Article Correctness Is Author's Responsibility: Construct validity of PROMIS® Cognitive Function in cancer patients and noncancer controls.

The article below may contain offensive and/or incorrect content.

Objective: The Patient-Reported Outcomes Measurement Information System Cognitive Function-Concerns® (PROMIS®-CF-Concerns) assesses self-reported cognitive complaints. Construct validity data for the CF-Concerns are few. To add to the literature, an analysis of criterion validity for cognitive complaints (European Organisation for Research and Treatment of Cancer–Cognitive Functioning subscale [EORTC-CF]) and cognitive performance (neuropsychological tests of memory [NIH Toolbox Auditory Verbal Learning Test] and verbal fluency [Controlled Oral Word Association Test]) and discriminant validity (self-reports of negative emotions of anxiety, depression, negative mood) are provided. A two-group comparison design was used. Method: Forty-four patients with chronic lymphocytic leukemia (CLL) and 44 age- and gender-matched noncancer controls completed self-report measures and neuropsychological tests. Spearman's rank correlations (rs) and independent-samples t tests were used. Results: Regarding criterion validity, PROMIS®-CF-Concerns significantly correlated with the EORTC-CF (rs = 0.77, p < .001), although not with tests of memory (âˆ'0.19) or verbal fluency (0.16). As expected, patients with CLL performed lower than did controls on neuropsychological tests (ps < .05) yet did not differ from controls on PROMIS®-CF-Concerns. PROMIS®-CF-Concerns was reliably and significantly correlated with negative emotions, with rs ranges across measures of âˆ'0.42 to âˆ'0.69 for the CLL group and âˆ'0.53 to âˆ'0.78 for controls. Conclusions: PROMIS®-CF-Concerns exhibited high internal consistency. Criterion validity was evidenced for cognitive complaints though not for cognitive performance as assessed here. In summary, the analysis supports the criterion validity of PROMIS®-CF-Concerns for cognitive complaints. It also covaries with self-reports of co-occurring anxiety, depression, and negative mood.
