Factors associated with psychological distress in caregivers of patients with malignant gliomas.

PURPOSE

Caregivers of patients with malignant gliomas are at risk for psychological distress. However, factors associated with distress in this population have not been well described. We conducted a prospective study evaluating psychological distress in patients with malignant gliomas and their caregivers and exploring factors associated with caregiver distress.

METHODS

We enrolled patients with newly diagnosed malignant gliomas (N = 77) and their caregivers (N = 61). At baseline and 3, 6, and 9 months after diagnosis, we administered the Hospital Anxiety and Depression Scale to assess psychological distress and the Caregiver Reaction Assessment to evaluate caregiver burden. We performed multivariable regression analyses to investigate caregiver-related, patient-related, and tumor-related factors associated with caregivers' distress.

RESULTS

At baseline, 48.3% (29/60) and 26.2% (16/61) of caregivers reported clinically significant anxiety and depression symptoms, respectively. Anxiety and depression symptoms persisted over time. Greater caregiver depression was associated with male gender (B = 1.48, 95% CI 0.16-2.81, p = 0.03), higher caregiver burden (B = 0.08, 95% CI 0.01-0.15, p = 0.02), caregiver anxiety (B = 0.53, 95% CI 0.38-0.68, p < 0.0001), patient depression (B = 0.34, 95% CI 0.13-0.55, p = 0.002), and caring for a younger patient (B =  -0.07, 95% CI -0.15 to 0.00, p = 0.049). Factors associated with greater caregiver anxiety symptoms were caregiver depression (B = 0.91, 95% CI 0.71-1.12, p < 0.0001) and younger patient age (B =  -0.15, 95% CI -0.24 to -0.05, p = 0.003).

CONCLUSION

Male gender, higher caregiver burden, greater patient depression symptoms, and younger patient age are associated with increased distress among caregivers of patients with malignant gliomas, underscoring the need for tailored supportive care interventions targeting caregivers at highest risk for psychological distress.
