Acquired brain injury (ABI) often leads to deficits in executive functioning (EF)
responsible for severe and long-standing disabilities in daily life activities.
The Cooking Task is an ecological and valid test of EF involving multi-tasking in
a real environment. Given its complex scoring system, it is important to
establish the tool's reliability. The objective of the study was to examine the
reliability of the Cooking Task (internal consistency, inter-rater and
test-retest reliability). A total of 160 patients with ABI (113 men, mean age 37
years, SD = 14.3) were tested using the Cooking Task. For test-retest
reliability, patients were assessed by the same rater on two occasions (mean
interval 11 days) while two raters independently and simultaneously observed and
scored patients' performances to estimate inter-rater reliability. Internal
consistency was high for the global scale (Cronbach alpha = .74). Inter-rater
reliability (n = 66) for total errors was also high (ICC = .93), however the
test-retest reliability (n = 11) was poor (ICC = .36). In general the Cooking
Task appears to be a reliable tool. The low test-retest results were expected
given the importance of EF in the performance of novel tasks.
