Studies of families with gifted adolescents have revealed conflicting results. Adolescents, mothers, and fathers of 84 families with a gifted adolescent and of 95 families with a non-gifted adolescent evaluated their family system independently. Dependent variables were cohesion, democratic family style (adaptability), organisation, achievement orientation, communication, and intellectual-cultural orientation. Neither statistically nor practically significant relationships between giftedness and family system variables could be observed from the perspectives of the adolescents, the mothers, or the fathers. Contradictory results from other studies can be primarily attributed to their methodological shortcomings, labelling effects, or both. The mean interrater agreement was r = .46 for mothers and fathers, r = .38 for adolescents and mothers, and r = .35 for adolescents and fathers.
