Download file to see previous pages The Levitt study provides a qualitative and a more specific and in-depth evaluation of psychotherapy outcomes for mental health patients. As is common in qualitative studies, they cover a smaller population and results are presented in terms of common themes expressed by respondents (Marshall, 1996). The smaller number of respondents covered for qualitative studies make their results less reliable and less generalizable to a larger population (Daymon and Holloway, 2010). The issue of generalizability is less apparent in quantitative studies, as in the Cottone study which covers a larger number of respondents. The specificity of the results for quantitative studies is however less practical in the actual research, as they provide general figures and numerical equivalents for the results (Scherer-Rath, 2004). The data collection methods for both studies were also different. The Levitt study applied a semi-structured questionnaire in order to gather data from respondents. This method of gathering data is typical of qualitative methods which allow for a more intimate contact between researchers and respondents (Wengraf, 2001). The data was gathered via a one-on-one interview method where the researcher posed the essential questions, and the respondent was not restricted in his answers by a set of choices. This made the data gathering process more detailed and more patient-focused (Flick, von Kardorff, and Steinke, 2004). Due to the smaller population covered, carrying out a more intimate and focused data gathering process was possible. This type of data gathering was however difficult to carry out in the Cottone study and usually in most qualitative studies (Cottrell and McKenzie, 2011). The population is too large to specifically cover within the time allocated for research. Moreover, results had to be translated to numerical figures and using the prescribed scales to measure client progress was the more effective tool for the quantitative study (Thomas, 2009). Using these scales allowed the data gathered to be collated into numerical representations which could be generalized over a bigger population (Horn, 2008). The themes chosen by the researchers in the Levitt study had a good fit to the data gathered. The researchers were able to illustrate how the themes were drawn from the answers. The themes covered specific answers which ultimately helped answer the question being raised by the study. In the Cottone study, the depression and mood disorders scales were used to evaluate the patient outcomes and response to therapy. The scale allowed a measure of patient progress in terms of their specific disorder. It also concentrated on gender differences between respondents in relation to the outcomes from their therapy. Gender measures were however difficult to apply in the empirical sense because the numbers of respondents were lopsided with more females than males in the sample population. Admittedly, with a larger recruited population, a more objective result would have been possible (Evans, 2007). The researchers were also reflexive during the entire process of research in both the quantitative and qualitative studies (Morrow, Boaz, and Brearley, 2012). They identified the ethical considerations they needed to safeguard; they also considered the limitations of the methods they were applying and the results they unveiled after the research. Levitt identified how the number of respondents ...Download file to see next pages Read More

Developing a Research Base for Intravenous Peripheral Cannula Resites

... for this study. This was very much appropriate for this type of study. According to Pildal, et al (2005), Randomized Controlled Trial or RCT is best for medical or health related studies. It ensures efficiency and accuracy as long as the number of subjects are enough to represent the population. In addition, confounding may be prevented by using this type of research method. The control group followed the protocol of transferring the peripheral venous catheter to a different site every 3 days, or as clinically indicated. On the other hand, the intervention group only transferred the peripheral catheter when clinically indicated. The independent variable for this research is relocation of the peripheral venous catheter. Treatment...

Decision Making in Health and Social Care

However, the consumer’s sovereignty does not have meaning if he/she is unable to buy what he/she wants. This paradox is solved through government intervention in the provision of those merit goods such as health care and education. On the other hand, agency theory indicates that conflicts between principals (e.g. shareholders or owners) and agents (e.g. managers) occur as a result of the latter misrepresenting facts and misinterpreting information so that resources can be diverted to uses which they regard as more lucrative. Since principals cannot themselves carry out the task of managing the busi...

Forensic Mental Health

In contemporary society, we do have a moral obligation to treat everyone who enters the criminal justice system fairly. However, there are two aspects of this argument that seem to be developing. On the other hand, someone who does not have control of themselves because of mental illness may need to be seen differently than what has been set for "normal" criminals. The literature points in both directions and this can be a difficult call when people are actually entering the system.

In the current literature, the current criminal justice system has specific ideas of what should be done when an individual commits a crime. As an example, Carvan (1999) poses a question in a case study that is pertinent to the shit study. I...

The Interprofessional Practice and the Health Care System

This is also the position Stone (2007) takes in the quote under discussion.
Furthermore, Stone goes on to declare that Australia has been very slow to implement this practice as compared with other countries and government agencies. One of the primary reasons is that the public policy system in Australia is quite complex and the decision-makers have not come into agreement on where to place it in the policy matrix. This leaves Interprofessional Practice and Education in the dark (or the cold) as far as strategic planning for implementation as well as placing itself within the funding cycles of the government disbursements. (Stone, 2007)
Policies are created in order to put in place how politicians and government official...
