Group psychotherapy for persons with traumatic brain injury: management of frustration and substance abuse

Residual emotional and behavioral difficulties in individuals who have sustained a traumatic brain injury (TBI) have been well documented in the literature. The issues are complex, interdependent, and often include substance abuse, depression, anxiety, chronic suicidal or homicidal ideation, poor impulse control, and significant degrees of frustration and anger. Often, preexisting psychological conditions and poor coping strategies are exacerbated by the trauma. Emotional and behavioral difficulties can interfere with the neurorehabilitation process at all levels. In acute rehabilitation, these issues have traditionally been addressed on an individual basis. However, in postacute settings, an interpersonal group format can be effectively implemented. The majority of individuals with TBI have minimal funding for long-term cognitive and behavioral remediation; often the only avenue available is support groups. This article will describe group psychotherapy models used with individuals with acute or postacute TBI within a comprehensive rehabilitation center. Interdisciplinary treatment of frustration and substance abuse and a continuum of care will be emphasized. Education, social support, skills development, interpersonal process, and cognitive-behavioral approaches will also be discussed. The psychotherapy groups focus on treatment of substance abuse and frustration management through education, social support, and development of interpersonal skills. Practical considerations of running such groups are presented.     

Screening for alcoholism among persons with recent traumatic brain injury.

This study examined the clinical utility of various brief screening procedures for identifying persons with a prior history of alcoholism among patients with recent traumatic brain injury (TBI). Participants were 50 patients assessed for various aspects of alcohol use and abuse during their acute rehabilitation hospitalization. Predictive indicators were tested against the Michigan Alcoholism Screening Test (MAST) as the criterion measure. Results indicated the 13-item Short Michigan Alcoholism Screening test is a good proxy for the longer MAST in this population. The two screening questions by M. Cyr and S. Wartman (1988) also have some limited utility. Practical implications of the results are discussed with a view toward adopting universal screening for alcoholism among persons with recent TBI.

The relationship between sexual abuse and mild traumatic brain injury

It remains unclear why some individuals with mild traumatic brain injury (MTBI) complain of cognitive deficits many months after the injury. Given neuropathological changes associated with prolonged stress, such as occurs with repeated sexual abuse (SA), it seems possible that individuals who experienced SA might be predisposed to greater deficits after MTBI. Four groups of subjects were administered measures of cognitive and emotional functioning. These groups were those with MTBI (n = 10), those with a history of SA (n = 10), those with both MTBI and SA (n = 10), and normal control (NC) subjects (n = 10). Compared to the NC subjects, those with MTBI demonstrated deficits in working memory, those with SA demonstrated deficits in executive functioning, and those with both MTBI and SA demonstrated the greatest number of deficits which were in working memory, executive functioning and memory. Tests of anxiety, depression and post-traumatic stress disorder, while demonstrating significant symptoms in all clinical groups, did not correlate with the neuropsychological tests that differentiated the groups.     

Neuropsychological outcomes of traumatic brain injury and substance abuse in a New Zealand prison population

Fifty subjects with a history of traumatic brain injury (TBI) and/or substance use, completed neuropsychological measures of short and long term verbal and visual memory, information processing, motor speed and co-ordination, executive functioning, and malingering. All subjects performed below norms on tests of verbal memory and verbal abstract thinking, but overall no differences were found due to either severity of TBI or level of substance use. Maori subjects obtained the lowest scores on tests of verbal ability, but also reported higher rates of TBI and substance use, which is presumed to account for this result. In conclusion, prison populations seem to have disproportionately high rates of TBI, recurrent TBI, and substance use, compared to the general population. Further, there are a group of individuals who have experienced both TBI and substance abuse, with associated impairments in verbal memory and learning, abstract thinking, and who report problems with general memory and socialization. These difficulties may affect functioning both in prison and following release.     

The effectiveness of computer-assisted cognitive rehabilitation for persons with traumatic brain injury

Electroencephalographic (EEG) findings in syncope are reviewed. There are four major categories of syncope: neurally mediated (neurocardiogenic), neurologic, decreased cardiac output, and orthostatic hypotension. However, regardless of cause, whether the syncope is due to a vasovagal effect, a cardiac arrhythmia, an epileptic seizure, or hypotension, EEG findings are similar and reflect cerebral hypoperfusion. Initially there may be a slowing of background rhythms. This is followed by high amplitude delta activity, maximal anteriorly. If the hypoperfusion persists there is subsequent flattening of the EEG. The EEG returns to normal in the reverse sequence. In cases with severe and prolonged ischemia, convulsive syncope may occur at the time of the EEG flattening. Although not an epileptic phenomena, clinically this is often mistaken for epilepsy. Conversely, epileptic disorders, such as the ictal bradycardia syndrome, may occasionally mimic syncope. Therefore, in patients in whom EEGs are performed for the evaluation of an episode of loss of consciousness, simultaneous ECG should be used.     

