Traditional drug and psychosocial therapy and available specific treatment strategies that directly target single key determinants of functional outcome like neurocognition, social cognition, and social behavioral skills have produced only moderate effects leaving an urgent need for further optimization. The present trial aims to more efficaciously improve functional outcome by integrating social behavioral and social cognitive treatment strategies. Six months of "Integrated Social Cognitive and Behavioral Skills Therapy (ISST)" will be compared with "Neurocognitive Remediation Therapy (NCRT)" as active control condition in a randomized multicenter clinical trial using a two group pre-post design with 2x90 patients in the remitted early phase of schizophrenia. Beyond "all-cause-discontinuation" as common primary outcome of all clinical trials of the ESPRIT-consortium, measures of functional outcome and subjective quality of life, patient experience as well as neurocognitive, social-cognitive and social behavioral measures will be assessed at baseline (V0), after completion of treatment (V6), and after 6 months follow-up (V12). ISST is expected to reduce the one-year discontinuation rate by 20% compared with NCRT, and to be superior in functional outcome measures by an effect size of at least d=0.42.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Written informed consent\n* DSM-IV-TR diagnosis of schizophrenia (295.10-30, 295.90)\n* PANSS at baseline: total score ≤ 75\n* Proficiency in German language.\n\nExclusion Criteria:\n\n* Lack of accountability\n* Positive urine drug-screening for illicit drugs at screening (except cannabinoids and benzodiazepines)\n* Serious suicidal risk at screening visit\n* Other relevant axis 1-diagnoses according to diagnostic interview (MINI);\n* Other relevant neurological or somatic disorders\n* Verbal IQ\\<80 (MWT-B)'}, 'identificationModule': {'nctId': 'NCT02678858', 'briefTitle': 'Efficacy of ISST in Schizophrenia', 'organization': {'class': 'OTHER', 'fullName': 'Heinrich-Heine University, Duesseldorf'}, 'officialTitle': 'Efficacy of "Integrated Social Cognitive and Behavioral Skills Therapy" (ISST) in Improving Functional Outcome in Schizophrenia', 'orgStudyIdInfo': {'id': 'ISST2015'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Integrated Social Cognitive and Behavioral Skills Therapy', 'description': 'The Integrated Social Cognitive and Behavioral Skills Therapy (ISST) shall target expressive and interactional behavior skills together with those social cognitive domains (facial and prosodic affect recognition, social perception, theory-of-mind) known to be most impaired (Savla, 2012) and most closely associated with functional outcome (Fett, 2012) in schizophrenia.', 'interventionNames': ['Behavioral: Integrated Social Cognitive and Behavioral Skills Therapy']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Neurocognitive Remediation Therapy', 'description': 'The Neurocognitive Remediation Therapy (NCRT) shall target impairments in attention, memory, and executive functions as an active comparator to the ISST.', 'interventionNames': ['Behavioral: Neurocognitive Remediation Therapy']}], 'interventions': [{'name': 'Integrated Social Cognitive and Behavioral Skills Therapy', 'type': 'BEHAVIORAL', 'otherNames': ['ISST'], 'description': 'The Integrated Social Cognitive and Behavioral Skills Therapy (ISST) is a newly developed treatment program.

The present version of NCRT is matched in dose, mode and scheme of application to the ISST, but differs from the ISST regarding targeted cognitive domains and preferred training strategy (predominantly drill and practice based). The NCRT provides the same amount of group interaction and companionship as well as the same amount of guided community activity as in the ISST, but is structured in such a way that interactional behavior is secondary (e.g. by competition-like tasks rather than cooperative tasks). Thus therapeutic attention and commitment are held constant across study conditions.', 'armGroupLabels': ['Neurocognitive Remediation Therapy']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Alzey', 'country': 'Germany', 'facility': 'Rheinhessen-Fachklinik Alzey', 'geoPoint': {'lat': 49.74657, 'lon': 8.11513}}, {'city': 'Berlin', 'country': 'Germany', 'facility': 'Vivantes Klinikum Am Urban', 'geoPoint': {'lat': 52.52437, 'lon': 13.41053}}, {'city': 'Bonn', 'country': 'Germany', 'facility': 'Dept. of Psychiatry and Psychotherapy, University of Bonn', 'geoPoint': {'lat': 50.73438, 'lon': 7.09549}}, {'city': 'Cologne', 'country': 'Germany', 'facility': 'Dept. of Psychiatry and Psychotherapy, University of Cologne', 'geoPoint': {'lat': 50.93333, 'lon': 6.95}}, {'city': 'Düsseldorf', 'country': 'Germany', 'facility': 'Dept. of Psychiatry and Psychotherapy, University of Düsseldorf', 'geoPoint': {'lat': 51.22172, 'lon': 6.77616}}, {'city': 'Tübingen', 'country': 'Germany', 'facility': 'Dept. of Psychiatry and Psychotherapy, University of Tübingen', 'geoPoint': {'lat': 48.52266, 'lon': 9.05222}}], 'overallOfficials': [{'name': 'Wolfgang Wölwer, Prof. Dr.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Dept. of Psychiatry and Psychotherapy, University of Düsseldorf'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'YES', 'description': 'Data shall be shared within the German research network ESPRIT (Enhancing Schizophrenia Prevention and Recovery through Innovative Treatments) as well as with other German research networks funded by the BMBF (call "Psychische Erkrankungen").'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Heinrich-Heine University, Duesseldorf', 'class': 'OTHER'}, 'collaborators': [{'name': 'University Hospital, Bonn', 'class': 'OTHER'}, {'name': 'University Hospital of Cologne', 'class': 'OTHER'}, {'name': 'University Hospital Tuebingen', 'class': 'OTHER'}, {'name': 'Zentralinstitut für Seelische Gesundheit Mannheim', 'class': 'OTHER'}, {'name': 'University of Cologne', 'class': 'OTHER'}, {'name': 'Rheinhessen-Fachklinik Alzey', 'class': 'OTHER'}, {'name': 'Vivantes Klinikum am Urban', 'class': 'UNKNOWN'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Prof. Dr. phil.', 'investigatorFullName': 'Wolfgang Wölwer', 'investigatorAffiliation': 'Heinrich-Heine University, Duesseldorf'}}}}
