Objectives: Children with acquired brain injury (ABI) can present with disruptive behavior, which is often a consequence of injury and parent factors. Parent factors are associated with child disruptive behavior. Furthermore, disinhibition in the child also leads to disruptive behavior. However, it is unclear how these factors interact. We investigated whether parental factors influence child disruptive behavior following ABI and how these factors interact. Methods: Parents of 77 children with ABI participated in the study. Parent factors (executive dysfunction, trait-anxiety), potential intervention targets (dysfunctional parenting practices, parental stress, child disinhibition), and child disruptive behavior were assessed. A hypothetical model based on the literature was tested using mediation and path analysis. Results: Mediation analysis revealed that child disinhibition and dysfunctional parenting practices mediated the association of parent factors and child disruptive behavior. Parents’ executive dysfunction mediated the association of dysfunctional parenting practices, parental stress and parent trait-anxiety. Parenting practices mediated the association of executive dysfunction and child disruptive behavior. Path analysis indices indicated good model adjustment. Comparative and Tucker-Lewis Index were >0.95, and the root mean square error of approximation was 0.059, with a chi-square of 0.25. Conclusions: A low level of parental trait-anxiety may be required to reduce dysfunctional parenting practices and child disinhibition. Impairments in child disinhibition can be exacerbated when parents present with high trait-anxiety. Child disinhibition is the major contributor of disruptive behavior reported by parents and teachers. The current study provides evidence of parent anxiety and child disinhibition as possible modifiable intervention targets for reducing child disruptive behavior. (JINS, 2019, 25, 237–248)

Childhood and adolescence coincide with rapid structural and functional maturation of brain networks implicated in Theory of Mind (ToM); however, the impact of paediatric traumatic brain injury (TBI) on the development of these higher order skills is not well understood. ToM can be partitioned into conative ToM, defined as the ability to understand how indirect speech acts involving irony and empathy are used to influence the mental or affective state of the listener; and affective ToM, concerned with understanding that facial expressions are often used for social purposes to convey emotions that we want people to think we feel. In a sample of 84 children with mild-severe TBI and 40 typically developing controls, this study examined the effect of paediatric TBI on affective and conative ToM; and evaluated the respective contributions of injury-related factors (injury severity/lesion location) and non-injury-related environmental variables (socio-economic status (SES)/family functioning) to long-term ToM outcomes. Results showed that the poorest ToM outcomes were documented in association with mild-complicated and moderate TBI, rather than severe TBI. Lesion location and SES did not significantly contribute to conative or affective ToM. Post-injury family affective responsiveness was the strongest and most significant predictor of conative ToM. Results suggest that clinicians should exercise caution when prognosticating based on early clinical indicators, and that group and individual-level outcome prediction should incorporate assessment of a range of injury- and non-injury-related factors. Moreover, the affective quality of post-injury family interactions represents a potentially modifiable risk factor, and might be a useful target for family-centred interventions designed to optimise social cognitive outcomes after paediatric TBI.

Children with traumatic brain injury (TBI) are at risk for social impairment. This study aimed to examine social function at 6 months post-TBI and to explore the contribution of injury, cognitive, and environmental influences. The sample included 136 children, 93 survivors of TBI, and 43 healthy controls. TBI participants were recruited on admission and underwent magnetic resonance imaging scan within 8 weeks of injury and behavioral assessment at 6 months post-injury. Healthy controls underwent magnetic resonance imaging scans and behavioral assessment on recruitment. Assessment included parent and child questionnaires tapping social outcome and child-direct testing of cognitive abilities important for social competence (communication, attention/executive function, social cognition). Injury characteristics and environmental measures were collected. At 6-months post-injury, social problems were evident, but not global. Social participation appeared most vulnerable, with more severe injuries leading to greater problems. Greater injury severity and poorer communication skills were associated with poorer social adjustment and social participation, with the impact of family function also significant. Processing speed, younger age, and male gender also contributed to social outcomes. Further follow-up is required to track the recovery of social skills and the changing influences of cognition, brain, and environment over time. (JINS, 2013, 19, 1–12)

Purpose: Traumatic brain injury (TBI) often leads to executive functions deficits, which may be responsible for severe and longstanding disabilities in everyday activities. Sensitivity and ecological validity of neuropsychological tests of executive functions have been questioned. The aims of this study were to pilot an ecological open-ended assessment of executive functions in children, the ‘Children's Cooking Task’ (CCT), specifically to report its reliability, discriminant validity and concurrent validity. Methods: Twenty-five children with mild (n = 10) or moderate-to-severe TBI (n = 15), and 21 matched controls (aged 8 to 20 years) participated in the study. An open-ended cooking task was designed to test multi-tasking abilities. It required the preparation of two simple recipes using specific instructions. Outcome measures included the number of errors and an overall qualitative analysis of the task. Validating measures of executive functions included the Delis Kaplan Executive Function System, the Six-Part Test and two questionnaires completed by the child's primary care-giver: the Behavior Rating Inventory of Executive Function and the Dysexecutive Questionnaire for Children. Results: Internal consistency of the Children's Cooking Task was high (Cronbach's alpha = .86), as was test–retest reliability (ICC = .89). Children with moderate-to-severe TBI, as well as children with mild TBI made significantly more errors in the Children's Cooking Task in comparison to controls (p < .001). The CCT was correlated with several tests and one questionnaire of executive functioning (Trails, verbal fluency, sorting, 20 questions, Dysexecutive Questionnaire). Discussion and Conclusion: The Children's Cooking Task has good interrater and test–retest reliability, as well as good discriminant and concurrent validity.

