Aims: This study investigates the effect of significant others and demographic factors associated with treatment outcomes and length in treatment of pathological gamblers who received treatment through Oregon Problem Gambling Services (OPGS). Design: This is a cohort study of individuals who received gambling treatment. Setting: OPGS provides in- and outpatient services for gamblers in Oregon, as well as for family members of gamblers. Participants: Participants were 4,410 adult gamblers who discharge from treatment between August, 2001 and April, 2007. 307 gamblers had significant others participate in family treatment programs. Measurements: OPGS Enrollment Forms provided gambler gender, age, ethnicity, education level, employment status, gambling-related debt, and whether the gambler had a significant other at the time of enrollment. OPGS Termination Forms provided information on the type of discharge (successful/unsuccessful) and treatment length (in days). Additionally, data from matched significant others indicated which gamblers had significant others participate in treatment. Findings: Results showed that age, ethnicity, gambling debt, and having a significant other are associated with gambling treatment outcomes of success or non-success. Education level moderates the effect of having a significant other participate in treatment. Additionally, it was found that age, ethnicity, education, employment, and having a significant other participate in treatment significantly impacted gamblers' length in treatment. Conclusions: These findings indicate that there may be a benefit to integrating significant others in gambling treatment methods. Significant others may act as social supports for gamblers seeking treatment, and involving loved ones in gambling treatment models may positively affect gambler treatment outcomes.
