The Promise of Prevention for Conduct Problems in At-risk Youth: Findings from the Fast Track Project Bob McMahon Department of Psychology University of Washington April 19, 2010
2
FAST TRACK Developmental Model Research Design Intervention Model Findings
3
“EARLY STARTER” DEVELOPMENTAL PATHWAY Preschool/Early School-Age Onset Overt and Covert Behaviors High Degree of Continuity Poor Prognosis Enormous Societal Cost “ Career Criminal” = $1.3 million (Cohen, 1998)
4
“EARLY STARTER” PATHWAY TO ANTISOCIAL BEHAVIOR Preschool Years Early Education Years Early Education Years Early Adolescence Early child, family, and community risk factors Poor school readiness in cognitive, social, and emotional domains Academic failure Peer rejection Social coping deficits Adult support/ supervision Academic failure Peer rejection Social coping deficits Adult support/ supervision Deviant peers Poor adult monitoring Alienation/ depression Deviant peers Poor adult monitoring Alienation/ depression Increased and Diversified Antisocial Behavior School Entry
5
Preschool Years Elementary and Middle School Years Adulthood Adolescence Serious antisocial activity School drop-out and failure Substance use Early/risky sexual activity Comorbid psychiatric disorders DEVELOPMENTAL MODEL
6
Preschool Years Elementary and Middle School Years Adolescence Adulthood Psychological problems Criminal behavior Poor educ/occup adjustment Marital disruption Increased mortality DEVELOPMENTAL MODEL
7
IMPLICATIONS OF THE DEVELOPMENTAL MODEL FOR INTERVENTION DESIGN Multiple Skill Domains Multiple Socialization Support Systems Sustained, Well-Integrated Developmentally and Culturally Informed

RESEARCH PARTICIPATION - SAMPLE x SITE (% IN YEAR 11)
31
DID STRATEGIES WORK? PARTICIPATION IN PARENT AND CHILD GROUP
33
INTERVENTION EFFECTS Data Analytic Strategy “Intent To Intervene” Model “Once Randomized, Always Analyzed” Regardless of Extent to Which Families Participated in Intervention, Considered Part of Intervention Sample for Analyses
34
KEY QUESTIONS Does Fast Track Work? How Does It Work? Does It Work Equally Well for Everyone? How Much Does It Cost?
35
Modest Intervention Effects in Multiple Domains Through Elementary School Both high-risk (and universal) samples Effect sizes strongest following initial intensive prevention efforts Small to moderate effect sizes maintained with sustained prevention support DOES FAST TRACK WORK? Elementary School (Grades 1-5)
36
Classroom-level Analyses Peer Sociometrics Aggression, activity-disruption Classroom Atmosphere Prediction of Outcome Quality of teacher implementation Dosage (# of lessons) not strong predictor DOES FAST TRACK WORK? PATHS Universal Intervention End of Grade 1 CPPRG (1999b)
37
Youth present throughout Grades 1,2, and 3 (n=2,937) Aggression (T,P), Academic Engagement (T), Social Competence (T), Hyperactive/ disruptive (P) Teacher Ratings Moderated by School Environment Stronger in less disadvantaged schools ↑ baseline aggression – ↑ effects on aggression Peer Ratings Moderated by Gender Effects limited to boys DOES FAST TRACK WORK? PATHS Universal Intervention End of Grade 3 CPPRG (2010)
38
DOES FAST TRACK WORK? Middle School Do Not Find the Broad Effects on Aggressive and Externalizing Behavior Seen in Elementary School Lower Levels of Hyperactive Behaviors (Behavioral Inhibition) at Grade 7 More Deviant Peer Involvement in Grades 7 and 8 CPPRG (in press)
39
KEY QUESTIONS Does Fast Track Work? How Does It Work? Does It Work Equally Well for Everyone? How Much Does It Cost?
40
HOW DOES IT WORK? “ Domain-Specific ” Effects
41
MEDIATION OF GRADE 4 OUTCOMES CPPRG (2002d) Grade 3 Mediators Grade 4 Outcomes Home Parenting Behavior Change Aggressive/Oppositional Behavior School Authority Acceptance Peer Social Preference Problems/Prosocial Behavior Change Social Cognition Hostile Attributions Association with Substance Using Peers (p<.10)
42
HOW DOES IT WORK? “Domain-Specific” Effects Must Address Each Setting in Which the Child Lives Suggests Importance of Multicomponent Intervention
43
KEY QUESTIONS Does Fast Track Work? How Does It Work? Does It Work Equally Well for Everyone? How Much Does It Cost?
