Behavioral and cognitive interventions in the treatment of pain in children.

A wide range of behavioral and cognitive techniques have been found to be efficacious for helping children to cope with acute pain. Research into the clinical applicability of these interventions is at an early stage but increasingly is being recognized as an important future direction. Many existing interventions and assessment tools are reasonably easy to use, allowing practitioners to have the tools to identify children most vulnerable to pain and to significantly reduce pain-related distress in these children.

Pain-sensitive temperament: does it predict procedural distress and response to psychological treatment among children with cancer?

OBJECTIVE: To evaluate the relationship between pain sensitivity and children's distress during lumbar punctures (LPs), and whether pain sensitivity functions as a moderator of children's responses to a psychological intervention aimed at reducing LP distress. METHOD: Fifty-five children with acute lymphoblastic leukemia (ages 3 to 18) and their parents completed a questionnaire measure of pain sensitivity. Self-report, physiological, and observed measures of distress were collected during the study baseline LP. Children were then randomized into a psychological intervention or an attention control group. Postintervention and follow-up LPs were observed. RESULTS: Higher levels of pain sensitivity were associated with greater anxiety and pain, both prior to and during the LP. Preliminary analyses indicated that pain sensitivity moderated the effects of intervention on distress. Children who were more pain-sensitive and who received no intervention showed greater increases in LP distress over time. In contrast, children who were more pain-sensitive and who received intervention showed greater decreases in LP distress over time. CONCLUSIONS: A measurement of pain sensitivity may be useful in pediatric oncology settings for effectively targeting pain-vulnerable children for psychological intervention. Preliminary analyses indicate that an empirically-supported intervention for procedural distress is efficacious for those children who are most pain-sensitive.

Alteration of memory in the reduction of children's distress during repeated aversive medical procedures.

The present study sought to reduce children's distress during aversive medical procedures using a brief, cost-effective intervention aimed at reframing memory. Fifty children diagnosed with leukemia (25 treatment, 25 attention control, aged 3-18) were observed as they underwent 3 consecutive lumbar punctures (LPs; baseline, postintervention, and follow-up). Self-report, physiological, and observable distress measures were collected before and after each LP. At posttreatment, children in the intervention group showed reductions in anticipatory physiological and self-report ratings relative to the control group. At follow-up, these effects generalized to reductions in procedural distress. These results suggest that (a) a simple memory-based intervention is efficacious at reducing children's distress and (b) benefits from this intervention are maintained over 1 week even without continued intervention.

Smoking in adult survivors of childhood acute lymphoblastic leukemia.

BACKGROUND: Health-related behaviors are of particular concern in survivors of childhood cancer as they are at increased risk for second cancers and long-term organ dysfunction. The purpose of this study was to compare the smoking behavior and associated factors in young-adult survivors of childhood acute lymphoblastic leukemia (ALL) with those in sibling controls. METHODS: A telephone interview that surveyed smoking behavior was conducted with 592 young-adult survivors, treated before age 20 years on Children's Cancer Group ALL protocols, and 409 sibling controls. Using stratified chi-squared analyses and Cox proportional hazards models, we compared the rates of smoking initiation and smoking cessation between survivors and control subjects. Demographic characteristics (age, sex, race, and education) and psychological factors (mood and self-concept) were examined as predictors interacting with survivorship in logistic regression analyses to try to distinguish a subgroup of survivors who may be at greater risk for smoking. RESULTS: Survivors were significantly less likely to have ever smoked (23.0% versus 35.7%; P<.0001) and thus were less likely to ever be regular, daily smokers than sibling controls (19.1% versus 31.3%; P<.0001). Survivors were less likely to quit smoking than sibling controls (26.6% versus 35.2%), although this result was not statistically significant. There were no interactions between survivor status and either demographic or psychological features on smoking behavior. CONCLUSIONS: Young-adult survivors of childhood ALL are less likely to experiment with smoking but, once having started, are at similar risk for becoming habitual, persistent smokers as sibling controls.

Comparison of psychologic outcome in adult survivors of childhood acute lymphoblastic leukemia versus sibling controls: a cooperative Children's Cancer Group and National Institutes of Health study.

