Loneliness in schizophrenia: Just loneliness

Area of Science:

• Psychiatry
• Neuroscience
• Social Psychology

Background:

• Loneliness is highly prevalent in schizophrenia (∼80%).
• Mechanisms of loneliness in schizophrenia are not fully understood.
• Loneliness shares transdiagnostic factors with the general population.

Purpose of the Study:

• To explore the cognitive and neural underpinnings of loneliness in schizophrenia.
• To identify factors contributing to loneliness in this population.
• To inform the development of targeted interventions.

Main Methods:

• Review of existing literature on loneliness in schizophrenia.
• Analysis of cognitive biases (e.g., mistrust).
• Examination of structural, genetic, environmental, neural, and cardiometabolic factors.

Main Results:

• Loneliness in schizophrenia is linked to mistrustful cognitive biases and social barriers.
• Genetic, environmental, neural, and health factors may also contribute.
• Many contributing factors align with a transdiagnostic model of loneliness.

Conclusions:

• Further research on schizophrenia should incorporate measures of social isolation and loneliness.
• Novel interventions are needed to address loneliness by targeting neurocognitive biases and environmental factors.
• Interventions like cognitive bias modification and mindfulness show potential.
