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.

Objective We examined the normative reference values, item-level symptom endorsement, internal consistency reliability, and the base rates of symptoms endorsed for the quality of life in neurological disorders (Neuro-QoL™) v2.0 Cognitive Function-Short Form. Method The Neuro-QoL™ v2.0 Cognitive Function-Short Form measures subjective cognitive difficulties. The normative sample from the U.S. general population was stratified by gender, education, health status, self-reported diagnosis of depression or anxiety, and recent mental health symptoms (i.e., endorsed frequent anxiety or depression symptoms in the last week). Results A cohort of 1,009 adults completed this scale and their mean score was 32.60 (SD = 6.89). The base rates of those who reported zero cognitive symptoms were consistently higher among the healthy samples (healthy men = 79.2%; all men = 63.9%; healthy women = 90.2%; all women = 80.0%). Endorsing three or more cognitive symptoms was more common in the mental health subgroups for both men (full men’s sample [n = 493] = 17.6%; depression subgroup [n = 70] = 30.0%; anxiety subgroup [n = 61] = 29.5%; mental subhealth group [n = 70] = 38.6%) and women (full women’s sample [n = 516] = 7.4%; depression subgroup [n = 123] = 13.0%; anxiety subgroup [n = 103] = 12.6%; mental health subgroup [n = 101] = 14.9%). Internal consistency was measured using Cronbach’s α and ranged from 0.87 to 0.94 across groups. Conclusions The Neuro-QoL™ v2.0 Cognitive Function-Short Form is a brief, efficient, and reliable measure of perceived cognitive difficulties. As expected, individuals with a favorable overall health and quality of life reported less cognitive symptoms than the total sample, whereas individuals with mental health difficulties reported more. These normative values and base rates stratified by gender, overall health, and mental health status may be useful when interpreting this measure in clinical practice.

Context: Student-athletes are commonly administered the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT®) battery at preseason baseline and post concussion. The ImPACT® is available in many different languages, but few studies have examined differences in cognitive performances and symptom ratings based on language of administration. Objective: This study examined differences on ImPACT® neurocognitive composites and symptom reporting at preseason baseline testing between student-athletes completing ImPACT® in Spanish versus English. Design: Cross-sectional study. Setting: Preseason baseline testing for a high school concussion management program in STATE-XXX. Patients of Other Participants: Adolescent student-athletes completing testing in Spanish (n=169) and English (n=169) were matched on age, gender, and health/academic history. Language groups were compared on each outcome for the full sample and for gender-stratified subsamples. Main Outcome Measure(s): Neurocognitive composite scores and individual and total symptom severity ratings from the ImPACT® battery. Results: Athletes tested in Spanish had lower neurocognitive performances on two of five composite scores (i.e., Visual Motor Speed, p<.001, d=.51; Reaction Time: p=.004, d=.33) and reported greater symptom severity (p<.001, r=.21). When analyses were stratified by gender, similar Visual Motor Speed differences were observed between language groups among boys (p=.001, d=.49) and girls (p=.001, d=0.49), whereas Reaction Time showed a larger group difference for boys (p=.012, d=.42) than girls (p=.128, d=.21). Language group differences in symptom reporting were similar for boys (p=.003, r=.22) and girls (p=.008, r=.21), with more frequent endorsement of physical and affective symptoms by athletes tested in Spanish. Conclusions: Language group differences in total symptom severity were small (r=.21), and language group differences in neurocognitive performances were small-to-medium (d=.05–.51). Compared to previous studies comparing athletes tested in Spanish and English on ImPACT®, smaller effects were observed in the current study, which may be attributable to close matching on variables related to neurocognitive performances and symptom reporting.
