This report presents the results of a study to examine the feasibility
of using volunteers as research staff for a randomized trial of wheth
er reduction in dietary fat intake could prevent or delay breast cance
r recurrence, We examined whether volunteers could be trained to recru
it study participants, deliver a complex and intensive dietary interve
ntion, and monitor intervention effectiveness, Volunteers, who were mo
stly employed nurses and dietitians, screened 521 women, of whom 293 w
ere eligible and 144 were randomized, Participants were postmenopausal
women under age 75, who had recently been diagnosed with breast cance
r and treated with either mastectomy or lumpectomy, At 1 year postrand
omization, 77% of intervention and 75% of control participants remaine
d active in the study, Intervention effects (change in intervention gr
oup minus change in control group) at 3, 6, and 12 months postrandomiz
ation were 5.9, 8.4, and 7.2% energy from fat and 1.7, 3.0, and 3.5 kg
body weight (all P < 0.001), These results were similar to those from
other studies that used paid, professional staff to deliver and monit
or interventions, Results from this feasibility study suggest that vol
unteer-based health organizations can provide research opportunities f
or health practitioners and can conduct high-quality research at lower
costs.
