Design outcomes

Primary

MeasureTime frame
Levels of symptoms of PTSD are measured using the Child Revised Impact of Event Scale (CRIES-8) completed at baseline and at 2.5, 5 and 11 months post-randomisation.

Secondary

MeasureTime frame
1. PTSD severity is measured using the Children’s PTSD Symptom Scale for DSM-5, interviewer version (CPSS-I-5), at baseline, 5 and 11 months 2. Self-reported PTSD severity is measured using the Child and Adolescent Trauma Screen (CATS), with additional items addressing dissociation and complex PTSD symptoms at baseline, 2.5, 5 and 11 months. 3. Anxiety and depression are is measured using the Revised Child Anxiety and Depression Scale (RCADS) at baseline, 5 and 11 months 4. Suicidal ideation is measured using selected items from the Mood and Feelings Questionnaire (MFQ) at baseline,5 and 11 months 5. Irritability is measured using the Affective Reactivity Index (ARI; child and parent-report versions) at baseline, 5 and 11 months 6. Child’s overall severity and functioning is measured using the Children’s Global Assessment Scale at baseline, 5 and 11 months 7. Parent reported mental health and well-being measured using the Strengths and Difficulties Questionnaire at baseline, 5 and 11 months 8. Personality traits are measured using the McLean Screening Instrument (caregiver version) at baseline, 5 and 11 months 9. Quality of life is measured using the Youth version of EuroQol EQ-5D (EQ-5D-Y) at baseline, 5 and 11 months Health economic outcomes: 1. Resource use is measured using the Child and Adolescent Service Use Schedule (CA-SUS) at baseline, 5 and 11 months 2. Views of the young people, their families and clinicians will be captured using qualitative interviews when therapy has been concluded (for participants and family members) or after the trial data collection has concluded (for service managers and commissioners). 3. Cost-effectiveness of CT-PTSD will be assessed using CA-SUS and EQ-5DY (as above) and additional data will be collected directly from clinicians and service records regarding CT-PTSD and TAU contact time and indirect time. If resources allow, an additional 29 month follow up assessment will take place, where the CRIES-8, CPSS-I-5, CATS, RCA
