prior to 2002 - dichotomy = either dangerous or not

now - range/degree - prediction (probability and risk factors) and management (treatments etc.)

Q

Monahan and Steadman

A

3 weaknesses in violence prediciton

  1. limited number of risk factors studied
  2. how criterion variable is measured - official records underestimates violenmce - not reported/ found
    - when records combined with interviews, rates increase
    - base rate increases from 4.5 - 27.5% (6 times higher)
  3. how criterion variable defined - violent or not
    - change to severity, type, target, location, and motivation

Q

Unstructured clinical judgement

A

professional discretion and lack of guidelines
- Grove and Meehl - “ informal in the head subjective…”
Pros: flexible, widely applicable, inform treatment and prevention
Cons: highly subjective and inconsistent, questionably relevant outcome, elude scrutiny

Q

Actuarial Approach

A

Decisions are based on risk factors that are selected and combined based on their empirical or statistical association with a specific outcome. No clinical judgement
pros: demonstrated link btw risk factors and outcomes, reliability btw raters, consistency across time, transparency
limits:
estimates may not generalize to new samples, predictive properties may change in different contexts, constrained use, under samples risk
ex. Violence risk appraisal guide

Q

Dr. James Grigson

Study These Flashcards
A

Dr. death - testified in death penalty cases
- 100% certainty would kill again etc.
estelle v. smith - smith “ severe sociopath” bc lacked remorse
- Randall Adams - declared sociopath based off 15 min interview - sentenced to death - released after another inmate confessed
- 1995 expelled from APA for ethical violations

24
Q

Structured Professional Judgement

Study These Flashcards
A

Decisions are guided by a predetermined list of risk
factors that have been selected from the research and professional literature. Judgment of risk level is based on the evaluator’s professional judgment
- final decision uses discretion
- allows idiographic risk factors - flexibility and case specific
- relevance to management and prevention
- reflects current themes in field - risk is ongoing, dynamic, and requires re-assessment
- Limitations : expertise (training), and time (comprehensive assessment not just screening)

