The present research examined the role of maladaptive self-regulatory belie
fs as vulnerability factors for academic and emotional difficulties during
the transition to middle school. A short term longitudinal design was emplo
yed to follow two groups of early adolescents: 187 adolescents who experien
ced a school transition between the fifth and sixth grades, and 142 adolesc
ents who did not experience a school transition between the fifth and sixth
grades. Adolescents completed measures of perceptions of academic control
and importance of academic success, experience of chronic academic strain,
daily school hassles, and depressive symptoms. Teachers reported on student
s' academic engagement, including levels of helpless behavior, effort, and
academic performance. Consistent with the proposed model of self-regulation
, maladaptive self-regulatory beliefs (i.e., decreased perceptions of acade
mic control and importance) predicted individual differences in perceived s
chool-related stress and depressive symptoms over the course of the middle
school transition, but were not associated with academic and emotional diff
iculties in adolescents who remained in a stable school environment. Moreov
er, a self-regulatory sequence was identified proceeding from maladaptive s
elf-regulatory beliefs, to academic disengagement, to enhanced perceptions
of school-related stress, to depressive symptoms. This study bridges prior
theory and research concerning the psychological impact of normative develo
pmental transitions, the developmental context of depression, and the assoc
iations among self-regulatory beliefs, achievement-related behavior, and em
otional experience.
