Cognitive-behavioral therapy (CBT) for psychosis is recommended in many national guidelines, but dissemination into routine health care remains poor. This study tests whether an 8-week, CBT-oriented, Internet-based intervention (IBI) for people with psychosis is feasible, effective, and safe compared to care as usual.
METHOD
A sample of 101 people diagnosed with schizophrenia-spectrum disorders (age: M = 40.0, SD = 9.60; sex: 58% female) was randomly assigned to either an IBI for psychosis or a wait-list control condition. The primary outcome was a composite score of the positive factor of the Positive and Negative Syndrome Scale, the Launay Slade Hallucination Scale, and the paranoia checklist (clinicaltrials.gov, NCT02974400).
RESULTS
The composite score of psychotic symptom severity decreased more in the IBI condition than in the wait-list condition, reflected in the significant interaction of Time × Condition, F(1, 87.28) = 4.04, p = .047, dbetween = 0.24, 95% CI [-0.15, 0.63]. In the combined sample of participants who received immediate or delayed access to the intervention, the outcome improved further during the 6-month follow up period with a significant main effect of time, F(1, 69.35) = 9.59, p = .003, d = -0.37, 95% CI [-0.66, -0.07]. Participants were satisfied with the intervention (89%), and many used the intervention as defined per protocol (52%; at least four completed modules). Adverse events were infrequent (4.9%).
CONCLUSIONS
Internet-based, CBT-oriented interventions provide an add-on effect to care as usual and have the potential to narrow the psychological treatment gap in psychosis. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
