« The longitudinal study reported here addressed three goals. The first goal was to identify and describe different possible teacher-rated trajectories of anxiety from kindergarten to Grade 6. The second goal was to examine the contribution of the children’s behavioral characteristics, as assessed in kindergarten, to the prediction of their trajectories of anxiety during their elementary-school years. The third goal was to determine the possible direct or interactive role of maternal parenting. Sociofamily adversity (including family status, the mother’s education level, and age at birth of first child) served as a control variable based on its known links with both the predictors (i.e., children’s behavioral characteristics, maternal behaviors) and the outcomes (i.e., anxiety; Duchesne et al., 2008; Vitaro et al., 2005). » (p. 364)
« In the current investigation, two hypotheses were derived from the preceding studies on parenting. First, children who have been exposed to maternal warmth and to mothers who have fostered their self-regulation by setting clear limits will have a greater probability of belonging to the lowest anxiety trajectory group (compensatory effect hypothesis). Second, the association between children’s behavioral characteristics and their trajectories of anxiety may be moderated by the quality of maternal parenting to which they have been exposed (protective effect hypothesis). » (p. 364)

« Developmental trajectory analyses allowed us to identify four trajectory groups: low, low-increasing, high-declining, and high anxiety groups. Moreover, multinomial logistic regressions revealed a profile of children at risk of developing high anxiety symptoms (i.e., high group), characterized by sociofamily adversity, inattention, and low prosociality in the classroom. Hyperactivity was also found in this profile, but only for children exposed to a mother who showed little affective warmth. Finally, mothers’ high level of discipline increased the odds of belonging to the high anxiety group. The results are discussed in relation to studies examining the association among anxiety, behavioral characteristics, and parenting during childhood. » (p. 361)
