Validityand Reliability Scale

Peer-reviewis a valid research method because it uses empirical data.Professionals in a given field introduce unique form of regulationsince they are using their knowledge to determine the accuracy of theoriginal work. For example, Yeşilbalkan et al. (2008) used aten-person team to translate the research tool from English toTurkish. Researchers then used an export tool to translate theinformation from Turkish to English. Both the tool and humantranslated versions were given to cancer specialists to determine thevalidity of the human and tool translated versions when compared tothe original versions (Yeşilbalkan, 2008).

Peer-reviewedcontent’s reliability is high since specialists use theirexperience to identify possible flaws in the study outcome. Forinstance, at the third stage of the study, a ten-person professionalteam tested reliability of the cancer tool. The team was using thetool version that professionals had improved during the second phaseto test its reliability in assisting cancer patients. They ensured tofix discrepancies that they could hinder the tool’s efficiency suchas unclear statements. The importance of conducting the correctionwas to ensure that the final piece was easy to understand and free oferrors. If the various teams of experts had not improved the toolprior to recommending cancer patients to use it, it would have beenchallenging for targeted persons to achieve intended benefits(Yeşilbalkan, 2008).

Peer-reviewsenhances reliability of the study because as groups of professionalsin the field analyze its content to determine whether the final pieceis compliant with the set rules and regulations. If a study hasempirical data, peer-reviewers conduct practical tests. For example,the cancer experts reviewing the translated tool modified inaccuratesentences that could hinder efficiency of the tool (Yeşilbalkan,2008). They also distributed the tool to targeted cancer patients toensure they can meet intended environment.
