The drawback to cross-sectional studies is the inability to express cause and effect relationships between the variables being tested. Or to make a convincing observation in regards to the course of the connection between variables.It is because of the concept of the snapshot at the single moment, that prevents the consideration of before and after that specific moment is analyzed (What researchers mean by cross-sectional vs. longitudinal studies.,2009). As it relates to longitudinal studies, they are observational as well. However, it is over an extended period. Like cross-sectional studies, the researchers are not entering with the participants or respondents. This method studies the same subjects several times over a period of years.
