Behavioral diagnostics.
The contemporary behavior analyst, to operate ethically and effectively, must be aware of many more factors affecting behavior than simple consequences. Although the literature demonstrating the effectiveness of active behavior management is impressive, a compelling argument can be made that a great number of behavior problem seen in individuals with developmental disabilities may be attributable to factors other than consequences. Our experience has been more often than not that physiological, organic, medication, or situational variables are the actual culprits in maladaptive behavior. Individuals with severe or profound retardation may respond to aversive features of their environment by displaying noncompliance, tantrums, aggression, or self-injurious behavior. These antecedents can affect their behavior just as powerfully as can the consequences of their behavior. Behavior analysts must become sensitive to these potential factors and be prepared to employ behavioral diagnostic strategies in the search for the causes of maladaptive behavior. Finally, they must be prepared to design rather unconventional passive behavior management treatment programs involving the manipulation of the antecedent environment. In the case of Carrie, from the example at the beginning of this paper, the analysis yielded the hypothesis that her face scratching was a reaction to sinus blockage caused by seasonal allergies. Her treatment involved daily dosages of antihistamines administered by our nurses and subsequent elimination of the scratching. Tom was found to be suffering from "wheelchair fatigue." When he was allowed to recline on other surfaces (e.g., bean bag chair, mat, bolster) on a regular basis, he did not attempt any form of self-injury. Melissa was found to have a severe case of Pre Menstrual Syndrome as well as seizure disorder, and was treated with the appropriate medications. Her headbanging was reduced to a few minor incidents per month. Walter's tantrums on closer inspection seemed part of a chain of behavior leading to seizure-like attacks. Preliminary evidence suggests that when he is treated with phenobarbital the tantrums and aggression disappear. And finally, Debbie was found to be very sensitive to a variety of discomforting events. She would cry, sob, and scream when she was wet, thirsty, hungry, and tired. Changing her regularly, offering her water every hour and extra snacks in the morning as well as short naps in the early afternoon eliminated the crying and sobbing. She now participates with the other clients and seems to enjoy the house activities.(ABSTRACT TRUNCATED AT 400 WORDS)
