Abstract

Objective:

Investigate whether treatment response in people at clinical high risk of psychosis (CHR) is predicted by their cognitive performance.

Method:

128 CHR outpatients were randomized into two treatment groups, one receiving integrated psychological intervention (IPI), including psychoeducation, the other receiving supportive counselling (SC) for 12 months. Multiple regression analysis was used to identify neurocognitive predictors of treatment response in a subgroup of n = 105, measured by symptomatic and functional improvement at 1-year follow-up.

Results:

In the IPI, treatment response was associated with performance of executive control and processing speed (R² = 0.27, p = 0.002). In both treatment groups, performance of working memory/attention was a significant predictor (IPI: R² = 0.15, p = 0.039, SC: R² = 0.19, p = 0.012).

Conclusion:

Cognitive performance is associated with treatment response in CHR people. The enhancement of cognitive performance is a useful target of early intervention.

Psychosis: Goals of Pharmacotherapy

Psychosis: Goals of Pharmacotherapy

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.

Treatment Strategies for Psychological Disorders

Treatment Strategies for Psychological Disorders

Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...

Psychological and Sociocultural Causes of Schizophrenia

Psychological and Sociocultural Causes of Schizophrenia

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...

Cognitive Therapy

Cognitive Therapy

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...

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Participant modeling involves therapists demonstrating calm and effective behaviors in...
