Abstract Objective This study provides normative data on the SCAT5 Cognitive Screening, establishes test-retest reliability, and creates clinically relevant cut points for low performance. Method The multisport baseline sample was composed of 727 uninjured college athletes (52% female) at a Division I university who were administered the SCAT5 before the 2017–2018 season. Descriptive statistics, including base rates of low performance, were calculated for SCAT5 indices. Repeat baseline testing was completed by 325 athletes (48% female) at 1 year (days M = 352.56;SD = 56.03) who were included in the test-retest reliability and practice effect analyses. Reliable change indices were calculated. Results Descriptive statistics for SCAT5 were computed for both baselines (Baseline 1: SAC total M = 35.15,SD = 4.93; immediate recall total M = 20.01,SD = 3.46; delayed recall total M = 6.43,SD = 1.75). A difference in descriptive statistics and practice effects by sex on the SCAT5 Cognitive Screening has been demonstrated (Bailey, Meyer, Tangen et al., under review). For female athletes, the 1st administration cutoff scores for abnormal performance (<10th%ile) included SAC total score = 33, immediate recall score = 18, and delayed recall score = 6. For male athletes, the 1st administration cutoff scores for abnormal performance (<10th%ile) included SAC total score = 30, immediate recall score = 17, and delayed recall score = 5. Test-retest reliability of the SAC was similar to previous versions but varied by sex. Reliable change indices (RCI) were created with cut points for significant change. Conclusions The present study provides clinically relevant normative data for the SCAT5 Cognitive Screening. Cut points for low performance on both reliable chance indices (RCIs) and normative performance reflected meaningful sex differences that could influence clinical interpretation.

Objective: Moving Shapes paradigm is a test that evaluates intentionality as a theory of mind (ToM) component. This study aimed to assess the normative data and reliability of this test in a community sample of 9-11-year-old children. Method: A total of 398 children aged between 9 and 11 years were recruited from mainstream elementary schools through a random cluster sampling. All participants were evaluated using the Moving Shapes paradigm. To evaluate test-retest reliability, the test was administered again after 2-4 weeks. Results: The intentionality mean score was 29.70 (+5.88) out of 60. There was no significant difference between girls and boys in test scores. Age was not significantly related to the paradigm variables scores. Ten percent of the participants achieved the scores below 22, and 10% above 37. Cronbach’s Alfa was 0.40 for the intentionality score. The test-retest reliability was fair to good (0.43 - 0.79) for different groups of animations. The inter-rater agreement was 80%. Conclusion: The study found that the Moving shapes paradigm is a reliable instrument to evaluate intentionality in normal school-aged children.

AbstractSevere Acute Respiratory Syndrome Coronavirus 2 infection causes coronavirus disease 2019. COVID-19 was an unknown infection that reached pandemic proportions in 2020 and has shown to bring long-term negative consequences. Here, we used a case-control design to investigate the performance of relatively young people recovered from COVID 19 in objective neuropsychological tests. We found significant differences between groups for all measures of the ROCFT with a large difference in the copy, a moderate difference in immediate recall, and a large difference in delayed recall. No significant differences were found for the measures from all the other five neuropsychological tests used.About one quarter of COVID 19 patients were below the 10th percentile according to normative data.

