Smartphone and Mobile Application Utilization Prior to and Following Treatment Among Individuals Enrolled in Residential Substance Use Treatment

• We examined technology use among patients in residential substance use treatment.
• Patterns of smartphone ownership were similar to that of the general U.S. population.
• Patients downloaded mobile apps on their phones and accessed the Internet.
• Younger age and more education were positively related to technology use.
• Smartphones and mobile apps may be useful for substance use treatment.

BackgroundFollowing completion of substance use treatment, it is crucial for patients to continue to utilize skills learned in treatment for optimal treatment outcomes. Mobile applications (apps) on smartphones offer a unique platform to promote utilization of evidence-based skills following completion of substance use treatment. Despite the promise of mobile apps and smartphones for treatment delivery, it remains unknown whether patients in substance use treatment in the United States have access to smartphones and utilize mobile apps on smartphones. The present study sought to determine smartphone utilization among individuals enrolled in one residential substance use treatment center in the U.S. catering specifically to low-income adults.MethodsParticipants included 251 individuals at a residential substance use treatment center in Washington DC admitted to the center between March, 2014 and January, 2015. During the intake process, participants completed interviewer-administered demographics and psychiatric questionnaires as well as a self-report of technology utilization.ResultsResults indicated that the majority of patients in this residential substance use treatment center owned mobile phones prior to treatment entry (86.9%) and expected to own mobile phones after leaving treatment (92.6%). Moreover, the majority of these phones were (68.5%) or will be smartphones (72.4%) on which patients reported utilizing mobile applications (prior to treatment: 61.3%; post treatment: 64.3%) and accessing the Internet (prior to treatment: 61.3%; post treatment: 65.9%).ConclusionsMobile phone and smartphone ownership among this sample were comparable to ownership among U.S. adults broadly. Findings suggest that smartphones and mobile apps may hold clinical utility for fostering continued use of treatment skills following substance use treatment completion.
