Effects of Internet-based ERITA Added to TAU in Young People With Non-Suicidal Self-Injury (TEENS) Feasibility Trial

Treatment Effects of Internet-based Emotion Regulation Individual Therapy for Adolescents (ERITA) Added to Treatment as Usual in Young People With Non-Suicidal Self-Injury - (TEENS) Feasibility Trial

There has been a significant increase in non-suicidal self-injury the last decades especially among young people and treatment initiative are sparse. We aim to assess the feasibility of methods, procedures, and safety of internet-based Emotion Regulation Individual Therapy for Adolescents (ERITA) as add on to treatment as usual (TAU) in 13-17-year-old patients with non-suicidal self-injury referred to psychiatric services.

Non-suicidal self-injury has disseminated almost epidemically through the last decades in young persons. There is no evidence of any experimental treatment for non-suicidal self-injury in adolescents, superior to treatment as usual. Patients with stigmatizing illness such as non-suicidal self-injury may find internet-based interventions more acceptable. The study is a feasibility trial, with a randomization procedure in a parallel group design. Patients will be recruited from Child- and Adolescent Mental Health Services (age 13 to 17 years). The experimental intervention is internet-based, and therapist guided; ERITA consists of online Emotion Regulation Individual Therapy for Adolescents (ERITA) as add-on to treatment as usual. Treatment as usual is provided by multidisciplinary teams in nine outpatient clinics within Child and Adolescent Mental Health Services in the Capital Region of Denmark. Feasibility of recruitment and trial procedures will be monitored as well as explorative clinical outcomes.

Single-center, feasibility trial including a randomization procedure in a parallel group design with blinded outcome assessment.

Due to the nature of the intervention, a blinding of participants and therapists (intervention providers) is not possible. Blinded outcome assessment and data management will be performed. Statistical analyses will be performed by two blinded statisticians presenting independent reports. Based on the two blinded conclusions, two abstracts will be written and published (on a website).

ERITA is a youth-adapted version of Emotion Regulation Group Therapy (ERGT), based on cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and Acceptance and Commitment Therapy (ACT), which encounters emotional recognition and regulation, crisis strategies and skills training. The ERITA intervention is provided as add-on to TAU and consists of 12 weeks, manualized, therapist guided internet-based therapy. The intervention also provides six modules for the parents focusing on NSSI and other risk-taking behaviors, emotional awareness, and validation skills. The participants must complete one module every week while the parents must complete a module every second week. A mobile app is available to complement the online treatment. The app includes reminders of homework and skills and allows to report on both self-destructive behaviors and impulses daily.

Child and Adolescent Mental Health Services (CAMHS) offer specialized treatment for children and adolescents. TAU encounters a variety of clinical treatment and assessment offers, representing a highly inhomogeneous group of treatments, for instance: Pharmacological treatment, Family-Based Treatment (FBT), Cognitive Behavioral Therapy, supportive counselling and psychoeducation. Throughout the trial course the treatment responsibility is handled by clinicians providing TAU.

Completion of follow-up will be defined as completing at least one clinical outcome (non-suicidal self-injury events) at end of intervention. If the number participants with completed outcomes is 26 out of 30, the fraction will be 87%, 95% CI 75% to 99%. A follow-up fraction of 87% or more will be acceptable for a future trial while a fraction below 75% will impose serious problems of interpreting the trial result in a future large pragmatic trial.

We will determine the fraction of potential participants as the number of eligible persons compared to the number of randomized persons. If the number of participants randomized out of the number of eligible persons is 30 out of 75, the fraction will be 40%, 95% confidence interval (CI) will be: 29% to 51%. A randomization fraction of 29% or more will be acceptable for a future trial, while a fraction below 29% will impose serious problems of recruitment for a future large pragmatic trial.

Compliance with the experimental intervention will be defined as completing at least six of 12 ERITA sessions. ERITA will automatically register time for login and save the exercises that have been completed. If the number of compliant experimental participants is 11 out of 15, the fraction will be 73%, 95% CI 51% to 96%. A compliance fraction of 51% or more will be acceptable for a future trial while a fraction below 51% will impose serious problems of interpreting the trial result in a future large pragmatic trial.

Non-suicidal self-injury, assessed at baseline and end of therapy (12 weeks) by blinded outcome assessment by phone with Deliberate Self-Harm Inventory (DSHI-Y)

Quality of life at 12 weeks, assessed with Kidscreen-10. 5-point Likert scale, range: not at all, a little, modearte, much, very much.

Symptoms of depression, anxiety and stress at 12 weeks, assessed with Depression Anxiety Stress Scale (DASS-21). 4-point Likert scale, range: did not apply to me, applied to me to some degree, applied to me to a considerable degree, applied to me much/most of the time. Totale range for subscores: 0-42. Higher scores reflects worse outcome.

Difficulties in emotion regulation, assessed weekly during 12 weeks with Difficulties in Emotion Regulation Scale (DERS-16). 5-point Likert scale, range: almost never, some times, half of the time, most of the time, all the time. Total scores range from 16 to 80, with higher scores reflecting grater levels of emotion dysregulation.

Indirect self-destructive behaviours at 12 weeks, assessed with Borderline Symptom List (BSL-supplement). 5-point Likert scale, range: not at all, once, 2-3 times, 4-6 times, daily or more often. Total scores range from 0-44 and higher scores reflect worse outcome.

Suicidal ideations, plans and actions at 12 weeks, assessed with Columbia (C-SSRS). Dichotomous outcome yes/no; if yes intensity is rated on a 5-point Likert scale, total score range: 2-25. Higher scores reflect worse outcome.

Adolescent's perception of Parents' ability to cope with children's negative emotions at 6 weeks and 12 weeks, assessed with The Coping with Children's Negative Emotions Scale (CCNES-APP). 7-point Likert scale, Range from very unlikely to very likely. Six Sub scales with total score range: 0-42. The sub scale are inversely related.

Parents' perceived ability to cope with children's negative emotions at 6 weeks and 12 weeks, assessed with The Coping with Children's Negative Emotions Scale Adolescent (CCNES-A). 7-point Likert scale, Range from very unlikely to very likely. Six Sub scales with total score range: 0-42. The sub scale are inversely related.
