Parent and Teacher ADHD Ratings Show Low Agreement, Kappa 0.25 Across 8,796 YouthComparing Parent and Teacher Reports for Diagnosing ADHD in Children

Key Takeaway
Recognize low parent-teacher agreement in ADHD ratings; interpret discrepancies cautiously.

This meta-analysis examined concordance between parent and teacher ratings of ADHD symptoms in children and adolescents under 18 years using DSM-IV/V criteria. The analysis included 8,796 participants across school, community, and clinical settings. The primary outcome was agreement measured by Cohen's Kappa.

Overall parent-teacher agreement was low (Kappa = 0.25, 95% CI 0.18-0.31). Agreement varied by sample setting: school-based samples showed the highest concordance (Kappa = 0.31), followed by community samples (Kappa = 0.27), while clinical samples showed the lowest and non-significant agreement (Kappa = 0.07). Child gender had minimal impact on agreement (boys: Kappa = 0.25; girls: Kappa = 0.32).

The authors note high heterogeneity (I2 = 75.8%) and that limited data precluded a meta-analysis on agreement between parents. No safety data were reported. Funding and conflicts of interest were not reported.

The findings suggest that high levels of discrepancy across informants should be a focus of clinical attention, and discrepancies must be explicitly interpreted in diagnostic decision-making. Clinicians should recognize that parent and teacher reports often diverge, particularly in clinical samples, and should not treat either source as a gold standard.

How this fits prior evidence

This meta-analysis extends prior coverage of ADHD risk factors and comorbidities by focusing on assessment concordance rather than etiology. Previous findings linked excessive screen time (OR 1.56) and sugar-sweetened beverage consumption to increased ADHD risk, and noted that mindfulness-based interventions may improve core symptoms with high heterogeneity. Another prior item reported that ADHD doubles bruxism odds. The current finding that parent-teacher agreement is low (Kappa = 0.25) addresses a gap in understanding diagnostic variability, complementing these risk and treatment studies by highlighting the importance of multi-informant assessment.

Doctors often rely on both parents and teachers to help diagnose ADHD in children. This study looked at hundreds of cases to see how much these two groups agree on the child's behavior and symptoms.

The results showed that parents and teachers do not agree very often. Even though they are both looking at the same child, they often report different levels of symptoms. This means that one person's view might not tell the whole story.

Where the child is observed also changes the results. Teachers and parents agreed more when the children were in a school setting. However, they agreed much less when the children were in a clinical setting. This suggests that the environment where a child is observed can change how symptoms appear.

Because of these differences, doctors should pay close attention when reports from parents and teachers do not match. It is important to talk about these differences during the diagnosis process to get a clearer picture of the child's needs.

What this means for you:
Parents and teachers often disagree on ADHD symptoms, especially in clinical settings, making both views important.

Common questions

How often do parents and teachers disagree about ADHD symptoms?

In this meta-analysis of 8,796 children, overall agreement between parent and teacher ratings was low, with a Cohen's Kappa of 0.25. That means their reports often do not match. Agreement was highest in school samples (Kappa = 0.31) and lowest in clinical samples (Kappa = 0.07).

Does the setting affect how much parents and teachers agree on ADHD?

Yes. The study found that agreement varied by setting. School-based samples had the highest concordance (Kappa = 0.31), community samples were similar (Kappa = 0.27), and clinical samples had the lowest and non-significant agreement (Kappa = 0.07). This suggests where families are assessed may influence how well reports line up.

Does a child's gender change how much parents and teachers agree on ADHD symptoms?

Gender had only a minimal impact. Agreement was slightly higher for girls (Kappa = 0.32) than for boys (Kappa = 0.25). The difference was small, so gender alone does not explain the low overall agreement between parents and teachers.

What should I do if my child's parent and teacher reports of ADHD don't match?

Disagreement is common and does not mean one person is wrong. The study authors say these differences should be a focus of clinical attention. If you are concerned about your child's behavior or attention, talk with your pediatrician or a mental health professional. They can help interpret different reports.

Background/objectivesAccurate diagnosis of attention-deficit/hyperactivity disorder (ADHD) requires multi-informant assessments across different settings, yet consistent agreement between parents and teachers remains challenging. This systematic review and meta-analysis aimed to quantify the level of concordance between parent and teacher ratings of ADHD symptoms in children and adolescents and to examine the moderating effects of child gender and sample settings.MethodsWe conducted a comprehensive search of Web of Science, Embase, and PubMed from 1994 to May 2026(PROSPERO: CRD42024556281). Inclusion criteria encompassed studies assessing ADHD symptoms in individuals under 18 years using DSM-IV/V criteria and reporting Cohen’s Kappa for parent-teacher agreement. A random-effects meta-analysis was performed, with subgroup analyses based on gender and sample settings (clinical, school, community). Heterogeneity was assessed using the I² statistic.ResultsEleven studies involving 8796 participants were included. The overall parent-teacher agreement was low (Kappa = 0.25, 95% CI: 0.18-0.31), with substantial heterogeneity (I² = 75.8%). Subgroup analyses revealed that gender had a minimal impact on agreement levels (boys: Kappa=0.25; girls: Kappa=0.32). However, sample settings significantly moderated agreement: school-based samples showed the highest concordance (Kappa=0.31), followed by community samples (Kappa=0.27), while clinical samples demonstrated the lowest and non-significant agreement (Kappa=0.07).ConclusionsThis meta-analysis confirmed low parent-teacher agreement in ADHD assessments, with the lowest agreement observed in clinical samples. Existing studies also suggest moderate agreement between parents themselves, although the limited data precluded a meta-analysis on this specific comparison. Nevertheless, these findings highlight that high levels of discrepancy across informants should be a focus of clinical attention. When integrating multi-informant data, such discrepancies must be explicitly interpreted, and standardized methods are needed to reconcile them in diagnostic decision-making.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=4556281, identifier CRD4202455628.
