Improving Self-awareness After Acquired Brain Injury Leads to Enhancements in Patients’ Daily Living Functionality

Improving self-awareness of prospective memory function after TBI using experiential feedback on a board game activity: An observational study

This study investigated whether experiential and video feedback on performance of prospective memory (PM) tasks embedded within a board game activity improved self-awareness of PM function in adults with moderate-severe traumatic brain injury. An observational pre-post study design with 26 participants from a larger trial of a 6-session PM rehabilitation programme. Sessions 3 and 4 included a board game activity with embedded time-, event-, and activity-based PM tasks. Verbal feedback was provided by therapists during the game and video feedback afterwards. Self-ratings of performance were used to divide the sample into under-estimators (n = 7), accurate estimators (n = 9) and over-estimators (n = 10) of actual PM performance. The discrepancy between self- and therapist ratings of PM performance was measured before and after the game, and following video feedback, and compared between timepoints using non-parametric statistics. Post-task self-evaluations were more accurate than pre-task self-evaluations for the under- and over-estimator groups. Under-estimators showed significant improvement in accuracy of ratings for activity-based PM. Over-estimators showed improvement for event-based PM. Further improvements after video feedback were not significant. The board game activity provided a vehicle for experiential feedback and a means of engaging both those with impaired self-awareness and heightened self-awareness of PM in cognitive rehabilitation.

Life is about "constant evolution": the experience of living with an acquired brain injury in individuals who report higher or lower posttraumatic growth

OBJECTIVE

To explore the experience of living with an Acquired Brain Injury (ABI) in individuals who report higher or lower posttraumatic growth (PTG).

METHOD

A multi-method design was employed. Participant scores on the Posttraumatic Growth Inventory (PTGI) were used to identify groups for qualitative comparative analysis. Individual semi-structured interviews were conducted with fourteen individuals with ABI. Data were analysed thematically.

RESULTS

Four themes emerged. The first two themes: "In my mind I was fine" surviving in aftermath of acquiring a brain injury and The everyday as "derailing" capture the transition process from an initial rehabilitation state characterised by neuropsychological and avoidance coping, towards active rebuilding for PTG. Internal building blocks for PTG and Growing in the social world: "you need to have that social connection" elaborate on the internal (e.g., acceptance, integration of the pre and post-injury self) and external (e.g., social relationships) factors seen to facilitate or obstruct PTG.

CONCLUSIONS

Under certain conditions, individuals living with ABI may construe positive growth from their experiences. Practitioners can support PTG development by providing individual and family-based supports aimed at increasing acceptance, the integration of self, and social connection throughout all stages of ABI rehabilitation.IMPLICATIONS FOR REHABILITATIONInternal factors such as having a flexible and positive mindset and external factors such as one's social environment can affect how individuals living with an ABI construe positive growth.Individuals with ABI and their families require access to individualised longitudinal support for neuropsychological and social challenges that can result in increased distress and obstruct the development of PTG.Efforts to facilitate acceptance and support the integration of the pre and post-injury self through recognition of continuity of self and processing of new schematic beliefs can benefit PTG development.Rehabilitation providers should support individuals with ABI to develop or maintain a positive social identity within new or existing social groups.

Self-Awareness Moderates the Association Between Executive Dysfunction and Functional Independence After Acquired Brain Injury

OBJECTIVE

Impaired self-awareness (SA) is a common symptom after suffering acquired brain injury (ABI) which interferes with patient's rehabilitation and their functional independence. SA is associated with executive function and declarative memory, two cognitive functions that are related to participants' daily living functionality. Through this observational study, we aim to explore whether SA may play a moderator role in the relation between these two cognitive processes and functional independence.

METHOD

A sample of 69 participants with ABI completed a neuropsychological assessment focused on executive function and declarative memory which also included a measure of SA and functional independence. Two separated linear models were performed including functional independence, SA, and two neuropsychological factors (declarative memory and executive function) derived from a previous principal component analysis.

RESULTS

Moderation analysis show a significant interaction between SA and executive function, reflecting an association between lower executive functioning and poorer functional outcome, only in participants with low levels of SA. Notwithstanding, declarative memory do not show a significant interaction with SA, even though higher declarative memory scores were associated with better functional independence.

CONCLUSIONS

SA seems to play a moderator effect between executive function, but not declarative memory, and functional independence. Accordingly, participants with executive deficits and low levels of SA might benefit from receiving specific SA interventions in the first instance, which would in turn positively impact on their functional independence.

Cognitive predictors of self-awareness in patients with acquired brain injury along neuropsychological rehabilitation

Previous research has identified a critical role of executive function and memory in self-awareness, a metacognitive capacity often impaired in acquired brain injury. Through this observational study, we aimed to explore the effect of cognitive rehabilitation on the predictive value of these variables, as also whether any of them can predict the level of self-awareness once the cognitive rehabilitation is completed. 69 patients underwent a neuropsychological assessment, including self-awareness, at admission to and discharge from a cognitive rehabilitation process. Regression analysis was performed at these two moments and a third one was conducted to evaluate whether any of the variables at admission predicted the level of self-awareness at discharge. Verbal fluency was found to be the best predictor of self-awareness, both at admission and discharge. In addition, inhibition and cognitive flexibility, as well as episodic memory, appeared as significant predictors of post-rehabilitation self-awareness. Finally, verbal fluency was revealed as the unique pre-rehabilitation predictor of subsequent level of self-awareness following rehabilitation. While post-acute self-awareness is predicted by non-specific executive measures, the cognitive improvement putatively induced by neuropsychological rehabilitation reveals the contribution of more specific executive and memory functions. Importantly, pre-rehabilitation verbal fluency scores predicted the level of self-awareness after cognitive rehabilitation.
