Quality of life of caregivers at the end of their child's pediatric cancer treatment: cancer-specific worry and material hardship

OBJECTIVE

Emerging research suggests that completion of pediatric cancer treatment can be challenging for caregivers given shifting roles and responsibilities. Lower caregiver quality of life (QOL) has been associated with cancer-related variables, higher cancer caregiving strain, and more household material hardship during pediatric cancer treatment. Caregiver QOL at the end of treatment has not been fully investigated but has implications for child and family well-being. Using a psycho-oncology framework, this study aimed to understand the cumulative burden of household material hardship and cancer-related factors on caregiver QOL at the end of treatment.

METHODS

Caregivers (N = 143) of children (Mage=10.51 years) within 1 year of ending active cancer treatment completed self-report questionnaires assessing their QOL, cancer-specific worry, and material hardship (e.g., housing, insurance). Total months of active cancer treatment were extracted from the medical record. Hierarchical linear regression was used to test the relative effects of length of treatment, material hardship, and cancer-specific worry on caregiver QOL.

RESULTS

Cancer-specific worry was significantly associated with and accounted for significant variance in caregiver QOL, above and beyond the length of treatment and material hardship. Caregivers who endorsed more cancer-specific worry had poorer QOL. Material hardship was also significantly associated with caregivers' QOL, but length of treatment was not.

CONCLUSIONS

Caregivers with sufficient resources and less worry about cancer have higher QOL. Findings highlight the importance of end-of-treatment screening of caregivers' subjective cancer-specific worry in addition to material hardship, irrespective of their cancer-related stressors, for ongoing psychosocial support.

Caregiver condition management and family functioning after pediatric cancer treatment: Moderation by race and ethnicity

OBJECTIVE

End of pediatric cancer treatment requires family adjustment. Caregivers who struggle to incorporate the child's condition into family life have poorer family outcomes. To better understand factors that contribute to successful transition off active childhood cancer treatment, we sought to examine caregiver perceived management ability of the youth's condition and family functioning as predictors of caregiver distress, evaluate family functioning as a mediator between perceived ability and distress, and explore race and ethnicity as a moderator between perceived ability and family functioning.

METHODS

Caregivers (N = 141) completed measures assessing family management (condition management ability; CMA), family functioning, and distress as part of a clinical education and screening program within 1 year of the end of treatment. Bias-corrected bootstrap regression analyses examined mediation and moderated mediation models with patient race and ethnicity as the moderator.

RESULTS

The overall mediation model was statistically significant for CMA→family functioning→distress. Race and ethnicity moderated the relationship between CMA and family functioning, but the full model was not significant. CMA was related to family functioning for caregivers of non-Hispanic white youth, but not caregivers of Hispanic youth. Family functioning was related to distress for all caregivers.

CONCLUSIONS

Family functioning serves as an initial intervention target to reduce caregiver distress. Caregiver perceived management ability of their child's condition is a meaningful predictor of family functioning and distress for caregivers of non-Hispanic white youth, yet CMA may be limited as a screener of family management patterns for diverse populations, and other family management dimension may be more applicable.

Psychosocial needs of pediatric cancer patients and their caregivers at end of treatment: Why psychosocial screening remains important

OBJECTIVE

The pediatric cancer Psychosocial Standards of Care calls for psychosocial screening across the cancer trajectory. The current study aims to describe pediatric cancer family needs at the end of treatment (EOT) and summarize feedback on a clinical EOT screening and education program.

METHODS

During a clinic visit, families attended an education session regarding general EOT considerations and caregivers and youth aged 11+ years completed questionnaires. Scores were coded for clinical significance based on cutoff scores per questionnaire, and clinical significance frequencies were calculated. Caregivers provided qualitative feedback on the EOT program via an open-ended prompt.

RESULTS

Screening was completed by 151 families. Ninety-four patients (67.1%) endorsed risk by self- or proxy-report in at least one domain. Across all patient age groups, a symptom of neurocognitive functioning was the most frequently endorsed risk, including executive functioning, sustained focused, and thinking slower than others. For caregivers, 106 (74.1%) endorsed risk in at least one domain, with concerns for ability to manage their child's medical condition as the most frequent endorsement. Families were agreeable to an EOT program with many caregivers advocating for receiving this program earlier.

