Factors predictive of psychiatric outcome in the second 6 months following traumatic brain injury (TBI) in 43 children and adolescents were assessed prospectively. The outcome measure was the presence of a psychiatric disorder not present before the injury ("novel"). Out of six models tested, four were predictive of novel psychiatric disorder: preinjury family function, family psychiatric history, socioeconomic class/intellectual function, and behavior/adaptive function. Post hoc analyses suggested that preinjury family functioning measured by a structured interview was a significant predictive variable. Severity of injury, when reclassified as severe versus mild/moderate TBI, significantly predicted novel psychiatric disorders. These data suggest that some children, identifiable through clinical assessment, are at increased risk for psychiatric disorders following TBI.     

Evidence for genetic heterogeneity supports clinical differences in congenital myasthenic syndromes

Our goal was to prospectively study the course of oppositional defiant disorder (ODD) symptomatology in children and adolescents in the first 2 years after traumatic brain injury (TBI). Fifty children aged 6 to 14, hospitalized after TBI, were assessed soon after TBI regarding injury severity; preinjury psychiatric, socioeconomic, family functioning, and family psychiatric history status; and neuroimaging was analyzed. ODD symptomatology in the first year after TBI was related to preinjury family function, social class, and preinjury ODD symptomatology. Increased severity of TBI predicted ODD symptomatology 2 years after injury. Change (from before TBI) in ODD symptomatology at 6, 12, and 24 months after TBI was influenced by socioeconomic status. Only at 2 years after injury was severity of injury a predictor of change in ODD symptomatology. The influence of psychosocial factors appears greater than severity of injury in accounting for ODD symptomatology and change in such symptomatology in the first but not the second year after TBI in children and adolescents. This appears related to persistence of new ODD symptomatology after more serious TBI.     

Attention-deficit hyperactivity symptomatology after traumatic brain injury: a prospective study

OBJECTIVE: To study prospectively the course of attention-deficit hyperactivity (ADH) symptomatology in children and adolescents after traumatic brain injury (TBI). It was hypothesized that ADH symptomatology would be significantly related to severity of injury. METHOD: Subjects were children (n = 50) aged 6 to 14 years at the time they were hospitalized after TBI. The study used a prospective follow-up design. Assessments of preinjury psychiatric, behavioral, socioeconomic, family functioning, and family psychiatric history status were conducted. Severity of injury was assessed by standard clinical scales, and neuroimaging was analyzed. RESULTS: The main finding of this study was that change in ADH symptomatology in the first 2 years after TBI in children and adolescents was significantly related to severity of injury. Overall ADH symptomatology during the study was significantly related to a measure of family dysfunction when family psychiatric history, socioeconomic status, and severity of injury were controlled. CONCLUSION: The presence of a positive "dose-response" relationship between severity of injury and change in ADH symptoms, present from the 3-month assessment, was consistent with an effect directly related to brain damage.     

Posttraumatic stress symptomatology after childhood traumatic brain injury

The purpose of this study was to quantify and to identify predictors of posttraumatic stress disorder (PTSD) symptomatology after traumatic brain injury (TBI). Fifty children aged 6 to 14 years, hospitalized after TBI, were assessed soon after TBI regarding injury severity and preinjury psychiatric, socioeconomic, family functioning, and family psychiatric history status; neuroimaging was also analyzed. Psychiatric assessments were repeated 3, 6, 12, and 24 months after TBI. Only 2 of 46 (4%) subjects with at least one follow-up assessment developed PTSD. However, the frequency with which subjects experienced at least one PTSD symptom ranged from 68% in the first 3 months to 12% at 2 years in assessed children. The presence of an internalizing disorder at time of injury followed by greater injury severity were the most consistent predictors of PTSD symptomatology. It is apparent, therefore, that PTSD and subsyndromal posttraumatic stress disturbances occur despite neurogenic amnesia. These problems should be treated, particularly if symptoms persist beyond 3 months.     

