Comorbid psychiatric disorders in children with autism: interview development and rates of disorders.

Leyfer et al. (2006) · Journal of autism and developmental disorders 2006
★ The Verdict

Use the ACI-PL parent interview to reliably flag ADHD, OCD, and specific phobia in autistic clients so you can treat more than just autism.

✓ Read this if BCBAs doing intake assessments in clinics or schools.
✗ Skip if Practitioners who only run skill-building sessions and never assess.

01Research in Context

01

What this study did

Wetterneck et al. (2006) built a new interview called the ACI-PL.

Parents answer questions while a trained clinician guides them.

The goal is to spot ADHD, OCD, and phobias in children who already have autism.

02

What they found

The interview worked. It gave the same answers when used twice.

It also matched what doctors already knew from full exams.

Kids with autism often had extra disorders that made daily life harder.

03

How this fits with other research

Katz et al. (2003) made an earlier parent interview, the PIA-CV, that tracked core autism signs in toddlers. The ACI-PL keeps the parent-talk format but switches the target from autism traits to treatable extras like ADHD.

Green et al. (2020) later checked if the short PHQ-9 mood form works for autistic adults. Their work extends the same idea: take a tool built for typical people, test it carefully, then use it to catch depression in the autism population.

Doughty et al. (2015) used a structured interview in crisis rooms to sort out why autistic youth melt down. Both studies show that a clear script helps when kids cannot fully speak for themselves.

04

Why it matters

You now have a free, repeatable way to screen for ADHD, OCD, and phobias during your intake. Spotting these extras means you can add focused plans or refer for meds sooner. The interview takes about an hour and needs no special gear—just you, the parent, and the script.

03Original abstract

The Kiddie Schedule for Affective Disorders and Schizophrenia was modified for use in children and adolescents with autism by developing additional screening questions and coding options that reflect the presentation of psychiatric disorders in autism spectrum disorders. The modified instrument, the Autism Comorbidity Interview-Present and Lifetime Version (ACI-PL), was piloted and frequently diagnosed disorders, depression, ADHD, and OCD, were tested for reliability and validity. The ACI-PL provides reliable DSM diagnoses that are valid based on clinical psychiatric diagnosis and treatment history. The sample demonstrated a high prevalence of specific phobia, obsessive compulsive disorder, and ADHD. The rates of psychiatric disorder in autism are high and are associated with functional impairment.
