Intensity of CNS treatment for pediatric cancer: prediction of social outcomes in survivors.

PURPOSE: To evaluate the association of central nervous system (CNS) treatment intensity and the social functioning of children who have completed treatment for leukemia, lymphoma, and solid tumors outside the CNS. Furthermore, we expected that these associations would be moderated by child age at diagnosis and gender. METHOD: Peer, teacher, and self-report data were obtained for 82 cancer survivors (age 9-17 years) using classroom rating and nomination procedures that are widely used in research on social development. Information regarding cranial radiation therapy (CRT), intrathecal chemotherapy (ITC), and systemic methotrexate were obtained from medical records and used to create a composite index of CNS treatment intensity. RESULTS: Higher scores on the index of CNS treatment intensity were associated with poorer peer acceptance, fewer friendships, greater social sensitivity-isolation, and diminished leadership-popularity based on peer-report. These associations were stronger for boys and children who were younger (<10 years old) at diagnosis. In contrast, CNS treatment intensity was only predictive of teacher-perceptions of aggressive-disruptive behavior and it was unrelated to social self-perceptions. CONCLUSION: These results suggest that children who receive CRT and ITC are at risk for problematic peer relations, particularly if they are male or younger at diagnosis. Given the stability of poor peer relationships and documented linkages between peer problems and subsequent academic and psychiatric difficulties, clinical services should address these issues. Research is needed to identify mechanisms that account for these outcomes and provide direction for prevention and treatment efforts.

Controlled study of critical parent and family factors in the obesigenic environment.

OBJECTIVE: Critical gaps remain in our understanding of the obesigenic family environment. This study examines parent and family characteristics among obese youth presenting for treatment in a clinic setting. RESEARCH METHODS AND PROCEDURES: Families of 78 obese youth (BMI z-score = 2.4; age, 8 to 16 years; 59% girls; 49% African-American) were compared with 71 non-overweight (BMI z-score = -0.02) demographically matched comparisons. Parents completed measures assessing family demographics, psychological distress (Symptom Checklist 90-Revised), and family functioning both broadly (Family Environment Scale: Conflicted, Support, Control) and at mealtimes (About Your Child's Eating-Revised: Mealtime Challenges, Positive Mealtime Interaction). Height and weight were obtained from all participants. RESULTS: Compared with mothers and fathers of non-overweight youth, parents of obese youth had significantly higher BMIs (p < 0.001). Mothers of obese youth reported significantly greater psychological distress (p < 0.01), higher family conflict (p < 0.05), and more mealtime challenges (p < 0.01). Less positive family mealtime interactions were reported by both mothers (p < 0.01) and fathers (p < 0.05) of obese youth. These group differences did not vary by child sex or race. Logistic regression analyses indicated that maternal distress and mealtime challenges discriminated between obese and non-overweight youth after controlling for maternal BMI. Family conflict was explained, in part, by maternal distress. DISCUSSION: Obese youth who present for treatment in a clinic setting are characterized by psychosocial factors at the parent and family level that differ from non-overweight youth. These data are critical because they identify factors that may be serving as barriers to a family's or youth's ability to implement healthy lifestyle behaviors but that are potentially modifiable.

Parent and family factors associated with child adjustment to pediatric cancer.

OBJECTIVE: To identify factors that influence the association between parent and child distress among families of children with cancer and comparison peers. METHODS: Parent and child distress, social support, and family environment were assessed among families of 95 children with cancer (94 mothers, 67 fathers) and 98 comparison peers (97 mothers, 77 fathers). RESULTS: Significant associations were found between parent and child distress. For models examining the impact of fathers' distress on children, several moderators were identified (i.e., family environment, child age and gender, a cancer diagnosis, and treatment severity). Family environment also partially mediated father and child distress. CONCLUSIONS: Children whose parents were distressed were more likely to be distressed themselves. Subgroups of children were particularly vulnerable, indicating a need to identify further mechanisms of risk and resilience and to develop family-based interventions. Support was found for including fathers as independent sources of information in pediatric psychology research and clinical practice.

Parent perceptions of nutritional issues during their child's treatment for cancer.

