Despite the availability of free, evidence-informed mental health mobile applications (apps) to support Veterans and Service Members, interventions are needed to ensure patients are aware of the developed resources. A psychoeducational group was developed and evaluated by a quality improvement project in the context of a Department of Veterans Affairs residential treatment program. Four weekly group sessions introduced 82 Veterans to two similarly themed apps at each group and supported Veteran installation, introduction to the clinical subject matter, app orientation and demonstration, and device/app troubleshooting. Although 94% owned a smartphone, prior to the group, seven of eight apps introduced during the group had been used by fewer than 10% of participants. Following group participation, the proportion of participants agreeing that they were comfortable using mental health apps increased from 33% at baseline to 75%. Similarly, relative to 54% of participants at baseline who agreed that they were aware of available mental health mobile applications, the proportion rose to 89% after the group. Most participants rated three apps as “helpful” or “very helpful” (Breath2Relax, Mindfulness Coach, and PTSD Coach) and most participants reported they were likely to use these apps in the future. Results and qualitative feedback identified needed improvements to the group, including the replacement of some featured apps and the inclusion of automated app usage metrics. Well-designed implementation studies of dissemination strategies are needed to inform best practices for the adoption of these promising interventions.
