SUpporting wellbeing through PEeR-Befriending (SUPERB) feasibility trial: fidelity of peer-befriending for people with aphasia

OBJECTIVE

To evaluate systematically the fidelity of a peer-befriending intervention for people with aphasia.

DESIGN

SUpporting wellbeing through Peer-befriending (SUPERB) was a feasibility randomised controlled trial comparing usual care to usual care +peer-befriending. This paper reports on the fidelity of all intervention aspects (training and supervision of providers/befrienders; intervention visits) which was evaluated across all areas of the Behaviour Change Consortium framework.

SETTING

Community.

PARTICIPANTS

People with aphasia early poststroke and low levels of distress, randomised to the intervention arm of the trial (n=28); 10 peer-befrienders at least 1-year poststroke.

INTERVENTION

Peer-befrienders were trained (4-6 hours); and received regular supervision (monthly group while actively befriending, and one-to-one as and when needed) in order to provide six 1-hour peer-befriending visits over 3 months.

MAIN MEASURES

Metrics included number and length of training, supervision sessions and visits. All training and supervision sessions and one (of six) visits per pair were rated against fidelity checklists and evaluated for inter-rater and intrarater reliability (Gwets AC1 agreement coefficient). Per-cent adherence to protocol was evaluated.

RESULTS

All peer-befrienders received 4-6 hours training over 2-3 days as intended. There were 25 group supervision sessions with a median number attended of 14 (IQR=8-18). Twenty-six participants agreed (92.8%) to the intervention and 21 (80.8%) received all six visits (median visit length 60 min). Adherence was high for training (91.7%-100%) and supervision (83%-100%) and moderate-to-high for befriending visits (66.7%-100%). Where calculable, inter-rater and intrarater reliability was high for training and supervision (Gwets AC1 >0.90) and moderate-to-high for intervention visits (Gwets AC1 0.44-1.0).

CONCLUSION

Planning of fidelity processes at the outset of the trial and monitoring throughout was feasible and ensured good-to-high fidelity for this peer-befriending intervention. The results permit confidence in other findings from the SUPERB trial.

Reporting on novel complex intervention development for adults with social communication impairments after acquired brain injury

PURPOSE

Interventions are often poorly described in published controlled trials, with relatively little information regarding intervention development, content and fidelity. This makes it difficult to conduct replication studies, interpret and compare findings across studies and for therapists to deliver the intervention in clinical practice. Complete reporting of interventions (including fidelity) is now recommended for treatment studies, and this standardized approach is achieved using the Template for Intervention Description and Replication (TIDieR). The aim of this article is to describe the multi-phase process of developing a novel intervention for adults with acquired brain injury (ABI) and report on the findings from involving practicing therapists in this process.

METHODS

Phase 1 involved a review of relevant literature and specifying the intervention as a prototype intervention manual. Phase 2 comprised a focus group with eight practicing therapists exploring their experiences and perceptions of the intervention, potential active components, and essential elements; it also included a review of the prototype manual. Data from the focus group discussion was transcribed and analyzed thematically. Phase 3 investigated actual fidelity of the intervention undertaken, achieved by observers viewing videoed sessions and appraising against the fidelity checklist, which was then analyzed using Cohen's kappa.

RESULTS

Project-based intervention was defined as having six essential elements: a project or tangible end product focus; group-based intervention; individualized communication-based goals; communication partner involvement; acknowledgement and support of participants' cognitive ability; and consideration and plan to address impaired awareness. Analysis of focus group data revealed four themes of essential elements; group context; therapeutic skills; and manual core components and informed the development of a fidelity checklist with 13 essential and 6 desirable criteria. Fidelity assessed using percent agreement was acceptable for almost all rater pairs; where significant, Kappa coefficients had values ranging from poor to excellent (k = 0.34-1.0) depending on rater pair and session.

