Personal growth and cognitive complexity in caregivers of patients with dementia.

According to several theoretical models, crises or demands can result in enhanced cognitive maturity. Two studies examined whether demands on caregivers provide an opportunity to experience increased cognitive maturity (e.g., cognitive complexity, personal growth through caregiving). In Study 1 (126 relatives of dementia patients; cross-sectional design), personal growth through caregiving was associated with two specific caregiving demands: duration of caregiving and lack of social acknowledgment. Cognitive complexity correlated with duration of caregiving and crystallized intelligence. The caregivers in the second study ( = 321) were participants in LEANDER, The Longitudinal Dementia Caregiver Stress Study. Caregivers were examined in four waves over 27 months. The results indicated an increase in personal growth over time. Using latent growth models, we found that increases in personal growth through caregiving were predicted by increases in the objective caregiving tasks. Cognitive processes (e.g., ruminative thoughts, life reflection) provide a possible explanation for an increase in cognitive maturity.
