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

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. About 1,288 undergraduate students from six universities in Hawai'i.

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.

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.

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.

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.

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.
