This study examined the concurrent validity and clinical correlates of the Constructive Thinking Inventory (CTI), a measure of experiential coping, in 551 adolescents aged 14-18 years with and without Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) substance use disorders (SUDs). The CTI was correlated with depression, anxiety, and conduct problems. After controlling for demographics and comorbid lifetime psychiatric disorders, the CTI scales of Behavioral Coping and Categorical Thinking distinguished adolescents with and without SUDs. Implications of these findings for assessment and treatment are discussed.
