Motivation and self-perception profiles and links with physical activity in adolescent girls.

Research shows a decline in participation in physical activity across the teenage years. It is important, therefore, to examine factors that might influence adolescent girl's likelihood of being physically active. This study used contemporary theoretical perspectives from psychology to assess a comprehensive profile of motivational and self-perception variables in 11-16 year old English girls (n=516). A cross-sectional design was employed. Cluster analysis was conducted to (a) map cluster profiles and (b) test whether clusters differed in physical self-worth, global self-esteem, and physical activity. Results revealed a five-cluster solution depicting 40% of the sample as moderately motivated, 30% lowly motivated in two clusters, and 30% highly motivated, also in two clusters. However, differences between clusters on physical activity were quite small. Results show potential areas for intervention to enhance the motivation of adolescent girls for physical activity.
