Long-term effects research focuses on studying the lasting impacts of various factors or interventions on individuals or populations over an extended period of time. This type of research often involves tracking and monitoring participants over months, years, or even decades to understand how certain experiences, behaviors, treatments, or interventions may influence health, development, and well-being in the long term. Long-term effects research can provide valuable insights into the cumulative effects of various factors on individuals' lives and can help inform future interventions, policies, and practices.
