Quantitative Article Critique This study consisted of quantitative research because it used precise measurements to obtain data that were statistically analyzed. The purpose of the study, Model of functional performance in obese elderly people with chronic obstructive pulmonary disease by Dr. Jochebed Bosede Ade-Oshifogun (2012), was to test the relationships among percent truncal obesity; disease severity; dyspnea; functional capacity; and functional performance of elderly people with chronic obstructive pulmonary disease (COPD). The research is significant and relevant to nursing because COPD is the fourth-leading cause of chronic morbidity and mortality in the United …show more content…
Reliability coefficients were calculated for all variables in the path model, and they met or exceeded minimal levels (Ade-Oshifogun, 2012). All research information was scrutinized for any missing data. All data were subjected to univariate analysis of variance (Ade-Oshifogun, 2012). Path analysis with multiple linear regressions was utilized to test the relationships among the study variables (Ade-Oshifogun, 2012). The techniques utilized were appropriate for this study as they accurately verified that the data were valid and …show more content…
This allowed for more thorough and precise measurements of all the involved factors. Another strength was that this was possibly “the first study to incorporate body composition as a variable into a functional performance model” (Ade-Oshifogun, 2012, p.238). A major limitation was that the severely and morbidly obese were not included in the study due to the weight limit of the DEXA scanner (Ade-Oshifogun, 2012).. This caused two major groups to be excluded and no pertinent data was obtained. Another limitation was that the study group was English-speaking only, which did not allow for potential regional differences (Ade-Oshifogun,
