Application of behavioural theories, models, and frameworks in pharmacy practice research based on published evidence: a scoping review

BACKGROUND

Pharmacy practice research often focuses on the design, implementation and evaluation of pharmacy services and interventions. The use of behavioural theory in intervention research allows understanding of interventions' mechanisms of action and are more likely to result in effective and sustained interventions.

AIM

To collate, summarise and categorise the reported behavioural frameworks, models and theories used in pharmacy practice research.

METHOD

PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science and EBSCO (CINAHL PLUS, British Education index, ERIC) were systematically searched to capture all pharmacy practice articles that had reported the use of behavioural frameworks, theories, or models since inception of the database. Results were filtered to include articles published in English in pharmacy practice journals. Full-text screening and data extraction were independently performed by two reviewers. A narrative synthesis of the data was adopted. Studies were reviewed for alignment to the UK Medical Research Council (MRC) framework to identify in which phase(s) of the research that the theory/model/framework had been employed.

RESULTS

Fifty articles met the inclusion criteria; a trend indicating an increasing frequency of behavioural theory/frameworks/models within pharmacy practice research was identified; the most frequently reported were Theory of Planned Behaviour and Theoretical Domains Framework. Few studies provided explicit and comprehensive justification for adopting a specific theory/model/framework and description of how it underpinned the research was lacking. The majority were investigations exploring determinants of behaviours, or facilitators and barriers to implementing or delivering a wide range of pharmacy services and initiatives within a variety of clinical settings (aligned to Phase 1 UK MRC framework).

CONCLUSION

This review serves as a useful resource for future researchers to inform their investigations. Greater emphasis to adopt a systematic approach in the reporting of the use of behavioural theories/models/frameworks will benefit pharmacy practice research and will support researchers in utilizing behavioural theories/models/framework in aspects of pharmacy practice research beyond intervention development.

Usability and feasibility of PreventS-MD web app for stroke prevention

BACKGROUND

Most strokes and cardiovascular diseases (CVDs) are potentially preventable if their risk factors are identified and well controlled. Digital platforms, such as the PreventS-MD web app (PreventS-MD) may aid health care professionals (HCPs) in assessing and managing risk factors and promoting lifestyle changes for their patients.

METHODS

This is a mixed-methods cross-sectional two-phase survey using a largely positivist (quantitative and qualitative) framework. During Phase 1, a prototype of PreventS-MD was tested internationally by 59 of 69 consenting HCPs of different backgrounds, age, sex, working experience, and specialties using hypothetical data. Collected comments/suggestions from the study HCPs in Phase 1 were reviewed and implemented. In Phase 2, a near-final version of PreventS-MD was developed and tested by 58 of 72 consenting HCPs using both hypothetical and real patient (n = 10) data. Qualitative semi-structured interviews with real patients (n = 10) were conducted, and 1 month adherence to the preventive recommendations was assessed by self-reporting. The four System Usability Scale (SUS) groups of scores (0-50 unacceptable; 51-68 poor; 68-80.3 good; >80.3 excellent) were used to determine usability of PreventS-MD.

FINDINGS

Ninety-nine HCPs from 27 countries (45% from low- to middle-income countries) participated in the study, and out of them, 10 HCPs were involved in the development of PreventS before the study, and therefore were not involved in the survey. Of the remaining 89 HCPs, 69 consented to the first phase of the survey, and 59 of them completed the first phase of the survey (response rate 86%), and 58 completed the second phase of the survey (response rate 84%). The SUS scores supported good usability of the prototype (mean score = 80.2; 95% CI [77.0-84.0]) and excellent usability of the final version of PreventS-MD (mean score = 81.7; 95% CI [79.1-84.3]) in the field. Scores were not affected by the age, sex, working experience, or specialty of the HCPs. One-month follow-up of the patients confirmed the high level of satisfaction/acceptability of PreventS-MD and (100%) adherence to the recommendations.

INTERPRETATION

The PreventS-MD web app has a high level of usability, feasibility, and satisfaction by HCPs and individuals at risk of stroke/CVD. Individuals at risk of stroke/CVD demonstrated a high level of confidence and motivation in following and adhering to preventive recommendations generated by PreventS-MD.

Translating evidence-based knowledge objects into practice

This paper aims to show how organizational translation theories and models may supplement implementation science with a new process perspective on how knowledge objects such as Cochrane reviews, clinical guidelines and reference programs are implemented in practice in healthcare organizations. They build on Bruno Latour's idea about translation that states that the spread in time and space of anything-including knowledge objects-is in the hands of people and that each of these people may act in many different ways, letting the token drop, modifying it, deflecting it, betraying it, adding to it, or appropriating it. Implementation science theories, models and frameworks often try to identify general aspects of processes and variables that influence implementation processes. In contrast, translation theories and models build on a process view that uses the sequence of events, activities and choices by translators situated in time as well as in space to explain how outcomes of translation/implementation processes came about. The paper develops some implementation relevant propositions about translation of knowledge objects in healthcare organizations that may inform further research. Moreover, it discusses how organizational translation studies and implementation science may supplement each other.

"Family Is the Beginning but Not the End": Intergenerational LGBTQ Chosen Family, Social Support, and Health in a Vietnamese American Community Organization

Homophobia and anti-LGBTQ (Lesbian, Gay, Bisexual, Transgender, and Queer) discrimination within ethnic communities can negatively impact the health of LGBTQ people. The formation of chosen families has been a source of social support that may have health benefits for LGBTQ people. This ethnographic study explores how participation in a LGBTQ Vietnamese American community organization reveals the salience of chosen family in informing individual members' perceptions of their health and well-being. Fifteen members were interviewed and over 30 were included in a 6-month participant-observation period. Three themes emerged: 1) queering family and kinship, 2) Vietnamese motherhood and the social reproduction of the family, 3) social ties and community connectedness as relational dimensions of health. Findings suggest that specific ethnic social support via chosen family formations for LGBTQ Vietnamese Americans can shape individuals' sense of self, sense of belonging, purpose in life, and consequently perceptions of well-being.

