Effective psychosocial therapies treat self-injurious thoughts and behaviors in youth

Over the past two decades, research on psychosocial treatments for self-injurious thoughts and behaviors (SITBs) in youth has grown substantially. Clinicians and families now have more options than ever before, including therapies designed specifically to reduce suicidal ideation, suicide attempts, and nonsuicidal self-injury. Still, the field continues to ask an important question: which treatments have the strongest evidence, and for whom do they work best? As rates of youth suicide and self-harm remain elevated, regularly updating the evidence base is essential to ensure that prevention and intervention efforts are grounded in the most rigorous and current science.

With an updated review covering studies published between 2018 and 2024, Dr. Catherine Glenn and her team evaluated the strength of evidence for psychosocial treatments targeting self-injurious thoughts and behaviors in children and adolescents. Building on prior evidence reviews, she examined randomized controlled trials and other rigorous evaluations to determine which approaches meet criteria for well-established, probably efficacious, or possibly efficacious treatments. The findings indicate that several structured, skills-based therapies, particularly those incorporating cognitive behavioral and dialectical behavior therapy components, continue to show the strongest support for reducing suicidal behaviors and self-harm in youth. Family involvement and emotion regulation skill-building emerged as common and important elements across effective interventions. At the same time, the review highlighted ongoing gaps, including limited replication studies, variability in outcome measurement, and the need for more research in diverse populations and real-world clinical settings. Overall, evidence-based psychosocial treatments can meaningfully reduce risk for self-injurious thoughts and behaviors in youth, while underscoring the importance of continued refinement and implementation research.

Adolescent crisis line volunteers were affected by the experience providing peer support

Crisis lines play a vital role in suicide prevention, offering immediate support to individuals in distress. Teen-to-teen (t2t) crisis lines, where adolescent volunteers provide peer support, have emerged as a promising resource, particularly given that young people are often more comfortable confiding in peers than adults. While extensive research has examined the effectiveness of adult-staffed crisis lines, little is known about the experiences of youth volunteers who take on this emotionally demanding role. Understanding how these adolescents are affected – both positively and negatively – by their work is crucial for ensuring their well-being and improving the sustainability of t2t crisis services.

Dr. Catherine Glenn’s AFSP-funded pilot study examined the experiences of 20 t2t crisis line volunteers, ages 14–20, from two of the largest programs in the United States. Volunteers reported a strong motivation to help others and a sense of fulfillment from their work, citing benefits such as improved communication skills, greater empathy, and increased confidence. However, some also reported challenges, including emotional exhaustion and feeling pressure to support others. Notably, 90% of volunteers had handled high-risk suicide-related contacts, underscoring the intensity of their work. While most participants described their experience as overwhelmingly positive, the findings highlight the importance of providing structured support to safeguard the mental health of youth crisis responders. Further research is needed to explore the long-term impact of t2t crisis line work and optimize training and supervision practices.

Inside the Research

Crisis lines are one of the oldest suicide prevention approaches in the U.S. and are viewed as a national “safety net” during a mental health crisis. Teen-to-teen (t2t) crisis lines are a special type of crisis service where youth volunteers help their peers. This project is the first to examine the impact of t2t crisis line work for youth volunteers in collaboration with two of the largest t2t lines in the U.S.: Teen Line and Youth Line.

Full scientific abstract

Suicide is the 2nd leading cause of death among adolescents in the U.S., and, alarmingly, suicide rates have increased significantly in this age group over the past decade. Effective suicide prevention for youth requires a comprehensive approach incorporating a range of upstream and downstream strategies. Crisis hotlines are one of the oldest downstream approaches in the U.S. "viewed as a national "safety net," providing essential support and resources during a suicidal crisis. Nearly two decades of research have supported the effectiveness of adult-run crisis hotlines for adults. Teen-to-teen (t2t) crisis lines are a specific type of crisis service in which youth volunteers help their similarly aged peers (through texts, chats, calls, and emails). Although t2t lines have the potential to offer a unique experience both for the youth who utilize the lines and the youth volunteers who staff them, there have been longstanding concerns about, and limited evidence to support, the safety and impact of these t2t lines for youth. To first address this crucial gap, this project will examine the impact, and critically the safety, of t2t crisis lines for youth volunteers. Notably, before we examine the effectiveness of t2t lines, we need to know if it is safe for youth to do this work. Youth volunteers may benefit from the t2t experience (e.g., helping peers), but there also is potential for this experience to be negative or harmful (e.g., increasing suicide risk). Research to date (all with adults) examining the impact of crisis line work on staff/volunteers has been mixed" some studies have observed a positive impact and others a negative one. It is essential to examine the impact on youth volunteers specifically, as young people may be particularly vulnerable to the stress of crisis line work. The proposed project will be the first to examine the impact of t2t crisis line work for youth volunteers (14-20 years-old) in collaboration with two of the largest t2t lines in the U.S." Teen Line (Los Angeles, CA, receives over 21,000 contacts/year) and Youth Line (Portland, OR, receives over 28,000 contacts/year). The aims of the project are: (1) to examine the negative impact, and specifically the safety, of t2t line volunteerism on youth volunteers, (2) to examine the positive impact of t2t crisis line volunteerism on youth volunteers, and (3) to examine volunteer (e.g., lived experience with mental health conditions) and crisis line factors (e.g., supervisor support) that may impact volunteers' experience on the t2t crisis line. This research is in line with several national funding priorities, including AFSP's new priority area to evaluate technological tools for suicide prevention, the National Action Alliance for Suicide Prevention's priority to examine "What services are most effective for treating the suicidal person and preventing suicidal behavior?", and the National Institute of Mental Health's special interest in suicide prevention crisis services. If t2t volunteerism is found to be safe and beneficial for youth, the next step in this research will be to examine the effectiveness of t2t crisis lines for youth who utilize these services.
