A content analysis of written behavior management programs.

A method is described for assessing the elements of individual behavior management programs. The content analysis, consisting of 24 items covering the general categories of behavior specification, objectives, program procedures, data collection, and quality assurance, was applied to 141 written behavior programs of two large institutions from different regions of the United States. These data can be utilized readily to establish a data base for program evaluation at both the individual and institutional levels. In addition, to provide a measure of validity, the items included in the content analysis were rated by experts in the treatment of severe behavior disorders. General strengths and weaknesses of the programs, and of the content analysis itself, are discussed in light of their implications for program implementation and evaluation.

Behavior Therapy

Reduction of multiple aberrant behaviors and concurrent development of self-care skills with differential reinforcement.

A modified functional analysis was used to assess the behavioral function of a profoundly retarded man's self-injurious behavior (SIB). Results of that analysis showed that the behavior was most likely to occur in a demand context (self-care instructions) but was maintained by positive reinforcement in the form of attention and physical contact. The results of the functional analysis also prescribed a treatment involving differential reinforcement of alternative behavior (DRA). Further investigation showed that other aberrant behaviors, such as aggression and disruption, were members of the same functional response class as SIB. The differential reinforcement of alternative behavior (DRA) procedure effectively reduced those behaviors while compliance to a self-care acquisition task increased markedly. The results are discussed in terms of the importance of determining behavioral function prior to treatment.

Reliability analysis of the Motivation Assessment Scale: a failure to replicate.

The Motivation Assessment Scale (MAS) has been proposed as an efficient questionnaire for identifying the source of reinforcement for an individual's self-injurious behavior (SIB). A previous reliability analysis of the MAS (Durand & Crimmins, 1988) reported interrater correlation coefficients ranging from .66 to .92, based on a comparison of responses provided by classroom teachers. In this study, the reliability of the MAS was reexamined with two independent groups of developmentally disabled individuals who exhibited SIB (N = 55). For the institutional sample (n = 39), the MAS was given to two staff members (a supervisor and therapy aide) who work with the individual daily. For the school sample (n = 16), the MAS was given to the teacher and teacher's aide who taught the student. The correlational analyses completed by Durand and Crimmins (1988) were repeated; in addition, a more precise analysis of interrater reliability was calculated based on the actual number of scoring agreements between the two raters. Results showed that only 16 of the 55 raters agreed on the category of reinforcement maintaining their client's or student's SIB, that only 15% of the correlation coefficients obtained were above .80, and that none of the reliability scores based on percent agreement between raters was above 80%.

An analysis of error-correction procedures during discrimination training.

Mechanisms involved in error-correction procedures during behavioral acquisition were examined. Seven developmentally delayed subjects participated in match-to-sample discrimination training, consisting of three conditions arranged in a multielement design. Correct responses in all conditions were followed by praise and either food or pennies. In the baseline condition (differential reinforcement), an error produced no consequences. In the practice condition, an error was followed by repetition of the trial until a correct response occurred. In the avoidance condition, an error was followed by additional trials consisting of irrelevant stimuli; this condition separated the effects of repeated exposure to the same task from those of negative reinforcement, both of which existed in the practice condition. All 7 subjects made noticeable progress in the baseline condition. However, 5 of the 7 performed better in one of the error-correction conditions: 2 performed better in the practice condition, and 3 performed better in the avoidance condition. These data indicate that error-correction procedures may serve multiple functions and suggest that the practice requirement in this study included both avoidance and stimulus control components. More generally, the data indicate that additional control procedures should be included in acquisition studies to identify the relevant behavioral mechanism(s).
