Adding Qualitative and Mixed Methods Research to Health Intervention Studies: Interacting With Differences

Exploring the Acceptability of Behavioral Swallowing Interventions for Head and Neck Cancer Patients During Radiotherapy: A Qualitative Study of Patients' Experience

The PRO-ACTIVE randomized clinical trial offers 3 swallowing therapies to Head and Neck Cancer (HNC) patients during radiotherapy namely: reactive, proactive low- ("EAT-RT" only), and high-intensity ("EAT-RT + exercises"). Understanding the perceived acceptability of these interventions is important to inform eventual implementation into clinical practice. This study explored patients' perspectives using qualitative methodology. At 2 Canadian PRO-ACTIVE trial sites, 24 trial participants were recruited for individual semi-structured interviews, representing each of the 3 trial arms. Data collection and thematic analysis were guided by the Theoretical Framework of Acceptability (TFA). Member checking was conducted through follow-up focus groups. Seven themes were derived reflecting the TFA constructs. Overall, regardless of trial arm, patients reported a positive experience with therapy. Patients identified benefits of EAT-RT therapy, reporting that it provided meaningful feedback on diet progress and supported goal setting for oral intake. Patients who received proactive therapies valued the opportunity to set expectations early, build mealtime routine iteratively over time, and have an extended engagement with the SLP. Regardless of trial arm, patients agreed proactive therapy aligned with what they think is best and that therapy intensity should accommodate individual needs. This study identified the value to HNC patients of receiving swallowing interventions during RT and setting realistic expectations around swallowing. Compared to reactive care, proactive therapies were perceived helpful in consolidating habits early, establishing realistic expectations around swallowing and building an extended rapport with the SLP. These findings will inform the implementation of proactive versus reactive swallowing therapies in clinical practice.

Does feeling what you eat change how you eat? Implications of an intervention to promote consciousness of eating experiences

Introduction

This work aims to understand the experience of participating in the Food and Nutrition Education Program workshops with Sensory and Cognitive Exercises (PESC) and measure its impact on eating behavior.

Methods

The PESC consists of four workshops with exercises stimulating perception and reflection on bodily sensations triggered in eating situations. It was developed to promote consciousness of eating experiences in women who reported difficulty in controlling their body weight and who increased over 5% of their body weight in the previous year. This is a mixed-methods study designed as a controlled trial. The intervention group (n = 19) was evaluated before the first workshop (T0) and after the last workshop (T1) and the control group (n = 18), which did not participate in the workshops, was evaluated twice (T0 and T1), with an interval of 3 to 4 weeks. At T0 and T1, it was applied the Intuitive Eating Scale (IES-2) and the Three Factor Eating Questionnaire (TFEQ-R21). In T1, the intervention group also participated in a qualitative interview.

Results

After participating in the PESC, the intervention group showed an increase in the IES-2 total score (95% Confidence Interval = (0.10, 0.39)) and a decrease in the emotional eating scale score (95% Confidence Interval = (-16.03; -3.85)). The interviews' analysis revealed the participants' self-observation process, which led to the perception of their practices, priorities, intentions, eating difficulties, and the connection between these aspects and environmental issues. The following themes were considered: Food management/control, Body dissatisfaction, Reflection/re-signification, and Different ways of being in familiar contexts.

Discussion

The results allow us to infer that, after participating in the PESC, the intention to manage food intake became more effective, less susceptible to oscillations imposed by the external environment, and more supported by internal resources.

