Objective Montreal Cognitive Assessment (MoCA) and Alzheimer’s Disease 8 questionnaire (AD8) are widely used measures for clinical screening of dementia related disorders. Previous research on MoCA and AD8 has been solely focused on participant-report AD8 measures without consideration of informant reports. We hypothesize informant reported AD8 and participant MoCA scores will be inversely related, participant-reported AD8 will be weakly associated with MoCA performance, and informant reported AD8 will more reliably predictor cognitive performance. Methods Participants (N = 212) were seen from 2018 to 2020 through a free community screening service (Brain Health Check-In) at Banner Sun Health Research Institute in Arizona. First and second hypotheses were analyzed with Spearman’s Rho (r), third hypothesis utilized a linear regression. Results Both participant and informant reported AD8 directly correlated with overall cognitive performance classification (r = 0.639 [informant] confidence interval [CI] = .0552–0.712, p < .000; r = 0.610 [participant] CI = 0.518–0.688, p < .000). Informant reported AD8 ratings were significantly inversely correlated with MoCA performance (r = −0.497, p < .000). Participant reported AD8 ratings also inversely correlated with overall MoCA scores with a weaker association (r = −0.296, p < .000). Neither participant nor informant reported AD8 were able to reliably predict categorical cognitive performance classification, but informant reported AD8 (r = −.686, p < .000) did emerge as a reliable predictor of MoCA performance. Conclusion(s) This study extends and reaffirms prior research about AD8 and suggests both informant- and participant-reports are valuable; however, informant often provides more clinically useful information related to cognitive functioning.

Objective The FEAr pilot study was conducted to evaluate the construct validity of an instrument that measures self-reported fatigue levels among air medics (the Flight Risk Assessment [FRA] measure). Data Selection The population of interest, flight medics, is highly specialized and relatively small. As a result, non-probability, convenience sampling was used (N = 27). The participants were recruited from one air medical company with bases located across ten western states. Medics took two measures, the FRA and the PVT, three times a day, for three days. Data Synthesis To establish construct validity, scores on the FRA were compared to scores on the Psychomotor Vigilance Task (PVT), which is a widely used and validated measure to detect fatigue in field settings. The results of the study indicate that a total of five questions on the FRA was significantly and moderately correlated with the PVT efficiency score (r = -.49, p = .01). The mean reaction time was also significantly correlated with the total FRA score (r = .59, p = .001). Notably, perceived fitness for duty was poorly correlated with fatigue levels as measured by the FRA (r < .01). Conclusions The results of this study contribute to a very limited body of research on fatigue among air medical providers. Specifically, the study contributes to the knowledge about the construct validity of the Flight Risk Assessment, which can be used to evaluate fatigue among air medics. Further analysis can assist in determining appropriate cutoff scores to inform time-out policies for medics.