Test Retest Reliability

Background: The acoustic stapedial reflex (ASR) test provides useful information about the function of the auditory system. While it is frequently used with adults and children in a clinical setting, its use with young infants is limited. Presently, there are few data for neonates and inadequate research into the test-retest reliability of the ASR test. Purpose: This study aimed to establish normative data and evaluate the test-retest reliability of the ASR test in healthy neonates. Research Design: A cross-sectional experimental design was used to establish ASR normative data and assess the test-retest reliability of ASR thresholds obtained from healthy neonates. Study Sample: Sixty-eight full-term neonates with mean chronological age of 2.5 days (SD = 1.8 day), who passed the automated auditory brainstem response, transient evoked otoacoustic emission, and high frequency (1 kHz) tympanometry (HFT) tests. Data Collection and Analysis: One randomly selected ear from each neonate was tested using TEOAE (transient evoked otoacoustic emission), HFT, and ASR tests using a 1 kHz probe tone. ASR thresholds were elicited by presenting pure tones of 0.5, 2, and 4 kHz and broadband noise (BBN) separately to the test ear in an ipsilateral stimulation mode. The ASR procedure was repeated to acquire retest data within the same testing session. Descriptive statistics, χ2, and analysis of variance with repeated measures tests were used to analyze ASR data. Results: All neonates exhibited ASR when stimulated by tonal stimuli or BBN. The mean ASRTs (acoustic stapedial reflex thresholds) for the 0.5, 2, and 4 kHz tones were 81.6 ± 7.9, 71.3 ± 7.9, and 65.4 ± 8.7 dB HL, respectively. The mean ASRT for the BBN was estimated to be smaller than 57.2 dB HL, given the limitation of the equipment. The 95th percentiles of the ASRT were 95, 85, 80, and 75 dB HL for the 0.5, 2, and 4 kHz and BBN, respectively. The test-retest reliability of the ASR test for all stimuli was high, with no significant difference in mean ASRTs across the test and retest conditions. Test-retest differences were within 10 dB for more than 91% of ASRT data across all stimuli. There was a slight trend of ASRTs being more repeatable in the medium ASRT range than in the higher or lower range. Conclusions: This study demonstrated that ASRTs obtained from healthy neonates were highly repeatable across test and retest sessions. Given the availability of normative data and the high test-retest reliability, the ASR test will be useful as a diagnostic tool in a battery of tests to evaluate the auditory function of neonates.

The Suinn Test Anxiety Behavior Scale was administered to both graduate and undergraduate students to reassess earlier findings (Suinn, 1969). The primary purpose of this study was to provide normative data for graduate students ( N = 153). Such information does not appear in Suinn's 1969 article. Means, standard deviations, and percentiles are reported for each sex, as well as for the total graduate sample. Females reported significantly higher test anxiety. Test-retest reliability over a 6-wk. interval was .73. In general, the findings for the graduate students were similar to Suinn's findings for undergraduates.

Abstract Objective The principal goal of this study was to produce adjusted normative data for European Portuguese native speakers from Portugal on 2 neuropsychological tests widely used to assess learning and memory: the Hopkins Verbal Learning Test-Revised (HVLT-R) and the Rey–Osterrieth Complex Figure Test (ROCF). Method The study included 300 individuals aged 18–92 years (M = 50.4, SD = 21.2), who had educational backgrounds ranging from 3 to 25 years (M = 10.4, SD = 5.2). Results Age, education, and sex were significantly associated with HVLT-R and ROCF performance. These demographic variables accounted for 61% of the variance in HVLT-R total recall, 54% in HVLT-R delayed recall, 18% in HVLT-R recognition, 55% in ROCF copy, and 39% in ROCF immediate recall. Conclusions The normative data are presented as regression-based algorithms to adjust direct and derived test scores for age, education, and sex. This study provides a calculator of normative data derived from the results of the regression models.

Abstract Objective Digital, remote, cognitive assessment has become crucial for efficient screening of patients cognitive concerns. The Boston Cognitive Assessment (BoCA) is a brief, digital, global screening instrument that can be administered both in-office on a laptop, or remotely from patients’ homes. Potential differences in performance from completing the BoCA in-office versus completing it at home remain uninvestigated. As such, this study aimed to compared performances across these settings among demographically and cognitively matched patient samples. Method Data from 35 cognitively healthy participants who completed the BoCA (18 administered in-office; 17 remotely administered) were retroactively collected; groups were matched by age, education, gender, ethnicity, and global cognitive functioning based on their scores on a separate screening instrument. Overall BoCA scores (total = 30) as well as performance on the eight BoCA subscales (Immediate Recall, Delayed Recall, Verbal Reasoning, Visuospatial Reasoning, Executive Functions, Attention, Mental Math, and Orientation) were compared using nonparametric testing. Results A Contingency analysis and an independent samples Mann–Whitney U test confirmed the demographic and cognitive similarities between the two groups. Comparisons of BoCA scores revealed no differences in total scores or any of the BoCA subscales between those who completed the BoCA in-office and those who completed it remotely. Conclusion Results from the present study suggest that performance on the BoCA is not influenced by one’s environment at the time of administration. This further adds to the utility of the BoCA as a remote, self-administered, global screening instrument, and may support its adoption in settings where serial screening is indicated.
