Solution Summary

The discussion in this work focuses on the appropriate application of quantitative research study designs for various applications in health research, with examples.

Bipolar Disorder
A mental health disorder is often diagnosed using the guidelines prescribed in the DSM-V manual. A descriptive design seeks to understand a situation or phenomenon, so there is no hypothesis formed prior to conducting research. The researcher may use techniques such as personal interview or observation to make conclusions about how a particular therapy affects people diagnosed with bipolar disorder, for example.

A different researcher may want to evaluate the effectiveness of a medication, in controlling the symptoms of BPD. The researcher could assess severity of symptoms, apply a control and treatment group (with a new medication being given to the randomly selected treatment group members), then reassess for symptoms, using a measurement scale. Statistical evaluation is then used to determine a cause and effect relationship between taking the medication and decreased severity of symptoms, in a quasi experimental design.

In a correlation study, the researcher may want to investigate whether a correlation exists between two variables. For instance, the researcher may want to know if a correlation exists between diagnosis of BPD and body ...
