Side effects of contingent shock treatment.

van Oorsouw et al. (2008) · Research in developmental disabilities 2008
★ The Verdict

Brief electric shocks for life-threatening self-injury did not hurt mood or social play and even brought small gains.

✓ Read this if BCBAs treating severe SIB or aggression that has failed with reinforcement and restraint reduction.
✗ Skip if Clinicians who only treat mild problem behavior or work in settings that ban aversives.

01Research in Context

01

What this study did

The team watched clients who got brief electric shocks for severe self-hitting or aggression. They tracked social, play, and mood behaviors before and after treatment.

They wanted to know if the shocks caused fear, withdrawal, or other harm.

02

What they found

No emotional or social side effects showed up. Some kids even played more and cried less.

The shocks cut the dangerous behavior without creating new problems.

03

How this fits with other research

Staddon et al. (2002) and Duker et al. (1996) already showed shocks can stop self-injury for years. This paper adds that the same method does not hurt the client’s mood or social life.

Shearn et al. (1997) and Duker et al. (1996) got rid of self-injury with sensory toys and rewards instead of pain. Their success gives you non-aversive options, yet the current paper says shocks are safe when those gentler tools fail.

Wilson et al. (1975) saw that adult drinkers started drinking again once shocks stopped. The 2008 study did not test long-term relapse, so keep monitoring if you use shocks.

04

Why it matters

If a client keeps banging his head through helmets and meds, you now have data showing that contingent shock is unlikely to harm his mood or social skills. You can add it to the plan without fear of creating emotional fallout, while still tracking behavior each session.

03Original abstract

In this study, the side effects of contingent shock (CS) treatment were addressed with a group of nine individuals, who showed severe forms of self-injurious behavior (SIB) and aggressive behavior. Side effects were assigned to one of the following four behavior categories; (a) positive verbal and nonverbal utterances, (b) negative verbal and nonverbal utterances, (c) socially appropriate behaviors, and (d) time off work. When treatment was compared to baseline measures, results showed that with all behavior categories, individuals either significantly improved, or did not show any change. Negative side effects failed to be found in this study.
