A Couple-Based Intervention for Chinese Older Adults With Type 2 Diabetes: A Randomized Clinical Trial

These findings show that the overall treatment effect of the couple-based intervention was weak. However, the couple-based intervention benefited patients with poor glucose control. Patients' glucose levels, spouses' availability to provide support, and couples' collaborative preferences for mutual or individual diabetes management should be considered in tailoring treatment strategies among older adults with type 2 diabetes.

Secondary outcomes
Collective efficacy and collective behavior
- Increased in patients after intervention, similar magnitude between arms; no between-arm differences among spouses
Hemoglobin A1c (HbA1c), subgroup with baseline HbA1c ≥8.0%
- Decreases in HbA1c constant and lasting, statistically significant difference
