Little is known about the changes in self-perceptions over the course of mi
ddle childhood, despite this being a crucial period for the development: of
the self. This study examined stability and change in children's self-comp
etence and self-esteem in a two-wave longitudinal study of primary school c
hildren. The influence of psychosocial factors, gender, religion/ethnicity
and socio-economic status (SES), on the development of self-perceptions was
also examined. A sample of 110 children completed the Harter Self Percepti
on profile for Children at age 8 and age 11. Analysis of these data indicat
ed considerable stability in children's perceptions of themselves. Ar age i
i, a greater variety of domain-specific self-perceptions was predictive of
global self-esteem, suggesting a more complex view of the self. Additionall
y, between-group differences suggested that girls' global and athletic comp
etence, as well as their confidence in their physical appearance, decreased
over time. Further, children from lower socio-economic backgrounds and tho
se from the minority community in Northern Ireland (Roman Catholics) displa
yed less positive self-perceptions in a number of life domains at both age
11 and age 8. Discussion of these results highlights the influence of socie
tal factors on children's social development and the need to consider the c
ombined effects of psychosocial identities and socio-economic background on
the development of the self.
