Interventions, often referred to as interference, involve actions taken to alter a situation or behavior. These can occur in various contexts, such as in healthcare, education, or social services, where professionals implement strategies to improve outcomes for individuals or groups. For example, a therapist may use specific techniques to help a client manage anxiety. In research, interventions are designed to test the effects of a particular change on a population. This could include introducing a new educational program in schools to assess its impact on student performance. The goal is to gather data that can inform future practices and policies.
