At the present time, adolescents are in particular vulnerable to feelings of loneliness. They are gradually emancipating from their family and establish relationships with peers. Among the important predictors of loneliness belong genetic and personal variables and factors of social environment.

To examine predictors of adolescents’ loneliness which are located in family environment. To find out how empathy, emotional relationship and control by both of parents contribute to loneliness of adolescent boys and girls.

We examined 206 adolescents in the age from 10 to 18 years through Basic Empathy Scale, Parenting Style Scale and UCLA Loneliness Scale. Stepwise multiple linear regression analysis was used for data analysis.

The significant predictors of boys’ loneliness in family environment are emotional relationship of mother and affective empathy of father. The significant predictors of girls’ loneliness include emotional relationship and cognitive empathy of father. Parental control is not a significant predictor of adolescents’ loneliness.

Adolescents’ loneliness is largely influenced by factors of family environment. Our study highlights the role of emotional relationship provided by the opposite sex parent. Cold behavior of the opposite sex parent could reduce self-esteem and self-confidence of adolescents. Both could help them establish relationships with peers and people outside family, thus protecting them against loneliness. A significant predictor of boys’ and girls’ loneliness is also empathy of father. We recommend to make use of our findings in clinical practice with adolescents, in family therapy as well as in context of attachment.
