Shaping

Domain II · Behavioural & cognitive · B. F. Skinner · 1953

What it is

Shaping is a procedure, not a stand-alone therapy. It slots into ABA programmes, CBT, behavioural activation (BA) and rehabilitation. The core idea is differential reinforcement of successive approximations. The clinician:

Format

• Shaping has no fixed session count. It is a run of steps inside a wider treatment. The phases below combine Miltenberger's procedural steps with Pryor's planning rules.
• Format: Observation or self-monitoring over a few days. In CBT/BA this is the activity and mood diary, usually from session 1–2.

Evidence status, as the guide reports it

• produces direct evidence of competence, which disconfirms beliefs like "I can't do anything";

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• 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

• Steps that are still too big. If a step needs its own staircase, split it.
• Rehearsal that turns into rumination about failure. Keep it concrete and procedural.
• Clients reading the step back as failure. Frame it in advance as a normal part of the method.
• Prompt dependence, where the behaviour only happens when the prompt is given. Fade prompts before you raise the criterion.
• Steady upward drift in the running window shows it is working. It needs reliable measurement and is fiddly without a spreadsheet or app.

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.