CONCLUSIONS

Both patients and caregivers experienced clinically significant needs that require intervention at EOT. While patients are experiencing neurocognitive effects and distress, their caregivers are balancing management of their own distress with management of their child's needs during a transition to decreased support from the medical team. The findings affirm the need for systematic screening at EOT and anticipatory guidance for off treatment expectations.

Adherence and Barriers to Inpatient Physical Therapy Among Adolescents and Young Adults with Hematologic Malignancies

This study described inpatient physical therapy (PT) adherence and barriers to inpatient PT among adolescents and young adults (AYAs) with hematologic malignancies receiving care at a Midwestern children's hospital. Forty-seven AYAs receiving care over a 2-year period were included. PT contact was established in 93% of hospitalizations. AYAs declined an average of 34% of PT visits, resulting in PT visits on 27% of hospitalized days, 1 day less than the goal of 3 days a week. The most frequent reasons for decline included: AYA sleeping (22%), AYA undergoing medical procedure (18%), and AYA not feeling well (12%).

Health-Related Quality of Life at Diagnosis for Pediatric Thyroid Cancer Patients

CONTEXT

Pediatric thyroid cancer (TC) incidence rates are increasing, yet TC has one of the highest survival rates. Despite increased prevalence, little is known about youth adjustment to TC, particularly compared to other pediatric cancers.

OBJECTIVE

The current study sought to describe health-related quality of life (HRQoL) in pediatric TC patients early after diagnosis compared to other pediatric cancer patients and healthy youth and examine predictors of HRQoL.

DESIGN

Patients completed psychosocial questionnaires as part of a clinic-based screening program around time of surgery. TC HRQoL was compared to other pediatric cancer and healthy youth reported norms. Clinical and demographic data extracted from the medical record were examined for predictors of HRQoL.

SETTING

Pediatric Thyroid Center.

PATIENTS AND OTHER PARTICIPANTS

Pediatric TC patients (ages 8.5-23.4 years) and their caregivers.

MAIN OUTCOME MEASURES

Pediatric Quality of Life Inventory (HRQoL) and distress thermometer.

RESULTS

Findings evidenced significantly higher HRQoL for TC patients than other pediatric cancers for all but emotional and school functioning. Compared to healthy youth, TC patients reported significantly lower functioning, except comparable social functioning. No significant differences in HRQoL were identified based on disease severity, thyroid disease history, or treatment. Patient distress was associated with HRQoL.

CONCLUSIONS

The findings suggest general resilience in TC patients compared to youth with other cancers, yet worse HRQoL than peers. Early universal screening is warranted due to a short TC treatment regimen. If administrative barriers preclude comprehensive screening, the single-item distress thermometer may identify patients for further comprehensive screening.

Health Care Utilization, Transition Readiness, and Quality of Life: A Latent Class Analysis

OBJECTIVE

To identify possible subgroups of health care utilization (HCU) patterns among adolescents and young adults (AYAs) with a chronic medical condition (CMC), and examine how these patterns relate to transition readiness and health-related quality of life (HRQoL).

METHODS

Undergraduates (N = 359; Mage=19.51 years, SD = 1.31) with a self-reported CMC (e.g., asthma, allergies, irritable bowel syndrome) completed measures of demographics, HCU (e.g., presence of specialty or adult providers, recent medical visits), transition readiness, and mental HRQoL (MHC) and physical HRQoL (PHC). Latent class analysis identified four distinct patterns of HCU. The BCH procedure evaluated how these patterns related to transition readiness and HRQoL outcomes.

RESULTS

Based on seven indicators of HCU, a four-class model was found to have optimal fit. Classes were termed High Utilization (n = 95), Adult Primary Care Physician (PCP)-Moderate Utilization (n = 107), Family PCP-Moderate Utilization (n = 81), and Low Utilization (n = 76). Age, family income, and illness controllability predicted class membership. Class membership predicted transition readiness and PHC, but not MHC. The High Utilization group reported the highest transition readiness and the lowest HRQoL, while the Low Utilization group reported the lowest transition readiness and highest HRQoL.

CONCLUSIONS

The present study characterizes the varying degrees to which AYAs with CMCs utilize health care. Our findings suggest poorer PHC may result in higher HCU, and that greater skills and health care engagement may not be sufficient for optimizing HRQoL. Future research should examine the High Utilization subgroup and their risk for poorer HRQoL.

