Details and patient eligibility

About

Approximately 25-50% of patients with schizophrenia experience treatment-resistant Auditory Verbal Hallucinations (AVHs), which contribute to the development of associated psychopathological disorders (e.g., anxiety, depression, suicidal ideation). Various validated psychotherapeutic strategies and tools for managing treatment-resistant AVHs have been combined into an integrative therapeutic program. The main objective of this study is to evaluate the efficacy of this program in reducing the frequency and intensity of AVHs, as well as its impact on comorbid psychopathology (e.g., depression, anxiety, self-esteem, substance use) in patients with schizophrenia or schizoaffective disorder who experience treatment-resistant AVHs.

Full description

The present study is a multicenter, prospective, randomized trial with two groups. Its main objective is to evaluate the efficacy of an integrative group therapy for drug-resistant Auditory Verbal Hallucinations (AVHs) in patients with schizophrenia or schizoaffective disorder. A total of 114 patients will be randomly assigned to the experimental or control group. The experimental group will receive integrative therapy sessions, while the control group will participate in an audio-visual group reflecting usual care.

Both experimental and control groups will attend fifteen weekly 1.5-hour sessions, supervised by a psychologist and a nurse trained in, or at least familiar with, cognitive-behavioral therapy. The sessions for the experimental group are organized as follows:

Sessions 1-2: Psychoeducation about AVHs Sessions 3-6: Metacognitive training Sessions 7-9: Monitoring voices using a notebook Session 10: Gaining control over voices through attentional distraction Session 11: Voice avatar creation Sessions 12-13: Dialogue with voices Session 14: Compassion-based mindfulness Session 15: Living with voices and community integration
