Abstract

Naltrexone (NLTX), an opiate receptor antagonist, has been prescribed as a pharmacological intervention for the treatment of self-injurious behavior (SIB). Previous research has investigated NLTX's effects in the absence of information about the role of environmental events related to SIB. This study extended previous analyses by administering NLTX on analog baselines using a double-blind, placebo-controlled reversal design. Pretreatment functional analysis results showed that the SIB of the two participants occurred in more that one assessment condition. For one participant NLTX produced slight reductions in SIB across baseline conditions. The second participant's results showed that NLTX reduced head-slapping occurring during demand sessions, but had no apparent effect on head-banging occurring during alone and demand sessions. These outcomes suggest that NLTX may have function- and/or response-specific treatment effects. The potential utility of this model as a general method for assessing pharmacological interventions, as well as other implications and limitations, are discussed.
