A-103 Normative Reference Values and Item-Level Symptom Endorsement for the PROMIS® v2.0 Cognitive Function-8-Item Short Form in Adults with Mental Health Problems
Abstract Objective The purpose of the study is to present normative data and reliability statistics for the PROMIS® v2.0 Cognitive Function-8-Item Short Form for the total normative sample and subgroups with mental health problems. Method The PROMIS® v2.0 Cognitive Function 8-Item Short Form measures subjective cognitive difficulties (raw score range = 8–40). We stratified the normative sample from the US general population (n = 1,009; 51.1% women) by gender, self-reported history of a depression or anxiety diagnosis, and recent mental health symptoms (i.e., endorsed frequent anxiety or depression symptoms in the last week) and examined cognitive symptom reporting. Results Those with past or present mental health difficulties obtained lower raw scores on the measure, reflecting greater cognitive symptom reporting. This was apparent in men (all men, M = 31.06, SD = 7.68; depression group, M = 26.74, SD = 8.09; anxiety group, M = 26.95, SD = 7.54; mental health group M = 24.73, SD = 7.79) and women (all women M = 33.23, SD = 7.32; depression group, M = 29.78, SD = 8.57; anxiety group, M = 30.19, SD = 7.81; mental health group, M = 28.60, SD = 8.61). The base rates for endorsing three or more cognitive symptoms was greater in those with mental health problems (men: full sample = 19.7%; depression group = 37.1%; anxiety group = 32.8%; mental health group = 45.7%; women: full sample = 10.1%; depression group = 22.8%; anxiety group = 19.4%; mental health group = 24.8%). Internal consistency, as measured by Cronbach’s alpha, ranged from 0.92 to 0.95. Conclusions The PROMIS® v2.0 Cognitive Function-8-Item Short Form is a reliable measure of subjective cognitive functioning across genders and mental health status. Those with past or present mental health difficulties report a greater number of cognitive symptoms. It may be important to address these difficulties in clinical practice.
