Biological effects of parenting
• Sixfold rise in cortisol in adolescent rats stressed by eye puff who were separated from mother 3hrs a day for a week as infants (Meaney)
• Elevated CRP in adult humans exposed to harsher parenting as children (Danesi, 2009 Archives Gen Psychiatry)
• Emerging evidence of specific genes conferring sensitivity to parenting (not just vulnerability a la Caspi 2003 for MAOA)
• But will treatment reverse this? Fisher 2007

Brain in conduct disorderRubia, Scott, Taylor et al (2008). Am J Psychiatry
Sustained Attention
RewardCD < C, ADHD
Child characteristics affect parenting, and may be genetically
determined Abuse commoner in irritable, premature babies Some child characteristics strongly genetically
determined Callous –unemotional traits within antisocial behaviour
(80% heritability vs 30% without; Viding et al 2009) ADHD Intellectual disability
“Cold CD” - CU traits
Callous – unemotional style Lacking empathy Lacking guilt Unkind Predatory aggression
Still from LeRoy’s “The Bad Seed” (1956)
Callous Unemotional Traits
At the core of psychopathy (Cleckley 1941; Hare) In psychopathy, also impulsiveness, narcissism
Distinguishable from autistic traits CU can understand emotions, but don’t react ASD can’t understand others’ feelings/views
Distinguishable from ADHD In psychopathy not restless, can concentrate

Individual intervention for conduct problems
Clinical trial (Scott, Spender et al 2001, BMJ)
• 141 children age 3-7 referred to CAMHS
• severe, persistent antisocial behaviour (worst 1%)
• ‘Incredible Years’ parenting programme:
– videotapes shown in group, 3 wks each of • Play
• praise & rewards
• setting limits
• handling misbehaviour
Antisocial Behaviour Before and after intervention
(percentile level; p<0.0001; Scott et al., 2001)
Do good parenting programmes in childhood having enduring effects and prevent the emergence of antisocial personality traits?
Long-term follow-up of two controlled trials: The SPACE study
Antisocial Personality
• APD (Antisocial Personality Disorder) affects 1% of females and 3% of males
• No successful treatment in adulthood• Origins in childhood• Two main components – persistent antisocial
behaviour and callous-unemotional traits – CU traits can be reliably detected by age 7
Antisocial Personality: Prevention
Evidence from two controlled trials:
a) clinical trial (BMJ) b) community sample (‘SPOKES’)
Long-term follow up
• Follow up 2005-07 7-10 years later of 94
children now aged 10-17 (mean 13)
• Intention to treat, 74 allocated to IY, 20
controls received treatment as usual
Parenting effects
• No effect on Alabama qu’re, Parent or Child
• No effect on directly observed parent-youth
interaction (Oregon “hot topics”)

Comment• Gratifying to have enduring effects on antisocial
behaviour and antisocial personality traits 7-10 years later
• Surprising to have reading effects – objectively tested
• The lack of effects at school (though a weak measure) and in the community argue for a teacher programme
• Our trial of universal IY in 24 schools, measuring worst 3 kids in class aged 3-6 in Jamaica found effect size of .42 on ODD, .74 on friendship skills (Baker-Henningham, Taylor, Scott & Walker, 2012)

Therefore, logical intervention should target more than one risk
factor:
•Improve parenting•Reduce antisocial behaviour•Improve focus and attention•Improve reading attainment•(address delinquent peer group in adolescence)
the SPOKES Programme in schools
(Scott, Sylva et al 2010, JCPP)
Address a whole population Get them young Engage the most deprived Address child behaviour AND learning Use the most effective interventions Make it normal and fun

HCA Study Questions
Which intervention changes which outcome?
1. Does the IY intervention improve relationships & antisocial behaviour, but not reading?
2. Does the literacy intervention improve child reading but not antisocial behaviour?
3. Does giving both programmes enhance both outcomes?

Commissioning Toolkitwww.education.gov.uk/commissioning-toolkit
Over 160 programmes submitted themselves136 met criteria of a parenting programme18 had RCT evidenceWe also evaluated
1 theory & quality of content, 2 Appropriateness for target population 3 quality of training materials & procedures
Correlation between 4 elements 0.7- the notion that there are many excellent unevaluated programmes out there not true
‘… the habit of self-abuse notably gives rise to a particular and disagreeable form of insanity, characterized by intense self-feeling and conceit, loss of mental energy, hypochondriacal brooding, pitiful vacillation, extreme perversion of feeling, and corresponding derangement of thought, in the earlier stages; and later, by failure of intelligence, nocturnal hallucinations of a painful character, and suicidal or homicidal propensities.’
