Test Anxiety and Poor Sleep an Active Sequence by Jayashree on April 29, 2021 at 10:13 PM the International Journal of Behavioural Medicine published new research by university of Kanas that explained students who drop out, withdrew from classes and with poor grades had a active kind of biopsychosocial process between the test anxiety and sleeping habit. , "We were interested in finding out what predicted students' performance in statistics classes -- stats classes are usually the most dreaded undergrad class," said lead author Nancy Hamilton, professor of psychology at KU. The researchers were more interested to know about the link between sleep, anxiety and test performance, so they surveyed 167 students enrolled in statistics by using electronic battery of measures and filled out Sleep Mood Study Diaries to know about their sleep quality, anxiety levels and test scores.
