Summary
Group cognitive behavioural therapy for psychosis (CBTp) shows potential benefits for schizophrenia patients
Area of Science:
- Psychiatry
- Psychology
- Clinical Trials
Background:
- Schizophrenia is a severe psychotic disorder with positive and negative symptoms.
- Cognitive Behavioural Therapy (CBT) targets thought patterns to alleviate distress.
- Group CBT for psychosis (CBTp) is a cost-effective alternative to individual therapy for schizophrenia.
Purpose of the Study:
- To evaluate the efficacy and acceptability of group CBTp for individuals with schizophrenia or schizoaffective disorder.
- To compare group CBTp against standard care or other psychosocial interventions.
Main Methods:
- Systematic search of multiple databases and trial registries up to February 2021.
- Inclusion of 24 randomized controlled trials with 1900 participants.
- Data analysis using risk ratios and mean differences with random-effects models.
Main Results:
- Group CBTp showed no significant difference in study dropout rates or general quality of life compared to standard care.
- A potential advantage for group CBTp was observed in overall mental state (PANSS total scores) and global functioning (GAF, PSP, SDSS).
- No clear differences were found in depression, hospitalization rates, or most quality of life domains.
Conclusions:
- Group CBTp may offer benefits for overall mental state and global functioning in schizophrenia.
- Current evidence is limited by low sample sizes and lack of data on primary outcomes and adverse effects.
- Further high-quality research is necessary to establish firm conclusions on the efficacy of group CBTp.

Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

01:24Rational Emotive Behavior Therapy
105
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

01:29Psychological and Sociocultural Causes of Schizophrenia
181
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
