###### Abstract
Independently, [PERSON] et al. presented a study applied to individuals with panic disorder and agoraphobia because of dependence on their cell phones [9]. Then, [PERSON] et al. examined the role of cell phones in the lives of Belorussian and Polish students. This study included the analysis of a sample of students from Belarus and Poland. Consequent to this study, they concluded that almost 20% of students in Poland and 10% in Belarus have symptoms of cell phone addiction [10]. Independently, [PERSON] et al. mentioned that smartphones may cause compulsive checking habits [1]. [PERSON] et al. argued that studies on the relationships between individuals and new technologies are relevant with the justification that new technologies produce changes in behavior, as well as feelings and symptoms, that must be studied and monitored continuously in modern society [11]. Then, [PERSON] and [PERSON], among their research results, mentioned that the most used application among young people is \"WhatsApp\" for instant messaging and that they may feel social exclusion if they are not included in a group [12]. [PERSON] et al. mentioned that, despite the many positive results, cell phones when used excessively are now often associated with potentially harmful and/or disruptive behaviors [13]. Independently, [PERSON] and [PERSON] considered nomophobia to be the phobia of the modern age that has been introduced into our lives as a by-product of the interaction between people and mobile information and communication technologies, particularly smartphones. In their studies, the authors have identified and described the dimensions of nomophobia and developed a questionnaire to measure this nomophobia [14]. The definition of nomophobia is controversial [5]. Therefore, it is necessary to define the one that will be used for this study. We consider nomophobia to be a behavioral addiction to cell phones, which is manifested by psychological and physical symptoms of dependence. [PERSON] and [PERSON] mentioned that nomophobia is an abbreviated form of \"no mobile phone phobia\" and is thought to stem from the excessive use of a mobile phone [14]. Independently, [PERSON] mentioned that nomophobia is a specific disorder caused by smartphone use [15]. Then, [PERSON] et al. mentioned that the purpose of their study is to find out the predominance of nomophobia among the smartphones used by undergraduates of West Bengal [16]. In their work, they used the Nompohobia Questionnaire (NMP-Q) developed by [PERSON] and [PERSON] [14]. The teaching of each course at the National University of Engineering requires on average 2 to 3 h; however, there are many factors that can cause distraction in the classroom. One factor is the excessive use of cell phones. [PERSON] et al. presented a study to analyze the relationship between the level of nomophobia and the distraction associated with the use of smartphones. The study population were nursing students from the University of Almeria in Spain [17]. [PERSON] et al. examined the impact of smartphone use in classroom learning; for this, they give a test to the students at the end of class, proving that those who had the lowest score were students that immediately answered the text messages from their cell phone with regard to who had kept their cell phone [18]. Independently, the studies of [19,20] mentioned that the ringing or notification of the cell phone, regardless of phone number, can be a distractor in the classroom. Then, [PERSON] et al. mentioned that the objective of the study is to evaluate the pattern of usage of mobile phones and its effects on the academic performance of dental students in India College. The authors concluded that there is an alarming indication of mobile phone addiction on the part of students, which affects their academic performance in a negative way [21]. [PERSON] et al. presented a study that aims to investigate the mediating effect of mindfulness on the relationship between attachment and nomophobia.
