A novel model to predict mental distress among medical graduate students in China

ABSTRACT:

Background

Poor mental health was reported among medical graduate students in some studies. Identification of risk factors for predicting the mental health is capable of reducing psychological distress among medical graduate students. Therefore, the aim of the study was to identify potential risk factors relating to mental health and further create a novel prediction model to calculate the risk of mental distress among medical graduate students.

Methods

This study collected and analyzed 1079 medical graduate students via an online questionnaire. Included participants were randomly classified into a training group and a validation group. A model was developed in the training group and validation of the model was performed in the validation group. The predictive performance of the model was assessed using the discrimination and calibration.

Results

One thousand and fifteen participants were enrolled and then randomly divided into the training group (n = 508) and the validation group (n = 507). The prevalence of severe mental distress was 14.96% in the training group, and 16.77% in the validation group. The model was developed using the six variables, including the year of study, type of student, daily research time, monthly income, scientific learning style, and feeling of time stress. The area under the receiver operating characteristic curve (AUROC) and calibration slope for the model were 0.70 and 0.90 (95% CI: 0.65 ~ 1.15) in the training group, respectively, and 0.66 and 0.80 (95% CI, 0.51 ~ 1.09) in the validation group, respectively.

Conclusions

The study identified six risk factors for predicting anxiety and depression and successfully created a prediction model. The model may be a useful tool that can identify the mental status among medical graduate students.

Project description:BACKGROUND:Psychological distress in medical students is a global issue and poses a risk to their health, academic performance, and ability to care for patients as clinicians. There has been limited research on psychological distress levels in students prior to starting medicine and no direct comparison between undergraduate and graduate-entry students. METHODS:Psychological distress was assessed using the 21-item Depression Anxiety and Stress Scale in 168 undergraduate-entry and 84 graduate-entry medical students at two separated campuses of the same university in the orientation week prior to starting classes. Mean scores and severity proportions were compared between the two cohorts of students. Demographic data was also collected and compared to distress scores using subgroup analysis. RESULTS:The response rate for the study was 60.9%. The majority of undergraduate and graduate-entry medical students were within the normal limits for depression (67.2% versus 70.2%, p = 0.63), anxiety (56.5% versus 44.0%, p = 0.06), and stress scores (74.4% versus 64.2%, p = 0.10). There was no significant difference between severity groups except for severe stress (2.3% versus 9.5%, p = 0.01). The mean scores of the clinically distressed groups indicated moderate levels of depression, moderate anxiety, and moderate stress scores. There were no significant differences between undergraduate or graduate-entry students for depressive ([Formula: see text] = 17.02 versus 15.76, p = 0.43), anxiety ([Formula: see text] = 14.22 versus 13.28, p = 0.39), and stress scores ([Formula: see text] = 20.83 versus 22.46, p = 0.24). Female gender and self-believed financial concerns were found be associated with higher levels stress in graduate entry students. CONCLUSIONS:The majority of medical students enter medical school with normal levels of psychological distress. However, a large number of undergraduate and graduate-entry medical students have significant levels of depressive, anxiety, and stress levels, without a significant difference between undergraduate or graduate-entry students. There are several limitation of this study but the results suggest that education and intervention may be required to support students from the earliest weeks of medical school.

Project description:Defining professionalism in this constantly evolving world is not easy. How do you measure degrees of benevolence and compassion? If it is so obvious to our profession, what professionalism is, then why is it so difficult to teach it to medical students and residents? Today's definition of medical professionalism is evolving - from autonomy to accountability, from expert opinion to evidence-based medicine, and from self-interest to teamwork and shared responsibility. However, medical professionalism is defined as the basis for the trust in the patient-physician relationship, caring and compassion, insight, openness, respect for patient dignity, confidentiality, autonomy, presence, altruism, and those qualities that lead to trust-competence, integrity, honesty, morality, and ethical conduct. The purpose of this study is to explore professionalism in terms of its fundamental elements among medical students of Universiti Sultan Zainal Abidin (UniSZA). This was a cross-sectional study carried out on medical students of UniSZA. The study population included preclinical and clinical medical students of UniSZA from Year I to Year V of academic session 2014/2015. The simple random sampling technique was used to select the sample. Data were collected using a validated instrument. The data were then compiled and analyzed using SPSS Version 21. Out of 165 questionnaires distributed randomly among Year I to Year V medical students of UniSZA, 144 returned, giving a response rate of 87%. Among the study participants, 38% (54) and 62% (90) were males and females, respectively. The grand total score was 170.92±19.08. A total of 166.98±20.15 and 173.49±18.09 were the total professionalism score of male and female study participants, respectively, with no statistically significant (P=0.61) differences. This study found almost similar levels of familiarity with all fundamental issues of professionalism with no statistically (P>0.05) significant differences. Medical faculty members should give more effort for the professional development of medical doctor. Henceforth, researchers believe and expect that the country will produce more rational and holistic medical doctors.