Repeated measures of implementation variables

It is commonly acknowledged that implementation work is long-term and contextual in nature and often takes years to accomplish. Repeated measures are needed to study the trajectory of implementation variables over time. To be useful in typical practice settings, measures that are relevant, sensitive, consequential, and practical are needed to inform planning and action. If implementation independent variables and implementation dependent variables are to contribute to a science of implementation, then measures that meet these criteria must be established. This exploratory review was undertaken to "see what is being done" to evaluate implementation variables and processes repeatedly in situations where achieving outcomes was the goal (i.e., more likely to be consequential). No judgement was made about the adequacy of the measure (e.g., psychometric properties) in the review. The search process resulted in 32 articles that met the criteria for a repeated measure of an implementation variable. 23 different implementation variables were the subject of repeated measures. The broad spectrum of implementation variables identified in the review included innovation fidelity, sustainability, organization change, and scaling along with training, implementation teams, and implementation fidelity. Given the long-term complexities involved in providing implementation supports to achieve the full and effective use of innovations, repeated measurements of relevant variables are needed to promote a more complete understanding of implementation processes and outcomes. Longitudinal studies employing repeated measures that are relevant, sensitive, consequential, and practical should become common if the complexities involved in implementation are to be understood.

Systematic Review of Health Promotion Frameworks Focused on Health in the Postpartum Period

OBJECTIVE

To systematically review the scope and development of frameworks to promote health during the postpartum period.

DATA SOURCES

We searched PubMed, CINAHL, and American Psychological Association PsycInfo during May 2021.

STUDY SELECTION

We included English-language, peer-reviewed articles focused on frameworks for health promotion in the postpartum period. We placed no time limit on publication date. Our search resulted in 2,355 articles after we removed duplicates. After excluding articles based on titles and abstracts, we conducted full-text reviews of 23 articles. Three articles met inclusion criteria and addressed the following frameworks: Integrated Perinatal Health Framework, Perinatal Maternal Health Promotion Model, and Maternal Self-Care Framework.

DATA EXTRACTION

We extracted data into analytic tables that included categories for the scope, such as time frame, and criteria for the level of development of the frameworks, including the origins, concept definitions and theoretical linkages among concepts, and evidence of application in research or practice.

DATA SYNTHESIS

The three frameworks described in the articles included in our review covered various periods, including the reproductive life span, the first year after birth, and the first 6 weeks after birth. Overall, the frameworks were comprehensive. Most key concepts in the frameworks were defined, and some degree of relationships linking concepts was specified. Empirical referents were provided for most but not all concepts in the frameworks. Developers of the three frameworks elaborated on application in practice or health services, but only the developers of the Maternal Self-Care Framework indicated how their framework might be used in research. The Integrated Perinatal Health Framework and Maternal Self-Care Framework were partially derived from existing general theories; the methods used to develop the Perinatal Maternal Health Promotion Model were less clear.

CONCLUSION

The frameworks met most criteria and together provided a comprehensive strategy for health promotion during the postpartum period. Elaboration of the frameworks for application in research is needed.

Expanding the conversation: A Person-centred Communication Enhancement Model

The intricacy and impact of human communication has long captured the attention of philosophers, scholars and practitioners. Within the realm of care and service provision, efforts to maximize outcomes through optimal person-provider communication have drawn research and clinical focus to this area for several decades. With the dawning of the person-centred care movement within healthcare, and in particular long-term care home and dementia care settings, improvement in care providers’ use of person-centred communication strategies and enhancement of relationships between residents, their families and care providers are desired outcomes. Thus, several person-centred care and communication theoretical perspectives have been employed to ground study in this field. However, a comprehensive theoretical position to underpin person-centred communication in dementia and older adult research does not exist to our knowledge. To offer expansion to the theoretical work in this emerging field, a Person-Centred Communication Enhancement Model for long-term care and dementia care is proposed, as well as rationale for its development. This discussion will also provide an overview and critique of the extant philosophies, theories, frameworks and models that have been utilized in the study of person-centred communication within the context of long-term care and dementia care.

A scoping review of de-implementation frameworks and models

BACKGROUND

Reduction or elimination of inappropriate, ineffective, or potentially harmful healthcare services and public health programs can help to ensure limited resources are used effectively. Frameworks and models (FM) are valuable tools in conceptualizing and guiding the study of de-implementation. This scoping review sought to identify and characterize FM that can be used to study de-implementation as a phenomenon and identify gaps in the literature to inform future model development and application for research.

METHODS

We searched nine databases and eleven journals from a broad array of disciplines (e.g., healthcare, public health, public policy) for de-implementation studies published between 1990 and June 2020. Two raters independently screened titles and abstracts, and then a pair of raters screened all full text records. We extracted information related to setting, discipline, study design, methodology, and FM characteristics from included studies.

RESULTS

The final search yielded 1860 records, from which we screened 126 full text records. We extracted data from 27 articles containing 27 unique FM. Most FM (n = 21) were applicable to two or more levels of the Socio-Ecological Framework, and most commonly assessed constructs were at the organization level (n = 18). Most FM (n = 18) depicted a linear relationship between constructs, few depicted a more complex structure, such as a nested or cyclical relationship. Thirteen studies applied FM in empirical investigations of de-implementation, while 14 articles were commentary or review papers that included FM.

CONCLUSION

De-implementation is a process studied in a broad array of disciplines, yet implementation science has thus far been limited in the integration of learnings from other fields. This review offers an overview of visual representations of FM that implementation researchers and practitioners can use to inform their work. Additional work is needed to test and refine existing FM and to determine the extent to which FM developed in one setting or for a particular topic can be applied to other contexts. Given the extensive availability of FM in implementation science, we suggest researchers build from existing FM rather than recreating novel FM.

Theoretical approaches to process evaluations of complex interventions in health care: a systematic scoping review protocol

BACKGROUND

Complex interventions in health care are characterized by multiple interacting components as well as by numerous nonlinear interactions with the social systems within which they are being implemented. The process of developing, evaluating and implementing complex interventions is therefore challenging. Established guidance such as the MRC (Medical Research Council) framework for developing and evaluating complex interventions refers to process evaluations as an integral part of the development of complex evidence-based interventions. Even though the need for process evaluations is recognized, the realization of such approaches is challenging because methodological instruction is sparse, and the phenomenon of interest is complex. A number of theoretical approaches indicating how to conduct process evaluations of complex interventions in health care exist, but a systematic and comprehensive overview of these is missing. Thus, the objective of the systematic scoping review described herein is to provide an overview and analysis of theoretical approaches suitable for the planning and conducting of process evaluations.

METHODS

The design and conduct of this review will follow the procedures of a systematic scoping review. The search strategy will be developed following the BeHEMoTh (Behaviour of interest; Health context; Exclusions; Models or Theories) template which has been conceptualized for structured reviews of theory. The systematic search of the MEDLINE (via PubMed), CINAHL (via EBSCO) and PsycInfo (via EBSCO) electronic databases will be complemented by "hand searching" techniques. Study selection, data extraction, and data analysis will be performed by tandems of two researchers independently of each other. Divergent decisions and judgements between the two researchers will be discussed by the whole review team.

