Assessing psychosocial functioning following childhood acquired brain injury: The Sydney Psychosocial Reintegration Scale for Children

A randomized controlled trial of cognitive behavioural therapy for managing anxiety in adolescents with acquired brain injury

The aim of this randomized controlled trial was to evaluate an adapted cognitive behavioural therapy (CBT) programme for treating anxiety in adolescents with acquired brain injury (ABI). Participants with ABI (12-19 years, N = 36) recruited from two sites were randomly allocated into either the intervention receiving 11 sessions of CBT (n = 19) or a wait-list control group (n = 17). The primary outcome was participants' anxiety and secondary outcomes were participants' depression, self-perception, and participation in daily activities, and parental stress, measured at (i) pre-intervention, (ii) immediately post-intervention, (iii) 2 months post-intervention and (iv) 6 months post-intervention. Repeated measures ANOVAs revealed significant treatment effects with the intervention group demonstrating greater improvements in self-reported anxiety, as well as self- and parent-reported depression from pre- to immediately post-treatment, compared to wait-list controls. Little evidence of treatment effects was found for the remaining outcomes (parent-reported anxiety, self-perception, daily participation, and parental stress). Significant improvement in self-reported anxiety found immediately post-treatment was maintained at two- and six-month follow-up. Findings provide support for adapted CBT as an effective means of reducing anxious and depressive symptomatology in adolescents with ABI compared to waitlist controls, and offer support for the use of these techniques to manage anxiety in this population.

Trait Mindfulness as a Mediator of Anxiety and Psychosocial Functioning in Young People with Acquired Brain Injury

Objective: Following acquired brain injury (ABI), young people may experience increased anxiety as well as difficulties with their psychosocial functioning. This study examined trait mindfulness as a mediator of the relationship between anxiety and psychosocial domains of School and Leisure Activities (SLA), Interpersonal Relationships (IR) and Daily Living Skills (DLS).Method: Participants were adolescents with ABI (aged 12-19 years, N = 38). Standardised measures were used to assess anxiety, trait mindfulness, and psychosocial functioning.Results: Higher levels of anxiety were found to be associated with reduced IR (p < .05) and DLS (p < .05). Increased trait mindfulness was found to be associated with lowered anxiety (p < .01), as well as with better IR (p < .05) and DLS (p <.01). Mediation analyses found a significant indirect effect for the relationship between anxiety and DLS through trait mindfulness.Conclusion: Findings highlight the contribution of trait mindfulness as a mediator between anxiety and psychosocial functioning, such that increased mindfulness and lower levels of anxiety are related to better DLS.

Social dysfunction after pediatric traumatic brain injury: A translational perspective

Social dysfunction is common after traumatic brain injury (TBI), contributing to reduced quality of life for survivors. Factors which influence the development or persistence of social deficits after injury remain poorly understood, particularly in the context of ongoing brain maturation during childhood and adolescence. Aberrant social interactions have recently been modeled in adult and juvenile rodents after experimental TBI, providing an opportunity to gain new insights into the underlying neurobiology of these behaviors. Here, we review our current understanding of social dysfunction in both humans and rodent models of TBI, with a focus on brain injuries acquired during early development. Modulators of social outcomes are discussed, including injury-related and environmental risk and resilience factors. Disruption of social brain network connectivity and aberrant neuroendocrine function are identified as potential mechanisms of social impairments after pediatric TBI. Throughout, we highlight the overlap and disparities between outcome measures and findings from clinical and experimental approaches, and explore the translational potential of future research to prevent or ameliorate social dysfunction after childhood TBI.