Illness Uncertainty Longitudinally Predicts Distress Among Caregivers of Children Born With DSD

OBJECTIVE

A subset of parents of children with disorders/differences of sex development (DSD) including ambiguous genitalia experience clinically elevated levels of anxious and depressive symptoms. Research indicates that uncertainty about their child's DSD is associated with parent psychosocial distress; however, previous studies have been cross-sectional or correlational in nature. The current study is the first to examine the longitudinal trajectory of the relationship between caregiver-perceived uncertainty about their child's DSD and caregiver anxious and depressive symptoms across the first 12 months following genital surgery in young children, or if surgery was not performed, the first 12 months following study entry.

METHODS

One hundred and thirteen caregivers (Mage = 32.12; 57.5% mothers; 72.6% Caucasian) of children (N = 70; Mage = 9.81 months; 65.7% female) with DSD were recruited from 12 DSD specialty clinics in the United States. Caregivers completed psychosocial measures at baseline, 6 and 12 months following genitoplasty, or study entry if parents elected not to have surgery for their child.

RESULTS

Caregiver illness uncertainty and both anxious and depressive symptoms were highest at baseline and decreased over time (ps < .05). Caregiver illness uncertainty predicted symptoms of anxious and depressive symptoms across all time points (ps < .05).

CONCLUSIONS

Caregivers' perceptions of uncertainty about their child's DSD are highest soon after diagnosis, and uncertainty continues to predict both anxious and depressive symptoms across time. Thus, the initial diagnostic period is a critical time for psychological assessment and intervention, with parent illness uncertainty being an important clinical target.

Distress Trajectories for Parents of Children With DSD: A Growth Mixture Model

OBJECTIVE

This study identifies trajectories of parent depressive symptoms after having a child born with genital atypia due to a disorder/difference of sex development (DSD) or congenital adrenal hyperplasia (CAH) and across the first year postgenitoplasty (for parents who opted for surgery) or postbaseline (for parents who elected against surgery for their child). Hypotheses for four trajectory classes were guided by parent distress patterns previously identified among other medical conditions.

METHODS

Participants included 70 mothers and 50 fathers of 71 children diagnosed with a DSD or CAH with reported moderate to high genital atypia. Parents were recruited from 11 US DSD specialty clinics within 2 years of the child's birth and prior to genitoplasty. A growth mixture model (GMM) was conducted to identify classes of parent depressive symptoms over time.

RESULTS

The best fitting model was a five-class linear GMM with freely estimated intercept variance. The classes identified were termed "Resilient," "Recovery," "Chronic," "Escalating," and "Elevated Partial Recovery." Four classes have previously been identified for other pediatric illnesses; however, a fifth class was also identified. The majority of parents were classified in the "Resilient" class (67.6%).

CONCLUSIONS

This study provides new knowledge about the trajectories of depressive symptoms for parents of children with DSD. Future studies are needed to identify developmental, medical, or familial predictors of these trajectories.

Stigma by Association: Parent Stigma and Youth Adjustment in Inflammatory Bowel Disease

OBJECTIVE

Examine the indirect association between parents' experience of stigma (i.e., associative stigma) and youth depressive symptoms through the serial effects of associative stigma on parent and youth illness intrusiveness in pediatric inflammatory bowel disease (IBD).

METHODS

During routine clinic visits, 150 youth with well-controlled IBD (ages 10-18 years) completed measures of perceived illness intrusiveness and depressive symptoms. Parents completed measures of associative stigma and illness intrusiveness. Pediatric gastroenterologists provided ratings of IBD disease severity.

RESULTS

Structural equation modeling revealed significant direct associations for associative stigma → parent illness intrusiveness, parent illness intrusiveness → youth illness intrusiveness, and youth illness intrusiveness → youth depressive symptoms. Results also revealed a significant associative stigma → parent illness intrusiveness → youth illness intrusiveness→ youth depressive symptoms serial mediation path, indicating that parents' experience of associative stigma indirectly influenced youth depressive symptoms through its sequential effects on parent and youth perceived illness intrusiveness.

CONCLUSIONS

Parents who face stigma related to their child's IBD (i.e., associative stigma) are more likely to experience IBD-induced lifestyle intrusions (i.e., illness intrusiveness), which in turn is associated with youths' illness intrusiveness and ultimately youth depressive symptoms. These findings provide further evidence for the important role of illness-related stigma in pediatric IBD, particularly the transactional relation between parents' associative stigma and youths' illness appraisals and emotional functioning. The clinical implications of our results for addressing adjustment difficulties in youth with IBD are also discussed.