Gender differences in homeless persons with schizophrenia and substance abuse

The purpose of this study was to test the generalizability of previous research on gender differences between men and women with co-occurring schizophrenia and substance abuse. One hundred eight patients with schizophrenia or schizo-affective disorder involved in a study of treatment for homeless persons were interviewed for information regarding substance use, social functioning and support, comorbid disorders, victimization, medical illness, and legal troubles. We found that women had more children and were more socially connected than men. Women also had higher rates of sexual and physical victimization, comorbid anxiety and depression, and medical illness than men. We conclude that homeless women with dual disorders, like women with substance use disorders in the general population, have distinct characteristics, vulnerabilities, and treatment needs compared with men. In addition to comprehensive treatment of psychiatric and substance use disorders, gender-specific services should be developed, including prevention and treatment of victimization and related problems as well as help with accessing medical services.     

Two abbreviated versions of the Wechsler Adult Intelligence Scale-III: Validation among persons with traumatic brain injury.

Objective: To examine the clinical value of two 7-subtest versions of the Wechsler Adult Intelligence Scale-III (WAIS-111): one using Block Design (WAIS-III/BD7) and another using Matrix Reasoning (WAIS-III/MR7) among persons with traumatic brain injury (TBI). Study Design: Actual obtained scores from the full WAIS-111 were compared with scores that would have been obtained using each of the two abbreviated versions. Participants: One hundred eighteen persons with TBI tested consecutively in an academic medical center outpatient neuropsychology laboratory. Results: For the WAIS-IIVBD7, corrected validity coefficients were .97 (Verbal IQ [VIQI), .94 (Performance IQ [PIQ]), and .97 (Full Scale IQ [FSIQJ); 92%, 70%, and 92% of scores fell within 5 points of full version scores for VIQ, PIQ, and FSIQ, respectively. WAIS-III/MR7 corrected validity coefficients were .97 (VIQ), .95 (PIQ), and .97 (FSIQ); 92%, 76%, and 92% of short-form scores were within 5 points of actual scores for VIQ, PIQ, and FSIQ, respectively. Conclusions: Both abbreviated versions demonstrated acceptable psychometric characteristics, but the matrix reasoning version may be more advantageous in assessing persons with TBI because it can be used with persons who have TBI-related motor skills impairment.

Agreement between persons with traumatic brain injury and their relatives regarding psychosocial outcome using the Community Integration Questionnaire

Cerebral cavernous angiomas are congenital malformations usually presenting with symptomatic hemorrhages or seizures. The advent of MRI has allowed to detect asymptomatic, "cryptic" brain cavernomas. They can occur in a sporadic, isolated form and in a familial form characterized by multiple lesions. Surgical treatment is recommended by most authors in symptomatic cases when the lesion is isolated and readily accessible. Treatment is more controversial when the vascular malformation is located in critical brain region. On the other hand the increased risk of rebleeding after a prior hemorrhage and the decreased effectiveness of lesionectomy in patients with a long seizure history could lead to perform an early surgical excision also for cavernous angiomas located in those areas. We report three cases of symptomatic cerebral cavernomas located in critical areas, in children. In all cases the surgical removal of the lesions was successfully performed. The two cases presented with seizures are seizure-free in spite of the interruption of the antiepileptic therapy. The patient presented with neurological deficit due to intraparenchymal hemorrhage progressively recovered his motor function. Our experience seems to confirm the value of surgical removal regardless of where the cavernoma is located.     

