University students' sleep during the COVID-19 pandemic in the State of Hawai'i.

Objectives: This study assessed undergraduates' sleep in Hawai'i during the COVID-19 pandemic and whether demographic characteristics, health locus of control, substance use and campus features related to sleep outcomes. Implications are considered for programs to support students' sleep and health during pandemic conditions. Participants: About 1,288 undergraduate students from six universities in Hawai'i. Methods: Surveys assessing sleep, emotional wellbeing, ethnicity, body mass index, locus of health control, and substance use. Results: Students' reported increased sleep time but decreased sleep quality during the pandemic. Sleep disruption related to anxiety, depression, ethnicity, substance use, BMI, health locus of control, class rank, and whether students lived at home. All campuses were associated with disrupted sleep, regardless of size, location, religious affiliation, term structure, or method of instruction. Conclusions: In response to public health crises, such as the COVID-19 pandemic, all Hawai'i universities should screen students for sleep disruption, emotional adjustment, social isolation and substance misuse. Programs to promote sleep and behavioral health appear particularly warranted for graduating seniors, Pacific Islanders, students with high BMI, and students who commute to college.

Effects of a Single Concussion During the School Year on the Academic Performance and Neuropsychological Functioning of High School Athletes.

There are very few studies examining the effects of sports-related concussion (SRC) on objective measures of school performance, such as grades or test scores. In this research, the grade point averages (GPAs) and scores of the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) of athletes who sustained an SRC during the school year were compared with those of athletes who did not have an SRC. Multivariate analysis of variance (MANOVA) revealed a significant linear decline in GPA of both groups across the school year, but indicated no difference in the GPA decline between the concussion and no concussion groups. The GPAs of the concussion and no concussion groups were not significantly different across the school year. Finally, no differences were found between the pre- and post-concussion ImPACT scores of the concussed athletes. This study found that an SRC during the school year did not affect the academic performance or neurocognitive test scores of high school athletes.

ImPACT Normative Data of Ethnically Diverse Adolescent Athletes.

OBJECTIVE: The aim of this research was to develop preliminary norms for the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) administered to a large sample of adolescent athletes from diverse ethnic backgrounds. DESIGN: A retrospective records review. SETTING: Middle and high school athletic departments. PARTICIPANTS: A total of 5741 male and female adolescent athletes in Hawaii, aged 13 to 18 years, in grades 9 to 12 were included in the study. INDEPENDENT VARIABLES: Age, sex, ethnicity, and sport. MAIN OUTCOME MEASURES: ImPACT Composite scores (Verbal Memory, Visual Memory, Visual Motor Speed, Reaction Time, and Impulse Control) and Total Symptom score from baseline testing. RESULTS: The results indicated statistically significant differences between age and sex groups, as well as between ethnic and sport groups. CONCLUSIONS: The findings support the continued use of stratified norms for age and sex for ethnically diverse adolescent athletes. Comparisons of ethnic and sport groups deserve further investigation. When baseline scores are not available for postconcussion comparison, present observations tentatively support the cautious use of standard ImPACT norms with ethnically diverse athletes.

Role of Native Language in Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) of Youth Athletes.

OBJECTIVE: The aim of this research was to examine the role of native language in the performance of youth athletes on a computerized neuropsychological test battery, the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT). METHOD: The study compared the baseline test scores of 5545 participants whose native language was English versus 195 whose native language was not English. The mean age of the participants was 15.06 years. RESULTS: A multivariate analysis of variance revealed no differences in the five ImPACT Composite scores of the two language groups. CONCLUSION: Contrary to prior research, one cannot simply expect that non-native English speakers will do more poorly on ImPACT than native English speakers. Further research on the use of ImPACT with other non-native English-speaking youth athletes is recommended.

Use of ImPACT to diagnose minimal hepatic encephalopathy: an accurate, practical, user-friendly internet-based neuropsychological test battery.

BACKGROUND AND AIMS: An effective, user-friendly neurocognitive test to diagnose minimal hepatic encephalopathy (MHE) is needed. Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) is a brief, validated, Web-based, neuropsychological test battery resulting in four composite scores [Verbal Memory (VrbM), Visual Memory, Visual Motor Speed (VMS), Reaction Time (RT)]. We compared ImPACT to traditional paper-and-pencil tests in patients at risk for MHE versus controls. METHODS: Ninety cirrhotic patients with no history of overt hepatic encephalopathy were compared with 131 controls on standard psychometric tests (SPT) [Trail Making Test-A, Trail Making Test-B, Digit Symbol Test], 4 ImPACT composite scores, and the Sickness Impact Profile (SIP). MHE+ was defined by a score 2 SD below the normative mean on at least one of the SPT. ImPACT (ImP+) scores of patients were defined as 2 SD from the control mean. RESULTS: Cirrhotic patients scored more poorly than controls on 3/4 of ImPACT scores: VrbM (78.88 vs. 71.37, p<0.001), VMS (26.47 vs. 22.68, p<0.001) and RT (0.89 vs. 1.00, p<0.01), as well as on all 3 SPT. Of the 90 cirrhotics, 16 (18%) were MHE+, who performed more poorly (p<0.001) than patients without MHE on VrbM (58.13 vs. 74.19), VMS (16.77 vs. 23.95) and RT (1.24 vs. 0.95). Of the 90 cirrhotics, 25 (27.8%) were ImP+. MHE+ and ImP+ patients had increased SIP scores versus controls (p<0.001). CONCLUSIONS: Compared to paper-and-pencil testing, ImPACT provides a brief, user-friendly, neuropsychological evaluation of MHE. ImPACT could become a new standard for MHE diagnosis.

Comparison of MMPI-2 validity scales among compensation-seeking Caucasian and Asian American medical patients.

Validity scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) are widely used for the detection of exaggerated psychological complaints, although little is known about the results of these scales with racial or ethnic minority individuals. Five validity scales derived from the MMPI-2, including the F Scale, the Back Infrequency Scale, the Symptom Validity Scale, the Infrequency-Psychopathology Scale, and the Dissimulation Scale-MMPI-2, were evaluated in 157 medical patients-109 Caucasian Americans and 48 Asian Americans. All patients were involved in personal injury litigation or seeking compensation for alleged psychological conditions. Analyses of variance (ANOVAs) conducted on the five validity scales revealed no significant group effects for race. The results were consistent with the limited available data on the MMPI-2 validity scales with minority group samples. Further research with other racial minorities, including relevant extra-test criteria for malingering, is encouraged.
