Dyadic coping in couples experiencing mild cognitive impairment

Background The diagnosis of Mild Cognitive Impairment (MCI) can create stress for patients and their care partners (dyads). This study aimed to understand how dyadic coping (DC; how well couples feel they cope together in the face of a stressor) is related to the psychological health and overall well-being of couples coping with an MCI diagnosis. Additionally, this study attempted to characterize the impact of the HABIT Healthy Action to Benefit Independence & Thinking® program as a novel approach for improving DC. Methods We analyzed DC in 213 people with MCI (pwMCI) and 205 care partners using the Dyadic Coping Inventory (Bodenmann, 2005). We compared DC scores to outcome measures of psychological health and well-being. We also analyzed DC in a subset of 135 pwMCI and 138 care partners with 3-month post HABIT DC scores to look for evidence of change. Results pwMCI and care partner DC significantly affected their own perception of emotional functioning on other measures [quality of life (QoL) and mood for pwMCI and QoL, mood, anxiety, and sense of burden for care partners]. pwMCI DC also predicted care partner anxiety. In all cases, better DC predicted better emotional functioning. Care partner DC was also found to significantly relate to how they rated the pwMCI’s cognitive and daily functioning as well as the pwMCI’s adherence with a cognitive rehabilitation intervention. pwMCI and care partners with low baseline DC showed an increase in DC scores after completing HABIT, as did pwMCI in the medium baseline DC group. Care partners with medium baseline DC did not experience change post HABIT. High copers in both the pwMCI and care partner groups experienced a decline in DC, although scores remained average to above average. Conclusion These results suggest that DC is an important part of a couple’s psychological health and well-being in MCI. Care partner DC may be particularly important in how partners rate their loved one’s cognitive and functional status and how they respond to cognitive rehabilitation intervention. The HABIT program may also represent a novel way to improve DC for low and medium coping couples.
