Psychosocial risk and health care utilization in pediatric sickle cell disease.

INTRODUCTION: Pain and complications related to pediatric sickle cell disease (SCD) are associated with higher health care utilization. In other pediatric chronic conditions, psychosocial screening can help identify children and families at risk of increased health care utilization to guide resource allocation, address treatment needs, and improve care. This study aimed to investigate the utility of psychosocial screening in predicting increased health care utilization among youth with SCD. METHODS: Youth with SCD (n = 74, 8-18 years) and their parents were recruited from comprehensive SCD clinics. Parents completed the Psychosocial Assessment Tool (PAT), which categorized family psychosocial risk into one of three categories: Universal (minimal distress), Targeted (elevated distress), and Clinical (persistent distress). Youth reported on their pain characteristics, and health care utilization was extracted from medical chart review. Differences in health care utilization were evaluated using analysis of variance (ANOVA) and moderation analyses. RESULTS: Based on PAT risk, families were categorized into Universal (56.8%), Targeted (29.7%), and Clinical (13.5%) risk groups, with no significant group differences across demographic variables. Patients in the Targeted group reported significantly higher pain frequency than those in the Universal group (F[2, 66] = 3.7, p < .05). The association between pain frequency and health care utilization significantly varied on the basis of psychosocial risk, such that Clinical psychosocial risk strengthened the connection between pain frequency and health care utilization (ß = .2, t = 2.1, p < .05). CONCLUSIONS: Integrating the PAT into routine clinical care may help health care providers identify families in need of greater psychosocial or medical support to further optimize SCD management.

Parental Psychosocial Distress in Pediatric Sickle Cell Disease and Chronic Pain.

BACKGROUND: Pediatric sickle cell disease (SCD) management can result in considerable caregiver distress. Parents of youth with chronic SCD pain may face the additional challenge of managing children's chronic pain and chronic illness. This study examined associations between parent psychological distress and child functioning and the moderating role of chronic pain among youth with SCD. METHODS: Youth presenting to pediatric outpatient comprehensive SCD clinics and their primary caregivers completed a battery of questionnaires. Parents reported on parenting stress, parent mental and physical health, and family functioning. Children completed measures of pain characteristics, depressive symptoms, catastrophic thinking, functional disability, and quality of life. RESULTS: Patients (N = 73, Mage = 14.2 years, 57% female) and their caregivers (Mage = 41.1 years, 88% mothers, 88% Black) participated. Worse parent functioning was associated with worse child pain, functioning, quality of life, and depressive symptoms. Beyond the effects of SCD, chronic SCD pain magnified the negative associations between parenting stress frequency and child quality of life, parent physical health and child quality of life, and parent depressive symptoms and child depressive symptoms. CONCLUSIONS: Chronic pain may exacerbate the relations between parent and child functioning beyond the effects of SCD alone. The management of both SCD and chronic pain may present additional challenges for parents that limit their psychosocial functioning. Family-focused interventions to support parents and youth with chronic SCD pain are warranted to optimize health outcomes.

Correlates of Positive Parenting Behaviors.

The present study examined the influence of maternal and child characteristics on parenting behaviors in a genetically informative study. The participants were 976 twins and their mothers from the Colorado Longitudinal Twin Study and the Twin Infant Project. Indicators of positive parenting were coded during parent-child interactions when twins were 7-36 months old. Child cognitive abilities and affection were independent correlates of positive parenting. There were significant gender differences in the magnitude of genetic and environmental influences on positive parenting, with shared environmental influences on parenting of girls and additive genetic influences on parenting of boys. Girls received significantly more positive parenting than boys. Differences in etiology of positive parenting may be explained by developmental gender differences in child cognitive abilities and affection, such that girls may have more rewarding interactions with parents, evoking more positive parenting.

Childhood language development and later alcohol use behaviors.

BACKGROUND: Studies have shown a correlation between language abilities and alcohol use; however, results are inconsistent. A recent study using a discordant twin design showed an association between early child language development and later alcohol use behaviors; i.e., the twin with more advanced language abilities was more likely to try alcohol earlier in adolescence (Latvala et al., 2014). The authors suggested that this could result from better socialization of individuals with greater language abilities, which could lead to more opportunities for alcohol experimentation. The findings by Latvala et al. raise interesting questions, but the study has limitations, and replication is needed. METHOD: We aimed to replicate and build upon these results utilizing 488 same sex twin pairs from the Colorado Longitudinal Twin Study, a longitudinal sample with quantitative measures of language abilities starting when the twins were 14 months old. RESULTS: We found no significant correlations between a latent measure of child language abilities or measures of general cognitive ability at ages 14, 20, and 24 months and a latent alcohol use variable at ages 17 and 22 years. CONCLUSION: Our results did not replicate the association between early language ability and later alcohol use reported by Latvala et al. Possible reasons for differing results across samples, including varying cultural norms as well as differences in educational attainment, peer influences, and novelty seeking, were discussed.

Independent predictors of mortality in adolescents ascertained for conduct disorder and substance use problems, their siblings and community controls.

BACKGROUND AND AIMS: Adolescents with conduct and substance use problems are at increased risk for premature mortality, but the extent to which these risk factors reflect family- or individual-level differences and account for shared or unique variance is unknown. This study examined common and independent contributions to mortality hazard in adolescents ascertained for conduct disorder (CD) and substance use disorder (SUD), their siblings and community controls, hypothesizing that individual differences in CD and SUD severity would explain unique variation in mortality risk beyond that due to clinical/control status and demographic factors. DESIGN: Mortality analysis in a prospective study (Genetics of Antisocial Drug Dependence Study) that began in 1993. SETTING: Multi-site sample recruited in San Diego, California and Denver, Colorado, USA. PARTICIPANTS: A total of 1463 clinical probands were recruited through the juvenile correctional system, court-mandated substance abuse treatment programs and correctional schools, along with 1399 of their siblings, and 904 controls. MEASUREMENTS: Mortality and cause-of-death were assessed via National Death Index search (released October, 2017). FINDINGS: There were 104 deaths documented among 3766 (1168 female) adolescents and young adults (average age 16.79 years at assessment, 32.69 years at death/censoring). Mortality hazard for clinical probands and their siblings was 4.99 times greater than that of controls (95% confidence interval = 2.40-10.40; P < 0.001). After accounting for demographic characteristics, site, clinical status, familial dependence and shared contributions of CD and SUD, CD independently predicted mortality hazard, whereas SUD severity did not. CONCLUSIONS: In the United States, youth with conduct and substance use disorders and their siblings face far greater risk of premature death than demographically similar community controls. In contrast to substance use disorder severity, conduct disorder is a robust predictor of unique variance in all-cause mortality hazard beyond other risk factors.
