Background:
Today, mobile phones are recognised as an inseparable part of our daily lives, facilitating communication between users. Based on the studies, addiction to cell phones can lead to several complications including depression, anxiety, anger, and aggression.
Aim:
This study aimed to investigate nomophobia (no mobile phone phobia) among medical students of Islamic Azad University, Tehran Branch.
Methods:
This descriptive cross-sectional study was conducted on 100 students studying in different majors of medical sciences in Islamic Azad University, Tehran Branch, from 2016 to 2017. Demographic data of all participants were recorded in a data sheet. In the next stage, a questionnaire was designed by the researcher to evaluate the effect of age, gender, education, and the duration of using cell phone variables on discomfort, anxiety, and insecurity due to lack of access to cell phone or other related issues. Raw data were analysed using SPSS statistical software version 21. The significance level was considered P < 0.05.
Results:
The results of the study showed that participants with lower mean age felt more discomfort, anger, anxiety, and insecurity due to lack of access to mobile phones and other related issues compared to other people. However, no variable was statistically significant (P-value > 0.05). Except anxiety, results showed that longer duration of mobile phone use might lead to a significant decrease in discomfort, anger, and insensibility variables among users (P-value > 0.05). The incidence of nomophobia (with its different aspects) was significantly lower in females (P-value > 0.05). Also, in participants with higher educational status, the nomophobia was recorded to be more frequent (P-Value > 0.05).
Conclusion:
Understanding the pattern of nomophobia occurrence among cell phone users can facilitate our path to prevent its harms including discomfort, anger, anxiety, and feeling of insecurity among users of technology.
