Effectiveness of a group anger management programme after severe traumatic brain injury

Improving emotion regulation ability after brain injury: A systematic review of targeted interventions

Emotion dysregulation is a common sequela after a brain injury, and it can have serious negative consequences for individuals, families, and the community. A systematic review of the literature was conducted to identify and evaluate interventions designed to improve emotion regulation ability in adults with acquired brain injury. Studies were identified on ProQuest, PsycInfo, ScienceDirect, Scopus, and Web of Science; last searched on 3 August 2023. A review protocol was prospectively registered on PROSPERO (CRD42020218175). Risk of bias was assessed using the Cochrane Risk-of-Bias tool (version 2). Sixteen studies were included in the review comprising one case series, five pilot studies, four pre-post studies, and six RCTs. There was a total of 652 participants across studies. Fourteen of the sixteen studies reported statistically significant improvements in at least one emotional functioning variable. Ten studies reported medium-large effect sizes. Limitations included inconsistency in the measurement, reporting of intervention outcomes and processes. Future directions are discussed.

Evidence-Based Review of Randomized Controlled Trials of Interventions for the Management of Behavioral Issues in Individuals With Moderate to Severe Traumatic Brain Injury

OBJECTIVE

To present an evidence-based review of randomized controlled trials (RCTs) evaluating interventions for the management of behavioral issues post moderate to severe traumatic brain injury (MSTBI), as part of an extensive database that has been conceptualized as a living systematic review.

METHODS

Systematic searches were conducted in MEDLINE, PubMed, Scopus, CINAHL, EMBASE and PsycINFO, up to and including December 2022, for articles published in the English language, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The quality of RCT was assessed using the Physiotherapy Evidence Database (PEDro) scale, and level of evidence was assigned using a modified Sackett scale.

RESULTS

Forty-six RCTs examining interventions and outcome measures related to behavioral issues post-MSTBI were included. These studies collectively enrolled 3,267 participants. The majority of RCTs were conducted in the United States (n = 27; 58.7%) and 28 (60.9%) were conducted after 2010. Of these, 27 RCTs examined non-pharmacological interventions and 19 examined pharmacological interventions. Effective pharmacological treatments included amantadine and dexmedetomidine. Effective non-pharmacological interventions included sensory stimulation in the acute phase, anger self-management programs, peer mentoring, problem-solving, and emotional regulation. Psychotherapy showed conflicting evidence.

CONCLUSION

This evidence-based review provides a comprehensive overview of the research landscape of RCTs addressing behavior post-MSTBI. The findings from these RCTs may be valuable for health care professionals, researchers, and policymakers involved in the field of TBI and behavior.

Evaluating social rehabilitation of aggression for persons with Acquired Brain Injury: a systematic review

PURPOSE

Social rehabilitation of aggression following an Acquired Brain Injury (ABI) is critically important for persons with ABI due to increased vulnerability of criminal behaviour related to post-injury changes in functioning. This review presents findings from studies that evaluated aggression interventions in both community and forensic populations of people with ABI.

METHODS

We searched PsycINFO, EMBASE, SocINDEX, CINAHL and Medline databases for studies published between 1st January 2000 and 15th October 2023.

RESULTS

There were 15 studies (14 community-based, one forensic) that met inclusion criteria. Pharmacological management (6) was largely ineffective and anger management interventions (6) presented with inconsistent effectiveness. Emotion regulation (1) may be effective for externalised aggression. Both mindfulness and transcranial direct current stimulation (1) were effective, and the results of a forensic peer group approach (1) were not tested for statistical significance. There was variability in the measurement of aggression, injury severity, and cognitive impairment.

CONCLUSIONS

Whilst community interventions for aggression in persons with ABI are prevalent, findings for effectiveness have been mixed and there is a paucity of evaluated interventions in forensic samples. Further research is needed to unravel the complex interplay of factors contributing to aggression and develop effective social rehabilitation for persons with ABI.

