2020年9月9日 · A pretest-posttest design is an experiment in which measurements are taken on individuals both before and after they’re involved in some treatment. Pretest-posttest designs can be used in both experimental and quasi-experimental research …

2019年11月26日 · Pre-test and post-test research is one of many forms of quasi-experimental design. The term “quasi” means resembling experimental research, but does not imply that the quasi-experimental method is true experimental research.

Pretest-posttest designs are an expansion of the posttest only design with nonequivalent groups, one of the simplest methods of testing the effectiveness of an intervention. In this design, which uses two groups, one group is given the treatment and the results are gathered at the end.

The basic premise behind the pretest–posttest design involves obtaining a pretest measure of the outcome of interest prior to administering some treatment, followed by a posttest on the same measure after treatment occurs.

In this article, we showed how second order multiple group latent curve modeling (SO-MG-LCM) could represent a useful methodological tool to have a more realistic and informative assessment of intervention programs with two waves of data.

A pretest–posttest design is a form of pre-experimental design that does not have control or comparison groups. This is a major difference between pretest–posttest designs and processes such as quasi-experimental designs and randomized controlled trials.
