The Gaylord Occupational Therapy Cognitive screen (GOT-Cog™) demonstrates moderate to excellent rater reliability and is sensitive to cognitive changes in long-term acute care inpatients. This cognitive screening tool supports occupational therapy treatment planning.
Area of Science:
- Rehabilitation Medicine
- Neuroscience
- Occupational Therapy
Background:
- The Gaylord Occupational Therapy Cognitive screen (GOT-Cog™) is a novel tool designed to aid occupational therapy treatment planning for inpatients.
- Previous research indicates GOT-Cog™ possesses strong content, construct, and criterion validity, along with good internal consistency.
Purpose of the Study:
- To evaluate the rater reliability of the GOT-Cog™.
- To assess the responsiveness of the GOT-Cog™ to changes in cognitive status over time.
Main Methods:
- A repeated-measures design was employed in a single long-term acute care hospital (LTACH).
- 192 inpatients received the GOT-Cog™ twice at admission and once at discharge.
- Interrater and intrarater reliability were assessed using intraclass correlation coefficients (ICCs); responsiveness was measured by effect size and score change.
Main Results:
- Scale-level interrater reliability for GOT-Cog™ was moderate to good (ICC=.80), while intrarater reliability was good to excellent (ICC=.84).
- Domain-level rater reliability varied from poor to excellent.
- A small effect size (d=.37) indicated responsiveness to cognitive changes from admission to discharge over an average stay of 24 days.
Conclusions:
- The findings support the validity and reliability of GOT-Cog™ for use in LTACH settings with medically complex inpatient populations.
- GOT-Cog™ demonstrates consistent performance across different raters and is sensitive to cognitive improvements during inpatient stays.
- The tool effectively supports occupational therapy treatment planning in this clinical environment.