Disinhibited and angry: Investigating the relationship between social disinhibition and the components of aggression following severe TBI

Social disinhibition and aggression share many similarities. But unlike with aggression, research evidence about social disinhibition following severe traumatic brain injury (TBI) is limited and treatments are missing. Establishing the association between aggression and social disinhibition would facilitate a better conceptualization of these disorders. This study aimed to determine the relationship between social disinhibition and aggression following severe TBI.In this case-control study, 25 individuals with severe TBI and 25 control participants completed the Buss-Perry Aggression Questionnaire (BPAQ), Frontal Systems Behaviour Scale (FrSBe), and Social Disinhibition Interview (SDI).Hierarchical multiple regression analyses revealed that, when controlling for covariates, the inclusion of BPAQ Anger in the model led to a 13% increase in proportion of explained variance of social disinhibition (Adjusted R2 increased from .243 to .363, p < .005). BPAQ Anger was not a significant predictor of SDI scores. Similarly, BPAQ Physical aggression scores did not contribute to the prediction of FrSBe Disinhibition or SDI scores.In conclusion, higher levels of self-reported anger (but no other components of aggression) are associated with higher levels of self-reported social disinhibition. While these findings have potential implications for the treatment of social disinhibition, further research into the possible relationship with aggression should be conducted.

Improving communication access in psychoeducational interventions for people with complex communication needs: a scoping review and stakeholder consultation

PURPOSE

Psychoeducational interventions are commonly used to improve mental health among the general population; however, their application among people with complex communication needs is under explored. This scoping review aims to identify the psychoeducational interventions utilised with people with complex communication needs, any adaptations to improve communication access, and outcomes for this population.

MATERIALS AND METHODS

The scoping review was conducted using the Arksey and O'Malley guidelines and included stakeholder consultations. A systematic search of the literature was conducted. Stakeholder consultations were conducted via semi-structured interviews with informants from three populations: people with complex communication needs, everyday communication partners and mental health workers.

RESULTS

The search yielded 2112 articles. Twenty-four articles were retained for data extraction. Numerical analysis provided an overview of the existing literature. Thematic analysis highlighted the range of communication access strategies applied within psychoeducational interventions. Common aims and outcomes of interventions occurred across three interrelated themes: education, symptom reduction, and improved coping and wellbeing. Stakeholder consultations enabled contextualisation of literature.

CONCLUSIONS

People with complex communication needs may benefit from psychoeducational interventions when effective, personalised communication access strategies are employed. Future research should include lived-experience perspectives to ensure the relevance of communication access strategies in mental health support.Implications for rehabilitationThis scoping review adds to the evidence base supporting equitable access to mental health support for people with complex communication needs.A range of specific strategies are presented for mental health workers to consider when working with people with complex communication needs.Positive behaviour support (PBS) practitioners must be equipped to address the psychoeducational and mental health support requirements of people with complex communication needs.

"Talk and Chalk": An emotion regulation intervention for anger after acquired brain injury

Uncontrollable anger is a debilitating consequence of acquired brain injury (ABI). This proof-of-concept study investigated the preliminary efficacy of an emotion regulation intervention for managing post-ABI anger. A secondary objective was to determine which participant characteristics were related to intervention gains. With a pre-post intervention design and three-month follow-up, there were five individually administered meetings on Zoom, over a four-month period. 24 adults who had sustained an ABI were enrolled. Participants were mostly males, from 24 to 85 years old. A series of one-way repeated-measures ANOVAs were conducted to determine the intervention's efficacy, and Spearman's rho bivariate correlations for the association between participant characteristics and intervention gains. Significant differences were observed in external anger from baseline to post-treatment; there were no further changes from post-treatment to follow-up. Of the participant characteristics, only readiness to change and anxiety were correlated. The proposed intervention presents a brief, feasible, and preliminary efficacious alternative for regulating post-ABI anger. Intervention gains are associated with readiness to change and anxiety, which has important implications for clinical delivery.

Predictors of Treatment Response to a Psychoeducational Intervention for Anger in Chronic Moderate-Severe Traumatic Brain Injury

OBJECTIVE

The investigators examined predictors of treatment response to anger self-management training (ASMT) among patients with chronic moderate-severe traumatic brain injury (TBI).

