Background: While Cognitive Remediation (CR) is effective in reducing cognitive and functioning difficulties in people with schizophrenia, there is variability in treatment response. Previous research suggested that participants' age may be a significant moderator of CR response.

Aim: To examine the impact of participants' age on CR outcomes.

International guidelines define relapse prevention for schizophrenia patients as a key therapeutic aim. However, approximately 80% to 90% of schizophrenia patients experience further symptom exacerbation after the first episode. The purpose of this study was to investigate whether group integrated neurocognitive therapy (INT), a cognitive remediation approach, reduces relapse rates in schizophrenia outpatients.

Negative symptoms often inhibit the social integration of people suffering from schizophrenia. Reducing severe negative symptoms (SNS) in a clinically relevant way is a major unmet need. The aim of this study was to investigate whether Integrated Neurocognitive Therapy (INT), a group cognitive remediation therapy (CRT), reduces SNS in schizophrenia outpatients.

Objective: Cognitive remediation (CR) approaches have demonstrated to be effective in improving cognitive functions in schizophrenia. However, there is a lack of integrated CR approaches that target multiple neuro- and social-cognitive domains with a special focus on the generalization of therapy effects to functional outcome.

Method: This 8-site randomized controlled trial evaluated the efficacy of a novel CR group therapy approach called integrated neurocognitive therapy (INT).

Objective: Elderly people with schizophrenia often suffer from cognitive impairments, which affect their social functioning. Today, only a few therapy approaches for middle-aged and older patients are available. The Integrated Psychological Therapy (IPT) combines neurocognitive and social cognitive interventions with social skills approaches.

This article outlines two examples of cognitive-behavior group therapy approaches for an integrative treatment of psychosis: the Integrated Psychological Therapy (IPT) and the Integrated Neurocognitive Therapy (INT). We present their theoretical background, content and conceptualization as well as recent empirical evidence for their efficacy. The article concludes that adapting these approaches to early intervention for people with high risk of psychosis seems promising.

The aim of the current pilot study was to compare two strategies in the application of the cognitive differentiation program of Integrated Psychological Therapy for people with schizophrenia. Twenty-six outpatients were randomly assigned to the application of the program in group sessions (CDg), or to its application in individualized sessions (CDi). The program provides cognitive exercises to promote better performance in cognition, and both groups of participants completed the same number of exercises following the same number of sessions per week.

Standardized recovery criteria go beyond symptom remission and put special emphasis on personal and social functioning in residence, work, and leisure. Against this background, evidence-based integrated approaches combining cognitive remediation with social skills therapy show promise for improving functional recovery of schizophrenia patients. Over the past 30 years, research groups in 12 countries have evaluated integrated psychological therapy (IPT) in 36 independent studies.

Cognitive impairments are currently regarded as important determinants of functional domains and are promising treatment goals in schizophrenia. Nevertheless, the exact nature of the interdependent relationship between neurocognition and social cognition as well as the relative contribution of each of these factors to adequate functioning remains unclear. The purpose of this article is to systematically review the findings and methodology of studies that have investigated social cognition as a mediator variable between neurocognitive performance and functional outcome in schizophrenia.

There are at least six psychotherapeutic treatments of personality disorders having received empirical and clinical validation in terms of their efficacy. These treatments are based on different theoretical models, namely the cognitive-behavioural, psychodynamic and interpersonal models. This article briefly presents these treatments, focusing on the process of therapeutic change.

The "Schema-focussed Emotive Behavioral Therapy" (SET) was developed by our research group as a new group therapy approach for patients with personality disorders from all clusters (A to C; DSM-IV). It was evaluated in a randomised controlled study (n = 93). Data were collected before and after treatment as well as one year after study entry.

Against the background of evidence-based treatments for schizophrenia, nowadays the implementation of specific cognitive and behavioral interventions becomes more important in the standard care of these patients. Over the past 25 years, research groups in 9 countries have carried out 30 independent evaluations of Integrated Psychological Therapy (IPT), a group program that combines neurocognitive and social cognitive interventions with social skills approaches for schizophrenic patients. The aim of the present study was to evaluate the effectiveness of IPT under varying treatment and research conditions in academic and nonacademic sites.
