WHAT IS QUALITATIVE RESEARCH?

Qualitative research is a type of scientific research that:

• seeks answers to a question• systematically uses a set of procedures to

answer the question• collects evidence• produces findings that were not determined in

advance• produces findings that are applicable beyond

the immediate boundaries of the study

5

Page 6: Qualitative Research-  What it is and when to use it

CHARACTERISTICS OF QUALITATIVE RESEARCH Starts with general

question or problem No pre-defined

hypothesis Uses a purposeful

sample, not a random one

Uses a relatively small sample

Data collected with semi-structured and unstructured instruments

Presents results descriptively

Utilizes researcher’s awareness of own orientations, biases, experiences that might affect data collection and interpretation

QUALITATIVE RESEARCH

‘Qualitative Research…involves finding out what people think, and how they

feel - or at any rate, what they say they think and how they say they feel. This

kind of information is subjective. It involves feelings and impressions,

rather than numbers’

Bellenger, Bernhardt and Goldstucker, Qualitative Research in Marketing, American Marketing Association (1976) 7

Page 8: Qualitative Research-  What it is and when to use it

QUALITATIVE METHODS ARE USED To gain more in-depth information that may bedifficult to convey quantitatively To better understand any phenomenon aboutwhich little is yet known or knowledge isincomplete To gain new perspectives on things about whichmuch is already known

QUALITATIVE VS. QUANTITATIVE Typically qualitative research will provide in-depth

information into fewer cases whereas quantitative procedures will allow for more breadth of information across a larger number of cases.

Benefits of combining qualitative and quantitative procedures, resulting in greater methodological mixes that strengthen the research design

COMBINING QUALITATIVE AND QUANTITATIVEQualitative data collection can be used in four different ways in relation to quantitative methods:1. Precede quantitative procedures2. Used at the same time as quantitative

procedures3. Follow quantitative procedures4. Used alone

OPEN AND CLOSED QUESTIONS (FROM OPPENHEIM, 1992)

Strength LimitationOPEN Freedom & spontaneity of

answerTime-consuming

Opportunity to probe Coding more problematicUseful for testing hypothesis about ideas or awareness

More effort from respondents

CLOSED Requires little time Loss of spontaneous responses

No extended writing Bias in answer categoriesLow costs Sometimes too crudeEasy to process May irritate respondentsMake group comparisons easyUseful for testing specific hypothesis

Page 17: Qualitative Research-  What it is and when to use it

OPEN-ENDED QUESTIONS Typically used in exploratory/qualitative

studies. Typically used in personal interview surveys

involving small samples. Allows respondent freedom of response. Respondent must be articulate and willing to

spend time giving a full answer. Data is in narrative form which can be time

consuming and difficult to code and analyze. Possible researcher bias in interpretation. Narrative can be analyzed using content

analysis. Software is available.17

IN-DEPTH INTERVIEWS21

Page 22: Qualitative Research-  What it is and when to use it

IN-DEPTH INTERVIEWAn in-depth interview is a formal interview process in which a well-trained interviewer asks a subject a set of semi-structured questions in a face-to-face setting.

Along with questionnaires, interviews are the most common form of data collection.

22

Page 23: Qualitative Research-  What it is and when to use it

Interviews are usually grouped on a continuum as follows:Structured Semi–structuredUnstructured

Interviews

23

Page 24: Qualitative Research-  What it is and when to use it

STRUCTURED Closed fixed-response interview- quantitative

interviewing Predetermined set of response categories

Standardized open-ended interview- qualitative interviewing Interviewers closely follow the ‘script’ of

the interview questionsResponses are open-ended

24

Page 25: Qualitative Research-  What it is and when to use it

STANDARDIZED OPEN ENDED INTERVIEW Useful for reducing bias

When several interviewers are involved When interviewers are less experienced or

knowledgeable When it is important to compare the responses of

different respondents Most efficient qualitative interviewing technique

Reduces amount of time and money needed for analysis

Drawback Interviewer has little flexibility to respond to the

particular concerns of the individual No guarantee that the questions asked tap into the

issues that are most relevant to this particular respondent. 25

Page 26: Qualitative Research-  What it is and when to use it

SEMI-STRUCTURED Semi – structured interviews are those that

incorporate both closed and open questions, and are more concerned with explanation of motives, actions and thoughts.

The interviewer may also look for further information, for example asking

“Why do you think that?” “What happened next” “What exactly do you mean?”

If something unanticipated comes up the interviewer can follow-up.

