Acceptance and Commitment Therapy-Based Chatbot for Non-suicidal Self-Injury in Adolescents

23 września 2026 zaktualizowane przez: Zhihong Ren, Central China Normal University

Acceptance and Commitment Therapy-Based Chatbot for Non-suicidal Self-Injury in Adolescents: A Randomized Controlled Trial

The purpose of this study is to evaluate the feasibility and effectiveness of a self-guided digital Acceptance and Commitment Therapy (ACT) intervention for adolescents who engage in non-suicidal self-injury (NSSI). The intervention is delivered through a mobile-based program and consists of seven modules focusing on acceptance, cognitive defusion, present-moment awareness, self-as-context, values, and committed action. Adolescents will complete the intervention over a 3-week period and will be randomly assigned to the intervention or control condition. The study will examine whether the digital ACT intervention can reduce NSSI and improve psychological flexibility and other indicators of mental health, including depression, anxiety, hope, and emotion regulation.

Szczegółowy opis

Background: Nonsuicidal self-injury (NSSI) is highly prevalent among adolescents. Acceptance and Commitment Therapy (ACT) has shown promise, but access to traditional therapy is limited. Chatbot-based interventions offer a scalable alternative.

Objective: This randomized controlled trial aims to examine the efficacy of an ACT-based chatbot in reducing NSSI among adolescents.

Methods: Participants will be randomized 1:1 to the intervention group (ACT-based chatbot) or a waitlist control group. The intervention lasts three weeks, with modules covering acceptance, cognitive defusion, values, and committed action. Assessments will be conducted at baseline, post-intervention, 1-month and 3-months follow-up. Primary outcome is the frequency of NSSI episodes. Secondary outcomes include NSSI severity,anxiety symptoms and depressive symptoms.

Analysis: Intention-to-treat analysis will be used. Mixed-effects models will assess changes over time between groups.

The intervention is a fully automated, text-based chatbot delivered via a mobile application or web platform. It is based on the core processes of Acceptance and Commitment Therapy (ACT). Over three weeks, participants will engage with the chatbot for approximately 10 minutes per day, 3 days per week.

The chatbot delivers structured modules covering: (1) acceptance and willingness to experience difficult emotions; (2) cognitive defusion techniques; (3) present-moment awareness; (4) self-as-context; (5) values clarification; and (6) committed action. The chatbot includes safety protocols that provide crisis resources and emergency contact information if participants report severe self-harm urges or suicidal ideation.

The intervention is designed to be self-guided, with no human therapist involvement, to ensure scalability and accessibility.
