Study summary

The aim of the present single-centered pre-post study is to assess the feasibility and to investigate the putative efficacy of an emotion-oriented group intervention for patients with psychosis. Patients with early psychosis in an inpatient unit receive a manualized group intervention focussing on emotional stability and emotion regulation (8 weekly sessions). Assessment will be performed at pre-therapy, post-therapy (after eight sessions and four weeks) and after a follow-up period of 12 weeks (8 weeks post therapy) and includes personal therapy goals and their realization, psychopathology, social functioning and emotion regulation skills as a putative mediator of change.

Read the detailed description

The aim of the present single-centered pre-post study is to assess the feasibility and to investigate the putative efficacy of an emotion-oriented cognitive-behavioral group intervention for patients with psychosis.

Patients with psychosis in an inpatient unit are informed on the study and written consent is obtained. At start of therapy, psychopathological interviews and self-report questionnaires are performed. Participants are reassessed after the intervention of 8 sessions (approximately 8 weeks) and after a follow-up period of 8 additional weeks).

Patients are enrolled in a manualized group therapy over 8 sessions including 7 modules. In the first session, group rules are obtained and individual therapy goals are elaborated and developed for each patient. In the next seven sessions, in each session a new module is presented to the patient and the skills are trained in training sessions and role plays.

Module 1 informs on emotions and their role in mental health, module 2 informs on techniques/skills in order to cope with negative emotions more generally. In module 3, mindfulness is presented as a technique to reduce the impact of negative emotions on the patients' life and practised. In module 4, patients learn skills on how to reduce their vulnerability for negative emotions in general. In Module 5, patients learn skills on how to cope with anger, Module 6 teaches skills on how to cope with guilt and shame, Module 7 is presented in the last session and includes skills on how to improve general emotional stability and to prevent relapse.

Training: Therapists are psychologists or psychiatrists that are currently in postgraduate training of Cognitive Behavior Therapy and received 8 sessions of additional training by the study PI.

Primary outcome variables are attainment of the individual therapy goals of the patient (Goal Attainment Scale) and reduced general psychopathology (PANSS total score) after 8 sessions therapy. Secondary outcomes are depressive symptoms (Calgary Depression Scale for Schizophrenia), social functioning (Role functioning scale), self-reported delusions (Peters et al. delusions inventory), self-reported persecutory delusions (Paranoia checklist), emotion regulation skills (Emotion Regulation Skills Questionnaire, Emotion regulation questionnaire, Emotion Regulation Inventory), self-esteem (Rosenberg Self-esteem Questionnaire) and the Beliefs About Stress Scale (BASS). Furthermore, patients are asked to assess feasibility and acceptance of the group intervention. Emotion regulation skills and self-esteem are also tested as putative mediators of change.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Goal attainment scale (GAS, Kiresuk & Sherman, 1968)

    Patients select in an individual session with their therapist their most important therapy goal and mark on a scale from 0-100, whether it is reached at the present day. The mean score will be used (range between 0 and 100 with higher scores indicating higher values)

    Time frame: Change between start of therapy and end of therapy (approximately 8 weeks).

  2. Positive and Negative Scale Total score (Kay et al., 1992)

    Interview to assess positive symptoms, negative symptoms and general psychopathology in the last week. Range 30-210 with higher scores indicating more pronounced distress.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 5, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
