RESUMO

OBJECTIVES: Physical distancing, defined as keeping 1-2m apart when co-located, can prevent cases of droplet or aerosol transmitted infectious diseases such as SARS-CoV2. During the COVID-19 pandemic, distancing was a recommendation or a requirement in many countries. This systematic review aimed to determine which interventions and behavior change techniques (BCTs) are effective in promoting adherence to distancing and through which potential mechanisms of action (MOAs). METHODS: Six databases were searched. The review included studies that were (a) conducted on humans, (b) reported physical distancing interventions, (c) included any comparator (e.g., pre-intervention versus post-intervention; randomized controlled trial), and (d) reported actual distancing or predictors of distancing behavior. Risk of bias was assessed using the Mixed Methods Appraisal Tool. BCTs and potential MoAs were identified in each intervention. RESULTS: Six articles (with seven studies and 19 comparisons) indicated that distancing interventions could successfully change MoAs and behavior. Successful BCTs (MoAs) included feedback on behavior (e.g., motivation); information about health consequences, salience of health consequences (e.g., beliefs about consequences), demonstration (e.g., beliefs about capabilities), and restructuring the physical environment (e.g., environmental context and resources). The most promising interventions were proximity buzzers, directional systems, and posters with loss-framed messages that demonstrated the behaviors. CONCLUSIONS: The evidence indicates several BCTs and potential MoAs that should be targeted in interventions and highlights gaps that should be the focus of future research.

RESUMO

INTRODUCTION: Intervention fidelity concerns the degree to which interventions are implemented as intended. Fidelity frameworks propose fidelity is a multidimensional concept relevant at intervention designer, provider, and recipient levels; yet the extent to which it is assessed multidimensionally is unclear. Smoking cessation interventions are complex, including multiple components, often delivered over multiple sessions and/or at scale in clinical practice; this increases susceptibility variation in the fidelity with which they are delivered. This review examined the extent to which five dimensions from the Behaviour Change Consortium fidelity framework (design, training, delivery, receipt, and enactment) were assessed in fidelity assessments of smoking cessation interventions (randomised control trials (RCTs)). METHODS: Five electronic databases were searched using terms "smoking cessation," "interventions," "fidelity," and "randomised control trials." Eligible studies included RCTs of smoking cessation behavioural interventions, published post 2006 after publication of the framework, reporting assessment of fidelity. The data extraction form was structured around the framework, which specifies a number of items regarding assessment and reporting of each dimension. Data extraction included study characteristics, dimensions assessed, data collection, and analysis strategies. A score per dimension was calculated, indicating its presence. RESULTS: 55 studies were reviewed. There was a wide variability in data collection approaches used to assess fidelity. Fidelity of delivery was the most commonly assessed and linked to the intervention outcomes (73% of the studies). Fidelity of enactment scored the highest according to the framework (average of 92.7%), and fidelity of training scored the lowest (average of 37.1%). Only a quarter of studies linked fidelity data to outcomes (27%). CONCLUSION: There is wide variability in methodological and analytical approaches that precludes comparison and synthesis. In order to realise the potential of fidelity investigations to increase scientific confidence in the interpretation of observed trial outcomes, studies should include analyses of the association between fidelity data and outcomes. Findings have highlighted recommendations for improving fidelity evaluations and reporting practices.

RESUMO

BACKGROUND: This study aimed to explore the barriers and enablers to quitting khat from the perspective of users and the barriers and enablers to supporting users to quit from the perspective of healthcare professionals (HCPs). METHODS: The present qualitative study was conducted using semi-structured interviews and the Theoretical Domains Framework (TDF) to collect and analyse data. FINDINGS: Overall, 10 khat users and 3 professionals were interviewed. Beliefs about the consequences of continued use facilitated user's decisions to quit. Social influences were both a barrier and an enabler. For professionals, the social influence of other colleagues and working together was key in enabling them to support clients. Social/professional role and identity was also an important enabler, as professionals saw supporting users to quit as an integral part of their role. A range of behaviour change techniques was identified as potential ways in which quitting attempts could be more successful, from the perspective of users and professionals. CONCLUSION: The study reveals the complexity of khat chewing and quitting from the perspective of khat users, such as the varied influence of family and friends. It also identifies the many barriers and enablers that professionals experience when supporting individuals to quit, such as working with other professionals. There is little evidence for the effectiveness of current services provided for quitting khat or little information outlining how they were developed. Current services would benefit from evaluating the effectiveness of the interventions using established methodology. Recommendations have been provided for practice in the field of substance misuse.
