Childhood Obesity Study
The research study titled, "Parents' perceptions and attitudes on childhood obesity: AQ-methodology study" by Akhtar-Danesh et al. (2010) details the perceptions that parents have toward the cause of obesity, how much obesity affects health, and the obstacles that exist in successfully implementing an obesity prevention program for children. Due to the nature of the research experiment, the test that was used was an appropriate method to attain the necessary information. In this particular experiment, the data collection procedures entailed collecting answers from parents by having them answer twenty questions about their feelings on the three aforementioned topics. The data was a convenience sample collected at a Medical Center in Canada (Akhtar-Danesh, 2010). Their subjects consisted of twenty parents that were already available and able to accurately answer their questions. They were asked their opinions in a face-to-face manner and were allowed to answer in any way that they chose to. That is, the data was open-ended and there were no specific leads given by experimenter.
In order to ensure that the protection of the rights of the participants was implemented, a preapproval by the Institutional Review Board was obtained (Akhtar-Danesh, 2010). This means that the researchers underwent a variety of steps in order to assure that the experiment would be ethical, that it would benefit the advancement of science and/or medicine, and that the project would actually give the results that it was supposed to (Babbie, 2010). A research assistant in the particular study at hand explained all of the details of the study directly to the parents so that they would know exactly what it was that they were getting themselves into. The data collection tool used in this study was appropriate for the validity of the study; however, the reliability of the study can be questioned. By asking the parents exactly what their opinions on the subject of childhood obesity were, they were able to get valid answers since the researchers targeted parents that were taking their children to their well-visit checks at the clinic. The reliability however is a bit questionable because the population targeted will not be representative of all parents, as the hypothesis of this particular experiment implies. Since the parents were a convenience sample, the individuals questioned were already concerned with the health of their children, as they were already taking them to a medical environment. The open-endedness of the questionnaire also makes it more difficult to assume complete reliability. If this same experiment were to be repeated in another environment, it would possibly produce different results. In an attempt to remedy these problems, the researchers also implemented a second portion to this test where a convenience sample of one hundred parents from the same clinic were contacted by phone and asked to rank the results from the previous part of the experiment (Akhtar-Danesh, 2010). They were instructed on exactly how to properly rank the information given and were given a consent form in order to follow protocols. The Likert-like scale implemented allowed these parents to rank the responses on a scale of "most disagree" and "most agree." This act in itself took the responsibility away from the researchers and reduced the possible bias that the experimenters could have had in analyzing the results.
The data analysis procedures were appropriate for the data collected because it provided a measurement of something that may have seemed immeasurable. AQ-methodology format allows for qualitative data to be collected and analyzed through quantitative means (Babbie, 2010). The aim of the study was to detect and measure the perceptions of parents toward childhood obesity. Perception in itself implies an abstract thought -- something that is personal, but informative. Solely measuring this concept through statistical tools would be impossible. However, in an attempt to relay unbiased and straight forward information, Q-methodology and factor analysis were the appropriate tools to use. This was the best way to conduct this experiment so that their hypothesis...
