Summary
Dysfunctional performance beliefs link neurocognitive deficits, negative symptoms, and disability in schizophrenia. Targeting these beliefs may improve patient outcomes.
Area of Science:
- Cognitive Psychology
- Psychiatry
- Neuroscience
Background:
- Negative symptoms and disability are significant challenges in schizophrenia.
- The cognitive model of negative symptoms proposes dysfunctional beliefs mediate between neurocognitive deficits and outcomes.
Purpose of the Study:
- To test the hypothesis that dysfunctional performance beliefs mediate the relationship between neurocognitive deficits, negative symptoms, and disability in chronic schizophrenia.
Main Methods:
- A hierarchal component model was employed.
- The study included 85 male patients diagnosed with chronic schizophrenia.
Main Results:
- A moderate to strong correlation was found between dysfunctional performance beliefs, neurocognitive deficits, negative symptoms, and disability.
- Results support the Hierarchal Component Model (HCM) of negative symptoms.
Conclusions:
- Disability in schizophrenia is mediated by a pathway involving dysfunctional performance beliefs, neurocognitive deficits, and negative symptoms.
- Dysfunctional performance beliefs play a critical role in this pathway.
- Interventions targeting dysfunctional beliefs could potentially improve disability in schizophrenia patients.

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,...

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.

Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

01:29Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
