219 ‒ Dialectical behavior therapy (DBT): skills for overcoming depression & emotional dysregulation

KEYPOINTS

• 01

  DBT grew out of CBT's failures with chronically suicidal patients.

  Rizvi, director of the DBT clinic at Rutgers and a former student of Marsha Linehan, explains that Linehan began in the 1970s trying to apply standard cognitive behavioural therapy to people who were chronically suicidal. CBT's heavy emphasis on change left these patients feeling invalidated — as if their suffering were being dismissed — and many dropped out.

• 02

  The core dialectic is acceptance and change.

  Linehan's insight was to balance change-oriented behavioural strategies with acceptance strategies drawn from Zen practice. 'Dialectical' means holding two seemingly opposite truths and finding a synthesis rather than a mushy compromise.

• 03

  Psychotherapy trials often exclude the hardest patients.

  Rizvi explains the standard randomized trial — say, 12 weeks of CBT versus nothing or treatment as usual — used narrow inclusion criteria, often excluding suicidal or complex patients. CBT works well for many, but not for everyone, and evidence often doesn't generalize to those excluded.

• 04

  Linehan was, in effect, her own index case.

  Linehan was hospitalized in her late teens or early 20s, received a lot of treatment, and only went public about her struggles in a New York Times piece around 2010–2011. Attia compares her synthesis to Bruce Lee's Jeet Kune Do, built from over 30 martial arts by keeping what was useful and discarding what wasn't.

• 05

  Borderline personality disorder is fundamentally emotion dysregulation.

  People experience intense, uncontrollable, rapidly shifting emotions — affective lability — that drive behavioural dysregulation such as substance use, reckless spending, impulsive sex and driving. Chronic self-injury or suicide attempts appear in more than 75% — in some studies 90–95% — of people meeting criteria. Rizvi believes men are underdiagnosed and must be more severe to receive the diagnosis.

• 06

  'Wise mind' synthesizes emotion mind and reasonable mind.

  Conflict often arises when one partner is in emotion mind and the other in reasonable mind. Wise mind asks what is valid in each and seeks a synthesis.

• 07

  Radical acceptance reduces suffering without condoning.

  Rumination — 'if only I'd left 15 minutes early' — adds suffering to pain. Accepting that nothing can change the present moment can bring distress from 100 down to around 50; if a problem recurs, change strategies address prevention later.

• 08

  DBT teaches skills in several domains.

  Mindfulness (capacity to be aware of the present), interpersonal effectiveness, emotion regulation and distress tolerance are the core four; a fifth set of self-management skills was in the 1993 manual and now appears as 'walking the middle path', developed for adolescents and families by Jill Rathus and Alec Miller.

• 09

  Chain analysis and vulnerability factors reveal what drives problem behaviour.

  A chain analysis maps the events, thoughts and feelings leading to a target behaviour like exploding in anger. Vulnerability factors — poor sleep, an overloaded schedule, physical pain — make negative emotions more likely, and treating them can make life run more smoothly.

• 10

  Opposite action changes unwanted emotions.

  Simple in concept, hard to execute: act opposite to the urge. If anxiety urges avoidance, approach; and do it all the way — a fake smile doesn't work.

• 11

  DBT skills help people without a diagnosis.

  Attia, who meets no DSM-5 criteria, credits DBT with transforming his anger. Rizvi wonders whether low-dose interventions like skills videos might help many people before they need intensive therapy, though evidence is still emerging.

• 12

  Distress tolerance is about surviving the moment, not solving it.

  When distress is at 90 on a 0–100 scale, Rizvi says, people are not taking in information or learning much, so the first goal is to bring arousal down. Skills such as mindfulness and acceptance make an unchangeable moment more bearable; problem-solving and prevention come later, once the person can think clearly. This is why DBT separates crisis skills from change skills.
