OBJECTIVE: The long-term consequences of traumatic brain injury (TBI) on brain structure remain uncertain. Given evidence that a single significant brain injury event increases the risk of dementia, brain-age estimation could provide a novel and efficient indexing of the long-term consequences of TBI. Brain-age procedures use predictive modeling to calculate brain-age scores for an individual using structural magnetic resonance imaging (MRI) data. Complicated mild, moderate, and severe TBI (cmsTBI) is associated with a higher predicted age difference (PAD), but the progression of PAD over time remains unclear. We sought to examine whether PAD increases as a function of time since injury (TSI) and if injury severity and sex interacted to influence this progression. METHODS: Through the ENIGMA Adult Moderate and Severe (AMS)-TBI working group, we examine the largest TBI sample to date (n = 343), along with controls, for a total sample size of n = 540, to replicate and extend prior findings in the study of TBI brain age. Cross-sectional T1w-MRI data were aggregated across 7 cohorts, and brain age was established using a similar brain age algorithm to prior work in TBI. RESULTS: Findings show that PAD widens with longer TSI, and there was evidence for differences between sexes in PAD, with men showing more advanced brain age. We did not find strong evidence supporting a link between PAD and cognitive performance. INTERPRETATION: This work provides evidence that changes in brain structure after cmsTBI are dynamic, with an initial period of change, followed by relative stability in brain morphometry, eventually leading to further changes in the decades after a single cmsTBI.

BACKGROUND: The job interview can be challenging for autistic adolescents considering the required social communication skills. Further, having decreased awareness of personal strengths may make it difficult to advocate for oneself to a future employer. The purpose of the current pilot randomized controlled trial (RCT) is to examine the preliminary efficacy and feasibility of a combined interventional approach using: the Virtual Interview Tool for Autistic Transition-Age Youth (VIT-TAY) and Kessler Foundation Strength Identification and Expression (KF-STRIDE). METHOD: Twenty autistic transition-age youth (TAY) were randomly assigned to two groups: an intervention group (n = 10) that received 9 h of VIT-TAY (interviewing practice with a virtual human), and three lessons of KF-STRIDE (positive psychology intervention to learn and discuss one's personal character strengths) and a services-as-usual (SAU) group (n = 10). The primary outcome was measured using a video-recorded mock job interview performed at pre- and post-test, which was rated by blinded assessors. Secondary outcomes included self-reports of job interview skill, interview anxiety, work readiness and recent job search behavior. RESULTS: Paired samples t-tests revealed significant differences between pre- and post-test in the intervention group (but not the control group) on the mock interview total score (p = 0.02, d = 0.76) and self-reported job interview skills total score (p = 0.02, d = 0.75). The intervention group (but not the control group) had improvements in work-readiness (p = 0.06, d = 0.53) and job search behavior (p = 0.07, d = 0.52) that were characterized by medium effect sizes. CONCLUSIONS: This pilot study suggests that combining VIT-TAY with KF-STRIDE leads to improvements in performance-based and self-reported job interview skills.
RÉSUMÉ
BACKGROUND: The study of job interview training is an emerging area among transition-age autistic youth who face significant challenges when navigating job interviews. The autism field has limited measures that have undergone rigorous psychometric evaluation. OBJECTIVE: We sought to evaluate the psychometric properties of adapted self-report measures assessing job interview skills and job interview anxiety. METHODS: As part of two parent randomized controlled trials, eighty-five transition-age autistic youth completed measures related to the strength of their job interview skills and their level of job interview anxiety. We conducted classical test theory analyses, exploratory and confirmatory factor analyses, and Rasch model analytic and calibration analyses. Pearson correlations were used to establish concurrent, divergent, and criterion validity by correlating these scales with measures of social differences, depressive symptoms, behaviors, neuropsychological functioning, and work history. RESULTS: Our analyses yielded two brief and reliable scales: Measure of Job Interview Skills (MOJO-iSkills) and Measure of Job Interview Anxiety (MOJO-iAnxiety), which demonstrated initial concurrent, divergent, and criterion validities when correlated with measures of depressive symptoms, social differences, internalizing and externalizing behavior, and work history. CONCLUSIONS: This study presents initial evidence that MOJO-iSkills and MOJO-iAnxiety have acceptable psychometric properties supporting they can be used to reliably and validly assess job interview skills and interview anxiety.
