To identify and evaluate the magnitude of the association between caregiver psychosocial factors and depressive symptoms among people with dementia.
Systematic review and meta-analysis.
A systematic review with meta-analysis used a random-effects model to estimate the effect size.
Medline, PsycINFO, CINAHL, Scopus and Embase databases were searched for peer-reviewed studies from inception to 25 November 2023.
The review included 88 articles, with 61 selected for meta-analysis. Seven caregiver psychosocial factors were determined for the meta-analysis: caregiver quality of life, distress, positive aspects of caregiving, depression, burden, quality of the relationship and anxiety.
This study suggested that depressive symptoms in people with dementia were associated with caregiver quality of life, distress, burden, depression and positive aspects of caregiving.
Recognising the association between caregiver psychosocial factors and depressive symptoms in people with dementia has essential nursing implications. Adopting family-centred care models and integrating respite care and psychological support for caregivers can help improve patient outcomes and overall dementia care.
This study highlights the association between caregiver psychosocial factors and depressive symptoms in people with dementia. Caregiver distress, burden and depression were linked to increased depressive symptoms in people with dementia, while caregiver quality of life and positive aspects of caregiving were associated with depressive symptoms in people with dementia. These findings underscore the need for tailored interventions to enhance dyadic health.
This systematic review and meta-analysis adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

To explore the association between psychological capital and psychological distress in stroke patient–spouse dyads and examine the mediating effect of relationship satisfaction in this association.
A population of 207 stroke patient-spouse dyads completed the Positive Psychological Capital Questionnaire, Quality of Relationship Index, and Kessler Psychological Distress Scale. A dyadic analysis was conducted using the actor-partner interdependence mediation model.
In stroke-affected couples, a noteworthy interaction exists between moderately elevated levels of psychological capital (p < 0.01). Patients exhibit significantly diminished psychological capital and heightened psychological distress compared to their spouses (t = −5.429, p < 0.001; t = 2.536, p < 0.05). Conversely, there is no significant variance in relationship satisfaction between patients and the partners (t = −0.920, p > 0.05). Patient relationship satisfaction acts as a mediator in the correlation between dyadic psychological capital and patient psychological distress (β = −0.020, p < 0.05; β = −0.011, p < 0.05). Similarly, spousal relationship satisfaction serves as a mediator in the connection between dyadic psychological capital and spousal psychological distress (β = −0.011, p < 0.05; β = −0.020, p < 0.05).
Psychological distress was reduced when psychological capital or relationship satisfaction in stroke dyads was promoted, and relationship satisfaction is an important mediator of the impact of psychological capital on psychological distress in the dyads. Healthcare providers should pay equal attention to spouses and implement dyadic psychological capital interventions centered on stroke couples to enhance relationship satisfaction and reduce psychological distress.
