Developmetrics A balanced and short Best Friend Index for children and young adolescents.

This study evaluated a short friendship questionnaire providing a balanced assessment of positive (e.g., support) and negative (e.g., jealousy) friendship features. In addition, associations with indices of adaptive functioning versus psychopathology were tested. The friendship questionnaire was presented to 548 typically developing children and young adolescents (Mage = 11;01 years). Results confirmed validity and independence of the two friendship features, and showed that negative friendship features were uniquely associated with symptoms of psychopathology, whereas both positive and negative features were, in opposite directions, uniquely associated with aspects of socioemotional functioning.
