Adverse Childhood Experiences too High? Educating Yorkshire in ACEs awareness

The concept of Adverse Childhood Experiences (ACEs) and their effects upon later adult life is becoming a much discussed meme across the western world. It is time to look a little more closely at such ideas and consider their validity. In this blog, Dr Pam Jarvis, Reader in Childhood, Youth and Education at Leeds Trinity University, considers ACEs in this spotlight, and argues that the concept has a clear relevance and application for practice with children and families going forward into the twenty first century.

The basic ACEs theory is demonstrated in the following diagram:

The original study to explore the concept of ACEs was that of Felitti et al in 1998. The researchers carried out a large-scale analysis of the effects of a range of childhood stressors upon both mental and physical health in later life and found a number of statistically significant effects. Film maker James Redford, son of actor Robert Redford, came across an article disseminating the research findings and thought the ideas within it should be raised more prominently within the public eye (Cocozza 2017). In order to achieve this he made a film entitled Resilience: the biology of stress and the science of hope which has now been widely distributed across the western world.

Redford compares the constant stress that some children live under as comparable to arriving home every night to find a bear in the living room; that the mentally ill or abusive parent, or the effects of ongoing poverty upon the family is likely to have long term adverse effects: 'day after day, those chemicals – the adrenaline, cortisol, the process of high sugar, that whole response, changes the way your brain processes information. It affects the development of the organs on a cellular level. This continual exposure to stress wears the body down' (Cocozza 2017, online).

ACEs research has continued across the world, making very similar findings to Felliti et al (1998). Recent large-scale studies in Wales (Bellis et al 2015) and Scotland (Couper and Mackie 2016) have linked poor mental and physical health in adulthood to childhood ACEs, while clear links have been drawn between ACEs, poverty and parenting stress (Steele et al 2016). Of course, human beings are the sum of all their experiences, which makes isolating cause and effect extremely difficult.

This issue has been raised by those criticising the ACEs concept, who propose that it may create a deficiency model through the construction of a self-fulfilling prophecy, depicting individuals simplistically as victims of circumstance, with little ability to control their own destinies, leading to stereotyping and stigma (Edwards et al 2017). These researchers also express concerns about the problem of simplistic tick box screening being developed by amateurs, which may subsequently be used to promote shallow concepts of building resilience through counselling, rather than exploring solutions to the root causes.

These are of course highly valid concerns, but at the level of how we as a society respond to the concept of ACEs, rather than whether the effects actually exist or not. It is, however, useful to note that the practice of simplistic screening leading to self fulfilling prophecies must certainly be stringently avoided as a more ACEs aware society develops.

Edwards et al's more far reaching criticism – that ACEs is a retrospective model based on adults' recall of childhood events, and may therefore lack reliability and validity (2017) is partially countered by the findings of Barboza Solis et al (2015) who found evidence of ACEs effects in the 1958 British birth cohort study, and by Horowitz et al (2001) who created a sample of participants from records of those who had experienced childhood adversity, and then exploring whether ACEs were a factor in their adult lives.

Both studies found evidence of ACEs effects, and additionally that later life events and gender were also significant influencing factors. Dube et al (2003) found evidence of ACEs effects in a US study dating back to participants born in the early 1900s. They concluded that although 'ACEs rarely occur in has been shown that the limbic system, which is responsible for emotional response, is adversely affected' (p.274).

People with significant ACE loads, having experienced toxic stress in childhood, enter adulthood with a stress 'thermostat' that is chronically set at too high a level, in the same manner as a central heating system that has been set at maximum heat, which puts constant pressure on the boiler, so that when the thermostat is advanced even further by stressors in the day-to-day environment, the system becomes increasingly likely to 'blow', see diagram.

The effect of the stress in early childhood through disruption of the human attachment process has also been extensively studied. Neurobiologists have investigated potential dysfunctions in the limbic system created by the modern practice of placing young infants in mass day care settings for very long hours. In 2014, I carried out a review of this research and proposed on the basis of my findings that as a society we should urgently explore more creative care initiatives for children under three; options that are better 'designed to support families and neighbourhoods to become more secure, less alienated environments, thereby nurturing the social and emotional resilience of our rising generations' (Jarvis 2014, online). I also later explored some of the more practical implications (Jarvis 2016).

Besides the more obvious socio-emotional and behaviour problems created by cortisol disturbance, it has also been linked with memory and learning problems (Steele et al 2016), which I considered in my blog Banish Baseline, Beat Poverty Instead (Jarvis 2017).  Links have additionally been drawn between adult attachment anxiety and cortisol dysfunction (Quirin et al 2008) and between 'toxic stress' and cortisol dysfunction (Oral et al 2015). Burke Harris (2018 p.187) reflects that it is a far more challenging prospect to build healthy attachment relationships and carry out calm, focused nurturing in families who are coping with poverty. It is becoming increasingly clear that categories of ACEs will continue to be refined as the effects are more widely studied, and that we will become more intricately aware of some of the more insidious effects of everyday stressors such as poverty and infant attachment disturbances.

Some of these more subtle and transactional effects are already emerging from ACEs research, particularly with respect to attachment. Tharner (2011, p.162) found that 'parenting stress explained the most variance in child emotional and behaviour problems' but that 'in families with high parenting stress securely attached children had fewer socio-emotional problems than insecurely attached children'. Shonkoff et al (2015) found that even just one supportive adult-child relationship in early childhood could blunt the impact of ACEs. These researchers propose that 'resilience requires relationships' (p.7) and that it can be strengthened by relationships at any point in childhood. Their checklist of important protective factors is illustrated in the following diagram.

Finally, it is important to remember that ACEs tend to be passed from generation to generation if parents do not receive support to reflect upon childhood stressors, and to explore how these may feed into current problematic behaviours and ongoing health issues. The aim of working with adults with high ACE scores should therefore be to help them to understand how their body and brain have been primed by their childhood environment. Just as we must guard against shallow screening exercises that label and 'victimise' children, so we must guard against doing the same thing to their parents. Sandra Bloom (1995, p.413) comments in her pre-ACEs article Sanctuary in the Classroom that instead of taking the approach 'what's wrong with you?' we need to ask 'what happened to you?' and 'how can we help?' This is important for both children and adults. As Burke Harris (2018, p.219) points out, 'how adversity affects you is not a referendum on your character. We don't need to play the shame game'.

Of course, the ultimate aim for ACEs informed practice is to create a society in which ACEs occur far less frequently, and where they do, the child and the family are offered support at the earliest opportunity. Will this be very expensive for the nation? Most certainly. But in the end in such a society, taxpayers will not be required to contribute so much to adult health, social care and criminal justice systems, spending less on average on each individual over a 'whole life' basis. And of course, far more of the population will have an experience of life that is far more pleasant than they do at the moment. The answer to those who propose that we cannot afford to address ACEs on a national scale is that what we actually cannot afford is to continue to sleepwalk into a society that is incrementally losing connection to human emotional needs.
