Unformatted Sample Text from the Research Paper:
In a 1993 article in the "Journal of Consulting and Clinical Psychology" titled "Single-Case Methodology in Psychotherapy Process and Outcome Research" author Russell B. Hilliard attempts  to delineate and explain single-case research methodology as it is used in psychotherapy research. The author subclassifies single-case research into 1. single-case experiments, 2. single-case quantitative analyses,  and 3. case studies. He attempts to demonstrate that single-case research, despite its sometime negative associations, does have significant value in psychotherapy research. Hilliard notes that even  authors that have previously discounted single-case studies as having no place in psychotherapeutic research have now reversed their stance on the issue. Hilliard demonstrates that that reversal in opinion  is warranted, that single-case studies must simply be viewed in a different light than research involving larger sample sizes and contends that single-case studies are better viewed as a:  "subclass of intrasubject research in which aggregation across cases is avoided and the generality of ones  findings is addressed through replication on a case-by-case basis" (373) Hilliard further clarifies that intrasubject  research is distinguished from intersubject research. In the first type of research the research variable is found within the subject themselves and measurements of that variable are repeated over  time to assess its variation. In intersubject research, in comparison, the variable differs "between or across subjects". Hilliard describes the latter as requiring a cross-sectional perspective as opposed  to the longitudinal perspective required for intrasubject variation. He points out that: "not all
