Online PTSD Treatment for Young People and Carers - Case Series (OPTYC)

Post Traumatic Stress Disorder (PTSD) is prevalent and impairing in children and young people. Effective face to face treatments exist, including Cognitive Therapy for PTSD (CT-PTSD), developed by the researchers' group. However, few young people access effective treatments.

The researchers are therefore developing a website and smart-phone App that will improve accessibility of this treatment by allowing trained therapists to deliver CT-PTSD over the internet (iCT) to young people (12-17 years old) with PTSD. This study aims to provide an initial evaluation of iCT. This will be done by running an uncontrolled case series with 6 young people.

The objectives of the case series are to: to gauge acceptability of the programme to young people, carers, and therapists; to measure adherence to the programme; to test the battery of measures for acceptability; and to obtain estimates of clinical change.

Study Overview

• Status: Unknown
• Conditions: Post Traumatic Stress Disorder
• Intervention / Treatment: Behavioral: internet-delivered Cognitive Therapy for PTSD (iCT)

Detailed Description

PTSD is prevalent among young people, and is distressing and impairing. Face-to-face trauma-focussed CBT (TFCBT) is an effective short-term therapy for PTSD in young people. The researchers previously developed Cognitive Therapy for PTSD (CT-PTSD) in children and young people, and have shown in 2 published RCTs that it is efficacious when delivered face-to-face. However, most young people with PTSD do not receive effective, evidence-based treatments. This is in part due to under-capacity in NHS CAMHS, and in part due to the burden and inconvenience to young people in attending face-to-face appointments in a clinic. In this project the researchers propose to make CT for PTSD widely available to young people by delivering the therapy via the internet, with therapist support. The rationale for this approach is that (1) young people will engage with internet-delivered therapy, and online therapies for other disorders such as depression have demonstrated efficacy in clinical trials; (2) effective online therapies for adults with PTSD have been developed and evaluated; (3) no online treatments for young people with PTSD have yet been developed.

An uncontrolled case series will be run with N=6 young patients. Young people who are referred to the South London and Maudsley NHS Foundation Trust CAMHS service, and who meet the eligibility criteria, will be invited to take part in the case series. After both the young person and their carer or parent have provided informed consent (or assent), they will complete several baseline assessment measures. These measures will be completed at a face-to-face meeting in the Tier 4 National and Specialist Trauma, Anxiety and Depression (TAD) NHS clinic, and online. The young person and family will meet the young person's therapist face-to-face at this initial assessment meeting. After assessment, the young person that will be treated remotely using iCT for up to 12 weeks.

This treatment will include regular (at least weekly) telephone contact with the therapist, and other contact with the therapist during the week using a messaging function within the iCT App. The young person will be asked to complete a mood rating and a brief 8-item questionnaire about PTSD symptoms once a week during treatment: this mirrors what happens during standard face-to-face care in the TAD NHS clinic. At mid treatment, the young person will be asked to complete one additional 25-item questionnaire about thoughts related to trauma. Risk monitoring including monitoring of adverse events will be carried out during weekly phone calls.

Post treatment, the young person will attend the TAD NHS clinic for a face-to-face clinical interview and will complete a questionnaire pack online. At this meeting, the young person will complete feedback ratings on the acceptability of the design of online treatment modules using 4 simple 0-10 scales (about the overall design appeal, ease-of-use, comprehension, and likelihood of recommending the program to a friend with similar problems). The young person will be interviewed about their experience of using the iCT program (an "exit interview"). Acceptability of the questionnaire battery will be assessed by asking young people to complete an end-of-treatment rating using a 0-100 scale. The young people's parents or carers will also take part in a clinical interview about the young person, will complete a questionnaire pack online, and will be invited to take part in an interview about their experience as a parent or carer of using the iCT program.

N=6 young people will be treated as part of this case series. Young people's and their parents' qualitative feedback on the acceptability of the iCT programme will be reported using data from the exit interviews and from the acceptability rating scales. Averse events during therapy will also be reported. Reliable Clinical Change on a standardised questionnaire of PTSD symptoms (the CPSS-5) will be reported as a preliminary signal of clinical effect. Reliable Clinical Improvement is shown by a reduction of 8 points on the CPSS-5. Acceptability of the outcome measures will be gauged by scrutinising completion rates.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
PTSD symptom scale: Clinician Administered PTSD Scale for Children and Adolescents (CAPS-CA-5, Pynoos et al., 2015)	Clinician Administered. The time period covered is the past month. Items are rated 0-4 based on frequency and severity of symptoms (0=absent, 1= mild, 2=moderate, 3 = severe, 4 = extreme). PTSD diagnostic status is determined by first dichotomizing each symptom as "present" (if the symptom severity is rated 2 or higher) or "absent" (rated 0 or 1). Items pertain to the 4 criterion of PTSD outlined in the DSM-V; criterion B (items 1-5), criterion C (items 6-7), criterion D (items 8-14) and criterion E (items 15-20). PTSD may be diagnosed if the young person has at least one criterion B, one criterion C, two criterion D and two criterion E symptoms and if the disturbance has lasted for more than one month and causes clinically significant distress or functional impairment.

PTSD symptoms: Child Post Traumatic Stress Scale (CPSS-5; Foa et al. 2001)	A self-report questionnaire with 27 items relating to the past one month. The first 20 items evaluate the frequency and severity of PTSD symptoms. Items are rated on a 5-point scale (0= not at all, 1 = <once a week, 2= 2-3 times per week, 3 = 4-5 times a week, 4 = 6 or more times per week). The final 7 items evaluate functional impairment an are scored 1 ('Yes') or 0 ('No') with scores ranging from 0-7, greater scores indicate greater impairment. From the first part of the CPSS scores can range between 0-80 with higher scores indicating greater symptom severity. A score of 31 or higher indicates PTSD.	Baseline
PTSD symptoms: Child Post Traumatic Cognitions Inventory (CPTCI, McKinnon et al 2016)	A self-report questionnaire with 10 items. The CPTCI measures PTSD symptoms since the traumatic event occurred, on a scale of 1-4 (1= don't agree at all, 2 = don't agree a bit, 3 = agree a bit, 4 = agree a lot). Scores range from 0-40 with greater scores indicating greater symptom severity. A total score of 16 or above is considered clinically significant.	Baseline
PTSD symptoms: Children's Revised Impact of Event Scale (CRIES; Perrin et al 2005)	A self-report questionnaire with 8 items (4 measuring intrusions, 4 measuring avoidance).

Avoidance sub-scale is the sum of items 2,4,5 and 8. Scores can range from 0-40 with greater scores indicating greater symptom severity. A total score of 17 or higher indicates PTSD.	Baseline
