To explore the latent categories and influencing factors of dyadic decision self-efficacy among stroke patients and their caregivers.
A cross-sectional survey involving 305 patient-caregiver pairs was conducted using standardised questionnaires. Latent profile analysis was used to identify dyadic self-efficacy categories and multinomial logistic regression was employed to analyse influencing factors.
The dyadic decision self-efficacy of stroke patients and their caregivers was classified into three categories: low common decision self-efficacy group (35.6%), patients' high decision self-efficacy and caregivers' moderate decision self-efficacy group (38.6%), and high common decision self-efficacy group (25.8%). Influencing factors included patients' education level, income and health literacy, as well as caregivers' education, caregiving duration and social support.
The levels of dyadic decision self-efficacy among stroke patients and their caregivers are heterogeneous. Clinicians can develop targeted interventions involving both patients and caregivers, based on the population's characteristics and influencing factors, to improve their dyadic decision self-efficacy.
This study was conducted and reported in accordance with the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) 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.
