Functional analyses and treatment of precursor behavior

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.     

Identification of environmental determinants of behavior disorders through functional analysis of precursor behaviors

Experimental analysis procedures have been shown to be effective means for identifying the environmental determinants of problem behaviors. A potential limitation of these procedures is that it is necessary to produce and document patterns in the occurrence of the problem behavior during the assessment. In the case of severe behavior disorders, this may place the participant or therapist at such risk as to preclude the analysis. The current study arranged experimental analysis contingencies for precursor behaviors that had been observed to reliably precede the occurrence of problem behaviors targeted for reduction. For each of the 4 participants, it was possible to infer the maintaining variables for problem behaviors based on the outcomes of precursor analysis. These results suggest that the current procedures represent a promising alternative method for reducing risk during functional analysis of problem behaviors.     

Preliminary investigation of two functional assessment methods for people with dementia: Effectiveness and acceptability

Many functional assessment procedures have been developed and validated for use with people with intellectual and developmental disabilities. However, there is a paucity of research exploring the utility and social acceptability of functional assessment methods for people with dementia. We conducted direct observations in the natural environment to produce data for conditional probability analyses and an experimental functional analysis of the behavior of two women with dementia. We found that the conditional probability analysis yielded similar conclusions about function as the data from the experimental functional analysis for both participants. Importantly, staff rated the direct observations as more socially acceptable. We also report barriers to conducting both methods in older adult settings that warrant further exploration, including the use of the assessments with people with dementia and intact vocal verbal repertoires.     

Precursor behavior and functional analysis: A brief review

Researchers have developed precursor functional analyses to provide an alternative, and presumably safer, format for functional analysis of severe problem behavior. When researchers use functional analysis contingencies for precursor behaviors, it is possible to infer functional characteristics about severe problem behaviors based on patterns of less severe precursor behaviors, permitting practitioners to complete the assessment with less risk to clients, practitioners, or others. The current paper discusses recent advances in the development and validation of precursor identification, and offers suggestions and future directions for investigating and implementing precursor functional analyses. We propose a decision‐making model, in which practitioners integrate procedures to identify precursors into the functional‐analysis process, to expedite the analysis of severe problem behaviors.     

ASSESSING THE UTILITY OF A DEMAND ASSESSMENT FOR FUNCTIONAL ANALYSIS

We evaluated the utility of an assessment for identifying tasks for the functional analysis demand condition with 4 individuals who had been diagnosed with autism. During the demand assessment, a therapist presented a variety of tasks, and observers measured problem behavior and compliance to identify demands associated with low levels of compliance or high levels of problem behavior (low‐probability demands) and demands associated with high levels of compliance or low levels of problem behavior (high‐probability demands). Results showed that clearer functional analysis outcomes were obtained for 3 of the 4 participants when low‐probability rather than high‐probability demands were used.     

Impact of Language on Behavior Assessment Outcomes

Conducting a functional analysis is the “gold standard” of behavior assessment with best practices recommending identification of idiosyncratic variables as essential to valid results. One potential variable that might impact assessment results is language of assessment. For individuals who operate in environments with multiple languages (e.g., English and Spanish), the language of assessment might differentially impact assessment results. Therefore, there is a need to evaluate if language of assessment affects identified function. The current study presents the results of 10 cases in which the experimenters conducted assessments (i.e., functional analysis) in both the Spanish and English language. Participants were nine children with autism who engaged in problem behavior and whose parents reported Spanish as the primary home language. Result indicates correspondence of function for eight of the ten cases. Discussion of results and recommendations for practice and future research are presented.
