Development of a self-management intervention to improve tamoxifen adherence in breast cancer survivors using an Intervention Mapping framework

[Adherence to endocrine therapy: A major issue in breast cancer management]

Endocrine therapy plays a crucial role in the treatment of women with hormone receptor-positive breast cancer. However, non-adherence remains a frequent issue known to negatively impact survival. Based on a comprehensive literature review, this article explores the terminologies employed to describe adherence and methods used for its assessment, the adherence data reported with adjuvant endocrine therapy with targeted therapies, the determinants of adherence or non-adherence, and finally, tested solutions to address it. The results show that a better understanding of the causes of non-adherence would help to better identify patients at risk, and to develop personalized intervention programs capable of improving adherence to adjuvant endocrine therapy. In light of the literature, interventions are likely to require a multimodal approach and integration into our future healthcare pathways.

Using an Intervention Mapping Approach to Improve Adherence to Disease-Modifying Treatment in Multiple Sclerosis

BACKGROUND

Up to 50% of individuals with multiple sclerosis (MS) who are prescribed disease-modifying treatments (DMTs) do not take them as advised. Although many studies report on DMT adherence rate, few studies report on interventions involving individuals with MS. The current paper describes the development of an intervention aimed at improving adherence to DMTs among identified nonadherent individuals with MS.

METHODS

An intervention was developed using an Intervention Mapping approach, recommendations from reviews on medication adherence, and input from individuals with MS. Its content was determined by theories of health behavior (specifically, a perceptions and practicalities approach), empirical evidence collected among the specific target population (an observational "needs assessment" stage [n = 186]), and other studies.

RESULTS

A personalized intervention was tailored to the reasons for nonadherence, uncovered during the observational needs assessment stage, to be delivered sequentially by a neurologist and a psychologist. After the intervention objectives were identified, components of the intervention were set: psychoeducation and ways of coping with adverse effects; modification of unhelpful treatment beliefs (such modifications were found predictive of adherence in the observational phase of the study); improving confidence and self-efficacy; and developing strategies for remembering to take DMTs. These components were embedded within motivational interviewing.

CONCLUSIONS

Intervention Mapping was useful in developing an intervention grounded both in the theoretical approach of perceptions and practicalities and in empirical evidence from the literature and the target sample; concurrently, identifying determinants that the intervention did not address. The effectiveness of the intervention-which could potentially improve adherence among individuals with MS-needs to be examined.

Informing interventions to improve uptake of adjuvant endocrine therapy in women with breast cancer: a theoretical-based examination of modifiable influences on non-adherence

PURPOSE

To inform intervention development, we measured the modifiable determinants of endocrine therapy (ET) non-adherence in women with breast cancer, using the Theoretical Domains Framework (TDF) and examined inter-relationships between these determinants and non-adherence using the Perceptions and Practicalities Approach (PAPA).

METHODS

Women with stages I-III breast cancer prescribed ET were identified from the National Cancer Registry Ireland (N = 2423) and invited to complete a questionnaire. A theoretically based model of non-adherence was developed using PAPA to examine inter-relationships between the 14 TDF domains of behaviour change and self-reported non-adherence. Structural equation modelling (SEM) was used to test the model.

RESULTS

A total of 1606 women participated (response rate = 66%) of whom 395 (25%) were non-adherent. The final SEM with three mediating latent variables (LVs) (PAPA Perceptions: TDF domains, Beliefs about Capabilities, Beliefs about Consequences; PAPA Practicalities: TDF domain, Memory, Attention, Decision Processes and Environment) and four independent LVs (PAPA Perceptions: Illness intrusiveness; PAPA Practicalities: TDF domains, Knowledge, Behaviour Regulation; PAPA External Factors: TDF domain, Social Identity) explained 59% of the variance in non-adherence and had an acceptable fit (χ²(334) = 1002, p < 0.001; RMSEA = 0.03; CFI = 0.96 and SRMR = 0.07) Knowledge had a significant mediating effect on non-adherence through Beliefs about Consequences and Beliefs about Capabilities. Illness intrusiveness had a significant mediating effect on non-adherence through Beliefs about Consequences. Beliefs about Consequences had a significant mediating effect on non-adherence through Memory, Attention, Decision Processesg and Environment.

CONCLUSIONS

By underpinning future interventions, this model has the potential to improve ET adherence and, hence, reduce recurrence and improve survival in breast cancer.

Development of an intervention aimed at the prevention and treatment of chronic pain in breast cancer survivors: An intervention mapping approach

OBJECTIVE

Pain is prevalent among breast cancer survivors and can persist for years, impeding quality of life. Both prevention and pain treatment are important. However, this requires an interdisciplinary approach and complex models of care. We report on the design and implementation of an intervention that follows a step-wise care model, aimed at timely and adequate pain follow-up among breast cancer survivors.

