jats:titleAbstract</jats:title>jats:secjats:titleObjective</jats:title>jats:pThere is a dearth of practice‐based evidence of adapted or ‘<jats:styled-content style="fixed-case">DBT</jats:styled-content>‐informed’ transdiagnostic models, which could provide services and clinicians with information of what works and for whom, in which settings. This paper aims to bridge this gap by exploring the client experience of a 12‐week transdiagnostic dialectical behaviour therapy (<jats:styled-content style="fixed-case">DBT</jats:styled-content>) group programme in a private psychiatric hospital.</jats:p></jats:sec>jats:secjats:titleMethod</jats:title>jats:pFive participants with varied clinical diagnoses and previous therapeutic experiences were interviewed following completion of one or more of the same adapted <jats:styled-content style="fixed-case">DBT</jats:styled-content> programme, comprising of the standard four modules over 12 weeks, including a weekly skills group and 1:1 therapy. Interpretative phenomenological analysis (<jats:styled-content style="fixed-case">IPA</jats:styled-content>) was applied to give voice to the clients’ lived experience of the group.</jats:p></jats:sec>jats:secjats:titleResults</jats:title>jats:pThree master themes were identified: ‘Pre <jats:styled-content style="fixed-case">DBT</jats:styled-content>: Crisis & Desperation’; ‘In‐session: Belonging’; and ‘The Real World: Living’, each characterised by four sub‐themes, highlighting helpful and hindering factors of clients’ current and previous therapeutic experiences.</jats:p></jats:sec>jats:secjats:titleConclusion</jats:title>jats:pOverall this version of <jats:styled-content style="fixed-case">DBT</jats:styled-content> in a transdiagnostic setting was experienced as helpful and positive by participants; main outcomes included being able to build a life worth living, feel hope and joy, build <jats:styled-content style="fixed-case">DBT</jats:styled-content> skills into a lifestyle, and develop reflective practice. Implications for clinical practice, service delivery and policy are also discussed. The article aims to provide clinicians with practice‐based evidence to inform the delivery of <jats:styled-content style="fixed-case">DBT</jats:styled-content> as well as supporting the case for the use of <jats:styled-content style="fixed-case">DBT</jats:styled-content> with various disorders, thus paving the way for future research in this area.</jats:p></jats:sec>
