Bk. Martens et al., Identifying effective treatments from a brief experimental analysis: Usingsingle-case design elements to aid decision making, SCH PSYCH Q, 14(2), 1999, pp. 163-181
Experimental analysis refers to the manipulation of an independent variable
while observing its effects on behavior. In the 1980s, researchers began c
onducting brief experimental analyses to identify the variables maintaining
severe problem behavior in individuals with developmental disabilities. By
adapting certain design elements, brief experimental analyses have been us
ed in school and clinical settings to compare quickly two or more treatment
alternatives, allowing one to select the most effective option. This paper
discusses the benefits of using brief experimental analyses to aid in trea
tment selection, identifies the forms of treatment that are most appropriat
e for this type of analysis, and describes key design elements (i.e., abrid
ged data series, alternating and sequential treatment applications, and min
i-withdrawals) for comparing two or more treatments efficiently. A study is
presented demonstrating the use of these design elements to identify an ef
fective intervention for two preschool students. The article discusses the
implications of these strategies and presents resources for further study.
