Investigating the relationship between personality, chronotype, computer game addiction, and sleep quality of high school students: A structural equation modelling approach.

This study examines the relationship between high school students' age, gender, personality, computer game addiction, chronotype, and sleep quality using structural equation modelling. For this purpose, the study was planned according to the correlational research design, one of the most common quantitative research methods. The sample of the study consisted of 922 students who accepted to participate and completed the scales. Of the 922 high school students in the sample, 528 were girls, and 394 were boys. In the study, the Computer Game Addiction Scale for Adolescents, Sleep Quality Scale, Composite Scale of Morningness (CSM), and Big Five Inventory were used to measure the variables. Among the variables involved, personality traits, such as consciousness, neuroticism, and openness to experience, were significantly related with morningness-eveningness. Besides, gender and being evening or morning types were found to be significantly related with game addiction. However, sleep quality was predicted by computer game addiction and morningness-eveningness. It was found that the fit indices of the model have an acceptable and good fit in explaining the variables.
