Matheson,Bruce and Beauchamp (1970, p34) use the term "one shot case study"
to refer to a one _group_ design where a treatment is introduced and a
measure taken after the treatment. As they say, "Data comparison is a
crucial aspect of the research process; consequently, the one shot case
study is not a legitimate research design, because it does not permit
comparison."
They then proceed to talk about one group before-after designs, which are
somewhat better.
Again, these are group designs, not single subject designs.
A quick look shows no mention of single subject designs in the contents or
index (I don't have time to read the whole book).
The 1978 edition does have a chapter on single subject experimental
designs. In introducing the basic A-B design, they say that "it represents
an improvement over uncontrolled one-shot case studies." They proceed to a
reasonable looking discussion of more elaborated single subject designs.
I don't have any later editions available.