METHODS

A multicenter randomized clinical trial comprising 90 participants with moderate-severe TBI was conducted. Fifty-four participants who were randomly assigned to receive active treatment and provided complete data were included in the current secondary analysis. Model averaging was used to examine the relative importance and significance of pretreatment variables for predicting change during treatment. Dependent variables were pre- to posttreatment changes in trait anger (TA) and anger expression-out (AX-O) subscale scores of the State-Trait Anger Expression Inventory-Revised. Predictors included demographic, injury-related, and neuropsychological variables, including both objective and self-reported measures of executive function, as well as readiness to change and participation of a significant other in treatment.

RESULTS

Change in both dependent variables was predicted by higher baseline anger. Greater change in TA was additionally predicted by White race, higher education, shorter posttraumatic amnesia, and worse self-reported (but not objectively measured) executive dysfunction; the latter predictor may have indicated better self-awareness. Greater change in AX-O was additionally predicted by better episodic memory and, paradoxically, lower readiness to change.

CONCLUSIONS

Further research should focus on adapting psychoeducational anger treatments to better serve the diverse populations affected by moderate-severe TBI. These findings suggest that providing memory aids to support the use of learned strategies after treatment cessation would be beneficial. Further research should also examine the construct of readiness to change and specific aspects of executive function that may affect treatment response in psychoeducational treatments. These findings were derived from only one model of anger intervention, and the relevance to other treatment approaches cannot be assumed.

An intervention to improve coping strategies in adult male prisoners with a history of traumatic brain injury: A pilot randomised clinical trial

OBJECTIVE

To determine whether a psychological intervention improves coping, post-concussion symptoms and decreases in-prison infractions in adult males with a history of traumatic brain injury.

DESIGN

A single centre, randomised, wait-list, pilot study.

SETTING

A high security prison in New Zealand.

SUBJECTS

Fifty-five adult male participants who had experienced at least one traumatic brain injury in their lifetime (mean age 37.29 +/-9.81 years).

INTERVENTION

A manualised ten session, in-person, group based combined Cognitive Behavioural Therapy /Mindfulness Based Stress Reduction intervention versus wait list control.

MAIN MEASURES

The Negative Affect Repair Questionnaire and Rivermead Post-concussion Symptom Questionnaire were completed at baseline, post-intervention (five weeks) and at 12 week follow up. In-prison misconduct charges and negative file notes were reviewed for the previous five weeks at each assessment time point.

RESULTS

There was an improvement in the use of calming and distraction strategies in the intervention group from baseline (x̄ = 17.38, SD = 3.57) to post-intervention (x̄ = 18.67, SD = 3.84) and 12-week follow up (x̄ = 18.13, SD = 2.63). Participants in the intervention group had significantly higher negative affect repair on the calming and distractive strategies subscale following completion of the intervention, compared to wait-list controls (F = 4.69, P = 0.04) with a moderate effect size (η_p² = 0.11). Improvements in use of calming and distractive strategies was not sustained at the twelve-week follow-up (F = 0.87, P = 0.36). There was no-significant improvement on other negative affect subscales or for post-concussion symptoms or decrease in-prison infractions.

CONCLUSION

A manualised psychological intervention may have the potential to facilitate the development of positive coping strategies in prisoners with a history of traumatic brain injury.

Psychotherapy and Art Therapy: A pilot study of group treatment for patients with traumatic brain injury

Here we investigated the efficacy of group Psychotherapy and Art Therapy in rebuilding self-identity after traumatic brain injury (TBI), assessing their effects on psychological aspects in twelve patients with severe TBI. Overall, the results show an increased ability to adapt to the experiences of life as well as a higher level of awareness, social functioning and emotional autoregulation. Furthermore, patients exhibited a reduction in depressive symptoms and in the perception of physical problems. Results highlight the importance of treatments focusing on the patients' emotional needs, in addition to the classic rehabilitation (i.e. physiotherapy, cognitive therapy).