Causality in psychotherapy research: Towards evidential pluralism

Identifying causal relationships is at the heart of all scientific inquiry, and a means to evidence base practices and to guide policymaking. However, being aware of the complexities of interactions and relationships, scientists and academics are cautious about claiming causality. Researchers applying methods that deviate from the experimental design generally abstain from causal claims, reserving them for designs that adhere to the evidential ideals of empiricism (e.g., RCTs), motivated by the Humean conceptions of causality. Accordingly, results from other designs are ascribed lower explanatory power and scientific status. We discuss the relevance of also other perspectives of causality, such as dispositionalism and the power perspectives of various realist approaches, which emphasize intrinsic properties and contextual variations, as well as an inferentialist/epistemic approach that advocates causal explanations in terms of inferences and linguistic interaction. The discussion will be illustrated by the current situation within psychotherapy research and the APA Policy Statement on Evidence-Based Practice. The distinction between difference-making and causal production will be proposed as a possible means to evaluate the relevance of designs. We conclude that clarifying causal relationships is an ongoing process that requires the use of various designs and methods and advocate a stance of evidential pluralism.

Mixed Methods Community-Engaged Evaluation: Integrating Interventionist and Action Research Frameworks to Understand a Community-Building Violence Prevention Program

While mixed methods research can enhance studies of intervention outcomes and projects where research itself transforms communities through participatory approaches, methodologists need explicit examples. As the field of interpersonal violence prevention increasingly embraces community-level prevention strategies, it may benefit from research methods that mirror community-building prevention processes. A multiphase mixed methods study with sequential and convergent components assessed the feasibility, and impact of a prevention program to change social norms and increase collective efficacy in towns. Joint display analysis created a nuanced picture of the acceptability, feasibility, and impact of the program. This article contributes to the field of mixed methods research by bridging discussions of "interventionist" studies with models of community-based participatory mixed methods research into a combined community-engaged method.

Use of mixed methods research in intervention studies to increase young people's interest in STEM: A systematic methodological review

Introduction

Mixed methods research intervention studies integrate quantitative evaluation approaches, such as randomized controlled trials and quasi-experimental designs, with qualitative research to evaluate the effectiveness, efficacy, or other results of an intervention or program. These types of studies, which have attracted growing attention in recent years, enhance the scope and rigor of the evaluation. While various frameworks that summarize the justifications for carrying out these types of studies and provide implementation guidance have been published in the last few years in the health sciences, we do not know whether such frameworks have been properly implemented in the social and educational sciences. This review examined the methodological features and reporting practices of mixed methods intervention studies aimed at increasing young people's interest in STEM.

Methods

A systematic search was carried out in APA PsycNET, ERIC, ProQuest, Scopus, and Web of Science, and a hand search in 20 journals. We included peer-reviewed English-language articles that reported intervention studies with a quantitative component measuring outcomes specific to increasing secondary school students' interest in STEM fields, a qualitative component conducted before, during, or after the quantitative component, and evidence of integration of both components. Qualitative content analysis and ideal-type analysis were used to synthesize the findings.

Results

We found 34 studies; the majority published in the last ten years. Several patterns of mixed methods application were described in these studies, illustrating the unique insights that can be gained by employing this methodology. The reporting quality of the included studies was generally adequate, especially regarding the justification for using a mixed methods intervention design and the integration of the quantitative and qualitative components. Nonetheless, a few reporting issues were observed, such as a lack of detail in the presentation of the mixed methods design, an inadequate description of the qualitative sampling and analysis techniques, and the absence of joint displays for representing integration.

Discussion

Authors must pay attention to these issues to ensure that the insights obtained by the use of mixed methods research are effectively communicated.

Mapping Real-World Data to Self-Reported Information to Explore Determinants of Location Selection for Community Pharmacies in Taiwan

Background

Easy and adequate access to community pharmacies is key to eliminating primary barriers to the utilization of medicines and healthcare services. The location of community pharmacies is important for patients and providers when choosing and opening a pharmacy, but only a handful of studies investigate factors associated with the geographical distribution of pharmacies. This study aimed to identify decisive factors for location selection when starting a pharmacy among districts/townships in Taiwan.