METHODS

We used intervention mapping to guide our planning process. The intervention was developed in co-design with relevant stakeholders, such as breast cancer survivors and healthcare providers.

RESULTS

An e-learning training was developed aimed at changing healthcare providers' knowledge, beliefs, and interprofessional behaviour regarding pain follow-up. Second, guides were produced to empower patients in talking about pain and stimulate referral to other disciplines.

CONCLUSION

To achieve change in pain follow-up, multiple levels should be addressed. Additionally, the implementation and adoption of an intervention opposes challenges. Intervention mapping can serve as a theory-based and data-driven approach for decision-making during planning.

PRACTICE IMPLICATIONS

This study can inform others about how to prepare for the development and implementation of an intervention. The developed intervention can also be adapted according to the target population and context, and used for other cancer populations.

Development of an evidence‑based, theory‑driven, and culturally appropriate character strengths-based intervention for breast cancer patients, following the Medical Research Council Framework

PURPOSE

To design and develop a complex, evidence‑based, theory‑driven, and culturally appropriate character strengths-based intervention (CSI) for breast cancer patients, following the Medical Research Council (MRC) framework.

METHODS

From 2018 September to 2020 November, a complex intervention perspective was adopted. The rationale, methods, and processes employed in carrying out the study were reported. The acceptability and feasibility of intervention program were evaluated as a part of subsequent pilot study. Based on piloting, a refined and optimized definitive intervention was obtained. The development of the intervention is an iterative process involving input from three key stakeholders: experts, medical staff, and patient representatives.

RESULTS

The systematic review revealed CSIs were effective and the selected theory served as a guide and indicated theory-inspired modifications. A representative team of breast cancer patients and oncology nurses collaboratively developed and tailored the intervention content and format with attention to the acceptability and feasibility. Five main strategies, including peripheral, evidential, linguistic, constituent-involving, and sociocultural strategies, were used to achieve and strengthen the cultural appropriateness. After the pilot phase, several refinements were made on the CSI program, such as editorial changes in the booklet or alternative suggestions for difficult strengths-based activities (e.g., outdoor activities). All participants not only expressed satisfaction with the program in process evaluation, but also reported perceived benefits such as enjoyable and sociable experience, better well-being, and increased confidence.

CONCLUSION

Consideration of the MRC framework, theory guidance, and suggestions from stakeholders during intervention development can optimize uptake and sustainability in the clinical setting. It is recommended that randomized controlled trial be used in future studies to assess the intervention, the process and the mechanisms of the intervention. Our approach may offer implications for the design and implementation of similar initiatives to support cancer patients.

Designing a Needs-Oriented Psychological Intervention for Chinese Women Undergoing an Abortion

Accessing good quality abortion care is a fundamental human right and contributes to achieving Sustainable Development Goals. However, well-designed abortion care that meets women's needs is limited. This study aims to systematically develop an intervention to promote the psychological well-being of Chinese women undergoing an abortion. A five-step iterative approach informed by intervention mapping was undertaken to determine the intervention design. Step 1 used in-depth interviews with 14 Chinese women undergoing an abortion to assess real-life stressors and support needs. We identified eight stressors and found women's support needs varied with the time trajectory of the abortion. Step 2 used a focus group discussion with care providers to select modifiable stressors that impact negative psychological outcomes. In Step 3 and Step 4, we determined and integrated the exact strategies to eliminate or mitigate possible modifiable stressors by incorporating information from in-depth interviews and the Transactional Model of Stress and Coping. The integrated strategies were instructional support, informational support, and timely communication. In Step 5, we composed the detailed intervention design according to the best available evidence and, to confirm content validity, consulted 10 women who had undergone abortion in the previous 2-6 weeks. The intervention was titled STress-And-coping suppoRT (START), which included four interacting components: (1) a face-to-face consultation at the first appointment; (2) a printed booklet with information on abortion, self-care, and managing emotions and intimate relationships; (3) a WeChat-based online public profile page offering the same information as the booklet; (4) a telephone hotline. This study paves the way for a new approach to addressing the psychological needs of women experiencing abortion in China. The rigorous process provides an example of developing tailored health promotion interventions.

Adherence to adjuvant endocrine therapy among White British and ethnic minority breast cancer survivors in the United Kingdom

OBJECTIVE

Around half of women do not take adjuvant endocrine therapy (AET) as prescribed. Research suggests that adherence rates vary across ethnic groups. This study compared AET adherences rates in White British women and women from minority ethnic groups in the United Kingdom.

