Helping couples communicate better to improve step-count prescriptions for people with type 2 diabetes

A Dyadic Coping Strategy to Enhance Step Prescription Effects in Type 2 Diabetes: a Bayesian Adaptive Basket Randomized Controlled Trial

Not applicable Interventional McGill University Health Centre/Research Institute of the McGill University Health Centre · NCT07142512

This project will test whether teaching couples better ways to communicate, alongside giving both partners step-count prescriptions, helps people with type 2 diabetes walk more.

What this trial studies

The trial enrolls people with type 2 diabetes who live with a partner to compare two approaches for increasing daily steps. All participants and their partners receive step counters and a SMARTER step-prescription program; half the couples are randomized to also receive a dyadic coping (communication) intervention. Investigators will track step counts over time, collect baseline and follow-up measures, and record a couple conversation to analyze communication styles. Eligible participants are age 45 or older, cohabiting for at least two years, able to walk, and must have smartphone and internet access; the trial is conducted at McGill-affiliated hospitals in Montreal.

Who should consider this trial

Good fit: Ideal candidates are adults 45 or older with type 2 diabetes who live with a partner for two or more years, can walk without major impairment, and have a smartphone and internet access.

Not a fit: People without a cohabiting partner, those with gait-limiting conditions, those unwilling to record couple conversations, or those without smartphone/internet access are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the combined approach could help people with type 2 diabetes increase daily walking, improving blood sugar control and cardiovascular health.

How similar studies have performed: Previous trials of the SMARTER step-prescription approach have increased physical activity, but adding a structured dyadic coping communication intervention to step prescriptions is relatively new.
