Internet Delivered ERITA for Nonsuicidal Self-Injury

Not Applicable

Completed

• Conditions: Nonsuicidal Self-injury
• Interventions: Behavioral: Treatment as usual; Behavioral: Emotion regulation individual therapy

• Registration Number: NCT03353961
• Lead Sponsor: Karolinska Institutet

Brief Summary

To evaluate if Internet delivered emotion regulation individual therapy for adolescents is an efficacious treatment when delivered as adjunctive to treatment as usual compared to a control group consisting of treatment as usual.

Detailed Description

Statistical Analyses

Treatment effects will be evaluated according to the intention-to-treat principle. Primary end-point for all outcomes is post-treatment. Secondary end-point include a controlled 3 month follow-up.

Primary Analysis

The primary outcome analysis will include treatment group (ERITA , TAU) and weekly reports of NSSI frequency measured once every week 4 weeks prior to treatment start, once every week during treatment, and once every week four weeks after treatment termination. Regression analysis modelled for count data will be used to estimate trend over time. Four weeks after treatment termination will be considered primary endpoint. Pairwise contrasts (group x time interaction) from the regression model will be used to evaluate between-group differences at primary endpoint (4 weeks after treatment termination).

Secondary Analyses

Secondary outcomes measured once before, during, and after treatment will be analyzed in a similar fashion as for the primary outcome, modelled after data's distribution (count or continuous). Measures collected only once at baseline and post-treatment will be analyzed with regression analyses including treatment group (online ERITA , TAU) as the between-subjects factor, time (baseline to post) as the within-subjects factor, and group × time interactions, modelled after data's distribution (count or continuous).

Parallel process latent growth curve modeling will be used to determine whether change in week-to-week emotion dysregulation (DERS-16) during treatment mediate the overall effect of ERITA+ETAU on week-to-week change in the primary outcome self-rated NSSI frequency (DSHI-Y).

3 Month Follow-Up

Data collected at 3-month follow-up will be used to determine the extent to which potential treatment gains were maintained both within and between treatment conditions

Update 28 April 2022: As a secondary analyses, we also aim to investigate the effect of treatment moderators (primary aim) and predictors (secondary aim) on NSSI frequency one month after treatment termination. This update was submitted prior to conducting the analyses.

The selection of potential moderators was theoretically and empirically motivated. We will investigate the following variables (measured at baseline):

Age Difficulties in emotion regulation As measured with the Difficulties in Emotion Regulation Scale - 36 item version (DERS) Past month NSSI frequency As measured with the Deliberate Self-Harm Inventory Youth version (DSHI-Y) Global functioning As measured with the Childrens Global Assessment Scale Depressive symptoms As measured with the 21-item Depression Anxiety Stress Scales (DASS-21) Sleep difficulties As measured with the Insomnia Severity Index (ISI) Parental Minimization - discounting or devaluing the child's negative emotions/problems As measured with The Coping with Children's Negative Emotions Scale Adolescent Version (CCNES-A), subscale minimazation Level of suicidality As measured with the MINI-KID International Neuropsychiatric Interview, version 6

Arm && Interventions

Group	Intervention	Description
Treatment as usual	Treatment as usual	Participants will receive treatment as usual for 11 weeks of treatment as usual as provided in the community.
Adjunctive Internet-delivered ERITA	Emotion regulation individual therapy	Participants will receive 11 weeks of internet-delivered emotion regulation individual therapy with therapist support adjunctive to treatment as usual as provided in the community. The caregiver(s) will receive 6 modules of internet-delivered parent program with therapist support.

Primary Outcome Measures

Name	Time	Method
Deliberate Self-Harm Inventory Youth version (DSHI-Y)	Change from baseline, once every week during treatment (0-12 weeks after baseline), 3 and 12 months after treatment has ended	Frequency of nonsuicidal self-injury

Secondary Outcome Measures

Name	Time	Method
Difficulties in Emotion Regulation Scale - 16 item version (DERS-16)	Change from baseline, once every week during treatment (0-12 weeks after baseline), 3 and 12 months after treatment has ended	Difficulties in emotion regulation as primary potential mechanism of change. Ranges from 16-80, with higher scores indicating more difficulties.
the 21-item Depression Anxiety Stress Scales (DASS-21)	Change from baseline, 12 weeks after treatment starts, 3 and 12 months after treatment has ended	Symptoms of depression, anxiety and stress. Each subscale (depression, anxiety and stress) ranges from 0-21, with higher scores indicating more symptoms.
Borderline Symptom List Supplement	Change from baseline, once every week during treatment (0-12 weeks after baseline), 3 and 12 months after treatment has ended	Impulsive self-destructive behaviors
Difficulties in Emotion Regulation Scale - 36 item version (DERS)	Change from baseline, 12 weeks after treatment starts, 3 and 12 months after treatment has ended	Difficulties in emotion regulation. Ranges from 36-180, with higher scores indicating more difficulties.
Childrens Global Assessment Scale	Change from baseline, 16 weeks after treatment starts, 3 months after treatment has ended	Global functioning. Ranges from 1-100, with higher scores indicating better functioning.
Acceptance and Action Questionnaire	Change from baseline, 12 weeks after treatment starts, 3 and 12 months after treatment has ended	Acceptance and valued actions. Ranges from 7-49, with higher scores indicating less acceptance and valued actions.
The Clinical Global Impressions -Severity and Improvement scales	Change from baseline, 16 weeks after treatment starts, 3 months after treatment has ended	Global symptom severity and improvement. Severity of illness scale ranges from 1-7, with higher scores indicating higher severity of illness. Global improvement scale ranges from 1-7 with lower scores indicating more improvement.
