Different kinds of psychological distress have been identified for students in the health field, especially in the medical school.


To estimate the prevalence of mental suffering among medical students in the Southeastern Brazil and asses its association with social support.


It is a cross-sectional study. Structured questionnaires were applied for students from the 1st up to the 6th years of the medical school of Universidade Estadual Paulista "Júlio de Mesquita Filho", assessing demographic variables related to aspects of graduation and adaptation to the city. Psychological suffering was defined as a common mental disorder (CMD) assessed by the Self Reporting Questionnaire (SRQ-20). Social support was assessed by the social support scale of the Medical Outcomes Study (MOS). The association between the outcome and explanatory variables was assessed by the χ2 test and Logistic Regression, for the multivariate analyses, using p < 0.05.


The response rate was of 80.7%, with no differences between sample and the population regarding gender (p = 0.78). The average age was 22 years old (standard deviation - SD = 2.2), mainly women (58.2%) and students who were living with friends (62%). The prevalence of CMD was 44.9% (95%CI 40.2 - 49.6). After the multivariate analyses, the explanatory variables that were associated with CMD were: feeling rejected in the past year (p < 0.001), thinking about leaving medical school (p < 0.001) and "interaction" in the MOS scale (p = 0.002).


The prevalence of CMD among medical students was high and insufficient social support was an important risk factor. Our findings suggest that interventions to improve social interaction among those students could be beneficial, decreasing the prevalence of CMD in this group.

Different forms of mental suffering have been prevalent among students in the health field1. Even though it is not exclusive for medical students2 , 3, there is clear prevalence of studies about this population4. Several aspects have been mentioned as risk factors for mental distress, from the psychodynamic mechanisms of the individuals who choose this field5 until factors related to the structure of the course6 , 7, or even the characteristics of the professional practice8 , 9.

Most studies conducted in Brazil with populations of medical students investigated distress in the form of the so called common mental disorders (CMD). According to Goldberg and Huxley10, the CMDs are usually found in the population and indicate a mental suffering condition. According to these authors, there is an interruption in the usual functioning of the subject, but this situation is not always associated to a psychiatric diagnosis by the standardized criteria, for instance, by the International Classification of Diseases (ICD-10) of the World Health Organization11. It is relevant to identify such disorders, once they can cause damage and functional inabilities as much as chronic mental disorders12, being possibly associated to other health issues13. Studying the CMD is also relevant because the use of psychiatric nosological categories has been proven to be inadequate outside the psychiatric context, in which non-specific forms of mental distress prevail14.

The prevalence of CMD in national studies has ranged from 20 to 44%, and individual and social15 - 19 characteristics have been pointed out as risk factors. Hidalgo et al.15, by using the Self-Reporting Questionnaire (SRQ-20), observed a positive association between insomnia and CMD, and found a 22.2% prevalence. Volcan et al.16 estimated a 20% prevalence for CMD, also using the SRQ-20, and spiritual well-being was demonstrated as a protective factor.

Facundes and Ludermir17 studied the prevalence of common mental disorder among students in courses of Physical Education, Nursing, Odontology and Medicine in Universidade de Pernambuco, trying to evaluate its association with characteristics of the teaching-learning process. They observed prevalence of 34.1%, being higher among students who felt overwhelmed with academic activities and referred having lived special situations in childhood and adolescence. In this study, no comparisons were made between students from different courses17. Souza and Menezes18 investigated stress among medical students at Universidade Federal do Ceará, using another screening instrument for CMD, the General Health Questionnaire (GHQ), and observed prevalence of "psychological disorders" of 35.4%, associated to the female gender and to students in the fifth semester of the course.

In the studies by Fiorotti et al.19 and Almeida et al.20, the prevalence of CMD was equally high. Almeida et al.20, in a study conducted with students from a medical school in Bahia, obtained CMD prevalence of 29.6%, which was independently associated with changes in the sleeping pattern, not having private transportation, not working and not performing physical activities. In the analysis by Fiorotti et al.19, the prevalence of CMD was of 37.1%, and the potential risk factors were: not receiving the necessary support and presenting difficulties to clarify any doubts in the classroom as a child or teenager.

Lima et al.21 observed high prevalence of mental distress (44%) among medical students from a college in the countryside of São Paulo, associated to the following factors: not receiving the necessary emotional support, having difficulties to make friends, reporting regular/poor school performance, and thinking of leaving the course. In the mentioned study, the evaluation for not receiving the necessary emotional support increased the risk for CMD six times, even after the adjustment for potential confusing factors. These findings, as well as the ones observed by Fiorotti et al.19, suggest that the presence of insufficient local support is an important factor that should be specifically studied.

