An Intervention is when people who are concerned about the behaviors of someone they love, come together and urge the person to seek help. In some cases the people may already have some form of help set up and ready to go. The intervention is done out of concern and love for the person. Their main goal is to help.
Interventions happen most often in cases of drug addiction. For example, if a loved one began spending their child's college fund to buy drugs, their loved ones intervene and try to get it to stop. They urge the individual to seek help and offer support during recovery.
