Based on a paper by D.L. MacKenzie and G. Zajac, “What Works in Corrections: the Impact of
Correctional Interventions on Recidivism submitted to the U.S. National Academies of Science, 2014
REDUCING THE CRIMINAL ACTIVITIES OF OFFENDERS
OVERVIEW
Changes in correctional philosophy in the U.S.
Impact of changes
Evidence-based corrections
Improvement in quality of research
What Works to reduce recidivism
Fidelity and implementation
1975: LIPTON, MARTINSON AND WILKS STUDY FOR
NEW YORK CORRECTIONAL SYSTEM
What Works?
“(with) few and isolated exceptions the rehabilitative
efforts that have been reported so far have had no
appreciable effect on recidivism.“
(Martinson, 1974, p25)
WORK WAS WIDELY INTERPRETED AS:
“NOTHING WORKS”
MARTINSON AND COLLEAGUE’S CONCLUSIONS
Inadequate research designs and methods
Poorly implemented programs
Impossible to determine from the
existing data whether anything could
work!!!!!
TIMES WERE RIPE FOR CHANGE
Social upheavals
Civil rights, women’s rights, sexual freedom
War in Vietnam
Corrections: riots in prison, unfairness of the system
Dramatic change in U.S. corrections
Move away from rehabilitation
More punitive, law and order and get tough
Deterrence and incapacitation
CHANGES IN PHILOSOPHY OF
CORRECTIONS
Impact on correctional system
and
What was studied
IMPACT ON CORRECTIONAL SYSTEM
Move away from
rehabilitation,
“Nothing
Works”
Use of
incapacitation
and deterrence
Law and order
philosophy
U.S. Incarceration Rate in
State and Federal Institutions
CHANGES SINCE MARTINSON’S REPORT
Corrections philosophy
Evidence-based corrections
Improvement in quality of research
Emphasis on implementation
CHANGES IN PHILOSOPHY
More punitive
Law and order
Incapacitation
Deterrence
PROGRAMS/ INTERVENTIONS
Correctional boot camps
Longer prison sentences
More prison sentences
Urine testing
Intensive supervision
EVIDENCE-BASED CORRECTIONS
Use of science in decision making
Identify effective correctional programs,
interventions, strategies
Correctional interventions should be those shown
in scientific studies to have the desired impact
WHAT WORKS IN CORRECTIONS?
What have we learned from
the research?
Focus on reducing recidivism
Examined management
strategies, programs,
interventions, treatment
DETERMINING WHAT WORKS
Maryland Report assessments
Quality of research
Significance and direction of effects
Meta-analyses
MARYLAND CRIME PREVENTION
REPORT
Requested by U.S. Congress
Comprehensive evaluation of effectiveness crime
prevention efforts (including corrections)
“What Works, What Doesn’t, What’s Promising”

QUALITY OF RESEARCH
Many more experiments (random assignment) since Martinson’s
report
Experiments with offending outcomes
35 from 1957-1981 (Farrington)
83 from 1982-2002 (Farrington and Welsh)
Most meta-analyses control for quality of research
Some meta-analyses use only randomized trials
IMPROVEMENT BUT STILL RELATIVELY FEW
RANDOMIZED TRIALS
284 Studies at scientific method score of 2 or
higher
Only 14.8 % of the studies scored “5”
23.2 % scored “2” – too low to use to
determine “What Works”
USING META-ANALYSES TO DETERMINE WHAT WORKS
Comprehensive or theoretical meta-analyses
Large number of studies
More inclusive in eligibility criteria
Support for various theoretical perspectives
Identify general principles of treatment and effectiveness
Intervention-specific meta-analyses
Focus on specific types of programs, strategies or interventions
Clearly define
Does the particular type of intervention reduce recidivism?
Campbell Collaboration
COMPREHENSIVE META-ANALYSES OF
CORRECTION INTERVENTIONS
Programs that follow the proposed principles (Andrews and Bonta 2006) are more
effective than others
Behavioral, skill-oriented or multimodal programs are more effective than other types of
programs (Andrews, Bonta, Gendreau, Lipsey 1992, Losel 1995)
Therapeutic rehabilitation programs more effective than punitive approaches (control
and deterrence) (Lipsey and Cullen 2007; Lipsey 2009)
Programs targeting high risk offenders are more effective (Lipsey 2009)
Well implemented programs are more effective (Lipsey 2009)
INTERVENTION-SPECIFIC ASSESSMENTS

Drug treatment in community and

INTERVENTIONS USING “GET TOUGH” OR “LAW

Surveillance and control
Deterrence and punitive
Discipline
WHY AREN’T PROGRAMS THAT INCREASE
SERVICES AND OPPORTUNITIES EFFECTIVE?
Offenders are not prepared to take advantage
Don’t stop “street life, alcohol/drug use or partying
Don’t get up to make it to work on time
May not get along with others at work
INDIVIDUAL TRANSFORMATION
Offenders must be changed before they are prepared to
take advantage of opportunities in the environment
Individual
Differences
•Attitudes
•Thoughts
•Feelings,
Environmental
Opportunities
•Available
housing
•Employment
•Poverty
(Giordano and colleagues, Maruna, Shover, Farrall)
Behavior
•Criminal
activities
•Prosocial
activities
WE’VE COME A LONG WAY SINCE
MARTINSON
Some programs do work
New and better research techniques
GOOD NEWS
Some interventions/programs work
Increased number of experiments
Emphasis on evidence-based
corrections
BAD NEWS
Many programs/ interventions implemented under “law &
order” emphasis have been shown to be ineffective
Quality of research
Long way to go to reach other fields in number of
experiments
Meta-analyses search through thousands of studies
to find level 3 or above
Fidelity and Implementation still an issue