44
Works Comparably for: Boys and girls European- and African-American children Urban and rural communities DOES IT WORK EQUALLY WELL FOR EVERYONE? Elementary School
45
No Consistent Moderation by: Demographics - gender, race, site, cohort Child variables - IQ Family variables - marital status, SES, parent mental health/substance use Neighborhood variables - poverty, instability, quality
46
HOWEVER – By Grade 9, Effects Depend on Child ’ s Severity of Risk as Measured 10 Years Earlier During Kindergarten! DOES IT WORK EQUALLY WELL FOR EVERYONE? Antisocial Behavior
47
Highest-Risk Youth ( top 3% at Kindergarten ) Much Less Likely To: Have an externalizing disorder diagnosis - Oppositional defiant disorder, conduct disorder, attention deficit-hyperactivity disorder (ADHD) Engage in self-reported antisocial behavior No Intervention Effect for Moderate-Risk Youth DOES IT WORK EQUALLY WELL FOR EVERYONE? Antisocial Behavior in Grade 9 CPPRG, 2007
48
INTERVENTION EFFECTS Grade 9 DISC Diagnosis of Conduct Disorder (CPPRG, 2007) *p<.05 (Intervention x Risk Level) 0.04
49
INTERVENTION EFFECTS Grade 9 DISC Diagnosis of “Any” Externalizing Disorder (CPPRG, 2007) *p<.05 (Intervention x Risk Level) 0.13
50
INTERVENTION EFFECTS Grade 9 Self-Reported Antisocial Behavior (CPPRG, 2007) *p<.05 ( Intervention x Risk Level) 1.66
51
INTERVENTION EFFECTS Lifetime Prevalence of Conduct Disorder (through Grade 12) 0.12 CPPRG (in press)
52
YOUTH ARRESTS Court Record Data Collected Annually 6 th grade – age 19 Juvenile and adult court records Searched County of Residence and Surrounding Counties Lifetime Severity Weighted Frequency Juvenile arrests Adult arrests Self-reported delinquency CPPRG (in press)
53
ARREST RECORD OUTCOMES Juvenile Arrests Court-recorded: odds = 71% of odds for controls Moderate-severity arrests: 76% rate of controls Onset of arrest: odds = 77% of controls CPPRG (in press)
54
ARREST RECORD OUTCOMES High-Severity Self-reported Delinquent Behavior Onset: odds = 82% of controls High-Severity Adult Arrests Frequency: Highest-risk youth – 47% fewer arrests compared to controls Onset: Effects for ¾ sites; iatrogenic for Nashville CPPRG (in press)
55
KEY QUESTIONS Does Fast Track Work? How Does It Work? Does It Work Equally Well for Everyone? How Much Does It Cost?
56
HOW MUCH DOES IT COST? Each Chronic Criminal Costs Society >$1.3 Million (Cohen, 1998) Fast Track Costs About $5,800/Year Per Child ($58,000 Total) Cost-Effective for Highest-Risk Children (Top 10%) Conduct disorder diagnosis Index crimes Foster et al. (2006)
57
COST SAVINGS DUE TO INTERVENTION (PER CHILD) Low 90% Top 5-10% Top 5%
58
Parent and youth report (SACA; Grades 9-12) General Health ServicesOdds Ratio General health provider.77 Pediatrician.78 Emergency department.78 Gen health provider-Mental health.64 Mental Health Services Outpatient MH services (Gr 11-12).52 Inpatient MH services NS DOES FAST TRACK WORK? Health Services Use Grades 9-12 Jones et al (2010)
59
Modest Intervention Effects in Multiple Domains Through Elementary School Both high-risk and universal samples Effect sizes strongest following initial intensive prevention efforts Small to moderate effect sizes maintained with sustained prevention support In Contrast to Elementary School, Minimal Intervention Effects in Middle School SUMMARY
60
Mediation Analyses Indicate Domain- Specific Effects Suggests importance of multicomponent intervention Effects Generalizable Across Gender, Ethnicity, Site, Etc. During Elementary and Middle School SUMMARY (cont.)
61
However, During High School, Emerging Moderation of Effects Based on Severity of Initial Risk for Some Outcomes Strong Intervention Effects on Conduct Disorder Diagnosis Through Grade 12 for Highest-Risk Youth Strong Intervention Effect for Juvenile Arrests SUMMARY (cont.)
62
Although Expensive, Fast Track is Cost- Effective for Most At-Risk Youth Not Only in Terms of ↓ Dx of Externalizing Disorders, But ↓ Use of General Health and Outpatient MH Services During Adolescence (Jones et al., 2010) SUMMARY (cont.)
63
CURRENT/FUTURE DIRECTIONS Continued Analysis of Intervention Effects Through Age 20 Economic Analyses Analysis of DNA/Identification of Candidate Marker Genes Contact Sample at Age 25 Dissemination Efforts
64
CURRENT/FUTURE DIRECTIONS ARRA Admin Supplement (Witkiewitz) Developmental pathways of conduct problems Role of callous-unemotional traits as predictor of youth outcomes and/or moderator of FT intervention ARRA Challenge Grant (King, Witkiewitz) Identify Krueger’s “externalizing spectrum” in childhood and adolescence?
