Plain English Summary

Background and study aims
The aim of this study is to find out whether a new psychological intervention, Dialectical Behavioural Therapy Skills for Employment (DBT-SE), is more effective than support provided by Mental Health Employment Services (MHES) in helping people who experience difficulties consistent with a personality disorder (PD) to gain and retain paid employment. The study is part of a wider research programme “Enabling and Motivating People (with a personality disorder) in Occupation Wellbeing Education and Responsibility (EMPOWER)” funded by the National Institute for Health Research (NIHR). It is important to develop recovery-focused services to help to tackle the challenges of employment for people with mental health problems. People with a PD have complex needs and while therapeutic interventions result in improved mental health, their vocational outcomes remain comparatively poor. This suggests that targeted vocational interventions are vital for improving the lives of people with a PD. DBT-SE is an intervention that focuses on identifying and modifying the emotional, cognitive, and behavioural factors which lead to poor self-management and interpersonal difficulties in the workplace. It will be delivered by healthcare professionals in NHS Trusts and Third Sector Organisations that provide mental health support services (e.g. Mind).

Who can participate?
Participants are eligible if they report difficulties consistent with a PD; are of working age but not currently working (or working limited hours for limited salary/medically certified unfit to work due to mental health); eligible for work in the UK; available for employment and able to verbally communicate in English.

What does the study involve?
Participants are randomly allocated to either DBT-SE plus Treatment as Usual (TAU) or MHES plus TAU. DBT-SE participants attend 3-hour group sessions for 17 weeks. The services MHES participants receive vary between organisations but typically include support in employment preparing activity, motivation, skills development, and managing mental health difficulties.

What are the possible benefits and risks of participating?
All participants will be invited to attend an employment workshop to discuss some of the practical skills needed for seeking or returning to work. All participants will be issued with an employment manual written by a vocational advisor. This manual contains advice on the practical aspects of employment. Participants getting DBT-SE will attend training sessions where skills to manage the challenging emotional aspects of looking for and applying for work, interviewing, and starting work will be discussed each week. Participants getting MHES will be supported by a vocational advisor who is an expert at helping people to gain employment or return to work. Regardless of the support received (DBT-SE or MHES) it is hoped that what participants will learn will help them to manage emotions and relationships better in their home life, which may also improve their wellbeing. Participants will be compensated for their time when they are contacted after the initiatives have ended. At the 6 and 12 month follow ups participants are given £20 in high street shopping vouchers (£40 in total). Participants will contribute to NHS research designed to support people into employment in the future. There may not be an immediate direct benefit to participants but it is hoped that participating will helps them on their path to employment. There is a possibility that participants could get upset when discussing their experiences or completing the research questionnaires. It is also possible that they may experience disappointment if they are not able to obtain employment quickly. Participants will be given information on how to stay safe if they do experience distress and are provided with the contact information of organisations they can telephone if they need to speak with someone. If their distress is ongoing they are encouraged to contact their healthcare professional (if they have one) or GP.

Scientific titleA randomised controlled trial evaluating the efficacy of Dialectical Behavioural Therapy Skills for Employment (DBT-SE) compared with a referral to a mental health employment specialist for people with difficulties consistent with a personality disorder (PD)
Study acronymAn RCT of DBT-SE for PD
Study hypothesisThe researchers plan to conduct a randomised controlled trial (RCT) to evaluate whether a new psychological intervention, Dialectical Behavioural Therapy Skills for Employment (DBT-SE), is more effective than support provided by Mental Health Employment Services (MHES) in helping people who experience difficulties consistent with a personality disorder (PD) to gain and retain paid employment. The RCT is part of a wider research programme “Enabling and Motivating People (with a personality disorder) in Occupation Wellbeing Education and Responsibility (EMPOWER)” funded by the National Institute for Health Research (NIHR).

It is important to develop recovery-focused services to help to tackle the challenges of employment for people with mental health problems. People with a PD have complex needs and while therapeutic interventions result in improved mental health, their vocational outcomes remain comparatively poor. This suggests that targeted vocational interventions are vital for improving the lives of people with a PD.

2. Registered with a UK GP: Willing and able to provide details of the GP practice they are registered with for safety reasons
3. Working age: Minimum 18 years old
4. Not currently working or working limited hours for limited salary:; (i) Unemployed, (ii) Certified medically unfit to work by GP for a minimum of 4 weeks (by randomisation date) with no planned return to work within the next 3 weeks or (iii) Fulfils the Government requirements for permitted work or supported permitted work, current guidance : working fewer than 16 hours per week, AND, earn less than £131.50 per week (N.B. this will be updated during the study in line with changes to UK government guidelines)

6. Available for employment: No commitments that preclude employment (e.g. sole carer for family member/infant who cannot be cared for by another person, full-time student)
7. Able to verbally communicate in English and basic reading and writing skills: The intervention is delivered in English so participants will need to be comfortable conversing with other group members. As the intervention uses handouts and homework sheets they will need to have basic reading and writing skills
Participant exclusion criteria1. Florid Psychotic Disorder/symptoms of Psychosis: Measured through seven screening questions adapted from the SCID I. The presence of symptoms implies the volunteer is not suited to the programme and may not have the capacity to consent
2. Has received full or modified/adapted DBT during the last 12 months: It would not be appropriate to offer more DBT so soon after treatment ends
3. Suicide attempt within the last 12 weeks: Each participant will be questioned regarding suicidal behaviour, where there have been recent (< 12 weeks) incidents of suicidal behaviour the participant will not be permitted to volunteer for the study. This is because the needs of the participant are greater than the study is equipped to support
4. Incident of deliberate self-harm within the last 4 weeks: Each participant will be questioned regarding self-harming behaviour, where there have been recent (< 4 weeks) incidents of self-harm the participant will not be permitted to volunteer for the study. This is because the needs of the participant are greater than the study is equipped to support
5. Bipolar Disorder diagnosis/ currently in treatment for Bipolar Disorder (Includes being diagnosed with Bipolar Disorder but not currently receiving treatment): A diagnosis of Bipolar Disorder or pharmacological or Psychological treatment for bipolar disorder implies the participant has needs outside of the remit of the study
6. PD symptoms due to a head injury: Difficulties are not due to a mental health problem but an organic injury
7. Unable to travel to DBT-SE site or MHES site: Participants need to be willing and able to travel to either site
8. Receiving a psychological therapy as part of a research study unrelated to EMPOWER: Participants receiving a novel treatment as part of research will be excluded as it will not be possible to accurately quantify and characterise the treatment. If the research intervention will be over before the participant attends baseline data collection and randomisation they will be permitted to join the study but will not if the two could overlap
