Temperament, Anxiety, and the Processing of Threat-Relevant Stimuli.

This article discusses converging evidence from developmental, clinical, and cognitive psychology suggesting that there is significant overlap between research findings on affect, temperament, and attentional processes associated with pathological anxiety. We offer a proposal for the integration of these 3 areas aimed at developing a more clear understanding of the developmental sequence and operative mechanisms in the dysregulation of negative affect and the development of symptoms of anxiety pathology. We review evidence for a model indicating that reactive and effortful temperamental processes, possibly mediated by an attentional bias toward threat-relevant information, interact to produce problems of dysregulated negative affect and elevated levels of pathological anxiety. This model may assist in understanding the development of anxiety disorders, identifying children at risk for such disorders, and selecting points of entry for both preventative and curative interventions.

Parenting Stress Among Caregivers of Children With Chronic Illness: A Systematic Review

OBJECTIVE To critically review, analyze, and synthesize the literature on parenting stress among caregivers of children with asthma, cancer, cystic fibrosis, diabetes, epilepsy, juvenile rheumatoid arthritis, and/or sickle cell disease. Method PsychInfo, MEDLINE, and Cumulative Index to Nursing and Allied Health Literature were searched according to inclusion criteria. Meta-analysis of 13 studies and qualitative analysis of 96 studies was conducted. Results Caregivers of children with chronic illness reported significantly greater general parenting stress than caregivers of healthy children (d = .40; p = ≤.0001). Qualitative analysis revealed that greater general parenting stress was associated with greater parental responsibility for treatment management and was unrelated to illness duration and severity across illness populations. Greater parenting stress was associated with poorer psychological adjustment in caregivers and children with chronic illness. Conclusion Parenting stress is an important target for future intervention. General and illness-specific measures of parenting stress should be used in future studies.

Attentional retraining: A randomized clinical trial for pathological worry ☆

OBJECTIVE Research has consistently shown that highly anxious individuals tend to show an attentional bias in favor of threat cues (i.e., a threat bias). Further, recent evidence suggests that it is possible to modify patterns of attention allocation for such stimuli and the resulting changes in attention allocation alter affective responses to stress. However, to date such changes in patterns of attention have been shown only over brief time intervals and only in non-anxious individuals who lack a pre-existing attentional bias. In contrast, the present study tested the efficacy of such attentional training in a sample of severe worriers over an extended period of time using psychometrically validated measures of anxiety and depression. METHOD Twenty-four adult participants reporting severe worry were randomly assigned to receive five sessions of either computer-delivered attentional retraining or sham training. The study was conducted from January to August 2001 and June to August 2002. RESULTS Significant Treatment Group X Time interactions were found for both threat bias (p=001) and a composite measure of anxious and depressive symptoms (p=.002). Compared to sham-training, the active retraining program produced significant reductions in both threat bias and symptoms. CONCLUSIONS These data support the view that an attentional bias in favor of threat cues is an important causal factor in generalized anxiety and suggest that a computer-based attentional retraining procedure may be an effective component of treatment.

Communicating and Understanding the Purpose of Pediatric Phase I Cancer Trials

PURPOSE Quality informed consent should provide a clear understanding of the purpose of the research. Given the ethical challenges of pediatric phase I cancer trials, it is important to investigate physician-parent communication during informed consent conferences (ICCs) and parental understanding of the purpose of these studies. METHODS In the multisite Informed Consent in Pediatric Phase I Cancer Trials study, 85 ICCs for phase I research between June 2008 and May 2011 were directly observed, and 60 parents were subsequently interviewed. The scientific purpose was defined as composite understanding of drug safety, dose finding, and dose escalation. We determined the frequency with which physicians explained these and other phase I-related concepts during the ICC. Parent interviews were analyzed to determine understanding. RESULTS The child was present at 83 of 85 ICCs. Only 32% of parents demonstrated substantial understanding of the scientific purpose of phase I cancer trials; 35% demonstrated little or no understanding. Parents of higher socioeconomic status and racial majority status were more likely to understand the scientific purpose. Factors associated with understanding included physician explanation of the goal of the applicable phase I protocol offered (explained in 85% of ICCs) and explanation of the dose cohorts (explained in 43% of ICCs). Physicians explained drug safety in 23% of ICCs, dose finding in 52% of ICCs, and dose escalation in 53% of ICCs. CONCLUSION Many parents of children participating in phase I trials do not understand the purpose of these trials. Physician-parent communication about the purpose of phase I research is lacking during ICCs.

The concept of bootstrapping of structural equation models with smaller samples: an illustration using mealtime rituals in diabetes management.

Objective: The objective of this study was to offer a practical demonstration of the use of bootstrapping in structural equation modeling (SEM) with smaller samples by evaluating family dinnertime rituals at the intersection between the family social environment and pediatric type 1 diabetes mellitus management. Method: Participants were 77 children and adolescents aged 6 to 18 years and their mothers from a larger study of child and parental challenges related to managing the treatment regimen and correlates of adherence. SEM was used to test a model of maternal reports of the family social environment as exogenous variables with mealtime rituals and child hemoglobin A1c levels as endogenous variables. The bootstrapping procedure and the Bollen-Stine bootstrapped &khgr;2 test were then applied to test the stability and appropriateness of this model. Results: Using SEM, the final model had robust goodness-of-fit indicators and revealed that the family social environment characteristics of control and cohesion were related to mealtime rituals, which was associated with hemoglobin A1c levels. The bootstrapping procedure indicated that the parameter estimates were very stable, thus lending greater credence to the model. The Bollen-Stine approach provided evidence that the entire hypothesized model was not significantly different from the model derived from bootstrapping. Conclusions: This investigation offers a practical demonstration of the bootstrapping technique and the Bollen-Stine approach for testing models on smaller samples in SEM. These techniques may be used with relatively small samples, which are common in developmental/behavioral pediatrics and pediatric psychology research.

