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.
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 ...
These are generally treatments based on applied behavior analysis (ABA) and involve intensive training of the therapists, extensive time spent in ABA therapy (20–40 hours per week) and weekly supervision by experienced clinical supervisors—known as board certified behavior analysts. [45]
Clinical behavior analysis (CBA; also called clinical behaviour analysis or third-generation behavior therapy) is the clinical application of behavior analysis (ABA). [1] CBA represents a movement in behavior therapy away from methodological behaviorism and back toward radical behaviorism and the use of functional analytic models of verbal behavior—particularly, relational frame theory (RFT).
Ex post facto recruitment methods are not considered true experiments, due to the limits of experimental control or randomized control that the experimenter has over the trait. This is because a control group may necessarily be selected from a discrete separate population. This research design is thus considered a quasi-experimental design.
Critical appraisal (or quality assessment) in evidence based medicine, is the use of explicit, transparent methods to assess the data in published research, applying the rules of evidence to factors such as internal validity, adherence to reporting standards, conclusions, generalizability and risk-of-bias.
The Solomon four-group design is a research method developed by Richard Solomon in 1949. [1] It is sometimes used in social science , psychology and medicine. It can be used if there are concerns that the treatment might be sensitized by the pre-test . [ 2 ]
One behavioral activation approach to depression had participants create a hierarchy of reinforcing activities, rank-ordered by difficulty. Participants then tracked goals along with clinicians who used a token economy to reinforce success in moving through the hierarchy of activities, being measured before and after by the Beck Depression Inventory.