DISCUSSION

The findings from this scoping review will provide an overview and comparison of theoretical approaches suitable for process evaluations of complex interventions in health care. The review results will support researchers in choosing the theoretical approach that best fits the respective focus of their process evaluation study.

Screening for Yellow Flags in Orthopaedic Physical Therapy: A Clinical Framework

BACKGROUND

Psychological factors influence or are associated with physical function, pain, and health care costs among individuals with musculoskeletal pain conditions. Recent clinical practice guidelines recommend screening for psychological factors (also referred to as "yellow flags") in physical therapy practice to help understand prognosis and inform shared decision making for treatment.

CLINICAL QUESTION

Despite the urgings of clinical practice guidelines and evidence of the influence of psychological factors on clinical outcomes, screening for yellow flags is uncommon in clinical practice. Clinicians may feel uncertain about how to integrate screening tools into clinical practice, and how screening results might inform decision making and care coordination.

KEY RESULTS

We outline a 3-step framework for routine yellow flag screening in physical therapy practice: (1) establish a standard first-line screening instrument and process, (2) interpret the results to inform shared decision making, and (3) monitor treatment progress. Four case examples illustrate how yellow flag screening can help clinicians and patients decide whether the patient might benefit most from standard physical therapy, psychologically informed physical therapy, psychologically informed physical therapy with referral to another health care provider, or immediate referral.

CLINICAL APPLICATION

Consider incorporating a standard yellow flag screening process into usual musculoskeletal health care. We present a framework to guide yellow flag screening in practice (1) to help inform treatment pathway selection and (2) to enhance interdisciplinary communication.

The public health community's use of social media for policy advocacy: a scoping review and suggestions to advance the field

OBJECTIVES

This study aimed to investigate the extent and key characteristics of academic research and scholarship on the public health community's use of social media for policy advocacy purposes. This will enable an evaluation of extant research and provide insight into directions for future research.

STUDY DESIGN

This study was a scoping review of academic literature.

METHODS

A scoping review of academic literature published between 1 January 2011 and 31 December 2020 was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. Boolean searches were conducted using a university library platform, which included databases, such as EBSCO host, Informit, Scopus, and ScienceDirect. Data were extracted using an a priori code frame, and publication, content, and disciplinary characteristics were analysed. The results of coding and screening comparison checks were within acceptable limits.

RESULTS

In total, 2672 works from around the world were identified and screened for inclusion. Twenty-two English language articles were included in the final analysis. The public health community's use of social media for policy advocacy purposes has largely been approached from a health perspective, despite research and scholarship about social media in communication and policy disciplines (among others). Reported research aims or questions emphasised functional rather than theoretical contributions. Most analysed works used empirical or case study-based methods and were produced by authors in Western geographies. Among the health issues discussed, tobacco and tobacco control were discussed most frequently. While recognising issues with social media, most publications framed social media as more of an opportunity than a problem.

CONCLUSIONS

The public health community's use of social media for policy advocacy purposes is an emerging field. There is considerable potential to expand scholarship and research in this field internationally, especially by integrating transdisciplinary knowledge and perspectives and by applying social media to foster policy change around identified global health challenges. Greater representation of authors from institutions in the Global South is also encouraged, as are applied and theoretical contributions.

A Model for the Taxonomy of Research Studies: A Practical Guide to Knowledge Production and Knowledge Management

Context: Due to the increasing research information, knowledge production, development of information technology, and its impact on access to knowledge, the taxonomy of knowledge and information is necessary to manage and use them in the development of science. Evidence Acquisition: The purpose of this study was to provide a complete model that could achieve the objectives of taxonomy in research. For this purpose, after a critical review of existing taxonomies, criteria were developed based on which a complete and practical taxonomy was presented. After reviewing and analyzing different categorizations of research in different fields of medicine, social sciences, and education, research designs were divided into explicative research, psychometric research, descriptive research, exploratory research, explanatory research, theory research, translational research, synthetic research, prescriptive research, implementation research, and evaluative research. Conclusions: In the next step, the relationship between them was determined based on their cognitive position and their position in the development of knowledge.

The principles of Nurturing Care promote human capital and mitigate adversities from preconception through adolescence

A comprehensive evidence-based framework is needed to guide policies and programmes that enable children and adolescents to accrue the human capital required to meet the Sustainable Development Goals (SDGs). This paper proposes a comprehensive, multisectoral, multilevel life-course conceptualisation of human capital development by building on the Nurturing Care Framework (NCF), originally developed for the foundational period of growth and development through the age 3 years. Nurturing care (NC) comprises stable environments that promote children's health and nutrition, protect from threats, and provide opportunities for learning and responsive, emotionally supportive and developmentally enriching relationships. NC is fostered by families, communities, services, national policies and beyond. The principles apply across the life course, endorse equity and human rights, and promote long-term human capital. This paper presents an evidence-based argument for the extension of the NCF from preconception through adolescence (0-20 years), organised into six developmental periods: preconception/prenatal, newborn/birth, infancy/toddlerhood, preschool, middle childhood and adolescence. The proposed framework advances human capital within each developmental period by promoting resilience and adaptive developmental trajectories while mitigating negative consequences of adversities.Attaining the SDGs depends on strengthening human capital formation, extending throughout childhood and adolescence and supported by NC. Embedded in enabling laws, policies and services, the dynamic NCF components can mitigate adversities, enhance resilience and promote the well-being of marginalised groups. The life-course extension of the NCF is strategically positioned to enhance human capital, to attain the SDGs and to ensure that children or adolescents are not left behind in reaching their developmental potential.

Reconnecting to others: grounded theory of social functioning following age-related hearing loss

Age-related hearing loss (ARHL) is common and a known risk factor for social disengagement in later life. This study explored social functioning following a diagnosis of ARHL. Using a constructivist grounded theory approach we developed an interview schedule to advance a grounded theory from data collected from six older adults who used either hearing aids or cochlear implants. Interview questions concerned social functioning as well as focusing on their perspective of the impact of ARHL on cognitive functioning. We describe a grounded theory conceived as ‘Reconnecting to Others’. This theory posits that participants faced social challenges in relation to their ARHL, and resolved these challenges partly through the use of hearing aids and cochlear implantation. The theory also emphasises the importance of help from other hearing aid users for new users, and corroborates prior findings about strategies older adults with ARHL use to cope with their hearing impairment in various social situations. Once hearing aids and cochlear implants are used and adapted to with the help of peers, participants completed their journey by helping others who had received diagnoses of ARHL. Additionally, participants spoke of the pleasure of hearing again. Interestingly, no participant felt that their ARHL had impacted their cognitive functioning. Our theory provides a basis for explaining existing quantitative findings as well as creating new hypotheses for future testing.

