Assessment & Research

Is it possible to assess the impact of abuse on children with pervasive developmental disorders?

Howlin et al. (1995) · Journal of autism and developmental disorders 1995
★ The Verdict

Sudden, dated behavior jumps in nonverbal youth can signal abuse—trust parent timelines and cross-check records.

✓ Read this if BCBAs working with nonverbal or minimally verbal students in schools or day programs.
✗ Skip if Clinicians serving only highly verbal adults with no trauma history.

01Research in Context

01

What this study did

The team looked back at school records of kids with autism. They matched dates of reported abuse to later behavior notes.

Parents gave timelines of when they first saw new problem behaviors. The goal was to see if abuse left a clear footprint.

02

What they found

Behaviors like screaming, hitting, or withdrawal spiked right after the documented abuse. The pattern held across several children.

Even non-speaking kids showed changes parents could name and dates could prove.

03

How this fits with other research

Brenner et al. (2018) later counted more trauma signs in a bigger inpatient group. They found the same link: abuse first, behavior surge second.

Gilmore et al. (2022) added that when parents themselves carry PTSD, the abuse rate in the child’s history is almost three times higher. This backs the idea that parent report is a valid starting clue.

Soylu et al. (2013) looked at kids with intellectual disability instead of autism. Both studies used file review and saw worse abuse effects in children who could not speak up.

04

Why it matters

You can treat sudden behavior change as a red flag even when the child can’t talk. Ask parents for the day the spike started, then check school incident logs. If the dates line up, start trauma screening and safety planning right away.

03Original abstract

Although it is now recognized that children may exhibit widespread symptoms of stress following exposure to abuse or neglect, the impact of traumatic experiences on children with pervasive developmental disorders has received little attention. The present paper describes a strategy devised to assess the long-term effects of abuse on a group of children who had attended a specialist autistic school where physical and emotional mistreatment of pupils was well documented. Because most of the children had very limited communication skills, the evidence relied heavily on retrospective parental reports. Despite the problems inherent in using such data it was possible to derive reliable measures that could be used to test hypotheses about predicted patterns of behavioral change, based on work with other children who have been abused. In most cases, too, parental reports could be corroborated by information from other sources. Consistent patterns in both the nature and timing of behavioral disturbances were found, which seemed to relate specifically to the period of abuse at the school.
