Anxiety and information use in family members of brain injured clientsBarrie, Deborah January 2013 (has links)
A research report submitted to the Faculty of Health Sciences, University
of the Witwatersrand, Johannesburg, in partial fulfilment of the
requirements for the degree of Master of Science in Occupational
Therapy.
Johannesburg,
2013 / Whilst patients are in hospital, their families are expected to understand and
remember complex information from the medical team. Previous studies have shown
that high levels of anxiety impair a person’s ability to interpret complex information
and memory recall. It is unknown if family members experience anxiety whilst the
patient is in rehabilitation. The study aimed to determine if family members
experienced anxiety, and whether there was a significant correlation between anxiety
and the length of time the client was admitted to the rehabilitation facility; length of
time since the client’s injury; the FIM measurement of the patient; as well as the
perception of received information by the treating team. A family representative
participated by completing the Hospital Anxiety and Depression Scale (HADS) and
an Information Checklist on three separate occasions during the patient’s stay in a
rehabilitation hospital. Family members were found to be anxious throughout the
period of rehabilitation, with a decreasing trend in the average scores of the HADS
assessment. An increasing trend was noted in the satisfaction of information offered
by the treating team. No significant correlation could be found between the family
members’ anxiety and the motor or cognitive improvement in the patient – thus
indicating that a strong possibility exists that the factors influencing the family
members’ anxiety are wide spread and diverse.

Head injury survivorship: The family experience.Carson, Paula Penelopy. January 1992 (has links)
Health professionals as well as families are being confronted with long-term care and caregiver issues that accompany the increasing incidence of individuals surviving traumatic brain injury. A sample of parents and brain-injured offspring from 20 families served as informants. The purpose of this study was to identify a qualitatively generated theory describing the parent's experience following a brain-injured child's return to the home setting. An exploratory qualitative design using grounded theory methodology was used during data collection and analysis. All the brain-injured offspring had survived a moderate-to-severe traumatic brain injury; were living with at least one parent; and were ages 17 to 34. A three-phase theory, Investing in the Comeback, was generated using grounded theory methodology. The theory's three stages, centering on fostering independence and seeking stability, describe the work of the parent living with a brain-injured offspring. The first phase, Centering On, involves the parent's focusing attention and behavior primarily on the brain-injured offspring. During Fostering Independence, the second phase, the parent initiates and maintains efforts to promote the offspring's resumption of independent functioning. The final phase, Seeking Stability, consists of the parent working to establish a regime that maintains the brain-injured offspring's optimal performance, while minimizing the strain on other family members. Theoretical sampling guided the identification of categories, properties, conditions, and consequences of each phase. Four quantitative measures supplied descriptions of sample characteristics and included demographics, cognitive deficit ratings of the child by the parent and the investigator, and the parent's perception of the family's functioning.

Adaptation of informal care relationships following Acquired Brain InjuryMoore, Helen January 2012 (has links)
The number of informal carers in the UK is rising, yet the dynamics of care within informal care relationships remain poorly understood. The present research examined adaptation of informal care relationships affected by Acquired Brain Injury. The research addresses four pairs of questions: (1a) Are there any disagreements and/or misunderstandings between carers and people with Acquired Brain Injury (PwABI) regarding carer identity? (1b) How can the pattern of divergences be explained? (2a) Are there any disagreements and/or misunderstandings between carers and PwABI regarding PwABI identity? (2b) How can the pattern of divergences be explained? (3a) What strategies do carers and PwABI use in collaboration on a joint task? (3b) Is the type of input provided by carers on the joint task comparable to scaffolding as described in the child development literature? (4a) What happens when carers and PwABI collaborate to fill in the Disability Living Allowance (DLA) claim form? (4b) Why do carers see more disability than PwABI when filling in the DLA form? Four mixed-method data sets were used to answer these questions: (1) numerical ratings given by PwABI and carers to map out convergences and divergences (2) videos of discussions between participants and researcher during rating tasks (3) videos of carers and PwABI engaging in a joint task - planning inviting a friend or relative round for a meal and (4) videos of carers and PwABI filling in part of the DLA claim form. All data was collected from the same 28 PwABI/carer dyads who were two or more years post injury. Chapter 4 addresses questions 1a and 1b. Carers’ and PwABIs’ perspective ratings revealed a number of disagreements regarding carer identity. Carers perceived themselves negatively compared to their partners’ view of them. Regarding question 1b, carers feel negatively about themselves due to difficulties in the transition to the role of ‘carer’. They experience a lack of recognition for this caring role as a result of concealing the burden of care. Carers require more long term support from health services to help them achieve recognition for their role, such as facilitating attendance at support groups. Chapter 5 addresses questions 2a and 2b. Carers’ and PwABIs’ perspective ratings revealed only one disagreement and corresponding misunderstanding regarding PwABI identity. Regarding question 2b, alignment was found between the perspectives of carers and PwABI regarding PwABI due to the relational rating method used. It is carer identity which is the source of most divergences of perspective, not PwABI identity as commonly assumed. Using a relational rating method shows promise as a tool to explore perspectives as it treats all viewpoints as equal and avoids pathologising the perspective of PwABI. Chapter 6 addresses questions 3a and 3b. Analysis of strategies shows that completing a joint task is a collaborative process. Carers direct the background of the task but PwABI are in charge of the foreground, making task decisions. However, carers dominate the process and control where and how PwABI contribute. Regarding question 3b, the interaction meets the criteria for scaffolding in the strategies chosen and the flexibility of collaboration. However, removal of supports is often an unrealistic goal, leading to frustration in carers. Examination of processes of collaboration has elucidated the strategies used by carers and PwABI and can enhance theoretical discussion of the applicability of the scaffolding metaphor for a cognitively impaired adult sample. Chapter 7 address questions 4a and 4b. Disagreements were frequent when completing the DLA form. Contestations were almost exclusively in the direction of carers seeing greater disability than PwABI. Regarding question 4b, carers see greater disability due to the communication required to complete the form. Dyads are forced to confront disability, a pattern of interaction they avoid in everyday life. Carers marginalise PwABI point of view and position themselves as ‘expert’ on the PwABI. Differences in frames of reference regarding audience, aim and scope lead carers to maximise the disability and PwABI to minimise this. The impact of completing complex forms on relationships and identity needs to be considered during development of disability benefit assessment methods. A relational approach which studies both halves of informal care partnerships simultaneously allows us to go beyond outcomes of ABI and affords a greater understanding of processes of adaptation.