Unpacking 'the cloud': a framework for implementing public health approaches to palliative care

Designing and implementing population-based systems of care that address the social determinants of health, take action on multiple levels, and are guided by evidence-based principles is a pressing priority, and an international challenge. Aging persons are a priority demographic whose health needs span physical, psychosocial and existential care domains, increase in the last year of life, are often poorly coordinated and therefore remain unmet. Compassionate communities (CCs) are an example of a public health approach that fully addresses the holistic healthcare needs of those who are aging and nearing end of life. The sharing of resources, tools, and innovations among implementers of CCs is occurring globally. Although this can increase impact, it also generates complexity that can complicate robust evaluation. When initiating population health level projects, it is important to clearly define and organize concepts and processes that are proposed to influence the health outcomes. The Health Impact Change Model (HICM) was developed to unpack the complexities associated with the implementation and evaluation of a Canadian CC intervention. The HICM offers utility for citizens, leaders and decision-makers who are engaged in the implementation of population health level strategies or other social approaches to care, such as compassionate cities and age or dementia-friendly communities. The HICM's concepts can be adapted to address a community's healthcare context, needs, and goals for change. We share examples of how the model's major concepts have been applied in the development, evaluation and spread of a complex CC approach.

The Transition From Medical Student to Resident: A Qualitative Study of New Residents' Perspectives

PURPOSE

To understand the learner's perspective on the transition from medical school to residency and to develop a conceptual model for how learners experience the transition from student to resident.

METHOD

This prospective qualitative study explored the experience of first-year residents using semistructured, one-on-one telephone interviews. Ten first-year residents who participated in the Transition to Residency elective as fourth-year students at the New York University Grossman School of Medicine in April 2018 participated from December 2018 to April 2019. Using a 3-phase coding process and grounded theory methodology, the authors identified categories, which they organized into broader themes across interview transcripts and used to develop a conceptual model.

RESULTS

From the perspective of new residents, developing professional identity is the core construct of the transition experience. The residents focused on individual aspects of the experience-professional identity, self-awareness, professional growth, approach to learning, and personal balance-and external aspects-context of learning, professional relationships, and challenges in the context of their new role. Across these 8 categories, 5 broader themes emerged to describe an abrupt change in educational environment, an immersive experience of learning as a resident, ambivalence and tensions around the new role, navigation of professional relationships, and balance and integration of working in medicine with personal lives and goals. A conceptual model illustrates this phenomenon as a cell where professional identity and growth (the nucleus) is surrounded by interactions with patients and other members of the medical team (in the cytoplasm) that create a substrate for learning and development.

CONCLUSIONS

This study suggests that being immersed in the residency experience is how medical students transition to resident physicians. Educational interventions that allow learners to acclimate to the experience of being a doctor through gradual exposure to authentic interactions have the potential to bridge the abrupt transition.

Moving Upstream: The Effect of Tobacco Clean Air Restrictions on Educational Inequalities in Smoking Among Young Adults

Education affords a range of direct and indirect benefits that promote longer and healthier lives and stratify health lifestyles. We use tobacco clean air policies to examine whether policies that apply universally-interventions that bypass individuals' unequal access and ability to employ flexible resources to avoid health hazards-have an effect on educational inequalities in health behaviors. We test theoretically informed but competing hypotheses that these policies either amplify or attenuate the association between education and smoking behavior. Our results provide evidence that interventions that move upstream to apply universally regardless of individual educational attainment-here, tobacco clean air policies-are particularly effective among young adults with the lowest levels of parental or individual educational attainment. These findings provide important evidence that upstream approaches may disrupt persistent educational inequalities in health behaviors. In doing so, they provide opportunities to intervene on behaviors in early adulthood that contribute to disparities in morbidity and mortality later in the life course. These findings also help assuage concerns that tobacco clean air policies increase educational inequalities in smoking by stigmatizing those with the fewest resources.

Finding common ground: how the development of theory in public health research can bring us together

Within the past few decades, the academic discipline of public health has taken root in universities around the world. As a young and multidisciplinary field with a dual-research/practice focus and a tradition that emphasises method development, the use of theory in public health research has often been neglected. In this article, we argue that explicit utilisation of theory is crucial to further the development of public health as an academic discipline. By examining three core areas of academic activity at universities—education, research and public outreach—we illustrate the role theory plays in establishing public health as an independent research discipline. We discuss the importance and benefits of including theoretical reasoning in teaching, research articles and communication with non-academic audiences. We also highlight the role of postgraduate students and junior researchers who, thanks to a combination of experience and receptiveness, play an important role in developing public health theory. We believe that a key to a successful process of establishing public health as an academic discipline lies in the development of a transdisciplinary approach to the research subject. This will equip public health researchers with appropriate tools to take on the public health challenges of the future.

Adopting Population Health Frameworks in Physical Therapist Practice, Research, and Education: The Urgency of Now

Chronic, noncommunicable diseases have replaced acute, infectious diseases as the leading causes of global mortality and morbidity. Efforts among physical therapists to address noncommunicable diseases have primarily focused on the promotion of healthy behaviors among individual clients. However, the strongest predictors of chronic disease are tied to where we live, work, learn, and play, our families, and our communities. Population health frameworks can help us better understand the complex interrelations between individuals' health condition and their social and physical environment over time and also inform the development of effective programs and policies that improve the health of individuals and communities. The objectives of this article are to: (1) define population health, prevention, and health promotion; (2) provide a current perspective on the utility of population health frameworks in physical therapy; and (3) identify opportunities for the expanded use of population health frameworks in physical therapist practice, research, and education.

Creation of a new clinical framework - why women choose mastectomy versus breast conserving therapy

BACKGROUND

Clinical medicine has lagged behind other fields in understanding and utilizing frameworks to guide research. In this article, we introduce a new framework to examine why women choose mastectomy versus breast conserving therapy in early stage breast cancer, and highlight the importance of utilizing a conceptual framework to guide clinical research.

METHODS

The framework we present was developed through integrating previous literature, frameworks, theories, models, and the author's past research.

RESULTS

We present a conceptual framework that illustrates the central domains that influence women's choice between mastectomy versus breast conserving therapy. These have been organized into three broad constructs: clinicopathological factors, physician factors, and individual factors with subgroups of sociodemographic, geographic, and individual belief factors. The aim of this framework is to provide a comprehensive basis to describe, examine, and explain the factors that influence women's choice of mastectomy versus breast conserving therapy at the individual level.

