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 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.

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?
