description: The present data involves a large normative and representative sample of Greek adolescents (2012). Participants were selected in urban (Athens) and rural areas (Peloponnese, Korinthia prefecture) using the proportional stratified random sampling method, based on the latest inventory card of the Ministry of Education (Ministry of Education). The sample consisted of 2090 students attending 91 classes in 21 Greek public, academic and vocational track high schools of the extended Athens Area and Korinthia. One thousand thirty six participants (49.7% vs 51.55% in the population) were males and 1050 (50.3% vs 49.45% in the population) were females (mean age ¼ 16.16, SD ¼ 0.911). The ratios of high schools and students were identified: 1) between the extended Athens area and Korinthia; 2) between academic vs vocational track high schools within these areas. Based on these quotas school units and participants were randomly selected. The significantly higher proportions of adolescents, who are residents of urban areas and enrolled in academic track high schools, reflect the nation’s high urbanization and strong academic tendencies (National Statistical Authority of Greece, 2012) respectively. Additionally, chi square tests were conducted to confirm that the distribution of the valid sample did not differ significantly from that of the original population in terms of area of residence and type of school. The estimated maximum sampling error with a sample size of 2090 is 2.14% at the 95% confidence level (Z ¼ 1.96). Response and parental consent rates were obtained for over 95% of the sample Parental consent refers to the ratio of students whose guardians approved their participation to the initial number selected (98%). As the research was approved by the ministry of education, the method of negative consent was applied, which means that only parents who did not consent had to inform the school principal. Response rate was calculated by the ratio between students who participated and the selected number of students who received parent consent (95%). A research activity during school time was perceived as highly desired compared to regular teaching. However, there were cases of students whose guardians may have consented but they were absent from class (illness) during the scheduled data collection day (5%). Instruments used in the data include the (i) Internet Addiction Test (IAT; Young 1998a ); (ii) Presence II questionnaire (Witmer and Singer 1998); (iii) Online Flow Questionnaire (Chen, Wigand, and Nilan 1999); (iv) Symptom Check List 90 (Derogatis and Savitz 1999 ); (v) Rosenberg Self-Esteem Scale (Rosenberg 1965); (vi) Five-Factor Questionnaire for Children (Fünf-Faktoren-Fragebogen für Kinder) (Asendorpf and Van Aken 2003); (vii) Generalized Self-Efficacy Scale (Schwarzer 1993); (viii) Family Adherence and Cohesion Evaluation Scale (Olson 2000); (ix) Sociometric Questionnaire (Coie, Dodge, and Coppotelli, 1982); (x) Greek version of the Experience of Close Relationships Revised (Tsagarakis, Kafetsios, and Stalikas 2007); (xi) demographic and Internet use questions; and (xii) school grades of the participants retrieved from their school records.