Psychological adjustment outcomes among pediatric brain tumor survivors: A meta-analysis

BACKGROUND

Pediatric brain tumor survivors (PBTS) are at significant risk for psychological adjustment difficulties, including greater depressive and anxious symptomology. Systematic reviews have identified this heightened risk among youth with medical conditions, but these reviews have not been specific to PBTS. Therefore, the current study aimed to directly examine the psychological adjustment of PBTS as compared to healthy peers.

PROCEDURE

A systematic review and meta-analysis was conducted using PubMed, PsychInfo, and Academic Search Premier databases. The search yielded 2833 articles, with 22 articles meeting inclusion criteria.

RESULTS

A statistically significant overall medium effect size (Hedge's g = 0.32) indicated that PBTS exhibited poorer overall psychological adjustment relative to healthy comparison groups. Studies that included younger children were associated with larger between-group differences. When evaluating specific outcomes, PBTS had relatively higher levels of depressive symptoms (Hedge's g = 0.36), anxious symptoms (Hedge's g = 0.11), and general distress (Hedge's g = 0.22), but not more externalizing problems.

CONCLUSIONS

The present study confirmed that PBTS are indeed at greater risk for psychological adjustment difficulties relative to healthy comparison groups. These findings highlight the importance of psychosocial screening among this population. Given that depressive symptoms were the most elevated relative to healthy peers, investigation of such symptomatology among PBTS is particularly important.

The Relationship Between Parent Distress and Child Quality of Life in Pediatric Cancer: A Meta-Analysis

PROBLEM

Pediatric cancer places both parents and children at risk for psychosocial difficulties, including a specific risk for diminished quality of life. Previous research has identified relationships between parent and child psychosocial adjustment outcomes (e.g., depression, anxiety), yet the relationships between parent adjustment and child quality of life have yet to be comprehensively evaluated via meta-analysis.

ELIGIBILITY CRITERIA

A systematic review and meta-analysis were conducted using EBSCO, with PsychINFO, MEDLINE, Academic Search Premiere, and Health Source: Nursing/Academic Edition.

SAMPLE

Fourteen studies met inclusion criteria.

RESULTS

Fourteen correlations from 1646 parents of children with cancer were evaluated, resulting in a medium-magnitude correlation between parent psychosocial adjustment and child quality of life (r = 0.23, p < .001). Additional analyses evaluating the relationship between parent psychosocial adjustment and child social/emotional quality of life resulted in a medium-magnitude correlation (r = 0.24, p < .001).

CONCLUSIONS

A significant relationship exists between parent psychosocial adjustment and child quality of life. However, this relationship appears slightly less strong than those found in meta-analyses evaluating other child psychosocial adjustment outcomes.

IMPLICATIONS

Parent distress is an important factor to evaluate in the context of pediatric cancer, as it appears to have implications for child quality of life, in addition to other child psychosocial adjustment outcomes.

Predictors of Psychosocial Distress in Parents of Young Children with Disorders of Sex Development

PURPOSE

We evaluated demographic, financial and support predictors of distress for parents of young children with disorders of sex development including atypical genital development, and characterized early parental experiences. This work extends our previous findings to identify those parents at risk for distress.

MATERIALS AND METHODS

Participants included mothers (76) and fathers (63) of a child (78) diagnosed with disorders of sex development characterized by moderate to severe genital atypia. Parents completed a demographic questionnaire, measures of anxious and depressive symptoms, quality of life, illness uncertainty and posttraumatic stress symptoms, and rated their satisfaction with the appearance of their child's genitalia.

RESULTS

Depressive and posttraumatic stress symptoms of caregivers were comparable to standardized norms while levels of anxious symptoms were below norms. A subset of parents reported clinically elevated symptoms. Overall 26% of parents reported anxious symptoms, 24% reported depressive symptoms and 17% reported posttraumatic stress symptoms. Levels of illness uncertainty were lower than those of parents of children with other chronic illnesses. Differences by parent sex emerged, with mothers reporting greater distress. Lower income, increased medical care and travel expenses, and having no other children were related to increased psychosocial distress.

