1.1 Field trials are real-life experiments which test directly whether proposed interventions actually work. This makes them powerful tools for gathering evidence for making policy. But, as with all research methods, they come with costs, such as time and resource.
Community trials address the efficacy of preventive interventions applied at the group level (e.g., a social marketing campaign trial). Field trials address preventive interventions applied to individuals (e.g., a vaccine trial).
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.
3.0 COMMUNITY TRIALS: STRENGTHS AND WEAKNESSES It however suffers from 2 main weaknesses: selection bias and controls getting the intervention. Selection bias is likely to occur when allocation is by community.
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.
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.
The methodology of field trial studies is very similar to clinical trials. The difference is that field trials are conducted on healthy individuals and aim to prevent and also the sample size required to this type of study is relatively more, and these studies are usually time consuming and costly.
