Development of a mobile app for family members of Veterans with PTSD: identifying needs and modifiable factors associated with burden, depression, and anxiety

Family members of Veterans with posttraumatic stress disorder (PTSD) face high levels of burden that are poorly addressed by existing mental health services. Widely distributed mobile interventions could play a role in addressing these unmet needs. The purpose of this study was to characterize caregiver burden in those seeking a mobile app for self-management of stress symptoms and to develop a model to guide mobile interventions for family members. Those living with a Veteran with PTSD (n = 212) and interested in using a mobile intervention agreed to participate. The majority reported moderate-to-severe levels of depression (60%) and/or caregiver burden (59%). Relationship quality, communication, and self-efficacy for caregiving were the strongest predictors of negative outcomes (p's < .001), and qualitative results identified several additional unmet needs (e.g. relationship concerns, safety concerns). This study identifies potential mechanisms by which a mobile app could improve family functioning in the context of PTSD.
