Abstract
OBJECTIVE To evaluate the efficacy and costs of a brief, group-delivered parenting intervention for families of children with eczema. METHODS A randomized controlled trial design was used. Families attending the Queensland Children's Hospital and from the community (n = 257) were assessed for eligibility (child 2-10 years, diagnosed with eczema, prescribed topical corticosteroids). Families who consented to participate (N = 59) were assessed at baseline for clinician-rated eczema severity, parent-reported eczema symptom severity, and electronically-monitored topical corticosteroid adherence (primary outcomes); and parenting behavior, parents' self-efficacy and task performance when managing eczema, eczema-related child behavior problems, and child and parent quality of life (secondary outcomes). Families were randomized (1:1, unblinded) to intervention (n = 31) or care-as-usual (n = 28). The intervention comprised two, 2-hr Healthy Living Triple P group sessions (face-to-face/online) and 28 intervention families attended one/both sessions. All families were offered standardized eczema education. Families were reassessed at 4-weeks post-intervention and 6-month follow-up, with clinician-raters blinded to condition. Costs of intervention delivery were estimated. RESULTS Multilevel modeling across assessment timepoints showed significant intervention effects for ineffective parenting (d = .60), self-efficacy (d = .74), task performance (d = .81), and confidence with managing eczema-related child behavior (d = .63), but not disease/symptom severity, treatment adherence or quality of life. Mean cost per participating family with parenting behavior (clinically) improved was $159. CONCLUSIONS Healthy Living Triple P is effective in reducing ineffective parenting practices and improving parents' self-efficacy and task performance when managing children's eczema and eczema-related behavior difficulties. There was no effect on disease/symptom severity, treatment adherence, or quality of life. CLINICAL TRIAL REGISTRATION ACTRN12618001332213.

Abstract
OBJECTIVES Neurofibromatosis type 1 (NF1) is a genetic cancer predisposition syndrome that can impact multiple organ systems and is associated with plexiform neurofibroma tumors, requiring care from birth through adulthood. Adolescents and young adults (AYAs) with NF1 face several barriers to transition from pediatric to adult care. This cross-sectional study aimed to assess transition readiness in this population and to evaluate relationships between specific NF1 symptoms and transition readiness. METHODS AYAs (aged 16-24) enrolled in existing studies related to NF1 were eligible. AYAs and their parents completed measures of transition readiness (Transition Readiness Assessment Questionnaire version 4 [TRAQ-4]), and AYAs also completed a transition readiness interview (UNC TRxANSITION). RESULTS Thirty-eight AYAs (mean age = 19.95 ± 2.68 years) participated in the study. Average TRAQ scores indicated that AYAs were still learning Self-Management skills (M = 3.37, SD = 1.08) and Self-Advocacy skills (M = 3.98, SD = 0.67). Older AYAs had higher TRAQ scores for Self-Management (r = 0.70, p < .001) and Self-Advocacy (r = 0.41, p = .011) than younger AYAs. Parents and AYAs had similar TRAQ scores. About one third of AYAs (37.8%, n = 14) expressed uncertainty about how NF1 might affect them in the future. The remaining AYAs mostly expressed concerns regarding tumor growth, pain, or cancer. CONCLUSIONS In this small study, preliminary findings suggest that AYAs with NF1 express confidence in many areas of transition readiness but continue to require support, particularly with Self-Management skills. Given the gaps in understanding of future health risks, AYAs with NF1 would benefit from early assessment, psychoeducation, and support for transition readiness to adult care.

Abstract
OBJECTIVE Examine preventive medication adherence among youth with migraine. METHODS Adherence (self-report, pill count, and blood serum drug levels) was assessed as an ancillary study that utilized data from 328 CHAMP Study participants (ages 8-17). CHAMP was a multisite trial of preventive medications. Participants completed a prospective headache diary during a six-month active treatment period during which youth took amitriptyline, topiramate, or placebo pill twice daily. Self-reported medication adherence was collected via daily diary. At monthly study visits, pill count measures were captured. At trial month 3 (trial midpoint) and 6 (end of active trial), blood serum drug levels were obtained. Self-report and pill count adherence percentages were calculated for the active trial period, at each monthly study visit, and in the days prior to participants' mid-trial blood draw. Percentages of nonzero drug levels were calculated to assess blood serum drug level data. Adherence measures were compared and assessed in context of several sociodemographic factors. Multiple regression analyses investigated medication adherence as a predictor of headache outcomes. RESULTS Self-report and pill count adherence rates were high (over 90%) and sustained over the course of the trial period. Serum drug level adherence rates were somewhat lower and decreased significantly (from 84% to 76%) across the trial period [t (198) = 3.23, p = .001]. Adherence measures did not predict headache days at trial end; trial midpoint serum drug levels predicted headache-related disability. CONCLUSIONS Youth with migraine can demonstrate and sustain relatively high levels of medication adherence over the course of a clinical trial.

Abstract
OBJECTIVE A previously published exploratory factor analysis suggested that the Hypoglycemia Fear Survey-Child and Parent Versions, is comprised of three subscales: Maintain High Blood Glucose, Helplessness/Worry About Low Blood Glucose, and Worry About Negative Social Consequences. The primary aim of this study was to confirm this three-factor model with a clinical population of adolescents with type 1 diabetes (T1D) and their caregivers. METHODS Participants included N = 1,035 youth ages 10-17.99 years with T1D, and their female (N = 835) and/or male (N = 326) caregivers who completed the Hypoglycemia Fear Survey independently during a routine medical appointment. We conducted confirmatory factor analysis and examined reliability of the Hypoglycemia Fear Survey and its associations with demographics and clinical outcomes (e.g., mean blood glucose, glycemic control). RESULTS Confirmatory factor analysis supported the three-factor model in youth and female and male caregivers. The internal consistencies for Maintain High Blood Glucose, Helplessness/Worry About Low Blood Glucose, and Worry About Negative Social Consequences were acceptable. The majority of demographic and clinical outcome variables correlated as hypothesized with the three subscales. CONCLUSIONS Using a large clinical sample of adolescents with T1D and their caretakers, we confirmed the three-factor model for the Hypoglycemia Fear Survey, which is sufficiently reliable to be used in a clinical setting. Important areas of future research include examining moderators for the effect of fear of hypoglycemia on clinical outcomes, and possible inclusion of items related to modern diabetes devices.

Abstract
OBJECTIVE The primary goal of this study was to examine the factor structure of a spina bifida (SB) medical responsibilities measure and a medical regimen skills scale across time in families of youth with SB. METHOD One-hundred and forty youth with SB and their parents were assessed in both childhood/adolescence and adolescence/young adulthood. The Sharing of SB Medical Responsibilities Scale (SOSBMR) includes 34 items for which participants indicate who is responsible for each task. The SB Independence Survey (SBIS) is composed of 50 SB-specific medical skills items in yes-no format. Confirmatory factor analyses (CFA) were conducted to examine the factor structure of the SOSBMR and SBIS in childhood and adolescence (ages 8-15) and in adolescence/young adulthood (AYA; ages 16-25). RESULTS One- and seven-factor CFAs were compared for both measures. For the SBIS, both mother- and father-report were used in childhood; self-report was employed for AYA. For the SOSBMR, only self-report was used for both age groups. Across each rater and time point, the seven-factor models of the SBIS and SOSBMR had adequate to excellent fit and reliability, indicating the ability to use each subscale. In addition, each of the corresponding subscales on the SOSBMR and SBIS were associated with each other across raters and time, showing good concurrent and predictive validity. CONCLUSIONS From childhood to young adulthood, the subscales of the SOSBMR can be used to examine responsibility across multiple medical tasks and the SBIS can be used to assess medical regimen skills and mastery in young people with SB.

Abstract
OBJECTIVE To replicate the factor structure of a patient-report measure of provider communication about key medication prescription information, the Communication about Medication by Providers-Adolescent and Young Adult (CAMP-AYA) Version. We evaluated whether the 15-item, two-factor structure identified previously could be replicated via confirmatory factor analysis, and we also examined fit of unidimensional and bifactor models. Associations of CAMP-AYA Total and Factor Scores with provider satisfaction and select patient and medication characteristics were also examined. METHODS Participants were 739 AYA (ages 18-25) who completed the CAMP-AYA, a provider satisfaction rating, and provided demographic and medication information. RESULTS The bifactor model was best fitting (χ2 [75] = 689.60, p < .0001; root mean squared error of approximation = 0.11, 90% CI [0.10, 0.11]; Comparative Fit Index = 0.98; Tucker-Lewis Index = 0.98; Standardized Root Mean Square Residual Index = 0.02). Internal consistency reliabilities for Total and Factor Scores were high (αs > .89) and Total and Factor Scores were associated with provider satisfaction (ps < .001). CAMP-AYA scores varied as a function of type of prescription (short vs. long term; new vs. refill), with higher scores reported in the context of long term (>30-day course) or refilled prescriptions (ps < .007) in most cases. CONCLUSIONS This study provides additional support for the reliability of the CAMP-AYA as a tool to assess AYA perceptions of provider key information coverage about medication prescriptions.

Abstract
OBJECTIVE Following the Journal of Pediatric Psychology's special edition on health disparities, calling for Phase 2 research exploring mechanisms of racial groups in health disparities, this study aims to explore social information processing predictors of longitudinal hemoglobin A1c (HbA1c) trajectories in a racially diverse group of adolescents. The social information processing model of glycemic control in type 1 diabetes (T1D) posits that adolescents who make negative attributions about reactions of friends are likely to find adherence difficult in social situations, have increased stress, and have suboptimal glycemic control. METHODS One hundred eighty-four youth with T1D completed self-report measures and HbA1c at three time points within 1 year was extracted from medical records. Growth mixture modeling empirically derived classes of HbA1c trajectories and explored predictive relationships of social information processing variables, demographics, and diabetes characteristics. RESULTS Three classes emerged: High Decelerating, Mid-High Accelerating, and Near-Optimal Accelerating. Black/African American participants were highly likely to be in the High and Mid-High groups. Higher anticipated adherence difficulties in social situations predicted increased odds of being in the Mid-High versus Near-Optimal HbA1c group. Increased diabetes stress predicted increased odds of being in the High versus Near-Optimal and Mid-High groups. CONCLUSIONS Continuing research on mechanisms behind this health disparity is necessary with more representation from varied racial and ethnic groups. Equal access to diabetes technology and psychosocial treatments are recommended and implications for clinical intervention development are discussed.

Abstract
OBJECTIVE To examine the predictive role of social skills in youth with spina bifida (SB) on growth in medical responsibility across development. METHODS As part of a larger, longitudinal study, 140 youth with SB were assessed across four time points (ages 8-22 across time points). Mixed-effects models were investigated for change with: (a) no predictors (i.e., change in medical responsibility across age; time was examined using the participant's age, centered at 11.5 years); (b) social variables (i.e., observed social behaviors, parent- and teacher-reported social skills) as predictors; and (c) social variables as predictors with intelligence quotient, lesion level, and sex as covariates. RESULTS Significant growth with age was identified for medical responsibility (p < .0001). Observed, parent-reported, and teacher-reported social skills did not significantly predict this growth; however, all three predicted the intercept for medical responsibility at 11.5 years of age (ps ≤ .047). Parent-reported social skills remained a significant predictor of the intercept at 11.5 years of age when including the covariates (p = .008). CONCLUSIONS Children with SB who exhibited more positive social skills were more likely to a have higher level of medical responsibility in late childhood, but higher levels of social skills were not associated with a more rapid increase in responsibility over time. Identifying existing social strengths and promoting the practice of prosocial skills may have additional benefits to children with SB, including their acquisition of medical responsibility.

Abstract
OBJECTIVE This article guides researchers through the process of specifying, troubleshooting, evaluating, and interpreting latent growth mixture models. METHODS Latent growth mixture models are conducted with small example dataset of N = 117 pediatric patients using Mplus software. RESULTS The example and data show how to select a solution, here a 3-class solution. We also present information on two methods for incorporating covariates into these models. CONCLUSIONS Many studies in pediatric psychology seek to understand how an outcome changes over time. Mixed models or latent growth models estimate a single average trajectory estimate and an overall estimate of the individual variability, but this may mask other patterns of change shared by some participants. Unexplored variation in longitudinal data means that researchers can miss critical information about the trajectories of subgroups of individuals that could have important clinical implications about how one assess, treats, and manages subsets of individuals. Latent growth mixture modeling is a method for uncovering subgroups (or "classes") of individuals with shared trajectories that differ from the average trajectory.

Abstract
OBJECTIVE Adherence to asthma controller medications is suboptimal among adolescents. We evaluated predictors of adherence and longitudinal patterns of medication use between 8th and 10th grade among a sample of youth of diverse race/ethnicity. METHODS Eighth graders with asthma on controller medications (N = 62; 40.0% non-Latino white; 23.7% Black; 37.3% Latino; 37.3% female) completed measures of medication beliefs, responsibility for asthma management, and family cohesion. Objective methods tracked medication use longitudinally. RESULTS Adherence declined during the high school transition, from 48.0% in eighth grade to 34.1% in tenth grade (F = 5.35, p < .01). Males had lower adherence (b = -10.11, SE = 5.37, p = .02, f2 = 0.11), as did Latino youth (b = -12.21, SE = 8.23, p = .03, f2 = 0.12). Family cohesion was associated with higher adherence (b = 4.38, SE = 1.98, p = .04, f2 = 0.06). Latent class models (LCMs) suggested a three-class model of longitudinal adherence patterns. This included low, declining adherence (Class 1 = 29%; higher proportion male, p = .02), high, sustained adherence (Class 2 = 26%, high family cohesion, p = .05, higher proportion female, p = .02), and low, sustained adherence (Class 3 = 45%; higher proportion Latino, p = .05, higher proportion male, p = .02). CONCLUSIONS Asthma medication adherence declined between 8th and 10th grade. LCMs indicated some youth have stable patterns of adherence (high or low), whereas others demonstrate declines. Gender differences were observed, and family cohesion was associated with higher, sustained adherence. Interventions building on family resources and targeting the barriers adolescents face are necessary to improve asthma management during this vulnerable period.