METHODS

This is an observational study with 2001 breast cancer survivors recruited from outpatient clinics. Eligible women were diagnosed with primary breast cancer and prescribed AET within the last 3 years. Adherence was measured using the Medication Adherence Rating Scale. Eligible women were asked to complete a questionnaire pack that collected sociodemographic data such as age, relationship status and ethnicity. Independent samples t tests and χ² tests were used to compare White British women and women from minority ethnic groups on self-reported adherence to AET.

RESULTS

Of White British women, 27.8% were classed as non-adherent, compared to 44.4% of women from minority ethnic groups. A logistic regression controlling for relevant demographics indicated that women from minority ethnic groups had a significantly higher risk of non-adherence than women who were White British (odds ratio = 1.50, p = 0.03) CONCLUSION: Rates of non-adherence to AET are higher in women from minority ethnic groups, which may contribute towards racial disparities in breast cancer outcomes. Research with larger and more diverse samples is needed to explore this further and to investigate the psychosocial factors driving differences in adherence.

Person-centred support programme (RESPECT intervention) for women with breast cancer treated with endocrine therapy: a feasibility study

OBJECTIVE

The peRson-cEntred Support Programme EndoCrine Therapy intervention is a complex intervention encompassing a person-centred support programme for patients with breast cancer being treated with endocrine therapy (ET). The aim of this study was to explore the feasibility of the trial design and patient acceptability of the intervention and outcome measures and to provide data to estimate the parameters required to design the final intervention.

DESIGN

A controlled before-and-after design following the Consolidated Standards of Reporting Trials 2010 statement for feasibility trials.

SETTING

A surgical outpatient clinic in Sweden.

PARTICIPANTS

Forty-one patients (aged 47-85) with breast cancer who were treated with ET.

INTERVENTIONS

Eligible patients were assigned to the control group or intervention group, which included individual education material, an individualised learning plan and a personalised reminder letter using a person-centred approach. The intervention could be delivered as a telephone or digital follow-up during a 12-week follow-up.

OUTCOME MEASURES

The aims were to determine the recruitment rate, assess the rate of retention, explore whether the intervention was delivered according to the protocol, assess the preferred form of educational support, rate of education sessions, length per education session and length between each education session, determine the distribution of education materials and assess completion rates of patient-reported instruments, including the General Self-efficacy Scale, the Quality of Care from the Patient's Perspective Questionnaire and the Memorial Symptom Assessment Scale.

RESULTS

Eighty-six per cent of the patients in the intervention group completed the intervention and questionnaires 3 months after their inclusion. The call attendance was 90%. During the intervention, the contact nurse complied with the intervention protocol. For self-efficacy, symptoms and quality of care, there were no differences in effect size between the control and intervention groups.

CONCLUSIONS

This intervention seems to be feasible and acceptable among patients.

Supporting adjuvant endocrine therapy adherence in women with breast cancer: the development of a complex behavioural intervention using Intervention Mapping guided by the Multiphase Optimisation Strategy

BACKGROUND

Adjuvant endocrine therapy (AET) reduces the risk of breast cancer recurrence and mortality. However, up to three-quarters of women with breast cancer do not take AET as prescribed. Existing interventions to support adherence to AET have largely been unsuccessful, and have not focused on the most salient barriers to adherence. This paper describes the process of developing four theory-based intervention components to support adherence to AET. Our aim is to provide an exemplar of intervention development using Intervention Mapping (IM) with guidance from the Multiphase Optimisation Strategy (MOST).

METHODS

Iterative development followed the six-stage IM framework with stakeholder involvement. Stage 1 involved a literature review of barriers to adherence and existing interventions, which informed the intervention objectives outlined in Stage 2. Stage 3 identified relevant theoretical considerations and practical strategies for supporting adherence. Stage 4 used information from Stages 1-3 to develop the intervention components. Stages 1-4 informed a conceptual model for the intervention package. Stages 5 and 6 detailed implementation considerations and evaluation plans for the intervention package, respectively.

RESULTS

The final intervention package comprised four individual intervention components: Short Message Service to encourage habitual behaviours surrounding medication taking; an information leaflet to target unhelpful beliefs about AET; remotely delivered Acceptance and Commitment Therapy-based guided self-help to reduce psychological distress; and a website to support self-management of AET side-effects. Considerations for implementation within the NHS, including cost, timing and mode of delivery were outlined, with explanation as to how using MOST can aid this. We detail our plans for the final stage of IM which involve feasibility testing. This involved planning an external exploratory pilot trial using a 2^4-1 fractional factorial design, and a process evaluation to assess acceptability and fidelity of intervention components.

CONCLUSIONS

We have described a systematic and logical approach for developing a theoretically informed intervention package to support medication adherence in women with breast cancer using AET. Further research to optimise the intervention package, guided by MOST, has the potential to lead to more effective, efficient and scalable interventions.