Cognitive behavioural therapy for aggression among individuals with moderate to severe acquired brain injury: a systematic review and meta-analysis

BACKGROUND

Aggression is common after an acquired brain injury (ABI). Cognitive behavioural therapy (CBT) is a form of psychotherapy, in which therapists help patients to identify their maladaptive behaviours.

OBJECTIVE

The objective of this systematic review and meta-analysis was to evaluate the effectiveness of CBT interventions in treating aggression in an ABI population.

METHODS

A systematic literature search was conducted using: PubMed/MEDLINE, CINAHL, EMBASE and PsycINFO from database inception to August 2016. English articles were included if: at least 50% of the study sample had a moderate to severe ABI, there were at least three adult human participants, and use of a CBT intervention for the treatment of aggression.

RESULTS

Seven articles met inclusion criteria: one RCT, an RCT crossover and five pre-post trials. Of these, four articles were included in a pre-post meta-analysis for treatment efficacy on subscales of the State Trait Anger Expression Inventory (STAXI) and STAXI-2 outcome measures. The meta-analysis found CBT was effective in moderating the external behaviours of aggression, but not internal anger.

CONCLUSION

The differences in outcomes may be related to the differential management of anger expression and anger suppression. CBT shows promise, but further studies with comparator groups are needed before conclusions about its efficacy can be made.

Reductions in Alexithymia and Emotion Dysregulation After Training Emotional Self-Awareness Following Traumatic Brain Injury: A Phase I Trial

OBJECTIVES

To examine the acceptability and initial efficacy of an emotional self-awareness treatment at reducing alexithymia and emotion dysregulation in participants with traumatic brain injury (TBI).

SETTING

An outpatient rehabilitation hospital.

PARTICIPANTS

Seventeen adults with moderate to severe TBI and alexithymia. Time postinjury ranged 1 to 33 years.

DESIGN

Within subject design, with 3 assessment times: baseline, posttest, and 2-month follow-up.

INTERVENTION

Eight lessons incorporated psychoeducational information and skill-building exercises teaching emotional vocabulary, labeling, and differentiating self-emotions; interoceptive awareness; and distinguishing emotions from thoughts, actions, and sensations.

MEASURES

Toronto Alexithymia Scale-20 (TAS-20); Levels of Emotional Awareness Scale (LEAS); Trait Anxiety Inventory (TAI); Patient Health Questionnaire-9 (PHQ-9); State-Trait Anger Expression Inventory (STAXI); Difficulty With Emotion Regulation Scale (DERS); and Positive and Negative Affect Scale (PANAS).

RESULTS

Thirteen participants completed the treatment. Repeated-measures analysis of variance revealed changes on the TAS-20 (P = .003), LEAS (P < .001), TAI (P = .014), STAXI (P = .015), DERS (P = .020), and positive affect (P < .005). Paired t tests indicated significant baseline to posttest improvements on these measures. Gains were maintained at follow-up for the TAS, LEAS, and positive affect. Treatment satisfaction was high.

CONCLUSION

This is the first study published on treating alexithymia post-TBI. Positive changes were identified for emotional self-awareness and emotion regulation; some changes were maintained several months posttreatment. Findings justify advancing to the next investigational phase for this novel intervention.

Anger Self-Management Training for Chronic Moderate to Severe Traumatic Brain Injury: Results of a Randomized Controlled Trial

OBJECTIVE

To test efficacy of 8-session, 1:1 treatment, anger self-management training (ASMT), for chronic moderate to severe traumatic brain injury (TBI).

SETTING

Three US outpatient treatment facilities.

PARTICIPANTS

Ninety people with TBI and elevated self-reported anger; 76 significant others (SOs) provided collateral data.

DESIGN

Multicenter randomized controlled trial with 2:1 randomization to ASMT or structurally equivalent comparison treatment, personal readjustment and education (PRE). Primary outcome assessment 1 week posttreatment; 8-week follow-up.

PRIMARY OUTCOME

Response to treatment defined as 1 or more standard deviation change in self-reported anger.

