According to the interventionists, an intervention
# uses the power of the group against the addict to break through denial and compel him/her to enter treatment
# it does not address psychologic issues nor in intended to. those are dealt with in treatment
# having an experienced interventionist does not hurt. he/she may guide the intervention keeping things on track and not allowing the addict the leeway to manipulate those present.
@ certainly if family members "cave in" to the addict at the intervention, it will not work. even when all goes well, the addict may choose to not enter treatment, or leave treatment prematurely. eveh if this happens, statistically, the chances for success in the future are improved (according to Jeff Jay's book on intervention)
