Ecological momentary assessments of cognitive performance are more variable in breast cancer survivors.

ABSTRACT: Cancer-related cognitive impairment is common and distressing. Research has primarily focused on differences in mean-level performance on laboratory cognitive tasks, but recent work has investigated within-person fluctuations, or intraindividual variability (IIV), in performance on laboratory-based tasks. The present study of ambulatory cognitive assessments in daily life evaluated whether cancer survivors differed from a comparison sample in mean-level performance, IIV, and within-group heterogeneity, as well as change in mean performance and IIV across the study. Breast cancer survivors (N = 47, M_age = 52.9) and a comparison sample (N = 105, M_age = 51.8) completed intensive longitudinal design protocols involving smartphone-based cognitive assessments up to 5 times
