Introduction: As there is a trend toward more people seeking medical help due to cognitive symptoms, validated and targeted questionnaires are increasingly important in the clinical evaluation process. The Cognitive Function at Work Questionnaire (CFWQ) was developed to identify and rate subjective cognitive symptoms of individuals active in working life. However, its psychometric characteristics have not been previously studied in a memory clinic setting.
Method: The factorial structure, internal consistency, test-retest reliability, and convergent validity of the CFWQ were studied in a memory clinic setting (N = 113). We also investigated the instrument’s ability to identify cognitive symptoms in a cohort of early-onset dementia (EOD, N = 22), mild cognitive impairment-neurological (MCI-n, N = 18), MCI due to mood, sleep, or other physical health problems (MCI-o, N = 59), and subjective cognitive decline (SCD, N = 14) patients.
Results: Based on factor analysis, eight cognitive subscales were identified covering main cognitive domains: Memory, Language, Executive Function, Speed of Processing, Cognitive Control, Name Memory, Visuospatial/Praxis and Attention. The internal consistency (α = 0.93) and the test-retest reliability (ICC = 0.91) were high. Several correlations (r = 0.19 — 0.33, p < 0.05) were documented between neuropsychological impairment level and CFWQ scores. EOD, MCI-n, MCI-o, and SCD groups did not differ statistically significantly in the levels of cognitive symptoms as measured by the CFWQ Total score. EOD group scored higher (p = 0.009) than other patient groups on the Visuospatial/Praxis subscale, but the difference between EOD and MCI-o groups turned insignificant after correcting for multiple testing.
Conclusions: The results of the study support the validity and reliability characteristics of the CFWQ in a memory clinic setting. The instrument is easy-to-use and has clinical utility in capturing the subjective cognitive symptoms of patients active in working life and who need a referral to a more detailed evaluation.
