Trajectories and predictors of stress and depressive symptoms in spousal and intimate partner cancer caregivers

PURPOSE

The objective of the study is to investigate trajectories of stress and depressive symptoms of spousal and intimate partner caregivers in the context of cancer. We also examined the patient-related predictors of caregiver stress and depression.

DESIGN

This is a longitudinal cohort study.

PARTICIPANTS

Patients diagnosed with cancers affecting the hepatobiliary and pancreatic system and their spousal or intimate partner caregivers were recruited at a large tertiary cancer center.

METHODS

The patients and caregivers were assessed for their level of stress, depressive symptoms, relationship quality, and quality of life at the time of the patients' diagnosis, every 2 months for 12 months and then at 18 months.

FINDINGS

One hundred and seventy-nine caregivers were included in the trajectory analyses. Amongst the 179 caregivers, 120 patient and caregiver dyads had complete data at baseline to 6-months. The majority of the spousal caregivers were female (84%) and the mean age was 57 years. 25% of caregivers reported high levels of chronic depressive symptoms. However, significant reductions were observed at 6 months. High and moderate levels of caregiver stress were also reported in 21% and 36% of caregivers, respectively. The caregivers who reported moderate levels of stress had a decrease in stress over time while those in the high stress group reported stable levels of stress over time. Caregivers' stress is predicted by the cancer patients' depressive symptoms but not patients' quality of life.

CONCLUSIONS

Caregivers who reported high levels of stress and depressive symptoms at patients' cancer diagnosis remain high even after the initial adjustment. A bidirectional relationship between the caregivers' stress and the patients' depressive symptoms was observed.

IMPLICATIONS

The development of dyadic interventions focusing on the patients' and caregivers' distress is warranted to decrease psychological morbidities of the dyad.

The Influence of Social Support on Dyadic Functioning and Mental Health Among Military Personnel During Postdeployment Reintegration

OBJECTIVES

Although many service members successfully cope with exposure to stress and traumatic experiences, others have symptoms of depression, posttraumatic stress disorder (PTSD), and anxiety; contextual factors may account for the variability in outcomes from these experiences. This work sought to understand mechanisms through which social support influences the mental health of service members and whether dyadic functioning mediates this relationship.

METHODS

We collected cross-sectional data as part of a larger study conducted in 2013; 321 military personnel who had at least 1 deployment were included in these analyses. Surveys were completed online; we collected data on demographic characteristics, social support, mental health measures (depression, PTSD, and anxiety), and dyadic functioning. We performed process modeling through mediation analysis.

RESULTS

The direct effects of social support on the mental health of military personnel were limited; however, across all types of support networks, greater social support was significantly associated with better dyadic functioning. Dyadic functioning mediated the relationships between social support and depression/PTSD only when social support came from nonmilitary friends or family; dyadic functioning mediated social support and anxiety only when support came from family. We found no indirect effects of support from military peers or military leaders.

CONCLUSION

Findings here highlight the need to continue to explore ways in which social support, particularly from family and nonmilitary-connected peers, can bolster healthy intimate partner relationships and, in turn, improve the well-being of military service members who are deployed.