Cognitive outcome in children and adolescents following severe traumatic brain injury: influence of psychosocial, psychiatric, and injury-related variables

Previous studies of childhood traumatic brain injury (TBI) have emphasized injury-related variables rather than psychiatric or psychosocial factors as correlates of cognitive outcomes. We addressed this concern by recruiting a consecutive series (N = 24) of children age 5 through 14 years who suffered a severe TBI, a matched group who sustained a mild TBI, and a second matched group who sustained an orthopedic injury. Standardized intellectual, memory, psychiatric, family functioning, family psychiatric history, neurological, and neuroimaging assessments were conducted at an average of 2 years following injury. Severe TBI, when compared to mild TBI and orthopedic injury, was associated with significant decrements in intellectual and memory function. A principal components analysis of independent variables that showed significant (p < .05) bivariate correlations with the outcome measures yielded a neuropsychiatric factor encompassing severity of TBI indices and postinjury psychiatric disorders and a psychosocial disadvantage factor. Both factors were independently and significantly related to intellectual and memory function outcome. Postinjury psychiatric disorders added significantly to severity indices and family functioning and family psychiatric history added significantly to socioeconomic status in explaining several specific cognitive outcomes. These results may help to define subgroups of children who will require more intensive services following their injuries.     

Understanding predictors of functional recovery and outcome 30 months following early childhood head injury.

Much is known about outcome following traumatic brain injury (TBI) in school-age children; however, recovery in early childhood is less well understood. Some argue that such injuries should lead to good outcome, because of the plasticity of the developing brain. Other purport that the young brain is vulnerable, with injury likely to result in a substantial impairment (H. G. Taylor & J. Alden, 1997). The aim of this study was to examine outcomes following TBI during early childhood, to plot recovery over the 30 months postinjury, and to identify predictors of outcome. The study compared 3 groups of children sustaining mild, moderate, and severe TBI, ages 2.0 to 6.11 years at injury, with healthy controls. Groups were comparable for preinjury adaptive and behavioral function, psychosocial characteristics, age, and gender. Results suggested a strong association between injury severity and outcomes across all domains. Further, 30-month outcome was predicted by injury severity, family factors, and preinjury levels of child function. In conclusion, children with more severe injuries and lower preinjury adaptive abilities, and whose families are coping poorly, are at greatest risk of long-term impairment in day-to-day skills, even several years postinjury.

A prospective study of short- and long-term outcomes after traumatic brain injury in children: Behavior and achievement.

Longitudinal behavior and achievement outcomes of traumatic brain injury (TBI) were investigated in 53 children with severe TBI, 56 children with moderate TBI, and 80 children with orthopedic injuries not involving brain insult. Measures of preinjury child and family status and of postinjury achievement skills were administered shortly after injury. Assessments were repeated 3 times across a mean follow-up interval of 4 years. Results from mixed model analysis revealed persisting sequelae of TBI. Recovery of math skills was observed in the severe TBI group but only for children from less stressed families. Social disadvantage in children with TBI predicted more adverse behavioral sequelae and less favorable changes in some outcome measures. The findings suggest that pediatric TBI has long-term effects on behavior and achievement but that postinjury progress is influenced by the family environment.

Influences on first-year recovery from traumatic brain injury in children.

This study examined recovery over the first year following traumatic brain injury (TBI) in children 6–12 years of age. Forty-two children with severe TBI and 52 with moderate TBI were compared to 58 children with orthopedic injuries. The children and their families were evaluated at a baseline assessment and at 6- and 12-month follow-ups. Findings documented cognitive, achievement, and behavioral sequelae of TBI, with only limited evidence for recovery over the first year postinjury. Outcomes were predicted by preinjury factors, TBI severity, and measures of the postinjury family environment. Some of the sequelae of severe TBI were more marked in the context of higher compared with lower levels of family burden or dysfunction. The findings confirm the need to consider environmental contributions to outcomes of TBI in children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does preinjury alcohol use or blood alcohol level influence cognitive functioning after traumatic brain injury?

