Group Treatment for Self-harming Adolescents and Their Parents: a Randomized Controlled Trial (ERA)

17 augustus 2026 bijgewerkt door: Hanna Sahlin, Karolinska Institutet

A Randomised Controlled Trial of Group Emotion Regulation for Adolescent Self-harm (the ERA-study)

Adolescent non-suicidal self-injury (NSSI) is common, strongly associated with psychiatric comorbidity and an increased risk of future suicide attempt. Although interventions targeting emotion regulation have been shown to reduce NSSI in both adults and adolescents few, are available within routine child and adolescent mental health services (CAMHS). Emotion Regulation for Adolescents (ERA), adapted from an evidence-based adult intervention is a brief group-based treatment designed to increase access to effective, evidence-based care for adolescents with NSSI. A large-scale randomised controlled trial (RCT) is needed to establish its efficacy and strengthen the evidence base for emotion regulation interventions for adolescent NSSI.

The overall aim of this project is to increase the availability of evidence-based psychological treatments for adolescent NSSI by developing and evaluating Emotion Regulation for Adolescents (ERA), a novel behavioural and acceptance-based intervention. The main objectives are to establish the efficacy, cost-effectiveness, and long-term outcomes of ERA for adolesent NSSI in two arm RCT comparing ERA with an active control condition (FUNK) as well as to investigate potential mediators such as emotion regulation and self-criticism.

Primary and secondary objectives

Primary objective:

To determine the clinical efficacy of Emotion Regulation group therapy for Adolescents (ERA) in reducing NSSI frequency, as assessed by the clinician-rated Deliberate Self-Harm Inventory, Youth Version (DSHI-Y) in adolescents with NSSI, compared to an active control condition (FUNK). The primary endpoint is 1-month post-treatment.

Secondary objectives:

  1. To determine the efficacy of ERA compared to an active control condition (FUNK) in reducing NSSI severity, increasing NSSI abstinence, reducing impulsive and destructive behaviours, emotion dysregulation and self-criticism anxiety and depressive symptoms; and improving general functioning at 1-month post-treatment.
  2. To evaluate the durability of the treatment effects at 12-month follow-up
  3. To investigate whether improvements in emotion regulation and reductions in self-criticism mediate reductions in NSSI at the primary endpoint (1-month post-treatment).
  4. To conduct a health-economic evaluation of ERA compared with FUNK at 12-month follow-up from the perspectives of the healthcare payer; healthcare system resource use, and society.

Research questions:

  1. Is ERA more efficacious than FUNK in reducing NSSI frequency?
  2. Is ERA more efficacious than FUNK in reducing NSSI severity, increasing NSSI abstinence, reducing impulsive destructive behaviours, emotion dysregulation and self-criticism, anxiety and depressive symptoms; and improving global functioning?
  3. Are the treatment effects of ERA maintained at 12-month follow-up?
  4. Do improvements in emotion regulation and reductions in self-criticism mediate effects on NSSI?
  5. Is ERA more cost-effective than FUNK from healthcare and societal perspectives?

Experimenteel: Emotion Regulation Adolescents (ERA).
Manualized 12-week group intervention for adolescents with NSSI and a parallel five-session parent program.
Gedragsmatig: Emotion Regulation Group Therapy for Self-harming Adolescents, ERA

Manualized 12-week group intervention for adolescents with NSSI and a parallel five-session parent program.

Experimental: ERA Participants receive ERA a 12-week manualized group intervention, targeting NSSI. The intervention focuses on increasing adaptive emotion regulation, reducing impulsive behaviours, and increasing acceptance of difficult emotions with integrated exercises to increase self-compassion and reduce self-criticism.

Caregivers participate in a parallel five-session parent group focusing on preventing NSSI contagion, supporting emotion regulation and strengthening adaptive family communication and functioning.
Actieve vergelijker: Functional habits for mental health (FUNK)
Active comparator: Active Control Condition (FUNK) Manualized psychoeducational group intervention with family participation, individualized safety planning, and weekly risk monitoring.
Gedragsmatig: Functional habits for mental health, FUNK
Active comparator: Active Control Condition (FUNK) Participants receive a manualized active control condition FUNK consisting of: 1) ane individual family session to develop a personalized safety plan; 2) five group-based psychoeducation family sessions over 10 weeks, covering sleep, nutrition and physical activity, anxiety, depression and emotions; and 3) weekly suicide risk monitoring.
