The Personal Concerns Inventory Study (PCI)

Study Overview
=================
Brief Summary
-----------------
Services for people with personality disorders are challenged by how to engage clients in therapy. High non-completion rates have major cost-efficiency implications, but more worrying is that drop-out may be associated with negative outcomes for clients. The investigators have developed a motivational intervention that helps people focus on their valued and attainable life goals and consider how therapy could help with goal attainment.One way to improve retention in treatment is to deliver pre-therapy motivational preparation interviews. The primary aim of our proposed research is to gather information to determine whether a randomised controlled trial of a goal-based motivational intervention is feasible in a community personality disorder treatment service.

Detailed Description
-----------------
The investigators aim to work with community adults with personality disorder. Referrals to Nottinghamshire NHS Trust's community personality disorder service will be eligible for inclusion. After initial assessment for suitability for the service, patients will be randomised to receive the motivational interview plus treatment as usual or treatment as usual only. The investigators aim to recruit 100 participants over 1½ years. The comparison is between a motivational intervention called the Personal Concerns Inventory plus treatment as usual and and treatment as usual only in the client preparation phase. The feasibility measures are (1) the recruitment rate to a goal-based motivational interview plus treatment as usual or treatment as usual only, and (2) the acceptability of the intervention to clients and therapists. The investigators will also develop measures to assess the processes by which the intervention may have an effect, and assess the cost of the intervention compared with treatment as usual.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Goal-based motivational interview<br>Participants randomised to this group will receive the goal based motivational interview - Personal Concerns Inventory (PCI) in addition to treatment as usual. | Behavioral: Personal Concerns Inventory<br>* This is a pre-treatment, goal-based motivational interview which helps to patients identify their life goals, and goal-value. The interview will last approximately 2 hours and will be carried out face to face with a therapist across one or two sessions.<br>|
| Other: Treatment as usual<br>Participants randomly allocated to this group will receive treatment as usual only, ie no specific motivational intervention. | Behavioral: Treatment as usual<br>* No specific motivational interview<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Recruitment | A randomised controlled trial will be considered feasible if the recruitment rate to the project is 54% of all referrals (95% CI 54-64). | 18 months | 
| Acceptability to patients | 80% of clients find the intervention acceptable in terms of its practicability and usefulness (95% CI 80-91) | 18 months | 
| Acceptability to staff | 80% therapists report finding the intervention helpful (95% CI 80-100) | 18 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Treatment Engagement Rating Scale (TER; Drieschner & Boomsma, 2008) | This is a therapist rating scale with items addressing the client's participation, constructive use of sessions, opennness, efforts to change, making sacrifices, goal directedness, and reflection. | 20 weeks after intervention | 
| Client Service Receipt Inventory | Client self-report of receipt of services | 20 weeks after intervention | 
| Treatment attendance | Percentage sessions attended of sessions offered | 20 weeks after intervention |
