A longitudinal study design involves following the same group of individuals over a period of time, collecting data from them at multiple time points. In this scenario, the same sample of women with breast cancer was followed and data was collected from them at six different times during the first year of living with the disease. Therefore, this study design exemplifies a longitudinal study.
Cross-sectional studies, on the other hand, collect data from different groups of individuals at a single point in time. Retrospective studies involve looking back in time to collect data on events that have already occurred. Correlational studies examine the relationship between variables, but do not involve following a group of individuals over time.
