Research Analysis - Assignment Example This paper examines two health researches to point out that researches though, similar in type of industry being studied upon, does not always mean that the studies will utilize similar research methods and that appropriate methods should be a huge consideration to be able to study in depth the external and internal validities of such studies. Keywords: analyze, methodologies, research design, variables, interventions, timeframes, rationale, external and internal validity Research Analysis: A Closer Look at the Methodology of Two Different Health Research Studies Research studies were conducted to determine the cause and effect relationship of each independent variable to its corresponding dependent variables. The aim of these studies is to generate conclusions on the relevance of a certain variable to the samples and to provide evidenced based decision making on the issue at hand (â€Å"Study Design†, n.d.). To further analyze the similarities and differences of the methodolo gies used in the two different health research studies, this paper will look at the research designs, variables, interventions, and timeframes and timing along with its corresponding rationales in methods section of each article as used by the authors. ... ata and clinical data of patients, SCHFI scale a 22-item questionnaire that measures heart failure self-care and MLHF questionnaire that is developed to evaluate the quality of life specifically for heart failure patients. Alpha coefficients used for the study are 0.76 for heart failure self-care and 0.94 for quality of life. Data collection was done by soliciting the approval of the physician and the patients to avoid future ethical problems and the interview process thereafter. Data analysis used was descriptive statistics using SPSS base 16.0 software and considering frequencies, means and reliability estimates as well as bivariate correlations as measurements. The purpose of the study is to determine if there are any statistically significant relationships between heart failure, self-care deficits and quality of life among recently hospitalized heart failure patients. The above study showed that there was a clear link between the research purpose which was to determine if there w ere any statistically significant relationships between self-care and quality of life among recently hospitalized heart failure patients and the study design used which was non- experimental such that the study does not involve a control group but refers only to the cross-section sample of the population (â€Å"Evaluation Design†, n.d.). The link can also be inferred by the use of interview process to obtain the data and by the method of analysis which was through the use of descriptive statistics and the social statistics software (SPSS). The intervention in the study was provided for by the inclusion and exclusion criterion that was well defined in the methodology section. The rationale for the inclusion and exclusion criteria to be well defined in the study is to provide the limitation to
