“Results
Actissist was feasible (75% participants used Actissist at least once/day; uptake was high, 97% participants remained in the trial; high follow-up rates), acceptable (90% participants recommend Actissist), and safe (0 serious adverse events), with high levels of user satisfaction. Treatment effects were large on negative symptoms, general psychotic symptoms and mood. The addition of Actissist conferred benefit at post-treatment assessment over routine symptom-monitoring and treatment as usual.”
I read it. I just don’t have a clue what it’s about. 
It sounds like a smartphone app which includes symptoms tracking, but no idea why it would improve negative symptoms. Maybe it has some goal setting, reporting whether you did self care etc.
