Behaviour change technique taxonomy: a method of describing head and neck cancer dysphagia intervention delivery

Applying behaviour change theory to speech and language therapy intervention for inducible laryngeal obstruction

BACKGROUND

Speech and language therapists (SLTs) provide interventions for inducible laryngeal obstruction (ILO) despite a current lack of evidence to inform intervention delivery. This study is the first step to develop an evidence-based intervention for ILO, using behaviour change theory and the Behaviour Change Technique Taxonomy version 1 (BCTTv1). Outcomes will inform the early development stage of a complex speech and language therapy intervention for ILO, enabling more precise reporting of ILO intervention studies, as per CONSORT guidelines.

AIMS

(1) To identify whether the BCTTv1 is a useful tool for characterising speech and language therapy interventions for ILO, based on existing literature, current practice and patient interviews. (2) To identify key behaviour change techniques (BCT) used within existing complex speech and language therapy interventions for ILO METHODS AND PROCEDURES: A five-phase study was conducted: (1) a systematic literature search of six electronic databases (Medline, EMBASE, CINAHL (EBSCO), Scopus, Trip, Web of Science) and grey literature between 2008 and 2020; (2) observations of six speech and language therapy intervention sessions; (3) a semi-structured interview with an SLT to validate the observed BCTTs; (4) consensus from four national expert SLTs regarding application of synthesised BCTT data to their own experiences of ILO interventions; and (5) patient engagement to review and comment on findings.

OUTCOMES AND RESULTS

Forty-seven BCTs in total were coded across all three sources. Thirty-two BCTs were identified in clinical observations; 31 in interviews with SLTs and 18 in the literature. Only six BCT were identified in all three sources. Expert SLTs confirmed clinical application and relevance. Patients reported finding the concept of BCT challenging but highlighted the value of psychoeducation to support their understanding of symptoms and in turn to understand the rationale behind speech and language therapy intervention recommendations.

CONCLUSION

This study indicates that the BCTTv1 is a suitable framework to identify and describe intervention components used within speech and language therapy interventions for ILO. A practice-research gap exists, reinforcing that existing literature does not capture the complexity of speech and language therapy intervention for ILO. Further research is needed to develop our understanding of the BCTs that support optimal behaviour change for this patient group.

WHAT THIS PAPER ADDS

What is already known on the subject There is growing recognition for the value of speech and language therapists (SLTs) in delivering complex interventions for patients with inducible laryngeal obstruction (ILO), including evidence to suggest that their intervention can improve quality of life for patients and reduce excessive healthcare use. There are, however, no randomised controlled trials in this field; thus it is unclear what constitutes the most effective intervention. What this study adds This study demonstrates the complexity of speech and language therapy interventions for ILO and highlights the practice-research gap. It identifies a range of behaviour change techniques that are used in existing practice and captures patient views relating to the components identified within this study. What are the clinical implications of this work? Findings highlight the value of providing education about factors that might be driving ILO symptoms and in turn the importance of sharing with patients the rationale for treatment recommendations that necessitate a change in their behaviours. Identified behaviour change techniques can be used when developing and implementing SLT interventions for ILO.

Tele-practice for children and young people with communication disabilities: Employing the COM-B model to review the intervention literature and inform guidance for practitioners

BACKGROUND

Many healthcare and educational services providers have undergone a rapid transition from a face-to-face to a tele-practice mode of service delivery in the context of the COVID-19 outbreak. This, in turn, has led to a need to understand better the evidence underpinning such moves. Based on a review of existing reviews, this paper critically analyses the relevant literature related to intervention with children with communication disabilities drawing on the COM-B model.

METHODS & PROCEDURES

Ten reviews were identified following a systematic searching of electronic databases. These were then coded according to both PRISMA criteria and the components of the COM-B model. Based on these findings, a critical analysis of the state of the tele-practice intervention literature is discussed and fed into evidence-based advice for practitioners transitioning to this mode of service delivery.

OUTCOMES & RESULTS

The COM-B mapping suggests that the existing literature has provided primary evidence for physical opportunity and reflective motivation (e.g., participants have the time to take part and the necessary materials, as well as a desire to do it). It has also focused on elements of social opportunity (e.g., having support and prompts from others to take part). However, there are significant gaps in the description and analysis of both physical and psychological capability components.

CONCLUSIONS & IMPLICATIONS

Whilst the evidence for tele-practice interventions for children and young people with communication disabilities is growing, it is also lacking a comprehensive framework to support its implementation. In times of rapid transitions, researchers and practitioners alike need to understand how to evaluate comprehensively the impact of changing the mode of intervention delivery. The COM-B model provides a powerful tool to reflect on the key elements for the successful design and implementation of tele-practice interventions. What this paper adds What is already known on this subject Tele-practice has been a feature of service delivery for speech and language therapists working with children and young people with speech and language disorders for many years, as it has in other areas of practice. This came into sharp focus during 2020 during the 'lock-down' following the start of the COVID-19 pandemic when most practice went online. What this paper adds to existing knowledge This study set out to provide a framework for understanding service delivery, drawing on the COM-B behaviour change model. This is applied using a rapid review methodology to 10 systematic and narrative reviews of the existing literature published since 2005. The findings suggest that while most studies demonstrated efficacy, there was a lack of information regarding specific aspects of the model which would affect their implementation. What are the potential or actual clinical implications of this work? It is anticipated that the paper has the potential to have a direct bearing on how tele-practice services for children and young people with speech and language disorders will be delivered in the future. The paper concludes with a series of recommendations for practice and research in terms of the application of the COM-B model to tele-practice in speech and language therapy.
