Group-Based Trajectory Modeling of Distress and Well-Being Among Caregivers of Children Undergoing Hematopoetic Stem Cell Transplant

Objective: To examine the trajectories of caregiver psychological responses in the year following their child's hematopoetic stem cell transplant (HSCT), and whether cognitive and social processing strategies differentiated between trajectories. Method: One hundred and eight caregivers randomized to the control condition of a cognitive-behavioral intervention study completed measures of distress, coping, and social support at baseline, 1 month, 6 months, and 1 year post HSCT of their child. Results: The majority reported moderate or low anxiety, depression, or distress that decreased over time, but a small group demonstrated high anxiety, depression, or distress that persisted or increased over time. Maladaptive coping was highest among caregivers in the high-persistent distress subgroup compared with the moderate-decreasing and low-stable groups. Adaptive coping was minimally associated with trajectory subgroups. Conclusions: Screening HSCT caregivers for distress and maladaptive coping may be useful in identifying caregivers likely to experience persistently high distress who may benefit from psychological intervention.
