Question of the Day
While reviewing treatment documentation, Marcus, a speech-language pathologist working in a pediatric outpatient clinic, is considering using a single-subject design (SSD) to monitor a client’s progress with a new phonological therapy. He is familiar with the general structure of SSDs and their ability to track individual progress over time. As he reflects on the terminology used in SSDs, he encounters the following question in his review materials:
Which of the following statements is not true about single-subject designs?
The A phase is the treatment phase.
They are useful in establishing treatment efficacy.
The multiple-baseline design avoids the disadvantage of treatment withdrawal.
A disadvantage of single-subject designs is that they cannot efficiently predict the behavior of groups of individuals.
