The genetic precursors and the advantageous and disadvantageous sequelae of inhibited temperament: an evolutionary perspective.

ABSTRACT: Guided by evolutionary game theory (Korte, Koolhaas, Wingfield, & McEwen, 2005), this study aimed to identify the genetic precursors and the psychosocial sequelae of inhibited temperament in a sociodemographically disadvantaged and racially diverse sample (N = 201) of 2-year-old children who experienced elevated levels of domestic violence. Using a multimethod, prospective design across 3 annual measurement occasions, the authors conducted structural equation modeling analyses indicating that trained observer ratings of inhibited temperament at age 2 were uniquely predicted by polymorphisms in dopamine and serotonin transporter genes. Children's inhibited temperament, in turn, indirectly predicted decreases in their externalizing problems at age 4 through its association with greater behavioral flexibility at age 3. Results highlight the value of integrating evolutionary and developmental conceptualizations in more comprehensively charting the developmental cascades of inhibited temperament.

Project description:Critical neurologic disease and injury affect thousands of children annually with survivors suffering high rates of chronic morbidities related directly to the illness and to critical care hospitalization. Postintensive care syndrome (PICS) in patients and families encompasses a variety of morbidities including physical, cognitive, emotional, and psychological impairments following critical care. We conducted a focus group study with parents of children surviving pediatric neurocritical care (PNCC) for traumatic brain injury, stroke, meningitis, or encephalitis to determine outcomes important to patients and families, identify barriers to care, and identify potential interventions to improve outcomes. Sixteen parents participated in four groups across Oregon. Three global themes were identified: (1) PNCC is an intense emotional experience for the whole family; (2) PNCC survivorship is a chronic illness; and (3) PNCC has a significant psychological and social impact. Survivors and their families suffer physical, emotional, psychological, cognitive, and social impairments for many years after discharge. Parents in this study highlighted the emotional and psychological distress in survivors and families after PNCC, in contrast to most PNCC research focusing on physical outcomes. Several barriers to care were identified with potential implications on survivor outcomes, including limited pediatric resources in rural settings, perceived lack of awareness of PICS among medical providers, and the substantial financial burden on families. Parents desire improved education surrounding PICS morbidities for families and medical providers, improved communication with primary care providers after discharge, access to educational materials for patients and families, direction to mental health providers, and family support groups to assist them in dealing with morbidities and accessing appropriate resources. Clinicians and researchers should consider the parent perspectives reported here when caring for and evaluating outcomes for children requiring PNCC.