25
static risk factors
Risk factors that do not fluctuate over time and are not amenable to change (e.g., criminal history) also historical risk factors
26
Dynamic risk factors
Risk factors that fluctuate over time and are amenable to change (e.g., antisocial attitude, mental state, substance use etc.) also criminogenic needs
27
Dispositional risk factors
Risk factors that reflect the individual’s | traits, tendencies, or styles (e.g., negative attitudes
28
clinical risk factors
Types and symptoms of mental disorders (e.g., substance abuse)
29
contextual risk factors
Risk factors that refer to aspects of the current environment (e.g., access to victims or weapons). Sometimes called situational risk factors
30
Demographic risk factors
age- younger 1st offense, greater chance engage in criminal behaviour sex - males higher risk for general offending and more serious violent acts, females less serious violence
31
personality risk factors
- impulsiveness - increases likelihood of engaging in crime and violence - lifestyle impulsivity distinguishes recidivistic rapists - psychopathy - moderatly related to recidivism and violence in prison - predicts reoffending across different countries in both males and females, mental disorders, male adolescents, sexual offenders - weakly related to violent reoffending in adolescent females - psychopathy and deviant sexual arousal predicts sexual recidivism
32
deviant sexual arousal
sexual offender shows relative preference for inappropriate stimuli such as children and violent nonconsensual sex
33
terrorism risk factors
Monahan 2012 : age - 20-29 gender- most males, depends on group, female able to get closer to targets marital status - single social class - representative of local population, suicide terr = more highly educated prior crime - usually no record - 6% committed again (bergman) suicidality - differ greatly from general suicidal public mental illness - low rates substance use - very rare psychopathy - low rates Malik et al. : 1. social wellbeing 2. economic indicators 3. governance 4. law enforcement 5. armed conflict
34
past behaviour as risk factor
past violent and non violent behaviour predict future risk for violence
35
age of onset
earlier start = more chronic and serious offenders farrington - 50% of boys who committed prior to 16 committed again Elliott - 50% boys before 11, 30% btw 11-13, 10% adolescent females not predictor
36
childhood history
maltreatment - physical abuse/ neglect - increased risk for violence - sexual abuse - no more likely - childhood abuse predicts initiated delinquency - prolonged abuse predicts chronic offending - physical abuse in adolescents directly related to adolescent offending
37
chaiken and chaicken
severe drug users commit 15 - 20 x more robberies and burglaries
38
types of drugs and crimes
heroin associated most with crimes heroin and crack greatest risk for property crimes some cases depends on amount of drug used drug use moderately related to recidivism
39
substance use
swanson survey - men/women less than 3% with no disorder committed violence vs substance use men 22%, women 17% violence morley et al. - violent behaviour associated with all drugs - high risk associated with more serious polysubstance abuse
40
mental disorder risk factor
- affective disorder and schiz. higher rates - suicide attempts/ self harm history - more likely verbal/ physical aggression to others douglas, guy, hart - psychosis 49-68% increase in violence odds - link depends on study design, measurement, timing of symptoms/violence
41
social support
instrumental emotional appraisal information
42
access to weapons/ victims
released to environment with access/ around other antisocial ppl, potential for violence increases
43
Static -99
10 item acturial scale to predict sexual recidivism (0-12) - age at time of release - lived with previous intimate partner - prior nonsexual violence - index nonsexual violence - # of prior sex offenses - # prior offenses - male victims - unrelated victims - stranger victims - noncontact sex offenses
44
Violence risk appraisal Guide (VRAG)
``` acturial predict violence from prior violent episodes - made by quincey et al. from 685 violent offenders - need to be charged to be counted ( needs record) risk factors: psychopathy checklist (PCL-R) - positive relationship, 70% of decisions elementary maladjustment DSM-III personality disorder age at index offense separated from parents before 16 failure on prior conditional release property offense marital status schizophrenia victim injury alcohol abuse female victim ```
45
Douglas, Hart, Dempster, Lyon
VRAG replication from quincey data - results were not the same - depends on subset of individuals used for coding the VRAG also needs to be same n to be more accurate - estimates may not generalize to new samples, predictive properties may change in different contexts, constrained use, under samples risk
46
Paul bernardo
scarborough rapist | actuarial VRAG example - only 17-31% chance of violence
47
administering SPJ
1. relevant information from multiple sources 2. presence of risk factors 3. relevance of risk factors 4. formulation of violence risk / case formulation 5. primary scenarios of violence 6. case management plans 7. final opinions - low moderate or high
48
HCR-20
SPJ approach to predict future violence in correctional and forensic samples - Historical (static) documented - 10 ex violence, antisocial, relationship, employment etc. - clinical (dynamic) present/observed - 5 ex. insight, violent intent, mental disorder, instability, treatment response - Future (speculative) projected - 5 = RISK MANAGEMENT ex. professional services, living situation, support, treatment response, stress
49
Guy (2008)
compared SPJ and actuarial | both good at predicting future violence
50
Recidivism process
Precipitating situation (stressor) - cognitive and emotional appraisal - a. individual influences ( psychopathy, emotional reactivity) - criminal bevaviour - b. available response mechanism (social support, coping) - criminal behaviour
51
female offenders
- less criminal behaviour - more prostitution charges - more likely to target family - reoffend at lower rate - childhood victimization is higher than men - more serious mental illnesses - about same risk factors + history of self-injury or attempted suicide, and self-esteem problems - being married is a risk factor for women! - LSI-R - substance use more associated with recidivism than males
52
aboriginal offenders
culturally relevant risk factors | risk assessment tools not as accurate
53
Ashley Smith
suicide in prison while on suicide watch death ruled homicide last year transferred 17 times - no treatment plan
54
Ewert v. Canada
risk assessments not valid for aboriginal offenders | overturned in 2016
55
protective factors | and how to measure
factors that mitigate or reduce the likelihood of negative outcome - more research in youth - prosocial involvement, social support, social orientation, attachments, intelligence - high risk offenders - employment stability - low risk males - family connections - male sex offenders - professional and social support, structured group activities, goal directed living START - assesses weaknesses and strengths
56
Desistance
process of ceasing to engage in criminal behaviour
57
Haggard et al.
why high risk offenders stop offending - insight triggered by negative events connected to criminal lifestyle - social avoidance - orientation to the family
