Assessing functional performance using computer-based simulations of everyday activities.

Area of Science:

• Neuroscience
• Psychiatry
• Gerontology

Background:

• Current functional capacity (FC) assessments for schizophrenia patients are often in-person and rely on informants or paper-based methods.
• These traditional methods present logistical challenges and limit remote assessment capabilities, which is crucial for schizophrenia patient care.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of a novel computer-based assessment battery for measuring functional capacity in older adult schizophrenia patients.
• To compare this technology-based battery with standard in-person assessments for cognition and FC.

Main Methods:

• A computer-based assessment battery simulating everyday activities (e.g., financial management, prescription refills, form completion) was developed.
• The battery was administered to 77 older adult patients with schizophrenia and 24 healthy controls at two time points.
• Performance was compared to standard in-person cognitive and FC assessments.

Main Results:

• The computer-based battery demonstrated sensitivity to group differences in functional capacity.
• Performance on the battery showed moderate correlations with standard cognitive measures and convergence with standard FC measures.
• The assessment exhibited good test-retest reliability and was feasible for remote administration without a healthcare professional.

Conclusions:

• Technology-based assessment protocols are feasible for older adults and schizophrenia patients.
• The developed computer-based battery effectively measures functional capacity, overcoming the logistical limitations of traditional methods.
• This approach facilitates remote assessment, improving accessibility and efficiency in evaluating functional capacity for schizophrenia patients.