Project description:BACKGROUND:Mental distress is a major public health problem which includes anxiety, depression and somatic symptoms such as sleeping problems, fatigue and headache. University students are consistently reported to have higher levels of mental distress compared to the general population. Although university students with mental distress have significantly impaired cognitive functioning, learning disabilities and poor academic performance, the burden of this problem in Tanzania is unknown. This study aimed to determine prevalence and factors associated with mental distress among undergraduate students in northern Tanzania. METHODS:A cross-sectional study was conducted among undergraduate students at Kilimanjaro Christian Medical University College from April-July 2018. Simple random sampling technique using probability proportional to size was used to sample students from their respective classes. Mental distress was screened using the self-reporting questionnaire (SRQ-20). Data was analyzed using Stata version 15.1. Frequencies and percentages were used to summarize categorical variables while mean and standard deviation for numeric variables. Multivariable logistic regression was used to determine factors associated with mental distress adjusted for potential confounders. RESULTS:A total of 402 undergraduate students participated in this study, 14% screened positive for mental distress. Residing off-campus (OR?=?0.44, 95%CI 0.20-0.96) and perceived availability of social support (OR?=?0.22, 95%CI 0.11-0.45) reduced the odds of mental distress while students with family history of mental distress (OR?=?2.60, 95%CI 1.04-6.57) and those with decreased grades than anticipated (OR?=?3.61, 95%CI 1.91-6.83) had higher likelihood of mental distress. CONCLUSION:One in every ten students screened was positive for mental distress. Those who reported a family history of mental illness and lower grades than anticipated had higher response of mental distress. To relieve students from stress and frustrations related to studies and their lives in general, this study recommends awareness creation, counselling to help those with mental health issues, establishment of student drop-in centers for such services and promotion of social and recreational activities at the college.

Project description:BackgroundIn 2012, over half of US medical students experienced burnout and depression. Since that time, there have been many changes to student demographics, school resources and awareness of burnout in the medical field altogether. New tools are also available to screen for student distress, a condition that correlates with low mental quality-of-life, suicidal ideation and serious thoughts of dropping out. Despite increased attention on wellbeing and improved screening methods, no large-scale studies have evaluated student distress in the modern era of medical education. The objective of this study was to determine the current prevalence of medical student distress and contributing risk factors.MethodsStudent wellbeing from a national cohort of US medical students was measured with an electronic survey in a prospective, observational survey study from 2019-2020. Medical student distress was defined as a Medical Student Wellbeing Index (MS-WBI) of ≥4. Demographic details including age, race, gender, marital status, disability, desired specialty, and debt burden were evaluated in a multivariate logistic regression model to determine possible risk factors for the development of distress.ResultsA total of 3,162 students responded to the survey, representing 110 unique medical schools. Of these respondents, 52.9% met criteria for distress and 22% had either taken or considered taking a leave of absence for personal wellbeing. Independent risk factors for distress included involvement in the clinical phase of medical school (OR 1.37); non-male gender (OR 1.6); debt burden >$20,000 (OR 1.37), >$100,000 (OR 1.81), and >$300,000 (OR 1.96); and disability status (OR 1.84).ConclusionsMedical student wellbeing remains poor in the modern era of medical education despite increased attention to wellbeing and increased availability of wellbeing resources. Disability status is a novel risk factor for distress identified in this study. The persistence of previously identified risk factors such as non-male gender, debt burden and clinical phase of school suggest that efforts to curb medical student distress have been inadequate to date.

Project description:BackgroundThere is limited evidence on the extent of the perceived need and barriers to professional mental health service delivery to university students with mental distress in low- and middle-income countries (LMICs). This study was designed to assess the prevalence of mental distress, perceived need for professional mental health care and barriers to the delivery of services to affected undergraduate university students in Ethiopia.MethodsA multi-stage sampling technique was used to recruit 1135 undergraduate university students. Symptoms of mental distress were evaluated using the Self-Reported Questionnaire (SRQ-20) and a score of above seven was used to identify positive cases. The perceived need for professional mental health care was assessed using a single 'yes or no' response item and barriers to mental health care were assessed using Barriers to Access to Care Evaluation (BACE-30) tool. Percentage, frequency, mean, and standard deviation were employed to summarize demographic characteristics of the participants and to identify common barriers to mental health care service. Moreover, the association of demographic variables with total mean scores of BACE-III sub-scales was modeled using multiple linear regression.ResultsThe prevalence of mental distress symptoms was 34.6% and the perceived need for professional mental health care was 70.5% of those with mental distress. The top five barriers to receiving professional mental health service were (a) thinking the problem would get better with no intervention, (b) being unsure where to go to get professional help, (c) wanting to solve the problem without intervention, (d) denying a mental health problem existed, and (e) preferring to get alternative forms of mental care. Coming from a rural background, being a second and fourth-year student, and a family history of mental illness were significantly associated with barriers to receive professional mental health service.ConclusionThe high prevalence of mental distress, the paucity of mental health care, and the report of barriers to access what professional mental health care there is among Ethiopian undergraduate students is a call to address the disparity.
