Testing Scalable, IVR-supported Cancer Prevention Interventions in the Rural Alabama Black Belt (DIAL)

April 9, 2026 updated by: Dorothy Pekmezi, PhD, University of Alabama at Birmingham
This protocol involves a randomized controlled trial (N=240) to test the efficacy of the Deep south Active Lifestyle (DIAL intervention) telephone-based physical activity counseling intervention vs. a wait list condition. Assessments of MVPA and psychosocial variables will occur at baseline, 6, 12, and 18 months. Primary aim. Test the efficacy of DIAL intervention vs. wait list control. Hypotheses are that the participants receiving DIAL intervention will report significantly greater increases in MVPA (based on 7-Day Physical Activity Recalls, accelerometers) from baseline to 6 and 12 months than the wait list control arm. Exploratory Aims. Examine 1) Intervention effects on physical performance and psychosocial variables (anxiety, depression, fatigue, sleep disturbance; corroborate self report sleep improvements from pilot with accelerometry); 2) Changes in MVPA from 12-18 months to assess long term (6 months post-intervention) maintenance in the intervention arm and ascertain replicability of intervention effects in wait list control arm; 3) Intervention costs; 4) Potential mediators (social support from family, friends, CHAs, theoretical constructs directly targeted by the intervention) and moderators (education, neighborhood/environmental features) of treatment efficacy; 5) Potential barriers/ facilitators to widespread implementation of DIAL intervention in rural Black belt counties by Deep South Network for Cancer Control.

  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: DIAL intervention
Deep south Interactive voice response system Active Lifestyle (DIAL) intervention. Participants will receive 12 months of automated physical activity phone counseling. Participants will report their physical activity to the IVR system each day for 3 months, twice/week in months 3-6, and once/week in months 6-12 and receive progress feedback via IVR system, along with community health worker support.
12 months of automated telephone physical activity counseling with community health worker support
No Intervention: Wait List Control
The wait list control participants will be instructed to maintain their normal routine until completion of the 6-month assessments and then receive the same 12-month DIAL intervention. To maintain engagement, these participants will be involved in monthly lunch and learns, focus groups, etc on cancer topics other than PA (e.g., screening) during the wait period.
