Limitation Of Cross Sectional Study

This study is a cross sectional study.

Limitation of cross sectional study. The goal is to look for a meaningful result within an expected boundary. As cross sectional studies measure prevalent rather than incident cases the data will always reflect determinants of survival as well as aetiology 1 unable to measure incidence. List of the disadvantages of a cross sectional study 1.

Cannot be used to analyze behavior over a period to time does not help determine cause and effect the timing of the snapshot is not guaranteed to. Non response is a particular problem affecting cross sectional studies and can result in bias of the measures of outcome. Longitudinal studies may be prospective or retrospective and observational or experimental in design.

The cohort study described in previous questions 3 4 is an example of a longitudinal study that is observational in design. In a longitudinal study each participant is observed at multiple time points thereby allowing trends in an outcome to be monitored over time. Unable to measure incidence.

Recall bias can occur if the study asks participants about past exposures. That means there are fewer risks to manage if tangents begin to develop in the data. The primary limitation of the crosssectional study design is that because the exposure and outcome are simultaneously assessed there is generally no.

Researchers look at specific relationships that happened during a particular moment in time. Associations identified may be difficult to interpret. It is only effective when it represents the entire population.

Two distinct variables are measured at the same point in time. If no such representation exists then the findings from the research will not have validity. This is a particular problem when the characteristics of non responders differ from responders.