CONCLUSION

We have developed a framework with the purpose of helping health care workers and policy makers better understand the multitude of factors that influence a patient's choice of therapy at an individual level. We hope this framework is useful for future scholars to utilize, challenge, and build upon in their own work on decision-making in the setting of breast cancer. For clinician-researchers who have limited experience with frameworks, this paper will highlight the importance of utilizing a conceptual framework to guide future research and provide an example.

Building a middle-range theory of free public healthcare seeking in sub-Saharan Africa: a realist review

Realist reviews are a new form of knowledge synthesis aimed at providing middle-range theories (MRTs) that specify how interventions work, for which populations, and under what circumstances. This approach opens the ‘black box’ of an intervention by showing how it triggers mechanisms in specific contexts to produce outcomes. We conducted a realist review of health user fee exemption policies (UFEPs) in sub-Saharan Africa (SSA). This article presents how we developed both the intervention theory (IT) of UFEPs and a MRT of free public healthcare seeking in SSA, building on Sen’s capability approach. Over the course of this iterative process, we explored theoretical writings on healthcare access, services use, and healthcare seeking behaviour. We also analysed empirical studies on UFEPs and healthcare access in free care contexts. According to the IT, free care at the point of delivery is a resource allowing users to make choices about their use of public healthcare services, choices previously not generally available to them. Users’ ability to choose to seek free care is influenced by structural, local, and individual conversion factors. We tested this IT on 69 empirical studies selected on the basis of their scientific rigor and relevance to the theory. From that analysis, we formulated a MRT on seeking free public healthcare in SSA. It highlights three key mechanisms in users’ choice to seek free public healthcare: trust, risk awareness and acceptability. Contextual elements that influence both users’ ability and choice to seek free care include: availability of and control over resources at the individual level; characteristics of users’ and providers’ communities at the local level; and health system organization, governance and policies at the structural level.

The struggle of translating science into action: Foundational concepts of implementation science

RATIONALE, AIMS, AND OBJECTIVES: "Implementation science," the scientific study of methods translating research findings into practical, useful outcomes, is contested and complex, with unpredictable use of results from routine clinical practice and different levels of continuing assessment of implementable interventions. The authors aim to reveal how implementation science is presented and understood in health services research contexts and clarify the foundational concepts: diffusion, dissemination, implementation, adoption, and sustainability, to progress knowledge in the field.

METHOD

Implementation science models, theories, and frameworks are critiqued, and their value for laying the groundwork from which to implement a study's findings is emphasised. The paper highlights the challenges of turning research findings into practical outcomes that can be successfully implemented and the need for support from change agents, to ensure improvements to health care provision, health systems, and policy. The paper examines how researchers create implementation plans and what needs to be considered for study outputs to lead to sustainable interventions. This aspect needs clear planning, underpinned by appropriate theoretical paradigms that rigorously respond to a study's aims and objectives.

CONCLUSION

Researchers might benefit from a return to first principles in implementation science, whereby applications that result from research endeavours are both effective and readily disseminated and where interventions can be supported by appropriate health care personnel. These should be people specifically identified to promote change in service organisation, delivery, and policy that can be systematically evaluated over time, to ensure high-quality, long-term improvements to patients' health.

Teachable Moments Matter for: An analysis of the use of Pharmacy Curriculum Outcomes Assessment (PCOA) scores within one professional program

Editors Note: The Teachable Moments Matter category of articles is designed to offer readers insight into a methodological issue identified within a companion article. Written in collaboration with one of these authors, these articles provide an opportunity to focus on a challenge experienced by the authors and, in the process, provide one or more perspectives as to how to successfully navigate this issue. Notably, this "issue" is not necessarily a problem (as this first paper in this series demonstrates). The Journal hopes this case-based approach will help highlight an issue nuance in context, something that might get "lost" in the entirety of a full-length article. This article discusses the importance of communicating a conceptual framework (i.e., theory) as a basis for scholarly articles. A specific example in the companion article is use of validity theory. In our community of researchers, we need to better communicate a conceptual framework as a basis to allow others to build on and grow our knowledge in pharmacy education.

Acceptability of healthcare interventions: an overview of reviews and development of a theoretical framework

BACKGROUND

It is increasingly acknowledged that 'acceptability' should be considered when designing, evaluating and implementing healthcare interventions. However, the published literature offers little guidance on how to define or assess acceptability. The purpose of this study was to develop a multi-construct theoretical framework of acceptability of healthcare interventions that can be applied to assess prospective (i.e. anticipated) and retrospective (i.e. experienced) acceptability from the perspective of intervention delivers and recipients.

METHODS

Two methods were used to select the component constructs of acceptability. 1) An overview of reviews was conducted to identify systematic reviews that claim to define, theorise or measure acceptability of healthcare interventions. 2) Principles of inductive and deductive reasoning were applied to theorise the concept of acceptability and develop a theoretical framework. Steps included (1) defining acceptability; (2) describing its properties and scope and (3) identifying component constructs and empirical indicators.

RESULTS

From the 43 reviews included in the overview, none explicitly theorised or defined acceptability. Measures used to assess acceptability focused on behaviour (e.g. dropout rates) (23 reviews), affect (i.e. feelings) (5 reviews), cognition (i.e. perceptions) (7 reviews) or a combination of these (8 reviews). From the methods described above we propose a definition: Acceptability is a multi-faceted construct that reflects the extent to which people delivering or receiving a healthcare intervention consider it to be appropriate, based on anticipated or experienced cognitive and emotional responses to the intervention. The theoretical framework of acceptability (TFA) consists of seven component constructs: affective attitude, burden, perceived effectiveness, ethicality, intervention coherence, opportunity costs, and self-efficacy.

CONCLUSION

Despite frequent claims that healthcare interventions have assessed acceptability, it is evident that acceptability research could be more robust. The proposed definition of acceptability and the TFA can inform assessment tools and evaluations of the acceptability of new or existing interventions.

Shedding the cobra effect: problematising thematic emergence, triangulation, saturation and member checking

CONTEXT

Qualitative research is widely accepted as a legitimate approach to inquiry in health professions education (HPE). To secure this status, qualitative researchers have developed a variety of strategies (e.g. reliance on post-positivist qualitative methodologies, use of different rhetorical techniques, etc.) to facilitate the acceptance of their research methodologies and methods by the HPE community. Although these strategies have supported the acceptance of qualitative research in HPE, they have also brought about some unintended consequences. One of these consequences is that some HPE scholars have begun to use terms in qualitative publications without critically reflecting on: (i) their ontological and epistemological roots; (ii) their definitions, or (iii) their implications.

