Objective: To ascertain whether ADHD symptoms, and associated problems, are negatively related to subjective well-being. Method: The Satisfaction With Life Scale (SWLS) was completed by 369 university students, along with the Reasoning & Rehabilitation (R&R) ADHD Training Evaluation (RATE), the Diagnostic and Statistical Manual of Mental Disorders ( DSM-IV) Scale for current ADHD symptoms, and the Depression Anxiety Stress Scales (DASS). Results: The SWLS was negatively correlated with all the other measures, and the strongest correlations were with the Total RATE score. A multiple regression analysis showed that the variables in the study accounted for 22% and 25% of the variance of the SWLS among males and females, respectively. Among males poor social functioning was the best predictor of dissatisfaction with life, whereas among females it was poor emotional control. Conclusion: Both ADHD symptoms and associated problems are significantly related to poorer satisfaction with life. ( J. of Att. Dis. 2009; 12(6) 507-515 )
