There are approximately 1.3 million youth who have been diagnosed with a co-occurring disorder. The purpose of this study was to analyze the relationship between the type of therapy (brief strategic family therapy or family functional therapy), demographic factors (age, race, type of drug used), and therapy discharge status (successful or unsuccessful) in male youth with a co-occurring disorder of attention-deficit hyperactivity disorder and substance use disorder. A correlational research design of a cross-sectional nature was used for this study and secondary data were obtained from a mental health agency located in Hampton Roads Virginia. The theoretical basis for this study was Bowens family systems theory. A purposeful convenience sample was used from archival data (n=392). Independent sample t-Tests were conducted to analyze differences between demographic groups and discharge status, and it was found that males whose drug of choice was alcohol had a statistically significant lower successful discharge rate (p=.031). Type of therapy unrelated to discharge status at a statistically significant level (p=.418). Results of a multiple logistic regression analysis showed that non-White/Caucasian males were 1.86 times more likely to have a successful discharge status from the program (p=.048). Age, drug type, and therapy used were unrelated to discharge status at statistically significant levels (p>.05). This study can educate therapists about their preconceived notions regarding ethnicity and the potential to successfully complete therapy. This could result in more empowerment shared with clients of these ethnic groups which could positively impact completion of therapy.
