Pica is a potentially deadly form of self-injurious behavior most frequently exhibited by individuals with developmental and intellectual disabilities. Research indicates that pica can be decreased with behavioral interventions; however, the existing literature reflects treatment effects for small samples (n = 1-4) and the overall success of such…

There is a lack of evidence-based behavioral therapies or pharmacotherapies to treat repetitive behaviors found in autism. Effective behavioral therapies are needed to counter any negative consequences these behaviors may have on the child's early learning and socialization. The purpose of this proof-of-principle study was to test the feasibility…

Coprophagia, the ingestion of fecal matter, occurs among some individuals with developmental disabilities and is associated with a variety of health risks (e.g., diarrhea, intestinal parasites, blood-borne pathogens; Parry-Jones & Parry-Jones, 1992). Studies that have evaluated operant-based treatments of coprophagia have been limited by a lack of…

Some individuals with developmental disabilities and emotional disorders may engage in challenging behavior that can result in the use of aversive procedures and/or seclusion from typically developing peers. They may also engage in low levels of physical activity. One way to decrease challenging behaviors while increasing overall levels of…

The present study was a multisite randomized clinical trial assessing the effects of adding a cognitive-behavioral intervention to positive behavior support (PBS). Fifty-four families who met the criteria of (a) having a child with a developmental disability, (b) whose child displayed serious challenging behavior (e.g., aggression, self-injury,…

For most children, the developmental stage of exploring the world by putting everything, food and non-food items, in or around the mouth begins at birth and ends around 18 months of age. However, for those with developmental disabilities, this tendency may last into adulthood with the ingestion of non-nutritive, non-food items, a disorder called…

We conducted functional analyses of pica for three individuals with varying levels of intellectual disabilities. In addition, two indirect assessment instruments (the "Motivational Assessment Scale [MAS]", and the "Questions About Behavioral Function [QABF]") were also administered to both the parent and teacher of the child…

We reviewed studies involving the treatment of elopement in individuals with developmental disabilities. Systematic searches of three electronic databases, journals, and reference lists identified 10 studies meeting the inclusion criteria. These studies were evaluated in terms of: (a) participants, (b) procedures used to assess elopement, (c)…

The Triple P Positive Parenting Program is a multilevel parenting program to prevent and offer treatment for severe behavioral, emotional, and developmental problems in children. The aim of this meta-analysis is to assess the effectiveness of Triple P Level 4 interventions in the management of behavioral problems in children by pooling the…

In school settings, behavior analysts are often called in to consult on severe behavioral issues that surpass the knowledge, experience, and training of local school personnel. Severe behavior such as aggression to staff, SIB, and property destruction are common severe behavior referrals. The benefits of functional assessments, functional…

Treatment with two setting condition manipulations and use of a visual occlusion helmet was found to decelerate intense screaming by a 16-year-old girl with developmental disabilities. Cranial pressure was found to be the critical element in self-control, and replacing the helmet with a headband was found to be effective in maintaining behavior…

This study of an adolescent with mental retardation and autism found that pica of cigarette butts was maintained in a condition with no social consequences when cigarettes contained nicotine but not when cigarettes contained herbs without nicotine. A procedure based on stimulus control, which reduced cigarette consumption to zero, is described.…

In this paper, we review definitional issues related to stereotypy, behavioral interpretations of stereotypy, procedures for determining operant function(s) of stereotypy, and behavioral interventions for stereotypy. In general, a preponderance of the assessment literature suggests that most forms of stereotypy are maintained by automatic…

The consumption of nonfood items (i. e., pica) frequently occurs in persons with developmental disabilities. Pica may result in the puncture or blockage of the digestive tract, infestation by gastrointestinal parasites, and can interfere with an individuals daily learning, occupational performance, and quality of life. Twenty-six published studies…

By watching and responding to the way a shill answered "yes-no" questions about food items, a developmentally delayed preschool boy greatly improved over his poor base-line "yes-no" answers to these same items. He was also able to give correct answers subsequently during generalization probe sessions. (PS)
