About this study

The goal of this clinical trial is to evaluate the effectiveness and safety of Adolescent Self-Injury Intervention Skills Training (ASIST), a treatment program developed by the research team, compared with treatment as usual (TAU) in adolescents who engage in non-suicidal self-injury (NSSI).

The main questions it aims to answer are:

Read more
  1. How do the effectiveness and safety of ASIST compare with those of treatment as usual in adolescents with NSSI?
  2. How are treatment-related changes in psychological, clinical, behavioral, and biological measures associated with treatment response?
  3. Can machine learning techniques be used to predict treatment responses in adolescents with NSSI?

Researchers will compare adolescents receiving ASIST with those receiving TAU to examine changes in psychological, clinical, and behavioral characteristics before and after treatment. They will also examine changes in cortisol and beta-endorphin levels, as well as brain activity and functional connectivity during task performance, to explore potential mechanisms associated with treatment response.

Participants will:

  1. Receive either ASIST or TAU.
  2. Complete psychological, clinical, and behavioral assessments before and after treatment.
  3. Undergo measurements of cortisol and beta-endorphin levels.
  4. Complete tasks during brain imaging assessments to measure brain activity and functional connectivity.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Adolescent Self-Injury Intervention Skills Training (ASIST)Behavioural

    ASIST is a structured psychological intervention developed for adolescents who engage in non-suicidal self-injury. The program consists of four sessions delivered over four weeks, focusing on: (1) understanding self-injury, behavioral chain analysis, and safety planning; (2) identifying and modifying automatic thoughts, core beliefs, and rumination; (3) improving emotional awareness, expression, and regulation; and (4) developing stress management, coping, and interpersonal communication skills. The intervention incorporates cognitive behavioral and emotion regulation strategies. Participants with persistent clinically significant difficulties at the four-week follow-up may receive two additional sessions addressing cognitive and interpretation biases and difficulties identifying and expressing emotions.

  • Treatment as Usual (TAU)Behavioural

    Participants assigned to the TAU group will receive routine clinical care for non-suicidal self-injurious behavior over a 4-week period. Depending on their individual clinical needs, treatment may include psychoeducation, safety planning, behavioral chain analysis, counseling, and supportive psychotherapy, consistent with usual care practices in child and adolescent psychiatry.

Study groupRoleWhat they receive
Adolescent Self-Injury Intervention Skills Training (ASIST)ExperimentalParticipants assigned to this arm will receive Adolescent Self-Injury Intervention Skills Training (ASIST), a structured psychological intervention developed for adolescents who engage in non-suicidal self-injury. The program consists of four sessions delivered over four weeks and incorporates cognitive behavioral therapy, emotion regulation, stress coping skills, and interpersonal skills training. The sessions focus on understanding self-injury and developing safety plans, identifying and modifying negative automatic thoughts, improving emotional awareness and regulation, and developing adaptive stress coping strategies. Participants who continue to demonstrate clinically significant difficulties at the four-week follow-up assessment may receive two additional advanced sessions targeting cognitive biases and difficulties identifying and expressing emotions.
Receives: Behavioral: Adolescent Self-Injury Intervention Skills Training (ASIST)
Treatment as Usual (TAU)Active comparatorParticipants assigned to this arm will receive treatment as usual (TAU) for non-suicidal self-injury over four weeks. Treatment will consist of routine clinical interventions typically provided to adolescents presenting with self-injurious behaviors in child and adolescent psychiatric settings, including psychoeducation on self-injury prevention, safety planning, behavioral chain analysis, counseling, and supportive psychotherapy. Participants will undergo the same baseline, post-treatment, and four-week follow-up assessments as those in the ASIST group.
Receives: Behavioral: Treatment as Usual (TAU)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Self-Harming Behaviors as Assessed by the Self-Harm Inventory (SHI)

    Self-harming behaviors will be assessed using the Korean version of the Self-Harm Inventory (SHI), a 20-item self-report questionnaire evaluating the frequency of self-harming and self-destructive behaviors. Participants rate each item based on their experiences over the past 4 weeks or their current experiences, using a 4-point Likert scale ranging from 1 (almost never) to 4 (always). Total scores range from 20 to 80, with higher scores indicating more frequent or severe self-harming behaviors. Changes in total SHI scores will be evaluated from baseline (V1) to post-intervention (V5) and from baseline (V1) to the 4-week follow-up (V6).

    Measured: Baseline (V1, Week 1), Post-intervention (V5, Weeks 4-5), and 4-week Follow-up (V6, Weeks 8-9)

Secondary outcomes (6)
  1. Change in Frequency of Non-Suicidal Self-Injury as Assessed by the Korean Inventory of Statements About Self-Injury (K-ISAS)

    The functions of non-suicidal self-injury (NSSI) will be assessed using the K-ISAS, a self-report questionnaire evaluating NSSI behaviors and their underlying functions. The assessment of NSSI functions consists of 39 items measuring 13 functions of NSSI, categorized into intrapersonal and interpersonal functions. Each item is rated on a 3-point Likert scale ranging from 0 (not relevant) to 2 (very relevant), yielding a total score ranging from 0 to 78. Higher scores indicate greater endorsement of NSSI functions. Changes in total scores will be evaluated from baseline (V1) to post-intervention (V5) and from baseline (V1) to the 4-week follow-up (V6).

