BackgroundConsistent monitoring of blood alcohol concentration through breathalyzers is critical for identifying reoccurrence. Little research has effectively utilized convenient wireless enabled breathalyzers that can measure blood alcohol concentration while enhancing treatment motivation for outpatient care. The current study attempted to understand the impact of wireless breathalyzers on treatment motivation and self-efficacy in remaining sober for individuals diagnosed with alcohol use disorder in an outpatient treatment facility. MethodsParticipants were assigned to one of two conditions: the experimental breathalyzer and the treatment as usual group. The groups were assessed by the University of Rhode Island Change Assessment (URICA), and on self-efficacy, measured by the Alcohol Abstinence Self-Efficacy Scale (AASE). The evaluation period took place over three months with a six-week follow-up evaluation. During the entirety of the evaluation period and post-study follow up, interviews occurred. ResultsAs a secondary analysis, the URICA's motivational scores were higher for participants receiving the experimental intervention at a two-month evaluation and at the six-week follow-up. The AASE's temptation to reoccurrence scores significantly reduced over time for both groups. The confidence to resist temptation was not significant. Three major themes emerged from the interviews, including the benefit of the breathalyzer facilitating their treatment, ease of device use, and technical issues. ConclusionsThe insights gained from this study will be important to develop cost-effective ancillary interventions for comprehensive alcohol dependence treatment. On-going monitoring enabled by new technology allows treatment providers to take an individualized disease-management approach as well as facilitating timely interventions by the treatment provider.
