Functional analysis methodology focuses on the identification of variables that influence the occurrence of problem behavior and has become a hallmark of contemporary approaches to behavioral assessment. In light of the widespread use of pretreatment functional analyses in articles published in this and other journals, we reviewed the literature in an attempt to identify best practices and directions for future research. Studies included in the present review were those in which (a) a pretreatment assessment based on (b) direct observation and measurement of (c) problem behavior was conducted under (d) at least two conditions involving manipulation of an environmental variable in an attempt (e) to demonstrate a relation between the environmental event and behavior. Studies that met the criteria for inclusion were quantified and critically evaluated along a number of dimensions related to subject and setting characteristics, parametric and qualitative characteristics of the methodology, types of assessment conditions, experimental designs, topographies of problem behaviors, and the manner in which data were displayed and analyzed.

Functional analysis of problem behavior: a review

A randomized trial was conducted to test the efficacy and sufficiency of parent-child interaction therapy (PCIT) in preventing re-reports of physical abuse among abusive parents. Physically abusive parents (N=110) were randomly assigned to one of three intervention conditions: (a) PCIT, (b) PCIT plus individualized enhanced services, or (c) a standard community-based parenting group. Participants had multiple past child welfare reports, severe parent-to-child violence, low household income, and significant levels of depression, substance abuse, and antisocial behavior. At a median follow-up of 850 days, 19% of parents assigned to PCIT had a re-report for physical abuse compared with 49% of parents assigned to the standard community group. Additional enhanced services did not improve the efficacy of PCIT. The relative superiority of PCIT was mediated by greater reduction in negative parent-child interactions, consistent with the PCIT change model.

Repetitive behaviour is widely known to be one of three core and defining features of autism (ICD-10, World Health Organisation, 1990; DSM-IV, American Psychiatric Association, 1994). Any clinician who is told that a child repetitively flaps his arms, spends hours lining up Lego bricks, will not tolerate changes in routine, and has a peculiar fascination with the many varieties of electric fan available on the market will, before hearing anything about the social functioning or communicative abilities of that child, be deeply suspicious that the child is autistic. However, the literature on repetitive behaviour in autism reveals several paradoxes and inconsistencies. First, given the significant challenge that this class of behaviour can pose, the literature devoted to the study of this behaviour in autism is relatively small in comparison with the extensive literature on other aspects of autistic symptomatology. Whilst certain classes of repetitive behaviour have been described as nonspecific to autism (e.g. Prior & Macmillan, 1973), others have been suggested to be of particular significance to the disorder (e.g. U. Frith, 1989; Kanner, 1943; Wing & Gould, 1979). Finally, although repetitive behaviour is commonly defined as behaviour with no obvious goal or function (e.g. Hutt & Hutt, 1970), much of the literature concerning repetitive behaviour in autism has sought to explore what function this behaviour serves.The aim of this Annotation is to provide a review of what is known about repetitive behaviour in autism, its specificity to the syndrome, and the functions or mechanisms that might underlie this behaviour at the psychological level.

Reliability and validity data are reported for an instrument designed to identify variables maintaining self-injurious behavior. The Motivation Assessment Scale (MAS) is a 16-item questionnaire that addresses the situational determinants of self-injurious behavior in persons with autism and other developmental disorders. The reliability study indicated that teachers of 50 developmentally disabled persons could agree on the variables presumably maintaining their student's self-injury (interrater reliability), and that they would be in agreement again 30 days later (test-retest reliability). The validity study indicated that teacher's ratings on the MAS of 8 subjects' self-injury predicted how their students would behave in analogue situations. Specifically, the MAS predicted the subjects' self-injurious behavior in situations with decreased adult attention, with increased academic demands, with restricted access to tangibles, and in unstructured settings. The MAS is presented as an alternative or adjunct to more formal functional analyses in efforts to identify the variables controlling self-injurious behavior.

Identifying the variables maintaining self-injurious behavior

It has been suggested that people engage in nonsuicidal self-injury (NSSI) because they (a) experience heightened physiological arousal following stressful events and use NSSI to regulate experienced distress and (b) have deficits in their social problem–solving skills that interfere with the performance of more adaptive social responses. However, objective physiological and behavioral data supporting this model are lacking. The authors compared adolescent self-injurers (n 62) with noninjurers (n 30) and found that self-injurers showed higher physiological reactivity (skin conductance) during a distressing task, a poorer ability to tolerate this distress, and deficits in several social problem–solving abilities. These findings highlight the importance of attending to increased arousal, distress tolerance, and problemsolving skills in the assessment and treatment of NSSI.

The psychotic speech of autistic and other developmentally disabled children can be defined as words or phrases that are intelligible, but appear out of context. In the present investigation we conducted an analysis of the psychotic speech of a 9-year-old autistic boy. Three experiments were constructed to determine the functional significance of this child's psychotic speech and a method of intervention. The first study involved an analysis of the role of adult attention and task demands in the maintenance of psychotic speech. When task demands were increased, the frequency of psychotic speech increased. Varying adult attention had no effect on psychotic speech. We then performed a second analysis in which the consequence for psychotic speech was a 10-second time-out. Psychotic speech increased, suggesting that it may have been maintained through escape from task demands. Finally, the third experiment involved teaching an appropriate escape response (“Help me”). Psychotic speech was greatly reduced by this intervention. Thus, teaching an appropriate equivalent phrase proved to be a viable alternative to interventions using aversive consequences. The present study represents the first observation that psychotic speech may serve to remove children from unpleasant situations and also introduces a nonaversive intervention for this behavior.
