An Evidence Supported Treatment (EST) is a treatment or intervention protocol that has scientific, empirical research evidence for its efficacy with its intended problems and populations.
The evidence supporting a treatment may be based on a variety of research designs.
- Randomized Clinical Trial (RCT)
- Controlled studies without randomization
- Open trials, pre-post-, or uncontrolled studies
- Multiple baseline, single case designs
The degree to which we have confidence in the effectiveness of a treatment varies by the quality of empirical support it has. Factors to consider when evaluating the evidence supporting a particular treatment include:
- Have Systematic Reviews of multiple studies found positive results?
- The number of RCT's conducted that have found positive results.
- Have RCT's found negative results?
- Have researchers other than the developers of the treatment conducted RCTs and found positive results?
- Other supporting research designs
- Has research found positive results with different populations of clients?
- Research methods used such as sampling approaches, sample sizes, varied client populations, comparison treatments, measurement approaches, effect sizes, problems affected.
