DBT: diary card, chain, and the dialectic

He wants to talk about his mother. The diary card says he cut on Thursday. The target hierarchy is not a suggestion, and holding it warmly is the whole skill.

Before you begin

What Praxical.Psych is, and is not

Praxical.Psych is an educational tool. It teaches the theory, evidence base and clinical method of psychotherapy at the level of an advanced survey course, and it lets you rehearse a complete session in a simulator.

It is not medical, clinical, psychological or legal advice. It cannot diagnose or treat anyone, and it does not state the law where you practise — requirements differ by jurisdiction and change. Nothing here creates a clinician–patient or solicitor–client relationship.

  • Every patient, transcript and case in this app is fictional — a composite written for teaching. None depicts a real person.
  • Praxical.Psych is not therapy, not a substitute for supervision, and not a credential. Competence to practise comes from training, supervised hours and licensure.
  • Scores from the instruments here are for learning how they behave. They are not a diagnosis and not a risk assessment, and must not inform a decision about a real person.
  • Do not enter real patient information. Everything you type stays in this browser, but that is not the same as a compliant clinical record system.
If you are in crisis

In the US and Canada, call or text 988. In the UK and Ireland, call 116 123 (Samaritans). Elsewhere, find a local line at findahelpline.com. In immediate danger, use your local emergency number.