Objective: To examine the relations among preinjury alcohol use patterns and admission blood alcohol level (BAL) and postinjury cognitive functioning among individuals with recent TBI. Design: Cohort survey with chart review and follow-up cognitive assessment. Setting: Acute inpatient rehabilitation program in a Level I trauma center. Participants: 124 consecutive initial admissions meeting inclusion criteria. Measures: Admission BAL, preinjury alcohol consumption, consequences, and symptoms of dependence, as well as initial injury severity and subsequent cognitive functioning. Results: Higher BAL at hospital admission was related to greater initial injury severity (lower Glasgow Coma Scale score). Preinjury alcohol consumption and admission BAL were not consistently related to any postinjury assessment of cognition. Conclusion: Alcohol use at the time of injury may exacerbate the initial severity of TBI. Cognitive functioning soon after injury does not appear to be related to any preinjury drinking behavior.

The relationship of parental warm responsiveness and negativity to emerging behavior problems following traumatic brain injury in young children.

Parenting behaviors play a critical role in the child's behavioral development, particularly for children with neurological deficits. This study examined the relationship of parental warm responsiveness and negativity to changes in behavior following traumatic brain injury (TBI) in young children relative to an age-matched cohort of children with orthopedic injuries (OI). It was hypothesized that responsive parenting would buffer the adverse effects of TBI on child behavior, whereas parental negativity would exacerbate these effects. Children, ages 3–7 years, hospitalized for TBI (n = 80) or OI (n = 113), were seen acutely and again 6 months later. Parent–child dyads were videotaped during free play. Parents completed behavior ratings (Child Behavior Checklist; T. M. Achenbach & L. A. Rescorla, 2001) at both visits, with baseline ratings reflecting preinjury behavior. Hypotheses were tested using multiple regression, with preinjury behavior ratings, race, income, child IQ, family functioning, and acute parental distress serving as covariates. Parental responsiveness and negativity had stronger associations with emerging externalizing behaviors and attention-deficit/hyperactivity disorder symptoms among children with severe TBI. Findings suggest that parenting quality may facilitate or impede behavioral recovery following early TBI. Interventions that increase positive parenting may partially ameliorate emerging behavior problems. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do neurocognitive ability and personality traits account for different aspects of psychosocial outcome after traumatic brain injury?

Objective: To examine the contributions of demographic, injury, cognitive, and personality characteristics to psychosocial outcome 8 years after traumatic brain injury (TBI). Design: Multiple regression analyses were used to estimate the variance explained by putative "predictors" of psychosocial outcome. Participants: Thirty-nine TBI survivors and 39 family member informants. On the basis of Glasgow Coma Scale scores and Accident Injury Severity (head) ratings, the patients' brain injuries ranged from mild to critical in severity. Main Outcome Measures: One self-report measure combined putative markers of social role engagement, such as marital status and earned income. Another, based on informant ratings using the Katz Adjustment Scale, was conceptualized as reflecting behavioral adjustment. Results: Whereas cognitive functioning explained significant unique variation in social role engagement, it did not account for variance in behavioral adjustment. Conversely, whereas 3 personality trait ratings explained significant incremental variance in behavioral stability, only 1 did the same with respect to social role engagement. Conclusions: Social role engagement and behavioral adjustment appear to represent 2 related but distinguishable aspects of TBI outcome that are associated with different patient characteristics.

Base Rates of Traumatic Brain Injury History in Adults Admitted to State Psychiatric Hospitals: A 3-Year Study.

Objectives: To determine the base rate of traumatic brain injury (TBI) in adults admitted to state psychiatric hospitals. Participants: A total of 3,133 psychiatric patients between the ages of 18 and 60 years old from 7 state facilities were screened for TBI and associated sequelae during a 3-year study period. Method: Comprehensive medical chart/documentation review and treating psychiatrist assessment. Results: A total of 524 (16.73%) had a documented history of TBI, 195 (6.22%) held a previous diagnosis of organic mental disorder at time of admission, 57 (1.82%) had clinical symptoms considered to be consistent with TBI sequelae, and 201 (6.42%) were diagnosed with dysfunction of thinking secondary to TBI. Conclusions: Findings support specific assessment for TBI in these populations, especially in light of previous studies suggesting that psychiatric patients with a history of TBI may require more specialized treatments.

Personality and functional outcome following traumatic brain injury.

