Intervening behaviors are changed actions that individuals take intending to improve their health. The most common type of intervention is a clinical trial, in which individuals receive either a new drug, surgery, or device. The main goal of an intervention is to improve individuals' health outcomes by changing their behavior. For example, individuals may be more likely to take their medication if they receive text messages reminding them to do so. Clinical trials are necessary because they help determine whether an intervention is effective and safe for people to use. However, it is also essential to consider the ethical implications of interventions before implementing them. Some interventions may be considered coercive if they involve punishing people for not changing their behavior. Overall, intervening behaviors can be beneficial, but it is essential to consider all factors before implementing them.
