Analysis of Discourse Production to Assess Cognitive Communication Deficits Following Mild Traumatic Brain Injury With and Without Posttraumatic Stress

Experiences of Acquired Brain Injury as Expressed Through Mask-Making: A Qualitative Analysis

PURPOSE

Acquired brain injury (ABI) extends beyond the immediate aftermath, and understanding individual experience of ABI is paramount to providing effective support mechanisms. This study examined how people with ABI used mask-making to engage in self-expression.

METHOD

Publicly available data from the Unmasking Brain Injury Project website, an advocacy group for people with ABI, were analyzed. A qualitative approach with hybrid inductive/deductive analysis was used to explore how people with ABI use art to express their emotional experiences of ABI.

RESULTS

In total, 1,049 masks had narratives describing the visual components and meaning in the associated masks. Three major themes emerged: the multiplicity of experiences after ABI, including positive, negative, and mixed outcomes; the expression of emotional pain and living with loss through art; and the importance of positivity, purpose, and faith in the experience with ABI. Multiplicity was the central expression represented in the masks. The most commonly represented emotional experiences were: emotional pain and living with loss and positivity, purpose, and faith. The masks incorporated literal depictions of the ABI, visual metaphors, and intentional use of colors and shapes for self-expression.

CONCLUSIONS

These results support previous findings that emotional experiences after ABI are complex and often interlaced with several emotions. The most prominent feelings include emotional pain and living with loss, and positivity, purpose, and faith. Mask-making may be a particularly appropriate method for people with ABI to process or express emotional experiences, as well as to provide clinicians with visual records of sense of self, coping, or progress.

Narrative Discourse Performance in Traumatic Brain Injury: Does Story Comprehension Predict Story Retelling?

PURPOSE

Little is known about the relationship between discourse comprehension and production in traumatic brain injury (TBI), especially for spoken language. This study examined to what extent narrative discourse comprehension accounts for narrative discourse production outcomes (story grammar, story completeness). A secondary aim was to provisionally test an assumption of a discourse model, the structure building framework (SBF), that discourse comprehension and production share cognitive processes by investigating the strength of the relationship between them.

METHOD

Twenty-one individuals with TBI completed story comprehension and story retelling tasks. Discourse measures included the Discourse Comprehension Test, a picture story comprehension task, story grammar, and story completeness. Correlational and multiple regression analyses were performed using comprehension measures as predictors for production measures.

RESULTS

There were significant moderate-to-large correlations between all comprehension and production measures. Comprehension measures approached but did not reach significance for predicting story grammar performance but strongly predicted story completeness outcomes.

CONCLUSIONS

The story comprehension measures likely tapped content aspects of discourse more so than organization. Results provided support for a link between content-focused discourse comprehension measures and discourse production outcomes, which may have clinical implications for approaches to discourse intervention. Findings were interpreted as providing preliminary support for the SBF's claim that discourse production deploys the same processes involved in discourse comprehension.

Wishes, beliefs, and jealousy: use of mental state terms in Cinderella retells after traumatic brain injury

Introduction

Traumatic brain injury (TBI) negatively impacts social communication in part due to social cognitive difficulties, which may include reduced mental state term (MST) use in some discourse genres. As social cognitive difficulties can negatively impact relationships, employment, and meaningful everyday activities, assessing and treating these difficulties post-TBI is crucial. To address knowledge gaps, the present study examined MST use in the narrative retells of adults with and without severe TBI to compare between-group performance, evaluate changes over the first two years post-TBI, and investigate the impact of participant and injury-related variables.

Methods

The total number of MSTs, ratio of MSTs to total utterances, and diversity of MSTs were identified in the Cinderella narratives of 57 participants with no brain injury and 57 with TBI at 3, 6, 9, 12, and 24-months post-TBI.

Results

Reduced MST use in participants with TBI was found at 3, 6, 9, and 12-months post-TBI, but these reductions disappeared when story length (total utterances) was accounted for. Further, MST diversity did not differ between groups. Similarly, although the total number of MSTs increased over time post-TBI, no changes were observed in the ratio of MSTs to total utterances or MST diversity over time. Injury severity (post-traumatic amnesia duration), years of education, and verbal reasoning abilities were all related to MST use.

Discussion

Overall, although individuals used fewer MSTs in complex story retells across the first year following severe TBI, this reduction reflected impoverished story content, rather than the use of a lower ratio of MSTs. Further, key prognostic factors related to MST use included injury severity, educational attainment, and verbal reasoning ability. These findings have important implications for social communication assessment and treatment targeting social cognition post-TBI.

Communication and Psychosocial Outcomes 2-Years After Severe Traumatic Brain Injury: Development of a Prognostic Model

OBJECTIVE

To examine predictive factors underlying communication and psychosocial outcomes at 2 years post-injury. Prognosis of communication and psychosocial outcomes after severe traumatic brain injury (TBI) is largely unknown yet is relevant for clinical service provision, resource allocation, and managing patient and family expectations for recovery.

DESIGN

A prospective longitudinal inception design was employed with assessments at 3 months, 6 months, and 2 years.

PARTICIPANTS

The cohort included 57 participants with severe TBI (N=57).

SETTING

Subacute and post-acute rehabilitation.

MAIN OUTCOME MEASURES

Preinjury/injury measures included age, sex, education years, Glasgow Coma Scale, and PTA. The 3-month and 6-month data points included speech, language, and communication measures across the ICF domains and measures of cognition. The 2-year outcome measures included conversation, perceived communication skills, and psychosocial functioning. Predictors were examined using multiple regression.

INTERVENTIONS

Not applicable.

RESULTS

The cognitive and communication measures at 6 months significantly predicted conversation measures at 2 years and psychosocial functioning as reported by others at 2 years. At 6 months, 69% of participants presented with a cognitive-communication disorder (Functional Assessment of Verbal Reasoning and Executive Strategies [FAVRES]). The unique variance accounted for by the FAVRES measure was 7% for conversation measures and 9% for psychosocial functioning. Psychosocial functioning at 2 years was also predicted by pre-injury/injury factors and 3-month communication measures. Pre-injury education level was a unique predictor, accounting for 17% of the variance, and processing speed/memory at 3 months uniquely accounted for 14% of the variance.

CONCLUSION

Cognitive-communication skills at 6 months are a potent predictor of persisting communication challenges and poor psychosocial outcomes up to 2 years after a severe TBI. Findings emphasize the importance of addressing modifiable cognitive and communication outcomes variables during the first 2 years after severe TBI to maximize functional patient outcomes.
