Evidence-Based Program (EBP)

Good Essays

As a beginning point in the selection of an evidence-based program (EBP), it is crucial to distinguish the extent of the EBP. This process has four (4) elements: 1) intended population; 2) intervention target; 3) baseline severity level; and 4) intervention delivery characteristics (Durlak & DuPre, 2008). 1) Intended population: For whom is the intervention intended? Intended population alludes to what individuals will be provided intervention. EBPs commonly determine certain population attributes for whom they are expected and/or with whom they have been tested. These attributes incorporate traits, for example, developmental level (age range or grade range), sex, race/ethnicity, and dialect. Along these lines, it is critical to …show more content…

Intervention delivery characteristics include the interventionist, format, frequency, and time. Typically, EBPs specify these characteristics based on how the EBPs were tested or how they were intended to be delivered. The interventionist is the person who will deliver the EBP. There are numerous options from which to chose, reflecting a variety of professional roles. Format refers to the audience who will receive the intervention from the interventionist. Frequency refers to how often the intervention will be delivered, and ranges from multiple times per day to one time only. Finally, time refers to how long the intervention delivery requires each instance the intervention is used. In some cases, the intervention delivery might be brief or it might be a few hours or even days (Durlak & DuPre, …show more content…

A rigorous evaluation typically involves either an experimental design (like that used in randomized controlled trials) or a quasi-experimental design. In an experimental design, people are randomly assigned to either a treatment group, which participants in the program, or the control group, which does not. After the program is completed, the outcomes of these two (2) groups are compared. This type of research design helps ensure that any observed differences in outcomes between the two (2) groups are the result of the program and not other factors. Given that randomization is not always possible, a quasi-experimental design is sometimes used. In evaluations using this design, the program participants are compared to a group of people similar in many ways to the program participants. However, because a quasi-experimental design does not randomly assign participants to program and non-program groups, it is not as strong a design as the experimental approach. Because there may be unobserved differences between the two (2) groups of people who are being compared, this design does not allow program evaluators to conclude with the same certainty that the program itself was responsible for the impacts observed. Therefore, it would be conducive to try and conduct an experimental design if at all possible (Cooney, Huser, Small, & O’Connor,
