10.1 Overview of Single-Subject Research
(This is why single-subject research designs are sometimes called small-n designs, where n is the statistical symbol for the sample size.) Single-subject research can be contrasted with group research, which typically involves studying large numbers of participants and examining their behavior primarily in terms of group means, standard ...
Single-Subject Research Designs
Reversal Designs. The most basic single-subject research design is the reversal design, also called the ABA design. During the first phase, A, a baseline is established for the dependent variable. This is the level of responding before any treatment is introduced, and therefore the baseline phase is a kind of control condition.
Single Subject Research
Single subject research designs are "weak when it comes to external validity….Studies involving single-subject designs that show a particular treatment to be effective in changing behavior must rely on replication-across individuals rather than groups-if such results are be found worthy of generalization" (Fraenkel & Wallen, 2006, p ...
Single Subject Research Design
Single subject research design is a type of research methodology characterized by repeated assessment of a particular phenomenon (often a behavior) over time and is generally used to evaluate interventions . Repeated measurement across time differentiates single subject research design from case studies and group designs, as it facilitates the ...

Single-Subject Experimental Design: An Overview
Single-subject experimental designs - also referred to as within-subject or single case experimental designs - are among the most prevalent designs used in CSD treatment research. These designs provide a framework for a quantitative, scientifically rigorous approach where each participant provides his or her own experimental control.

Single-Subject Experimental Design for Evidence-Based Practice
Single-subject experimental designs (SSEDs) represent an important tool in the development and implementation of evidence-based practice in communication sciences and disorders. The purpose of this article is to review the strategies and tactics of SSEDs and their application in speech-language pathology research.
Single-subject design
In design of experiments, single-subject curriculum or single-case research design is a research design most often used in applied fields of psychology, education, and human behaviour in which the subject serves as his/her own control, rather than using another individual/group. Researchers use single-subject design because these designs are sensitive to individual organism differences vs ...
Single-Subject Research Design
Single-subject research, at times referred to as single-case research, is a quantitative approach to examine functional relationships between baseline and experimental conditions over time within individual subjects. The central features of single-subject research include collecting repeated measures of behavior through direct observation ...

This is the level of responding before any treatment is introduced, and therefore the baseline phase is a kind of control condition.
Single-subject research
The reversal design is the most powerful of the single-subject research designs showing a strong reversal from baseline ("A") to treatment ("B") and back again. If the variable returns to baseline measure without a treatment then resumes its effects when reapplied, the researcher can have greater confidence in the efficacy of that treatment. ...
PDF SINGLE SUBJECT RESEARCH What Are Single-Subject/System Designs?
What Are Single-Subject/System Designs? Single-subject designs involve in-depth quantitative study of the response of an individual or. group of individuals to an intervention or the withdrawal of that intervention (Szymanski, 1993). Basically, single-subject designs, focus on a single individual in a research sample (Alberto & Troutman, 1990 ...
15.1 The basics of single-system research design
Single-systems research design, sometimes called single-subject or single-case research design, is distinct from other research methodologies in that, as its name indicates, only one person, group, policy, etc. (i.e., system) is being studied. Because clinical social work often involves one-on-one practice, single-subjects designs are often ...
Single Subject Research Designs
Single-subject design research uses a rigorous, experimental research methodology to identify functional or causal relationships between variables, also making it a useful methodology to define basic principles of behavior and establish evidence-based practices (Horner et al., 2005).
PDF Chapter 1 Overview of the Single Subject Design
An A-B single subject research design encompasses two investigated con-ditions, in which the first condition (A) is a baseline or control condition, and the second condition (B) is an intervention condition. Figure 1.1 and this design descrip-tion can be found in Janosky [8]. In this single subject study, the research question of
Single Subject Designs: Current Methodologies and Future Directions
Knowledge of the best uses, limitations, and quality criteria for single subject design (SSD) research has grown over the decades. High-quality SSDs provide replicable results and advance knowledge. Using modern technology, meta-analysis and systematic review methods can be applied to synthesize results of SSDs to provide best evidence on ...
PDF Single Subject Design-JohnWasson
Single Subject Research Designs (also referred to as single-case experimental designs) are designs that can be applied when the sample size is one or when a number of individuals are considered as one group. These designs are typically used to study the behavioral change an individual exhibits as a result of some treatment.
10.1 Overview of Single-Subject Research
Key Takeaways. Single-subject research—which involves testing a small number of participants and focusing intensively on the behavior of each individual—is an important alternative to group research in psychology. Single-subject studies must be distinguished from qualitative research on a single person or small number of individuals.