For a while, studies have shown that the presence of social support is associated with better results concerning health in general22. However, there are not many studies about this subject among medical students. Rospenda et al.23 observed there was an association between social support and academic performance, but they did not investigate mental disorders. Sreeramareddy et al.24, in a study conducted in Nepal, identified that the search for emotional support was an important strategy to face stressful situations, among others used by the students. The authors emphasized the need for further studies on the subject, and they also pointed out to the relevance of interventions in teaching institutions in order to provide better stress management.

This study aimed at estimating the prevalence of CMD among medical students and studying the association between psychosocial support and the presence of disorders. In the country, there are studies indicating the high prevalence of CMD, but there are no analyses concerning the social support issue - which motivated this investigation. As hypotheses, the expectation was that the prevalence of CMD was around 20 to 45%, as in other investigations, and that the disorders were associated to insufficient social support.


This is a cross-sectional observational study of independent samples in the different years of the medical school at Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP). The school is located in Botucatu, São Paulo, a medium-sized city with about 120 thousand inhabitants. Most of the population is urban25. The target population were all of the students in the medical course at the time of data collection (n = 545). The inclusion criteria were: being regularly enrolled from the first to the sixth year of the medical course, attending classes on the day the instruments were being applied and consenting to participate in the research by signing the informed consent form. The application of the instruments occurred on dates that had been previously scheduled with the professors and in classes and disciplines that presented lower absence levels, except for those where tests were being applied.

A standardized, self-applicable questionnaire was used (available from the authors), which enabled to obtain data about the sociodemographic characteristics of the students and their respective families, such as gender, age, income, parents' schooling, among others. The questionnaire also had questions concerning adaptation to the city and frequency of visits to the families, since more than 90% of the students are not from the city where the college is located. The choice of variables to be included in the questionnaire considered the fact that they were pointed out as factors associated with CMD in previous studies, and because they were established as explanatory variables in this study, such as social support. So, the following structured and validated instruments were used.

Social Support Scale

In order to assess social support, the Social Support Scale (SSS) was used, which had been originally elaborated for the Medical Outcomes Study, and then translated and adapted to Portuguese26. The choice for SSS considered that it presented the adequate psychometric qualities in another study with similar characteristics: literate population and self-application27. The scale has 19 items that approach 5 functional dimensions of social support: material (provision of practical resources and material help); affective (physical demonstrations of love and affection); emotional (positive affection expressions, comprehension and feelings of confidence); positive social interaction (availability of people to have fun or relax with) and information (availability of people to obtain advice or guidance from), as described by Griep et al.27. Since the SSS does not have a previously established cutoff point, two categories were created and called "sufficient" and "insufficient" in order to assess the obtained scores in each of the scale domains. Therefore, median and interquartile intervals were used. Scores up to the first quartile were classified as "insufficient" support, and scores above the first quartile were classified as "sufficient" support.

Self-Reporting Questionnaire

The SRQ-20 does not provide a psychiatric diagnosis, but it enables the evaluation of general mental health conditions, such as anxiety, insomnia and other symptoms of mental distress, which have been called common mental disorders14.

This instrument has been widely used in studies with several populations14, and also medical students15 , 16 , 18 - 20. There are 20 yes/no questions related to the month prior to the use of the instrument. In the study by Mari and Williams29, 80% specificity and 83% sensitivity were obtained, with cutoff point of 7/8. In this study, it was chosen to use different cutoff points for men (5/6) and women (7/8), as suggested by Mari and Williams28, once a lower positive predictive value was found for men in comparison to women when the cutoff point 7/8 was employed for both genders (66 and 83%, respectively). The instrument can be used by an interviewer or it can be self-applied, but the same strategy should be adopted for all of the individuals.


The questionnaire of this study was previously applied in a group of six medical students, in order to estimate the necessary time for the answers, to assess comprehension in relation to the questions and to identify possible flaws in the instrument. The application of the questionnaires occurred in the classrooms after the previous schedule with the teachers in charge of the disciplines. After the objectives of the study were explained, the students were asked to sign the informed consent form, in case they agreed to it, and to insert their answers directly in the questionnaire.

