Child-On-Child Sexual Abuse and it’s Impact on Mental Health

The topic of child-on-child sexual abuse (COCSA) can be a challenging one to approach. The idea that non-consensual sexual activity can happen between children can be difficult to comprehend.  However, ongoing silence and misunderstanding surrounding the issue can be both damaging and dangerous. 

When a child is sexually abused by another child, it can impact their emotional development, self-perception, and relationships. Often, survivors of child sexual abuse experience such impacts for years, and sometimes a lifetime. Without proper intervention, sexually abusive behavior can cause emotional wounds that deepen rather than heal. 

Early, compassionate support can make a difference. While healing from COCSA is not a straightforward path, education, trauma-informed resources, and understanding caregivers may support children in their recovery. This article examines the impacts of child-on-child sexual abuse and the importance of early intervention. It also discusses what prevention in homes, schools, and community spaces can look like and possible pathways to healing.

COCSA meaning: Understanding child-on-child sexual abuse

According to the advocacy group RAINN (Rape, Abuse, and Incest National Network), the term COCSA refers to “situations where one minor engages in sexually abusive behavior toward another minor.” These behaviors are inappropriate, non-consensual, and often coercive or manipulative—such as making a child undress and engaging them in inappropriate activities or exposing them to pornographic materials.

Often, survivors of child sexual abuse experience mistreatment from siblings, classmates, or neighborhood peers. Many incidents occur in seemingly safe environments where children are assumed to be supervised or safe due to proximity to family or familiar people.

Since cases of COCSA mean that both the individual who was harmed and the one who caused harm are children, addressing these situations can be very complex. Every case demands a thoughtful, trauma-informed approach—for both the child who has been targeted and the child who engaged in the harmful behavior.

Distinguishing between curiosity and sexually abusive behavior

Sexual curiosity is a common part of development in childhood and adolescence. However, when a minor engages in non-consensual sexual acts using aggression or coercion, it may be considered sexual abuse. The National Center on the Sexual Behavior of Youth (NCSBY) offers a guide for parents and caregivers with information on the differences between typical and abusive sexual behavior by age. 

What causes child-on-child sexual abuse?

Understanding possible root causes of child-on-child sexual abuse may help caregivers and professionals engage in effective prevention efforts. Research suggests that, in many cases, this behavior arises due to factors like exposure and vulnerability. 

Some factors that can contribute to a child enacting this type of abuse may include:

• Exposure to sexual material through media or unsupervised internet use
• Living in a household where sexual abuse, violent behaviour, or physical abuse is present
• Replication of behaviors the child has witnessed or experienced
• Lack of emotional guidance or boundaries at home
• Neglect, especially emotional neglect, which can lead to unmet needs and confusion around intimacy

A child might not even recognize the harm they’re causing—but the trauma for the one being abused is real, regardless of whether the other child understands the gravity of their actions.

Sibling sexual abuse

Sibling sexual abuse is the most common form of child-on-child sexual abuse. One older UK study reports that 43% of young adults who had been sexually abused identified a sibling as the perpetrator.

This type of abuse often happens in secrecy and can involve more frequent and prolonged incidents than abuse by adults. It may include more invasive acts and often targets younger children. Because siblings are typically close in age, the abuse is sometimes mistaken for curiosity or “games,” especially when adults in the home dismiss or overlook it.

A young person who is abused by a sibling is also less likely to speak up about the abuse. Feelings of shame, fear of disrupting the family, or being disbelieved often prevent them from saying something. Some are even pressured by parents, caregivers, or other family members to retract their report of the abuse and/or continue contact with the sibling who harmed them to avoid “family disruption” or interaction with agencies like Child Protective Services.

Additionally, sibling abuse may not always register as distressing to the child at the time, especially if they’ve been led to believe it’s normal. In many cases, the emotional impact surfaces later in life, sometimes only after reaching adulthood. 

How power and coercion factor into COCSA

Though not always, COCSA sometimes occurs when a power difference exists among children due to factors such as age, physical development, authority roles, and social status. There are several forms of coercion and control, including:

• Physical or emotional coercion
• Manipulation
• Threats and aggression
• Pressure
• Exploiting vulnerabilities 

Understanding consent and non-consensual sexual activity among minors 

Children are often considered among the most vulnerable to sexual abuse, including COCSA, as they’re exposed to many factors that can hinder their ability to understand they’re being abused. For example, sometimes abusers “normalize” the sexual activity if the abuse is introduced gradually or the child has no basis for what constitutes “normal” behavior.  

Some abusers exploit childhood innocence, manipulating the target of their abuse so they believe it is their fault or that they enjoyed the attention. Manipulation may also include emotional attachment and fear when the child loves or trusts the abuser, or fears the consequences of reporting. Younger children may have developmental limitations in cognitive maturity or verbal skills that affect their ability to understand and communicate what’s happening.    

Misconceptions about COCSA

Myths about child-on-child sexual abuse often downplay its severity or wrongly blame child survivors. For example, some misidentify sexual abuse between two children as being curious or a “phase.” Some believe that only older children or children with behavioral issues abuse others. There is also a belief among some adults that it’s easy to tell when a minor engages in or is a recipient of sexual abuse. The reality is, like other forms of abuse, COCSA is often hidden and may not display obvious signs.  

Warning signs of child-on-child sexual abuse

Adults often miss or misinterpret these signs, especially if the child doesn’t or can’t talk about what happened. It’s one reason why creating environments where children are believed and supported when they express discomfort can be essential for prevention or swift interventions. 

