The fear of negative evaluation is defined as the fear or distress that a person feels when there is a possibility or indication that they might be negatively evaluated. It is also one of the aspects of social anxiety. There are many characteristics of an individual that can determine the level of fear in the situations of social evaluation. The aim of this research is to examine if there is a connection between the fear of negative evaluation in adolescents and some of their characteristics, as well as to determine whether adolescents differ between each other according to the educational style of their parents. The study was conducted on a sample of 385 subjects – 284 females and 101 males from the age of 14 to the age of 19. The results of this research show that there is a significant difference in the fear of negative evaluation in regard to gender. Adolescent girls are more scared than adolescent boys, but there is no significant difference in regard to the stage of adolescence. Moreover, the results show that there is a moderate positive correlation between loneliness and the fear of negative evaluation. Also, there is a moderate negative correlation between self-esteem and the fear of negative evaluation, as well as a low positive correlation between Internet addiction and the fear of negative evaluation. This means that with the increase of loneliness, lower self-esteem and the increase of Internet addiction the fear of negative evaluation also increases. Furthermore, the results of this research show that there is a significant difference in the fear of negative evaluation depending on the parenting style of adolescent mothers regardless of the parenting style of adolescent fathers. In the adolescents that perceive their mothers as authoritarian, the fear of negative evaluation is more expressed than in those that perceive their mothers as authoritative or permissive. At last, it has been shown that gender, loneliness, self-esteem and Internet addiction are considered as important independent predictors of the fear of negative evaluation: female gender, loneliness and Internet addiction are all positive predictors, whereas self-esteem is a negative predictor of the fear of negative evaluation.