Methods

This cross-sectional mixed mode study employed an explanatory sequential design, beginning with a quantitative analysis of national datasets, and followed by a qualitative analysis of structured interviews. The national data were extracted from the Taiwan government database of 2020, and the qualitative interviews were conducted with 10 community pharmacists through a snowball sampling in 2021. A multiple linear regression was conducted to identify salient predictors of the number of community pharmacies in each of the 368 districts/townships in Taiwan, including population density, median annual household income, number of physician offices, area, and proportion of female residents of each district/township. Ten chief pharmacists were interviewed to share viewpoints on the decision-making process of their selection of current pharmacy practice sites. Inductive thematic analysis was performed to extract factors pertinent to location selection for pharmacy operations and services.

Results

Confirmed by quantitative and qualitative data, population density, numbers of physician offices, median annual household income, pharmacy operation type, and type of retail locations are key determinants for site selection in considering opening a new community pharmacy.

Conclusion

The study uncovers salient factors associated with the choice of community pharmacy location in Taiwan and proposes the adequate number of physician offices that a community pharmacy can collaborate with. In addition, pharmacists should prudently consider if their preferred service features match the needs of residents.

Racism in public health services: A research agenda

Despite racism and its impact on health inequities being increasingly studied in health care settings, racism in public health services has so far been neglected in public health research. Studying racism in public health services provides many opportunities to explore the relationship between racism and health protection. We identify several research themes to be explored on (1) non-stigmatizing and community-driven risk communication, (2) surveillance by public health authorities of racialized minority groups, (3) racism experiences in everyday interactions with public health authorities, (4) legal consequences of encounters with public health authorities and (5) public health infrastructure, structural racism and the intersectionality of marginalization. Tackling these research themes will help to start building an evidence base on how racism interferes with equitable health protection and how to dismantle it.

“Moving on to an Open World”: A Study of Participants’ Experience in Meaningful Activities and Recovery (MA&R)

Background. Meaningful activities and Recovery (MA&R) is a peer coled occupational therapy intervention, to support occupational engagement among persons with psychiatric disabilities. Aim. To investigate participants’ perspectives on how MA&R influenced occupational engagement and recovery processes. Material and Methods. A qualitative study with a phenomenological-hermeneutic design. Individual semistructured interviews were conducted with three women and ten men who had participated in MA&R. Participants were recruited from community mental health centres and municipality mental health services in two Danish municipalities. Analysis strategy was based on Malterud’s Systematic Text Condensation. Results. MA&R was perceived as a practical approach to recovery, by providing an opportunity for reorientation, meaning, making in mundane activities, and a new outlook on everyday life. Participating in MA&R challenged a black and white approach to activities, put emphasis on “the little things”, and enhanced curiosity, presence, and joy in occupational engagement. Conclusion. MA&R supported participants in developing a new “lens” on meaningful activities. The lens enhanced occupational engagement and made it possible to live according to personal preference. Results can inform further development and delivery of recovery-oriented occupational therapy interventions and add to the understandings of how occupational engagement and recovery are intertwined and manifested through everyday experiences. Thus, occupational engagement is an important target for recovery-oriented interventions. Occupational therapists and peer-workers coleading such interventions is feasible and makes good sense to the participants.

Mixed methods intervention studies in children and adolescents with emotional and behavioral disorders: A methodological review

BACKGROUND

Mixed methods intervention studies can improve the accuracy of interventional evaluations in the field of emotional and behavioral disorders by helping researchers gain a more nuanced understanding of how a particular intervention works. However, no studies to date have systematically examined the ways in which this type of studies have been carried out and reported.

AIM

To examine the methodological features and reporting practices found in mixed methods intervention studies in children and adolescents with emotional and behavioral disorders.

METHOD

Methodological review based on a systematic search from inception to July 2021 in Embase, Medline, PsycINFO, and SCOPUS, and a hand search in seven journals.

RESULTS

We found 30 studies, most of them published since 2019. These studies reported several patterns of mixed methods use which illustrated the unique insights that researchers can gain by using this approach. We identified several ways that authors could more clearly report the justification for using a mixed methods approach, the description of the design used, and the evidence of integration of the quantitative and qualitative components.

