Abstract

Objectives Generalized Anxiety disorder and Depression, one of the common problems in childhood andadulthood is associated with many problems in the field of health. This study aimed to investigate themediating role of Rumination in the relationship among Intolerance of Uncertainty (IU) and symptoms ofdepression and General Anxiety disorder (GAD). Methods In this descriptive correlational study, a sample of 250 students from Iran University of MedicalSciences were selected using cluster sampling method. The participants responded to intolerance ofuncertainty scale and Rumination scale, Generalized Anxiety disorder Questionnaire Inventory-revised(GAD-Q-IV), and Beck Depression inventory. The obtained data were analyzed using Structural EquationModeling (SEM). For statistical analysis, SPSS V. 22 and LISREL 85. 9 were used to classify, process, andanalyze the data and to investigate the hypotheses of the research. Results The evaluation of hypothetical model with fit indexes demonstrated that the hypothetical modelfits the measurement model (CFI=0. 98, NFI=0. 96, and RMSEA=0. 060). Structural relations analysis also indicated Intolerance of Uncertainty indirectly through Rumination overdepression and directly and indirectly general Anxiety disorder. Conclusion Thus, based on the current research findings, Rumination has a mediating role in relationshipbetween Intolerance of Uncertainty and symptoms of Depression and general Anxiety disorder. Consideringthese dimensions, the employed mechanisms can be useful in developing efficacious preventive andtherapeutic interventions for Depression.
