Study Design
We conducted an online survey of Sudanese medical students using convenience sampling. The survey was available on various social media platforms from January 2nd to February 25th, 2024 and could be accessed by anyone with the link. We shared information about the study with a group of collaborators to help collect data. We did not contact respondents prior to starting the study. We invited individuals to participate in a study that examined the impact of smartphone addiction on mental health and sleep quality among medical students in Sudan. This included a Participant Information Sheet (PIS) and the survey link. The PIS provided details about the study's goals, protection of personal data, survey length, and the right to withdraw from the study at any time. We emphasized that participation in the survey was voluntary and there were no financial incentives. The target population was Sudanese medical students, regardless of their location.
Data Collection
We developed an online questionnaire based on recent literature and input from faculty members at the University of Alzaiem Alazhari. The questionnaire covered various topics, such as sociodemographic data, Suboptimal Health Status questionnaire, sleep condition indicator, Smartphone addiction scale, and depression, anxiety, and stress scale. The questions were randomized to reduce response bias, and respondents were required to complete all mandatory items. They had the option to review and change their answers using a 'back' button. To ensure clarity and relevance, we piloted the survey with 30 medical students. We received feedback that helped improve the wording of the questions, although most respondents found the questions clear, relevant, and specific. We used Google Forms for data collection, which was distributed by 26 collaborators through personal and professional groups, as well as social media platforms like Facebook, WhatsApp, Twitter, and LinkedIn. We also posted study information on Sudanese social media groups for medical students and sent reminders on days 3 and 7 of the data collection period. We did not collect respondents' IP addresses to maintain anonymity and confidentiality, although Google Forms only allowed one submission per IP address.
Data Management and Statistical Analysis:
Responses were securely stored in Google Sheets, accessible only to the study team. The data was thoroughly cleaned and analyzed using IBM's Statistical Package for Social Sciences (SPSS) software, specifically version 26 (https://www.ibm.com/docs/en/spss-statistics/26.0.0).Continuous data was presented as mean ± SD, while categorical data was presented as numbers (percentage). To assess the normality of the data, we used the Kolmogorov-Smirnov test. For normally distributed data, we used an independent t-test to determine significant differences between groups. In cases where the null hypothesis of the Kolmogorov-Smirnov test was rejected, we used the Mann-Whitney U test. To determine significant differences between groups for categorical data, we used either the Chi-square test or Fisher's exact test. A p-value of less than 0.05 was considered significant.
Ethical Approval:
The study received approval from the Research and Ethics Committee at the University of Alzaiem Alazhari, Sudan. The study adhered to the ethical standards outlined in the 1964 Helsinki Declaration and its subsequent amendments, as well as other approved ethical guidelines. Informed consent was obtained from all participants, as indicated in the data collection tool. To ensure comprehensive and accurate reporting of the study findings, we followed the Checklist for Reporting Results of Internet E-Surveys (CHERRIES)20. We confirm that all methods were conducted in accordance with relevant research ethics guidelines and regulations. Participants provided informed consent at the start of the online survey before completing the questionnaire.
A total of 1704 questionnaires were collected. Of all the participants, 1176 (69.0%) were female and 528 (31.0%) were male. The mean age of the participants was 491. Age was classified into categories as follows: less than 18 years, 40 (2.3%); 19-21 years, 368 (21.6%); and more than 21 years, 1296 (76.1%). Among these, approximately 56 (3.3%) were in the first level of university, followed distantly by 152 (8.9%) in the second level, 432 (25.4%) in the third level, 528 (31.0%) in the fourth level, 360 (21.1%) in the fifth level, 128 (7.4%) in the sixth level, and 48 (2.8%) had graduated from the university.
The study revealed that 136 (8.0%) were single, while the majority, 1568 (92%), were married. Moreover, only 792 (46.55%) of the participants lived inside Sudan, while 912 (53.5%) lived outside Sudan. Additionally, more than half of the respondents, 1048 (61.5%), had a low SHSQ prevalence, while 656 (38.5%) had a high prevalence. 336 (31.5%) of the participants had a low rate of SCI prevalence, while 1168 (68.5%) had a high rate according to the SSI prevalence rate.
About 552 (32.4%) had a low SAS prevalence, while 792 (46.5%) had a moderate level, and 360 (21.1%) had a high level. According to the analysis, the mean of depression was 1.5, while the standard deviation was 0.662. Approximately 1016 (59.6%) had mild depression, 528 (31.0%) had a moderate level, and 160 (9.4%) had severe depression. The mean of anxiety was 1.56, with a standard deviation of 0.622. Of all the students, 864 (50.7%) had a mild anxiety level, 720 (42.3%) had a moderate level, and 120 (7.0%) had a severe anxiety level. The mean value of stress was 1.37, with a standard deviation of 0.634. 1216 (71.4%) of all the students suffered from mild stress, 344 (20.2%) had a moderate stress level, and 144 (8.5%) had a severe level of stress.
