Summary
An 8-week Internet-based intervention (IBI) for psychosis significantly reduced symptom severity compared to usual care. This cognitive-behavioral therapy (CBT) approach shows promise in improving access to psychological treatments for psychosis.
Area of Science:
- Psychiatry
- Clinical Psychology
- Digital Health
Background:
- Cognitive-behavioral therapy (CBT) is recommended for psychosis but faces poor implementation in routine care.
- A significant gap exists in accessing psychological treatments for individuals with psychosis.
Purpose of the Study:
- To evaluate the feasibility, effectiveness, and safety of an 8-week, Internet-based intervention (IBI) for psychosis.
- To compare the IBI against care as usual in a randomized controlled trial.
Main Methods:
- 101 participants with schizophrenia-spectrum disorders were randomized to an IBI or a wait-list control.
- The primary outcome was a composite score measuring psychotic symptom severity.
Main Results:
- The IBI group showed a greater decrease in psychotic symptom severity compared to the wait-list group (p = .047).
- Participants reported high satisfaction (89%) with the intervention.
- Adverse events were infrequent (4.9%).
Conclusions:
- Internet-based, CBT-oriented interventions can augment standard care for psychosis.
- IBIs hold potential to reduce the disparity in psychological treatment access for psychosis.

Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

01:26Psychosis: Goals of Pharmacotherapy
361
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

01:29Psychological and Sociocultural Causes of Schizophrenia
361
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...