To examine family mealtime interactions, parental concerns about nutrition, and body mass index (BMI) among children with cancer who did not have primary central nervous system involvement. Parents of 95 children receiving treatment for cancer and 95 comparisons completed the About Your Child's Eating-Revised (AYCE-R) measure. Anthropometric data for children with cancer were obtained from medical charts at diagnosis and again when the AYCE-R was administered. No differences in mealtime interactions were found between children with cancer and comparisons, but parents of children with cancer reported greater concern about their child's weight. Anthropometric measures for children with cancer were consistent with national norms. However, children with cancer were somewhat underweight at diagnosis and became heavier over time. Lower BMI was associated with mother and father report of greater resistance from the child at mealtime, father report of his own aversion to family meals, and more severe treatment. The impact of cancer on family mealtime interactions and BMI appeared minimal during treatment. However, further longitudinal research is needed given the risk for late effects, such as growth problems and obesity, among cancer survivors. Families also may benefit from ongoing education to optimize healthy lifestyles among survivors.

Emotional, social, and behavioral functioning of children with sickle cell disease and comparison peers.

This research examined the emotional, social, and behavioral functioning of children with sickle cell disease (SCD) and classroom comparison peers from the perspective of primary and secondary caregivers. It was hypothesized that children with SCD would have more internalizing (emotional) and social problems and fewer externalizing (behavioral) problems than comparison peers. Caregivers of 70 children with SCD and 67 comparison peers completed the Child Behavior Checklist (CBCL) during visits to the children's homes. Relative to comparison peers, children with SCD were perceived by primary caregivers as having more total and internalizing problems and less total competence. Additionally, significantly more children with SCD exceeded clinical cutoffs on the CBCL. While caregivers of children with SCD perceive these children to be at a slightly elevated risk for problems across multiple domains, a significant number of children with SCD have problems in the clinical range. The authors recommend that vigorous screening programs for mental health problems should be included in the routine care of children with SCD, and programs of psychosocial intervention research should be implemented to ameliorate problems for the children at greatest risk.

Behavioral reputation: a cross-age perspective.

This study examined the measurement of peer perceptions of behavioral reputation within the contexts of elementary, middle, and high school environments (Grades 2-12, N = 2,812) through the systematic evaluation of the psychometric properties of the Revised Class Play (A. S. Masten, P. Morison, & D. S. Pellegrini, 1985). Confirmatory factor analyses demonstrated that the data did not fit A. S. Masten et al.'s original 3-factor structure. Cross-loading of items and different patterns of association between subscales across age groups (elementary, middle, and high school) contributed to the overall poor fit. Exploratory factor analyses revealed an alternative 4-factor structure as a more reliable and valid means of assessing behavioral reputation regardless of the age of the peer group sampled. Both convergent and divergent patterns of associations emerged across developmental levels.

Brief report: child-rearing practices of caregivers with and without a child with juvenile rheumatoid arthritis: perspectives of caregivers and professionals.

OBJECTIVE: To evaluate predictions from professionals in pediatric rheumatology regarding the child-rearing practices of caregivers of children with juvenile rheumatoid arthritis (JRA) and healthy classmates. METHODS: Sixteen professionals identified items from the Child-Rearing Practices Report (CRPR) that were expected to differentiate between caregivers of children with JRA (64 mothers, 45 fathers) and caregivers of healthy classmates (64 mothers, 40 fathers). Families were interviewed, and physician ratings of disease severity were obtained. RESULTS: Experts predicted difficulties in protectiveness, discipline, and worry. Ratings from parents of children with JRA showed modest agreement with the professionals, surprising similarity to controls, and a limited association with disease factors. CONCLUSIONS: Contrary to expert opinion, JRA has only a modest influence on some child-rearing practices. Educating health care providers may minimize misperceptions about caring for children with JRA, and screening parents of children with more severe disease may assist in allocating education and services for families.

Social, emotional, and behavioral functioning of children with hemophilia.

This study examines the social, emotional, and behavioral functioning of children with hemophilia. Data were collected in the homes and schools of 40 boys with hemophilia and 40 comparison boys of the same race and age. Data on social, emotional, and behavioral functioning were collected from teachers, classmates, parents, and the participants. Children with hemophilia scored comparably with comparison peers in all areas of social functioning but reported more difficulties with emotional well-being, including more depressive symptomatology and lower self-perceptions. Parent report also indicated more difficulties with emotional well-being. Parents did not report significant differences in externalizing behavior problems. In conclusion, children with hemophilia were not found to be at increased risk of social or behavioral difficulties. However, both children with hemophilia and their parents identified more difficulties with emotional well-being. Nevertheless, approximately all mean scores for both groups remained within the normal range.

