Methods: 356 children recruited from Head Start (58% European American, 25% African American, 17% Hispanic; 54% girls; Mage= 4.59 years) were followed longitudinally from pre-kindergarten through fifth grade. Teachers provided ratings of children's inattentive behavior.
Results:Latent profile analyses of teacher-rated inattention from kindergarten through third grade identified 4 developmental trajectories: 1) stable low (53% of the sample), 2) stable high (11.3%), 3) rising over time (16.4%), and 4) declining over time (19.3%). Children with stable low inattention had the best academic outcomes in fifth grade, children exhibiting stable high inattention had the worst, with the others in between. Self-regulation difficulties in preschool (poor executive function skills; elevated oppositional-aggression) differentiated children with rising versus stable low inattention. Elementary schools characterized by higher achievement differentiated children with declining versus stable high inattention. Boys and children from single parent families were more likely to remain high or rise in inattention, whereas girls and children from dual-parent families were more likely to remain low or decline in inattention.
Conclusions: The current study demonstrated that inattention is characterized by continuities and discontinuities that are meaningfully associated with academic outcomes, as well as with risk and protective factors. It was notable that environmental supports (e.g., schools characterized by high-achieving students, dual-parent families) emerged as the major factors differentiating children who started kindergarten with elevated inattention and improved over time from those who remained highly inattentive. Additionally, the primacy effects of child inattention at school entry on later academic achievement were notable in this study, suggesting the importance of intervening to improve attention problems in early childhood before kindergarten.
