The rates of problem behavior maintained by different reinforcers were evaluated across 3 preference assessment formats (i.e., paired stimulus, multiple-stimulus without replacement, and free operant). The experimenter administered each assessment format 5 times in a random order for 7 children with developmental disabilities whose problem…

Individuals with intellectual and developmental disabilities are often prescribed psychotropic medication to treat behaviors such as aggression and self-injury. Evaluation of these medications is often based on caregiver report or changes in frequency of behavior. The purpose of this research was to characterize the rate and function of problem…

The current study evaluated the use of various behavioral measures of running away with regard to (a) the differential utility of interval- versus event-based measures, (b) the differential utility of rate versus duration measures, (c) the utility of correcting for occurrence opportunity, and (d) the influence of unit of analysis (i.e.,…

Describing the state of the science of ABA, this comprehensive handbook provides detailed information about theory, research, and intervention. The contributors are leading ABA authorities who present current best practices in behavioral assessment and demonstrate evidence-based strategies for supporting positive behaviors and reducing problem…

Seven parents conducted assessments in an outpatient clinic using a prescribed hierarchy of antecedent and consequence treatment components for their children's problem behavior. Brief assessment of potential treatment components identified variables controlling children's appropriate behavior. Experimental control was achieved for six of the…

This commentary summarizes methodological and conceptual issues in functional analysis methodologies and offers some suggestions for their resolution. Considered are increasing complexity, absence of contingencies during assessment, use of subtle manipulations, alternative assessment strategies, analysis of antecedent influences on behavior,…

A behavioral assessment procedure was evaluated with five children with severe/profound mental retardation who exhibited feeding problems of limited intake. Subjects were fed various types of foods. Results indicated each subject fit into one of four categories: (1) total food refusal, (2) food type selectivity, (3) food texture selectivity, or…

Time-based lag sequential analyses were conducted on 23 topographies of challenging behavior shown by 5 young people with severe mental retardation across 2 settings. Potential behavioral functions were identified for 21 of the 23 behaviors. Response classes were identified for four participants. Cross-validation with brief experimental analyses…

Three methods used in applied behavioral analysis research and appropriate for conducting a functional assessment of problem behavior in persons with mental retardation are described. They are informant assessment (e.g., behavioral interviews, rating scales, and questionnaires), direct observation assessment, and experimental analysis. (Author/DB)

A functional analysis of distinct topographies of aberrant behavior displayed by 4 individuals (ages 6-28) with moderate to profound mental retardation indicated that hypotheses of separate functions for distinct behaviors can be generated using both extended and brief functional analyses when results are graphed in the aggregate and separated by…

This commentary on assessing the social validity of behavior-change programs examines which groups should be included in the assessment, whether social validity assessment should be required, and whether new methods are needed. The paper notes that social validation should be an interactive process between researcher and consumer. (JDD)

Incorporating statistical process control (SPC) methods into applied behavior analysis is discussed. It is claimed that SPC methods would likely reduce applied behavior analysts' intimate contacts with problems and would likely yield poor treatment and research decisions. Cases and data presented by Pfadt and Wheeler (1995) are cited as examples.…

Five elementary students with severe emotional disturbance participated in a comprehensive functional assessment process designed to yield a useful understanding of their desirable and undesirable behaviors. Individualized hypotheses were developed regarding relationships between classroom events and the occurrence of target behaviors, and…

This paper reviews functional analysis' historical development as an important pretreatment assessment and analysis strategy for academic and social behavior problems. It examines seminal and influential studies to document historical and contemporary progression, functional analysis' contributions, and future directions. Conclusions focus on…

This paper discusses the practice of social validity assessment in applied behavior analysis, proposes elements that should be included in state-of-the art assessment procedures, offers a taxonomy of consumers to guide the construction and circulation of assessments, and suggests strategies to improve social validity assessment.
