The motivating operation and negatively reinforced problem behavior: a systematic review.

The concept of motivational operations exerts an increasing influence on the understanding and assessment of problem behavior in people with intellectual and developmental disability. In this systematic review of 59 methodologically robust studies of the influence of motivational operations in negative reinforcement paradigms in this population, we identify themes related to situational and biological variables that have implications for assessment, intervention, and further research. There is now good evidence that motivational operations of differing origins influence negatively reinforced problem behavior, and that these might be subject to manipulation to facilitate favorable outcomes.

Towards the prevention of behavioural and psychiatric disorders in people with intellectual disabilities.

Intervention for behavioural and psychiatric disorders in people with intellectual disabilities often only takes place once these conditions are well established and more resistant to change. As an alternative, this paper promotes a public health prevention model and maps out opportunities for intervention at primary, secondary and tertiary levels. The resulting model is partly derived from generic research into these issues and partly on specific evidence on interventions for people with intellectual disabilities; it also contains more theoretical considerations.

Assessing the social acceptability of the functional analysis of problem behavior.

Although the clinical utility of the functional analysis is well established, its social acceptability has received minimal attention. The current study assessed the social acceptability of functional analysis procedures among 10 parents and 3 teachers of children who had recently received functional analyses. Participants completed a 9-item questionnaire, and results suggested that functional analysis procedures were socially acceptable.

An indirect examination of the function of problem behavior associated with fragile X syndrome and Smith-Magenis syndrome.

Fragile X syndrome (FXS) and Smith-Magenis syndrome (SMS) are associated with a number of specific topographies of problem behavior. Very few studies have examined the function served by problem behavior in these groups. Using the Questions About Behavioral Function scale Matson and Vollmer (User's guide: questions about behavioral function (QABF).

Examining the function of problem behavior in fragile X syndrome: preliminary experimental analysis.

Fragile X syndrome is the most common inherited cause of intellectual and developmental disability. The influence of environmental variables on behaviors associated with the syndrome has received only scant attention. The current study explored the function served by problem behavior in fragile X syndrome by using experimental functional analysis methodology with 8 children with fragile X.

Discrepancy in functional analysis results across two settings: implications for intervention design.

Functional analyses that were conducted in two settings (playground and classroom) indicated that problem behavior was sensitive to adult attention on the playground and tangible items in the classroom. Attention- and tangible-based interventions were designed based on the results from each of the assessment environments and were compared. The attention-based intervention was more effective on the playground, and the tangible-based intervention was more effective in the classroom.

A tutorial on the concept of the motivating operation and its importance to application.

Motivating operations (MOs) exert a powerful influence over operant relations and hold significant implications for those working in applied settings. In this paper, we describe the concept of the MO and provide "real world" examples. Particular emphasis is given to the concept of the conditioned MO (CMO).

Functional analysis of the early development of self-injurious behavior: incorporating gene-environment interactions.

The analysis of the early development of self-injurious behavior (SIB) has, to date, reflected the wider distinction between nature and nurture. Despite the status of genetic factors as risk markers for the later development of SIB, a model that accounts for their influence on early behavior-environment relations is lacking. In the current paper we argue that the investigation of gene-environment interactions (GxE) and other forms of gene-environment interplay could potentially enhance current approaches to the study of self-injury.

Manipulating the behavior-altering effect of the motivating operation: examination of the influence on challenging behavior during leisure activities.

We examined the behavior-altering effect of the motivating operation on challenging behavior during leisure activities for three individuals with severe disabilities. Prior functional analyses indicated that challenging behavior was maintained by positive reinforcement in the form of attention or tangible items for all participants. During leisure sessions, each participant played preferred games (cards, jigsaws) with two individuals without disabilities.

Incorporating "motivation" into the functional analysis of challenging behavior: on the interactive and integrative potential of the motivating operation.

Sensitivity theory attempts to account for the variability often observed in challenging behavior by recourse to the "aberrant motivation" of people with intellectual and developmental disabilities. In this article, we suggest that a functional analysis based on environmental (challenging environments) and biological (challenging needs) motivating operations provides a more parsimonious and empirically grounded account of challenging behavior than that proposed by sensitivity theory. It is argued that the concept of the motivating operation provides a means of integrating diverse strands of research without the undue inference of mentalistic constructs.
