Correction to: The effects of SmartCare© on neuro‑oncology family caregivers’ distress: a randomized controlled trial

Purpose Patients with primary malignant brain tumors have high symptom burden and commonly rely on family caregivers for practical and emotional support. This can lead to negative mental and physical consequences for caregivers. We investigated effectiveness of an 8-week nurse-led online needs-based support program (SmartCare © ) with and without online self-guided cognitive behavioral therapy (CBT) for depression compared to enhanced care as usual (ECAU) on depressive symptoms, caregiving-specific distress, anxiety, mastery, and burden. Methods Family caregivers scoring ≥ 6 on a depressive symptoms inventory were randomized to three groups: ECAU plus self-guided CBT and SmartCare © ; ECAU plus SmartCare © ; ECAU only. Primary outcomes (depressive symptoms; caregiving-specific distress) and secondary outcomes (anxiety, caregiver mastery, and caregiver burden) were assessed online. Intention to treat (ITT) and per protocol (PP) analyses of covariance corrected for baseline scores were performed for outcomes at 4 months. Results In total, 120 family caregivers participated. Accrual and CBT engagement were lower than expected, therefore intervention groups were combined ( n = 80) and compared to ECAU ( n = 40). For depressive symptoms, no statistically significant group differences were found. Caregiving-specific distress decreased in the intervention group compared with ECAU (ITT: p = 0.01, partial ɳ 2 = 0.08; PP: p = 0.02, partial ɳ 2 = 0.08). A trend towards improvement in mastery for the intervention group compared with ECAU was identified (ITT: p = 0.08, partial ɳ 2 = 0.04; PP: p = 0.07, partial ɳ 2 = 0.05). Conclusions SmartCare © , with or without self-guided CBT, reduced caregiving-specific distress with a trend towards improving mastery. SmartCare © has the potential to improve the lives of families coping with a brain tumor diagnosis. Trial registration number NCT02058745; 10 February 2014
