Differentiation of adolescent activity participation.

The sex typing or lack of it among 133 adolescent activities was investigated. Twenty-seven percent (32) of the activities on an Adolescent Activity Questionnaire showed very clear participation differences for male and female adolescents (11 to 18 years old). The initial two factors extracted in a principal components factor analysis were easily interpreted as feminine and masculine activities. Discriminant function analysis of 15 items from the first three factors yielded an 8-item function on the basis of which every sample member was correctly classified as male or female. Masculine activities included more sports-related activities and activities dealing with mechanics and building, whereas feminine activities were domestic in nature and included more sedentary activities (e.g., reading, writing in diaries).
