“…The advantage of administration of the CogState in a clinical setting is that a supervisor can help participants understand the task during the practice session. Participants assessed in an unsupervised research setting may be more easily distracted, show sub-optimal effort and motivation, or may have lower scores due to inadequate understanding of the task [37]. However, the CogState is increasingly administered in an unsupervised or home setting [13, 37, 38], making it less labor-intensive and less costly than a supervised clinical setting and standard pencil and paper testing.…”

Comparison of cognitive functioning as measured by the Ruff Figural Fluency Test and the CogState computerized battery within the LifeLines Cohort Study

BackgroundThe Ruff Figural Fluency Test (RFFT; a pencil and paper test) and the CogState (a computerized cognitive test battery) are well-validated and suitable tests to evaluate cognitive functioning in large observational studies at the population level. The LifeLines Cohort Study includes the RFFT as baseline measurement and incorporated the CogState as replacement for the RFFT at follow-up. It is unknown how these two tests relate to each other. Therefore, the aim of this study is to examine the correlation between the RFFT and the CogState and the impact of demographic characteristics on this association.MethodsA subcohort of the LifeLines Cohort Study, a large population based cohort study, participated in this study. Correlations between the RFFT and six subtasks of the CogState were examined. Subgroup analyses were performed to investigate the influence of age, education, and gender on the results. With sensitivity analyses we investigated the influence of computer experience and (physical) impairments.ResultsA total of 509 participants (mean age (SD): 53 years (14.6); range 18–87 years) participated in this study. All correlations between the RFFT and the CogState were statistically significant (except for the correlation between the RFFT error ratio and the CogState One Back Task), ranging from -0.39 to 0.28. Stratifying the analyses for age, education, and gender did not substantially affect our conclusions. Sensitivity analyses showed no substantial influence of level of computer experience or (physical) impairments.ConclusionsCorrelations found in the present study were only weak to moderate, indicating that cognitive functioning measured by the RFFT does not measure the same components of cognitive functioning as six subtasks of the CogState. Computerized testing such as the CogState may be very well suited for large cohort studies to assess cognitive functioning in the general population and to identify cognitive changes as early as possible, as it is a less time- and labor intensive tool.

“…[35,37] Moreover, Cogstate has been shown to be a sensitive indicator of early cognitive deficits. [35] Cogstate performance has been found to be similar in supervised and unsupervised settings, [39] and the feasibility and utility of an unsupervised, online administration of the brief battery has been demonstrated in a large population-based sample. [34] Internet speed does not affect Cogstate performance data because the Cogstate tasks are first loaded via the Internet and then run locally on a participant’s computer.…”

Posttraumatic stress disorder symptoms and cognitive function in a large cohort of middle-aged women

et al. 2017

Background Posttraumatic stress disorder (PTSD) has been linked to cognitive decline, but research in women is generally lacking. We examined whether trauma and elevated PTSD symptoms were associated with worse cognitive function in middle-aged civilian women. A secondary objective was to investigate the possible role of depression in the relation of PTSD symptoms to cognitive function. Methods The sample comprised 14,029 middle-aged women in the Nurses’ Health Study II. Lifetime trauma exposure, lifetime PTSD symptoms, and past-week depressive symptoms were measured in 2008. Cognitive function was measured in 2014–2016 using the Cogstate Brief Battery, a self-administered online cognitive battery that assesses psychomotor speed, attention, learning, and working memory. We used linear regression models to estimate mean differences in cognition across PTSD symptom levels. Results Compared to no trauma, elevated PTSD symptoms consistent with probable PTSD (i.e., 4+ symptoms on a screening questionnaire) were associated with worse performance on psychomotor speed/attention (b=−0.08 standard units, p=.001) and learning/working memory (b=−0.09, p<.001) composites, after adjusting for socio-demographics. Although attenuated, associations remained significant when adjusted for depressive symptoms and other cognitive risk factors. We found the strongest associations among women with comorbid probable PTSD and depression. Conclusions PTSD symptoms were negatively related to measures of psychomotor speed/attention and learning/working memory in middle-aged women. Our study adds to a growing literature that suggests that mental disorders are associated with worse cognitive function over the life course.

“…The CogState standardized battery [http://cogstate.com/computerized-tests/cognitive-tests/battery] was chosen due to its high test-retest reliability and negligible practice effects in healthy individuals across different exam settings (Cromer et al, 2015; Falleti et al, 2006). Task performance (speed or accuracy as per Maruff et al, 2009) was contrasted pre- vs. post-training within subjects using paired t-tests.…”

In this pilot study, we examined training effects of a computerized working memory program on resting state functional magnetic resonance imaging (fMRI) measures in children with neurofibromatosis type 1 (NF1). We contrasted pre- with post-training resting state fMRI and cognitive measures from 16 participants (nine males; 11.1±2.3 years) with NF1 and documented working memory difficulties. Using non-parametric permutation test inference, we found significant regionally specific differences (family-wise error corrected) in two of four voxel-wise resting state measures: fractional amplitude of low frequency fluctuations (indexing peak-to-trough intensity of spontaneous oscillations) and regional homogeneity (indexing local intrinsic synchrony). Some cognitive task improvement was observed as well. These preliminary findings suggest that regionally specific changes in resting state fMRI indices may be associated with treatment-related cognitive amelioration in NF1. Nevertheless, current results must be interpreted with caution pending independent controlled replication.

Comparison of Cognitive Performance on the Cogstate Brief Battery When Taken In-Clinic, In-Group, and Unsupervised

Abstract: These results suggest that cognitive testing with the CBB in alternate settings can provide valid cognitive data comparable to data obtained during individually supervised testing.