SECONDARY OUTCOMES

SO-rated anger, emotional and behavioral status, satisfaction with life, timing of treatment response, participant and SO-rated global change, and treatment satisfaction.

MAIN MEASURES

State-Trait Anger Expression Inventory-Revised Trait Anger (TA) and Anger Expression-Out (AX-O) subscales; Brief Anger-Aggression Questionnaire (BAAQ); Likert-type ratings of treatment satisfaction, global changes in anger and well-being.

RESULTS

After treatment, ASMT response rate (68%) exceeded that of PRE (47%) on TA but not AX-O or BAAQ; this finding persisted at 8-week follow-up. No significant between-group differences in SO-reported response rates, emotional/behavioral status, or life satisfaction. ASMT participants were more satisfied with treatment and rated global change in anger as significantly better; SO ratings of global change in both anger and well-being were superior for ASMT.

CONCLUSION

ASMT was efficacious and persistent for some aspects of problematic anger. More research is needed to determine optimal dose and essential ingredients of behavioral treatment for anger after TBI.

Effectiveness of an anger control program among veterans with PTSD and other mental health issues: A comparative study

OBJECTIVE

This study examines the effectiveness of an anger management program among veterans with posttraumatic stress disorder (PTSD) and other mental health issues.

METHOD

Veterans with (n = 76) and without (n = 58) PTSD completed anger management groups at the Crescenz Veterans Affairs Medical Center. Self-rated checklists of anger and PTSD symptoms (for those with PTSD) were completed before and after the group.

RESULTS

Significant improvement in anger was observed in the overall sample (p < .001) but did not differ based on PTSD diagnosis. No significant PTSD symptom changes were observed.

CONCLUSIONS

Veterans with broad mental health concerns benefited significantly from this anger management program, consistent with prior research. Implications for program improvement and future research are discussed.

21st Century Cognitive Behavioural Therapy for Anger: A Systematic Review of Research Design, Methodology and Outcome

Background:Past reviews of cognitive behavioural therapy (CBT) for anger have focused on outcome in specific subpopulations, with few questions posed about research design and methodology. Since the turn of the century, there has been a surge of methodologically varied studies awaiting systematic review.Aims:The basic aim was to review this recent literature in terms of trends and patterns in research design, operationalization of anger, and covariates such as social desirability bias (SDB). Also of interest was clinical outcome.Method:After successive culling, 42 relevant studies were retained. These were subjected to a rapid evidence assessment (REA) with special attention to design (ranked on the Scientific Methods Scale) measurement methodology (self-monitored behaviour, anger questionnaires, and others’ ratings), SDB assessment, and statistical versus clinical significance.Results:The randomized controlled trial characterized 60% of the studies, and the State Trait Anger Expression Inventory was the dominant measure of anger. All but one of the studies reported statistically significant outcome, and all but one of the 21 studies evaluating clinical significance laid claim to it. The one study with neither statistical nor clinical significance was the only one that had assessed and corrected for SDB.Conclusions:Measures remain relatively narrow in scope, but study designs have improved, and the outcomes suggest efficacy and clinical effectiveness. In conjunction with previous findings of an inverse relationship between anger and SDB, the results raise the possibility that the favourable picture of CBT for anger may need closer scrutiny with SDB and other methodological details in mind.

Mild traumatic brain injury and suicide risk among a clinical sample of deployed military personnel: Evidence for a serial mediation model of anger and depression