CONCLUSION

We make recommendations for improving the reporting quality of mixed methods intervention studies in the field of emotional and behavioral disorders.

How to embed qualitative research in trials: insights from the feasibility study of the SAFER trial programme

Qualitative research can enhance the design, conduct and interpretation of trials. Despite this, few trials incorporate qualitative methods, and those that do may not realise their full potential. In this commentary, we highlight how qualitative research can contribute to the design, conduct and day-to-day running of a trial, outlining the working arrangements and relationships that facilitate these contributions. In doing so, we draw on (i) existing frameworks on the role of qualitative research alongside trials and (ii) our experience of integrated qualitative research conducted as part of the feasibility study of the SAFER trial (Screening for Atrial Fibrillation with ECG to Reduce stroke), a cluster randomised controlled trial of screening people aged 70 and above for atrial fibrillation in primary care in England. The activities and presence of the qualitative team contributed to important changes in the design, conduct and day-to-day running of the SAFER feasibility study, and the subsequent main trial, informing diverse decisions concerning trial documentation, trial delivery, timing and content of measures and the information given to participating patients and practices. These included asking practices to give screening results to all participants and not just to 'screen positive' participants, and greater recognition of the contribution of practice reception staff to trial delivery. These changes were facilitated by a 'one research team' approach that underpinned all formal and informal working processes from the outset and maximised the value of both qualitative and trial coordination expertise. The challenging problems facing health services require a combination of research methods and data types. Our experience and the literature show that the benefits of embedding qualitative research in trials are more likely to be realised if attention is given to both structural factors and relationships from the outset. These include sustained and sufficient funding for qualitative research, embedding qualitative research fully within the trial programme, providing shared infrastructure and resources and committing to relationships based on mutual recognition of and respect for the value of different methods and perspectives. We outline key learning for the planning of future trials.Trial registration: Screening for atrial fibrillation with ECG to reduce stroke ISRCTN16939438 (feasibility study); Screening for atrial fibrillation with ECG to reduce stroke - a randomised controlled trial ISRCTN72104369 .

"Your double-blind RCT needs feminism": an argument for engaging critical theory in quantitative rehabilitation research

PURPOSE

Rehabilitation science has, for years, endorsed a connection between quantitative research and the philosophical assumptions of positivism. These assumptions can limit the scope of rehabilitation research, particularly in relation to matters of equity, diversity, and inclusivity. As our field moves toward a greater focus on inclusivity in research design and patient-centred care, it is imperative that we reconsider the theoretical foundations of rehabilitation research and practice.

METHODS

We provide an analysis of positivism on equity, diversity, and inclusivity within quantitative rehabilitation research, using the Participant Intervention Comparison Outcome (PICO) model to provide structure for the resultant discussion and recommendations.

RESULTS

Our analysis reveals that there are significant limitations and ethical concerns to engaging in positivism as the primary paradigm for quantitative rehabilitation research. We argue that decoupling of positivism and quantitative research methods may be warranted.

CONCLUSIONS

Equitable and inclusive rehabilitation research requires the researcher to consider variables which are neglected in the positivist paradigm. We argue that critical theory can equip researchers with a lens to better address injustices within rehabilitation research. We provide a series of recommendations for researchers to engage critical theory at each stage of the PICO model of clinical trials.IMPLICATIONS FOR REHABILITATIONCommon assumptions in quantitative rehabilitation research (i.e., positivism) can limit the utility of research findings to rehabilitation patients.Equitable, diverse, and inclusive participant samples in research better reflect the diversity of real world rehabilitation patients, helping us better serve these populations.Critical theory can help researchers and clinicians identify and avoid interventions that may cause harm to rehabilitation patients.Research and practice that prioritize concepts of "normalcy" (i.e., "normal gait," "normal behaviours") may perpetuate negative concepts of disability and further marginalize the individuals that our interventions aim to serve.

