What Are Adverse Childhood Experiences?
The term Adverse Childhood Experiences was developed in a pivotal study conducted at Kaiser Permanente between 1995 and 1997. More than 17,000 people answered questions about their childhood experiences. Collected data was then analyzed in consideration with their current health and life situation. The study found a tight association between Adverse Childhood Experiences (ACEs) and the presence of a host of negative outcomes in adulthood.
The Adverse Childhood Experiences Study
The original Adverse Childhood Experiences study used a questionnaire that asked about ten kinds of adverse experiences. There werethree categories of adverse experiences: abuse, household challenges, and neglect. The Adverse Childhood Experiences scale used to measure an individual experience of:
- Emotional abuse: being regularly belittled, humiliated, insulted, or demeaned, all of which may lead one to fear for their physical safety.
- Physical abuse: being struck, pushed, grabbed, etc. with enough force to injure or leave marks.
- Sexual abuse: beingforced to engage in a sexual interaction.
- Mother treated violently:mother or stepmother subjected to violence by a male partner.
- Household substance abuse: alcoholism or illicit drug use by a household member.
- Mental illness in the household: depression or other mental illness experienced by another household member. This category may also include suicide or suicide attempts.
- Parental separation or divorce
- Criminal household member: being in a household where one or more members are imprisoned or engaged in criminal activities.
- Emotional neglect: lack of love and support.
- Physical neglect: lack of physical necessities and basic needs like food, shelter, or clothing; parental incompetence.
How Many People Are Affected By ACEs?
The original study found that around two-thirds of the people who took the questionnaire had experienced one or more ACE. About one-fifth of the respondents had experienced three or more ACEs.
The results of the Adverse Childhood Experiences study were clear and sobering.
- Adults With high ACE Scores Are Less Physically Healthy
Heart disease, liver disease, diabetes, cancer, and strokes are all more common in adults with high ACE scores. Also, high scores often predict autoimmune diseases in women. This correlation may be partly due to the effect of chronic stress on developing brains.
Childhood is a time of incredible physical growth and cognitive development. Leaving behind the old nature versus nurture debate, we now know that the genes that we are born with respond to the environment in which we develop. That environment, in turn, responds to us. And when our environment is chronically stressful, it inhibits the development of genes that manage stress. Chronic stress can change a child's development at the genetic level, setting their stress response in permanent overdrive.
Life is full of regular stressors; long lines, frustrating coworkers, new jobs, and bad traffic, to name a few. These are generally dealt with easily by healthy adults. But adults with a high ACE score, who may have their stress responses stuck in overdrive, are unable to regulate their stress response in the same way, for which their response to stress may seem rather disproportionate.
Being in a constant high stress response mode, can promote chronic inflammation, dampen a person's immune system, and impair their bodies' regular maintenance and rebuilding. Stress hormones themselves can be disruptive to physical function in the long term. In addition, high-stress responses exhaust a great deal of energy, which, in turn, compromise other physiological functioning and routine processes.
The physical health consequences of ACEs are not all caused by unmanaged adult stress, however. There is some evidence that constant, unregulated childhood stresses trigger changes within the genes that are directly related to the development of many of the adult diseases to which this population is prone. Hence, a high ACE score doesn't just set the bomb of chronic adult stress, but it sneaks into the very genes responsible for physical health, and alters them.
- Adults With High ACE Scores Are Less Mentally Healthy
The effects of Adverse Childhood Experiences (ACEs) on adult mental health is perhaps less surprising than their effects on physical health. Many of us are familiar with the idea that our early experiences play a part in our adult mental health. What may be surprising, however, is that ACEs affect mental health in much of the same way they affect physical health -that is, by triggering actual physiological changes in our bodies.
When a child experiences chronic, unsupported stress, it affects their genes, as we previously discussed. It also changes the shape of their brain. Excessive and ongoing exposure to stress hormones can trigger several changes at the cognitive level, including shrinkage of the parts of the brain that are responsible for learning and memory, under-development of the part of thebrain that processes fear, and deficits in decision making and impulse control centers.
The biggest mental health risk for adults with high ACE scores is depression. People with high ACE scores suffer more depressive episodes, and it takes them longer to recover from these episodes. They are also more likely to commit suicide than the general population. The physical challenges of chronic stress in childhood and adulthood that we looked at earlier help to explain some of the prevalence of depression.
In addition to depression, people with high ACE scores are also more likely to suffer from generalized mental distress than the general population. ACEs can contribute to the development of Post-Traumatic Stress Disorder.
- Adults With High ACE Scores Are Less Socially Stable
Partly due to disrupted brain development, people with high ACE scores are more likely to engage in personally and socially risky behaviors. High ACE scores are associated with earlier and riskier sexual activities and higher rates of unintended pregnancies, as well as, smoking, alcoholism, and use of illegal drugs.
As we discussed in the physical and mental health sections, the chronic, unsupported stress of ACEs can cause physical changes to our brains. The chronic stress of ACEs can inhibit the development of decision-making and impulse control centers. This leaves adults with high ACE scores more susceptible to potentiallyunsafe activities, as excessive use of drug and/or alcohol.
In addition to these risky behaviors, adults with high ACE scores are more likely to report poor work performance or unemployment. They are more likely to have multiple sexual partners and are at higher risk of sexual violence and intimate partner violence.
It's not always clear how ACEs are related to these results. Some of the social issues may stem from the impacts of stress on decision making and impulse control. Also, research on childhood trauma shows that early relationships and attachment style carry over into adulthood. If the ACEs indicate unhealthy patterns in relating to authority figures or family members, these are often very difficult to break later on.
Brain development and learned behavioral patterns seem to play a part in the social instability of adults with high ACE scores. In addition to these, high sensitivity to stress can make challenges in the workplace or in intimate relationships difficult to deal with. As we saw earlier, chronic, unsupported childhood stress can cause excessive stress reaction to triggers, later on as adults.
- Adults With High ACE Scores Die Earlier
All of the challenges detailed above add up to one bald fact: adults with high ACE scores have a life expectancy that is 20 years shorterthan that of the average adult, when compared to the general population.
Adults with high ACE scores often die of the diseases to which they are prone; suicide, alcoholism, and drug use, to name a few.ACEs lay the foundation for impaired brain development, which essentially contributes to certain mental health disorders, risky behaviors, and social instability. Often, this unfortunatetriad ultimately results in increased risk of early death.
What if you took the test and scored above a three, four, six, or eight? Does that mean that you aredoomed to a lifetime of low-achievement, sickness, and instability followed by an early death? The short answer, is - no.
While the Adverse Childhood Experiences scale measures particularly difficult childhood circumstances that can stack the deck against us in adulthood, it doesn't measure everything. There are positive childhood circumstances that can mitigate a lot of the damage of a high ACE score. Loving, supportive relationships with adults like teacher, grandparents, or friends can go a long way towards helping children cope with even severe trauma. And as an adult, self-knowledge, like your ACE score, is only a tool. It can help you to identify and name detrimental actions. It can help you get help.
Many people with high ACE scores live long and productive lives. But if you are concerned that your ACEs may be interfering with the life that you want to live, consider consulting a caring, trained professional. Therapists and counselors like those at BetterHelpcan help you identify and overcome problematic behaviors. They may be able to help you heal the wounds of your childhood experiences, or identify ways that patterns built in childhood, are inhibiting your ability to function as an adult.
