EVALUATING
THE EFFECTIVENESS OF THE INCREDIBLE YEARS INTERVENTIONS
FOR YOUNG CHILDREN WITH ADHD
Funded
by NIMH 2005-2010

Preschool
symptoms of attention deficit hyperactivity disorder (ADHD)
mark significant risk for the development of oppositional
defiant disorder (ODD) and early-onset conduct disorder
(CD). Children with ADHD often struggle in school, have
difficulty forming positive peer relationships, and may
be oppositional with their parents and teachers. Without
intervention, many of these children may go on to have more
serious problems such as bullying, school drop out, delinquency,
substance dependences, and interpersonal violence. Early
intervention can help to prevent these later problems, and
is advisable since interventions become increasingly less
effective and more expensive if delayed until late childhood
or adolescence.
The
most effective means of preventing CD may be to target preschool
children with ADHD and/or ODD, before more serious conduct
problems have escalated. Unfortunately, one limitation of
the ADHD treatment-outcome literature is that very little
research has been conducted with preschool samples. In this
study we will examine the effectiveness of a comprehensive
treatment program (aka Incredible Years Training Series)
for children ages 4-6 years, which includes a group-based
parenting program, a child social skills and problem solving
small group treatment program and teacher consultation and
support. In the proposed research, groups of children with
ADHD will be assigned randomly to the above treatment condition,
or a delayed treatment condition. The delayed group will
wait 6 months and then the children will participate in
an intensive social skills summer camp based on the Incredible
Years Dinosaur School. At pre-treatment, post-treatment,
and one- and two-year follow-ups, extensive assessment batteries
will be administered to evaluate family relations, peer
relations, school adjustment, and physiological functioning
among ADHD participants, and among a group of typically
developing children.
This
design will enable us to address several unanswered questions
regarding the treatment responsiveness, developmental progression,
and biological substrates of early-onset ADHD and conduct
problems. The study will be the first to (a) test whether
a well established intervention for ODD and CD is effective
in preventing conduct problems in high-risk preschoolers
with ADHD, (b) assess pretreatment biological markers of
intervention outcome, (c) examine interactions between biological
and environmental risk for developing CD, and, (d) examine
potential differences in CD outcomes for ADHD preschoolers
with and without comorbid ODD.

IMPROVING
THERAPIST FIDELITY DURING EVIDENCE-BASED PRACTICE (EBP)
IMPLEMENTATION

Aim
1: To evaluate the effectiveness of the IY parent program
for treating child conduct problems in an ethnically diverse
TANF population compared to usual services (CONTROL).
Aim
2: To evaluate the additional contribution to child and
family outcomes of the enhanced relative to the standard
model (EIM vs. SIM) for implementing the IY parenting program.
Aim
3: To evaluate the relationship between treatment fidelity
and child and family outcomes, and to estimate the additional
contribution to intervention fidelity of the EIM relative
to the SIM condition.
Improving
our understanding of factors that influence the fidelity
and effective implementation of evidence-based practices
(EBP) is an important national health care priority. Research
suggests that fidelity is compromised when interventions
are transported from the research laboratory to "real
world" settings. The Incredible Years (IY) parenting
program is a model EBP program that has repeatedly been
shown to be effective in treating children's conduct problems
in randomized control group trials. This program has been
selected for study because an independent APA review board
reported that it was one of only two empirically validated
treatments available for young children with conduct problems.
However, little is known about its transportability to community
mental health systems or the fidelity with which it is delivered
by therapists in these settings. The aim of the current
study is to experimentally test two IY implementation models
for achieving treatment fidelity and positive child and
parent outcomes. Finding effective implementation models
to successfully treat early onset conduct problems is a
major public health concern because this disorder is highly
predictive of long-term antisocial behavior, including delinquency,
drug abuse, and violence.
Ultimately,
effective implementation of an EBP intervention in community
mental health settings depends upon therapists learning
the program and delivering it with adherence to the content
and with competence in the therapeutic methods and processes.
Even for well developed interventions, such as the IY, which
has well developed training materials and a documented training
procedure, high fidelity implementation may require more
intensive efforts. Key factors hypothesized to affect implementation
effectiveness (i.e., fidelity) include delivery of all
program content, adequate organizational supports
for therapists, attention to the fit between the
values of the program and those of the organization and
therapists, and development of therapist skills and
commitment to implement the program with fidelity.
This
randomized, controlled trial compares two models for implementing
the IY treatment program with a usual care control condition.
Organizations delivering the program under the Standard
Implementation Model (SIM) will receive detailed IY materials
and will participate in one-time intensive training. The
Enhanced Implementation Model (EIM) includes all elements
of SIM plus organizational support, promotion of the
fit between therapist and organizational values and the
IY program, and ongoing training, technical support,
and consultation.
This
study will test these two IY implementation models in a
sample of 720 children with conduct problems whose families
are receiving Temporary Assistance for Needy Families (TANF)
in California. Many children in this population will be
at very high-risk for current or future conduct problems
because they are living in poverty. Two-thirds of families
selected for the study will be randomly assigned to participate
in the IY parenting program, paid for by Medicaid, while
1/3 will be followed naturalistically with normal TANF services
(CONTROL). Among families participating in the IY conditions,
half will receive these services from therapists in an agency
randomized to SIM. The other half will receive services
from therapists in an agency randomized to EIM. Both implementation
models proposed in this study fit within the constraints
faced by "real world" agencies, reducing the intensity
of control and supervision utilized in prior efficacy studies
but taking advantage of a range of technology to mimic those
controls in a more cost-effective manner.
