The treatment of severe self-injurious behavior by the systematic fading of restraints: effects on self-injury, self-restraint, adaptive behavior, and behavioral correlates of affect

A Meta-Analysis of Single-Case Research on Applied Behavior Analytic Interventions for People With Down Syndrome

This systematic review evaluates single-case research design studies investigating applied behavior analytic (ABA) interventions for people with Down syndrome (DS). One hundred twenty-five studies examining the efficacy of ABA interventions on increasing skills and/or decreasing challenging behaviors met inclusion criteria. The What Works Clearinghouse standards and Risk of Bias in N-of-1 Trials scale were used to analyze methodological characteristics, and Tau-U effect sizes were calculated. Results suggest the use of ABA-based interventions are promising for behavior change in people with DS. Thirty-six high-quality studies were identified and demonstrated a medium overall effect. A range of outcomes was targeted, primarily involving communication and challenging behavior. These outcomes will guide future research on ABA interventions and DS.

Emerging Evidence from Single-Subject Research in the Field of Deaf-Blindness

Professionals in the field of deaf-blindness are challenged to use instructional practices that have been tested using experimental methodology. Single-subject design has been examined as a form of research that assists in substantiating practice. In a review of the literature, the authors identified 54 single-subject studies from 1969 to 2006 that provided emerging evidence for practitioners.

Self-Injurious Behavior in Children With Developmental Disabilities: A Systematic Review of Behavioral Intervention Literature

We reviewed single-case research studies examining the effects of behavioral interventions for self-injurious behavior (SIB) in young children with autism and developmental disabilities. Systematic searches of electronic databases, journals, and reference lists identified 46 studies (66 participants younger than the age of 12) meeting inclusion criteria. Studies were examined based on (a) participant demographics, (b) topography and function of SIB, (c) type of functional behavior assessment (FBA), (d) intervention procedures and outcomes, and (e) experimental design and measurement. Intervention strategies were categorized as antecedent manipulations, teaching behavior, consequence-based procedures, and/or extinction procedures. Positive outcomes were reported for 78% of participants in the reviewed studies and 88% of the participants were diagnosed with autism. Results suggest the effectiveness of behavioral interventions to decrease SIB for young children with disabilities; however, the frequent use of packaged interventions without component analysis limits the conclusiveness of any treatment recommendation. Suggestions for future research are discussed.

Further investigation of a rapid restraint analysis

Research related to the use of mechanical restraint devices (e.g., arm splints) has been limited despite the frequency with which they are used in the clinical treatment of severe and dangerous self-injurious behavior (SIB). Wallace, Iwata, Zhou, and Goff () used a rapid restraint analysis (RRA) to evaluate the effects of different levels of arm-splint flexion on rates of hand-to-head SIB and adaptive behavior. The goal of the current study was 3-fold: (a) to extend previous research on RRA by reporting RRA results for 10 participants and investigating post-RRA outcomes, (b) to investigate whether the RRA might have the potential to eliminate the need for restraint fading altogether for some individuals, and (c) to investigate whether the RRA might help to identify a starting point for restraint fading for individuals for whom fading is necessary. Results suggested that the RRA helped to eliminate the need for restraint fading for 6 participants. With respect to the identification of a starting point for restraint fading, results were mixed. Overall, 8 of the 10 participants were discharged from the inpatient unit at a less restrictive level of flexion or at the same level of flexion identified by the RRA. Implications for adoption of the RRA are discussed.

Initiatives to reduce the use of seclusion and restraints on people with developmental disabilities: a systematic review and quantitative synthesis