Recently, there has been a surge of interest and research in social functioning throughout childhood and adolescence, and how social development is affected by acquired brain injury (ABI). Despite ongoing research and theoretical advances, there remains a lack of specific, relevant and robust measurement tools that draw upon current clinical and social neuroscience knowledge, and which are developmental in nature, to assess social competence within the nonclinical and the ABI population. The aim of the current project was to develop a questionnaire to measure social competence and the quality of relationships of children and adolescents between the ages of 5 and 18 years. This questionnaire, the Developmental Assessment of Social Competence (DASC), also aimed to be sensitive to the specific social problems often associated with children who have suffered ABI. The current article outlines the process and challenges faced in developing such a measure up to the initial pilot stage. Participants included a pilot group of 40 parents who completed the pilot questionnaire, as well as an established questionnaire that assesses social functioning. Parents rated their own children who were aged between 6 and 14 years, and who were within the nonclinical population. Preliminary analyses found that the children generally scored highly on the DASC, and that a higher score on most scales of the DASC tended to be associated with a higher score on an established questionnaire measuring social skills. These data are promising, and provide important information for the following stages of development and evaluation of this new questionnaire.

Limited research has investigated specific attentional sequelae following pediatric traumatic brain injury (TBI), such as sustained, selective, and shifting attention, as well as speed of processing. Little is known about the pattern of recovery of these skills or their interaction with ongoing development. The present study examined attentional abilities at acute, 6-, 12-, and 24-month time points postinjury in a group of 71 children who had sustained a mild, moderate, or severe TBI. Results indicated that children who sustained a severe TBI generally performed poorest, but showed most recovery over time. The pattern of recovery was dependent on the attentional component being measured. Specifically, deficits were most evident on more complex and timed tasks. While a number of areas showed recovery over time, for some attentional components, difficulties persisted to 24 months postinjury. (JINS, 2005, 11, 84–98.)

Little is known about specific attentional sequelae following a closed head injury, their pattern of recovery or their interaction with ongoing development. The present study examined attentional abilities in a group of children who had sustained a mild, moderate, or severe head injury. Results showed that the severe head injury group exhibited greater deficits on a number of attentional measures at acute and 6 months postinjury phases, in comparison to children in the mild and moderate head injury groups. Specifically, deficits were most evident on timed tasks where speed of processing was an integral component. Difficulties persisted to at least 6 months postinjury and so may lead to cumulative deficits over time. (JINS, 1999, 5, 48–57.)

It has been argued that young children's brains are “plastic,” and may sustain substantial brain insult with little loss of function. Recent research suggests that this notion may not apply for generalized cerebral pathology. The present study aimed to evaluate this proposition using a sample of 73 young children, divided into 3 groups: severe head injury (HI; N = 17); mild–moderate HI (N = 32); and noninjured controls (N = 24). Preinjury screening established equivalence across groups for age, sex, preinjury ability, behavioral adjustment, socioeconomic status, and family functioning. Children were evaluated as soon as possible postinjury, and again 12 months postinjury, in three domains: intellectual ability, language, and memory. Results indicated that severe HI was associated with substantial, persisting difficulties in all areas. In contrast, children with mild–moderate HI experienced fewer difficulties, and often performed similarly to controls, both acutely and 12 months postinjury. There was no evidence of differential recovery of function associated with injury severity, with performance increments consistent across groups and probably due to either age-appropriate developmental gains, or test–related practice effects. Poorer outcome at 12 months postinjury was predicted by injury severity primarily, with earlier age at injury, and premorbid ability associated with outcome in specific domains.

This study compared postmeningitic children (N = 130) with grade and sex matched controls (N = 130) selected from target children's schools on measures of intellectual, linguistic, learning, and reading skills. Results showed that children with a history of meningitis are at greater risk for impairment in these areas, with experience of the disease prior to 12 months of age being an important risk factor. Within the postmeningitic sample presence of medical complications was associated with poorer verbal abilities. Finally, a significant relationship was identified between depressed language skills and later educational difficulty, with these findings interpreted with respect to both developmental and neuropsychological principles.
