ABSTRACT

Aim: Impact of smartphone (SP) addiction on knowledge, cognitive, and psychomotor skills of dental students at Jazan University.

Materials and methods: A cross-sectional study was conducted among 100 students (male and female) in the dentistry college, Jazan University. A validated questionnaire was used to collect the data of SP usage to check its addiction among the studied subjects. Participation in the study was voluntary. Once the responses from the participating students were obtained; they were classified as SP-addicted and SP non-addicted students. Later, their performance in the theory exam (for knowledge and cognitive skills) and clinical exam (for psychomotor skills) along with their addiction status and gender were correlated and compared by doing statistical analysis using the Chi-square test.

Results: The results showed no significant negative impact of SP addiction on knowledge, cognitive, and psychomotor skills of dental students at Jazan University.

Conclusion: This is the first study known to the authors that deals with the effects of SP addiction on the knowledge, cognitive, and psychomotor skills of dental students. The limitations of this study warrant further studies in this regard with a larger sample size and better design to further study the effects of SP use and addiction and make evidence-based recommendations on the use of SP and its effects on operative dentistry skills among dentists.

Clinical significance: Understanding the effects of SP addiction on knowledge, cognitive, and psychomotor skills will help in modifying the behavior related to the use of SPs by dental students and improve their academic performance.

Keywords: Dental students, Psychomotor skills, Smartphone addiction..

INTRODUCTION

The internet with the introduction of smart mobile gadgets has become an integral part of human–human communication. Smartphones (SPs) are powerful and useful tools as they offer combined services of the mobile phone and the internet. They have different purposes which include entertainment, electronic commerce, cultural exchange, rapid information transfer, and dissemination. In medicine and dentistry, it is used for the dissemination of public health information, telemedicine, and virtual learning for dental and medical students.18 Moreover, SPs offer the benefits of social media-multifunctional networking tools usage at the convenience of our palms; content production (blogs [Blogger, Tumblr], information aggregation (Wikipedia), media sharing (YouTube, Tik Tok, Flickr, Instagram Wikimedia commons), microblogs/Tumblelogs [Twitter, Sina weibo]), social networking (Twitter, Facebook, MySpace, Google Plus), professional networking (LinkedIn), virtual reality, and gaming environments (Second Life) are all widely used.9,10 The constant use of these social networking spaces have changed the way we socially interact. It has become the prime medium of expression and communication rendering life without their use unthinkable.5

Studies have shown that overuse of SPs can cause behavioral problems including impulse control disorders, lessen social interaction, attenuate physical activity, can cause relationship problems, harm academic and professional performance, and could lead to physical ailments like blurred vision, problems in the eardrum, and musculoskeletal pain in wrists and back of the neck. They could also cause fatigue and sleep disorders. Thus, excessive SPs use can hamper both physical and mental health.5,1115 Smartphone addiction is considered as the inability to limit the usage of SPs despite adverse effects on users. Several questionnaire-based scales are in use to measure the self-described addiction, problematic behavior due to SP use, nomophobia, and internet addiction.11,1618 Smartphone addiction proneness scale (SAPS) questionnaire by Kim et al. has been used in this study which was developed based on the previous existing questionnaires on the internet and phone addiction, it is validated and appears to be reliable for screening adolescents for SP addiction.19

There is a building view in the medical community that the use of a two-dimensional flat screen and excessive internet usage results in loss of creativity and manual dexterity, which could hamper clinical skills among students.2022 However, others have a view that various uses of the internet could improve manual dexterity; gaming could improve concentration and dexterity while texting could help reflexes get faster.23 Hence, this study was designed to study SP usage, its addiction among final year dental students at Jazan University, and its possible effects on knowledge, cognitive, and psychomotor skills (manual dexterity) in clinical operative dentistry.

MATERIALS AND METHODS

This is a cross-sectional study done among the fifth-year dental students aged between 20 years and 25 years who were attending clinical operative dentistry course. This study was designed to check the effect of SPs use and addiction on their academic performance and manual clinical dexterity of the students. Participation in this study was voluntary and a random sampling method was adopted. This study was conducted over a period of 2 months, from March to April 2019. The 100 subjects who accepted participation by signing the informed consent were included in this study. The electronic questionnaires were distributed to the students who appeared for both the theory and clinical final exams. Those who missed either of the exams (theory/clinical) were excluded from the study. All the students who attended the exams (53 males and 47 females) participated in the study. All the participants completed the questionnaire within a day. Any ambiguity was clarified and the completeness of the forms was checked.

The ethical committee of the Institutional Review Board of the College of Dentistry, Jazan University, Kingdom of Saudi Arabia, approved the study.

Questionnaire Details

A validated SAPS was used to measure the prevalence of SP addiction19 (Table 1).

This scale consists of 15 self-rating questions, which were subdivided into three subdomains, including disturbance of adaptive functions, virtual life orientation, withdrawal and tolerance.

These questions were rated on a 4-point Likert-type scale from 1 (strongly disagree) to 4 (strongly agree).

Between the score range of 15 and 60, 42 was selected as a clinical cutoff score to consider a student was addicted and some questions to avoid response bias were scored in reverse order as recommended by the article.19

Knowledge, Cognitive, and Psychomotor Skills Evaluation

The theory exam in operative dentistry included a series of examinations with question papers consisting of short answers, short essays, and multiple-choice questions to evaluate the knowledge and cognitive skills of the students whereas the psychomotor skills were assessed by conducting a clinical exam which included assessment of preoperative procedures, cavity preparation, restorative procedures, and time management. Two qualified clinical examiners assessed the subjects and agreed upon marks were assigned to the students based upon predetermined rubrics approved by the department.

