Methodological Considerations

AbstractNettle et al. evaluate evidence for the insurance hypothesis, which links obesity with the perception of food scarcity. Epidemiological findings in this area have generally been weak and inconsistent. The present commentary examines three key methodological issues arising from the literature on the association between obesity and the perception of food scarcity in humans, with suggestions for future epidemiological research.

AbstractBody image distortions are common in healthy individuals and a central aspect of serious clinical conditions, such as eating disorders. This commentary explores the potential implications of body image and its distortions for the insurance hypothesis. In particular, we speculate that body image may be an intervening variable mediating the relationship between perceived food scarcity and eating behavior.

And Control

Trust has been identified as a central characteristic of successful natural resource management (NRM), particularly in the context of implementing participatory approaches to stakeholder engagement. Trust is, however, a multi-dimensional and multi-level concept that is known to evolve recursively through time, challenging efforts to empirically measure its impact on collaboration in different NRM settings. In this communication we identify some of the challenges associated with conceptualizing and operationalizing trust in NRM field research, and pay particular attention to the inter-relationships between the concepts of trust, perceived risk and control due to their multi-dimensional and interacting roles in inter-organizational collaboration. The challenge of studying trust begins with its conceptualization, which impacts the terminology being used, thereby affecting the subsequent operationalization of trust in survey and interview measures, and the interpretation of these measures by engaged stakeholders. Building from this understanding, we highlight some of the key methodological considerations, including how trust is being conceptualized and how the associated measures are being developed, deployed, and validated in order to facilitate cross-context and cross-level comparisons. Until these key methodological issues are overcome, the nuanced roles of trust in NRM will remain unclear.

This paper presents a discussion of methodological issues that are relevant and idiosyncratic to cross-cultural research. One characteristic that typifies cross-cultural studies is their comparative nature, i.e., they involve a comparison across two separate cultures on a focal phenomenon. When differences across cultures are observed, the question arises as to whether the results are true cultural differences or merely measurement artifacts. Methodological considerations in cross-cultural research focus on ruling out alternative explanations for these differences and thus enhancing the interpretability of the results. The paper presents an overview of key methodological issues in cross-cultural research and reviews methods of preventing or detecting methodological problems.

Methodological Considerations

The literature on using serious games for learning has been growing exponentially during the last decade. It is time to examine some methodological issues associated with this line of research. There is evidence that research on serious games, if designed with methodological rigor and executed properly, such as the serial studies of prisoners’ dilemma, modality effect in individual interactive learning, and changes in attitude toward mathematics in a computer-based simulation game, can be fruitful and have a profound, positive impact on learning and training. Since adopting serious games as an educational technology tool is by no means cheap, we should ensure that methodological issues are carefully considered before conducting a study on educational games. Whereas there are excellent studies in the existing literature of simulations and games, it is not uncommon for some studies to adopt convenience samples or own-control designs. Studies on serious games tend to be conclusive if they have used true experimentation, well-controlled quasi-experimental design, surveys with representative samples and validated instruments, comprehensive design research, or training programs having a pretest–posttest design with group comparisons. The potential values and informative contributions of using different methodologies for serious game research should be recognized because of the ecological relevance. Future research should pay more attention to randomized sampling, controlled but feasible research design, validity of instruments, appropriate analytical methods, and interdisciplinary or cross-disciplinary research to enhance the internal/external validity of various approaches. In regard to analytical methods, both quantitative approaches and qualitative evaluations, if applied appropriately, are considered as valuable, indispensable, and complementary to each other. It is hoped that this chapter can be helpful not only for future researchers in this field to design and execute rigorous projects but also for wider readership to understand and evaluate research outcomes in the discipline of serious games.

Evaluation Of Care

Methodological considerations should be discussed within the context of emergency medical services (EMS) and disaster research. The fast pace and the information explosion of the society in which we live open new opportunities for epidemiological research and evaluation of care in disasters. The many methodological considerations necessary to generate useful and valid research is the topic of this article.I would like to discuss four major issues which raise a series of questions and suggest a variety of alternatives. The four major areas are: (l) the taxonomy required to do this type of research; (2) the elements of care; (3) comparative samples; and (4) planned as opposed to unplanned disasters.

Objective: To provide an updated review of condom migration as a means of highlighting methodological issues for future studies of this behavioural issue. Methods: Electronic searches of PubMed, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were carried out in October 2010 and updated in January 2011 for English-language articles published from 1994 onward. Results:Evidence addressing condom migration from microbicides and vaccines is vastly underdeveloped, simply because these products are still experimental. In contrast, the more advanced evidence regarding male circumcision is hopeful because it suggests that migration may not be an overwhelming issue. Nonetheless, the entire body of empirical evidence on this question could be substantially expanded and improved. Conclusion: Until stronger evidence suggests that condom migration is unlikely, it is important to be mindful of the potential for condom migration to occur in response to biomedical interventions (circumcision, microbicides and vaccines).

Neuropsychiatric Conditions

Epidemiology is the foundation of public health and rational planning of services. In the field of old age psychiatry, the information provided by epidemiological research has been highly influential. As the world older population is growing proportionally faster than the other age segments, there is a continuous need for further epidemiological research in old age psychiatry. Neuropsychiatric conditions, such as depression and dementia, cognitive impairment, behavioural and functional decline, place a considerable onus on the health, social and economic systems. This chapter presents some of the world demographic data and basic epidemiological concepts, discusses some methodological issues in the epidemiology of mental disorders in old age, and presents a summary of many of the most important studies in this field.

Key Questions

Delirium is a common and severe neuropsychiatric syndrome of brain dysfunction characterized by acute and fluctuating inattention and other cognitive and perceptual deficits precipitated by acute illness. Despite being first described by Hippocrates more than two thousand years ago, there exists considerable uncertainty regarding the diagnosis of delirium due to our limited understanding of fundamental concepts, including its definition and pathophysiology. The ensuing lack of standardization results in delirium being frequently undiagnosed and significant misclassification bias in existing research. This chapter discusses the descriptive epidemiology of delirium, including methodological issues around case ascertainment in different population and clinical settings. There remains a lack of epidemiological research in the field, but we indicate the potential for observational longitudinal studies to address key questions on the population impact of delirium alongside fundamental questions of major importance to patients and their families regarding outcomes after delirium.