How early abuse can impact mental health

When abuse occurs, especially in one’s early years, survivors may carry invisible burdens into adolescence and adulthood, ranging from chronic anxiety to distrust of intimacy and beyond. Children who have experienced COCSA may carry shame, guilt, confusion, and conflicting emotions into adulthood. These and other symptoms of lifelong trauma can present unique challenges in daily life, as well as contribute to co-occurring mental health issues like anxiety, depression, PTSD, and obsessive-compulsive disorder (OCD). Some children exposed to COCSA may experience feelings of unworthiness, often internalized from the abuse, that can lead to self-harm or suicidal ideation.  

On children who perpetrate COCSA

Many children who harm other children have themselves been hurt. While this doesn’t excuse the behavior, it can provide context and explain why punishment may not help if the underlying issues aren’t addressed.

Children acting out harmful sexual behaviour often do so out of confusion, exposure, or trauma. While boundaries must be reinforced, these young individuals typically also require psychological intervention. Supporting both the survivor and the child who caused harm may help interrupt harmful patterns and promote healing.

Understanding cycles of sexual abuse

Children who are not offered healing pathways after being sexually abused may reenact behaviors they don’t fully understand, sometimes seeking control or mimicry of past experiences.

Breaking that cycle often involves:

• Acknowledging the trauma without shame
• Providing age-appropriate therapy and accountability
• Teaching empathy and healthy relationship skills
• Offering safety and connection rather than alienation

How COCSA can affect development and relationships

Childhood trauma, especially from sexual violence, can not only result in a loss of childhood innocence, but it also often interferes with cognitive, physical, and social growth. Many children impacted by COCSA face emotional, social, and academic challenges, such as: 

• Trouble focusing, memory lapses, or slower learning
• Avoidance of peer interaction or group activities
• Lack of confidence in their own thoughts or needs
• Delays in emotional maturity or inappropriate sexual behavior
• Difficulty developing a clear, stable identity
• Delays in physical development

If left unaddressed, these may follow them into adulthood, potentially affecting relationships, career and financial stability, self-esteem, and overall well-being. 

Impacts on trust, safety, and relationships later in life

Children who’ve been exposed to sexual abuse often experience trust issues, even with supportive, once-trusted adults. They may isolate from peers, teachers, family, and friends for fear of being hurt. Later in life, some face unique challenges with attachment in intimate relationships that may create barriers to a healthy, loving connection.    

Early intervention and child sexual abuse prevention

While it’s not always possible to prevent child sexual abuse or other harm, early intervention and thoughtful prevention efforts may significantly reduce risk. Educating children in simple, clear, age-appropriate language about boundaries and body autonomy can lay the groundwork for safety and self-advocacy. Some other examples of preventative measures may include:

• Talking early and often about how to say no
• Teaching consent as part of adolescent health education
• Ensuring trusted adults, such as caregivers and teachers, know how to spot red flags of child sexual abuse
• Integrating comprehensive prevention programs in schools
• Creating environments where secrets are not encouraged or rewarded
• Seeking assistance and appropriate care at the first sign of concern rather than after harm has been done

Healing after childhood sexual abuse

The first step an adult can take to help a child experiencing sexual abuse is to respond with care and belief rather than minimize harm. Healing from COCSA is not typically linear. Children may revisit their pain at different stages in life, but with support, they may be able to continue moving forward toward healing. Some factors that may help promote recovery include:

• Providing nonjudgmental spaces to speak freely
• Believing the child, even when the story is painful or confusing
• Surrounding them with emotionally attuned caregivers
• Seeking out trauma-informed therapy on their behalf that meets them where they are
• Reinforcing that what happened to them was not their fault

How therapy can help

Seeking therapy for a child who has been abused can be paramount to supporting their emotional well-being going forward. It can also be recommended for adults who experienced abuse in their past, or for a parent or caregiver whose child has experienced sexual abuse. A COCSA therapist can help an individual unpack their experiences and related emotions in a safe, nonjudgmental environment and receive compassionate support as they move forward on their healing journey. An experienced COCSA therapist may also provide a referral to a sex therapist for those adults who are looking to reclaim their body and their sense of sexual pleasure. 

Evidence-based trauma-informed therapies include:

• Cognitive behavioral therapy (CBT)
• Cognitive processing therapy
• Eye movement desensitization and reprocessing
• Narrative exposure therapy
• Prolonged exposure therapy

Such methodologies can be tailored for developmentally appropriate care and may be supplemented with complementary approaches like art, music, nature, and movement therapies. Adults and children may also benefit from survivor support groups and community programs. Advocacy organizations like bravemovement.org can connect individuals with peer resources and support as well as offer crisis assistance.

Exploring the option of online therapy

Online therapy—which allows you to connect with a licensed therapist remotely, from anywhere you have an internet connection—can be a more comfortable way for some people to discuss challenging topics, such as child sexual abuse experience and past trauma. With a platform like BetterHelp, you can get matched with a therapist based on your needs and preferences, and you can switch providers at any time for no additional cost. This can help you find someone you feel comfortable working with on the path toward healing. While it may not be appropriate care for younger individuals or those experiencing more severe mental health issues, online therapy can be an excellent alternative to conventional in-person treatment.  

More research is required regarding the effectiveness of online therapy for treating COCSA survivors in particular. However, studies have suggested that online care can often be effective for treating depression, anxiety, and other symptoms related to trauma and PTSD.
