This chapter outlines the methodology and methods applied to answer the research question. In line with the objectives and the Medical Research Council’s (MRC) framework for the development and evaluation of complex interventions, there are two phases of this study: the design and development of the intervention and the feasibility testing of the intervention. These two phases will be described after a brief description of the philosophical approach taken, shaping the overall epistemology. 4.1.1. Critical Realism Following a review of various philosophical stances, I chose critical realism as the philosophical foundation for this study as it aligns with my view about the nature of the world. Critical realism is a post positivist theory …show more content…

The first phase, the development phase, is of great importance, as it can determine the success of the overall evaluation and implementation process. The second phase of the framework is concerned with the feasibility and pilot testing of the intervention. In order to address the feasibility, acceptability and practicality of a stigma protection intervention the designed intervention will be subjected to feasibility randomised controlled trial, which is believed to be the most suitable method to evaluate the preliminary evidence of effectiveness of an intervention (Lancaster et al., 2004). A feasibility study is a study designed to build the foundations for a planned intervention study (Tickle-Degnen, 2013). The purpose of most feasibility studies is to describe information and evidence related to the successful implementations and validity of a planned full trial and to reduce threats to the validity of these studies (Tickle-Degnen, 2013). The primary tests of the intervention effectiveness should occur in the main study, not in the studies that test feasibility (Teare et al. 2014). The analyses are therefore mainly descriptive and focus on confidence interval estimations and not on inferential testing (Lancaster et al., 2004; Lancaster, 2015, Leon, Davis and Kraemer, 2011). As the RCT is exploratory and aiming to inform the design of a future larger trial, the trial also includes a process evaluation. This involves a qualitative focus group with a sample of participants to explore their experiences of the intervention, and the acceptability of the outcomes

  • Neorealism Essay

    1006 Words  | 3 Pages

    Italian Neorealism, a movement that focused on the arts began in 19th century post war Italy and “became the repository of partisan hopes for social justice in the post war italian state.” (Marcus, xiv) Even before the war, Italy had been under the dictatorship of Benito Mussolini and his corrupt form of government, Fascism, which caused oppression throughout the country. Neorealistic films allowed filmmakers to use common styles and techniques to finally reveal the world filled with anguish and misery that Mussolini had created. These films allowed the rebirth of Italy with the new ideals of freedom and social order. Some directors choose to add melodramatic elements to their neorealistic film which goes against Neorealism’s goal to project the Italy in its real form. However, although Rome Open City by Roberto Rossellini and Bitter Rice by DeSantis have classic hollywood narrative characteristics, the portrayal of women and children represent neorealist principles that help us further understand the struggles and conflicts of women and children during post-war Italy.

  • Essay On Postmodernism

    1960 Words  | 4 Pages

    Postmodernism has always been somewhat present during every generation of people in America. In fact, it alludes to future ideas that are cutting edge when compared to the theologies of the modern times. The Emergent church can be classified as postmodern, because it is in fact an “emerging” movement. Perhaps the question we should ask is if it’s just a phase in America, or is it here to stay? We should first answer the questions that it brings up, before we can answer what it actually represents. However, there is one thing we do know, which is that the name comes from the fact that this “movement” is gradually changing the philosophy of Christianity.

  • Epistemology Essay

    The ontology and epistemology of the researcher influences the design of tools for health education. However, it is imperative that the researcher is aware of, one’s own culture, values, assumptions and beliefs (7), and recognizes how these inherent biases/prejudices may influence the design of health education tools. The researcher must be mindful of the target population’s ontology and way of learning so as to ensure that the tool provides learning and information in the manner familiar and comfortable to the recipients as this will increase learning and produce sustainable change. Most importantly, the underlining theory that guides the design of the tool must be commensurate with Indigenous epistemology.

  • Epistemology Essay

    605 Words  | 2 Pages

    Epistemology is the branch of philosophy that studies knowledge. It is mainly concerned with the nature and scope of knowledge. It attempts to answer the basic question of what distinguishes true or adequate knowledge from otherwise false or inadequate knowledge (Heylighen). The major branches of epistemological theory are rationalism, empiricism and mysticism. Rationalism implies that knowledge is obtained through reason and introspection. Ones ideas are justified by sense experience, but if the senses and intuition are in conflict, the sensory evidence must be discarded. In empiricism, knowledge is obtained through observation and experiment. Models and theories may be used to organize this sensory experience, but if theories contradict experience they are wrong. In mysticism, knowledge is obtained through faith, emotions or revelation but if observation or intuition contradict, the knowledge is thus deemed wrong (“Rationalism”). Doubt, as a Persian Proverb once said, is the key to knowledge. It is one of the influencing factors in the expansion of knowledge. A fact that is conside...

    Evidence-based practice is important to consider when researching for interventions, further knowledge, or help to guide a new idea in the health professions. Evidence-based practice is comprised of three significant concepts: respect and awareness for the targeted population’s values, previous clinical practice or experience with that population, and systematic research to establish a better understanding of what is already known about the study’s focus. These concepts are all taken into consideration when designing and conducting a study because it provides a more valid and credible source for others.

    Christine Reigner Amy Dean English 242 24 March 2014 Realism versus Romanticism in the Victorian Age The Victorian Age demonstrates the changes that were going on in the seventeenth and early eighteenth centuries in England. England was the first to experience change in industry and become the first industrial nation, “Because England was the first country to become industrialized, its transformation was an especially painful one” (NAEL 1018). This is the time where realism overcame romanticism in literature. Realism was displayed in many different works and differed greatly from romanticism in several ways.

  • Scientific Realism Essay

    787 Words  | 2 Pages

    Scientific realism states that our knowledge of an object is acquired by the ideas created from our experience of it, not from direct perceptions. Our ideas are not the object itself but a representation of it. The theory states that the world is of mind-independent objects (people, animals, trees, and etc.). It also states that we cannot directly perceive external objects. What we perceive are the copies of the representations of the external objects. Such as what we view on the television are copies of their remote causes (such as a concert or people on a playing field), so the images (who are visual, auditory, and etc.) that are occurring in the mind represent (or when things are not working, misrepresent) the external physical objects.

  • Reality Essay: Real, Reality, And Reality

    Each day, people wake up in their beds to find things exactly as they left it. The sky's still blue, the leaves are still green, and the pile of dirty laundry still sits at the bottom of their bed. This world of known qualities, filled with objects we consider to be real, is often referred to as reality. A simplistic definition of the word reality would be “the state or quality of having existence or substance” (Definition). But what exactly does this mean? For example, a world where everything that must be felt, seen, tasted, or heard in order to be considered “real”, does not account for the molecules that dance under our nose or the germs on our fingers. Therefore, when one takes a closer examination of the meanings of the words real, reality,

  • Modernism Essay

    2176 Words  | 5 Pages

    The advancement of sociological theory and philosophy into modernism and postmodernism has been a truly self-reflexive era of inspection of practices. A key intellectual here is Michel Foucault with his archeological analysis of punitive practices. More contemporary and darker sides of modernity have a similar methodological strife with positivist thought. A major question that modernists and postmodernists face is about legitimacy of discourse and practice. Specifically in academia as Foucault makes clear academia is intertwined with power. To understand legitimate power, we must view it through the lens of its practice. Postmodernists and some modernists moved away from a mystified critique of structures and actors and instead focused its discourses on practices, ideas, and conceptualizations.