OBJECTIVES

In this paper, we share our critical reflections on four qualitative terms popularly used in the HPE literature: thematic emergence; triangulation; saturation, and member checking.

METHODS

We discuss the methodological origins of these terms and the applications supported by these origins. We reflect critically on how these four terms became expected of qualitative research in HPE, and we reconsider their meanings and use by drawing on the broader qualitative methodology literature.

CONCLUSIONS

Through this examination, we hope to encourage qualitative scholars in HPE to avoid using qualitative terms uncritically and non-reflexively.

Realist theory construction for a mixed method multilevel study of neighbourhood context and postnatal depression

BACKGROUND

We have recently described a protocol for a study that aims to build a theory of neighbourhood context and postnatal depression. That protocol proposed a critical realist Explanatory Theory Building Method comprising of an: (1) emergent phase, (2) construction phase, and (3) confirmatory phase. A concurrent triangulated mixed method multilevel cross-sectional study design was described. The protocol also described in detail the Theory Construction Phase which will be presented here.

METHODS

The Theory Construction Phase will include: (1) defining stratified levels; (2) analytic resolution; (3) abductive reasoning; (4) comparative analysis (triangulation); (5) retroduction; (6) postulate and proposition development; (7) comparison and assessment of theories; and (8) conceptual frameworks and model development.

THEORY CONSTRUCTION

The stratified levels of analysis in this study were predominantly social and psychological. The abductive analysis used the theoretical frames of: Stress Process; Social Isolation; Social Exclusion; Social Services; Social Capital, Acculturation Theory and Global-economic level mechanisms. Realist propositions are presented for each analysis of triangulated data. Inference to best explanation is used to assess and compare theories. A conceptual framework of maternal depression, stress and context is presented that includes examples of mechanisms at psychological, social, cultural and global-economic levels. Stress was identified as a necessary mechanism that has the tendency to cause several outcomes including depression, anxiety, and health harming behaviours. The conceptual framework subsequently included conditional mechanisms identified through the retroduction including the stressors of isolation and expectations and buffers of social support and trust.

CONCLUSION

The meta-theory of critical realism is used here to generate and construct social epidemiological theory using stratified ontology and both abductive and retroductive analysis. The findings will be applied to the development of a middle range theory and subsequent programme theory for local perinatal child and family interventions.

Access to free or low-cost tuberculosis treatment for migrants and refugees along the Thailand-Myanmar border in Tak province, Thailand

Background

In Tak province, Thailand migrants and refugees from Myanmar navigate a pluralistic healthcare system to seek Tuberculosis (TB) care from a variety of government and non-governmental providers. This multi-methods qualitative study examined access to TB, TB/HIV and multidrug-resistant tuberculosis (MDR-TB) treatment with an emphasis on barriers to care and enabling factors.

Methods

In the summer and fall of 2014, we conducted 12 key informant interviews with public health officials and TB treatment providers. We also conducted 11 focus group discussions with migrants and refugees who were receiving TB, TB/HIV and MDR-TB treatment in Tak province as well as non-TB patients. We analyzed these data through thematic analysis using both predetermined and emergent codes. As a second step in the qualitative analysis, we explored the barriers and enabling factors separately for migrants and refugees.

Results

We found that refugees face fewer barriers to accessing TB treatment than migrants. For both migrants and refugees, legal status plays an important intermediary role in influencing the population’s ability to access care and eligibility for treatment. Our results suggest that there is a large geographical catchment area for migrants who seek TB treatment in Tak province that extends beyond provincial boundaries. Migrant participants described their ability to seek care as linked to the financial and non-financial resources required to travel and undergo treatment. Patients identified language of health services, availability of free or low cost services, and psychosocial support as important health system characteristics that affect accessibility.

Conclusion

Access to TB treatment for migrants and refugees occurs at the interface of health system accessibility, population ability and legal status. In Tak province, migrant patients draw upon their social networks and financial resources to navigate a pathway to treatment. We revised a conceptual framework for access to healthcare to incorporate legal status and the cyclical pathways through which migrants access TB treatment in this region. We recommend that organizations continue to collaborate to provide supportive services that help migrants to access and continue TB treatment.

Being alone and expectations lost: a critical realist study of maternal depression in South Western Sydney

The study reported here is part of a critical realist multilevel study. It seeks to identify and explain complex perinatal contextual social and psychosocial mechanisms that may influence the developmental origins of health and disease, with a focus on the role of postnatal depression. The aims of the greater study are to: (1) describe the phenomenon of postnatal depression in South Western Sydney; and (2) identify mechanisms that would add to our understanding of the psycho-social causes of maternal depression. This paper will move beyond our previous quantitative descriptions of individual-level predictors of depressive symptoms by seeking the views of local mothers and practitioners, to explain the mechanisms that might be involved. The study was set in South Western Sydney, New South Wales, Australia. An Explanatory Theory Building Method was used. The previously reported quantitative study was a non-linear principal component analysis and logistic regression study of 15,389 months delivering in 2002 and 2003. This intensive qualitative study used open coding of interviews, of seven practitioners and three naturally occurring mothers groups, to enable maximum emergence. The theoretical concepts identified were: attachment and nurturing, infant temperament, unplanned pregnancy and sole parenthood, support for mothers, access to services, stress, financial hardship, isolation and marginalisation, mothers' "loss of control" and "power", and expectations and dreams. Being alone and expectations lost emerged as possible triggers of stress and depression for mothers. These findings might also apply to others who have their dreams shattered during life's transitions. In these situations social and cultural context can either nurture and support or marginalise and isolate. The challenge for policy and practice is to support mothers and their partners during the transition to parenthood within a challenging social and material context.

Prevention through Design Adoption Readiness Model (PtD ARM): An integrated conceptual model

BACKGROUND

Prevention through Design (PtD), eliminating hazards at the design-stage of tools and systems, is the optimal method of mitigating occupational health and safety risks. A recent National Institute of Safety and Health initiative has established a goal to increase adoption of PtD innovation in industry. The construction industry has traditionally lagged behind other sectors in the adoption of innovation, in general; and of safety and health prevention innovation, in particular. Therefore, as a first step toward improving adoption trends in this sector, a conceptual model was developed to describe the parameters and causal relationships that influence and predict construction stakeholder "adoption readiness" for PtD technology innovation.

METHODS

This model was built upon three well-established theoretical frameworks: the Health Belief Model, the Diffusion of Innovation Model, and the Technology Acceptance Model. Earp and Ennett's model development methodology was employed to build a depiction of the key constructs and directionality and magnitude of relationships among them. Key constructs were identified from the literature associated with the three theoretical frameworks, with special emphasis given to studies related to construction or OHS technology adoption.

