A systematic review and meta-analysis of randomized controlled trials
to determine if motivational interviewing leads to increased physical activity,
cardiorespiratory fitness or functional exercise capacity in people with chronic
health conditions. DATA SOURCES: Seven electronic databases (MEDLINE, PsychINFO, EMBASE, AMED, CINHAL, SPORTDiscus and the Cochrane Central Register of Controlled
trials) were searched from inception until January 2014.
TRIAL SELECTION: Two
reviewers independently examined publications for inclusion. Trials were included
if participants were adults (>18 years), had a chronic health condition, used
motivational interviewing as the intervention and examined physical activity,
cardiorespiratory fitness or functional exercise capacity. DATA EXTRACTION: Two
reviewers independently extracted data. Risk of bias within trials was assessed
using the Physiotherapy Evidence Database Scale.
DATA SYNTHESIS: Meta-analyses
were conducted with standardized mean differences and 95% confidence intervals
(CIs) were calculated. The Grades of Recommendation, Assessment, Development and
Evaluation approach was used to evaluate the quality of the evidence. RESULTS:
Eleven publications (of ten trials) were included. There was moderate level
evidence that motivational interviewing had a small effect in increasing physical
activity levels in people with chronic health conditions relative to comparison
groups (standardized mean differences = 0.19, 95% CI 0.06 to 0.32, p = 0.004).
Sensitivity analysis based on trials that confirmed treatment fidelity produced a
larger effect. No conclusive evidence was observed for cardiorespiratory fitness
or functional exercise capacity. CONCLUSION:
The addition of motivational
interviewing to usual care may lead to modest improvements in physical activity
for people with chronic health conditions.
