A replication study involves reproducing an original research study using the same methods but with different subjects and experimenters. Researchers investigate whether similar findings will be obtained in different settings and with different samples. Polit and Beck (2008) define a replication study as a “deliberate repetition of research procedures in a second investigation for the purpose of determining if earlier results can be confirmed” (p. 764). Replication is needed not only to establish the credibility of research findings but also to extend generalizability.
