The Mini Nutritional Assessment MNA is a widely used measure for assessing nutritional status in patients with stroke. Knowledge of the relationship between nutritional status and quality of life QOL could guide clinicians to improve QOL in patients with stroke more effectively. A repeated-assessments design 1 week apart was used to examine the test-retest reliability of the MNA. Results The intraclass correlation coefficient for the MNA was 0. The minimal detectable change and percentage of minimal detectable change for the MNA were 2. Conclusions The MNA has satisfactory test-retest reliability that is useful for repeatedly assessing the nutritional status of patients with stroke. The MDC of the MNA has acceptable random measurement error which is useful for determining whether the change score of a patient is outside the range of random measurement error.

Main article: Documentary research Steps in conducting research[ edit ] Research is often conducted using the hourglass model structure of research.

The major steps in conducting research are: [30] Identification of research problem Specifying the purpose of research Determining specific research questions Specification of a conceptual framework , sometimes including a set of hypotheses [31] Choice of a methodology for data collection Data collection Analyzing and interpreting the data Reporting and evaluating research Communicating the research findings and, possibly, recommendations The steps generally represent the overall process; however, they should be viewed as an ever-changing iterative process rather than a fixed set of steps.

Often, a literature review is conducted in a given subject area before a research question is identified. A gap in the current literature, as identified by a researcher, then engenders a research question.

The research question may be parallel to the hypothesis. The hypothesis is the supposition to be tested. The researcher s collects data to test the hypothesis. The researcher s then analyzes and interprets the data via a variety of statistical methods, engaging in what is known as empirical research.

The results of the data analysis in rejecting or failing to reject the null hypothesis are then reported and evaluated. At the end, the researcher may discuss avenues for further research. However, some researchers advocate for the reverse approach: starting with articulating findings and discussion of them, moving "up" to identification of a research problem that emerges in the findings and literature review. The reverse approach is justified by the transactional nature of the research endeavor where research inquiry, research questions, research method, relevant research literature, and so on are not fully known until the findings have fully emerged and been interpreted.

Rudolph Rummel says, " It is only when a range of tests are consistent over many kinds of data, researchers, and methods can one have confidence in the results.

This process takes three main forms although, as previously discussed, the boundaries between them may be obscure : Exploratory research , which helps to identify and define a problem or question.

Constructive research , which tests theories and proposes solutions to a problem or question. Empirical research , which tests the feasibility of a solution using empirical evidence.

There are two major types of empirical research design: qualitative research and quantitative research. Researchers choose qualitative or quantitative methods according to the nature of the research topic they want to investigate and the research questions they aim to answer: Qualitative research This involves understanding human behavior and the reasons that govern such behavior, by asking a broad question, collecting data in the form of words, images, video etc.

This type of research aims to investigate a question without attempting to quantifiably measure variables or look to potential relationships between variables. It is viewed as more restrictive in testing hypotheses because it can be expensive and time-consuming and typically limited to a single set of research subjects. Quantitative research This involves systematic empirical investigation of quantitative properties and phenomena and their relationships, by asking a narrow question and collecting numerical data to analyze it utilizing statistical methods.

The quantitative research designs are experimental, correlational, and survey or descriptive. Quantitative research is linked with the philosophical and theoretical stance of positivism.

The quantitative data collection methods rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories.

If the research question is about people, participants may be randomly assigned to different treatments this is the only way that a quantitative study can be considered a true experiment. If the intent is to generalize from the research participants to a larger population, the researcher will employ probability sampling to select participants.

Primary data is data collected specifically for the research, such as through interviews or questionnaires. Secondary data is data that already exists, such as census data, which can be re-used for the research.

It is good ethical research practice to use secondary data wherever possible. For example, a researcher may choose to conduct a qualitative study and follow it up with a quantitative study to gain additional insights.

As such, non-empirical research seeks solutions to problems using existing knowledge as its source. This, however, does not mean that new ideas and innovations cannot be found within the pool of existing and established knowledge.

Non-empirical research is not an absolute alternative to empirical research because they may be used together to strengthen a research approach. Neither one is less effective than the other since they have their particular purpose in science.

Typically empirical research produces observations that need to be explained; then theoretical research tries to explain them, and in so doing generates empirically testable hypotheses; these hypotheses are then tested empirically, giving more observations that may need further explanation; and so on.
