Caring for someone with dementia can be demanding, particularly for spouses living with the care recipient. The main goal of this study was to clarify differences in the experience of caregivers who were husbands and wives with respect to burden, health, healthy behaviors, presence of difficult care recipient behaviors, social supports, and the quality of the premorbid relationship. The results of this study support research demonstrating a difference between the caregiving experiences of women and men. It is becoming increasingly apparent that female gender is a marker that places them at increased risk of high burden and less support.

Background: Alzheimer's disease (AD) is associated with dependence in activities of daily living (ADL). In addition to the cognitive impairment resulting from AD, the presence of psychotic symptoms may further increase this dependence. The objective of this study was to quantify the additional contribution of psychotic symptoms to dependence in ADL. Method: We analyzed data from 558 individuals with AD referred to a memory clinic. Information on ADL, psychotic symptoms, depression symptoms, and cognition was collected with standardized instruments. Results: The frequency of psychotic symptoms was correlated with dependence in ADL (r = −.44, p < .001). The independent contribution of psychotic symptoms to ADL (basic and instrumental) after consideration for cognitive impairment and depression symptoms was assessed with hierarchical regression models. Twenty-five percent of basic ADL variance was explained by cognition; psychotic symptoms accounted for an additional 7% of the variance (b = −0.12, p < .001). Cognitive impairment explained 31% of instrumental ADL variance; psychotic symptoms accounted for an additional 6% (b = −0.21, p < .001). Discussion: Psychotic symptoms are associated with dependence in ADL after controlling for cognitive impairment and depression symptoms. Future research should investigate possible causal linkages between psychotic symptoms and dependence in ADL. This may have implications regarding interventions to maintain independent living in people with AD.

Changes in psychotic symptoms may influence basic but not instrumental ADL over time. These findings may have ramifications for studies and treatment plans for individuals with AD who demonstrate psychotic symptoms.

An important distinction to make when assessing the impact of social media use on mental health is whether the use is passive (e.g., browsing) or active (e.g., posting). Recent research suggests that the connection between passive social media use and mental ill-being is inconsistent, with some research finding a significant negative association, while other research finds no such association. In the present research, we sought to investigate this relationship, as well as two potential moderators of this relationship: the subjective appraisal of social media content social media users consume (i.e., positively or negatively-appraised) and age of users. In a cross-sectional survey of Australian and United States Facebook users (N = 991), there was no direct relationship between passive use and mental ill-being, however user age and positive (but not negative) content appraisal were found to moderate the relationship between passive use and mental ill-being. Specifically, the relationship between passive use and mental ill-being became weaker as subjective positive appraisal increased, and it reversed to become negative at high levels of positive appraisal. Additionally, the positive relationship between passive use and mental ill-being became weaker as age of social media users increased, and the direction of this relationship became negative at the oldest ages of social media users. These results suggest that the relationship between social media use and mental ill-being is more nuanced than previous research suggests. In particular, higher amounts of passive Facebook use may have a less negative, or even a positive effect on social media users’ mental health when the content being (passively) consumed is positively appraised, or when users are older.
