As with other studies of ego development
in children and adolescents, these adolescents' modal level
of ego development was at the self-protective (E3 level).
The ego development TPR (total protocol
rating) had modest linear associations with measures of ethnic
identity.
Ego development TPR was significantly
related to only a few of the psychological and interpersonal
adjustment measures: depression, negative affect, and social
problems.
". . . there is a reasonable
relationship between ego development and identity strivings
during early adolescence. Specifically, ego development relates
meaningfully to initial ethnic identity exploration in this
sample of American Indian adolescents" (p. 744).
"The data do not support the contention
that higher ego development and ethnic identity levels are ipso
facto more psychologically adjusted, although higher levels
were associated with reduced aggression, social problem behavior,
and peer conflict. Indeed, the higher levels of ego development
in middle school were associated with more internal psychological
distress, including social anxiety, depression, and lagged self-esteem"
(p. 744).
Newman notes the following limitations to the
study:
Because of its relatively small sample
size, it cannot detect small effects (particularly on the upper
end of the ego development scale) and may not generalize to
other ethnicities or even to reservation-dwelling rural Native
American adolescents
The fact that all participants were
self-selecting volunteers may have affected the results.
The fact that the measures were all
self-reporting may have affected the results.
Newman notes that the limitations named above
are tempered by the fact that the findings of this study are
consistent with findings of a great deal of previous empirical
studies as well as with ego development theory.
