QUANTITATIVE RIGOR 1
The study does notfit the definition of an experimental study because it is anintervention towards increasing teamwork among nurses. The studycould be turned into an experimental design by testing the impactover the train-the-trainer intervention. I would propose aquasi-experimental design, and pre- and posttest.
Interventionfidelity was covered through increasing nursing teamwork anddecreasing missed nursing care (Kalisch, 2013). I would strengthevidence of intervention fidelity though continued programs usingsimulation exercises, instructional topic sections, and groupbriefings over building trust.
Incomplete trialreporting was a threat to internal validity. My overall conclusionabout internal validity of this study is that the bias associatedwith the characteristics may result in intervention effectexaggeration.
The context of thestudy (participants and setting) to judge the external validity wasadequately described. Participants and setting was not meant for thegeneralized population since the study only targets the efficacy ofthe nurses intervention following the measure taken based on therole-playing of the participants from a team-oriented leadership.
Construct validityis defined as the degree to which all inferences can be madelegitimately from all the operationalization of a study based on thetheoretical constructs. The authors, (Kalisch, Xie & Ronis),enhanced construct validity by offering potential sustainability onthe ongoing units towards the trainers on internal mentors (Kalisch,2013). Threats include preoperational explication of the constructsand mono-method bias.
Statistical controlof threats to validity includes designing educational program, propertesting to the painkillers’ effectiveness.
To increase thisstudy rigor, one specific strategy could be a clear awareness to abroad range of methodology techniques, which is aimed at identifyingtools that can maximize chances of finding full phenomenon range.
The study’sdesign using the RE-AIM framework components are evaluated through
Intervention speed of the nurses towards becoming internal mentors and opinion leaders within their group’s formal training (Kalisch, 2013).
Again, it is through role-playing scenarios based on challenges with the team.
One of the measures used in the study is the CRM trainingcustomization its validity and reliability revolve around itscontent and format. Their validity follows group debriefing andsimulation exercises (Kalisch, 2013). The measures are reliable inthat it only requires involvement by few members of the team, whichis cost effective and does not require trainers from outside.
In conclusion, study’s rigor and balances of validity types isessential in quality and safety care. Validity types and study’srigor enhances train-the-trainer intervention that shows feasibilityand promise towards efficient and effective approach towards decreasecare setting.
