Best Practices and Methodological Strategies for Addressing Generalizability in Neuropsychological Assessment.

Area of Science:

• Neuropsychology
• Psychology
• Research Methodology

Background:

• Generalizability is vital for replicating treatment effects across diverse demographics.
• Inconsistent guidelines for assessing and reporting generalizability hinder scientific progress.
• Historical research practices have often prioritized specific populations, impacting current generalizability.

Purpose of the Study:

• To synthesize obstacles and best practices for enhancing generalizability in research.
• To address generalizability as a contemporary challenge in neuropsychological assessment.
• To provide practical tools for evaluating and reporting assessment generalizability across populations.

Main Methods:
