Lessons Learned From a Randomized Controlled Trial of a Family-Based Intervention to Promote School Functioning for School-Age Children With Sickle Cell Disease.

OBJECTIVE: Tested a family-based group problem-solving intervention, "Families Taking Control," (FTC) to improve school functioning and health-related quality of life (HRQL) for children with sickle cell disease. METHOD: Children and caregivers completed questionnaires assessing HRQL and school functioning and children completed performance-based measures of IQ and achievement at baseline and 6 months later. Families were randomized to the intervention (FTC, n = 42) or delayed intervention control (DIC, n = 41) group. FTC involved a full-day workshop followed by 3 booster calls. RESULTS: There were no differences between FTC completers (n = 24) and noncompleters (n = 18). FTC group (n = 24) and DIC group (n = 38) did not differ significantly on primary outcomes at follow-up: number of formal academic and disease-related accommodations, individualized education plan/504 service plan, school absences, school HRQL, or academic skills. CONCLUSIONS: Although families found FTC to be acceptable, there were no intervention effects. Challenges of the trial and implications for future research are discussed.

Insurance status as a sociodemographic risk factor for functional outcomes and health-related quality of life among youth with sickle cell disease.

Youth with sickle cell disease (SCD) are at risk for functional limitations and poor health-related quality of life (QoL). This study examined sociodemographic factors that may interact with medical complications to reduce functional ability and QoL among youth with SCD. Fifty-three patient/caregiver pairs (children 8 to 18 years; M=12.3 y) with SCD completed the Functional Disability Inventory and Pediatric Quality of Life Inventory questionnaires. Medical database reviews were conducted to collect health care utilization, disease complications, and sociodemographic information; insurance type (public vs. private insurance) and family zip code to access Census tract data reflecting neighborhood distress. Insurance type, but not neighborhood sociodemographic risk indicators, was significantly associated with disease-related complications and QoL. There were significant differences in both health care utilization and QoL by insurance type. Complications were higher in the group with public insurance. Insurance type seems to be more strongly related to disease outcomes and QoL than neighborhood sociodemographic distress. Closer attention to the contribution of insurance type to health outcomes may provide important insight to potential barriers for disease management. These issues are critically important for health care efficiency and equity for poor and underserved children with chronic health conditions.

Health-related quality of life and adaptive behaviors of adolescents with sickle cell disease: stress processing moderators.

The objective of this study was to examine resilience among adolescents with sickle cell disease (SCD), focusing on the interaction of health-related quality of life with stress processing to explain adaptive behavior. Forty-four adolescents with SCD completed paper-and-pencil measures of health-related quality of life, appraisals (hope), pain coping strategies (e.g. adherence), and adaptive behavior. Self-reported health-related quality of life was significantly associated with adaptive behavior, as was adherence. Findings for moderation were mixed. Pain coping strategies moderated the association of health-related quality of life with adaptive behavior such that at lower levels of Coping Strategies Questionnaire (CSQ) Adherence, better quality of life was associated with higher adaptive behavior. Similarly, at higher levels of hope, better quality of life was associated with higher adaptive behavior, and poorer quality of life was associated with lower adaptive behavior. Adolescents with SCD showed resilience, particularly in terms of personal adjustment, that may be explained by their appraisals and stress processing strategies. Interventions to support an optimistic or hopeful outlook and improve adherence to recommendations for medical management of sickle cell pain may result in improved resilience/adaptive behavior.

Initial development of a questionnaire evaluating perceived benefits and barriers to pediatric clinical trials participation.

OBJECTIVE: To evaluate perceived benefits and barriers to pediatric clinical trials participation to improve decision-making and enhance recruitment and retention among minority youth with chronic health conditions (sickle cell disease, asthma) and their caregivers. METHODS: A questionnaire was developed based on the social ecological model using input from medical experts and community-based public health organizations. Parallel caregiver, adolescent/young adult (AYA; 16-39 years old), and child (8-15 years old) versions were field tested. Patients and caregivers completed the questionnaire, which included demographic items, perceived life stress and social desirability measures. RESULTS: Exploratory factor analysis rendered a four-factor solution for the caregiver version (direct treatment benefit, mistrust of research/researchers, trust in healthcare team to engage in safe research, and opportunity cost) and the AYA version (mistrust/no direct benefit, safety, direct treatment benefit/practical considerations, and social support for research). Factor structures differed for SCD and asthma caregivers; results were equivocal for the child version. Summated subscales were not significantly associated with patient demographics or social desirability, but significant correlations with perceived life stress and prior participation in research were identified. CONCLUSIONS: While the factor structure should be confirmed with larger samples, findings indicate potential benefit, perceived harm due to mistrust of researchers, and logistics are primary factors in decision-making about participation in pediatric clinical trials. By addressing these benefits/barriers through adjustments to recruitment and informed consent procedures, researchers may address misperceptions of research, improve decision-making, and increase recruitment and retention particularly for ethnic minority children with chronic health conditions.
