Outcomes (research)

Question 1

A 2010 meta-analysis of 119 studies found that < > percent of participants showed some
improvement as a result of MI, with < > percent gaining a small but meaningful effect and
< > percent gaining a moderate or strong level. When compared to other active
treatments such as 12-step and cognitive behavioral therapy (CBT), the MI interventions
took over < > fewer minutes of treatment on average yet produced equal effects

Answer 1

A 2010 meta-analysis of 119 studies found that <75> percent of participants showed some
improvement as a result of MI, with <50> percent gaining a small but meaningful effect and
<25> percent gaining a moderate or strong level. When compared to other active
treatments such as 12-step and cognitive behavioral therapy (CBT), the MI interventions
took over <100> fewer minutes of treatment on average yet produced equal effects

Question 2

• A 2005 review and meta-analysis of randomized controlled trials using MI as an
intervention demonstrated improvements in physical health, mental health, and
substance use; < > percent of the well-designed MI trials found significant positive effects
of MI for behavior change, indicating that MI is more effective than traditional
approaches.

Answer 2

• A 2005 review and meta-analysis of randomized controlled trials using MI as an
intervention demonstrated improvements in physical health, mental health, and
substance use; <80> percent of the well-designed MI trials found significant positive effects
of MI for behavior change, indicating that MI is more effective than traditional
approaches.

Question 3

A third meta-analysis of MI found that the effect size of MI was < > when the
recipients were predominantly from minority populations, compared with White nonHispanic Americans

recipients were predominantly from minority populations, compared with White nonHispanic Americans

Question 4

In a study of homeless, unemployed, and substance-dependent veterans wait-listed for
entry into a residential treatment program, significantly more participants entered the
program from the group that received an MI intervention (< > percent) than in the group
who received a standard intake interview (< > percent).

Answer 4

In a study of homeless, unemployed, and substance-dependent veterans wait-listed for
entry into a residential treatment program, significantly more participants entered the
program from the group that received an MI intervention (<95> percent) than in the group
who received a standard intake interview (<71> percent).

Question 5

In the Center for Social Innovation’s Phase I MI Simulator Study, participants identified
as direct service providers, advocates, and administrators (14 percent) working in mental
health (54 percent), addictions (27 percent), and housing or shelter (29 percent) settings.
Participants in all study conditions increased their use of MI. Prior to the study, < > percent had used MI with their clients. Following the study, all but one (< > percent) were actively using MI with clients.

Answer 5

In the Center for Social Innovation’s Phase I MI Simulator Study, participants identified
as direct service providers, advocates, and administrators (14 percent) working in mental
health (54 percent), addictions (27 percent), and housing or shelter (29 percent) settings.
Participants in all study conditions increased their use of MI. Prior to the study, <65>
percent had used MI with their clients. Following the study, all but one (<95> percent) were actively using MI with clients.