Objective: To investigate pre- to postinjury personality change in relation to outcomes following traumatic brain injury (TBI). Design: Prospective analysis of personality ratings, depression, and outcome using multiple regression analyses. Participants: Cohort of 3 clinical trauma groups (mild TBI, moderate-severe TBI, orthopedic injury) and their significant others (SO). Outcome Measures: Independent Living Scale, Vocational Independence Scale, and Mayo-Portland Adaptability Inventory, 1-2 years postinjury. Predictor Variables: Posttraumatic amnesia (PTA); patient and SO NEO Personality Inventory-Revised ratings of preinjury personality taken at 1-2 months postinjury. Results: Personality function was normal for all groups (regardless of rating source) and stable over time. Neuroticism, and specifically depression, accounted for small proportions of variance in functional outcome, beyond PTA. Conclusions: There is little empirical evidence for significant personality disturbance or change up to 2 years post-TBI. Personality and depression contribute modestly to functional outcomes. Results support a distinction between "personality change" and behavior change following TBI. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The family environment as a moderator of psychosocial outcomes following traumatic brain injury in young children.

Objective: This study sought to determine whether the family environment moderates psychosocial outcomes after traumatic brain injury (TBI) in young children. Method: Participants were recruited prospectively from consecutive hospital admissions of 3- to 6-year-old children, and included 19 with severe TBI, 56 with complicated mild/moderate TBI, and 99 with orthopedic injuries (OI). They completed 4 assessments across the first 18 months postinjury. The initial assessment included measures of parenting style, family functioning, and the quality of the home. Children's behavioral adjustment, adaptive functioning, and social competence were assessed at each occasion. Mixed model analyses examined the relationship of the family environment to psychosocial outcomes across time. Results: The OI and TBI groups differed significantly in social competence, but the family environment did not moderate the group difference, which was of medium magnitude. In contrast, group differences in behavioral adjustment became more pronounced across time at high levels of authoritarian and permissive parenting; among children with severe TBI, however, even those with low levels of permissive parenting showed increases in behavioral problems. For adaptive functioning, better home environments provided some protection following TBI, but not over time for the severe TBI group. These 3-way interactions of group, family environment, and time postinjury were all of medium magnitude. Conclusion: The findings indicate that the family environment moderates the psychosocial outcomes of TBI in young children, but the moderating influence may wane with time among children with severe TBI.

Interpersonal Stressors and Resources as Predictors of Parental Adaptation Following Pediatric Traumatic Injury.

The authors examined the relationship of preinjury interpersonal resources and stressors to parental adaptation following pediatric traumatic brain injury (TBI) and orthopedic injury. Parents of children with severe TBI (n = 53), moderate TBI (n = 56), and orthopedic injuries (n = 80) were assessed soon after injury, 6 and 12 months after the initial evaluation, and at an extended follow-up with a mean of 4 years postinjury. General linear model analyses provide support for both main and moderating effects of stressors and resources on parental adjustment. Support from friends and spouse was associated with less psychological distress, whereas family and spouse stressors were associated with greater distress. The results also reveal a marked decline in injury-related stress over follow-up for families in the severe TBI group who reported a combination of high stressors and high resources. The decline suggests that interpersonal resources attenuated long-term family burden because of severe TBI. The findings are discussed in terms of their implications for intervention following TBI.

Personality Factors and Injury Severity in the Prediction of Early and Late Traumatic Brain Injury Outcomes.

Objective: To identify personality features predicting early and late outcome after traumatic brain injury (TBI). Design: Multiple regression analyses of data from an inception cohort. Participants: Sixty-nine persons with moderate to severe TBI and significant others (SOs). Outcome Measures: Rasch measure of supervision, independent living, and work (Participation and Independence Measure) at hospital discharge and at 1-year follow-up. Predictor Variables: Duration of posttraumatic amnesia (PTA) and NEO Personality Inventory-Revised completed by participants and SOs to describe participant's preinjury personality. Results: Overall personality variables were within normal limits. Only self-reported Neuroticism, specifically Depression, added significantly to PTA in predicting early outcome. Conclusions: Although self-reported depression negatively affects TBI outcome, other personality features reported by people with TBI and SOs during early recovery are normal and do not affect outcome.

