QUALITATIVE RESEARCH DESIGNS

By:- Firoz QureshiDept. Psychiatric Nursing

QUALITATIVE PARADIGM

Naturalistic paradigm Soft science Focus: usually broad Holistic Subjective Reasoning: dialectic, inductive Basis of knowing: meaning, discovery Shared interpretation Communication and observation Basic element of analysis: words Individual interpretations Uniqueness

The “Logic” of Qualitative Research

Based on holistic view & following beliefs:(1) There is no single reality – reality is based on

perceptions – it is different for each person – changes over time

(2) What we know has meaning only within a given situation or context

The reasoning process in qualitative research involves:

- perceptually putting pieces together to make wholes

What is the concept of “Gestalt”?

This concept is closely related to “wholism” and proposes that a particular phenomenon is organized into a cluster of linked ideas, “a gestalt”.

Disadvantage:- understand a phenomenon through the

interpretation of a particular theory

Experiencing “Gestalt Change”

First to deconstruct your original sedimented views

Reconstruct another view

Focus on a different view point or looking at something differently (a different lens)

To increase openness

Philosophy and Qualitative Research

Frameworks are not used the same as in quantitative

The goal is not theory testing Each study should be guided by a particular

philosophical stance

Philosophical Stance assists to: (a) directs the question(s) that are asked(b) the observations which are made (c) the interpretation of data

DESIGN OF QUALITATIVE STUDIES

Specify design before data collection Adhere to the design after study started Study design evolves over time Researcher Decisions include:(a) How to obtain(b) From whom to collect(c) How to schedule(d) How long

Design of Qualitative Research

EMERGENT DESIGN A design that emerges as the researcher makes

ongoing decisions reflecting what has already been learned

Lincoln & Cuba (1985) – not researcher laziness or sloppiness – but rather desire to base inquiry on realities and viewpoints of those under study

Key: realities and viewpoints that are NOT KNOWN or UNDERSTOOD AT THE OUTSET

Characteristics of Qualitative Research Design

Flexible, elastic, capable of adjusting Merging together of various data collection strategies Holistic, understand the whole Research intensely involved Research to become the research instrument Requires ongoing analysis of data to formulate

subsequent strategies and to determine when field work is done

What is “Bricolage?”

Qualitative Designs

PHASES of a Qualitative Study:

(1) Orientation an overview(2) Focused exploration(3) Confirmation and closure

(Lincoln & Cuba, 1985)

Qualitative Design Features

Control over the independent variable

Type of group comparisons

Number of data collection points

Occurrence of the independent & dependent variables

Qualitative Research Traditions

Four traditions described by nurse researcher:

(1) Ethnography(2) Phenomenology(3) Grounded Theory(4) Historical Research

ETHNOGRAPHY

Research tradition in anthropology Provides a framework for studying meanings,

patterns, and experiences defined by a cultural group in a holistic fashion

Ethnoscience (Cognitive Anthropology): focuses on the cognitive world of a culture – semantic rules and shared meanings that shape behavoir

ETHNOGRAPHY

Focus: the culture of a group of people Assumption: every human group evolves a

culture that guides members view of the world and the way they structure their experiences

At times referred to as “macroethnography: - able to study broadly defined cultures

At times referred to as “microethnography” – able to study cultures using a very narrow focus

Ethnography Cont’d

Aim: to learn from rather than study members of a cultural group

Two perspectives:(1) Emic – insider’s view, the way the members of a

culture envision their world(2) Etic - outsiders’ interpretation of the

experiences of that culture – strive to get at cultural experiences that members do not talk about or may not even be consciously aware


Extensive field work Typically labor intensive Time consuming

Researcher as instrument - to study a culture it requires a certain level of intimacy – needs to be developed – become one within the culture


Three types of information:(1) Cultural behavoir(2) Cultural artifacts(3) Cultural speech

Sources of information – in-depth interviews, records, charts, observations and other types of physical evidence are used


Products of this research includes:- rich and holistic descriptions- describe normative behavoir and social patterns- Information about health beliefs and health practices- Facilitates an understanding of behavoirs affecting health

and illness- Leininger coined the phrase:

“ethnonursing research” –the study and analysis of local or indigneous people’s viewpoints, beliefs and practices

about nursing care behavoir and processes of designated cultures

Phenomenology

Phenomenology is both philosophy and a research method

Purpose of this research method is to describe experiences as they are lived – to capture the

“lived experience”

Developed by Husserl & Heidegger – an approach to thinking about people’s life experiences.

