A randomized clinical trial of a parent-focused social-cognitive processing intervention for caregivers of children undergoing hematopoetic stem cell transplantation.

Objective: Providing care to one's child during and after a hematopoietic stem cell transplant (HSCT) is a universally stressful experience, but few psychological interventions have been developed to reduce caregiver distress. The goal of this study was to test the efficacy of a brief cognitive-behavioral intervention delivered to primary caregivers.

Methods: Two hundred eighteen caregivers were assigned either best-practice psychosocial care (BPC) or a parent social-cognitive intervention program (P-SCIP). The 5 session P-SCIP was delivered during the HSCT hospitalization. Caregivers completed measures of distress, optimism, coping, and fear appraisals preintervention, 1, 6 months, and 1 year.

Results: P-SCIP reduced caregiver's distress significantly more than BPC between the pretransplant assessment (Time 1) and 1-month follow-up assessment (Time 2). P-SCIP had a stronger effect than BPC among caregivers who began the hospitalization reporting higher depression and anxiety, and among caregivers whose children developed graft-versus-host disease (GvHD). Long-term treatment effects of P-SCIP were seen in traumatic distress among caregivers who reported higher anxiety pretransplant as well as among caregivers whose children had GvHD at HSCT discharge.

Conclusions: Screening caregivers for elevations in pretransplant anxiety and targeting interventions specifically to these caregivers, as well as targeting caregivers to children who develop GvHD, may prove beneficial.
