The purpose of this work is to define the clinical and social predictors of headaches in children and adolescents. Material and Methods. We performed clinical examination of children and adolescents, which included studying their symptoms, anamnesis, somatic and neurological objective signs, survey using our original questionnaire and survey in the framework of an international project to study headaches «World Children and Adolescent Headache Project». The type of headache was diagnosed using international diagnostic criteria of the International Classification of Headache Disorders, 3rd edition (beta release). As a result of our study, we obtained the data about the most significant lifestyle factors (among those studied) influencing the number of days with headache per month, calculated linear coefficients and a predicting mathematical model for children. The sensitivity of the model for the prognosis of chronic tension type headache is 63%, specificity — 81 %. Conclusion. In this paper we describe criteria for the prognosis of primary headaches in patients aged from 8 to 18 years old.

The objective of the present study was to examine the effects of aggression and conflict-managing skills on popularity and attitude to school in Russian adolescents. Three types of aggression (physical, verbal, and indirect), constructive conflict resolution, thirdparty intervention, withdrawal, and victimization were examined using the Peer-Estimated Conflict Behavior (PECOBE) inventory [Bjorkquist and Osterman, 1998]. Also, all respondents rated peer and self-popularity with same-sex classmates and personal attitude to school. The sample consisted of 212 Russian adolescents (101 boys, 111 girls) aged between 11 and 15 years. The findings attest to significant sex differences in aggression and conflict resolution patterns. Boys scored higher on physical and verbal aggression, and girls on indirect aggression. Girls were socially more skillful than boys in the use of peaceful means of conflict resolution (they scored higher on constructive conflict resolution and third-party intervention). The attributional discrepancy index (ADI) scores were negative for all three types of aggression in both sexes. Verbal aggression is apparently more condemned in boys than in girls. ADI scores were positive for constructive conflict resolution and third-party intervention in both genders, being higher in boys. In girls, verbal aggression was positively correlated with popularity. In both sexes, popularity showed a positive correlation with constructive conflict resolution and third-party intervention, and a negative correlation with withdrawal and victimization. Boys who liked school were popular with same-sex peers and scored higher on constructive conflict resolution. Girls who liked school were less aggressive according to peer rating. They also rated higher on conflict resolution and third-party intervention. Physical aggression was related to age. The results are discussed in a cross-cultural perspective.