Research has demonstrated a robust link between traumatic brain injuries (TBIs) and suicide risk. Yet, few studies have investigated factors that account for this link. Utilizing a clinical sample of deployed military personnel, this study aimed to examine a serial meditation model of anger and depression in the association of mild TBI and suicide risk. A total of 149 military service members referred for evaluation/treatment of a suspected head injury at a military hospital participated in the present study (92.6% male; M_age = 27.9y). Self-report measures included the Suicidal Behaviors Questionnaire-Revised (SBQ-R), Automated Neuropsychological Assessment Metrics (ANAM) anger and depression subscales, and Behavioral Health Measure-20 depression subscale. A current mild TBI diagnosis was confirmed by a licensed clinical psychologist/physician. Overall, 84.6% (126/149) of participants met diagnostic criteria for a current mild TBI. Bootstrapped serial mediation analyses indicated that the association of mild TBI and suicide risk is serially mediated by anger and depression symptoms (bias-corrected 95% confidence interval [CI] for the indirect effect = 0.044, 0.576). An alternate serial mediation model in which depression symptoms precede anger was not statistically significant (bias-corrected 95% CI for the indirect effect = -0.405, 0.050). Among a clinical sample of military personnel, increased anger and depression statistically mediated the association of mild TBI and suicide risk, and anger appears to precede depression in this pathway. Findings suggest that therapeutically targeting anger may serve to thwart the trajectory to suicide risk among military personnel who experience a mild TBI. Future research should investigate this conjecture within a prospective design to establish temporality.

Reducing anger outbursts after a severe TBI: a single-case study

Anger outbursts constitute a frequent behavioural issue after a traumatic brain injury (TBI) and have a strong negative impact on the social outcomes resulting from the TBI. However, few studies have examined the efficacy of specific intervention strategies to reduce the frequency and intensity of anger outbursts. We therefore performed a single-case study on this topic by administering two successive and complementary psychological interventions with an AB design with maintenance (first intervention) and an AC design with maintenance plus a one-month follow-up (second intervention) to a patient with a severe TBI. Whereas the first intervention focused on improving the recognition and expression of basic emotions, the second consisted of a self-regulation programme, including various features such as psychoeducation about self-control strategies, relaxation and assertiveness training that aimed to establish adequate behaviours, which were further promoted by an implementation intentions strategy in the patient's daily life. The results indicated that all interventions resulted in a reduced frequency and intensity of anger outbursts, and the data upheld the specificity of these effects. In addition, a meta-analytic integration of the effects of both interventions on the outcomes indicated a medium effect size. Further research is needed on other patients who experience long-standing anger outbursts to examine whether the observed gains can be replicated, sustained on a longer-term basis and improved.

Effectiveness of Interventions to Improve Occupational Performance for People With Psychosocial, Behavioral, and Emotional Impairments After Brain Injury: A Systematic Review

OBJECTIVE

This systematic review evaluates the effectiveness of interventions to improve occupational performance for people with psychosocial, behavioral, or emotional impairments after traumatic brain injury (TBI).

METHOD

Medline, PsycINFO, CINAHL, OTseeker, and the Cochrane Database of Systematic Reviews were searched. Of the 1,512 articles initially identified, 35 met the inclusion criteria.

RESULTS

Six types of interventions were identified: (1) education, (2) peer mentoring, (3) goal-directed therapy, (4) physical activity, (5) skills training, and (6) cognitive-behavioral therapy (CBT). Strong evidence from well-conducted research supports the use of CBT in individual and group settings. Moderate evidence supports goal-directed interventions, aquatic exercise, and functional skills training. Limited evidence supports peer mentoring, aerobic exercise, educational interventions, and various skills training.

CONCLUSION

An increasing body of evidence supports specific interventions to improve occupational performance and participation for people with psychosocial, behavioral, or emotional impairments after TBI.

Non pharmacological treatments for psychological and behavioural disorders following traumatic brain injury (TBI). A systematic literature review and expert opinion leading to recommendations

INTRODUCTION

The non pharmacological approach is an important issue in the treatment of psychological and behavioural disorders in traumatic brain injury (TBI) patients. It remains nevertheless insufficiently known and defined. The objective of this work was to develop precise recommendations for caregivers and relatives.

METHOD

The elaboration of these guidelines followed the procedure validated by the French health authority for good practice recommendations, close to the Prisma statement, involving a systematic, critical review of the literature and the expert opinions of the French Society of Physical Medicine and Rehabilitation (SOFMER) group.

