Cognitive distortions are systematic biases in an individual’s thinking that maintain a person’s belief in their negative views of themselves or others, even in the presence of contradictory evidence. The Inventory of Cognitive Distortions (ICD), created by Yurica and DiTomasso, measures distorted thinking in adults. Currently, there is not a youth measure of distortions that adequately encapsulates the range of distorted thinking that may be present in youth. Therefore, the purpose of the current study was to create and validate a newly designed instrument of cognitive distortions, The Inventory of Cognitive Distortions-Youth Version (ICD-YV), with youth ages 11 to 17. Participants were recruited through social media,, local school and community organizations and local business and university listservs. The psychometric properties (content validity, construct validity, convergent validity and internal consistency reliability) of the ICD-YV were assessed. Identifying a valid and reliable tool to evaluate cognitive distortions in youth is needed to facilitate better identification of these patterns of thinking and facilitate early identification and more accurate and targeted treatment, from a cognitive-behavioral perspective.