PURPOSE: To determine psychologic outcome, with the focus on emotional or mood state, of young adult survivors of childhood acute lymphoblastic leukemia (ALL) compared with sibling controls and to identify vulnerable subgroups at highest risk for negative mood. PATIENTS AND METHODS: Adult survivors (n = 580), aged > or = 18 years, who were treated before age 20 years on Children's Cancer Group (CCG) protocols for ALL and 396 sibling controls were administered a structured telephone interview and the Profile of Moods State (POMS), a standardized measure of affective state. RESULTS: Survivors had higher total mood scores (which indicates greater negative mood) than sibling controls (P<.01) and reported more tension (P< .01), depression (P<.01), anger (P<.01), and confusion (P<.01), but not more fatigue or less vigor. Female, minority, and unemployed survivors reported the highest total mood disturbance. Overall, survivors were more likely to be unemployed (P<.05) or working less than half-time (P<.01) compared with controls. CONCLUSION: This large, sibling-controlled, multisite study of young adult survivors of childhood ALL treated on CCG protocols after 1970 found significant increased negative mood in survivors, not accounted for by reported energy level differences, which suggests that these emotional effects are not likely the result of current illness. Survivors are less likely to be fully employed. Female, minority, and unemployed survivors are at greatest risk for emotional sequelae, a finding that indicates the need for targeted, preventive intervention.

Sibling Adaptation to Childhood Cancer Collaborative Study: the association of sibling adaptation with maternal well-being, physical health, and resource use.

This multi-institutional study investigated the association of behavioral/emotional adaptation among siblings of children with cancer with maternal general well-being, physical health, and resource use. One hundred seventy siblings and mothers completed standardized interviews and self-report measures 6 to 42 months after the cancer was diagnosed. As a group, mothers of children with cancer reported significantly lower levels of well-being than matched controls. When stratified according to the level of the sibling's behavioral/emotional adaptation, mothers of siblings in the Dysfunctional group (1) reported the lowest levels of well-being; (2) during the preceding year, were more likely to have sought professional services than mothers of children in the Resilient group; and (3) were least likely to have found social support helpful. Our results support an association between maternal well-being and sibling adjustment but show it is unlikely that nonspecific social support will improve adjustment. The rationale for problem-solving training for mothers is provided.

Birth defects in offspring of adult survivors of childhood acute lymphoblastic leukemia. A Childrens Cancer Group/National Institutes of Health Report.

BACKGROUND: It is not known if therapy for acute lymphoblastic leukemia (ALL) during childhood increases the risk of birth defects in the offspring of adult survivors. The Childrens Cancer Group (CCG), in collaboration with the National Institutes of Health (NIH), conducted a retrospective cohort study of adults successfully treated for childhood ALL to determine if their offspring had an increased incidence of birth defects compared with the offspring of their sibling controls. METHODS: Study subjects were patients who had been enrolled on CCG ALL protocols, who were treated for ALL prior to age 20, who survived at least 2 years, and who were at least age 18. Survivors (N=593) and sibling controls (N=409) were interviewed by telephone. RESULTS: The mean age of survivors was 22.6 years; the mean age of controls was 25.2 years. Among survivors, 93 (15.7%) had given birth to or fathered a total of 140 live-born offspring, (mean age, 3.4 years), and 122 (29.8%) sibling controls had given birth to or fathered a total of 228 live-born offspring (mean age, 5.9 years). There was no difference in the rate of birth defects between offspring of survivors and offspring of controls (3.6% [5 of 140] vs. 3.5% [8 of 228]; relative risk, 1.02; 95% confidence interval, 0.34, 3.05). No specific ALL therapy was associated with an increased rate of birth defects. Only female survivors reported offspring with birth defects (P=0.0735). CONCLUSIONS: Adult survivors of childhood ALL in our study were not at greater risk for having offspring with birth defects compared with sibling controls. Although this is the largest group of ALL survivors studied to date, the number of offspring is still not large enough to detect small but significant differences in rare events such as birth defects. Studies following this cohort into later adulthood and studies of additional ALL survivors are necessary to adequately quantify the risks.

Sibling adaptation to childhood cancer collaborative study: health outcomes of siblings of children with cancer.

OBJECTIVE: This seven-site study examined the overall health status, healthcare utilization, somatization, and health-risk behaviors of siblings of children with cancer compared to these factors in matched controls or normative data. The study also examined whether informants (i.e., siblings, parents, physicians) differed in their assessments of the above health domains. DESIGN: Subjects were 254 siblings of children with cancer from seven different pediatric oncology treatment centers that participated in the Sibling Adaptation to Childhood Cancer Collaborative study group. Predictors of the siblings' health status, healthcare utilization, somatization, and health-risk behaviors were identified, and the relationship between these health domains and the siblings' resiliency vs. dysfunctionality were explored via interviews. RESULTS: Overall, siblings were found to be moderately healthy, although siblings report significant problems with sleeping and eating. Healthcare utilization appears to be reduced for siblings. Most importantly, the parents of these siblings are less likely to seek medical help for a variety of conditions for which parents of control children would bring their children to a doctor. A pattern emerged of parental underreporting of sibling health variables when compared to what the siblings themselves reported. When the relationship between health outcomes and the siblings' adaptation to their sick sibling's illness was examined, the resilient and dysfunctional groups significantly differed from each other. It appears that health outcomes are related to sibling adaptation to the changes brought about by their sick sibling's cancer diagnosis and treatment. CONCLUSIONS: The focus of care for families of children with cancer is often limited to the child with cancer. As indicated in this study, the "healthy" siblings may be overlooked in the process. While parents appear to recognize that their "healthy" children are complaining more about aches and pains, they may have little energy or time to attend to the needs of these other family members. It is the intent of this study to document what clinicians may expect and to highlight the need for evaluation of this otherwise neglected group.

