The relationship of smartphone addiction with chronotype and personality structures in university students

ABSTRACT The present study aims to reveal whether gender, age, personality traits, chronotypes, and smartphone screen-time predict smartphone addiction. This study used the composite scale of morningness, big five inventory, and smartphone addiction scale for collecting data. Females showed higher levels of smartphone addiction than males. Furthermore, age was not a significant predictor of smartphone addiction. We revealed that conscientiousness and neuroticism were significant predictors of smartphone addiction while extraversion, agreeableness, and openness to experience were not. We also found that neurotic people had higher levels of smartphone addiction. We revealed in this study that people with evening chronotypes had higher levels of smartphone addiction. In conclusion, female, neurotic, eveningness chronotypes, and students who use smartphones at high levels were more addicted to smartphones.
