Summary
Video recording multitasking performance offers a reliable method for assessment. This approach, using the Multiple Errands Task (MET), showed strong inter-rater reliability, supporting its use in clinical and research settings.
Area of Science:
- Cognitive Psychology
- Neuropsychology
- Human-Computer Interaction
Background:
- Multitasking measures in naturalistic settings are sensitive to executive functioning deficits.
- Traditional assessment methods are time-consuming and prone to bias.
- Video recording offers a potential solution to these limitations.
Purpose of the Study:
- To investigate the practicality and accuracy of using video ratings for off-line scoring of multitasking performance.
- To evaluate the reliability of video-based assessments compared to live scoring.
Main Methods:
- Nineteen participants performed the Multiple Errands Task (MET) while wearing a body-worn camera.
- Performance was scored live by an examiner and independently by a rater viewing video footage.
- Inter-rater reliability between live and video scoring was analyzed.
Main Results:
- Significant correlations were found across all MET variables between live and video ratings.
- The study demonstrated strong inter-rater reliability for the video rating method.
- Video assessment appears to be a practical and reliable scoring approach.
Conclusions:
- Initial evidence supports the use of video raters for assessing performance on the Multiple Errands Task.
- Video recording can enhance the objectivity and efficiency of executive functioning assessments.
- This method holds promise for improving the evaluation of organizational skills.
