Cognitive Abilities and Collaboration in Couples in Type 1 Diabetes Management

Area of Science:

• Psychology
• Endocrinology
• Gerontology

Background:

• Type 1 diabetes (T1D) management requires complex daily behaviors.
• Cognitive abilities of both individuals with diabetes (PWD) and their spouses play a role in collaborative diabetes care.
• Understanding the interplay of cognitive function and spousal support is crucial for T1D management.

Purpose of the Study:

• To investigate if cognitive abilities of PWD and their spouses predict lower A1C.
• To determine if spousal cognitive ability benefits PWD with lower cognitive function, especially through collaboration.
• To examine if these cognitive benefits are mediated by improved self-care behaviors.

Main Methods:

• 199 couples (one with T1D) were recruited.
• Fluid and crystallized cognitive abilities were assessed using standardized tests (Delis-Kaplan Executive Function System, Wechsler Adult Intelligence Scale-4th Edition).
• Spousal collaboration, PWD self-care, and A1C levels were measured via surveys and blood assays.

Main Results:

• Spouses' crystallized cognitive ability significantly predicted lower A1C.
• An interaction effect showed that PWD with lower cognitive ability benefited more from collaborating with spouses who had higher cognitive ability.
• Spousal crystallized ability improved PWD's self-care behaviors, which in turn was associated with lower A1C.

Conclusions:

• Cognitive abilities of spouses are valuable assets in managing type 1 diabetes.
• Spousal crystallized intelligence positively impacts T1D management by enhancing PWD's self-care behaviors.
• Interventions supporting spousal involvement and leveraging their cognitive strengths may improve glycemic control in PWD.
