Quick answer

Both can work. The right one depends on the risk.

In an invitational intervention, the person is told ahead of time and invited to a family meeting. In a surprise intervention, the family meets first and the person learns about it when they arrive.

Neither one is an ambush when it is done well. Both are planned, calm and respectful.

Invitational intervention

The family tells the person there will be a meeting about their drinking or drug use. They are invited to come. Many families prefer this because it feels honest.

It often fits when: the person still talks to the family, there is no immediate danger, and they may agree to listen.

Surprise intervention

The family prepares with the interventionist first. The person is not told until the meeting starts.

It often fits when: the person has refused every conversation, would leave or disappear if warned, or is in danger now.

What both need

  • A plan, made with the family before the meeting
  • A treatment bed ready, so the person can go the same day
  • Clear, kind letters from family members
  • Boundaries the family will keep if the answer is no
  • A trained person to lead it

What about CRAFT?

CRAFT (Community Reinforcement and Family Training) is a slower approach. Families learn new ways to respond over weeks or months. It can help when there is time. When there is danger now, most families need a direct intervention.

How Craig helps you decide

On the first call, Craig asks about safety, history and what has already been tried. He explains the options in plain words and helps your family choose. He is trained in both harm reduction and tough love, and he leads every intervention himself.

I was struggling with alcohol addiction, and I was not willing to get help. He talked with my family, drove all the way from Vancouver Island to Kelowna to pick me up, sat with me and talked me into going to Together We Can for treatment. Because of him, I went.
