The gender self-concept profiles of 128 adolescents (107 males) whose persi
stent behaviour problems led to suspension from school were investigated. E
stablishing the students' percentile ratings in the 11 subscales of the Sel
f-Description Questionnaire overcame previous methodological weaknesses. Fo
r boys and girls Physical Appearance, Opposite-sex Relationships, and Hones
ty and Trustworthiness were in the average range, but Parent Relationships,
General Self, and General School self-concepts were low. Only girls were l
ow for Same-sex Relationships and Emotional Stability. The profiles suggest
that boys' antisocial behaviours are associated with striving for a mascul
ine self-image, but girls' antisocial behaviours are associated with greate
r social marginalisation. The issues of multifocused interventions, prosoci
al role models. the particular needs of girls, and the relationship between
self-control, self-enhancement, and reputation enhancement theories are di
scussed.
