Expression of anger in university students according to perceived quality of sleep.

OBJECTIVE: We analyzed the expression of anger according to the perceived quality of sleep in university students. METHODS: A total sample of 1252 students participated in the study, with an average age of 23.58 years. Using an ex-post facto design and an incidental sampling procedure, the Pittsburgh Sleep Quality Index and the State-Trait Anger Expression Inventory-2 were applied. RESULTS: Students with poor sleep quality (PSQI scores> 5) scored higher on the subscales of STAXI-2, showing higher risk of obtaining superior values in Trait Anxiety [OR=1.90] and in the Index of Expression of Anger [OR=1.56], but not in Internal Control of Anger. CONCLUSIONS: There appears to be a marked relationship between quality of sleep and anger, and it is suggested that sleep hygiene programs can help to reduce the negative consequences of poor sleep quality in terms of health and academic performance in students.

Level of physical activity and sleep characteristics in university students.

INTRODUCTION: The aim of the present study was to identify the subjective quality of sleep, the chronotype, the frequency of nightmares and the propensity for nightmares in university students depending on whether they are sufficiently physically active (SPA) or insufficiently physically active (IPA). METHODS: The study involved 855 students (55.67% women) of which 38.01% are IPA. Evaluations were conducted using the Brief Physical Activity Assessment Tool, the Pittsburgh Sleep Quality Index, the Nightmare Frequency Scale, the Nightmare Proneness Scale and The Composite Scale of Morningness. RESULTS: IPA students showed a greater probability of presenting [OR=2.02] poor sleep quality (> 5 PSQI points) compared with SPA students (p<.001). The IPA participants showing a greater probability [OR=3.70] of having an evening chrontoype (p<.001), report a higher frequency of nightmares (p<.001) and a greater propensity for nightmares (p<.001) compared with the SPA participants. In terms of propensity for nightmares an interaction was found between gender and level of PA (F (3,843)=11.360, p=.001). CONCLUSION: The possibility of implementing strategies to increase the level of PA among university students should be explored, as well as offering sleep hygiene programs that are effective when used in brief sessions.