RESULTS

A conceptual model is presented. Recommendations for future research are described and include confirmatory structural equation modeling of model parameters and relationships, additional descriptive investigation of barriers to adoption in some trade sectors, and design and evaluation of an intervention strategy.

Social capital, socioeconomic status, and health-related quality of life among older adults in Bogotá (Colombia)

OBJECTIVE

The main goal of this study was to evaluate the relationship between levels of cognitive social capital and health-related quality of life (HRQOL).

METHODS

A multilevel, cross-sectional study was conducted in 2007 in Bogotá Colombia. A total of 1,907 older adults completed the Spanish version of the Short Form of Health Survey (SF-8) to assess HRQOL. Cognitive dimension of social capital was assessed. Hierarchical linear regressions were conducted to determine the associations between social capital variables and HRQOL.

RESULTS

Only 20% to 25% of the population reported trust in others and shared values. A total of 93% percent reported that people in their neighborhood would try to take advantage of them if given a chance. Higher social capital indicators were positively associated with the mental and physical dimensions of HRQOL.

DISCUSSION

Results from this study support evidence on the disintegration of the Colombian society, which may be influenced by high levels of social inequality.

Making sense of implementation theories, models and frameworks

BACKGROUND

Implementation science has progressed towards increased use of theoretical approaches to provide better understanding and explanation of how and why implementation succeeds or fails. The aim of this article is to propose a taxonomy that distinguishes between different categories of theories, models and frameworks in implementation science, to facilitate appropriate selection and application of relevant approaches in implementation research and practice and to foster cross-disciplinary dialogue among implementation researchers.

DISCUSSION

Theoretical approaches used in implementation science have three overarching aims: describing and/or guiding the process of translating research into practice (process models); understanding and/or explaining what influences implementation outcomes (determinant frameworks, classic theories, implementation theories); and evaluating implementation (evaluation frameworks). This article proposes five categories of theoretical approaches to achieve three overarching aims. These categories are not always recognized as separate types of approaches in the literature. While there is overlap between some of the theories, models and frameworks, awareness of the differences is important to facilitate the selection of relevant approaches. Most determinant frameworks provide limited "how-to" support for carrying out implementation endeavours since the determinants usually are too generic to provide sufficient detail for guiding an implementation process. And while the relevance of addressing barriers and enablers to translating research into practice is mentioned in many process models, these models do not identify or systematically structure specific determinants associated with implementation success. Furthermore, process models recognize a temporal sequence of implementation endeavours, whereas determinant frameworks do not explicitly take a process perspective of implementation.

Explaining ecological clusters of maternal depression in South Western Sydney

BACKGROUND

The aim of the qualitative study reported here was to: 1) explain the observed clustering of postnatal depressive symptoms in South Western Sydney; and 2) identify group-level mechanisms that would add to our understanding of the social determinants of maternal depression.

METHODS

Critical realism provided the methodological underpinning for the study. The setting was four local government areas in South Western Sydney, Australia. Child and Family practitioners and mothers in naturally occurring mothers groups were interviewed.

RESULTS

Using an open coding approach to maximise emergence of patterns and relationships we have identified seven theoretical concepts that might explain the observed spatial clustering of maternal depression. The theoretical concepts identified were: Community-level social networks; Social Capital and Social Cohesion; "Depressed community"; Access to services at the group level; Ethnic segregation and diversity; Supportive social policy; and Big business.

CONCLUSIONS

We postulate that these regional structural, economic, social and cultural mechanisms partially explain the pattern of maternal depression observed in families and communities within South Western Sydney. We further observe that powerful global economic and political forces are having an impact on the local situation. The challenge for policy and practice is to support mothers and their families within this adverse regional and global-economic context.

Realist explanatory theory building method for social epidemiology: a protocol for a mixed method multilevel study of neighbourhood context and postnatal depression

A recent criticism of social epidemiological studies, and multi-level studies in particular has been a paucity of theory. We will present here the protocol for a study that aims to build a theory of the social epidemiology of maternal depression. We use a critical realist approach which is trans-disciplinary, encompassing both quantitative and qualitative traditions, and that assumes both ontological and hierarchical stratification of reality. We describe a critical realist Explanatory Theory Building Method comprising of an: 1) emergent phase, 2) construction phase, and 3) confirmatory phase. A concurrent triangulated mixed method multilevel cross-sectional study design is described. The Emergent Phase uses: interviews, focus groups, exploratory data analysis, exploratory factor analysis, regression, and multilevel Bayesian spatial data analysis to detect and describe phenomena. Abductive and retroductive reasoning will be applied to: categorical principal component analysis, exploratory factor analysis, regression, coding of concepts and categories, constant comparative analysis, drawing of conceptual networks, and situational analysis to generate theoretical concepts. The Theory Construction Phase will include: 1) defining stratified levels; 2) analytic resolution; 3) abductive reasoning; 4) comparative analysis (triangulation); 5) retroduction; 6) postulate and proposition development; 7) comparison and assessment of theories; and 8) conceptual frameworks and model development. The strength of the critical realist methodology described is the extent to which this paradigm is able to support the epistemological, ontological, axiological, methodological and rhetorical positions of both quantitative and qualitative research in the field of social epidemiology. The extensive multilevel Bayesian studies, intensive qualitative studies, latent variable theory, abductive triangulation, and Inference to Best Explanation provide a strong foundation for Theory Construction. The study will contribute to defining the role that realism and mixed methods can play in explaining the social determinants and developmental origins of health and disease.

A closer look at the FTEM framework. Response to "More of the same? Comment on 'An integrated framework for the optimisation of sport and athlete development: a practitioner approach'"

The Foundations, Talent, Elite and Mastery (FTEM) framework was designed through the lens of a world leading high-performance sport agency to assist sporting stakeholders operationalise and research their whole of sport development pathways (Gulbin, J. P., Croser, M. J., Morley, E. J., & Weissensteiner, J. R. (2013). An integrated framework for the optimisation of sport and athlete development: A practitioner approach. Journal of Sport Sciences, 31, 1319-1331). In response to the commentary by MacNamara and Collins (2013) (Journal of Sports Sciences, doi:10.1080/02640414.2013. 855805), it was possible to document many inaccurate, false and misleading statements based on inattentive reading of the original article. We reinforce that: FTEM is a holistic framework of sport and athlete development and not a surrogate for a talent identification ( TID) model; bio-psycho-social components of development are liberally embedded throughout the FTEM framework; and the combined research and applied insights of development practitioners provide strong ecological validity for the consideration of stakeholders looking to explore applied approaches to athlete pathway management.

