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.
Answer the following four questions to determine if your study is a clinical trial: Does the study involve human participants? Are the participants prospectively assigned to an intervention? Is the study designed to evaluate the effect of the intervention on the participants?
(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.
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.
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.
In summary, the primary distinction lies in the focus on human subjects and the testing of interventions in clinical trial research, whereas non-clinical trial research encompasses a broader spectrum of studies that may not involve direct interventions on human participants.
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.
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, ...
Clinical research helps find new and better ways to detect, diagnose, treat, and prevent disease. Types of clinical research include clinical trials, which test new treatments for a disease, and natural history studies, which collect health information to understand how a disease develops and progresses over time.
The main difference is clinical trial participants are assigned to get an intervention, but observational study participants are not assigned to get an intervention.
