Evaluating Purpose Statements

There is a link between understanding the purpose of one's research and selecting the appropriate methods to investigate the questions that are derived from that purpose.
-(Newman, Ridenour, Newman, & DeMarco, G. M. P., Jr., 2003, p. 169)
Post a critique of the research study in which you:
Evaluate the purpose statement using the Purpose Statement Checklist as a guide
Analyze alignment among the theory, research problem, and purpose
Explain your position on the relationship between research and social change

...m a small study revealed that, "behavioral beliefs and normative beliefs were predictive of self- reported hand hygiene performance." But because of the study being small-scale, it was not generalizable. This study's intent is to replicate the smaller study in a larger scale with data having been selected randomly so as to make the results generalizable.

Does the statement mention the participants?
In generally yes as I believe it's part of the variable "random sample of workers in a public university setting and not to a general public.

Does the statement mention the research site?
Yes. While the university was not fully named, the study indicated that an online, voluntary, anonymous survey was launched and participated by 1600 full-time employees of a Midwestern University that had 5504 workers. Thus, the research site was online but the participants selected where from a specific organization, forming a specific subpopulation in an academic community that has a physical site in the Midwest.

Is the statement framed in a way that is consistent with the identified problem?
Yes. The problem the article presents is in relation to illnesses in the workplace result from hand hygiene and its impact in our work environment. The authors indicated a particular smaller study that has undertaken this problem but explains its non-generalizability because of its limitations. The authors framed their study against that smaller study - to achieve 2 purposes in relation to TBP, hand hygiene and current interventions in place. The methods they utilized were selected with a view to incorporate random selection of participants and collected data, even when measuring attitudes. The purpose statement is therefore consistent with the methods selected and the problem under investigation.

If the study is quantitative, does the purpose statement do as follows?
If by this, the question is about the purpose statement indicating the quantitative nature of the study, then the answer is yes - the purpose statement provides an indication. This is indicated in the words - 'random, sample, self-reported, understanding' utilized in the short purpose statement.

Identify the variables under study
The variables used are as follows:
1. Hand hygiene behaviors
2. Demographic characteristics of participants (gender, age, position/role, ethnicity, income, number of workdays, illness, education, flu-shots, income, etc.)
3. Self-beliefs of participants in relation to protective hygiene

Provide a general definition of each key variable
1. Hand hygiene behaviors - the behaviors of participants in relation to hand hygiene - when they clean, how they clean, what they ...
