Longitudinal and/or cross-sectional research are necessary to determine how disorders change and progress over a typical patient's lifetime. This involves tracking patients over a period of time to gather data on how their symptoms, behavior, and overall health develop or worsen. This information is important to inform treatment decisions and adjust interventions as needed. Genetic and environmental factors may also be studied in longitudinal or cross-sectional research, but the primary purpose is to observe changes over time in individuals with a particular disorder.
