Epistemology • Epistemology is “the study of the nature of knowledge and justification” (Schwandt, 2001, p. 71*) • As shorthand, epistemology can be thought of as justification of knowledge. • For red refs, see hand-out.
methodology • “a theory and analysis of how research should proceed” (Harding, 1987, p. 2) • “analysis of the assumptions, principles, and procedures in a particular approach to inquiry” (Schwandt, 2001, p. 161) • methodology provides justification for the methods of a research project.
Methods • “techniques for gathering evidence” (Harding, 1987, p. 2) • “procedures, tools and techniques” of research (Schwandt, 2001, p. 158). • Methods can be thought of as research action.
In simple terms • Methodology justifies method, which produces data and analyses. Knowledge is created from data and analyses. Epistemology modifies methodology and justifies the knowledge produced
Qualitative research asks: • What is happening in the context – what do people do? • How do we know? Evidence of what is happening. Trustworthy – real to the social world of the participants • What else does it mean? Various levels of meaning: • To the participants • To the researcher • To the readership
Relationship between paradigms, methodology and data collection:
Phenomenology: The nature of the world cannot be fully known. All that can be known are people’s perceptions and interpretations of that world. In its strongest sense, phenomenology asserts that reality is only found in people’s minds, rather than external objects. One of the consequences of this is that reality is not a fixed entity, rather it changes and develops according to experiences and the social context within which they find themselves.
Social context is crucial: it is through our social interactions with others (e.g. health professionals, patients) that our understandings and preconceptions about the nature of reality are formed. This is not a one way process – it is through interaction with others that social realities are created.
Example of Implications:: Benner & Wrubel (1989) - ‘illness as a human experience of loss or dysfunction has a reality all of its own’. Rejects the (then) medical model of how we can view illness. What have been the implications of this type of finding to understanding health practice?
Phenomenology ‘Descriptive phenomenology’ Husserl (1859 – 1938) ‘What do we know as persons?’ Bracketing, Intuiting, Analyzing, Describing ‘Interpretive phenomenology’ Martin Heidegger (1889 – 1976) ‘What is being?’ No bracketing Hermeneutics
Interviews • Highly Structured – structured questions, fixed wording, fixed sequence. • Semi-structured – focussed questions, outline sequence but may vary • Unstructured – open questions, conversational approach
Interview data in Qualitative designs • Semi-structured or unstructured interviews are most common in qualitative research • Provide large amounts of relatively unconstrained data • Structure varies according to research methodology and amount of focus required to address research questions
ETHNOGRAPHY To learn from a cultural group The process of describing a culture/way of life from peoples' point of view. Another name for it is field research. Each person is a reflection of their culture: gestures, symbols, sayings has implicit, tacit meaning for others in that culture.
Uses PARTICIPANT-OBSERVATION The process of immersing yourself in the study of people you're not too different from: Aim – to attain ‘insiders’ view of the group under study It is almost always done covertly,
Lots of note taking: Involves observation and note taking. Anthropologist Clifford Geertz ‘thick description’. For about every half hour of observation, an ethnographic researcher would write notes for about two hours. These notes would contain rich, detailed descriptions of everything that went on. The notes would capture as factual a description of the drama as possible to permit multiple interpretations, and most of all, to later infer cultural meaning. A coding procedure (much like content analysis) would be used later for this.
Despite being well established, it is not popular in nursing – it is difficult for health professionals to participate in the social world of patients. However health professionals can participate in the world of other health professionals: Porter (1992) looked at the influence of gender on nurses professional relationships with medics by gathering data whilst working as a staff nurse on an intensive care ward, and so able to immerse into the occupational social world of the ICU nurse.
Observation • This method is used where there is a need to go ‘beyond what people say’. • Researcher may observe as • An outsider – unacknowledged by observees • An outsider – acknowledged by observees • A participant (participant observation) • This affects the nature of the observation • This also raised ethical considerations
Observations • Observations may be: • Highly Structured • fixed categories, often ‘tick-box’, produces numerical counts • Semi-structured • focussed observations, broad categories, data recorded in field notes • Unstructured • general observations, many aspects recorded, data recorded in field notes
Observational data May be collected by; • Detailed written notes- during and after event • Audio recording (of thoughts, description, of setting) • Video recording (of setting, of behaviour)
‘Hawthorne effect’ • Although there is less chance in observed data that people will ‘tell you what you want to hear’ • There is some evidence that observation alone may change how people behave • Hawthorne effect
CASE STUDY One person you want to generalise to others of that type. Social Work and Clinical Psychology have embraced the value of a single-subject (sample size N=1) or case study approach. Almost all case studies involve unstructured interview The idea is to find a subject so typical that he/she seems to reflect others.
