What is Psychopathy
A personality disorder...
“…an enduring pattern of inner experience
and behaviour that deviates markedly from
the expectations of the individuals culture, is
pervasive and inflexible, has an onset in
adolescence or early adulthood, is stable over
time, and leads to distress or impairment”
(DSM-IV, APA, 1994, p. 629)
Manie sans delire (Pinel, 1800s)
…individuals engaging in deviant behavior
but exhibiting no signs of a mental illness or
disorder…
The Mask of Sanity (Clecley 1971)

Risk Assessment
“...psychopathy is such a robust and important risk
factor for violence [in adults] that failure to consider it
may constitute professional negligence...”
Hart, 1998, p.133
“However, it would also be negligent to base a risk
assessment on a single risk factor such as psychopathy”.
Hart, 1998, p.133
Psychopathy might be causal...
•Sensitive to slights
•Narcissistic Injury
•Dominance
Impulsive and
Irresponsible
Behavioural
Style
Arrogant &
Deceitful
Interpersonal
Style
•Lacks emotional inhibitors to violence
•No anticipatory guilt or empathy
Deficient
Affective
Experience
•Opportunistic crimes
•Poor temper control
“...it is a reasonable assumption that
the socially deviant behaviour of
many offenders is a function of
personality disorder...”
Blackburn, 1992, p.70

Utility of PCL:YV
Reliability: “good” (Forth et al., 2003)
Prevalence: 20-30% of institutionalized
adolescent males and 10% of those on
probation show significant traits (Forth et
al., 2003; Salekin et al, 2004

Construct Validity
Meta-analysis of recidivism data across 21
samples of juvenile offenders
P significantly associated with general and
violent recidivism (r=.24 and r = .25) but
negligibly with sexual recidivism
Considerable heterogeneity with some
variance explained by gender and ethnicity of
samples
‘Associated but ES’s low’
10 year follow-up of 75 male offenders
Neither total nor factor scores predicted
general or violent reconvictions
“These results raise the prospect that
141 juveniles with high PLC:YV scores followed-up over 2

Mental Disorders
• substance misuse
problems (Murrie et al.,
2004; Corrado et al.,
2004)
• Personality disorders
(Myers et al., 1995)
• Axis 1 disorders*
(Schmidt et al., 2006)
Antisocial Process
Screening Device
(ASPD; Frick & Hare,
2001)
“the APSD screens for
Antisocial Personality
Disorder or psychopathy.
The child is rated on a
dimensional scale that
probes the characteristic
psychopathic pattern”
APSD
• 20 Items
• Parent rating scale
• Teacher rating scale (must
have known the child for 2
months)
• Both completed in under
10 minutes
• Clinician time required
approx. 10 minutes
Interpretation T scores
Above 70 – Markedly Atypical – Highly Antisocial
66 to 70 – Moderately Atypical
61 to 65 – Mildly Atypical
56 to 60 – Slightly Atypical
45 to 55 – Average
Below 45 – Below Average – Good/low antisocial

Traits
CU was associated with more
severe conduct problems in
community and clinic referred
children
• Thrill and Adventure Seeking (Frick et al., 2003; Frick et al.
1999)
• Lower sensitivity to cues to punishment when a rewardoriented response set is primed (O’Brien & Frick, 1996; Frick
et al., 2003)
• Lower levels of reactivity to threatening and emotionally
distressing stimuli (Blair, 1999)
• Less distressed by the negative effects of their behaviour on
others (Blair, 1997)
• Impaired ability to recognize fearful and sad facial expressions
and sad vocal tones (Blair et al., 2001; Stevens et al., 2001)
• Impairments in moral reasoning and empathic concern (Blair,
1999)
Stability
• ASPD showing reasonable stability over 4
years (Frick et al. 2003)
APSD is highly correlated with
other measures of Disruptive
Behaviour Disorders of
Childhood
Non-laboratory measures of emotion
Developmental indices of emotion
Socialisation of moral affect and
inductive parenting
Reliability has been poor
Developmental Challenges
Homotypic and Heterotypic Continuity
Homotypic Continuity: Identical behavioural
expression of an underlying process across
different developmental stages - this is rare
(Kagan, 1971)
Heterotypic Continuity: Changing
behavioural manifestation of the same
developmental process – more likely
Caspi (2000) illustrated this concept:
The undercontrolled child who has daily temper tantrums in
early childhood may refrain from this behaviour as an adult. But
if he emerged into adulthood as a man who is irritable and
moody, we may grant that the surface behaviour has changed
but claim that the underlying personality type has not. Although
the form of behaviour changes over time, the course of
personality is said to evidence coherence if the qualities of
behaviour are preserved over time (p. 168)
Transient Developmental Phenomena
(Seagrave and Grisso, 2002)
Arrogant and Deceitful.......or..... Immature theory of mind,
egocentricism common
to youth (Piaget, 1972,
1973)
Irresponsible/Impulsive......or.......”normal “ sensation seeking
and lack of
consequential thinking
Deficient Affective Experience...or.....Egocentricism
Aetiology
• Assumed biological primacy
• What about Inductive parenting??
• Direction of effects
– Transactional
– Interactional
– Unidirectional
– Bi-directional
• Absence of empirical data providing
conclusive evidence
Equifinality and Multifinality
Attachment
Trauma
Parenting
Genetic
Differential Diagnoses
1) ADHD + Attachment Disorder + Conduct
Disorder
2) Prodromal phase of psychosis
3) Developmental disorders (Autism, Asperger)
Potentially Useful
Construct
Key differences with the
adult literature and
developmental concerns
Priority for Research
Implications for the practitioner
• How can the construct be meaningfully
applied in forensic child and adolescent
settings?
Clinical use should be for speculation, not
diagnosis or decision making