Alcohol abuse and traumatic brain injury: effect on event-related potentials

OBJECTIVE: To examine the individual and combined impact that traumatic brain injury (TBI) and heavy social use of alcohol have on electrophysiologic correlates of working memory and evaluation of task-relevant information. DESIGN: Case-control study. SETTING: University hospital brain injury rehabilitation unit. PARTICIPANTS: Forty male volunteers divided into four groups on the basis of their history of TBI and alcohol intake. Subjects with TBI had experienced a severe closed head injury at least 1 year before testing. MAIN OUTCOME MEASURE: Event-related potentials (ERPs) and neuropsychometric tests. RESULTS: Groups showed no significant differences in average age or neuropsychological tests. TBI groups did not differ in time postinjury or on severity measures. Alcohol use measures were significantly greater in the two alcohol groups. N200 latency and P300 amplitude were impaired in heavy social drinkers and in nondrinking subjects with TBI relative to controls, but were significantly impaired in subjects with TBI who were also heavy social drinkers. CONCLUSION: The results indicate that although alcohol use and TBI independently produce mile alterations in some aspects of late ERP components, the ERP changes are significantly greater when alcohol use and TBI are combined. This study provides evidence that heavy social drinking after TBI has a measurable impact on electrophysiologic correlates of cognition.     

The reliability and validity of the Community Integration Measure in persons with traumatic brain injury.

Objective: To investigate the psychometric properties of the Community Integration Measure (CIM), a scale that assesses self-perceived quality of community integration, among persons with traumatic brain injury (TBI). Method: Persons (N = 279) with TBI completed the CIM, as well as other measures of community integration and quality of life, and were followed up to 15 years postinjury. Results: The CIM was found to be a reliable instrument with adequate internal consistency. Validity was demonstrated in its relationship to other measures of community integration and life satisfaction. Utility was evident in its prediction of perceived social support. Conclusion: Results suggest that the CIM is an adequate measure of community integration for persons with histories of TBI of up to 15 years.

Religion and spirituality in rehabilitation outcomes among individuals with traumatic brain injury.

Objective: The long-term consequences of traumatic brain injury affect millions of Americans, many of whom report using religion and spirituality to cope. Little research, however, has investigated how various elements of the religious and spiritual belief systems affect rehabilitation outcomes. The present study sought to assess the use of specifically defined elements of religion and spirituality as psychosocial resources in a sample of traumatically brain injured adults. Participants: The sample included 88 adults with brain injury from 1 to 20 years post injury and their knowledgeable significant others (SOs). The majority of the participants with brain injury were male (76%), African American (75%) and Christian (76%). Measures: Participants subjectively reported on their religious/spiritual beliefs and psychosocial resources as well as their current physical and psychological status. Significant others reported objective rehabilitation outcomes. Analyses: Hierarchical multiple regression analyses were used to determine the proportion of variance in outcomes accounted for by demographic, injury related, psychosocial and religious/spiritual variables. Results: The results indicate that religious well-being (a sense of connection to a higher power) was a unique predictor for life satisfaction, distress and functional ability whereas public religious practice and existential well-being were not. Conclusions: The findings of this project indicate that specific facets of religious and spiritual belief systems do play direct and unique roles in predicting rehabilitation outcomes whereas religious activity does not. Notably, a self-reported individual connection to a higher power was an extremely robust predictor of both subjective and objective outcome.

Self-report and observer measures of substance abuse among homeless mentally ill persons in the cross-section and over time

The comparability of self-report and observer measures of substance abuse among 118 homeless mentally ill persons was assessed using cross-sectional and longitudinal measures. Possible correlates of nondisclosure were identified from demographic variables and clinical indicators. Lifetime abuse reported at baseline was a sensitive predictor of subsequent abuse behavior in the project, but cross-sectional measures based only on self-report or observer ratings failed to identify many abusers. A total of 17% of the subjects never disclosed abuse that was observed during the project. The level of substance abuse is likely to be severely underestimated among homeless mentally ill persons when only one self-report measure is used at just one point in time. This problem can, however, largely be-overcome by incorporating information from observers and from multiple follow-ups or by focusing on lifetime rather than current abuse. We also conclude that underreporting may bias estimates of some correlates of substance abuse.     

The efficacy of the generation effect in improving new learning in persons with traumatic brain injury.

Objective: To evaluate the usefulness of the generation effect in improving learning and memory abilities in neurologically impaired individuals. The generation effect is the observation that items self-generated by participants are better remembered than items provided by the examiner. Although this effect has shown to be relatively robust in healthy adults, few studies have examined the usefulness of the generation effect in neurological populations. Participants: 18 individuals with moderate-severe traumatic brain injury (TBI) and 18 healthy adults. Main Outcome Measure: The measure was the generation effect protocol. Results: Results indicated recall and recognition of generated information was significantly higher than that of provided information across testing conditions. However, healthy adults showed greater benefit from the generation effect than did individuals with TBI. As expected, recall and recognition performance diminished over time (i.e., immediate recall, 30 min, 1 week) however, rates of forgetting did not differ between groups. Conclusion: Self-generation significantly improved verbal learning and memory in individuals with TBI. The results of self-generation in improving learning suggest that applying that technique may be beneficial in the cognitive rehabilitation of persons with TBI.