Contrary to the expectations articulated in public policy, restrictive interventions are commonly used in support services for people with developmental disabilities. This systematic review and quantitative synthesis was undertaken to investigate whether the use of seclusion and restraints on people with developmental disabilities can be reduced. Searches of the Academic Search Complete, CINAHL, MEDLINE, and PsycINFO electronic databases returned 7226 records, of which 11 met the inclusion criteria for this review. A further 3 papers were obtained through scanning the reference lists of those articles included from the initial literature search. All 14 studies were single-subject designs focusing on initiatives to reduce physical or mechanical restraint. Between the baseline and intervention phases, there were mean reductions in the frequency and duration of restraint use of 79% (SD=21%, n=13 subjects from 7 studies) and 45% (SD=58%, n=10 subjects from 6 studies), respectively. For studies in which restraint use to manage agitation and aggression was targeted, there was a 79% (SD=21%, n=13 subjects from 7 studies) decrease in the frequency and a 28% (SD=67%, n=6 subjects from 3 studies) reduction in the duration of restraint. With respect to studies in which restraint use to prevent self-harm was targeted, there was a 71% (SD=34%, n=4 subjects from 3 studies) reduction in restraint use. Effect sizes were calculable, using non-overlap approaches, for 9 of the 14 studies. The magnitudes of the effect sizes suggest that, on average, the interventions were effective in reducing the use of restraints. The effects generated in studies where restraint use for self-harm was targeted were typically more pronounced than those in which restraint use for agitation and aggression was addressed. There were broad variations, however, in the percentage reductions in restraint use and in the magnitudes of the effect sizes. Although the findings of this review are encouraging, more research is needed, in which greater attention must be paid to rigorous research design, application, and analysis.

The association for behavior analysis international position statement on restraint and seclusion

A task force authorized by the Executive Council of the Association for Behavior Analysis International (ABAI) generated the statement below concerning the techniques called restraint and seclusion. Members of the task force independently reviewed the scientific literature concerning restraint and seclusion and agreed unanimously to the content of the statement. The Executive Council accepted the statement, and it was subsequently approved by a two-thirds majority vote of the general membership. It now constitutes official ABAI policy. The position statement is posted on the ABAI Web site (www.abainternational.org/ABA/statements/RestraintSeclusion.asp). The purpose of the position statement is to provide guidance to behavior analysts and other professionals interested in the position of ABAI on these controversial topics. In extreme cases, abuses of procedures erroneously used in the name of behavior analysis are not defensible. On the other hand, behavior analysts acting ethically and in good faith are provided with guidelines for sound and acceptably safe practice. To the extent that behavior-analytic positions influence public policy and law, this statement can be presented to officials and lawmakers to guide informed decision making. At the conclusion of the document, a bibliography is provided of articles and presentations considered by one or more task force members in developing the position statement.

The expression and assessment of emotions and internal states in individuals with severe or profound intellectual disabilities

The expression of emotions and internal states by individuals with severe or profound intellectual disabilities is a comparatively under-researched area. Comprehensive or standardized methods of assessing or understanding the emotions and internal states within this population, whose ability to communicate is significantly compromised, do not exist. The literature base will be discussed and compared to that applicable to the general population. Methods of assessing broader internal states, notably depression, anxiety, and pain within severe or profound intellectual disabilities are also addressed. Finally, this review will examine methods of assessing internal states within genetic syndromes, including hunger, social anxiety, and happiness within Prader-Willi, Fragile-X and Angelman syndrome. This will allow for identification of robust methodologies used in assessing the expression of these internal states, some of which may be useful when considering how to assess emotions within individuals with intellectual disabilities.

Restraint and self-injury in people with intellectual disabilities: a review

Most of the recent debate concerning the ethics of physical interventions has focused on the management of aggressive and destructive behaviours, neglecting the management of self-injurious behaviour. This is an important omission, given the extremely serious consequences that can arise from this form of challenging behaviour. The present article reviews types of restraint used to manage self-injury, prevalence of use, and main and side effects of restraint use. It describes some good practice standards and highlights the need for further research and debate in this complex area.

Functional analysis and intervention to reduce self-injurious and agitated behavior when removing protective equipment for brief time periods

The authors conducted studies that were designed to maintain low levels of hand-to-head self-injury when protective equipment was removed (i.e., rigid arm sleeves and a protective helmet) for brief time periods with an individual with profound intellectual disabilities. A series of assessments was first conducted of a topographically similar form of behavior to self-injury when the person was wearing protective equipment (i.e., hitting helmet with rigid arm sleeves). Results of these assessments indicated that head hitting (with equipment) was not sensitive to social consequences (Study 1) but that it was reduced substantially when the individual had access to items that produced vibration or vibration and sound (Study 2). A treatment protocol that included items that produced vibration and vibration with sound produced substantial reductions in attempts at self-injury and agitation when protective equipment was removed for brief time periods (Study 3).