RESULTS

458 articles were identified, among which 98 were selected for their relevance to the theme of the research. None of the studies reached the highest level of evidence. Fifteen controlled studies reached a relatively high level of evidence (level 2); other studies were case series or expert opinions, and other articles again were reviews of the literature and theoretical points of view. The holistic approach structured into programmes, cognitive-behavioural therapy, and family and systemic therapy, despite the low levels of proof, are recommended in first intention at all stages in the evolution of TBI. Relational and adaptive approaches, rehabilitation and vocational approaches, and psychoanalytical therapies may be useful, provided that therapists are familiar with and trained in traumatic brain injury.

CONCLUSION

Despite the small number of publications and a low level of proof, a number of recommendations for the non-pharmacological approach to psychological and behavioural disorders in TBI is proposed by the consensus conference of experts. Scientific research in this domain is needed to confirm and complete these first recommendations.

Anger self-management in chronic traumatic brain injury: protocol for a psycho-educational treatment with a structurally equivalent control and an evaluation of treatment enactment

Anger and irritability are important and persistent clinical problems following traumatic brain injury (TBI). Treatment options include medications, behavioral modification, and psychotherapies, but some are impractical and none have proven efficacy with this population. We describe a randomized multi-center clinical trial testing a novel, one-on-one, 8-session psychoeducational treatment program, Anger Self-Management Training (ASMT), designed specifically for people with TBI who have significant cognitive impairment. The trial is notable for its use of a structurally equivalent comparison treatment, called Personal Readjustment and Education (PRE), which was created for the study and is intended to maximize equipoise for both participants and treaters. Fidelity assessment is conducted in real time and used in therapist supervision sessions. The primary outcome is change in self-reported anger on validated measures from pre-treatment to 1 week after the final session. Secondary outcomes include participant anger as reported by a significant other; emotional distress in domains other than anger/irritability; behavioral functioning; and quality of life. An interim assessment after the 4th session will allow examination of the trajectory of any observed treatment effects, and a follow-up assessment 2 months after the end of intervention will allow examination of persistence of effects. A treatment enactment phase, in which participants are interviewed several months after the last therapy session, is designed to provide qualitative data on whether and to what extent the principles and techniques learned in treatment are still carried out in daily life.

Emotional and behavioral dyscontrol after traumatic brain injury

Emotional and behavioral dyscontrol are relatively common neuropsychiatric sequelae of traumatic brain injury and present substantial challenges to recovery and community participation. Among the most problematic and functionally disruptive of these types of behaviors are pathologic laughing and crying, affective lability, irritability, disinhibition, and aggression. Managing these problems effectively requires an understanding of their phenomenology, epidemiology, and clinical evaluation. This article reviews these issues and provides clinicians with brief and practical suggestions for the management of emotional and behavioral dyscontrol.

Evaluation of the short-term executive plus intervention for executive dysfunction after traumatic brain injury: a randomized controlled trial with minimization

OBJECTIVE

To determine whether the Short-Term Executive Plus (STEP) cognitive rehabilitation program improves executive dysfunction after traumatic brain injury (TBI).

DESIGN

Randomized, waitlist controlled trial with minimization and blinded outcome assessment.

SETTING

Community.

PARTICIPANTS

Participants with TBI and executive dysfunction (N=98; TBI severity 50% moderate/severe; mean time since injury ± SD, 12±14y; mean age ± SD, 45±14y; 62% women; 76% white).

INTERVENTION

STEP program: 12 weeks (9h/wk) of group training in problem solving and emotional regulation and individual sessions of attention and compensatory strategies training.

MAIN OUTCOME MEASURES

Factor analysis was used to create a composite executive function measure using the Problem Solving Inventory, Frontal Systems Behavior Scale, Behavioral Assessment of the Dysexecutive Syndrome, and Self-Awareness of Deficits Interview. Emotional regulation was assessed with the Difficulties in Emotion Regulation Scale. The primary attention measure was the Attention Rating and Monitoring Scale. Secondary measures included neuropsychological measures of executive function, attention, and memory and measures of affective distress, self-efficacy, social participation, and quality of life.

