In the present study, we first determined the prevalence of academic procrastination among the students of medicine. Based on the results, overall 29.25% of the students were always or nearly always procrastinators; in other words, the results showed that a high percentage of the students tended to delay their academic tasks; this is in the same line with the results of other studies (
7,
11-
13,
31). However, the majority of other studies have reported a higher prevalence. In the present research, 26.6% of the students reported procrastination always or nearly always in writing a term paper, while Ozer et al. (
15) and Solomon and Rothblum (
12) studies reported 30% and 46%, respectively. About 30% of the students nearly always or always postponed studying for their exams; in these two above-mentioned studies, this rate was reported as 33% and 27.6%, respectively.
Moreover, 21.8% of the students nearly always or always postponed keeping up with weekly reading. The prevalence of this dimension in SUMS was lower than those of Ozer et al. (
15) and Solomon and Rothblum (
12) studies (30% and 30.1%, respectively). Also, the results revealed that 28% of the medical students nearly always or always postponed performing administrative tasks; this is much higher than the rates reported by Ozer et al. and Solomon and Rothblum (10% and 10.6%, respectively) (
12,
15).
As to attending the meetings, the results showed that 26.1% of the students were nearly always or always procrastinators; this has been reported to be lower in other studies. Finally, the results showed that 43% of the medical students were nearly always or always procrastinators as to performing academic tasks in general; in Ozer et al. (
15) and Solomon and Rothblum (
12) studies, this has been reported as 5% and 10.2%, respectively.
Furthermore, the results showed that there was a significant negative relationship between medical students’ academic procrastination and academic achievement; this result is in the same line with those of other previous studies (
13,
23,
24,
26,
29,
32). Therefore, it is likely that procrastination results in low success and achievement since in case a student cannot succeed in writing term papers or study for the exam, he/she will get low scores. Moreover, the relationship between procrastination and academic achievement can be explained by the mediating role of other academic and motivational variables. For example, the findings of some studies indicated that procrastination affected one’s academic achievement through influencing the individual’s rational beliefs in studying and academic satisfaction (
29). In other words, students with high levels of procrastination are most probably unsatisfied with their academic life due to working under the limitation of time. Also, these individuals experience more stress and anxiety, which can, in turn, negatively affect their performance.
The results of other research in educational contexts have revealed that the lack of satisfaction with academic life and stress are associated with low performance (
29) since procrastinating individuals like to work under the pressure of time (
33). Tice and Baumeister pointed out that working under the pressure of time can lead to stress and it adversely affects the performance (
34). Research has shown that individuals who tend toward procrastination tend to have a low performance. Some researchers believe that the low level of performance in procrastinating students results from their low self-efficacy (
35). Students with low levels of self-efficacy are most probably afraid of accepting and doing the assignments, avoid working, postpone it, and give it up soon. Also, another reason for the low achievement of procrastinating individuals is, as shown by some studies, that these people possess low levels of self-regulating and metacognitive learning strategies (
5,
6,
36).
Some researchers have defined procrastination as a failure in self-regulation performance (
37), which leads to the inability to do or finish their academic assignments and tasks. Accordingly, the researchers believe that self-regulated learning strategies have a facilitating role in the process of learning (
38) and the students with a variety of these strategies learn more and perform better than their peers who are not skillful in the use of these strategies (
32).
It was also found that there was a significant difference in procrastination between male and female students; male students practiced more procrastination than their female peers. The results of other studies on the relationship between gender and procrastination are contradictory. Some studies have indicated that there is no significant difference in procrastination between male and female participants (
39). Some other researchers have revealed that girls are more procrastinators in their tasks (
12), but the results of the present study were in the same line with those showing more procrastination among males (
15,
28,
40). This discrepancy can root in cultural differences. It can be concluded, as shown in other studies, that girls are better than males in self-regulated learning strategies and self-efficacy (
41). Also, the results have shown a negative relationship between self-regulated strategies and academic procrastination; students who use these strategies more practice less procrastination in their academic tasks (
6).
Moreover, female students act more competitively than male ones in academic contexts and are more motivated to get higher grades; therefore, they have less academic procrastination. Some believe that obtaining lower grades is more fearful for girls than for boys, so they try to avoid it. Therefore, it can be said that fear of failure acts as a mechanism for the lower level of procrastination in girls.
According to the results, there was a significant difference between the students who lived in the dormitory and those who did not in the level of academic procrastination; in other words, those residing in the dormitory were more procrastinators than those who did not. The atmosphere of the dormitory causes the students to spend more time on pastime and hobbies together; also, they spend much of their time on the Internet and social networks; this leads to postponing their academic assignments. It is obvious that the dormitory context, unlimited access to the Internet, and their hobbies lead to negative outcomes as to their education and performance.
Finally, it was shown that there was a difference in academic procrastination among the students in different periods of their university studies; with an increase in the years of education, the students became more procrastinator. However, the differences were not significant. Some researchers have reported that with an increase in the years of education, the students’ motivation decreases since motivation is negatively associated with procrastination; the less the students’ motivation, the more the procrastination behaviors (
42). Furthermore, when medical students enter higher levels of their education, they get more involved in their clinical activities and practically have less chance of following their academic duties.
Generally speaking, the results revealed that a considerable number of students practice procrastination in all dimensions. Notably, those who practiced more procrastination had poorer academic performance; thus, it is suggested that all educational authorities take this issue into account.
In the present research, we used a self-report questionnaire, which might have involved some bias. Moreover, the data were collected from the medical students studying at Shiraz University of Medical Sciences; this limits the generalizability of the results to the students of other universities and other majors. Also, this was a cross-sectional research study in which the data were collected in a specific time period. Therefore, it is suggested that further research be carried out longitudinally to determine the level of procrastination behaviors among the students. Despite the mentioned limitations, it is believed that the current research increases the authorities’ insight into the studied issue in the student and medical school contexts.
5.1. Conclusions
The findings of this study showed that procrastination behaviors are considerably seen among medical students, especially in writing term papers and doing assignments. The other important finding of this study was that there was a negative correlation between the students’ procrastination behaviors and their academic success. It is concluded that procrastination can negatively impact the students’ academic performance and that gender and living at home or dormitory can affect the students’ procrastination behaviors.
