Intervention groups, sometimes referred to as treatment groups, receive some form of intervention, such as a new reading program, designed to result in some change in behavior. Control or comparison groups do not receive the intervention.
There are two main types of trials or studies - interventional and observational. Interventional trials aim to find out more about a particular intervention, or treatment. Observational studies aim to find out what happens to people in different situations.
(kun-TROLD KLIH-nih-kul TRY-ul) A clinical study that includes a comparison (control) group. The comparison group receives a placebo, another treatment, or no treatment at all.
Community trials are an extension of field trials. In community trials the study group is the entire community, rather than individuals. Conceptually, the difference is whether or not the intervention is implemented separately for each individual.
As mentioned in our publication Types of Clinical Trial Design, one of the designs is based, on the inclusion or not, of a control group to compare the effects of the investigational treatment. Trials that do not include it are called uncontrolled trials and those that do are called controlled trials.
Interventional studies can be divided broadly into two main types: (i) “controlled clinical trials” (or simply “clinical trials” or “trials”), in which individuals are assigned to one of two or more competing interventions, and (ii) “community trials” (or field trials), in which entire groups, e.g., villages, ...
Definition. Community intervention trials are research studies designed to evaluate the effects of public health interventions on a community-wide basis, rather than on individuals.
Community-based research offers a notable advantage to smaller, independent practices primarily due to one factor: patients do not have to travel far to participate in a clinical trial, which can boost enrollment and advance scientific knowledge.
Non-Clinical Trial Research is a subcategory of regulated human research. Non-Clinical Trial Research also known as “non-interventional” or “observational” research because the study plan does not involve an intervention controlled by the researcher.