26

Page 27: Qualitative Research-  What it is and when to use it

UNSTRUCTURED An unstructured interview

is one where the interviewer has a theme they wish to talk about, or a topic guide that lists a number of themes.

In both semi – structured and unstructured interviews the order in which you ask the questions is not so important.

Sometimes the interviewee may answer a question before it is asked.

27

Page 28: Qualitative Research-  What it is and when to use it

INTERVIEWING Sometimes the interviewee may go off on a

tangent, and reveal something new, but sometimes they may go off on a tangent and not reveal anything worth having.

The less structured an interview is, the more like a conversation it becomes.

However, it is not the same as a conversation as the interviewer needs to keep it focused on the research questions.

28

Page 29: Qualitative Research-  What it is and when to use it

INTERVIEWING The interviewer also has to play the role of being

a good listener. How the question is formulated and asked is very

important. Leading, loaded, or ‘trick’ questions should be

avoided, for example“I don’t like the current policy on child care

provision, what do you think?” “When did you stop taking drugs?”"Given that at the age of 18 people are old

enough to fight and die for your country, don't you think they should be able to drink alcohol as well?"

29

Page 30: Qualitative Research-  What it is and when to use it

INTERVIEWING

Avoid normative questions which require the interviewee to give a socially acceptable answer.

Avoid over long or complicated questions, specialist language and jargon that the interviewee will not understand but bear in mind that in some instances interviewees will use specialist words and jargon.

Pre-test questions. Establish and maintain rapport during the

interview.30

Page 31: Qualitative Research-  What it is and when to use it

INTERVIEWER RESPONSESWhyte’s hierarchy of interviewer responses:

'Uh-huh‘ 'That's interesting‘Reflection - Repeating the last statement as a

questionProbe - Inviting explanations of statements Back trackingNew topic

31

Page 32: Qualitative Research-  What it is and when to use it

PROBINGProbing distinguishes the trained interviewer from untrained. The untrained interviewer has the tendency

to think ahead, to think of the next question in the guide, hurrying to move on.

The trained interviewer listens attentively to each answer to evaluate if the answer is adequate. If the answer is not adequate, the interviewer thinks, in a few seconds, about the possible cause and asks a good question to get more precise and complete information.

32

Page 33: Qualitative Research-  What it is and when to use it

INTERVIEWING

It is best to record the interview with a digital voice recorder.

Taking verbatim notes is very difficult unless the interviewer can write in shorthand.

It takes a long time to transcribe interviews. The usual estimate is that it takes 3 hours to transcribe 1 hour of recording.

It can be a tiring process for both parties so don’t schedule more than a few a day.

33

Page 34: Qualitative Research-  What it is and when to use it

QUALITATIVE INTERVIEWING IS MOST USEFUL FOR: Evaluating programs that are aimed at

individualized outcomes Capturing and describing program processes Exploring individual differences between

participants' experiences and outcomes Evaluating programs that are seen as

dynamic or evolving Understanding the meaning of a program to

its participants Documenting variations in program

implementation at different sites

34

Page 35: Qualitative Research-  What it is and when to use it

QUALITATIVE INTERVIEWING IS NOT AS USEFUL FOR: Evaluating programs that emphasize

common outcomes for all participants Measuring specific, predetermined effects of

a program on participants In impact evaluations, deciding whether the

intervention caused changes or effects in participants (since determining causality requires more controlled conditions)

35

Page 36: Qualitative Research-  What it is and when to use it

SUMMARY Interviewing is a good way to explore

people’s attitudes and values towards certain topics and situations and gain a fuller understanding of their motivations and actions.

However, they are time consuming and labor intensive and for those reasons are only done with small samples.

What you lose in breadth you make up for in depth.

FOCUS GROUPS38

Page 39: Qualitative Research-  What it is and when to use it

DEFINITION OF A FOCUS GROUP A carefully planned discussion

designed to obtain perceptions on a defined area of interest in a permissive, nonthreatening environment.

Discussion is relaxed, comfortable, and often enjoyable for participants as they share their ideas and perceptions.

Group members influence each other by responding to ideas and comments in the discussion. 39

Page 40: Qualitative Research-  What it is and when to use it

MAIN PURPOSE OF A FOCUS GROUP In a one to one interview, the interviewer will

ask the interviewee to explain certain thoughts and actions.

In focus groups it is often the participants themselves who will ask each other to explain certain actions/thoughts.

Focus groups allow us to study the ways in which individuals make sense of particular topics and construct social meanings around it.

40

Page 41: Qualitative Research-  What it is and when to use it

FOCUS GROUPS Focus groups produce qualitative data

through the use of open-ended questions that provide insights into the attitudes, perceptions, and opinions of participants.

