The Ecology of ADHD in the Schools

The student-teacher relationship and ADHD symptomatology: A meta-analysis

Children with attention-deficit/hyperactivity disorder (ADHD) typically experience significant academic and social impairments, including problem behaviors in the classroom. Existing research suggests students who present with ADHD symptoms are more likely to have relationships with their teachers that are low in closeness and high in conflict. However, research about the quality of relationships between teachers and students with ADHD symptoms remains quantitatively un-synthesized. The present meta-analysis quantitatively describes the overall quality of student-teacher relationships for children who present with ADHD symptoms according to the relational dimensions of closeness and conflict. Database searches of PsycInfo, ERIC, and ProQuest (theses and dissertations) were conducted to collect a sample of 27 quantitative studies for statistical analyses. A total of 47 effect sizes (N = 17,236) were included in the analyses. Results confirm the trends seen in the literature. Children with symptoms of ADHD tended to have relationships with their teachers that were low in closeness (r = -0.170) and high in conflict (r = 0.414). Additionally, eight moderator analyses were conducted (i.e., grade level, informant types, informant consistency, sample type, reported comorbidity, gender, and ADHD presentation) to assess their effect on the link between ADHD symptoms and student-teacher relationship quality. The results of this meta-analysis provide insight into the quality of relationships that students who exhibit ADHD symptoms form with their teachers also may inform intervention programs that aim to best support students.

The Effectiveness of Daily Behavior Report Cards for Children With ADHD: A Meta-Analysis

Objective: This meta-analysis examined group-design studies investigating the effectiveness of Daily Behavior Report Cards (DBRC) as a school-based intervention to manage the classroom behavior of students with ADHD. Methods: A search of three article databases (PsycINFO, ERIC and Medline) identified seven group design evaluations of DBRC interventions. This meta-analysis included a total of 272 participants, with an average age of 7.9 years old. Three of the studies compared a control group to a treatment group with randomized group assignment, one study compared a control group to three treatment groups, two studies compared pre-and post-treatment scores in the same group, and one study compared pre-and post-treatment results of two intervention groups without random assignment. Dependent measures for these studies were teacher ratings (n = 5) and systematic direct observation of student academic and social behaviour (n = 2). Standardized mean differences (Hedge's g) were calculated to obtain a pooled effect size using fixed effects. Results: DBRCs were associated with reductions teacher-rated ADHD symptoms, with a Hedge's g of 0.36 (95% CI: 0.12-0.60, z=2.93, p ≤ .005) with low heterogeneity (Q-value: 2.40, I² = 0.00). This result excluded two studies that used observational coding instead of standardized tests to evaluate the effects of the intervention. A moderator analysis indicated that the effect size for systematic direct observation was large (Hedge's G = 1.05[95% CI: 0.66-1.44, z=5.25, p ≤ .00]), with very high heterogeneity (Q-value: 46.34, I²: 93.53). A second moderator analysis found differences in the effects of DBRCs for comorbid externalizing symptoms with an overall effect size of 0.34 (95%CI: -0.04-0.72, z=1.76 p =0.08) with high heterogeneity (Q-value: 3.98, I²: 74.85). Conclusions: DBRCs effectively reduce the frequency and severity of ADHD symptoms in classroom settings. Additionally, they have a significant effect on co-occuring externalizing behaviors. It appears that systematic direct observation may be a more sensitive measure of treatment effects compared to teacher ratings of ADHD symptoms.