Investigation of Barriers and Facilitators to Medication Adherence in Patients With Type 2 Diabetes Across Different Health Literacy Levels: An Explanatory Sequential Mixed Methods Study

Type 2 diabetes (T2D) incurs tremendous healthcare costs associated with various complications due to poor blood sugar control. Medication adherence, which is correlated with patients’ health literacy, should be consistently practiced to achieve optimal control of blood sugar. A comprehensive understanding of specific communication and psychosocial factors related to medication-taking behaviors across different levels of health literacy among people with T2D will guide the development of effective interventions and strategies to enhance medication adherence. To understand barriers and facilitators to medication adherence in people with T2D across different health literacy levels, the Health Literacy Pathway Model was used to identify the psychosocial and communication factors that may influence medication adherence. This mixed methods study used an explanatory sequential design, including a quantitative survey followed by qualitative semi-structured interviews. Two hundred and five participants completed the survey questionnaire, and 23 participants completed semi-structured interviews. Confirmed by quantitative and qualitative data, having stronger self-efficacy and fewer concerns about medications, as well as experiencing fewer perceived barriers to medication-taking, are necessary for better medication adherence among those with low adherence. Our findings will be useful to tailor interventions for diabetes care through addressing concerns among low-adherent patients with low health literacy and emphasizing self-efficacy and perceived barriers to medication adherence among all low-adherent patients with T2D.

BreathEase: rationale, design and recruitment of a randomised trial and embedded mixed-methods study of a multiprofessional breathlessness service in early palliative care

BACKGROUND

The Munich Breathlessness Service has adapted novel support services to the German context, to reduce burden in patients and carers from breathlessness in advanced disease. It has been evaluated in a pragmatic fast-track randomised controlled trial (BreathEase; NCT02622412) with embedded qualitative interviews and postal survey. The aim of this article is to describe the intervention model and study design, analyse recruitment to the trial and compare sample characteristics with other studies in the field.

METHODS

Analysis of recruitment pathways and enrolment, sociodemographic and clinical characteristics of participants and carers.

RESULTS

Out of 439 people screened, 253 (58%) were offered enrolment and 183 (42%) participated. n=97 (70%) carers participated. 186 (42%) people did not qualify for inclusion, mostly because breathlessness could not be attributed to an underlying disease. All participants were self-referring; 60% through media sources. Eligibility and willingness to participate were associated to social networks and illness-related activities as recruitment routes. Mean age of participants was 71 years (51% women), with COPD (63%), chronic heart failure (8%), interstitial lung disease (9%), pulmonary hypertension (6%) and cancer (7%) as underlying conditions. Postal survey response rate was 89%. Qualitative interviews were conducted with 16 patients and nine carers.

CONCLUSION

The BreathEase study has a larger and more heterogeneous sample compared to other trials. The self-referral-based and prolonged recruitment drawing on media sources approximates real-world conditions of early palliative care. Integrating qualitative and quantitative components will allow a better understanding and interpretation of the results of the main effectiveness study.

A Pluralistic Perspective on Research in Psychotherapy: Harnessing Passion, Difference and Dialogue to Promote Justice and Relevance

The adoption of a pluralistic perspective on research design, processes of data collection and analysis and dissemination of findings, has the potential to enable psychotherapy research to make a more effective contribution to building a just society. A review of the key features of the concept of pluralism is followed by a historical analysis of the ways in which research in counselling, psychotherapy and related disciplines has moved in the direction of a pluralistic position around knowledge creation. Core principles of a pluralistic approach to research are identified and explored in the context of a critical case study of contemporary research into psychotherapy for depression, examples of pluralistically oriented research practices, and analysis of a pluralistic conceptualisation of the nature of evidence. Implications of a pluralistic perspective for research training and practice are discussed. Pluralistic inquiry that emphasises dialogue, collaboration, epistemic justice and the co-existence of multiple truths, creates opportunities for individuals, families and communities from a wide range of backgrounds to co-produce knowledge in ways that support their capacities for active citizenship and involvement in open democratic decision-making. To fulfil these possibilities, it is necessary for psychotherapy research to be oriented towards social goals that are sufficiently relevant to both researchers and co-participants to harness their passion and work together for a common good.