CONCLUSIONS

Early psychosocial screening is recommended for parents of children with disorders of sex development. Clinicians should be aware that financial burden and lack of previous parenting experience are risk factors for distress.

Uncertainty and Posttraumatic Stress: Differences Between Mothers and Fathers of Infants with Disorders of Sex Development

Parents of children with disorders of sex development (DSD) report significant psychological distress, including posttraumatic stress symptoms (PTSS), with mothers consistently reporting higher rates of psychological distress than fathers. However, psychological factors contributing to PTSS in both parents are not well understood. The present study sought to fill this gap in knowledge by examining PTSS and illness uncertainty, a known predictor of psychological distress, in parents of children recently diagnosed with DSD. Participants were 52 mothers (M_age = 32.55 years, SD = 5.08) and 41 fathers (M_age = 35.53 years, SD = 6.78) of 53 infants (M_age = 9.09 months, SD = 6.19) with DSD and associated atypical genital development. Participants were recruited as part of a larger, multisite study assessing parents' psychosocial response to their child's diagnosis of DSD. Parents completed measures of illness uncertainty and PTSS. Mothers reported significantly greater levels of PTSS, but not illness uncertainty, than fathers, and were more likely than fathers to report clinical levels of PTSS (21.2% compared to 7.3%). Hierarchical regression revealed that parent sex, undiagnosed or unclassified DSD status, and illness uncertainty were each associated with PTSS. The overall model accounted for 23.5% of the variance associated with PTSS. Interventions targeting illness uncertainty may be beneficial for parents of children with newly diagnosed DSD.

Featured Article: The Relationship Between Parent and Child Distress in Pediatric Cancer: A Meta-Analysis

Objective

Parents and children affected by pediatric cancer are at risk for psychological distress, including depression, anxiety, and post-traumatic stress. A link is believed to exist between parent and child distress; however, no systematic analysis of this relationship has occurred. A meta-analysis was conducted to assess the relationship between parent and child distress among families affected by pediatric cancer.

Methods

A systematic review and meta-analysis was conducted using EBSCO (searching PsycINFO, MEDLINE, Academic search Premiere, and Health Source: Nursing/Academic Edition) and PubMed. The initial search yielded a total of 29,118 articles. Inclusion criteria were that studies assessed the relation between parent and child distress in the context of pediatric cancer, were written in English, and were published in peer-reviewed journals. 28 articles met inclusion criteria.

Results

A statistically significant association was found between overall parent and child distress (r = .32, p < .001), such that increased parent-reported distress was associated with increased distress in their children. Significant relationships were also present among each type of parental distress (i.e., depression, anxiety, post-traumatic stress, and global distress; rs = .31–.51, ps < .001) and overall child distress. Moderation analyses via meta-regression indicated that parent proxy-report of child symptoms was associated with a stronger relationship between parent and child distress than child self-report of their own distress.

Conclusions

Aligned with the social–ecological framework, familial factors appear to be highly relevant in understanding distress following pediatric cancer diagnosis. Indeed, greater parent distress was associated with greater child distress.

Exploratory Factor Analysis of the Mishel Uncertainty in Illness Scale Among Adolescents and Young Adults With Chronic Medical Conditions

OBJECTIVE

To identify a developmentally relevant factor structure of the Mishel Uncertainty in Illness Scale-Community form (MUIS-C) among adolescents and young adults with chronic medical conditions.

METHODS

Data on college students with a self-reported chronic medical condition (N = 238) were collected between November 2013 and May 2015. Participants completed the MUIS-C as part of a larger questionnaire battery. An exploratory factor analysis and a confirmatory factor analysis were conducted.

RESULTS

The exploratory factor analysis resulted in a 22-item model with two factors termed: (a) Ambiguity/Future Uncertainty (α = .93), and (b) Unpredictability (α = .89). The confirmatory factor analysis and a correlated uniquenesses model, which evaluated method effects, supported the two-factor model.

DISCUSSION

These findings highlight the unique nature of illness uncertainty among adolescents and young adults and show the clinical and research utility of the MUIS-C for this population. Future investigations should examine how the two factors relate to distress among adolescents and young adults.

