This paper will report on a case study involving an adolescent female with severe, high frequency (6k-9k per month), chronic self-injury. Co-diagnosed with mental retardation and autism, functional analyses indicated that she was intensely stressed by any type of transition or demand, and was also highly dependent on self-restraint. Application for a trial of electro-aversive (faradic) stimulation led, on one hand, to a host of concurrent and sequential behavioral, pharmacological, and medical interventions, all of which failed to abate her self-injury. Initiation of faradic stimulation quickly reduced rates of self-injury and brought about extraordinary positive effects and stabilization of behavior. Subsequently, acute ear infections led to a resurgence of self-injury within an eight-month period, and this relapse was futher aggravated by a number of technical problems, including her marked dependence on the electro-aversive equipment. Continuation of the therapeutic trial again reduced self-injury rates, albeit at a much slower rate. Discussion of these results will focus on some of the variables that facilitate or counteract behavioral suppression in applied settings.