A feasibility trial of a video intervention to improve informed consent for parents of children with leukemia.

Research on parental understanding of informed consent for pediatric randomized clinical trials (RCTs) has highlighted weaknesses in understanding of key aspects of informed consent. The goals of the current study were to assess the feasibility of and parental satisfaction with a video intervention to improve informed consent for pediatric leukemia RCTs and to compare parental question asking during informed consent conferences (ICCs) for parents in the current study with historical control data.

Anticipatory guidance to improve informed consent: a new application of the concept.

Although the concept of anticipatory guidance has long been used in general pediatrics to help prepare parents for what to expect in the coming months or year, this educational concept has not been transplanted for use in other contexts. The intervention described in this article uses the principles of anticipatory guidance in an effort to prepare parents of children with newly diagnosed acute leukemia for their upcoming discussions with their childs physician. Parents of children recently diagnosed with leukemia frequently feel overwhelmed and are anxious to discover what can be done to cure their child. By using the abilities of already medically trained oncology nurses and orienting them to conduct an intervention to educate, empathize, and prepare parents for the informed consent conference, this anticipatory guidance-based intervention was designed to target barriers to effective communication and increase the interactivity between families and health care providers.

Parent Participation and Physician-Parent Communication During Informed Consent in Child Leukemia

OBJECTIVE: In this study we evaluated the effectiveness of a physician-directed intervention at enhancing positive physician behaviors and communication strategies during informed consent conferences (ICCs) for pediatric acute leukemia clinical trials. PATIENTS AND METHODS: Physicians at 2 large pediatric hospitals were recruited to participate in a physician-directed intervention (PDI), which included 1 full-day seminar and successive half-day booster sessions. ICCs were then observed, audiotaped, coded, and analyzed to evaluate the effectiveness of the intervention. Data also were collected at 2 control sites. Between 2003 and 2007, 59 ICCs were observed and analyzed. RESULTS: Significant group differences were found in physician rapport-building behaviors. Physicians in the PDI + booster session group engaged in greater rapport-building than did physicians in the PDI group who did not attend booster sessions and physicians in the control group. No group differences were detected for physician partnership-building. In addition, parents in the PDI + booster session group engaged in more general communication and study-related communication, and mothers in the PDI groups asked significantly more questions per minute than did mothers in the control group. CONCLUSIONS: These results provide support for the effectiveness of the PDI at enhancing positive physician behaviors. Booster-session attendance is a critical component of physician-directed interventions to improve parental participation and physician-parent communication during ICCs.

Communication about the Risks and Benefits of Phase I Pediatric Oncology Trials

Introduction Phase 1 pediatric oncology trials offer only a small chance of direct benefit and may have significant risks and an impact on quality of life. To date, research has not examined discussions of risks and benefits during informed consent conferences for phase 1 pediatric oncology trials. The objective of the current study was to examine clinician and family communication about risks, benefits, and quality of life during informed consent conferences for phase 1 pediatric oncology trials. Methods Participants included clinician investigators, parents, and children recruited from 6 sites conducting phase 1 pediatric oncology trials. Eighty-five informed consent conferences were observed and audiotaped. Trained coders assessed discussions of risks, benefits, and quality of life. Types of risks discussed were coded (e.g., unanticipated risks, digestive system risks, death). Types of benefits were categorized as therapeutic (e.g. discussion of how participation may or may not directly benefit child), psychological, bridge to future trial, and altruism. Results Risks and benefits were discussed in 95% and 88% of informed consent conferences, respectively. Therapeutic benefit was the most frequently discussed benefit. The impact of trial participation on quality of life was discussed in the majority (88%) of informed consent conferences. Conclusion Therapeutic benefit, risks, and quality of life were frequently discussed. The range of information discussed during informed consent conferences suggests the need for considering a staged process of informed consent for phase 1 pediatric oncology trials.

Childhood Cancer and Brain Tumor Late Effects: Relationships with Family Burden and Survivor Psychological Outcomes

This study examines illness-specific family burden as a mediator of the association between late effects of childhood cancer and survivors’ emotional and behavioral outcomes. Childhood cancer survivors (n = 65; ages 10–17) two or more years off-treatment completed measures assessing internalizing and PTSD symptoms. Parents reported on illness-specific family burden, late effects severity, and survivor internalizing/externalizing problems. Providers documented the number of late effects. Illness-specific family burden was correlated with provider-reported late effects (r = .29, p < .05) and parent report of severe late effects (r = .56, p < .01). Results supported an indirect effect of illness-specific family burden on number of late effects and parent-reported survivor internalizing problems, p < .05. Indirect effects were not found in models predicting PTSD and externalizing problems. Illness-specific family burden is an important intervention target for reducing internalizing problems in childhood cancer survivors with late effects.
