Abstract

This study examined the strength and specificity of the relationship between intolerance of uncertainty (IU) and worry with regards to depression in a nonclinical sample. The hypotheses were the following: (1) IU would be more highly and specifically related to worry than to depression; and (2) worry would be more highly and specifically related to IU than to dysfunctional attitudes (a cognitive process involved in depression). Two-hundred and forty (240) undergraduate students completed self-report questionnaires that assessed worry, intolerance of uncertainty, depression, and dysfunctional attitudes. Both hypotheses were confirmed: IU was more highly (although not significantly) and specifically related to worry than to depression; and worry was more highly and specifically related to IU than to dysfunctional attitudes. The findings are discussed in terms of their theoretical and clinical implications.
