What helps or hinders engagement in therapy for first-episode psychosis?
This meta-ethnography found that emotional distress alone can prevent engagement, while a therapist’s interpersonal skills, such as empathy, warmth, and collaboration, are crucial facilitators. Other key facilitators include meeting therapy expectations, respecting individual preferences, and reducing stigma. Engagement is dynamic and shaped by emotional, cultural, and service-level factors, such as digital access or staff continuity. Many barriers are modifiable, underscoring the importance of building flexible, culturally sensitive, and person-centered therapeutic relationships. For therapists, these findings highlight the significant impact of how therapy is offered, not just what is offered.

Imagery-Focused Therapy for Visual Hallucinations
Visual hallucinations are common in psychosis and difficult to treat. This study describes an innovative 10-session imagery-focused therapy (IFT-VH), which is designed to target visual hallucinations (VHs) through visual mental imagery techniques. The transdiagnostic case series reports promising results, including reduced VH severity and distress for many participants, improved secondary measures such as PTSD symptoms, and positive feedback regarding. The study highlights the potential of IFT-VH, as well as the need for longer interventions to address underlying traumas fully. These encouraging outcomes call for larger trials to validate the approach.

Cognitive behavioral self-help interventions for individuals experiencing psychosis
This review explored the effectiveness of CBT-based self-help interventions for individuals with psychosis. It found that seven out of ten studies showed a reduction in psychotic symptoms following self-help interventions. Secondary outcomes, such as depression, daily living skills, general well-being, and anxiety symptoms, also improved in many studies. Despite promising short-term outcomes, the long-term effectiveness of these interventions remains unclear. The review highlights the need for more high-quality, randomized controlled trials with longer follow-up periods to confirm these findings.
“After weighing up the findings, this review provides credible evidence for the short-term effectiveness of CBT-based self-help for reducing symptoms of psychosis… However, the longevity of effectiveness remains unclear.”
