Many studies of Attention Deficit/Hyperactivity Disorder (ADHD) have shown that the symptoms associated with the disorder persist into adulthood for as many as 10% to 60% of patients. The present study assesses life satisfaction, self esteem, quality of life, among adults with an ADHD diagnosis (n=13) and matched cohorts (n=13) across age gender and marital status. Also a qualitative open ended questionnaire was conducted. Previous research shows that inadequately or untreated ADHD decreases quality of life in relation to self esteem education, and employment (Brown, 2005). Research also suggests this disorder remains poorly understood by the general public (McCrann, 2006). A Kendall's Tau showed a strong positive significant relationship between life satisfaction and quality of life (tau=.761, p<.001, 2-tailed) for the adults with AD/HD, however a Kendall's Tau showed a weak non-significant relationship (tau=.307, p>.05, 2-tailed) between life satisfaction and self esteem for this group. A further recommendation is to increase the convenience sample of participants.
