According to the Substance Abuse and Mental Health Services Administration’s (SAMHSA’s) National Survey on Drug Use and Health, 23.5 million persons aged 12 or older needed treatment for an illicit drug or alcohol abuse problem in 2009 (9.3 percent of persons aged 12 or older). Unfortunately, addiction treatment completion rates remain relatively low, looming around 50%. In order for treatment programs to be more effective, it is imperative that risk factors for attrition are identified, and that programs strive to combat these risks through personalized engagement and individually tailored treatment programs. This study aims to identify specific risk factors for treatment attrition in the Intensive Outpatient Program (IOP) at the Loma Linda Behavioral Medical Center (LLUBMC). With this understanding, we may be able to target patients at risk for attrition, and tailor treatment programs in order to maximize completion of treatment, influencing higher efficacy and lower relapse rates.
