ABSTRACT
This study examined preliminary evidence of construct validity in a stand-alone memory concerns scale constructed from the Patient-Reported Outcomes Measurement Information System (PROMIS®) Cognitive Function item bank. A sample of 396 individuals, ages 18-75 (M = 33.7, SD = 12.7), from Spain and Latin America completed an online survey regarding lifetime exposure to factors associated with neurological compromise. The sample was 69.4% female. Respondents completed 8 items from the PROMIS® Cognitive Function item bank v1.0 dealing with memory concerns (MCS-8) along with the PROMIS® 8-item short form reflecting general cognitive concerns (CCS-8). The MCS-8 had high internal consistency reliability (Cronbach's alpha = 0.90), and represented a factor distinct from general cognitive concerns items on the CCS-8 in confirmatory factor analysis. Analysis of covariance controlling for sex, age, and education, showed that individuals endorsing history of exposure to sources of neurological compromise scored significantly lower T-scores on the MCS-8 than those who did not report any such history, F(1,390) = 6.4, p = 0.012. Older age was significantly associated with greater memory concerns, a relationship with age not observed with the CCS-8. As a stand-alone self-report measure, the MCS-8 appears to measure a construct distinct from general cognitive concerns that may be of interest for further research in clinical populations.