Phenomenology Cont’d

Philosophical Orientation- view the person as integral with the

environment- World is shaped by the self and also shapes

the self- The person is a self within a body- Person is referred to as “embodied” – our

bodies provide the possibility for the concrete actions of self in the world


A phenomenological researcher asks the question:“What is the essence of this phenomena as experienced by these people and what does it

mean?”

Assumption: there is an “essence” an essential variant structure Investigates subjective phenomena Belief that truths about reality are grounded in

peoples’ lived experiences


Four aspects of the lived experience:

(1) SPATIALITY

(2) CORPOREALITY

(3) TEMPORALITY

(4) RELATIONALITY


Data sources: In-depth conversations Researcher helps the participant to describe lived

experiences without leading the discussion Two or more interviews/conversations are needed Usually small number of participants (ie. 10 or

less) May use participation, observation and

introspective reflection

Grounded Theory

Is an inductive research technique developed for health-related topics by Glaser & Strauss (1967)

Emerged from the discipline of sociology

“Grounded” – means the theory developed from the research is grounded or has it roots in the data from which is was derived

Grounded Theory Cont’d

Philosophical Orientation: Based on symbolic interaction theory Explores how people define reality and how their

beliefs are related to their actions Meaning is expressed through – symbols – such as

words, religious objects, and clothing Symbolic meanings are different for each of us In social life - meanings are shared by groups –

socialization process Group life is based on consensus and shared

meanings


Is an approach to study the social processes and social structures

Focus: is the evolution of a social experience – the social and psychological stages that characterize a particular event of process


Methodology:- does not begin with a focused research question- the question emerges from the data

- fundamental structure feature – is the “data collection” is the “data analysis” Is the sampling of participants occurs

simultaneously This procedure is referred to as “constant

comparison”


Constant Comparison: is used to develop and refine theoretically relevant categories and to identify the basic problem

Categories that are elicited from the data are constantly compared with data obtained earlier so that “commonalities” and “variations” can be determined

Categories can be “condensed” and “collapsed”


Data Sources:

- in-depth interviews are most common- Observational methods- Existing documents

- Usually a sample of 25 to 50 informants

- Has contributed to the development of middle range nursing theories

Historical Research

Historiography examines events of the past Historians believe the greatest value of historical

knowledge is an increased self-understanding

Philosophical Orientation: A very old science Primary question “Where have we come from, who

are we, and where are we going?” Myths, past, present and future are not

distinguishable Myths are a form of story telling

Historical Research Cont’d

History moves beyond the myth Chronicling events, deeds, victories and stories

about people and civilizations Comparing histories, identifying patterns

Aim: to discovery new knowledge Seeking to answer questions concerning causes,

effects and trends relating to past events To shed light on present behaviors and practices

Historical Research Cont’d

Assumptions:

(a) There is nothing new under the sun

(b) One can learn from the past

Sampling in Qualitative Research

Usually small, non-random samples Concern: measure attributes and relationships in

a pop’n Need a representative sample

Aim: to discover meaning, uncover multiple realities, therefore generalization is not a guiding criteria

Sampling in Qualitative Research

Types of sampling:

(1) Convenience sampling(2) Snowball sampling(3) Theoretical sampling(4) Purposeful sampling – several strategies –

maximum variation sampling, extreme/deviant case sampling, and typical case sampling

(5) Simple random

Sample Size

No firm establishment of criteria or rules Should be determined on the basis of

informational needs

Is largely a function of:(a) the purpose of the inquiry(b) the quality of the informants(c) The type of sampling strategy used

Sample Size

Guiding Principle is that of,

DATA SATURATION: sampling to the point at which no new information is obtained and redundancy is achieved

Critiquing the Sampling Plan

Evaluate the sample plan based on the following:

(a) Terms of its adequacy(b) Terms of its appropriateness

Adequacy means –

Appropriateness means -

Assessment of Qualitative Data

Need to address validity and reliability Do the measures used by the researcher yield data

reflecting the truth?

Lincolon & Cuba (1985) – four criteria:(1) Credibility(2) Dependability(3) Confirmability(4) Transferability(criteria for establishing “trustworthiness”)


Credibility – refers to confidence in the truth of the data

Prolonged engagement Persistent observation Triangulation External checks – peer debriefing & member

checks Researcher credibility


Dependability – refers to data stability over time and over conditions

Steps to approach:

(a) Stepwise replication(b) Inquiry audit


Confirmability –refers to the objectivity or neutrality of the data – what does that mean?

AUDIT TRAIL:

Transferability – refers to the extent to which the findings from the data can be transferred to other settings or groups = similar to the concept of generalizability