Statistical analysis

Data were typed into an electronic worksheet and analyzed with the software STATA 10.029. At first, there was a descriptive analysis, when data consistency was checked and measures of central tendency were obtained, as well as variability and simple frequency tables, and corrections were made when necessary. The presence of CMD assessed by SRQ-20 was considered as the outcome of interest. The main explanatory variable was social support, assessed by SSS. The associations were analyzed by the χ2 test or the Fischer's exact test, when appropriate, and the 95% confidence interval was considered (95%CI). Crude and adjusted odds ratio were calculated by means of the backward stepwise method to control confusing variables. Variables with p < 0.25 obtained in the univariate analysis were included in the model, and those with p < 0.05 in the Wald test were considered to be significant in the multivariate analysis30.

Ethical considerations

The project was approved by the Research Ethics Committee of the medical school of Botucatu, after the approval of the council in the Graduate Medical Course. Students were informed about the objectives and procedures of the study, and their consent was requested only after the people who would apply the questionnaire explained about the research. After the informed consent form was filled out, it was detached from the rest of the questionnaire and kept separately, in order to make sure the identity of the participants and the obtained information would remain absolutely in secrecy. The possibility of getting in touch with the authors in charge of the project at any time was assured. All of the participants were told that no data would be individually publicized, and that only consolidated and grouped data would be object of scientific publication.


From a target-population of 545 enrolled medical students, 440 participated in the study, therefore, the response rate was of 80.7%. Since six participants did not answer the SRQ-20, it was not possible to classify them as to the presence of CMD and, therefore, they were excluded from the study. Therefore, the sample was comprised of 434 students. With the objective of controlling non-response, the sample of this study (n = 434) was compared to the target-population (n = 545) in relation to gender, and statistically significant differences were observed (p = 0.78). Mean age was 22 years old (standard deviation - SD = 2.3), ranging from 19 to 29 years old.

In Table 1 it is possible to observe the sample characteristics. Even though the participation rate was expressive, there was major loss among students in the last year of the course, especially among men. As in the population of college students, in this sample women were prevalent (58.1%). There were no differences between genders as to sociodemographic aspects. There were mostly single individuals, whose fathers' schooling was high, superior to 69%. One quarter of the students claimed not to have a religion. It was observed that most students earned 2 or 3 minimum wages for their monthly personal expenses, while about 4.0% reported monthly expenses of less than 2 minimum wages, in both genders.

The prevalence of CMD was of 44.9% (95%CI 40.0-49.2). Table 2 shows the prevalence according to sociodemographic characteristics. Higher prevalence of CMD was observed among women (46.8%) in comparison to men (42.3%), however, this difference was not significant (p = 0.35). The same occurred in relation to the year of the course, marital status, and monthly expenses in minimum wages. The fathers' schooling had a tendency to be associated with the prevalence of CMD (p = 0.08); however, this was not a linear tendency.

CMD: Common Mental Disorder

The arrangement of people in the household and the periodicity of visits to family members (Table 3) were not associated with CMD, even though the ones who visited families less than once a month were the only group with prevalence of CMD higher than 50% (p = 0.07). Adaptation to the city was inversely associated with the prevalence of CMD, so totally adapted subjects had lower prevalence (35.1%), while those who were partially adapted had prevalence of 61.0%, and those who were not adapted, 81.3%. Having a religion was proven to be a protective factor (p = 0.02), even though it was not repeated with the variable "importance of religion in your life" (p = 0.52). Conditions such as difficulty to make friends and feeling rejected were associated to the higher prevalence of CMD, respectively, 65.7 and 67.3%. Thinking of leaving the course was also associated with CMD, which showed the following gradation: subjects that never thought of leaving the course had the lowest prevalence (34.0%), followed by those who thought about it but no longer do (61.3%) and the ones who still consider the idea (81.5%).

CMD: Common Mental Disorder.

The final logistic regression model for CMD is presented in Table 5. The multivariate analysis included the following variables: year of the course, marital status, father's schooling, household arrangement, frequency of visits to the family, adaptation to the city, religion, difficulty making friends, feeling rejected, thinking of leaving the course and SSS domains. In the final model, there were only: "interaction" dimension of social support (p = 0.002), thinking of leaving the course (p < 0.001) and feeling rejected (p < 0.001). It was considered as important to maintain material support in the model, even though it presented a non-significant result considering p = 0.05 in order to control the analysis for this factor too.

