A clinical control group can be a placebo arm or it can involve an old method used to address a clinical outcome when testing a new idea. For example in a study released by the British Medical Journal, in 1995 studying the effects of strict blood pressure control versus more relaxed blood pressure control in diabetic patients, the clinical control group was the diabetic patients that did not ...
Random assignment or random placement is an experimental technique for assigning human participants or animal subjects to different groups in an experiment (e.g., a treatment group versus a control group) using randomization, such as by a chance procedure (e.g., flipping a coin) or a random number generator. [1]
In the design of experiments, a between-group design is an experiment that has two or more groups of subjects each being tested by a different testing factor simultaneously. This design is usually used in place of, or in some cases in conjunction with, the within-subject design , which applies the same variations of conditions to each subject ...
Experiment, often with separate treatment and control groups (see scientific control and design of experiments). See Experimental psychology for many details. Field experiment; Focus group; Interview, can be structured or unstructured. Meta-analysis; Neuroimaging and other psychophysiological methods
Randomization helps distribute the effects of nuisance variables evenly across treatment groups. By using one of these methods to account for nuisance variables, researchers can enhance the internal validity of their experiments, ensuring that the effects observed are more likely attributable to the manipulated variables rather than extraneous ...
Multimodal therapy (MMT) is an approach to psychotherapy devised by psychologist Arnold Lazarus, who originated the term behavior therapy in psychotherapy. It is based on the idea that humans are biological beings that think, feel, act, sense, imagine, and interact—and that psychological treatment should address each of these modalities.
An example might be a drug with many adverse effects given first, making patients taking a second, less harmful medicine, more sensitive to any adverse effect. Second is the issue of "carry-over" between treatments, which confounds the estimates of the treatment effects. In practice, "carry-over" effects can be avoided with a sufficiently long ...
