This study examined the longitudinal associations among maternal child-based worth, perceived maternal achievement-oriented psychological control, and children's academic contingent self-worth over a one-year period in 274 Chinese children. Results showed that, after the autoregressive effects were controlled, higher levels of maternal child-based worth longitudinally predicted higher levels of perceived maternal achievement-oriented psychological control. Higher levels of perceived maternal achievement-oriented psychological control at an earlier time point were also linked to higher levels of children's academic contingent self-worth later. However, earlier levels of children's academic contingent self-worth did not predict their perceptions of maternal psychological control longitudinally. The findings suggest that parents should be aware that their own contingent self-worth may be transferred from one generation to another through maladaptive parenting practice. They are advised not to over-identify with the wins and losses of their children and to consider whether they may have stepped over the autonomy of children inadvertently.
