OBJECTIVES. The objective of this work was to evaluate the reach, effective
ness, adoption, and implementation of a brief behavioral dietary interventi
on and 2 supplemental components of diabetes self-management support: telep
hone follow-up calls and community resources enhancement.
DESIGN AND SUBJECTS. This was a 2 x 2 randomized, controlled trial investig
ating the incremental effects of telephone follow-up and community resource
s enhancement with 320 adult type 2 diabetes outpatients.
METHODS. Key outcomes included behavioral (dietary patterns, fat intake), p
hysiologic (HbA(1C), lipids), and quality-of-life/patient satisfaction meas
ures and were collected at baseline and 3- and 6-month follow-up.
RESULTS. Despite high reach (76% patient participation), excellent adoption
(all 12 primary care practices approached participated), and good implemen
tation, there were few outcome differences among treatment conditions. Ther
e was significant improvement across conditions in most outcomes in each ca
tegory at both follow-ups.
CONCLUSIONS. A brief, computer-assisted, dietary goal-setting intervention
basic treatment condition was moderately successful in producing dietary im
provements but less so in producing biologic or quality-of-life outcomes. A
dditions of follow-up phone calls or a community resources enhancement comp
onent did not produce incremental improvements over this basic intervention
