WHAT'S KNOWN ON THIS SUBJECT: After mild traumatic brain injury, most youth recover well. A minority of patients report persistent symptoms, which relate to both injury and noninjury factors. In adult studies, validity test performance is 1 noninjury factor that relates to persistent symptoms.

The ongoing Zika virus (ZIKV) epidemic in Latin America presented a unique opportunity to develop a neurodevelopmental assessment protocol for children in a lower middle-income country. Although studies of neurodevelopment in young children have taken place in many diverse global settings, we are not aware of any study that has provided a high level of detail about how a measure was selected and then specifically translated and adapted in a lowresource setting. Here, we describe considerations in measurement selection and then the process of translation and adaptation to assess neurodevelopmental outcomes of infants and young children with postnatal exposure to ZIKV in rural Guatemala. We provide a framework to other research teams seeking to develop similar assessment models across the globe.

Background: Children in low-and lower middle income countries (LMICs) often have poorer language skills compared with children from high-income countries. Limited availability of culturally and linguistically appropriate assessment measures in LMICs, especially for young children, can hinder early identification and prevention efforts. Here, we describe receptive language (RL) skills among young children in rural Guatemala and report on the validity of a translated and culturally adapted developmental measure of RL. Methods: Children (n = 157; m = 53.6 months, range = 42-68 months) enrolled in a prospective cohort study of postnatally acquired Zika virus infection were administered the Test de Vocabulario en Imagenes Peabody (TVIP) and the RL scale from a translated and adapted version of the Mullen Scales of Early Learning (MSEL). Performance on the TVIP was compared with the Latin American normative sample. Correlational analysis examined the relationship between performance on the TVIP and the MSEL-RL.Results: Mean scores were significantly below the normative sample mean on the TVIP, t(126) = −11.04, p < .001; d = 1.00. Performance on the TVIP among children who passed the practice items (n = 127) was significantly positively associated with performance on the MSEL-RL (r = .50, p < .001), but not significantly associated with age or gender. Older age (p < .0001) and female gender (p = .018) were associated with passing the TVIP practice items. Conclusions: Delays in RL vocabulary were identified among young children in rural Guatemala on the TVIP. The association between scores on the TVIP and the RL scale of the MSEL provides preliminary support for the construct validity of this translated and adapted version of the MSEL. Edwin J. Austrias and Flor M. Muñoz are co-senior authors.

Few studies have focused on consumer satisfaction following neuropsychological evaluation. We sought to examine parent satisfaction with neuropsychological consultation following a mild traumatic brain injury (TBI) in school-age children. We surveyed 71 parents of 8- to 17-year-olds participating in a prospective longitudinal study examining neuropsychological consultation as an intervention for persistent postconcussive symptoms. Children had sustained injuries between 2 and 12 months prior to enrollment. Neuropsychological consultation occurred on average 5 months post-injury. Parent satisfaction data were collected via telephone approximately 4 months after the neuropsychological consultation. The vast majority of parents were quite satisfied with the service (e.g., 94% overall satisfaction rate; 96% rated the service as good or excellent). Satisfaction rates were associated positively with time since injury and negatively with parental education. No other child, parent, or provider variable correlated with satisfaction. The results add to the relatively sparse literature on parent satisfaction with neuropsychological evaluation. A pressing future need in pediatric neuropsychology is to examine the satisfaction of other consumers of the service, including healthcare personnel, educators, and the child patients themselves.

This study aimed to characterize preinjury emotional-behavioral functioning in pediatric patients with lingering problems after mild traumatic brain injury (TBI). The clinical case series design included 278 patients 8-17 years old. Parents retrospectively rated children's preinjury emotional-behavioral functioning on a broadband questionnaire. The rate of clinically significant preinjury anxiety was elevated compared with national norms. The number of previous TBIs was associated with clinically significant preinjury externalizing problems, suggesting a link between externalizing disorders and mild TBI exposure. Premorbid emotional-behavioral difficulties may play an important role in the establishment or maintenance of lingering symptoms after pediatric mild TBI.

The current study lends preliminary support to the idea that the identification and communication of invalid performance can be a beneficial clinical intervention that promotes high levels of caregiver satisfaction and a reduction in self-reported and caregiver-reported symptoms.