A controlled longitudinal study of the social functioning of children who completed treatment of cancer.

BACKGROUND: A follow-up assessment of social functioning was performed for children with cancer after completion of treatment. It was hypothesized that children who completed cancer treatment (CCT) would have more social problems than their peers who were not chronically ill (COMP) and that greater treatment intensity would be predictive of increasing social difficulties over time. PATIENTS AND METHODS: Peer, teacher, and self-reports of social functioning were obtained from 69 CCTs and 77 COMPs. Social reputation and social acceptance were evaluated cross-sectionally and longitudinally. RESULTS: Relative to COMPs, CCTs described themselves as more prosocial, were perceived by teachers as less aggressive, and were seen by peers as more sick, more tired, and as missing more school. Longitudinal analyses indicated that self-reported prosocial scores were significantly more stable over time for CCTs relative to COMPs. Children who received more intense treatment were perceived by peers as more prosocial and less aggressive, but as having fewer best friends 2 years after treatment ended. CONCLUSIONS: CCTs had minimal impact on their social functioning as a result of their experience with cancer for those children who have returned to school. These results suggest that routine interventions with regard to social functioning after treatment ends may not be warranted for most CCTs when an integrated program of psychosocial services coordinated by mental health professionals has been provided during treatment. However, children who have undergone especially intense treatment may be at some risk for social problems.

Methylphenidate and attributions in boys with attention-deficit hyperactivity disorder.

In Experiment 1, 28 attention-deficit hyperactivity disorder (ADHD) boys underwent a double-blind, placebo-controlled medication assessment in a summer day-treatment program. Daily, boys were asked questions to assess their attributions for and evaluations of their behavior. Objective measures showed improved behavior with methylphenidate; however, boys tended to attribute their performance to effort rather than to medication, particularly when medicated. Experiment 2 involved 38 ADHD boys the following summer and replicated the procedures in Experiment 1, with the addition of a no-pill condition and a comparison of attributions for success and failure outcomes. Simply taking a pill (no-pill vs. placebo comparison) did not show significant effects, whereas the results of Experiment 1 were replicated with placebo-methylphenidate comparisons. Across drug conditions a self-enhancing attributional pattern was obtained; the majority of attributions for success were to ability or effort, whereas attributions for failure were to the pill or to counselors.

A controlled longitudinal study of the social functioning of children with juvenile rheumatoid arthritis.

OBJECTIVE: To complete an assessment of social functioning of children with juvenile rheumatoid arthritis (JRA) and nonchronically ill controls who had been evaluated 2 years earlier (Noll et al., 2000) and to examine the impact of disease severity or disease activity over time on the social functioning of children with JRA. METHODS: Peer-, teacher-, and self-reports of social functioning were obtained from 57 children with JRA and 63 controls. Social reputation and social acceptance were examined cross-sectionally and longitudinally. RESULTS: Cross-sectional analyses indicated no significant differences between children with JRA and controls on measures of social functioning. For children with more severe disease, like ratings declined over the 2-year period relative to children with mild disease. Children with active disease were chosen fewer times over the 2-year period as a best friend than children in remission. CONCLUSIONS: Because children with severe or active JRA may be at risk for difficulties with social acceptance over time, they are appropriate targets for interventions that ameliorate or prevent these difficulties.

Comparing parental distress, family functioning, and the role of social support for caregivers with and without a child with juvenile rheumatoid arthritis.

OBJECTIVE: To assess parental distress, family functioning, and social support among parents of children with a lifetime diagnosis of juvenile rheumatoid arthritis (JRA) and comparison families. METHODS: Parents of 64 children with JRA (64 mothers, 46 fathers) completed questionnaires and in-home interviews along with 64 matched comparison families. Average time since diagnosis for children with JRA was 70 months. RESULTS: Families of children with JRA generally reported levels of parental distress, family functioning, and social support similar to those for comparison families. More mothers of children with JRA exceeded the clinical cutoff on the SCL-90-R than comparison mothers. Although disease characteristics and social support did not distinguish subgroups of parents at greater risk for problems, family supportiveness and conflict were associated with caseness for mothers of children with JRA. CONCLUSIONS: Families of children with JRA exhibited substantial resilience over the long term. Further multisite study of children recently diagnosed and with more severe forms of JRA is warranted to determine intervention needs, especially for mothers.
