Childhood Sexual Abuse: A Mental Health Issue


Author: Canadian Mental Health Association, BC Division


Our experiences in childhood play a big part in shaping our health and well-being throughout our lives. Sexual abuse in childhood can leave scars that can last for a long time. But many cases are never reported.

Some people feel very scared about reporting abuse. They may feel embarrassed, guilty or ashamed. Some people blame themselves or believe that they deserved to be abused. Others report abuse, but they aren’t taken seriously or believed. Sexual abuse is a crime. It can have a large impact on health and well-being.

What is it?

Sexual abuse is any sexual contact between a child and an adult, or using a child for sexual purposes. It's often done by someone the child knows and trusts. In BC, a child is anyone under the age of 19.1 Sexual exploitation is another form of child sexual abuse. It happens when a child is talked into or forced into sex acts in exchange for things like money, drugs, food or shelter.2


Who does it affect?

It’s estimated that one in three girls and one in six boys are sexually abused in North America.3 The exact number is hard to determine because many cases are not reported to authorities.4 Of adults who receive mental health services, it’s thought that as many as 50% of women and 25% of men have experienced childhood sexual abuse.5

Children living with a mental illness, learning disability or physical disability are more than twice as likely to report childhood sexual abuse as their peers. These health problems may also make it harder to identify mental health problems, like post-traumatic stress disorder, that are linked to the abuse.6

While childhood sexual abuse can happen in any community, factors like poverty, homelessness, loss and racism can increase the risk. In BC, youth who are homeless are much more likely to have experienced sexual abuse.7,8

Recognizing men

It’s thought that about one in six boys or young men are survivors* of sexual abuse. But men are much less likely than women to be recognized as victims of sexual abuse, much less likely to be taken seriously and much less likely to receive treatment. Male survivors of childhood sexual abuse are also often viewed as less vulnerable than women, and mental health professionals may be less likely to ask men or recognize sexual abuse.9


How does childhood sexual abuse affect adult well-being?

Childhood sexual abuse can have a wide range of effects in adulthood. Some adult survivors experience few mental health problems, while others experience many mental health problems. Abuse is a kind of trauma. Trauma is a situation that’s shocking, intense and distressing. The effects of trauma include a complicated mix of factors, such as:

  • The amount of any kind of trauma you previously experienced

  • The severity of the trauma

  • How close you were to the person who abused you

  • How long the abuse lasted

  • How people you trusted reacted to the abuse, if you told them—did they believe you and support you or dismiss you?10

Here are some of the ways that experiences of childhood sexual abuse can affect well-being:

  • Trust—Abuse may impair your sense that the world is a safe place and impair your ability to trust others. This may be particularly difficult if you had a close relationship with the abuser.11

  • Self-esteem—You may blame yourself for the abuse, even though it isn’t your fault. You may have a hard time feeling good about yourself or hopeful about your future.12

  • Coping with stress—You may have a lot of negative feelings, which may make it hard to cope with everyday stress.12

  • Impulsivity—Impulsivity means acting on urges before thinking through the consequences, which can lead to risky activities.12

  • Anger—You may have a hard time controlling your anger.12

  • Dissociation—With dissociation, your mind “separates” itself from painful events to protect itself. You may have a hard time remembering what happened, feel like the world around you isn’t real or feel like you aren’t connected to your body. It’s a common reaction to pain and fear.13

  • Self-harm—You may harm yourself, but not intend to end your life. It may be a way to cope with difficult thoughts or feelings.14

These are common reactions to trauma. But they can lead to problems when they affect the way you live your life. It’s important to get help if you are having a hard time coping with past trauma.

Other problems linked to childhood sexual abuse include:

  • Mental illness—Experiencing childhood sexual abuse does not mean that you will develop a mental illness, but it is one of many risk factors. People who experience childhood sexual abuse may have a higher risk of experiencing anxiety disorders (such as post-traumatic stress disorder),15 depression,16 eating disorders,16 dissociative disorders17 and personality disorders.18

  • Substance use problems—Survivors of childhood sexual abuse are at greater risk of developing problems with alcohol and other drugs19,20,21 and may be more likely to start using substances at a younger age.22,23,24,25 There may also be a link between your response to childhood sexual abuse (such as depression, low self-esteem or post-traumatic stress disorder) and the risk of experiencing problems with substances.19,21,26 Substances may be a way to cope with difficult experiences.19,21


Revictimization means that you experience abuse again at another time in your life. People who experience childhood sexual abuse are two to three times more likely to experience abuse as adults. Childhood abuse may affect the way adults interprets warning signs, understand trust and control in relationships, and expect others to act in relationships.27


What can I do about it?

It's important to find help as soon as you can. Connecting with others who care about and support you as early as possible can help protect you from the negative impact of childhood sexual abuse and help you heal. Unfortunately, many people feel that talking about childhood sexual abuse is taboo, even though we know it happens and know that it's a crime. Some survivors are cut off from supports like family, friends and community members when they talk about their experiences. This isolation can make it harder to heal and feel well again. If you aren't sure who you can talk to, check out the resources in the next section of this

You can also find help for problems associated with childhood sexual abuse. Treatment for adult survivors may help you:

  • Overcome troubling thoughts and feelings, like self-blame, guilt or low self-esteem

  • Overcome unhelpful coping strategies, like self-harm or eating problems

  • Build healthy skills, like building trust and setting healthy boundaries in relationships

Treatment should also address any other mental health or substance use problems, so it will look different for everyone.

Remember, you may have experienced traumatic events in the past, but people can help now. It is never too late to find help.28

In this fact sheet, we use the term "survivor" to describe anyone who has experienced abuse because it's the term used most often in research. People who experience sexual abuse can and do survive and thrive.28
