Design outcomes

Primary

MeasureTime frame
1. Feasibility will be assessed using the following outcome measures: 1.1. Numbers of potential participants who are referred or self-refer to the Clinical Psychologists for eligibility assessment 1.2. The number of people who consent to participate and are randomised to either treatment 1.3. The number of people who remain in treatment 1.4. The time when people drop out 1.5. The number of people who remain in the research irrespective of whether they remain in treatment. 2. The cost of treatment will be assessed using the following outcome measures: 2.1. The number and duration of therapy sessions and the therapist used 2.2. The cost of any patient safety measures used during treatment and up to the 20-week follow up point.

Secondary

MeasureTime frame
All secondary outcome measures will be used at baseline and then 6, 12, 20 and 52 weeks post-randomisation. 1. PTSD symptoms assessed using the PTSD checklist for DSM 5 (PCL-5). This is the likely primary outcome in the subsequent fully powered tria. 2. Impact of the participants' mental health on work, home, social and private leisure activities and interpersonal relationships assessed using the Work and Social Adjustment Scale (WSAS) 3. Recovery from psychosis or mental health problem assessed using the Quality of Process of Recovery scale (QPR) 4. Depression assessed using the Patient Health Questionnaire (PHQ), a self-administered diagnostic instrument 5. Anxiety assessed using the General Anxiety Disorder score sheet (GAD-7) 6. Health status assessed using the EQ5D-5L, a two-page questionnaire with page one consisting of the EQ-5D descriptive system and page two the EQ visual analogue scale (EQ VAS) 7. Health and social services utilisation in terms of number of contacts with general practice, social services, mental health services and other agencies during the past specified period assessed using the FolATED (Use of health and social-service questionnaire), which is a 31-item administered questionnaire 8. Acceptability of both treatments assessed using qualitative interviews with 15-20 participants in both RTM and TF-CBT groups to determine the acceptability and feasibility of participating in the trial and the treatment they received
