Importance:
Psychometrically sound instruments are needed to evaluate executive functioning in the population of people with cancer.
Objective:
To develop and evaluate the reliability and validity of the Executive Function Performance Test-Enhanced (EFPT-E) in women after being treated for breast cancer.
Design:
Cross-sectional.
Setting:
University research laboratory.
Participants:
Women treated for breast cancer who had cognitive impairment (n = 12) and community control participants (n = 13).
Outcomes And Measures:
Evaluators (n = 8) independently scored a recorded administration of the EFPT-E to evaluate interrater reliability. An assessment battery, including the EFPT-E, was administered to evaluate the EFPT-E's known-groups validity and concurrent validity.
Results:
Excellent interrater reliability was observed for the EFPT-E total score and each subtask score (intraclass correlation coefficient = .90-.98). Moderate effect sizes were noted for the EFPT-E total score (Cohen's d = 0.5) and the total number of cues (d = 0.4) between the breast cancer group and the control group, with the breast cancer group demonstrating poorer performance. A limited correlation was found between the EFPT-E and the other cognitive measures.
Conclusions And Relevance:
The results support the EFPT-E's interrater reliability and warrant continued investigation to further establish its reliability and validity.
What This Article Adds:
Assessments are needed to quantify the impact of cognitive processes within functional tasks. The EFPT-E has been developed to assess the functional impact of mild cognitive impairment; initial testing with women with cancer showed excellent agreement between raters and promising results for validity.
