Motivation in Obesity Behavioral Program
Weight Loss Study Aim
The aim of this randomized pilot study was to examine whether the addition
of motivational interviewing strategies to a behavioral obesity intervention
enhances adherence and glucose control in older obese women with NIDDM.
Twenty-two older obese women (41 percent
black) with NIDDM were randomly assigned to 1) a standard 16-week group
behavioral weight-control program that provided instruction in diet, exercise,
and behavioral modification or 2) the same group behavioral program with
three individualized motivational interviewing sessions added.
Weight Loss Study Results
The motivational group attended significantly more group meetings (13.3
vs. 8.9), completed significantly more food diaries (15.2 vs. 10.1), and
recorded blood glucose significantly more often (46.0 vs. 32.2 days) than
the standard group. Further, participants in the motivational group had
significantly better glucose control post-treatment (9.8 vs. 10.8 percent).
Although both groups demonstrated significant weight loss, no differences
were apparent between groups.
Weight Loss Study Conclusions
These results suggest that augmenting a standard behavioral treatment
program for obese women with NIDDM with a motivational interviewing component
may significantly enhance adherence to program recommendations and glycemic
control. Preliminary data warrant further investigation with larger samples
and a longer follow-up.
