Neuropsychological test performance and self-reported cognitive functioning associated with work-related outcomes in occupationally active cancer survivors with cognitive complaints.

Abstract

RESULTS

Thirty percent of cancer survivors had lower than expected performance on neuropsychological tests. Higher overall neuropsychological test performance was associated with better work ability (Cohen's f² = 0.014) and physical functioning at work (Cohen's f² = 0.13). Furthermore, higher motor performance was associated with better work ability (Cohen's f² = 0.018). In addition, self-reported work-related cognitive complaints were associated with self-reported work-related outcomes (Cohen's f² = 0.13-0.35).

CONCLUSIONS

The percentage of cancer survivors with lower than expected performance on neuropsychological tests exceeded the percentage expected in a normal population. This neuropsychological test performance was weakly associated with various aspects of work ability and work functioning. Stronger associations were found between self-reported cognitive functioning at work with self-reported work-related outcomes.

IMPLICATIONS FOR CANCER SURVIVORS

A cognitive rehabilitation approach that specifically aims at reducing cognitive symptoms at work could be a valuable part of interventions that aim to improve work-related outcomes. Trial registration The study is registered at ClinicalTrials.gov (NCT03900806) at 03 April 2019 (current status: ongoing), https://clinicaltrials.gov/ct2/show/NCT03900806?term=NCT03900806&draw=2&rank=1.

METHODS

Baseline data of a multicenter, randomized controlled trial (n = 279) were used. Associations between neuropsychological test performance (Amsterdam Cognition Scan) and self-reported cognitive functioning (Cognitive Symptom Checklist-work) with work ability (Work Ability Index) and work functioning (Work Role Functioning Questionnaire) were examined using multivariate linear regression.

PURPOSE

To assess cognitive functioning in occupationally active non-central nervous system cancer survivors with cognitive complaints using neuropsychological tests, and to investigate the association between (1) formally assessed cognitive functioning and self-reported work-related outcomes and (2) self-reported cognitive functioning at work and self-reported work-related outcomes.