    Measured: Baseline (V1, Week 1), Post-intervention (V5, Weeks 4-5), and 4-week Follow-up (V6, Weeks 8-9)

  2. Change in Severity of Suicidal Ideation as Assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS)

    Suicidal ideation severity will be assessed using the C-SSRS, assessing suicidal ideation and behavior. Suicidal ideation severity is evaluated using five yes/no items and scored on a scale from 0 (no suicidal ideation) to 5 (active suicidal ideation with a specific plan and intent). Higher scores indicate greater severity of suicidal ideation. A suicidal ideation severity score of 4 or higher will be used as the cutoff for elevated suicide risk in this study. Changes in suicidal ideation severity scores will be evaluated from baseline (V1) to post-intervention (V5) and from baseline (V1) to the 4-week follow-up (V6).

    Measured: Baseline (V1, Week 1), Post-intervention (V5, Weeks 4-5), and 4-week Follow-up (V6, Weeks 8-9)

  3. Change in Emotion Regulation Difficulties as Assessed by the Difficulties in Emotion Regulation Scale-16 (DERS-16)

    DERS-16 is a 16-item self-report questionnaire designed to assess difficulties in emotion regulation across five domains: nonacceptance of emotional responses, difficulties engaging in goal-directed behavior, impulse control difficulties, limited access to emotion regulation strategies, and lack of emotional clarity. Each item is rated on a 5-point Likert scale ranging from 0 (almost never) to 5 (almost always), yielding a total score ranging from 16 to 80. Higher scores indicate greater difficulties in emotion regulation. Changes in total DERS-16 scores will be evaluated from baseline (V1) to post-intervention (V5) and from baseline (V1) to the 4-week follow-up (V6).

    Measured: Baseline (V1, Week 1), Post-intervention (V5, Weeks 4-5), and 4-week Follow-up (V6, Weeks 8-9)

  4. Change in Impulsivity as Assessed by the Barratt Impulsiveness Scale-Brief (BIS-Brief)

    The BIS-Brief is an 8-item self-report questionnaire designed to assess impulsivity as a unidimensional construct. Each item is rated on a 4-point Likert scale ranging from 0 (never) to 3 (almost always), yielding a total score ranging from 0 to 24. Higher scores indicate greater impulsivity. Changes in total BIS-Brief scores will be evaluated from baseline (V1) to post-intervention (V5) and from baseline (V1) to the 4-week follow-up (V6).

    Measured: Baseline (V1, Week 1), Post-intervention (V5, Weeks 4-5), and 4-week Follow-up (V6, Weeks 8-9)

  5. Change in Depressive Symptom Severity as Assessed by the Children's Depression Rating Scale-Revised (CDRS-R)

    The CDRS-R is a 17-item clinician-rated scale to measure the severity of depression of children and adolescents. The scale evaluates emotional, cognitive, behavioral, and somatic symptoms associated with depression. Depression symptoms are rated on a 5-point scale from 1 to 5 for sleep, appetite, and tempo of speech items and a 7-point scale from 1 to 7 for remaining 14 items. Total scores range from 17 (normal) to 113 (severe depression), with higher scores indicating greater severity of depressive symptoms. Changes in total CDRS-R scores will be evaluated from baseline (V1) to post-intervention (V5) and from baseline (V1) to the 4-week follow-up (V6).

    Measured: Baseline (V1, Week 1), Post-intervention (V5, Weeks 4-5), and 4-week Follow-up (V6, Weeks 8-9)

  6. Change in Anxiety Symptoms as Assessed by the Screen for Child Anxiety Related Emotional Disorders (SCARED)

    The SCARED is a 41-item questionnaire designed to assess anxiety symptoms in children and adolescents across five domains: panic/somatic symptoms, generalized anxiety, separation anxiety, social anxiety, and school avoidance. Each item is rated on a 3-point Likert scale ranging from 0 (not true or hardly ever true) to 2 (very true or often true), yielding a total score ranging from 0 to 82. Higher scores indicate greater severity of anxiety symptoms. A total score of 25 or higher suggests the possible presence of an anxiety disorder, while a score of 30 or higher indicates increased likelihood of an anxiety disorder. Changes in total SCARED scores will be evaluated from baseline (V1) to post-intervention (V5) and from baseline (V1) to the 4-week follow-up (V6).

    Measured: Baseline (V1, Week 1), Post-intervention (V5, Weeks 4-5), and 4-week Follow-up (V6, Weeks 8-9)
