Communication training for paid caregivers of people with traumatic brain injury (TBI)

Communication impairments are common following traumatic brain injury (TBI) and affect the ability of a person with TBI to have successful conversations. Ylvisaker, Sellers and Edelman (1998) argue that training to improve the communication skills of an everyday support person would impact on the functioning of a person with TBI. Paid caregivers are often involved to support people with TBI, however, little attention has been focused directly on improving their interaction skills. Therefore, this thesis describes a study conducted to investigate the effect of a communication training program on improving the conversational interactions between paid caregivers and people with TBI. Participants were 10 paid caregivers randomly selected and allocated to either a control or training group. Treatment comprised a 17 hour program (across 6 weeks) that combined collaboration and elaboration conversational strategies (Ylvisaker et al., 1998) with discourse activities (Togher, McDonald, Code, & Grant, 2004). Two conversational interactions (i.e. structured and casual conversations) were videotaped pretraining, posttraining and at 6 months follow-up. The conversations were rated by two independent judges. In addition, focused interviews were conducted pre and posttraining to explore the experiences of trained paid caregivers. Training for paid caregivers improved their structured conversational interactions with people with TBI. Independent raters perceived these interactions to be more appropriate, more rewarding and more interesting compared to a control group. Trained paid caregivers made greater improvements in their ability to acknowledge and reveal the competence of a person with TBI. Improvements were maintained for six months. No significant changes were found for the casual conversational interactions. Findings from the focused interviews revealed that trained paid caregivers reported improvements in their knowledge of effective communicative strategies. This perceived improvement led to interactions reported as more enjoyable and successful and less frustrating. Trained paid caregivers also perceived increased confidence and ability to self-regulate their use of strategies when communicating with people with TBI. Aspects of the training program that were felt to promote or hinder learning were also identified. The findings from this study highlight the importance of training and educating paid caregivers to improve their communication skills. Training can have a significant impact on interactions that involve both paid caregivers and a person with TBI

Training paid caregivers to improve their conversations with people with traumatic brain injury (TBI)

Paid caregivers are frequently involved in the lives of people with TBI with cognitive-communication disorders but no research has evaluated training to improve their interactions. This paper describes an RCT that evaluates a communication partner-training program for paid caregivers of people with TBI. Training was found to improve the skills of paid caregivers and have a significant impact on conversations that involved people with TBI. The long-term effectiveness of the intervention was demonstrated with skills maintained at 6-months follow-up. This research has implications for health professionals that work both with paid caregivers and people with severe TBI

Developing, monitoring, and reporting of fidelity in aphasia trials: Core recommendations from the collaboration of aphasia trialists (CATs) trials for aphasia panel

Background: Developing, monitoring, and reporting of fidelity are essential and integral components to the design of randomised controlled trials (RCTs) in stroke and aphasia. Treatment fidelity refers to the degree to which an intervention is delivered as intended and is directly related to the quality of the evidence generated by RCTs. Clear documentation of treatment fidelity in trials assists in the evaluation of the clinical implications of potential benefits attributed to the intervention. Consideration of the implementation requirements of a research-based intervention as intended in a clinical context is necessary to achieve similar outcomes for a clinical population. Despite this, treatment fidelity is rarely reported in RCTs of aphasia intervention. Aim: To describe fidelity strategies and develop core recommendations for developing, monitoring, and reporting of fidelity in aphasia intervention RCTs. Scope: Relevant conceptual frameworks were considered. The Behaviour Change Consortium comprehensive framework of fidelity was adopted. It includes five areas: study design, training providers, delivery of treatment, treatment receipt, and treatment enactment. We explored fidelity in RCTs with a range of complex aphasia interventions (e.g., ASK, Big CACTUS, COMPARE, FCET2EC, POLAR, SUPERB, and VERSE) and described how different trial design factors (e.g., phase of trial, explanatory vs. pragmatic, number and location of sites, and number and type of treatment providers) influenced the fidelity strategies chosen. Strategies were mapped onto the five areas of the fidelity framework with a detailed exploration of how fidelity criteria were developed, measured, and monitored throughout each trial. This information was synthesised into a set of core recommendations to guide aphasia researchers towards the adequate measurement, capture, and reporting of fidelity within future aphasia intervention studies. Conclusions/Recommendations: Treatment fidelity should be a core consideration in planning an intervention trial, a concept that goes beyond treatment adherence alone. A range of strategies should be selected depending on the phase and design of the trial being undertaken and appropriate investment of time and costs should be considered

‘Emotion is of the essence. … Number one priority’: A nested qualitative study exploring psychosocial adjustment to stroke and aphasia

Background: Stroke and aphasia can have a profound impact on people's lives, and depression is a common, frequently persistent consequence. Social networks also suffer, with poor social support associated with worse recovery. It is essential to support psychosocial well-being post-stroke, and examine which factors facilitate successful adjustment to living with aphasia. Aims: In the context of a feasibility randomized controlled trial of peer-befriending (SUPERB), this qualitative study explores adjustment for people with aphasia in the post-acute phase of recovery, a phase often neglected in previous research. Methods & Procedures: Semi-structured interviews were conducted with 20 people with aphasia and 10 significant others, who were purposively sampled from the wider group of 56 people with aphasia and 48 significant others. Interviews took place in participants’ homes; they were analysed using framework analysis. Outcomes & Results: Participants with aphasia were 10 women and 10 men; their median (interquartile range—IQR) age was 70 (57.5–77.0) years. Twelve participants had mild aphasia, eight moderate–severe aphasia. Significant others were six women and four men with a median (IQR) age of 70.5 (43–79) years. They identified a range of factors that influenced adjustment to aphasia post-stroke. Some were personal resources, including mood and emotions; identity/sense of self; attitude and outlook; faith and spirituality; and moving forward. Significant others also talked about the impact of becoming carers. Other factors were external sources of support, including familial and other relationships; doctors, nurses and hospital communication; life on the ward; therapies and therapists; psychological support, stroke groups; and community and socializing. Conclusions & Implications: To promote adjustment in the acute phase, hospital staff should prioritize the humanizing aspects of care provision. In the post-acute phase, clinicians play an integral role in supporting adjustment and can help by focusing on relationship-centred care, monitoring mental health, promoting quality improvement across the continuum of care and supporting advocacy. What this paper adds What is already known on the subject Anxiety and depression are common consequences of stroke, with depression rates high at 33% at 1 year post-onset. There is evidence that the psychological needs of people with aphasia are even greater than those of the general stroke population. Social support and social networks are also negatively impacted. Few studies have examined adjustment when people are still in hospital or in the early stages of post-stroke life in the community (< 6 months). Further, many stroke studies exclude people with aphasia. What this paper adds to existing knowledge Adjustment to living with stroke and aphasia begins in the early stages of recovery. While this partly depends on personal resources, many factors depend on external sources of help and support. These include doctors, nurses and hospital communication, their experience of life on the ward, and their therapists’ person-centred care. What are the potential or actual clinical implications of this work? Clinicians play an integral role in facilitating people with aphasia to utilize their personal resources and support systems to adjust to life after stroke. They can help by focusing on relationship-centred care, monitoring mental health, promoting quality improvement across the continuum of care and supporting advocacy
