Validity and Reliability of the Research Article

Article: Zarei, E., Ahmadi, F., Sial, M. S., Hwang, J., Thu, P. A., & Usman, S. M. (2019). Prevalence of burnout among primary health care staff and its predictors: a study in Iran. International journal of environmental research and public health16(12), 2249.


Reliability entails the consistency of a method or approach in measuring something. Reliability in quantitative research emphasizes consistency, which focuses on instrumentation or outcome (Heale & Twycross, 2015). This means that the results are consistently achieved using the same method under the same circumstances. The article is reliable since it has used a reliable survey instrument to measure burnout among the primary healthcare staff. The data collection instrument was the Maslach Burnout Inventory, which consisted of three subscales personal achievement, emotional exhaustion, and depersonalization (Zarei et al., 2019). The article shows consistency among the responses in the cross-sectional examination, which has utilized the MBI instrument to measure burnout among the primary healthcare staff.


Validity is the degree to which the scores from the measure are variable as intended (Heale & Twycross, 2015). The purpose of the study was to measure the burnout of healthcare employees. The study was designed to explore burnout, which is accurately measured among the primary healthcare staff (Zarei et al., 2019). This made quantitative research valid. The study has measured burnout with the three main components: depersonalization, emotional exhaustion, and personal achievement. High scores on DP and EE subscales correspond to high burnout, while low scores on the PA subscale are linked to high burnouts. The article is valid since the scores on the subscales have related to the MBI measures have demonstrated the high validity of the research on showing the prevalence of burnout among the primary healthcare staff.

The article has suitably linked to the literature review on burnout among healthcare workers. Ideally, professional burnout has been an unfortunate situation among healthcare workers. The article has documented the prevalence of burnout among healthcare staff. The article has demonstrated systematic investigation, which has been well designed to contribute to the generalizable knowledge of burnout among primary healthcare staff. The cross-sectional examination in this article correlates to the previous studies, which suggest that burnout is a common issue among the primary healthcare staff.
