What it is

Source caveat. The abstract of MacGregor's 1962 Family Process paper (systemagazin's Family Process index) and library catalogue records for the 1964 book confirm the setting (an outpatient adolescent clinic), the format (one family given a team's full resources for about half a week), the…

Format

• Format. One family (the identified adolescent, parents and often siblings) receives the full resources of a team for about half a week, i.e. roughly two to two and a half consecutive days. The work is scheduled in half-day segments. MacGregor's 1962 report gives routine follow-up at 6 and 18…
• Team. MacGregor's 1962 abstract calls it an "orthopsychiatric team" working full time from April 1958, without giving its size. In the usage of the time that implies psychiatry, psychology and social work, which matches the authors' professions (MacGregor, psychologist; Ritchie, social worker;…

Who practises it, and how they are trained or regulated

• Status today: MIT is mainly a historical model. Harold Goolishian played a central role in developing it in the 1950s, and it was one of the earliest federally funded family therapy projects. No current certification, licence or fidelity programme was found. Its lineage runs through the Galveston Family Institute (1978), now the Houston Galveston Institute, which today teaches collaborative-dialogic practice rather…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Does it use a device, heat, cold, water or a physical procedure? Has a medical professional checked that it is safe for you?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• The family seeing the worker as an enforcer (court, child protection). Clarify the worker's role openly.
• Families attributing change to the team instead of to themselves; deterioration requiring a higher level of care.
• A parent refusing to come; agreement "only for the child's sake"; an unresolved safety issue. It is working when all members commit to the full block.
• Escalation beyond what the session can contain; a scapegoat being re-targeted. It is working when there is a direct exchange that differs from the usual pattern.
• Breaches of what a member asked to keep private; parents feeling ambushed. It is working when parents engage with the other person's view instead of rebutting it.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
