Ansiedad durante pruebas de evaluación académica: influencia de la cantidad de sueño y la agresividad

The situation of academic evaluation has often been studied in relation to emotional alterations such as anxiety, stress or even fear. Possibly, aggressiveness may be another variable present in these situations. Aggressiveness seems to be present in different teaching activities as well as in all levels of the educational context, showing even more clearly in students with academic difficulties and especially when exposed to stressful situations. Various classical investigations have indicated for some time now that physical and verbal aggressiveness is more frequent in men than in women, and also more intense. The execution of academic tests is perceived as an aversive situation and often even as a threat, which may explain why they would be the cause of anxiety or stress. In fact, an intense emotional alteration could be present in nearly 25% of the students during the examination procedure; furthermore, exams are the most frequent evaluation method used in all educational levels. According to some studies, women seem to show higher levels of resources for coping with stressful situations, which would also be applied to circumstances of academic evaluation. Nevertheless, again in relation to gender differences, higher levels of anxiety have been found in women in comparison to men among university students before exams are carried out. In this situation the presence of aggressiveness does not seem to be clear. Although in the psychological environment there is no doubt of the negative effect which sleep deprivation has on different types of performance, we have observed with some frequency that university students tend to reduce sleep time days before an exam. The studies centred in the population of university students’ quality of sleep have found that it quite often drops during this period. Thus, for example, in normal circumstances (not during exam periods), poor sleep quality can be found in approximately 30% of the university students. With this, we may suppose that the quality and the quantity could be even worse in exam periods. The quality of sleep has been studied frequently and also in relation to difficulties and psychological alterations. In the case of test anxiety, the correlation with the reduction of the quantity of sleep the previous night seems to be positive. Although multiple investigations have centred on the disrupting role that anxiety plays on the performance of exams, not many have focused on the relation between test-anxiety and aggressiveness in that situation, and even less so in circumstances of reduction of sleep hours. In the present work, we intend to determine first the possible presence of aggressiveness during the execution of exams in a sample of university students. At the same time, it was of our interest to establish a possible relation between sleep hours and the level of aggressiveness in that situation, keeping in mind that many students reduce sleep hours during this time, and specially the night before an exam. A second objective is to determine if different levels of aggressiveness may be related to different levels of test-anxiety. Thirdly, we try to seek differences between men and women’s levels of aggressiveness while test circumstances, differences in aggressiveness in function of different age levels, as well as in function of different amount of time dedicated to sleep. In this study, 143 students aged 19-48 participated. The average age was 21.67, with a 3.79 standard deviation. Forty-two of the participants were men, 98 women and three of them did not consign their gender. All of them participated in the study just before beginning the execution of a final test in diverse subjects when they were already seated in the classroom. Aggressiveness was assessed with the reduced Spanish version of the Aggression Questionnaire (AQ). For the anxiety assessment, the Spanish version of the Spielberger State-Trait Anxiety Inventory (STAI) was used, applying only the state scale. Additionally, participants were asked to note the hours of sleep they had had the previous night. The collection of data was carried out during a final exam, which assigned the final qualification in that subject. Several studies have shown the poor sleep quality in university students, being this significant characteristic a variable with possible and important implications in their quality of life, health, or even in their performance. Our data show that the average number of hours of sleep on the previous night to an exam was 6.43 (S.D.=1.55), which indicates that the tendency to reduce the hours of sleep in this situation is a frequent habit among the university students being analyzed. Our descriptive results indicated that the levels of aggressiveness are not too high, although a certain degree does exist before the evaluation tests. The correlation analysis carried out indicates that having less hours of sleep the previous night is not associated with a higher level of aggressiveness [r=-.066 (p=.437)]. Nevertheless, when the sample
