摘要：AbstractRecent studies indicate that psychological features are related to various kinds of internet use. This research is aimed to appraise the role of family structure, personality characteristics and demographical factors in predicting problematic use of internet. Through stratified random sampling, 279 Shahid Beheshti University students were selected as the subjects of the research. The aforementioned features were assessed by the following instruments: Family Adaptability Cohesion Evaluation Scale (FACES-III), Five Factors Personality Questionnaire (NEO-FFI) and Generalized Problematic Internet Use Scale (GPIUS).The problematic use of internet comprised such subscales as Mood Alteration, Social Benefit, Compulsivity, Excessive Time, Withdrawal, and Interpersonal Control. The results of Pearson Correlation Coefficient and Multiple Regression showed that Family Cohesion predicts subscales of Mood Alteration, Social Benefits, Compulsivity, Excessive Time, and Withdrawal. Whereas Neo's Neuroticism predicated all of subscales of GPIUS, Agreeableness predicated subscales of Mood Alteration and Compulsivity; Openness predicates Compulsivity. Where being female predicates Interpersonal Control, being male predicates Mood Alteration, Social Benefit, Compulsivity, Excessive Time, and Withdrawal.