Preliminary exploration of secondhand smoke exposure in youth with Sickle Cell Disease: biochemical verification, pulmonary functioning, and health care utilization

Exposure to secondhand smoke (SHSe) can compound an already challenging set of health problems for youth with Sickle Cell Disease (SCD). Exposure to electronic cigarettes may also impact SCD symptomology and respiratory functioning. This study built on these previous findings by a) utilizing two objective measures of SHSe, salivary cotinine and exhaled carbon monoxide and b) examining the association of SHSe with emergency department utilization, physician-reported sickle cell crises, and pulmonary functioning. Caregivers (N = 31 dyads; Mage = 37.6 years; SD = 8.5 years) of youth with SCD (Mage = 9.0 years; SD = 4.5 years) completed self-report measures of tobacco/nicotine use. Youth provided a saliva sample to assess cotinine levels, and performed pulmonary function tests. Dyads provided breath samples for measurement of eCO. A chart review was conducted to obtain medical history and utilization. Majority of youth (88%) were exposed to SHS via salivary cotinine. Interestingly, no significant associations were observed between youth cotinine levels and emergency department utilization, physician-reported sickle cell crises, or pulmonary functioning. Present findings indicate a need to assess for SHSe using objective assessment measures. Future research should investigate which specific factors contribute to increase SHSe/SHVe in youth with SCD.

Baseline Characteristics of Infants With Atypical Genital Development: Phenotypes, Diagnoses, and Sex of Rearing

Purpose

Little is known about the phenotypes, diagnoses, and sex of rearing of infants with atypical genital development in the United States. As part of a multicenter study of these infants, we have provided a baseline report from US difference/disorder of sex development clinics describing the diagnoses, anatomic features, and sex of rearing. We also determined whether consensus guidelines are followed for sex designation in the United States.

Methods

Eligible participants had moderate-to-severe genital atypia, were aged <3 years, and had not undergone previous genitoplasty. Karyotype, genetic diagnosis, difference/disorder of sex development etiology, family history, and sex of rearing were collected. Standardized examinations were performed.

Results

Of 92 subjects, the karyotypes were 46,XX for 57%, 46,XY for 34%, and sex chromosome abnormality for 9%. The median age at the baseline evaluation was 8.8 months. Most 46,XX subjects (91%) had congenital adrenal hyperplasia (CAH) and most 46,XY subjects (65%) did not have a known diagnosis. Two individuals with CAH underwent a change in sex of rearing from male to female within 2 weeks of birth. The presence of a uterus and shorter phallic length were associated with female sex of rearing. The most common karyotype and diagnosis was 46,XX with CAH, followed by 46,XY with an unknown diagnosis. Phenotypically, atypical genitalia have been most commonly characterized by abnormal labioscrotal tissue, phallic length, and urethral meatus location.

Conclusions

An increased phallic length was positively associated with rearing male. Among the US centers studied, sex designation followed the Consensus Statement recommendations. Further study is needed to determine whether this results in patient satisfaction.

Post traumatic stress symptoms in parents of children with cancer: A mediation model

OBJECTIVE

Caregivers of pediatric cancer patients are at risk for posttraumatic stress symptoms (PTSS). Previous literature has identified caregiver illness uncertainty as a predictor of PTSS, yet little is known about the mechanism by which illness uncertainty may affect PTSS. Rumination, or perseverations about the cause and consequences of an event, has been related to posttraumtic stress disorder in other populations. However, limited research of this relationship exists for pediatric cancer caregivers. Further, no studies have evaluated rumination in relation to illness uncertainty. The current study examined rumination in relation to illness uncertainty and PTSS in caregivers with children actively receiving treatment for cancer. It was hypothesized that rumination would be related to illness uncertainty and would mediate the relationship between illness uncertainty and PTSS.

METHODS

Caregivers (N = 59) completed the Parent Perception of Uncertainty Scale, Ruminative Responses Scale, and the Impact of Event Scale-Revised.

RESULTS

illness uncertainty was identified as a significant predictor of rumination (B = 0.148, p = .015), and rumination was a significant predictor of PTSS (B = 1.83, p < .001). Biased-corrected bootstrap regression analysis revealed that rumination mediated the relationship between illness uncertainty and PTSS (R² = 0.53, p < .001).

CONCLUSIONS

Rumination was identified as a mediator between the relationship of illness uncertainty and PTSS. These findings underscore the importance of rumination in caregivers of children with cancer, as a potential construct for identifying caregivers at risk of PTSS, and as a possible mechanism for targeted intervention.
