Objective

Reliable, valid, and precise measures of perceived cognitive functioning are useful in clinical practice and research. We present normative data, internal consistency statistics, item-level symptom endorsement, and the base rates of symptoms endorsed for the PROMIS® v2.0 Cognitive Function-Short Forms.

Method

The four-, six -, and eight-item short form of the PROMIS® v2.0 Cognitive Function scale assess subjective cognitive functioning. We stratified the normative sample from the U.S. general population (n = 1,009; 51.1% women) by gender, education, health status, self-reported history of a depression or anxiety diagnosis, and recent mental health symptoms (i.e., feeling anxious or depressed in the past week) and examined cognitive symptom reporting.

Results

Internal consistency was measured using Cronbach’s alpha and ranged from .85 to .95 for all three forms, across all groups. Mann–Whitney U test comparisons showed that individuals with past or present mental health difficulties scored significantly lower (i.e., worse perceived cognitive functioning) on the self-report questionnaires, particularly the eight-item form (history of depression, men: p < .001, Cohen’s d = 1.07; women: p < .001, d = .99; history of anxiety, men: p < .001, d = 1.06; women: p < .001, d = .98; and current mental health symptoms, men: p < .001, d = 1.38; women: p < .001, d = 1.19).

Conclusions

All three short forms of the PROMIS® v2.0 Cognitive Function scale had strong internal consistency reliability, supporting its use as a reliable measure of subjective cognitive functioning. The subgroup differences in perceived cognitive functioning supported the relationship between emotional and cognitive well-being. This study is the first to present normative values and base rates for several community-dwelling subgroups, allowing for precise interpretation of these measures in clinical practice and research.
