Week 5, Nursing Research

Descriptive research design, mixed methods, and meta-analysis highlighted in Chapter 6. Also, we will review Epidemiology and Longitudinal Studies covered in Chapter 7.
Take a moment to review the listed publications and videos below to  help bring clarity and supplement your course readings as you progress  through our course.
Descriptive Research
Descriptive research is a study designed to depict the  participants in an accurate way. More simply put, descriptive analysis  is all about describing people who take part in the survey.
There are three ways a researcher can go about doing a descriptive research project, and they are:

Observational, defined as a method of viewing and recording the participants
Case study, defined as an in-depth study of an individual or group of individuals
Survey, defined as a brief interview or discussion with an individual about a specific topic

Mixed Methods Research
Mixed methods research (Extracted from the  article below) is the use of quantitative and qualitative methods in a  single study or series of studies. It is a new methodology that is  increasingly used by health researchers, especially within health  services research. There is a growing literature on the theory, design,  and critical appraisal of mixed methods research. However, few papers  summarize this methodological approach for health practitioners who wish  to conduct or critically engage with mixed methods studies.

Mixed Methods

Meta-Analysis
Meta–analysis is a  statistical technique for combining data from multiple studies on a  particular topic. A Meta-analysis is an analytical tool for estimating  the mean and variance of underlying population effects from a collection  of empirical studies addressing ostensibly the same research question.  Meta‐analysis has become an increasingly popular and valuable tool in  psychological research, and significant review articles typically employ  these methods.

Epidemiology
According to the Centers for Disease Control, Epidemiology is  the method used to find the causes of health outcomes and diseases in  populations. In epidemiology, the patient is the community and  individuals are viewed collectively. By definition, epidemiology is the  study (scientific, systematic, and data-driven) of the distribution  (frequency, pattern) and determinants (causes, risk factors) of  health-related states and events (not just diseases) in specified  populations (neighborhood, school, city, state, country, global).

Longitudinal Studies
Longitudinal Study, an epidemiologic study that follows a population  forward over time, evaluating the effects of one or more variables on a  process. If individuals are followed, it is termed a longitudinal  cohort study. If classes—e.g., age classes—are studied, it is a  longitudinal cross-sectional study. Longitudinal studies are the  converse (opposite) of horizontal (parallel) studies.

This week we will have a discussion question that is due. Remember,  your initiation post is due by Wednesday and two follow up responses are  due by Saturday night. Please refer to your course syllabus for the  grading rubric that is required.
Discussion Question – Week Five 
Based on your course reading assignments and your pending research  problem, what type of study do you believe you are conducting, and  please explain why?
