Critically Appraising Quantitative Studies Research Paper

Critically Appraising Quantitative Studies - Research Paper Example are true for the people in the study while external validity is the reflection to the target population by the study for people who are not included in the study. Biases that may lead to internal invalidity include statistical analysis, withdrawals and dropouts, blinding, data collection methods, allocation bias, confounding, intervention integrity. Internal validity occurs in unbiased results and only internally viable research can be generalized ensuring external validity. Reliability denotes the amount of trust that can be given to a research and is therefore a measure of the likelihood for reproducing the same research (LoBiondo-Wood & Haber, 2010). This is determined using statistical techniques relating to frequency of occurrence of chance and uncertainty of an observation. The threshold for chance use to check for reliability is 5% where a research phenomenon is reliable if it occurred more than 5% and its occurrence is therefore not by chance. Applicability is the extent to which the results obtained can have an impact on practice where contrast is made against statistical significance. This entails checking if the research will generate any difference on the users of the research. The most important factor is validity because applicability is dependent on reliability and validity but results can be reliable but not valid making them unable to be generally applied. It is also more important because reliability is a necessary condition for validity however it is not a sufficient condition. In conclusion, it is more important where the research outcome is both reliable and valid for the best research

EBP - Assignment Example This paper presents a table of evidence drawn from EBP studies. For each journal article reviewed, it is summarized under the headings shown in the table below. For decades, psychiatrists have used psycho-dynamically-driven interventions to deal with a variety of mental disorders in children and adolescents. However, there had been no meta-analyses to evaluate how effective these therapies are, hence the need for the study (Abbass, Rabung, & Midgley, 2013). The study involved 186 cancer patients and 117 of their partners at the Oncology and Hematology clinic of a University hospital. ANOVAs were used to analyze temporal change and group effects among people with POI and those without. For patients with high levels of distress, it was difficult to conclude of the effectiveness of POI as these patients received additional POI. For moderately stressed patients, POI, as effected in Switzerland, do not improve the well-being of those patients. The study concluded that there was the need for further studies involving more intense POI interventions (Barth, Delfino, &Kunzler, 2013) The study set out to establish whether or not cancer patients showed improvement in their goal adjustment capabilities while receiving psychosocial care(Zhu, Ranchor, Lee, Garssen, &Sanderman, 2015). It further sought to establish whether there was a relationship between those increases and changes in the symptoms of fatigue, anxiety and depression. The study involved 241 cancer patients under psychosocial care at a psycho-oncology facility in the Netherlands. The researchers collected data before the start of the psychosocial care and nine months later. The researchers then used hierarchical regression analysis to analyze the data. Scholars have studied the effectiveness of the International Child Development Programme (ICDP) for the general population in the short-run. This
