Abstract
This paper described the results and properties of the Strengths Scale, and some sex differences in various types of strength. Boys tended to see themselves as strong in sport, confidence, popularity, having lots of hobbies and to be attractive. Girls saw themselves as reliable, kind, independent and affectionate. Regression analysis suggested that boys' strengths depended upon parent, peer and school attachment, part-time work and the number of physical activities with which they were involved. Girls' strengths were best predicted by parent attachment and the number of physical activities in which they were involved.
