An SMS text messaging intervention to improve clinical engagement in early psychosis: A pilot randomized-controlled trial

Disengagement of youth with psychosis from Early Psychosis Intervention (EPI) services continues to be a significant barrier to recovery, with approximately onethird prematurely discontinuing treatment despite the ongoing need. The current pilot trial sought to evaluate the preliminary efficacy and feasibility of a weekly short message service (SMS) intervention to improve engagement in EPI services. This was a longitudinal single -blinded randomized control trial in which participants were assigned to receive either an active or sham SMS intervention over nine months. Sixty-one participants with early psychosis between the ages of 16 and 29 were enrolled, randomized, and received at least part of the intervention. Primary outcomes consisted of participant clinic attendance rates over the course of the intervention and clinician -rated engagement. Secondary measures included patient -rated therapeutic rapport, attitude toward medication, psychopathology, cognition, functioning, and intervention feedback from participants. Compared to the sham group, participants receiving the active intervention did not show improved appointment attendance rates; however, did exhibit some improvements in aspects of engagement, including improved clinician -rated availability, attitude toward medication, positive symptoms, avolition-apathy and social functioning. Thus, contrary to our hypotheses, digitally augmented care did not result in enhanced engagement in EPI services, as measured by clinic attendance, although with some indication that it may contribute to improved attitude toward medication and, potentially, medication adherence. Weekly SMS text messaging appeared to result in a pattern of engagement whereby individuals who were improving clinically attended appointments less often, possibly due to inadvertent use of the intervention to check in with clinicians.
