Interventions are not always necessary- people can improve their situation or resolve their problem without an intervention. Sometimes a treatment will not help and may even make things worse.
Interventions can help people improve their situation or resolve a problem, but sometimes those issues can get better without an intervention. Sometimes an intervention may make things worse.
You need to know what would happen without an intervention to decide whether the intervention is needed.
BEWARE when someone says that a “treatment is needed”.
REMEMBER: The treatment might not be needed. Waiting to see what happens is sometimes a better choice.
