This study was conducted to examine the correlations between Generalized Anxiety Disorder (GAD), worry, intolerance of uncertainty (IU), and problem-solving. The Generalized Anxiety Disorder Questionnaire for DSM-IV (GADQ-IV), the Penn State Worry Questionnaire (PSWQ), the Intolerance of Uncertainty Scale (IUS), and the Problem-Solving Inventory (PSI) were used to assess the relationship between GAD, worry, IU, and problem-solving. While the GADQ-IV, PSWQ, and the IUS assessed generalized anxiety, worry, and intolerance of uncertainty as single constructs, the PSI assessed problem-solving in terms of problem-solving confidence, approach avoidance style, and personal control. Data of 86 students in general psychology classes at Pittsburg State University was used for the study. Results indicated a significant positive association between anxiety and IU; a significant positive association between worry and IU; and a negative correlation between problem-solving confidence and intolerance of uncertainty. No correlations were found between IU and approach-avoidance style during problem-solving or between IU and personal control during problem-solving. These results indicate a high probability that high levels of IU are related to high levels of anxiety and worry, and low problem-solving confidence. It is hoped that the findings of this study will encourage improved treatment for GAD that will include a decreased intolerance of uncertainty and increased problem-solving confidence.
