>> An interagency workgroup has
been convened to use evidence
to make a decision
about implementing a youth
suicide prevention strategy
in their community that
strengthens social, emotional,
and behavioral skills
of high risk youth
and provides support
to their parents.
SAMHSA's National Registry
of Evidence-Based Programs
and Practices was an excellent
resource for the work group
to use to gain an understanding
of the best available
research evidence
on youth suicide prevention.
The SAMHSA registry included
studies and systematic reviews
of youth-oriented
prevention programs.
>> A review is simply, you
know, somebody like me goes
to the scientific literature
and tries to find every study
on a particular thing, maybe
it's parent training programs.
A systematic review
is really just doing
that in a very systematic
way, meaning that we're going
to have a particular
set of search terms,
we're going to search a
particular set of years.
When we code the studies --
and this is very important --
we're going to code
them in a particular way
with a very clear set of rules
for inclusion and exclusion
and how we're going
to classify things.
>> Best available research
evidence and the continuum
of evidence of effectiveness.
The purpose of the continuum
is to present a clear set
of standards on best available
research evidence for the field
of violence prevention, provide
information for decision-making,
and provide a common language
for understanding the best
available research evidence.
The continuum is designed
to be used as a tool
to help researchers,
practitioners,
and policymakers better
understand best available
research evidence and why
this evidence is important.
The continuum is not a tool
for classifying violence
prevention programs,
such as attaching an overarching
label to a program such as
"supported"; for example,
a program may are a
quasi-experimental research
design but offer no
implementation guidance.
In this example the research
design and internal validity
of this program would
be considered supported
but its implementation
guidance would be undetermined.
Overview of best
available research evidence.
Best available research evidence
has been the primary form
of evidence used in most
science-based fields including
public health.
The strength of the
research evidence varies
across different
fields and topic areas,
and not all of the dimensions
we covered have been considered.
It is important to note how the
strength of the evidence varies
across each dimension
of the continuum.
It is also important to
consider other factors
that influence evidence-based
decision-making
such as contextual and
experiential fact --
