Previous studies have shown that study addiction is related to worse academic performance among music academy students as well as in the general population of students, suggesting that excessive examination stress may impair their performance on exams. The aim of this study was to investigate the relationship between the newly developed concept of “study addiction” and examination stress among students of music academies. Study addiction has been defined within the framework of theory and research on work addiction as a potential behavioral addiction. A cross-sectional correlational study was conducted, with a sample of 132 students of music academies in Poland. The Bergen Study Addiction Scale, assessing seven core addiction symptoms related to studying, was administered together with a commonly used measure of personality and single-item measures of examination stress and learning engagement. Multiple hierarchical regression analysis showed that study addiction was related to higher examination stress above and beyond personality traits. What is more, while study addiction showed a positive relationship with examination stress, learning engagement showed a negative association with examination stress. The results suggest that, among music academies students, study addiction is related to higher stress during exams and that study addiction and learning engagement are different constructs. Taking into account the relationship of study addiction with higher stress in situations of being evaluated, future studies are warranted that would link study addiction to music performance anxiety, which is one of the most widely studied phenomena in the psychology of music.

Introduction: Plant extracts rich in phenolic compounds may modify the stress level. The aim of this project is to investigate whether freeze-dried rosehips (Rosa rugosa), taken orally by students, affect cortisol concentration before and after a highly stressful exam. Materials and methods: The double-blind study included healthy volunteers recruited from medical and health sciences students. Participants in the study group took capsules containing 400 mg of freeze-dried ground rosehips for five consecutive days preceding the exam (stressor). At that time, the control group was taking a placebo (120 mg of glucose). Participants completed a questionnaire on their gender, lifestyle, medical history, physical activity, diet, stimulants, medications and dietary supplements. Saliva samples for determining the level of cortisol in saliva were taken three times: in the morning before the beginning of the experimental phase, in the morning before the stressor, and one hour after the stressor subsided. The level of cortisol in saliva was determined using ELISA. Results: It was found that taking freeze-dried rosehips for five days significantly reduced the level of cortisol in students after the exam compared to the placebo group. There were no differences in the level of cortisol before the exam, regardless of the preparation taken. No other analyzed factor influenced the concentration of the stress hormone in students. Conclusions: Freeze-dried rosehips can help reduce the effects of stress.

Wprowadzenie: Ekstrakty roślinne bogate w polifenole mogą modyfikować poziom stresu. Celem projektu było zbadanie, czy liofilizowane owoce róży (Rosa rugosa) przyjmowane doustnie przez studentów wpływają na poziom kortyzolu przed i po silnie stresującym egzaminie. Materiał i metody: Badanie o charakterze podwójnie ślepej próby objęło zdrowych ochotników rekrutowanych pośród studentów kierunków medycznych. Uczestnicy w grupie badanej przyjmowali kapsułki zawierające po 400 mg liofilizowanych mielonych owoców róży przez pięć kolejnych dni poprzedzających egzamin (stresor). W tym czasie grupa kontrolna przyjmowała placebo. Uczestnicy wypełnili ankietę dotyczącą ich płci, stylu życia, historii chorób, aktywności fizycznej, stosowanej diety, używek, leków i suplementów diety. Próbki śliny do oznaczenia poziomu kortyzolu zostały pobrane trzykrotnie: rano przed rozpoczęciem fazy eksperymentalnej, rano przed stresorem oraz godzinę po ustąpieniu stresora. Poziom kortyzolu w ślinie oznaczono metodą immunoenzymatyczną. Wyniki: Stwierdzono, że przyjmowanie liofilizowanych owoców róży przez pięć dni istotnie zmniejsza poziom kortyzolu u studentów po egzaminie w porównaniu z grupą przyjmującą placebo. Nie wykazano różnic w poziomie kortyzolu przed egzaminem niezależnie od przyjmowanego preparatu. Żaden inny analizowany czynnik nie wpływał na stężenie hormonu stresu u studentów. Wnioski: Liofilizowane owoce róży mogą pomagać w osłabieniu skutków stresu.
