Abstract
Background and Objectives: Due to the quick development and widespread use of mobile phones and its various effects on the interaction and communication, it is important to study its negative effects on the health of cellphone users. The overall aim of the present study was to investigate cellphone overuse as a predictor of sleep quality as well as anxiety and depression among college students.
Materials and Methods: This descriptive–correlation study was carried out on all the students of Kharazmi and Payam-e-Noor universities of Karaj during 2014-2015 school years and the sample consisted of 240 persons who were selected by multistage cluster sampling. For data gathering, questionnaires such as cellphone over use scale (COS), Pittsburgh sleep quality index (PSQI) and hospital anxiety and depression scale (HADS) were used. Data analysis was performed using Pearson’s correlation and multiple regressions (stepwise) methods with SPSS 21 software and 0.01 P value.
Results: The results of regression showed that the variable of cellphone over use and the variance of sleep quality, anxiety and depression were respectively 0.31% and 0.14%, which predicted and were positively and significantly (r = 0.56, P< 0.01; r= 0.38, P < 0.01) correlated with sleep quality, anxiety and depression.
Conclusions: The variable of cellphone overuse can predict and cause changes in sleep quality, anxiety and depression among students and psychotherapists can control these factors to enhance the quality of life and mental health of them.
