Cognitive Remediation in Psychiatric Disorders is a two-volume work comprising Part A: Core Psychiatric Conditions (Volume 306) and Part B: Other Conditions, Contexts and Considerations (Volume 307). Together, the volumes provide a comprehensive, contemporary account of cognitive remediation and related cognition-oriented interventions across psychiatric, neurodevelopmental, lifespan, and other clinical contexts. Part A establishes the historical, conceptual, and practical foundations of cognitive remediation and examines its application across psychosis, serious mental illness, depression, bipolar disorder, obsessive-compulsive disorder, substance use disorders, and trauma-related disorders. Part B extends the discussion to personality disorders, eating disorders, behavioral addictions, ADHD, autism spectrum disorder, intellectual and developmental disabilities, cognitive concerns in older adults, HIV-associated neurocognitive disorders, multiple sclerosis, cognitive difficulties following electroconvulsive therapy, and emerging technology-enabled approaches. Across both volumes, contributors address intervention principles and mechanisms, clinical integration, adaptation and accessibility, metacognition and subjective cognition, memory, real-world skill acquisition, and functional and vocational outcomes. Together, the volumes provide a broad, integrated framework for understanding how cognition-oriented interventions can support recovery, participation, and everyday functioning across diverse clinical populations.