Neighborhood adversity, ethnic diversity, and weak social cohesion and social networks predict high rates of maternal depressive symptoms: a critical realist ecological study in South Western Sydney, Australia

The aim of the study reported here is to explore ecological covariate and latent variable associations with perinatal depressive symptoms in South Western Sydney for the purpose of informing subsequent theory generation of perinatal context, depression, and the developmental origins of health and disease. Mothers (n = 15,389) delivering in 2002 and 2003 were assessed at two to three weeks after delivery for risk factors for depressive symptoms. The binary outcome variables were Edinburgh Postnatal Depression Scale (EPDS)> 9 and > 12. Aggregated EPDS > 9 was analyzed for 101 suburbs. Suburb-level variables were drawn from the 2001 Australian Census, New South Wales Crime Statistics, and aggregated individual-level risk factors. Analysis included exploratory factor analysis, univariate and multivariate likelihood, and Bayesian linear regression with conditional autoregressive components. The exploratory factor analysis identified six factors: neighborhood adversity, social cohesion, health behaviors, housing quality, social services, and support networks. Variables associated with neighborhood adversity, social cohesion, social networks, and ethnic diversity were consistently associated with aggregated depressive symptoms. The findings support the theoretical proposition that neighborhood adversity causes maternal psychological distress and depression within the context of social buffers including social networks, social cohesion, and social services.

Methodological development of an exploratory randomised controlled trial of an early years' nutrition intervention: the CHERRY programme (Choosing Healthy Eating when Really Young)

Good nutrition in the early years of life is vitally important for a child's development, growth and health. Children's diets in the United Kingdom are known to be poor, particularly among socially disadvantaged groups, and there is a need for timely and appropriate interventions that support parents to improve the diets of young children. The Medical Research Council has highlighted the importance of conducting developmental and exploratory research prior to undertaking full-scale trials to evaluate complex interventions, but have provided very limited detailed guidance on the conduct of these initial phases of research. This paper describes the initial developmental stage and the conduct of an exploratory randomised controlled trial undertaken to determine the feasibility and acceptability of a family-centred early years' nutrition intervention. Choosing Healthy Eating when Really Young (CHERRY) is a programme for families with children aged 18 months to 5 years, delivered in children's centres in one urban (Islington) and one rural (Cornwall) location in the United Kingdom. In the development stage, a mixed-methods approach was used to investigate the nature of the problem and options for support. A detailed review of the evidence informed the theoretical basis of the study and the creation of a logic model. In the feasibility and pilot testing stage of the exploratory trial, 16 children's centres, with a sample of 394 families were recruited onto the study. We hope that the methodology, which we present in this paper, will inform and assist other researchers in conducting community-based, exploratory nutrition research in early years settings.

'The research compass': an introduction to research in medical education: AMEE Guide no. 56

This AMEE Guide offers an introduction to research in medical education. It is intended for those who are contemplating conducting research in medical education but are new to the field. The Guide is structured around the process of transforming ideas and problems into researchable questions, choosing a research approach that is appropriate to the purpose of the study and considering the individual researcher's preferences and the contextual possibilities and constraints. The first section of the Guide addresses the rationale for research in medical education and some of the challenges posed by the complexity of the field. Next is a section on how to move from an idea or problem to a research question by placing a concrete idea or problem within a conceptual, theoretical framework. The following sections are structured around an overview model of approaches to medical education research, 'The research compass'. Core to the model is the conceptual, theoretical framework that is the key to any direction. The compass depicts four main categories of research approaches that can be applied when studying medical education phenomena, 'Explorative studies'; 'Experimental studies'; 'Observational studies'; and 'Translational studies'. Future AMEE Guides in the research series will address these approaches in more detail.

Effectiveness of complex psycho-educational interventions for smoking relapse prevention: an exploratory meta-analysis

BACKGROUND

Existing systematic reviews have concluded that psycho-educational interventions for smoking relapse prevention were ineffective. Our objective was to conduct an exploratory meta-analysis, guided by mechanisms of these complex interventions for preventing smoking relapse.

METHODS

Relevant trials were identified from a Cochrane review and by an updated search of MEDLINE and PsycINFO (up to August 2009). We examined theories or mechanisms underlying relapse prevention interventions, and process variables reported in trials. Odds ratios (ORs) for the rate of smoking abstinence at the longest follow-up were pooled in meta-analysis.

RESULTS

Forty-nine trials were included, and interventions were at least partly based on the cognitive-behavioural approach to coping skills training in 41 trials. Only a few trials reported data on process variables. Coping skills training for smoking relapse prevention was effective for community quitters (OR 1.27, 95% CI: 1.08-1.49), and particularly for those who stopped smoking for at least 1 week at baseline (OR 1.52, 95% CI: 1.20-1.93). These findings were interpretable with mechanisms of coping skills training for relapse prevention.

CONCLUSIONS

On the basis of post hoc subgroup analyses, coping skills training for smoking relapse prevention is effective for motivated community quitters. This finding has important public health implications and needs to be confirmed by further trials.

Concentrated affluence, concentrated disadvantage, and children's readiness for school: a population-based, multi-level investigation

A number of studies demonstrates a relationship between neighbourhood concentration of affluence and disadvantage and the health and development of its residents. We contribute to this literature by testing hypotheses about the relationship between neighbourhood-level concentrated affluence/disadvantage and child-level developmental outcomes in a study population of 37,798 Kindergarten children residing in 433 neighbourhoods throughout the province of British Columbia, Canada. We utilise a previously-validated measure of neighbourhood socioeconomic composition--the Index of Concentration at the Extremes (ICE)--which not only allows for more precise estimation of the competing influences of concentrated affluence and disadvantage, but also facilitates examination of the potential impact of neighbourhood-level income inequality. Our findings show that increases in neighbourhood affluence are associated with increases in children's scores on the Early Development Instrument (EDI), a holistic measure of Kindergarteners' readiness for school. Particularly noteworthy is that, for four of the five EDI scales (physical, social, emotional, and communication) and the total score, results indicate a significant curvilinear relationship--whereby the highest average child-level outcomes are not found in locations with the highest concentrations of affluence, but rather in locations with relatively equal proportions of affluent and disadvantaged families. This finding suggests, first, that concentrated affluence may have diminishing rates of return on contributing to enhanced child development, and, second, that children residing in mixed-income neighbourhoods may benefit both from the presence of affluent residents and from the presence of services and institutions aimed at assisting lower-income residents. Implications and future directions are discussed.
