Online Problem-Solving Training with and without Peer Support in Veterans with Unmet Mental Health Needs: A Pilot Study of Feasibility, User Acceptability and Patient Engagement (Preprint)
BACKGROUND Electronic health (eHealth) tools have the potential to meet the mental health needs of individuals who have barriers to accessing in-person treatment. However, most users have less than optimal engagement with eHealth tools. Coaching from peer specialists may increase engagement with eHealth. OBJECTIVE This pilot study aimed to 1) test the feasibility and acceptability of a novel, completely automated online system to recruit, screen, enroll, assess, randomize and then deliver an intervention to a national sample of military veterans with unmet mental health needs, 2) investigate whether phone-based peer support increased usage of an online problem-solving training compared to self-directed use and 3) generate hypotheses about potential mechanisms of action for problem-solving and peer support for future full-scale research. METHODS Veterans (n=81) with unmet mental health needs were recruited via social media advertising and enrolled and randomized to self-directed use of an online problem-solving training called Moving Forward (n=28), peer supported Moving Forward (n=27), or a waitlist control (n=26) (ClinicalTrials.gov NCT03555435). Participants completed pre and post study measures (8 weeks later) of problem-solving skills and confidence as well as mental health symptoms. Satisfaction was assessed at post-treatment and objective use of Moving Forward was measured with number of log-ins. RESULTS Automated recruitment, enrollment and initial assessment methods were feasible and resulted in a diverse sample of veterans with unmet mental health needs from 38 states. Automated follow-up methods resulted in 46% retention. Peer support was delivered with high fidelity and was associated with favorable patient satisfaction. Participants randomized to receive peer support had significantly more Moving Forward logins than self-directed Moving Forward participants, and those who received peer support had greater decreases in depression. Problem-solving confidence was associated with greater Moving Forward use and improvements in mental health symptoms among participants both with and without peer support. CONCLUSIONS Enrolling and assessing individuals in eHealth studies without human contact is feasible, but different methods or designs are necessary to achieve acceptable participant engagement and follow-up rates. Peer support shows potential for increasing engagement in online interventions and in reducing symptoms. Future research should investigate when and for whom peer support of eHealth is helpful. Problem-solving confidence should be further investigated as a mechanism of action for online problem-solving training. CLINICALTRIAL ClinicalTrials.gov NCT03555435
