ABP Developmental-Behavioral Pediatrics common mistakes
ABP Developmental-Behavioral Pediatrics · Understand the traps and how to avoid them.
Scores a toddler's development at chronological age only, so a 22-month-old born at 28 weeks is labelled globally delayed, or the opposite - the clinician corrects one domain in the note and forgets to correct the next.
The calendar age in the chart is what almost every published screener asks for, and the correction arithmetic (weeks preterm subtracted from chronological age) is easy to defer when a visit is running late.
What to do instead
State the corrected age in the header of the report and score motor, language and cognitive milestones against it through 24 months, reserving the label 'delayed' for failure at corrected age; still flag children who fail both ways, since correction reduces but does not erase risk.
Reassures a family that an 18-month-old with no words, or a 27-month-old with no word combinations, is a 'late talker' who will grow out of it, and schedules a recheck in six months instead of arranging audiology and a speech evaluation.
Variation in when children talk is genuinely wide, and the wish to avoid alarming parents leads clinicians to over-apply the benign late-bloomer story rather than the red-flag thresholds.
What to do instead
Anchor on published red flags: no babbling by 9 months, no back-and-forth gestures such as pointing or waving by 12 months, no single words by 16 months, no two-word phrases by 24 months, any loss of skill at any age. Each triggers audiologic testing plus speech-language referral, not watchful waiting.
Diagnoses ADHD in a 3-year-old and starts a stimulant on the strength of one parent-completed rating scale, without gathering a second setting's report or examining sleep, hearing, trauma and developmental delay as alternatives.
The onset-before-age-12 criterion in DSM makes ADHD feel age-agnostic, and high activity plus short attention are hard to distinguish from normal preschool behaviour without a developmental frame.
What to do instead
Treat ADHD as a diagnosis for age 4 and older; below 6 require pervasive impairment across settings from at least two informants and exclude sleep problems, hearing loss, maltreatment, anxiety and language or developmental disorder. For ages 4 to 5, behavioural parent training is first-line, with medication reserved for persistent moderate-to-severe impairment.
Attributes a 5-year-old's irritability, stomach aches, sleep refusal and withdrawal from peers to a phase, and never asks about mood or anxiety because 'children that young don't get depressed'.
Preschool depression presents through irritability, somatic complaints and repetitive play themes rather than a verbalised sad mood, and clinicians carry an adult template that mismatches the presentation.
What to do instead
Ask caregivers directly about sad or irritable mood, anhedonia, sleep, appetite, separation distress, regression and trauma exposure, and use observation of play and affect. Refer for dyadic or CBT-based parent-child treatment rather than reassurance alone.
Withholds or delays genetic testing in a child with global delay, intellectual disability or autism because the dysmorphic features are subtle, ordering only a karyotype or relying on clinical gestalt.
The phenotype is often non-specific, and trainees assume a genetic answer requires an obvious syndrome before testing is warranted.
What to do instead
Offer chromosomal microarray plus fragile X (FMR1) testing as the first-tier workup for unexplained developmental delay, intellectual disability or autism, regardless of dysmorphism, and escalate to exome or genome sequencing when tier one is negative. Add targeted testing for specific phenotypes such as MECP2 in a girl with regression.
Documenting a child's loss of words, waving or eye contact as shyness or a temporary regression, with no change in urgency or referral pathway.
Regressions are heavily diluted by the many children who plateau rather than lose skills, and naturalistic developmental behavioural intervention can look like a plateau to a family.
What to do instead
Treat loss of language or social skills at any age as a red flag requiring prompt evaluation for autism, hearing loss, epileptic encephalopathy such as Landau-Kleffner and, when other skills decline, neurodegenerative disease; obtain EEG or genetics as the history dictates rather than scheduling routine follow-up.
Uses a screening instrument outside the age band or population it was validated for - for example applying the M-CHAT-R/F to a 12-month-old - and then treats a negative screen in a high-risk child as definitive, omitting further evaluation.
Screeners are convenient and numeric, and clinicians often read the total score without consulting the validation population or the follow-up algorithm attached to a positive result.
What to do instead
Match each tool to its validated age range and informant, apply the required follow-up interview or second stage before referral, and remember that a screen shifts probability but never diagnoses. A high-risk child (preterm, known syndrome, sibling with autism, caregiver concern) moves to diagnostic assessment regardless of screen result.
Establishes intellectual disability from an IQ score alone, or conversely labels a child with a normal IQ and weak reading as delayed, without measuring adaptive behaviour in conceptual, social and practical domains.
Psychoeducational reports foreground the IQ number, and adaptive measures take time and a caregiver interview that a busy clinic session discourages.
What to do instead
Require deficits in both intellectual and adaptive functioning, with onset in the developmental period, before diagnosing intellectual disability; obtain a standardised adaptive measure such as Vineland-3 or ABAS-3 and corroborate with school and caregiver report. Distinguish specific learning disability and developmental language disorder, where adaptive skills are typically preserved.
Tells a parent 'come back when he is 3' or refers to the school district for a 2-year-old, delaying services through an age-eligibility mismatch between early intervention and preschool special education.
The referral systems overlap in name and purpose, and clinicians are often unsure which programme accepts children under 3 versus 3 and older.
What to do instead
Refer children under 3 to IDEA Part C early intervention (family-centred, natural environments) and children 3 and older to Part B preschool or school-age special education, with written documentation of the developmental concern. Track the referral and ask the family at follow-up whether an evaluation actually occurred.
Writes the same template recommendation for every child with autism or developmental delay - a fixed weekly quantity of one therapy type - with no reassessment date and no reference to the family's priorities and daily routines.
Templates feel efficient and are copied forward between visits, and intervention intensity is easy to specify without knowing the evidence base for different models or what the family can sustain.
What to do instead
Match intervention to the child's age, profile and home context: naturalistic developmental behavioural models such as ESDM or JASPER and parent-mediated coaching for young children, behavioural parent training for preschool disruptive behaviour, and school-based supports for older children. Set measurable goals, a review interval and a plan to escalate when goals are not met.
