Longitudinally Predicting Behavioral Challenges From Executive Functioning in Youth With Down Syndrome.
Weak working memory today signals caregiver-reported inattention six months later in Down syndrome.
01Research in Context
What this study did
Soltani et al. (2025) tracked youth with Down syndrome for six months.
They tested working memory and inhibition at the start.
Caregivers rated inattention, rule-breaking, and aggression at both time points.
What they found
Kids with weaker working memory later showed more inattention.
The link stayed strong even after accounting for baseline behavior.
Inhibition also predicted later rule-breaking and aggression.
How this fits with other research
Kaufman et al. (2010) and Borella et al. (2013) already showed broad executive-function deficits in Down syndrome.
Amanallah now shows these deficits forecast real-world behavior months ahead.
Visser et al. (2017) found childhood self-regulation predicts adult independence.
Amanallah shortens the lens, proving six-month prediction is possible.
Why it matters
Screen working memory and inhibition now to spot kids who may soon struggle with attention or compliance.
Add visual cues, shorter instructions, or pre-teach routines for those with low scores.
Share the brief data with teachers so they can plan extra supports before problems grow.

03Original abstract
This study explored how caregiver-reported executive functioning domains, assessed by the BRIEF2 at baseline, predicted behavioral challenges reported by caregivers using the CBCL six months later. The sample included 94 youth with Down syndrome, aged 6 to 18 years. Results of hierarchical regression analyses revealed that, after controlling for the effect of IQ, working memory significantly predicted inattentive behaviors, inhibition significantly predicted rule-breaking behaviors, and both inhibition and emotional control significantly predicted aggressive and externalizing behaviors. After controlling for baseline behaviors, only working memory persisted as a significant predictor of inattentive behaviors measured six months later. The findings are discussed by referring to the relevant theories and research and providing clinical implications and recommendations for further studies.