Towards a more integrated approach to job placement and retention for persons with traumatic brain injury and premorbid disadvantages

Health is part of our own personal well-being, as well as that of the community and of our nation: clinician-investigators lead us forward in new medical developments, and may even be of assistance in developing innovative programs of cost control and outcome analysis. Canada now devotes close to 10% of its gross national product to health expenditures, second only to the United States, and yet there is still the widespread perception within this country that "there is not enough." The issues are how to do more with less, and how to recruit more clinician-investigators from the diminishing pool of potential recruitees. Academic medicine, with its research focus, is well-suited to bring together newer perspectives of education and health, and these clinician-investigators may improve major areas of our health care partnership.     

The validity of the Katz Adjustment Scale among people with traumatic brain injury.

Deficits in self- and social awareness can impair adjustment following traumatic brain injury (TBI) and draw into question the accuracy of self-report measures of adjustment. This study evaluates the validity of Katz Adjustment Scale (KAS) factor components identified by R. J. Fabiano and D. A. Goran (1992). The KAS is an observer rating scale often used to assess the social adjustment of people with traumatic brain injury. The responses of 105 individuals with TBI to the Symptom Checklist 90—Revised (SCL-90–R; L. R. Derogatis, 1983), a self-report measure of distress, were correlated with observer ratings on the KAS. Results support the use of observer ratings and self-report to assess adjustment and social behavior following TBI. Each contributes valuable information that can guide treatment and enhance adaptive functioning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Substance use and abuse among patients with comorbid dysthymia and substance disorder

This study determines the substance use and abuse patterns among patients with comorbid substance-related disorder (SRD) and dysthymia in SRD-dysthymia as compared with patients with SRD only. Differences in use and abuse patterns could be useful for (a) understanding motivations for use, such as self-treatment, and (b) assisting clinicians to identify cases of dysthymia among SRD patients. Retrospective and current data were obtained regarding history of substance use and current SRD diagnoses. Two university medical centers with alcohol-drug programs located within departments of psychiatry were the settings. A total of 642 patients was assessed. of whom 39 had SRD-dysthymia and 308 had SRD only. Data on past usc were collected by a research associate using a questionnaire. Current SRD and dysthymia diagnoses were made by psychiatrists specializing in addiction. The patients with SRD-dysthymia and SRD only did not differ with regard to use of alcohol, tobacco, and benzodiazepines. The patients with SRD-dysthymia started caffeine use at an earlier age, had shorter "use careers" of cocaine, amphetamines, and opiates, and had fewer days of cocaine and cannabis use in the last year. They also had a lower rate of cannabis abuse/dependence. This study indicated that patients with dysthymia and SRD have exposure to most substances of abuse that is comparable to patients with SRD only. However, they selectively use certain substances less often than patients with SRD only. Early use of caffeine may reflect self-treatment for depressive symptoms among patients with SRD-dysthymia.     

Predicting substance abuse among youth with, or at high risk for, HIV.

This article describes data from 4,111 males and 4,085 females participating in 10 HIV/AIDS service demonstration projects. The sample was diverse in age, gender, ethnicity, HIV status, and risk for HIV transmission. Logistic regression was used to determine the attributes that best predict substance abuse. Males who were younger, HIV positive; homeless; involved in the criminal justice system; had a sexually transmitted disease (STD); engaged in survival sex; and participated in risky sex with men, women, and drug injectors were most likely to have a substance abuse history. For females, the same predictors were significant, with the exception of having an STD. Odds ratios as high as 6 to 1 were associated with the predictors. Information about sexual and other risk factors also was highly predictive of substance abuse issues among youth. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality disturbances associated with traumatic brain injury.

Personality disturbances associated with traumatic brain injury are reviewed. The varied structural pathology of the brain in this patient group makes it difficult to specify how different brain lesions may result in specific emotional and motivational disturbances. However, an attempt to clarify terms and review empirical findings is made. Longitudinal prospective studies that utilize appropriate control groups are needed. Future research may especially benefit by considering the long-term effects of early agitation following traumatic brain injury as well as the problem of aspontaneity and impairment of self-awareness.
