal problem solving inventory (approaching problems in a negative way, constructive problem solving, lack of self-confidence, unwilling to take responsibility, insistent-persevering approach). A significant negative relationship was found between positive rumination and approaching problems in a negative way, lack of self-confidence and unwilling to take responsibility; a significant positive relationship was found between positive rumination and constructive problem solving and insistent-persevering approach. There was a significant positive relationship between negative rumination and approaching problems in a negative way, lack of self-confidence and unwilling to take responsibility, a significant negative relationship with constructive problem solving, and no significant relationship with insistent-persevering approach. It was found that 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. In addition, 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. It was found that 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. In addition, 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 related literature and suggestions were made for future research.