Desempenho de indivíduos acometidos por traumatismo cranioencefálico no teste n-back auditivo / Performance of individuals after trauma brain injuries in N-Back auditory taskCalado, Vanessa Tome Gonçalves 06 December 2013 (has links)
INTRODUÇÃO: O termo memória operacional (MO) refere-se a um constructo cognitivo capaz de armazenar e manter a informação acessível para uso determinado por um tempo limitado, possibilitando a manipulação de diversas informações simultâneas e sequenciais como operações matemáticas longas ou complexas, compreensão de palavras pouco frequentes, extensas ou frases complexas. A linguagem está entre as funções cognitivas que dependem do funcionamento da memória operacional e pode estar comprometida em várias condições patológicas, dentre elas o traumatismo cranioencefálico (TCE). Dados da literatura referentes a essa população ainda são restritos ou pouco consistentes. OBJETIVOS: investigar se o teste n-back é uma medida válida para identificar o déficit de memória em pacientes com TCE, estabelecer nota de corte e curva ROC do teste n-back, comparar o desempenho entre os indivíduos saudáveis e aqueles que sofreram TCE, comparar o teste n-back com os testes de linguagem e aspectos da lesão neurológica, tais como gravidade e tempo, tempo de coma e localização hemisférica da lesão nos resultados para verificar o desempenho e a relevância na separação dos casos em pacientes e controles.MÉTODOS: 53 indivíduos brasileiros (26 adultos com TCE e 30 adultos saudáveis) foram avaliados por bateria de estímulos verbais auditivos para verificar diferenças inter-grupos na capacidade de processamento da memória operacional, quanto ao numero de respostas corretas (acurácia), capacidade máxima de processamento na memória operacional (span) e também verificar a relação da memória operacional com habilidades linguísticas, através da comparação de testes. RESULTADOS: na comparação entre os pacientes e os indivíduos do grupo controle observou-se diferença estatisticamente significante entre os grupos tanto para os testes de base quanto para os resultados do n-back. Os grupos foram estatisticamente pareados em relação às variáveis sócio-demográficas (idade, escolaridade e gênero). O modelo estatístico com as variáveis do teste n-back demonstrou ótima separação dos casos em pacientes/ controle com a área sob a curva ROC de 89%. O modelo também mostrou convergência com os testes de linguagem para compreensão auditiva de sentenças, fluência verbal e aspectos discursivos-pragmáticos e com o nível cognitivo. O lado da lesão foi estatisticamente significante para o n-back, fluência verbal e discurso conversacional. CONCLUSÃO: Os resultados mostram que o n-back na maneira como foi desenhado é capaz de diferenciar os indivíduos alterados e os normais na habilidade de memória operacional. No estudo foi possível discriminar o comportamento de indivíduos com lesão encefálica adquirida e indivíduos saudáveis quanto à medida de acurácia e capacidade máxima de manipulação da informação na memória operacional. Esse comportamento reflete o funcionamento linguístico e cognitivo que se correlaciona com o mecanismo de memória operacional / INTRODUCTION: The term working memory (WM) refers to a construct cognitive capability of storing and keeping information on line to a determined use for a limited time, enabling the manipulation of diverse simultaneous and sequential information such as long or complex mathematical operations, comprehension of less frequent words, extensive or complex sentences. The language is among the cognitive functions which depends on the operational memory behavior and may be engaged in many pathological conditions, among them the TBI (traumatic brain injury). Literature dada relative to such population are still restrict or weak. AIM: investigate whether the n -back task is a valid measure for identifying memory deficits in patients with TBI; establish cutoff and ROC curve of n-back task; to compare performance between normals individuals and those who have suffered TBI; to compare n-back task with tests of language and aspects of neurological injury, such as severity, coma and hemispheric laterality of the lesion to verify the performance and relevance in the separation of cases. METHODOS: 53 individuals Brazilians (26 adults with TBI and 30 healthy adults) were assessed by a battery of auditory verbal stimuli for detecting differences between groups in the processing capacity of working memory, as the accuracy and span also check the relationship of working memory to language skills, through the comparison tests. RESULTS: in the comparison between patients and control subjects was observed statistically significant differences between groups thus to the tests as the basis tests as to results of the n -back. The groups were statistically matched in relation to socio-demographic variables (age, education and gender). The statistical model with variables of the n -back test showed good separation of cases where patients / control with the area under the ROC curve of 89 % . The model also showed convergence with language tests for auditory comprehension of sentences, verbal fluency and pragmatic - discursive aspects and the cognitive level. The side of the lesion was statistically significant for the n -back, verbal fluency and conversational discourse. CONCLUSION: the results demonstrated that the n-back on the way it was designed is able to distinguish the changed individuals and the normal on the working memory ability. On the study it was possible to discriminate the behaviors of individuals with acquired brain injury and healthy individuals regarding the accuracy and maximum capacity of manipulating information on the working memory. Such behavior reflects the linguistic and cognitive function which correlates with the working memory mechanism