Challenging procedures used in systematic reviews by promoting a case-based approach to the analysis of qualitative methods in nursing trials

This methodological discussion invites critical reflection about the procedures used to analyze the contribution of qualitative and mixed methods research to nursing trials by mounting an argument that these should rest on multiple publications produced about a project, rather than a single article. We illustrate the value-added of this approach with findings from a qualitative, cross-case analysis of three critical case exemplars from nursing researchers that each used a qualitative approach with a mixed method phase. The holistic lens afforded by a case-based approach informs nursing inquiry by documenting that the critical case exemplars presented evidence of (a) a sustained commitment of resources and expertise for the qualitative methods that extended across more than one phase of the trial, (b) the impact of the qualitative methods on the trial or its aftermath, (c) deploying a theoretical or conceptual framework for a variety of purposes, and (d) integrating qualitative and quantitative data for purposes of extending explanatory power. Findings challenge the practice of linking purposes served by qualitative and mixed methods to a single trial phase.

Quantitative and Qualitative Strategies to Strengthen Internal Validity in Randomized Trials

Although the randomized controlled trial (RCT) is the most reliable design to infer causality, evidence suggests that it is vulnerable to biases that weaken internal validity. In this paper, we review factors that introduce biases in RCTs and we propose quantitative and qualitative strategies for colleting relevant data to strengthen internal validity. The factors are related to participants' reactions to randomization, attrition, treatment perceptions, and implementation of the intervention. The way in which these factors operate is explained and pertinent empirical evidence is synthesized. Quantitative and qualitative strategies are described. Researchers can plan to assess these factors and examine their influence, providing evidence of what actually contributed to the interventions' causal impact.

Water Scarcity and Water Quality: Identifying Potential Unintended Harms and Mitigation Strategies in the Implementation of the Biosand Filter in Rural Tanzania

Bottom-up public health interventions are needed which are built on an understanding of community perspectives. Project SHINE is a community-based participatory action research intervention focused on developing sustainable water, sanitation, and hygiene strategies with Maasai pastoralists in Tanzania. The aim of the study is to understand perceptions related to water quality and scarcity as well as to assess the potential of the Biosand Filter as a low-cost, low-tech water treatment option. To avoid unintended harms, the community was engaged in identifying potential harms and mitigation strategies prior to the implementation of the filter.Two in-depth interviews and two group discussions were analyzed using thematic content analysis, while three think tanks were analyzed using directed content analysis. The findings highlight a range of concerns regarding water scarcity and quality. The think tank approach was an effective means of engaging the community in identifying potential unintended harms across four dimensions: the physical, psychosocial, economic, and cultural contexts. In addition, two external themes emerged as salient: political harm and harm by omission.

Reflexive Intervention Development: Using Qualitative Research to Inform the Development of an Intervention for Women With Metastatic Breast Cancer

There is growing consensus around the limited attention given to documenting the process of intervention development, specifically the role of qualitative research. In this article, we seek to describe a missing piece of this process: how qualitative research, and related methodologies and theories, informs intervention development. We use our research as a case study of "reflexive intervention development." We begin by describing our interview study, consisting of 23 in-depth interviews with women diagnosed with metastatic breast cancer, and go on to detail our methodological framework and research team. We then explain how this interview study directly informed our development of the intervention materials, allowing us to attend carefully to language and its potential implications for women. We conclude by inviting researchers to reflect on the knowledge production process that is inherent in intervention development to consider not only their role in this process but also the role of qualitative research.

