CORAL Study: Proof of Concept Trial

Study Overview
=================
Brief Summary
-----------------
A decision aid tool (DAT) to assist mental health service users in reaching disclosure decisions in the context of employment was developed in a previous study (IRAS REC ref: 07/Q0706/21). The initial feasibility and acceptability was assessed in a group of 15 mental health service users with mean decisional conflict scores reduced from 51.98 to 35.52 after completion. 60% of participants reported that the DAT was quick to complete, 40% that it was easy, 60% that it was relevant and 80% that they would definitely or probably use it in making disclosure decisions. This current study (CORAL: Proof of concept RCT) aims to determine whether a full randomised controlled trial of the DAT is justifiable and feasible, and to optimise its design. This will consider: 1) effects of the intervention; 2) baseline predictors of disclosure; and 3) exploration of the relationship between use of the DAT and the rate of disclosure. Eighty people who are on the caseload of a vocational specialist working with people with mental illness will be included in this study. All participants will be receiving treatment from an Improving Access to Psychological Therapies (IAPT) service or a Community Mental Health Team (CMHT). An equal number from each group will be allocated to receive either the DAT intervention or treatment as usual. Individuals from both groups will complete baseline assessment and 3month followup assessments. Those allocated to the intervention will also complete an assessment immediately following the intervention. Qualitative interviews will also be conducted at 3 months with a maximum of 15 people from the intervention group and 6 people from the control group.

Detailed Description
-----------------
The principal aims are to determine whether a full randomised controlled trial of the CORAL decision aid tool is justifiable and feasible and to optimise its design. Specific objectives are as follows: To examine the effect of the DAT on decisional conflict regarding disclosure both immediately and at 3 months post first use. To collect data to inform sample size calculations for the primary outcome measures for use in a future full scale trial(gaining employment and workplace accommodations). To test study procedures, including the sample that can be drawn using the inclusion and exclusion criteria; the full time equivalent needed for research assistants to recruit sufficient numbers and carry out the study procedures in the time available; and whether the measure leads to too much respondent burden. To pilot the use of a questionnaire on employment and disclosure related activities. To test the selected randomisation method, in this case individual level randomisation, including the methods for avoiding and measuring contamination. To pilot recruitment and retention methods for service users and vocational specialists. To estimate effect sizes and their confidence intervals for employment related activities (proxy outcome measures for gaining employment and workplace accommodations), in order to determine whether a full scale trial is justified. To modify the conceptual model

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Decision Aid Tool<br>Intervention group - receives the decision aid tool in booklet form and is introduced to it by an investigator. | Behavioral: Decision Aid Tool<br>* A booklet which outlines to pros and cons of different decision outcomes, and is designed to assist the user in making a decision according to their own specific circumstances<br>|
| No Intervention: Control<br>The control group does not receive a copy of the decision aid tool booklet, instead received treatment as usual from vocational specialist | Other: Treatment as Usual<br>* The control group does not receive a copy of the decision aid tool booklet, instead received treatment as usual from vocational specialist<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| decisional conflict scale | Decisional conflict scale (O'Connor, 1993) This measures personal perceptions of uncertainty, lack of clarity and effectiveness in decision making. Has 16 items with each rated on a 5 point Likert scale ranging from 0=strongly agree to 4=strongly disagree. | Change from baseline in decisional conflict at 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sociodemographic data | Socio-demographic and clinical data to be collected as part of the baseline interview will include age, gender, years since first contact with mental health services, education, employment status and history, housing arrangements, source of income, current mental health care, knowledge of clinical diagnosis, agreement with diagnosis and information on social networks. | baseline | 
| Employment related questions | To record how many jobs applications, apppointments with vocational specialists, training days and job applications the participant has completed in the preceeding 3 months. | baseline and 3-month follow up | 
| Discrimination and Stigma Scale (DISC) | scale to assess mental health service users' experiences of discrimination. 22 items. Baseline assesses if discrimination/stigma has ever been experienced, 3 month follow-up asks if discrimination/stigma as been experienced in the past three months.

| Questionnaire on Anticipated Discrimination (QUAD) | The QUAD is a self-complete measure which contains 17 items which address 'areas of anticipated discrimination'. This asks participants to provide a rating of whether they expect to be treated unfairly in various areas of life. Each item is scored on a five point Likert scale ranging from 0 (Strongly disagree) to 4 (Strongly agree). Brohan E, Clement S, Thornicroft G.

| Boston University Empowerment Scale (BUES) | This 28-item scale was developed with an emphasis on service user-involvement at all stages of design and testing. This version has shown adequate internal consistency (α=.86). Rogers, E. S., Chamberlin, J., Ellison, M.

| Internalised Stigma of Mental Illness Scale (ISMI) | The ISMI is a 29-item measure that assesses mental health service users' experience of internalised stigma. It is composed of 5 sub-scales: Alienation, Stereotype Endorsement, Perceived Discrimination, Social Withdrawal and Stigma Resistance. Strong internal consistency (α = 0.90) and test-retest reliability(r=0.92) have been reported Ritsher JB, Otilingam PG, Grajales M.

| Perceived Devaluation and Discrimination Scale (PDD) | The PDD is a 12-item, uni-dimensional, scale which measures the extent to which a person believes that people will devalue or discriminate against those with a mental illness. This scale has been widely used and has excellent psychometric properties Link, B.G., Neese-Todd, S., Asmussen, S. & Phelan, J.C. (2002). On describing and seeking to change the experience of stigma.

| Stigma Coping Orientation Scales | Measures to assess approaches to coping with the stigma associated with mental illness. Revised versions of four of the scales are now available and will be used in this study. These are secrecy (5-items alpha = .85), withdrawal (5-items alpha = .71), challenging (5 items alpha = .75) and distancing (3 items alpha = .62) (Bruce Link, personal communication).
