This study further highlights the importance of clinicians assessing for concomitant ADHD and psychological distress in adults.Adults with ADHD experience mental restlessness, akin to racing thoughts, but data on this symptom in ADHD remain scarce. Our study aims at investigating self-reported racing thoughts in adults with ADHD, and its relationship with affective dysregulation and insomnia. We were also interested in whether racing thoughts may aid differential diagnosis with bipolar disorder (BD). 182 adults with ADHD, 30 ADHD+BD, 31 hypomanic BD, and 20 euthymic BD patients completed the Racing and Crowded Thoughts Questionnaire (RCTQ). ADHD, anxiety, insomnia and depression symptoms, as well as affective temperament were also assessed in ADHD and ADHD+BD subjects. Results show that RCTQ scores were higher in ADHD compared to hypomania and euthymia and were associated with cyclothymic traits and anxiety. Moreover, in ADHD and ADHD+BD, racing thoughts increased in the evening and at bedtime and were associated with insomnia severity. In conclusion, self-reported racing thoughts are a neglected but an intrinsic feature of adult ADHD that is particularly related to cyclothymia and anxiety, but cannot differentiate ADHD and BD.Adolescent males are at particularly high risk of mental health problems and suicide. However, many in need are left undetected and untreated, and rates of help-seeking are low. To help explain this unmet need, the current study aimed to utilise Exploratory Factor Analysis to validate a measure of help-seeking attitudes using 16 items of the Mental Health Literacy Scale. Convergent validity was assessed through correlations of the factors with other measures capturing aspects of mental health literacy and psychological distress. Male adolescent sport participants (N=361) aged between 12 and 18 years participated in the