In this study, the prevalence of CMD was of 44.9%, very similar to the one obtained in a previous study (44.6%), with students from the same college21, as proposed in the hypotheses of this research. However, the prevalence was higher than the one found for other medical students in investigations that also applied the SRQ-2015 , 16 ,18.20. It is possible that local characteristics, related to the structure of the course or even to regional variations, respond for these differences. In population studies conducted in Brazil, the prevalence of CMD is similar to that found here, and sometimes lower. In the study by Rocha et al.13, the prevalence of CMD among inhabitants of Feira de Santana, Bahia, was of 29.9%. However, it is important to mention that the sample in the study from Bahia included subjects with ages ranging from 15 to more than 70 years old, with very significant income variations, and these are considered to be risk factors for CMD. The students in this study were young, probably healthy and with higher income in relation to the general population, which leads to the assumption that they live in more favorable conditions and that the prevalence of mental distress should be inferior in comparison to the general population.

After the multivariate analysis, the following were independently associated with CMD: thinking of leaving the course, feeling rejected and the domain interaction support of SSS.

By comparing these data with the ones obtained by Lima et al.21, it is observed that the household arrangements did not show substantial changes: subjects living with friends were prevalent, followed by those who lived alone. However, studies conducted in the 1980s for the group of students in the same campus show there was an increase in the number of individuals living alone31. The socioeconomic conditions of these students are more favorable than the ones found for the general population, and their families also present with high schooling, and these aspects had already been identified in previous studies with medical students12 , 21.

One of the most frequent findings in literature concerning the presence of CMD is the association with the female gender and with worse life conditions, and these factors are not associated with CMD in this study. Probably, life conditions - identified here by the socioeconomic indicators - are very similar in the set of students included in this study. Therefore, by considering the homogeneity of the sample in relation to this parameter, small differences were not detected in the analyses. It is important to mention, however, that material support, measured by SSS, showed strong tendency to be associated with the high prevalence of CMD.

The comparison between the prevalence of CMD with regard to gender revealed no differences, which is in accordance with the results observed by other authors15 , 21. It is possible that, in groups of university students, differences between genders are not so explicit to be captured by screening instruments such as the SRQ-20, considering the approximation of the social roles of men and women in the routine of the university life.

The single association with the domain "interaction support", and not to the others, calls the attention. This domain intends to assess the "availability of people to have fun and relax with"27. According to Costa and Pereira32, inside the broad set of stressors faced by the students during the medical course, there are some inevitable ones, such as dealing with the pain and suffering of the patients. However, there is also a set of avoidable stressors, which concern the structure of the course and the relationship between peers and the school staff32. It is possible that students who do not dispose of "people to have fun and relax with" are more lonely and do not develop fighting strategies, such as the "search for social support" to combat the stressors they are facing with during the course. Zonta et al.33 conducted a qualitative study about the strategies to face stress developed by medical students in Universidade Federal de Santa Catarina, and they point to the value of interpersonal relationships with relatives, boyfriend or girlfriend and friends among the strategies used by the students to fight possible stressors.

Because of some characteristics of this study, its results should be seen with limitations. The first one concerns the cross-sectional nature of the study, which prevents suppositions about causality34, since the information about the outcome and explanatory variables are investigated simultaneously. It is also considered that the obtained data are limited in relation to its external validity. Even though the aspects of medical courses in Brazil are similar (full time course, which leads most of the students to depend on family members, among other characteristics), the results obtained in this study may not be generalized for all of the students. It is more likely that the courses conducted in medium-sized cities, which become the destination for most students who will attend the courses, would present similar results, since, for these young people who are far away from their families, social support from colleagues becomes more important. Finally, one last limitation refers to the fact that specific aspects of the medical course were not investigated, as well as possible abusive situations to which the students may have been submitted (haze, excessive demand for performance by authoritarian means etc.). A recent study conducted in the medical school of Ribeirão Preto showed that changes in the curricular structure were associated to lower levels of anxiety, when pedagogical strategies more focused on the students were implemented7. As to the matter of abuse, Wolf et al.35 had already noticed the association between such situations and depression and anxiety among medical students assessed in the four first years of the course. These aspects should be considered in further studies about mental health of the medical students and also in other fields of health.

One of the Strong points in this study consisted of the expressive participation of students. This result was probably owed to field planning, but it can also demonstrate the receptiveness of students to the investigations about their life conditions. The lower percentage of participation of students in the sixth year can be attributed to the fact that the internships in this phase are made in different locations, which may have prevented the participation of some students.

The association of social support with the higher prevalence of CMD found in this study suggests that strategies should be developed to stimulate and provide more interaction between students. As an example, mentoring programs, psychological support services and even the development of new pedagogical proposals that would stimulate and create interactive learning processes can help decrease the prevalence of mental distress. It is also possible that teaching strategies focused on the student, developed in small groups with the more active participation of students in their learning process, would favor more interaction between them, therefore making the environment healthier.