Descriptive qualitative research Advantages: Avoids ‘methodology’ Researcher has freedom to construct research process Focus on results Disadvantages: No guidelines Can lack internal coherence Lack of information on process
Qualitative content analysis • The goal of content analysis is “to provide knowledge and understanding of the phenomenon under study” (Downe-Wamboldt, 1992, p. 314). • to examine data for the purpose of classifying large amounts of text into categories • (Weber, 1990). • For refs, refer to green reference
the systematic classification process of coding and identifying themes or patterns. • focuses on the characteristics of language as communication with attention to the content or contextual meaning of the text (Budd, Thorp, & Donohew, 1967; Lindkvist, 1981; • McTavish & Pirro, 1990; Tesch, 1990).
Text data might be in verbal, print, or electronic form and might have been obtained from narrative responses, open-ended survey questions, interviews, focus groups, observations, or print media such as • articles, books, or manuals (Kondracki &Wellman, 2002).
Grounded Theory (Glaser & Strauss (1967): The development of theory from data which has been methodically collected from real life setting Ideally suited to investigation of topics of which little is known about. Concurrent collection of data, organisation and analysis.
4. Action research Kurt Lewin – 1940s Participatory Non-participatory
Focus groups • Data from small numbers of people is collected simultaneously • Large amounts of data quickly • Interaction generates lively debate • Group management and recording data accurately can be a problem.
QualitativeTerms Question formation: Explore Perceptions Credibility of findings: Trustworthiness Applicability
Terms to avoid Inappropriate/debateable terms Prove Hypothesis Bias Validity Reliability Generalizability
Data: Let’s Play 30 mins. Half group will be ethnographers, and half phenomenologists. Ethnogrophers – pen and paper, go an be a participant observer in the canteen. Make lots of notes about what you observe. Be patient and concise. Phenomenologists: Construct an interview schedule about being a student and working (unstructured or semi). Interview a colleague. Make notes about the interview.
Be clear, qualitative research • is not an exact process • But it does illuminate/provide a picture of a social reality at a time for a sample (don’t underestimate the power of sample) • All you can do is present a snapshot • You aim to make this as credible/intelligible as possible to yourself, to other researchers and to the participants (tell the story) • There will always be limitations, irrespective of paradigm/methodology/method of data collection…………

QUALITATIVE RESEARCH METHODOLOGY Methodology concerns questions about the manner in which knowledge about what exists can be gained. Frames of the Qualitative Research
Recording data from interactive accounts • Interviews and focus group data is usually recorded • Audio • Video • Written • And then transcribed – i.e. converted to type- before analysis
Setting- where you get your data from • Do you have access to the setting? • Will you need to find a ‘gatekeeper’? • Will you need special permission to access the setting? • Security clearance for prisons, government departments etc • R&D permission for NHS sites • Letters of introduction to view certain archives
Collecting data regarding the setting • The setting may or may not be relevant to the data you intend to collect. • If it is relevant then data regarding the setting may be collected in a number of ways. [Consider when setting may be relevant]
Things to consider • Ethics • Analysis • Access • Expense • Time • More on thisw later.
Analysis • How do I hope to analyse the data? • What implications does this have for how I collect and store it?
Data analysis Common terms – domains, taxonomic, units, themes, codes, theories Descriptive - Burnard Ethnography - Spradley Phenomenology – Colaizzi, Giorgi, Van Manen Grounded theory – Glaser and Strauss or Strauss and Corbin
Coding • http://onlineqda.hud.ac.uk/Intro_QDA/how_what_to_code.php • The process of combing the data for themes, ideas and categories
Data Analysis. • Lets start coding! • What have we found? • What are our preliminary concussions? • How reliable, trustworthy are they?
