To implement an experimental pretest-posttest design, it is necessary to have the ability to collect pretest data (B) to establish a baseline for comparison and random assignment of participants to treatment and control groups (E) to reduce bias and increase the generalizability of the results. Inclusion of a second control group (A) or using two posttreatment data collection times (C) are not necessary components of this design. Participants randomized to the control group only (D) would not allow for comparison between treatment and control groups.