A prospective study of short- and long-term neuropsychological outcomes after traumatic brain injury in children.

Longitudinal neuropsychological outcomes of traumatic brain injury (TBI) were investigated in 53 children with severe TBI, 56 children with moderate TBI, and 80 children with orthopedic injuries only. Neuropsychological functioning was assessed at baseline, at 6- and 12-month follow-ups, and at an extended follow-up (a mean of 4 years postinjury). Mixed model analyses revealed persistent neuropsychological sequelae of TBI that generally did not vary as a function of time postinjury. Some recovery occurred during the first year postinjury, but recovery reached a plateau after that time, and deficits were still apparent at the extended follow-up. Further recovery was uncommon after the first year postinjury. Family factors did not moderate neuropsychological outcomes, despite their demonstrated influence on behavior and academic achievement after childhood TBI.

Psychosocial factors limit outcomes after trauma

BACKGROUND: Psychological morbidity compromises return to work after trauma. We demonstrate this relationship and present methods to identify risks for significant psychological morbidity. METHODS: Thirty-five adults were evaluated prospectively for return to functional employment after injury using demographic data, validated psychological and health measures, and the Michigan Critical Events Perception Scale. Evaluation was conducted at admission and at 1 and 5 months after injury. RESULTS: Poor return to work at 5 months was attributable to physical disability (p < 0.05) and psychological disturbance (p < 0.05) in a regression model that controlled for preinjury employment and psychopathologic factors as well as injury severity. A high score on the Impact of Events Scale administered during acute admission predicted development of acute stress disorder at 1 month (p < 0.01, odds ratio (OR) = 9.4) and posttraumatic stress disorder at 5 months (p < 0.05, OR = 6.7). Peritraumatic dissociation on the Michigan Critical Events Perception Scale was predictive for development of acute stress disorder (p < 0.05, OR = 5.8) at 1 month and posttraumatic stress disorder (p < 0.05, OR = 7.5) at 5 months. CONCLUSION: Psychological morbidity after injury compromises return to work independent of preinjury employment and psychopathologic condition, Injury Severity Score, or ambulation. A high Impact of Events Scale score or peritraumatic dissociation at admission predicts this morbidity.     

Predicting premorbid neuropsychological functioning following pediatric traumatic brain injury

This study examined the prediction of premorbid neuropsychological functioning using data from an ongoing prospective study of traumatic brain injuries (TBI) in children ages 6 to 12 years. Prediction equations were derived based on 80 children with orthopedic injuries (OI), who served as a comparison group for the children with TBI. Collectively, parent ratings of premorbid school performance, maternal ethnicity, family socioeconomic status, and children's word recognition skill predicted from 13% to 45% of the variance in three measures of neuropsychological functioning. The regression equations were used to compute predicted scores among 109 children with TBI. Actual scores fell significantly below predicted scores among children with TBI, and the magnitude of the deficits was correlated with injury severity. Premorbid neuropsychological functioning can be predicted in children with TBI, but with less precision than would be desirable for clinical purposes.     

Clinically significant behavior problems during the initial 18 months following early childhood traumatic brain injury.

Objective: This study looked at the emergence of clinically significant problems in behavior, executive function skills, and social competence during the initial 18 months following traumatic brain injury (TBI) in young children relative to a cohort of children with orthopedic injuries (OI) and the environmental factors that predict difficulties postinjury. Participants: Children, ages 3–7 years, hospitalized for severe TBI, moderate TBI, or OI were seen shortly after their injury (M = 40 days) and again 6 months, 12 months, and 18 months postinjury. Design: Behavioral parent self-reports, demographic data, family functioning reports, and home environment reports were collected at injury baseline and each time point postinjury. Results: Results suggest that, compared with the OI group, the severe TBI group developed significantly more externalizing behavior problems and executive function problems following injury that persisted through the 18-month follow-up. Minimal social competence difficulties appeared at the 18-month follow-up, suggesting a possible pattern of emerging deficits rather than a recovery over time. Conclusions: Predictors of the emergence of clinically significant problems included permissive parenting, family dysfunction, and low socioeconomic status. The findings are similar to those found in school-age children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
