Adherence to medication in adults with Cystic Fibrosis: An investigation using objective adherence data and the Theoretical Domains Framework

Objectives Adherence to nebulizer treatment in adults with Cystic Fibrosis (CF) is poor, and interventions are needed. This research aimed to identify the factors affecting nebulizer adherence using the Theoretical Domains Framework (TDF) and to compare these for participants with different levels of adherence. Design Data‐prompted interviews using the TDF. Methods Eighteen semi‐structured interviews were conducted with adults with CF during which objectively measured adherence data were discussed. Framework analysis was used to code the data into TDF domains, and inductive qualitative content analysis was used to code different beliefs and experiences. Aspects of the TDF that differed between participants with different adherence levels were explored. Results Factors influencing adherence to treatment included all 14 domains of the TDF, 10 of which appeared to vary by adherence level: Skills; Memory and decision‐making; and Behavioural regulation; Environmental context and resources; Social influences; Beliefs about consequences; Beliefs about capability; Reinforcement; Social role and identify; Intentions; Optimism; and Emotions. Conclusions This study is the first to use objectively measured adherence data in a data‐prompted interview using the TDF framework to systematically assess the full range of factors potentially influencing adherence. The results highlighted that interventions need to consider issues of capability, opportunity, and motivation. Interventions that challenge dysfunctional beliefs about adherence and which support the development of routines or habits and problem‐solving may be particularly useful for adults with CF

When is forgetting not forgetting? A discursive analysis of differences in forgetting talk between adults with cystic fibrosis with different levels of adherence to nebulizer treatments

Forgetting is often cited as a reason why people struggle to adhere to treatments for chronic conditions. Interventions have tried to improve forgetting behavior using reminders. We used a discursive psychological approach to explore differences in how high and low adherers constructed forgetting their nebulizer treatments for cystic fibrosis. Interviews were conducted with 18 adults from a cystic fibrosis center in the United Kingdom. High adherers constructed forgetting treatments as occasional lapses in automaticity and temporary lapses in memory that they found easy to repair. Low adherers utilized forgetting to normalize more consistent nonadherence to treatments. However, it is important to contextualize forgetting as a discursive resource that helped these participants to negotiate moral discourses around adherence to treatment that reminder interventions cannot address; we therefore recommend a more behavioral, patient-focused, theory-driven approach to intervention development

Identification of Affective- and Social-Reinforcement Functions of Driven Exercise: Evidence From Three Samples

Driven exercise is a transdiagnostic maladaptive behavior, especially common in eating disorders (EDs); however, its maintenance mechanisms remain poorly understood. To address this gap, we examined the applicability of previously empirically derived and validated reinforcement-function models in explaining driven-exercise maintenance in studies varying across developmental stages and clinical presentations (Study 1: N = 279 adolescents/adults oversampled for EDs; Study 2: N = 118 adolescent/adult inpatients with severe EDs; Study 3: N = 52 adults oversampled for athletes and/or EDs). Results supported the utility of a four-function model (automatic positive reinforcement [APR]/automatic negative reinforcement [ANR; increase positive/decrease negative affect], social positive reinforcement [SPR]/social negative reinforcement [SNR; engage in/avoid interpersonal situations]) in explaining driven exercise. APR was most frequently endorsed, followed by ANR, SNR, and SPR in all studies. APR correlated with last-month driven-exercise episodes across studies; associations between other functions and ED psychopathology varied between studies. Furthermore, results suggested a separate control function could be considered in samples with more severe EDs

Mechanisms of action of a web-based intervention with health professional support to increase nebulizer adherence in adults with cystic fibrosis: a qualitative interview study

Background: Adherence to nebulizer treatments in adults with cystic fibrosis (CF) is often low. A new complex intervention to help adults with CF increase their adherence to nebulizer treatments was tested in a pilot randomized controlled trial (RCT) in 2 UK CF centers. Patients used a nebulizer with electronic monitoring capabilities that transferred data automatically to a digital platform (CFHealthHub) to monitor adherence over time and to a tailored website to display graphs of adherence data and educational and problem-solving information about adherence. A trained interventionist helped patients identify ways to increase their adherence. Objective: This study aims to explore the mechanisms of action underpinning the intervention. Methods: A qualitative interview study was conducted concurrently with a pilot RCT. In total, 25 semistructured interviews were conducted with 3 interventionists at 2 time points, 14 patients in the intervention arm of the trial, and 5 members of the multidisciplinary teams offering wider care to patients. A framework approach was used for the analysis. Results: The intervention was informed by a theoretical framework of behavior change. There was evidence of the expected behavior change mechanisms of action. There was also evidence of additional mechanisms of action associated with effective telehealth interventions for self-management support: relationships, visibility, and fit. Patients described how building a relationship with the interventionist through face-to-face visits with someone who cared about them and their progress helped them to consider ways of increasing adherence to medication. Rather than seeing the visibility of adherence data to clinicians as problematic, patients found this motivating, particularly if they received praise about progress made. The intervention was tailored to individuals, but there were challenges in how the intervention fitted into some patients’ busy lives when delivered through a desktop computer. Conclusions: The mechanisms of action associated with effective telehealth interventions for self-management operated within this new intervention. The intervention was modified to strengthen mechanisms of action based on these findings, for example, delivery through an app accessed via mobile phones and then tested in an RCT in 19 UK CF centers

Clinical Ethics Consultation: Examining how American and Japanese experts analyze an Alzheimer's case

Background: Few comparative studies of clinical ethics consultation practices have been reported. The objective of this study was to explore how American and Japanese experts analyze an Alzheimer's case regarding ethics consultation. Methods: We presented the case to physicians and ethicists from the US and Japan (one expert from each field from both countries; total = 4) and obtained their responses through a questionnaire and in-depth interviews. Results: Establishing a consensus was a common goal among American and Japanese participants. In attempting to achieve consensus, the most significant similarity between Japanese and American ethics consultants was that they both appeared to adopt an "ethics facilitation" approach. Differences were found in recommendation and assessment between the American and Japanese participants. In selecting a surrogate, the American participants chose to contact the grandson before designating the daughter-in-law as the surrogate decision-maker. Conversely the Japanese experts assumed that the daughter-in-law was the surrogate. Conclusion: Our findings suggest that consensus building through an "ethics facilitation" approach may be a commonality to the practice of ethics consultation in the US and Japan, while differences emerged in terms of recommendations, surrogate assessment, and assessing treatments. Further research is needed to appreciate differences not only among different nations including, but not limited to, countries in Europe, Asia and the Americas, but also within each country