DISCUSSION

The TIDieR framework provided a clear systematic approach for the complete description and reporting of a complex communication intervention for people with ABI. This article comprehensively described the development and manualisation of intervention in collaboration with practicing therapists which can be used for future testing. In addition, the process undertaken has the potential to inform rehabilitation researchers in other fields on the development of complex interventions.Implications for rehabilitationThe results of this study detail the steps needed to describe an intervention, from the identification of the essential elements through to the creation of a manual and checklist to show fidelity. The process provides a starting point for other rehabilitation researchers developing complex interventions.This article provides a clear and comprehensive description of a novel intervention containing six essential elements for people with acquired brain injury presenting with communication impairments.Project-based intervention is one intervention, which intends to help improve communication skills and quality of life in people with acquired brain injury.This study highlights the important role practicing therapists can play in the creation of an intervention manual and fidelity checklist and in ensuring that sufficient detail is provided to help therapists implement the intervention into clinical practice.

Psychological Intervention in Traumatic Brain Injury Patients

Objective

To provide a brief and comprehensive summary of recent research regarding psychological interventions for patients surviving a traumatic brain injury.

Methods

A bibliographical search was performed in PubMed, Cochrane Library, PsycNET, Scopus, ResearchGate, and Google Scholar online databases. Analysis included distribution by year of publication, age stage of participants (paediatric, adult), location of the research team, study design, type of intervention, and main outcome variables.

Results

The initial search eliciting 1541 citations was reduced to 62 relevant papers. Most publications had adult samples (88.7%). The United States outstands as the country with more research (58.1%); Latin America countries provided no results. Cognitive behavioural therapy (CBT) was the most widely used approach for treatment of (sub)clinical mental disturbances (41.9%). Neuropsychological interventions were scarce (4.8%). Outcome measures included psychiatric disorders (e.g., posttraumatic stress disorder (PTSD), depression, and anxiety) (37.1%), postconcussive symptoms (16.1%), cognitive and functional deficits (48.1%), and social and psychological dimensions (62.9%).

Conclusions

CBT outstands as the preferred therapeutic approach for treating behavioural and emotional disturbances. Also, other related therapies such as dialectical behaviour, mindfulness, and acceptance and commitment therapies have been proposed, and probably in the years to come, more literature regarding their effectiveness will be available. On the other hand, evidence showed that interventions from the field of neuropsychology are minimal if compared with its contribution to assessment. Future research should be aimed at performing studies on more diverse populations (e.g., nonmilitary communities and paediatric and Latin American populations) and at controlling designs to examine the therapeutic efficacy of psychotherapeutic and neurocognitive rehabilitation interventions and compare amelioration by injury severity, age of patients, and clinical profile, in the hopes of creating better guidelines for practitioners.

Toward an evidence-based patient-provider communication in rehabilitation: linking communication elements to better rehabilitation outcomes

Background:

There is a growing interest in linking aspects of patient-provider communication to rehabilitation outcomes. However, the field lacks a conceptual understanding on: (a) ‘how’ rehabilitation outcomes can be improved by communication; and (b) through ‘which’ elements in particular. This article elaborates on the conceptual developments toward informing further practice and research.

Methods:

Existing models of communication in healthcare were adapted to rehabilitation, and its outcomes through a comprehensive literature review.

Results:

After depicting mediating mechanisms and variables (e.g. therapeutic engagement, adjustment toward disability), this article presents the ‘4 Rehab Communication Elements’ deemed likely to underpin rehabilitation outcomes. The four elements are: (a) knowing the person and building a supportive relationship; (b) effective information exchange and education; (c) shared goal-setting and action planning; and (d) fostering a more positive, yet realistic, cognitive and self-reframing.

Discussion:

This article describes an unprecedented, outcomes-oriented approach toward the design of rehabilitation communication, which has resulted in the development of a new intervention model: the ‘4 Rehab Communication Elements’. Further trials are needed to evaluate the impact of this whole intervention model on rehabilitation outcomes.
