Implementation of a Mobile DBT App and Its Impact on Suicidality in Transitional Age Youth with Borderline...

Contemporary performance and accessibility are features that enable mobile devices to be increasingly beneficial in the context of optimizing the treatment of psychiatric disorders. Smartphones have the potential to effectively support psychotherapeutic interventions among adolescents and young adults who require them. In the present study, the use and subjective influence of a smartphone app with content from dialectical behavior therapy (DBT) was investigated among transitional age youth (TAY) with borderline personality disorder, focusing on suicidality and non-suicidal self-injury (NSSI), in a natural setting. A longitudinal qualitative approach was used by means of individual semi-structured interviews, where participants were asked about their experiences and associated emotions before and after a testing period of 30 days. A total of 13 TAY with a diagnosed borderline personality disorder between the ages of 18 and 23 were included. Six overarching themes were identified through qualitative text analysis: (1) experiences with DBT skills, (2) phenomenon of self-harm, (3) feelings connected with self-harm, (4) dealing with disorder-specific symptoms, (5) prevention of self-harm, and (6) attitude toward skills apps. In general, the provision of an app with DBT content achieved a positive response among participants. Despite a small change in the perception of suicidality and NSSI, participants could imagine its benefits by integrating their use of the app as a supportive measure for personal psychotherapy sessions.
