Transcript Intervention research - King's College London

Intervention research
• Provides evidence to improve effectiveness of
interventions
• Provides evidence on problems addressed
• Provides evidence on processes that occur
during intervention
• Provide evidence on staff competence and
skills
• Provides evidence on organisation of
intervention/treatment service
Treatment outcomes measured
• Substance use – type, frequency and quantity
• Health – physical and psychological
• Social functioning – employment, housing
crime
Issues in treatment outcome research
• Clients report multiple drug use and multiple
problems
• Severity of drug use, type, duration and route
all have impact – affect what treatment is
offered and outcomes
• Treatment programmes deliver combination
of interventions
Risk and protective factors
One component shared by effective prevention
programmes is a focus on risk and protective
factors that influence drug use.
Risk and protective factors
One component shared by effective prevention
programmes is a focus on risk and protective
factors that influence drug use.
Protective factors
Protective factors are characteristics that decrease
an individual’s risk for a substance abuse
• Strong bonds with the family
• experience of parental monitoring
• parental involvement in the lives of young people
NIDA Prevention Principles
• Programmes should enhance protective
factors and reduce risk factors
• Prevention programmes should include a
parents’ or carers’ component
• family-focused prevention interventions have
greater impact than those for parents or
children only
Family strengthening strategies
• Project Family
• Strengthening Families Program
• Behavioural Parent Teaching
Project Family
• Conducted in two sites, Iowa and Washington
• Involves parent competency training sessions
• one or all of these sessions attended by
adolescents and parents together
Project Family: the evidence
• Positive effects on parents’ child management
practices (standard setting etc)
• improved resistance to peer pressure
• positive parenting effects were associated
with reductions in children problem
behaviours
Strengthening Families Programme
• Aimed to help substance-abusing parents
improve their parenting skills and reduce
children’s risk factors
• Involves parent training, children’s skills
training and family skills training with both
Strengthening Families: the evidence
• Strengthening Families’ 14-session version has been
tested mainly on high-risk families with primary school
children, the seven-session version as a universal
substance use prevention programme for secondary
school children, but both have been used in other
roles.
• For both there is evidence of improved family, parental
and child functioning and of a retardation in the uptake
of substance use and a reduction in its severity.
• For drinking in particular, the seven-session
programme is considered the most promising approach
available
Behavioural Parent Teaching
• Involves parents only , usually in small groups
led by skilled trainer
• encourage interaction with children through
positive play, rewards etc
Behavioural Parent Teaching: the
evidence
• At least 45 hours needed with high risk
families
• works best with young children