Sibling adaptation to childhood cancer collaborative study: siblings' perceptions of the cancer experience.

Investigated responses of siblings (N = 254) of children with cancer to structured interviews designed to elicit thoughts and feelings about effects of cancer on self and family. Siblings indicated distress about family separations and disruptions, lack of attention, focus of family on the ill child, negative feelings in themselves and family members, cancer treatments and their effects, and fear of death. Siblings also reported becoming more compassionate, families becoming closer, and having experiences they otherwise would not have had. Age and gender differences in responses indicated distinctive perceptions of and vulnerability to the cancer experience. Older siblings were far more likely to report positive effects than younger siblings suggesting that level of maturity can moderate the stress of an ill child within the family.

Educational attainment in long-term survivors of childhood acute lymphoblastic leukemia.

OBJECTIVE: To determine the impact of treatment on scholastic performance in the first cohort of survivors of childhood acute lymphoblastic leukemia who are old enough to have completed their educational experience. DESIGN: Retrospective cohort study. SETTING: Twenty-three institutions in the Childrens Cancer Group. SUBJECTS: A total of 593 adult survivors of childhood acute lymphoblastic leukemia and 409 sibling controls. OUTCOME MEASURES: Enrollment in special programs, grades during high school, graduation from high school, college admission, and college graduation. RESULTS: After diagnosis, survivors were more likely than their sibling controls to enter a special education (relative risk [RR] = 3.4; P < .01) or a learning disabled (RR = 3.6; P < .01) program, while just as likely to enter gifted and talented programs (RR = 1.0). The risk associated with special education and learning disabled programs increased with increasing dose of cranial radiotherapy. Despite these problems, survivors generally had the same probability as their siblings of finishing high school, entering college, and earning a bachelor's degree. However, survivors treated with 24 Gy and those diagnosed before 6 years of age were less likely to enter college (RR = 0.67 and 0.6, respectively; P < .01). CONCLUSIONS: This large study demonstrates that childhood acute lymphoblastic leukemia survivors have a greater likelihood of being placed in special education or learning disabled programs than their siblings, but that most are able to overcome these problems. Dose of cranial radiotherapy and age at diagnosis are the most important education-related risk factors.

Visceral pain in infants.

Visceral pain in infants represents a complexity of interacting neural, developmental, psychosocial, and environmental factors, which must be separately and conjointly evaluated. Inhibitory mechanisms are not fully developed in infants and thus nociception is not readily dampened. Heightened behavioral responses to pain (e.g., crying) are likewise not easily inhibited. Esophageal pain and behaviors perceived by the caregiver to represent pain (e.g., crying and retching) can potentially affect normal growth and development. The response of the infant to pain and other visceral sensory stimuli and the ability to cope with these sensations (painful and nonpainful) are shaped by the relationship of the infant with the primary caregiver, usually the mother. Neural mechanisms of pain transmission and inhibition are reviewed, as well as biopsychosocial and environmental characteristics that can shape or contribute to infant pain syndromes. Proposed multifaceted clinical treatment strategies are aimed at decreasing efforts to dampen excitatory neural sensory signaling and improving the mother/infant relationship and maternal behavioral response to the crying infant.

Sibling adaptation to childhood cancer collaborative study: prevalence of sibling distress and definition of adaptation levels.

A multisite collaborative study assessed the frequency and intensity of emotional/behavioral distress in siblings of children with cancer. A sample of 254 siblings, aged 4 to 18 years, and their parents completed interviews and self-report measures 6 to 42 (average 22.5) months after diagnosis of cancer in a brother or sister. Matched controls were obtained from respondents to the Child Health Supplement of the National Health Interview Survey administered in 1988 (CHS88). Before diagnosis, the prevalence of parent-reported emotional/behavioral problems among siblings was similar to that in the general population (7.7% vs 6.3%; p = not significant). After diagnosis, prevalence rose to 18% among siblings. When siblings were grouped according to the presence or absence of problems exacerbated by and/or arising after diagnosis, four levels of adaptation, consistent with scores on the Behavior Problem Scales from the CHS88, emerged. This differentiation may help explain inconsistencies in sibling response reported previously and provides a framework for investigating factors that enhance adaptation.