RESULTS

Intention-to-treat mixed-effects analyses revealed significant treatment effects for the composite executive function measure (P=.008) and the Frontal Systems Behavior Scale (P=.049) and Problem Solving Inventory (P=.016). We found no between-group differences on the neuropsychological measures or on measures of attention, emotional regulation, self-awareness, affective distress, self-efficacy, participation, or quality of life.

CONCLUSIONS

The STEP program is efficacious in improving self-reported post-TBI executive function and problem solving. Further research is needed to identify the roles of the different components of the intervention and its effectiveness with different TBI populations.

Rehabilitation Approaches to the Management of Aggressive Behaviour Disorders after Acquired Brain Injury

Symptoms of neurobehavioural disability acquired through brain injury, especially aggression, are associated with severe social handicap. Differences in terminology have resulted in varying estimates, but aggressive behaviour disorder appears to be characteristic of survivors at some point in their recovery journey. This paper provides a brief review regarding the prevalence, development and causes of aggression associated with acquired brain injury (ABI), and what can be done to help manage them. The advantages of using standardised measures conceptualised for ABI in the assessment and formulation of aggressive behaviour disorders are especially highlighted. A range of treatment methods and the evidence base relating to these are described. The contribution of pharmacological therapies, cognitive behavioural therapy and behavioural interventions are explored. It is argued that the strongest evidence base is associated with behaviour therapy, especially when carried out in the context of neurobehavioural rehabilitation, and two case studies are described to illustrate the clinical advantages of interventions derived from operant theory. Comparative lack of ABI experts trained in the management of post-acute behaviour disorders remains a limiting factor.

Anger self-management training for people with traumatic brain injury: a preliminary investigation

OBJECTIVE

: To examine the feasibility and gather preliminary data on the efficacy of a fully manualized, 8-session, psychoeducational treatment for irritability and anger after traumatic brain injury (TBI), called anger self-management training (ASMT).

PARTICIPANTS

: A total of 10 persons with moderate to severe, chronic TBI with significant cognitive impairment and elevated levels of anger and irritability participated in the study; 8 had significant others (SOs) who participated in portions of the treatment and provided pre- and posttreatment measures; 1 SO provided only data.

MAIN OUTCOME MEASURE

: Two subscales of the State-Trait Anger Expression Scale-Revised and Brief Anger-Aggression Questionnaire.

DESIGN

: Pre- to posttreatment pilot study.

RESULTS

: There was significant improvement on all 3 measures of self-reported anger, with large effect sizes (>1.0), and on 1 of 3 SO-reported scales. Qualitative feedback from participants was positive and dropout rate was low (1 of 11).

CONCLUSIONS

: The treatment model represented by the ASMT appears worthy of further study in persons with TBI who have both problematic anger and cognitive impairment.

Combining neuropsychological and cognitive-behavioral approaches for treating psychological sequelae of acquired brain injury

PURPOSE OF REVIEW

Acquired brain injury (ABI) does not only result in physical and cognitive impairments, but may also entail behavioral-emotional difficulties and mental disorders. Although neuropsychological approaches target the rehabilitation of cognitive deficits, the treatment of emotional and behavioral sequelae has received less consideration. This review argues for the integration of cognitive-behavioral approaches into the rehabilitation process and examines respective recent research.

RECENT FINDINGS

Cognitive-behavioral interventions have been investigated in the treatment of behavioral disturbances and mental disorders after ABI. They have also been targeted at supporting adaptive coping with chronic injury-related impairments. Problem-solving approaches of cognitive behavioral therapy may work as meta-models or framework for the rehabilitative process. Unfortunately, most studies reviewed employed methodologically weak designs, which limit convincing conclusions. Still, positive intervention effects have been demonstrated concerning specific outcome measures. Whether these changes also translate into increased psychosocial functioning or quality of life remains unclear.

SUMMARY

Methodologically sound evidence for cognitive-behavioral interventions after ABI is limited, but preliminary results support the effectiveness of these interventions in the treatment of behavioral disorders and emotional disturbances after ABI. Integrating neuropsychological and cognitive-behavioral approaches may therefore prove beneficial to the rehabilitation process.
