What They Studied
Researchers investigated whether 3 months of participation in the Brain Balance program could reduce attentional difficulties in children and adolescents. The study was authored by Dr. Rebecca Jackson of Brain Balance and Dr. Joshua T. Jordan of the Department of Psychology at Dominican University of California and published by Springer Nature in Humanities and Social Sciences Communications.
Seventy-one participants (aged 4–18 years; 69% male) were assessed before and after the program using the Brown Attention-Deficit Disorder Scales (BADDS), a standardized clinical instrument that measures executive function deficits associated with ADHD. At baseline, participants scored approximately 1.5 standard deviations above the normative BADDS sample, confirming the presence of significant attentional difficulties prior to program enrollment.
The researchers used three complementary statistical approaches to evaluate change. First, a Wilcoxon signed-rank test to determine whether group-level scores changed significantly. Second, the Reliable Change Index (RCI) to evaluate whether each individual participant's improvement exceeded measurement error. Third, logistic regression to identify which participant characteristics predicted reliable change — specifically, whether baseline severity, age, or gender influenced outcomes.
What They Found
Group-Level Improvement: Significant Decline in ADHD Symptoms
Scores on the Brown ADD Scales differed significantly from pre- to post-program, with an average decline of 7 T-score points. The probability of any given Brain Balance participant improving from pre- to post-program was 81%. This represents a meaningful shift on a standardized clinical instrument — the BADDS uses a normative T-score scale where a 7-point improvement moves a child measurably closer to the typical range.
Individual-Level Analysis: The Reliable Change Index
The Reliable Change Index (RCI) applies a stricter standard than group-level statistics. It asks: "Did this specific child's improvement exceed what could be attributed to measurement error alone?" The results broke down as follows:
| Outcome Category | Number of Participants | Percentage |
|---|---|---|
| Achieved reliable improvement | 36 | 49.3% |
| Improved but below RCI threshold | 34 | 46.6% |
| Reliable deterioration | 3 | 4.1% |
Nearly half of all participants (49.3%) met the strict threshold for clinically reliable change. An additional 46.6% improved but did not reach the RCI threshold — which does not mean they didn't improve, only that their improvement, while real at the group level, could not be confirmed as individually reliable at the 95% confidence level. The inclusion of the three participants (4.1%) who showed reliable deterioration reflects the study's commitment to transparent reporting.
Severity Predicts Response: Who Benefits Most
Logistic regression analysis revealed that baseline BADDS score was a significant predictor of reliable change. For every one-unit increase in baseline T-score (indicating more severe ADHD symptoms), the odds of achieving reliable improvement increased by 15%. In practical terms: children who entered the program with the most pronounced attentional difficulties were the most likely to experience meaningful, measurable improvement.
Age was also a significant predictor — younger participants were more likely to achieve reliable change than older participants. Gender was not a significant predictor of outcomes.
Why It Matters
An Established Clinical Instrument, Published by Nature
Two aspects of this study strengthen its credibility beyond the findings themselves. First, the Brown ADD Scales are a widely used, independently developed clinical instrument — not a Brain Balance-created tool. The BADDS was developed by Dr. Thomas E. Brown at Yale University and is used in clinical practice worldwide for assessing executive function deficits in ADHD. This means the outcomes were measured on an instrument with independent normative data and established psychometric properties.
Second, the study was published by Springer Nature in Humanities and Social Sciences Communications, a journal within the Nature portfolio. Nature is one of the most recognized scientific publishing brands globally, and its peer-review standards are well-established.
The finding that baseline severity predicts response is consistent across multiple Brain Balance studies. The larger Frontiers in Psychology study (N=4,041) found the same pattern using a different assessment tool: children with more severe developmental difficulties at baseline showed larger effect sizes and a higher percentage of reliable change. The convergence of this finding across different instruments, different sample sizes, and different outcome domains strengthens the evidence that the pattern is genuine rather than a statistical artifact.
The 81% improvement rate provides a practical answer to the question parents most want answered: "Is my child likely to improve?" While 49% achieved the strict threshold of reliable change, the broader finding is that more than four in five participants showed some degree of improvement on a standardized ADHD measure. The 4.1% deterioration rate is important to report transparently — it means 96% of participants either improved or stayed the same.
This study also contributes to the growing body of evidence on nonpharmacological approaches to ADHD in children. The researchers note that while stimulant medication remains the most widely used treatment, side effects such as appetite suppression, sleep disruption, and mood changes lead many families to seek alternative or complementary approaches. This study provides peer-reviewed evidence that a structured multimodal program can produce measurable ADHD symptom improvement in the majority of participating children.
Study Limitations
This was a single-group pre-post study with no control group, meaning improvements cannot be definitively attributed to the program versus natural maturation, regression to the mean, placebo effects, or concurrent interventions. The sample size (N=71) was moderate, and outcomes relied on parent-reported measures. Participants' specific clinical diagnoses were not available, and the study did not include a follow-up assessment to determine whether improvements were sustained after program completion. Randomized controlled trials with independent outcome measures and longer-term follow-up are needed to confirm these findings.
