The objective was to characterize the relation between different sources of school-based social support (friends, peers, and teachers) and bereaved siblings' grief and grief-related growth and to examine whether nonparental sources of social support buffer the effects of low parent support on bereaved siblings. Families (N = 85) were recruited from cancer registries at 3 pediatric institutions 3-12 months after a child's death. Bereaved siblings were 8-18 years old (M = 12.39, SD = 2.65) and majority female (58%) and White (74%). During home visits, siblings reported their perceptions of social support from parental and nonparental sources using the Social Support Scale for Children, as well as grief and grief-related growth using the Hogan Sibling Inventory of Bereavement. Parent, friend, and teacher support were positively correlated with grief-related growth, whereas parent and peer support were negatively correlated with grief for adolescents. Teacher and friend support significantly moderated the association between parent support and grief such that teacher and friend support accentuated the positive effects of parent support. Friend and peer support moderated associations between parent support and grief/growth for adolescents but not children. School-based social support, namely from friends, peers, and teachers, appears to facilitate the adjustment of bereaved siblings. Findings suggest that bereaved siblings may benefit from enhanced support from teachers and friends regardless of age, with middle/high school students particularly benefitting from increased support from close friends and peers.

Objective  Inconsistent links between posttraumatic stress symptoms (PTS) and posttraumatic growth (PTG) in youth following a stressful life event have been observed in previous literature. Latent profile analysis (LPA) provides a novel approach to examine the heterogeneity of relations between these constructs.  Method  Participants were 435 youth (cancer group = 253; healthy comparisons = 182) and one parent. Children completed measures of PTS, PTG, and a life-events checklist. Parents reported on their own PTS and PTG. LPA was conducted to identify distinct adjustment classes.  Results  LPA revealed three profiles. The majority of youth (83%) fell into two resilient groups differing by levels of PTG. Several factors predicted youth’s profile membership.  Conclusions  PTS and PTG appear to be relatively independent constructs, and their relation is dependent on contextual factors. The majority of youth appear to be resilient, and even those who experience significant distress were able to find benefit.

Although parental distress and child distress have been linked in families of children with cancer, how these associations change over time is unknown. The present study examined how the amount of time elapsed since the child’s diagnosis moderates the associations between self-reported parent and child symptoms of depression, anxiety, and post-traumatic stress in 255 parent-child dyads. Time since diagnosis moderated the associations between parental symptoms and child-reported anxiety and post-traumatic stress. Dyads farther out from diagnosis exhibited stronger associations between parental and child symptoms. Findings suggest the importance of monitoring the psychological adjustment of parents and children over time.

Objective Identified patterns of connectedness in youth with cancer and demographically similar healthy peers. Method Participants included 153 youth with a history of cancer and 101 youth without a history of serious illness (8–19 years). Children completed measures of connectedness, posttraumatic stress symptoms (PTSS), and benefit-finding. Parents also reported on children’s PTSS. Results Latent profile analysis revealed four profiles: high connectedness (45%), low connectedness (6%), connectedness primarily to parents (40%), and connectedness primarily to peers (9%). These profiles did not differ by history of cancer. However, profiles differed on PTSS and benefit-finding. Children highly connected across domains displayed the lowest PTSS and highest benefit-finding, while those with the lowest connectedness had the highest PTSS, with moderate PTSS and benefit-finding for the parent and peer profiles. Conclusion Children with cancer demonstrate patterns of connectedness similar to their healthy peers. Findings support connectedness as a possible mechanism facilitating resilience and growth.

To identify trajectories of depression symptoms in mothers of children with cancer from diagnosis/relapse through 5 years and examine maternal factors at diagnosis/relapse predicting membership in these trajectories. Mothers (n = 327; Mage = 37.6 years, SD = 7.7 years; 85.9% White) reported depression symptoms near the time of their child's diagnosis/relapse and then again at 1-, 3-, and 5-years postdiagnosis/relapse. Mothers also reported perceived stress, coping (primary control, secondary control, and disengagement coping), and spirituality near the time of diagnosis. Latent class growth analysis was used to identify latent trajectories of depression symptoms, and a 3-step multinomial logistic regression tested covariate predictors of membership in the trajectories. Three trajectories were identified: "low depression symptoms" (63.3%), "moderate depression symptoms" (31.5%), and "high depression symptoms" (5.2%). Mothers who used more primary and secondary control coping were more likely to be in the low depression symptom trajectory as compared with the moderate (OR = 1.64, p = .024 and OR = 1.38, p = .013, respectively) or high trajectories (OR = 1.99, p = .008 and OR = 1.81, p = .001, respectively). Although mothers of children with cancer generally displayed improved mental health further from diagnosis, mothers with more depression symptoms after diagnosis/relapse displayed substantial stability in depression symptoms over the 5 years. Mothers of children with cancer may benefit from early screening of mental health and coping strategies, as well as interventions to bolster effective coping for those with elevated depression symptoms.
