Assessment & Research

Characterizing Automatically Maintained Self-Injury With the Aberrant Behavior Checklist.

King et al. (2025) · American journal on intellectual and developmental disabilities 2025
★ The Verdict

ABC subscale patterns flag automatically maintained SIB subtypes, guiding you to the right assessment faster.

✓ Read this if BCBAs who assess self-injury in kids or adults with IDD.
✗ Skip if Clinicians who already have full functional-analysis confirmation of social functions.

01Research in Context

01

What this study did

The team used the Aberrant Behavior Checklist (ABC) to look for patterns in self-injury.

They split automatically maintained SIB into finer subtypes instead of treating it as one block.

All participants had intellectual disability or developmental delay.

02

What they found

Overall ABC scores looked the same for social vs. automatic SIB.

When the automatic group was broken down, clear subscale differences popped out.

These patterns give a quick flag for which subtype might be in play.

03

How this fits with other research

Christopher et al. (1991) showed the ABC is reliable with this same population; MacFarland et al. (2025) now push the tool further by using it to screen for function.

Rooker et al. (2018) found that treatment works best after a competing-stimulus assessment; the new ABC signal can tell you which clients need that deeper step.

Christensen et al. (2024) describe high automatic SIB in SYNGAP1-ID; the ABC subscale shortcut could spot these cases without a full functional analysis.

Logan et al. (2000) proved you can test sensory reinforcers experimentally; the checklist offers a fast pre-test so you run those pricey analyses only when the pattern hints at automatic reinforcement.

04

Why it matters

You can open the last ABC on file, scan two subscales, and decide if automatic reinforcement is likely.

When the pattern fits, move straight to competing-stimulus or sensory assessment instead of spinning your wheels in standard social-condition FA sessions.

Less time in the clinic, faster relief for the client, and a clear data trail for the treatment plan.

03Original abstract

Multidimensional variables linked to repetitive behavior, hyperactivity, and mood dysregulation are correlated with the prevalence and severity of self-injurious behavior (SIB) in individuals with intellectual and developmental disabilities (IDD). The purpose of this exploratory study was to examine differences in Aberrant Behavior Checklist (ABC) subscales between individuals with socially maintained SIB and automatically maintained SIB (ASIB). Overall, there were not significant differences in ABC subscale elevations between the SIB and ASIB groups. However, when ASIB was stratified into distinct subtypes, notable differences in subscale elevations were observed. Our results indicate the ABC may have utility for further characterizing the neurobehavioral divergence among individuals with IDD who engage in self-injury.
