The following study asks questions addressing differences in adolescents' l
evels of autonomy as a function of parenting and parental involvement pract
ices and year-end averages. The construct of autonomy addresses the adolesc
ents' psychosocial maturity. Using data from 872 adolescents living in Queb
ec, the authors found that: (a) adolescents' autonomy and more specifically
, work orientation followed by self-reliance and identity, individually con
tributed to the prediction of school grades; (b) parental warmth, supervisi
on, psychological autonomy granting and affective support show a positive r
elationship with work orientation; parent-adolescent interactions on daily
school matters are negatively related to autonomy, work orientation and ide
ntity; (c) autonomy, and mainly, work orientation and self-reliance act as
mediators between parenting, parental involvement and school grades. Thus,
adolescents who perceive their parents as expressing warmth and affective s
upport, as monitoring adequately, and as encouraging them to express indivi
duality within the family are more likely to work harder, to experience sat
isfaction in well-done work, to show initiative, and to succeed better Ban
their peers. Longitudinal studies are needed to examine the possible recipr
ocal relation between adolescents' autonomy and parenting.