The exam results were converted to grades from I to VI, the distribution of grades percentage was as follows, I (90–100%), II (80–89%), III (70–79%), IV (60–69%), and VI (59% and less).

Statistical Analysis

Data collected were entered in MS Excel and tabulated accordingly by one of the independent investigators. The statistical analysis was done using SPSS ver 23. (IBM, USA) by an independent biostatistician, a significance value (α) p < 0.05 was considered to be statistically significant, and the confidence interval was set at 95% with a power of the test (β) of 80%. Frequencies and percentages were used for categorical variables in descriptive analysis. Continuous variables were presented as mean with standard deviation. Pearson’s Chi-square test was used for testing any statistically significant association of categorical variables.

RESULTS

In this cross-sectional study 100 students participated, among them, 53 were male students and 47 were female students. This study showed that 3.8% (N = 2) male students and 4.3% (N = 2) female students studied were addicted to SP usage. Although female students were relatively more addicted to SP usage; however, it was not statistically significant (Table 2).

The exams for students were conducted as a theory exam (exam A) and clinical exam (exam B) in operative dentistry. Among addicted students in exam A, 25% (N = 1) got grade III and 75% (N = 3) students got D (Table 3). In exam B, all the addicted students [N = 4 (100%)] got grade III (Table 4). However, these results showed no statistical significance when the addicted and non-addicted subjects were compared. The cumulative grades (exam A + exam B) among addicted students showed that 25% (n = 1) got grade III while 75% (n = 3) students got grade IV. The cumulative results showed that 75% of addicted students got the lowest grades (Table 5). Nevertheless, the results were not statistically significant.

In exam A, the male students’ (mean = 68.7%) performance was relatively better than female students (mean = 67.825) whereas, in exam B, the male students’ (mean was 79.96%) performance was relatively poorer than the female students (81.43). In the case of a combined exam (A + B) results, female students (73.64%) performed relatively better than male students (73.52%). However, these results were not statistically significant (Table 6).

DISCUSSION

Smartphone use has become an integral part of the day-to-day life activities of students, including communication in professional life, family and friends, shopping, and its use for academic purposes like attending lectures, webinars, meetings especially in pandemic situations like COVID-19. Furthermore, nowadays, because of a shift from conventional hard copy books to ebooks, there is a tendency in students to read through ebooks because of convenience, it seems like the use of SP will be increasing in the coming days. Hence, it is very important to know the kind of impact SP usage has on the academic performance of students, including knowledge, cognitive, and psychomotor skills so that necessary guidelines and recommendations can be made accordingly.

Many studies have assessed the effect of SP usage on various aspects of the academic performance of university students.5,12 Scientific literature has emphasized, argued, and addressed the importance of studying the effect of SP on educators and dental students.5,6 Still, there were no studies found which have studied the impact of SP use on psychomotor skills of the students, specifically operative dentistry related psychomotor skills, which are one of the most basic skills required to be acquired by dental students to become competent dentists. This is the first study to the best of our knowledge to study the impact of SP usage and addiction on the manual dexterity of dentists in the field of operative dentistry.

Final year BDS students were chosen in the study because they have already obtained enough clinical training in operative dentistry and their clinical operative exam will be the last exam in the division of operative dentistry; it is expected that the students should be competent enough to perform all operative dentistry procedures for undergraduate students.

A validated SAPS was used to measure the prevalence of SP addiction19 (Table 1). This scale was used because it included questions on various aspects of the effects of SP use, including virtual life orientation, adaptive functions, withdrawal and tolerance. Also, the questions were rated on a 4-point Likert-type scale from 1 (strongly disagree) to 4 (strongly agree). To avoid response bias, some items were scored in reverse order. The clinical cutoff score was kept as 42.

For convenience, the questionnaire was prepared on google form, shared and the data were collected. The data were then transferred to MS Excel and the statistical analysis was carried over. The students were categorized into those who were addicted and those who were non-addicted to the SP use. The exam results of both the theory and clinical were used both individually and as cumulative ones and were compared with the addiction results of the subjects studied.

In the current study, it was found that 4.05% of students were considered addicted to SP use. Among the addicted students in the theory exam (exam A), 25% of students got grade III and 75% of students got grade IV. However, the results were not statistically significant. The results were in contrast to the studies published by Samaha and Hawi,12 Halboub et al.,5 and Prasad et al.24 showed the academic performance of the SP addicted students to have been adversely affected. This difference may be due to the difference in the psychometric scales employed and the size of the sample used.

It was also found from the study that male students’ performance was relatively better in the theory exam than female students, whereas in the clinical exam, female students’ performance was better than male students. Although in combined results female students performed better than male students which are reflected in an earlier study also.5 However, the results were not significant.

CONCLUSION

Within the limitations of this study, no statistically significant adverse effect was found on the use of SP on the academic and clinical operative skills of the dental students. However, this warrants further studies in this regard with larger sample sizes and better design to further study the effects of SP use and addiction and make evidence-based recommendations on the use of SP and its effects on operative dentistry skills among dentists.
