- Brief Summary
Auditory hallucinations (AH) are associated with distress and reduced functioning. Psychological interventions show some promising effects on psychopathology but have been less successful in reducing AH related distress, which patients report to be a priority. Research suggests that distress is associated with the hearer relating to AH in a passive and subordinate manner. A novel approach thus teaches assertive responses to AH through the use of experiential role-plays. A single centre pilot study in the United Kingdom evidenced a large effect of this approach on AH distress but independent multicentre studies are required to ascertain effectiveness across different settings. The planned feasibility trial aims to estimate the expected effect for a subsequent fully powered prospective, randomized, controlled, parallel-group, two-armed, multicentre, open trial set up to demonstrate that adding a Relating Module (RM) to Treatment as Usual (TAU) is superior to TAU alone. Feasibility questions relate to patient recruitment, therapist training and therapy monitoring in different types of psychological and psychiatric outpatient facilities.

Auditory hallucinations (AH) are associated with distress and reduced functioning. Psychological interventions show some promising effects on psychopathology but have been less successful in reducing AH related distress, which patients report to be a priority. Research suggests that distress is associated with the hearer relating to AH in a passive and subordinate manner. A novel approach thus teaches assertive responses to AH through the use of experiential role-plays. A single centre pilot study in the United Kingdom evidenced a large effect of this approach on AH distress but independent multicentre studies are required to ascertain effectiveness across different settings. The planned feasibility trial aims to estimate the expected effect for a subsequent fully powered prospective, randomized, controlled, parallel-group, two-armed, multicentre, open trial set up to demonstrate that adding a Relating Module (RM) to Treatment as Usual (TAU) is superior to TAU alone. Feasibility questions relate to patient recruitment, therapist training and therapy monitoring in different types of psychological and psychiatric outpatient facilities. A total of 75 patients diagnosed with a schizophrenia spectrum disorder (ICD-10, F2) and persistent distressing AH will be recruited across 4 sites and receive either 16 50-minute sessions of RM plus TAU or TAU alone within a 5-months period. Assessments will take place at baseline, at 5 months (post-intervention) and at 9 months (primary outcome).

- be ≥ 16 years of age
- be judged able to understand the full implications of their decision by the responsible psychiatrist or clinical psychologist.
Participant must not:
- have AH with a clear organic cause (e.g. brain disease or injury):
- have exclusively hypnagogic or hypnopompic AH,
- have a primary diagnosis of acute substance dependence (F1x.2)
- have completed a course of CBT for psychotic symptoms during the past year within which distressing AH have been targeted
- be currently participating, or be confirmed to participate in another interventional study in which they are receiving an intervention which utilizes psychological therapy ;
- be non-German speaking to the degree that the participant is unable to fully understand and answer assessment questions or give informed consent;
- be at immediate and serious risk to self or other.

- Arm && Interventions
Group Intervention Description Relating module + Treatment as usual Treatment as usual Participants in this arm will receive 16 weekly sessions with Relating Therapy (RT) over 5 months in addition to their treatment as usual. Relating module + Treatment as usual Relating Therapy Participants in this arm will receive 16 weekly sessions with Relating Therapy (RT) over 5 months in addition to their treatment as usual. Treatment as usual Treatment as usual Treatment as usual will include medication management, supportive brief counselling sessions and various types of psychosocial (e.g. social work guided support, peer support) and monitoring provided by Mental Health Services, with individual and family psychological therapies offered occasionally. Individual therapies may include Cognitive Behavior Therapy or psychodynamic interventions.
- Primary Outcome Measures
Name Time Method The Psychotic Symptom Rating Scales-AH-Distress factor score (PSYRATS-AH) 9 months after baseline assessment Auditory hallucination associated distress. The distress factor score of the PSYRATS-AH is the primary outcome as this is what has been prioritized by patients and is relevant to functioning. Confirmatory analysis will be conducted based on the intent-to-treat population (ITT), defined on the basis of the ITT principle. The aim is to show that the intervention group is superior to the control meaning that the mean score at 9 months adjusted for the baseline value is lower in the intervention group than in the control group. Lower scores indicate less distress.
- Secondary Outcome Measures
Name Time Method Time Budget Measure 5 and 9 months after baseline assessment Time that ist spent in social and vocational activities
Columbia Suicide Severity Rating Scale (C-SSRS) 5 and 9 months after baseline assessment Patients are interviewed about thoughts of wanting to complete suicide, active suicidal thoughts and intent to act on such thoughts (suicidal ideation, items 1-5) as well as about preparatory acts, aborted, interrupted or actual attempts (suicidal behaviour, 6-9). Completed suicide is rated on item 10. Scores on this scale range from 0 to 43 with higher scores indicating higher suicidal ideation
Number of rehospitalizations 5 and 9 months after baseline assessment Number of hospitalizations after study enrollment
EuroQuol Quality of Life Scale (EQ-5D-5L) 5 and 9 months after baseline assessment Health-related quality of life
he Psychotic Symptom Rating Scales - PSYRATS-AH-Frequency 5 and 9 months after baseline assessment Frequency of auditory hallucinations. Ranges from 0 to 4 with higher scores indicating higher frequency of auditory hallucinations
Patient Health Questionnaire-9 (PHQ-9) 5 and 9 months after baseline assessment Self-report scale measuring depressive symptoms. Total score ranges from 0 to 21with higher scores indicating more severe depressive symptoms
