Plain English Summary
Background and study aims
In January 2013, 1.43 million people in the UK received incapacity benefit, many because of mental health difficulties. There is a complex relationship between employment and mental health; poor mental health predicts unemployment, whilst employment leads to improvements in mental wellbeing. Therefore, assisting people with mental health difficulties to get into employment is a priority for the NHS and social care organizations. Personality disorders (PDs) are mental health conditions which affect the way people manage feelings and relate to other people. They are often characterised by intense emotional responses and impulsive high-risk behaviours, meaning that people with a PD often have difficulties developing and sustaining relationships, a necessary skill for both wellbeing and employment. Dialectical behavioural therapy (DBT) is a type of treatment designed to help people who have difficulties managing their emotions through changing thought patterns and behaviour. It is well recognised as an effective treatment for PD. The aim of this study is to test a new treatment programme based on the principles and techniques of DBT can help prepare people with difficulties relating to a PD to find employment. The programme targets areas of difficulty such as managing intense emotions, problematic interpersonal relationships, self-criticism and poor self-management through the development and evaluation.
Who can participate?
Unemployed adults with a personality disorder.
What does the study involve?
Suitable participants are invited to a 60-minute enrolment session where they complete a number of questionnaires about their wellbeing, mood and social functioning. If the participant is still willing to enrol after this session they will be offered a place in one of four DBT-SE groups. All participants who participate in the enrolment session are offered compensation for their time. The DBT-SE groups run for three hours per week (including two 10-minute breaks) for 16 weeks. In between each group participants are given tasks to practice to help consolidate (sum up) what they have learnt during each session. Participants are also asked to fill out a questionnaire and a diary card to help the study team to monitor their employment-related activity. Every four weeks participants are asked to complete additional questionnaires online which take around 30-40 minutes to complete. At the end of the study, participants are invited to take part in a 60-minute interview, to give feedback on their experience of being involved in the study. All participants who participate in the feedback session are offered compensation for their time.
What are the possible benefits and risks of participating?
There is a chance that participants will benefit from taking part by better learning to manage the challenging emotional aspects of looking and applying for work, interviewing, and starting work. Additionally, by learning the skills with a group of people who experience similar difficulties, participants will may benefit from feeling less alone in their own experiences and will have the opportunity to practice their interpersonal skills in a safe and supportive space. It is possible that during the study, participants might get upset if they have recently experienced difficulties in obtaining a job, have recently lost a job, or are having difficulties at work when they enrol. All of the staff working on this study are experienced in facilitating or co-facilitating standard adult DBT skills groups and are trained in how best to support participants if they become upset.

Participants will be screened over the telephone for suitability and if eligible, will be invited to attend a one-hour enrolment session where baseline clinical, psychometric and demographic information will be recorded.
All participants will be offered a place in one of the four DBT-SE groups based at community and hospital locations across the North East London NHS Foundation Trust (NELFT). The intervention will run for 16 weeks and each session will last for 3 hours including two 10-minute breaks. The groups will have staggered start dates, commencing as soon as 12 participants have been recruited.
During the intervention weekly reports of the types of employment seeking activity and the use of DBT-SE skills will be collected from participants. Risk taking behaviour will be monitored weekly in line with standard clinical practice. Participants will also be asked to complete short clinical and psychometric questionnaires every four weeks (duration 30-40 minutes). Four weeks after the end of the intervention participants will be invited to take part in a semi-structured interview to give feedback on their experience of the intervention, psychometric and clinical measures and the referral process.
DBT-SE Attendee Supporters:
Supporters of people with a PD may play a key role in the success (e.g. supportive) or failure (e.g. critical) of their loved one during their search for employment, or during periods when they are unable to work. Furthermore, Supporters may report they experience a burden (financially and/or emotionally) that may reduce their own wellbeing when supporting their loved one through these periods. During the enrolment session, each DBT-SE participant will be asked whether they have a Supporter, and if so, if they think their Supporter would also like to take part in the study. DBT-SE Supporters that take part will be asked to complete a postal survey of demographic, wellbeing and support measures at baseline, i.e. before the DBT-SE participant enters the intervention and at the end as part of the feedback.
Primary outcome measure
1. Referral site and source will be evaluated by analysing the number and speed of referrals received are measured once all DBT-SE groups have started (approximately week 4)
2. Retention rate will be evaluated by analysing the attendance records of each DBT-SE group, logged weekly during the intervention weeks 1-16 and analysed at the end at week 16
3. Willingness of participants to be randomly allocated to a group as part of the main randomised controlled trial is measured via a semi-structured interview at 20 weeks
4. Suitability and acceptability of patient-centered outcomes are measured via a semi-structured interview at 20 weeks
5. Effectiveness and acceptability of an internet-based delivery method for completion of the assessment and outcome measures is assessed via semi-structured interview at 20 weeks
6. Willingness of participants to allow their supporters to be involved in the study measured via a semi-structured interview at 20 weeks
Secondary outcome measures
1. Hours of employment (and employment-related activity) are measured weekly using a diary card from weeks 2-16 and the New Employment Questionnaire (developed for this study) if participants gain employment during the intervention
2. Mood is measured using a number of instruments administered at different time-points across the study:
2.1. Generalised Anxiety Disorder Scale-7 screens for anxiety symptoms, collected at baseline, weeks 4, 8, 12, 16 and at follow-up
2.2. Patient Health Questionnaire-9 screens for depression symptoms, collected at baseline, weeks 4, 8, 12, 16 and at follow-up

2.7. ICEpop CAPability measure for adults measuring capability in the general adult population and is commonly used as part of economic evaluation to index facets of wellbeing, collected at baseline, week 16 and at follow-up
2.8. Social functioning is measured by the Work and Social Adjustment Scale which indexes the impact of mental illness on social functioning, collected at baseline, weeks 4, 8, 12, 16 and at follow-up
2.9. European Quality of Life-Five Dimensions is a health-related quality of life scale (collected at baseline, weeks 4, 8, 12, 16 and at follow-up)
2.10. Christo Inventory for Substance Misuse used to measure the impact of substance abuse on a person’s daily functioning (collected at baseline)
2.11. Support in Employment Questionnaire (developed for this study) indexes the amount of time a participant reports receiving help with employment related activity, collected at baseline, week 16 and at follow-up
3. The use of physical health, mental health, criminal justice and social services is measured by a Service Receipt Inventory (developed for this study) and is collected at baseline, week 16 and at follow-up interview