Finding the Way Forward: The Lived Experience of People With Stroke After Participation in a Complex Psychosocial Intervention

Stroke patients' well-being is threatened after stroke. A psychosocial intervention was developed for Norwegian stroke patients living in the community. Eight individual sessions between people with stroke and a trained health care professional were conducted 1 to 6 months post-stroke with one group of participants and 6 to 12 months post-stroke with another group. Subsequently, 19 of these stroke patients were interviewed to gain an in-depth understanding of their lived experience of the influence of the intervention on their adjustment process. Interview texts were analyzed using Ricoeur's interpretation theory. Two participants did not personally find the intervention useful. The remaining participants greatly appreciated dialogues with the empathetic intervention personnel, feeling free to discuss their fears and worries. The intervention raised these participants' awareness of their needs and resources. They were guided to resume their everyday life and adopt a future-oriented attitude. The intervention facilitated their meaning-making endeavors and post-stroke adjustment.

Develop Your Case! How Controversial Cases, Subcases, and Moderated Cases Can Guide You Through Mixed Methods Data Analysis

In this article, we present mixed methods data analysis in educational research as a process of case development. We define a case as a theoretical construct that is developed through iterative and spiraling cycles of interaction between ideas and evidence. On a larger scale, cases develop over a period of several years or even decades, involving many studies. But cases also develop within a much smaller timescale, within studies. Development of cases within mixed methods studies is the theme of this article. We define the purpose for any mixed methods study as to acquire detailed insight into the case, subcases, and the way the subcases are moderated. Developing a case starts with identifying a phenomenon that will be the object of research. A phenomenon can be investigated empirically once researchers are able to identify specific contexts, localized in time and space, in which the phenomenon occurs. At that point, an underdeveloped case has come into being, and the specific contexts in which the case occurs are called instantiations of the case. Connected to each case are claims, statements about the case that are used to describe the case more precisely and to distinguish cases from non-cases. Developing these claims is the aim of the analysis processes. Case development includes three different research processes-namely, resolving a controversial case, developing subcases, and developing a moderated case. Case development typically occurs in this order; however, each of these processes can but do not need to be present. When cases develop, they typically become controversial for some time. Some research studies support a specific claim, while other research studies refute this claim. Next to claims that apply to all instantiations of a case, claims may be developed that apply to only some of the case's instantiations. In that case, claims are used to distinguish subcases. A moderated case is developed when researchers come to understand under which circumstances their claim does and does not apply, which leads to their subcases. This is called "moderation" of their claim.

Evaluation of a Mobile Phone-Based Intervention to Increase Parents' Knowledge About the Measles-Mumps-Rubella Vaccination and Their Psychological Empowerment: Mixed-Method Approach

BACKGROUND

There is mixed evidence on the effectiveness of vaccination-related interventions. A major limitation of most intervention studies is that they do not apply randomized controlled trials (RCTs), the method that, over the last 2 decades, has increasingly been considered as the only method to provide proof of the effectiveness of an intervention and, consequently, as the most important instrument in deciding whether to adopt an intervention or not. This study, however, holds that methods other than RCTs also can produce meaningful results.

OBJECTIVE

The aim of this study was to evaluate 2 mobile phone-based interventions aimed at increasing parents' knowledge of the measles-mumps-rubella (MMR) vaccination (through elements of gamification) and their psychological empowerment (through the use of narratives), respectively. The 2 interventions were part of an RCT.

METHODS

We conducted 2 studies with the RCT participants: a Web-based survey aimed at assessing their rating of the tool regarding a number of qualities such as usability and usefulness (N=140), and qualitative telephonic interviews to explore participants' experiences with the app (N=60).

RESULTS

The results of the survey showed that participants receiving the knowledge intervention (alone or together with the empowerment intervention) liked the app significantly better compared with the group that only received the empowerment intervention (F_2,137=15.335; P<.001). Parents who were exposed to the empowerment intervention complained that they did not receive useful information but were only invited to make an informed, autonomous MMR vaccination decision.

CONCLUSIONS

The results suggest that efforts to empower patients should always be accompanied by the provision of factual information. Using a narrative format that promotes parents' identification can be an appropriate strategy, but it should be employed together with the presentation of more points of views and notions regarding, for instance, the risks and benefits of the vaccination at the same time.
