Question

question 10
baseline of self - injurious behavior is taken in the childs home and at school. treatment for behavior is then introduced in the childs home, and baseline is continued at school. then, treatment is applied in the home and at school. this is a(n) _______ design.
a abab reversal design
b multiple - baseline across behaviors
c abac
d multiple - baseline across situations

Explanation:

The problem involves a behavior (self - injurious behavior) being measured in two situations (home and school), with treatment introduced in one situation (home) first and then in both. A multiple - baseline across situations design applies an intervention across different settings (situations) for the same behavior. Option A (ABAB reversal) involves reversing treatment, which isn't the case here. Option B (multiple - baseline across behaviors) is for different behaviors, not situations. Option C (ABAC) is not a standard behavior - analysis design in this context. So the correct design is multiple - baseline across situations.

Answer:

D. multiple - baseline across situations
