Week 8 Discussion: Participation in Research
Jane, a military psychologist, wants to examine two types of treatments for depression in a group of military personnel who have suffered the loss of their legs. She has only 20 men to work with.
What would be the best research design for the study and why?
I think that Jane should use the with-in study because she has 20 subjects that can be divided into two groups, that way she can conduct one experiment on both groups exposing them to all the different conditions for the independent variable in her study (Lewandowski et al., 2019).
What are some issues that Jane needs to consider before starting the study?
Jane should consider getting written consent from all participants, do a literature review about depression, consider factors that can influence the outcome of the study, and develop good research questions, and form a hypothesis (Lewandowski et al., 2019).
What is a longitudinal study?
A longitudinal study is an observational study that is conducted on the same subjects over weeks, months, or even years to detect any changes that may occur.
What are the benefits and challenges associated with a longitudinal study?
The benefits of this type of study are that it allows a researcher to observe their subjects in real-time so that the researcher can better establish a sequence of events that will allow the researcher to gain insight into the cause-and-effect relationships. It also allows the researcher to eliminate the risk of recall bias (Lewandowski et al., 2019).
The challenge of a longitudinal study is that these types of studies are time-consuming and expensive, they require a significant commitment and resources to be effective.
These studies run the risk of participants dropping out of the experiment which will result in the conclusion of the study being invalid (Lewandowski et al., 2019).