Particularly appropriate procedure to use when the goal is to explain how people regard an experience, idea, or event.

Group discussion is conducted several times (about four) with similar types of participants to identify trends and patterns in perceptions.

Researcher conducts a careful and systematic analysis of the discussions. 41

Page 42: Qualitative Research-  What it is and when to use it

GROUP MAKEUP Conducted with approximately seven to ten

people by a skilled interviewer. Researcher serves several functions:

moderating, listening, observing, and analyzing using an inductive process.

Neutral moderator similar to participants (age, gender, race, etc.)

42

Page 43: Qualitative Research-  What it is and when to use it

PARTICIPANTS Unfamiliar with each other

(preferably strangers) Selected because they have

certain characteristics in common that relate to the topic of the focus groupAgeGenderOccupationMarital statusSimilar attitudes

43

Page 44: Qualitative Research-  What it is and when to use it

TOPICS OF DISCUSSION Carefully predetermined and sequenced open

ended questions (about 5 – 6 questions) Understandable and logical to the participant Avoid dichotomous questions (yes/no)

44

Page 45: Qualitative Research-  What it is and when to use it

PLANNING Inviting people may require a lot of phone

calls and planning. Need some incentive for people to attend

such as food and drink, travel expenses or a gift voucher as a form of payment.

Two facilitators/moderators, one to ask the questions and the other to observe/take notes.

High quality recording equipment, especially a good quality external stereo microphone

45

Page 46: Qualitative Research-  What it is and when to use it

ANALYSIS Examine one question at a time Consider the words Consider the context Consider the internal consistency Consider the specificity of responses Find the big ideas Consider the purpose of the report

46

Page 47: Qualitative Research-  What it is and when to use it

ADVANTAGES OF FOCUS GROUPS Socially oriented- real-life data in a social

environment Flexibility- format allows the moderator to

probe High face validity Low cost (25% - 50% less) Fast results Enable the researcher to increase the sample

size of qualitative studies

47

Page 48: Qualitative Research-  What it is and when to use it

LIMITATIONS OF FOCUS GROUPS Researcher has less control in the group

interview as compared to the individual interview.

Data are more difficult to analyze. Moderators require special skills. Each focus group has unique characteristics. Groups are difficult to assemble. Environment must be conducive to conversation.

LEVELS OF CODING(FOR QUALITATIVE DATA)

OpenBreak down, compare, and categorize

data Axial

Make connections between categories after open coding

SelectiveSelect the core category, relate it to other

categories and confirm and explain those relationships

Page 53: Qualitative Research-  What it is and when to use it

COMPUTER ASSISTED/AIDED QUALITATIVE DATA ANALYSIS (CAQDAS) An ‘indispensable tool for storage retrieval

and manipulation of the text’ (Kelle, 1995). Allows the researcher to sort the data into

easily accessible categories to enable quick retrieval of data

Comparison of segments Refinement and development of codes Examples include NVivo, Atlas, Ethnograph,

and Hypersoft

53

Page 54: Qualitative Research-  What it is and when to use it

WHAT DOES CAQDAS ACTUALLY DO?

Aids mechanical data management techniques such as:

Cutting and pasting into codes Creating subcategories Notes in the margin

54

Page 55: Qualitative Research-  What it is and when to use it

ADDITIONAL USES OF CAQDAS Atlas also allows the storage of audio

recordings and the scanning of pictures and handwritten notes to be used as data.

Hypersoft strives to avoid decontexualisation of data through hyperlinks.

Use of CD ROM to record research which could provide the opportunity for multiple readings of the text.

55

Page 56: Qualitative Research-  What it is and when to use it

DEBATES SURROUNDING CAQDAS The central analytic task in qualitative

research – understanding the meaning of text cannot be computerized. Using CAQDAS is no substitute for thinking hard about the meaning of data.

Only the more mechanical task of data management can be aided by a computer.

Use of software package reflects choices of the researcher.

56

Page 57: Qualitative Research-  What it is and when to use it

IN SUMMARY

Choose software to fit research not research to fit software!!

Overall CAQDAS tends to be used as tool for intelligent management of research data.

METHODS OF EVALUATING QUALITATIVE RESEARCH Developing standards of quality Lincoln and Guba’s classic work shed light on

how to assess truth in a qualitative report Offered four alternate tests of quality that

reflect the assumptions of the qualitative paradigm: Credibility Dependability Transferability Confirmability

Page 59: Qualitative Research-  What it is and when to use it

LINCOLN AND GUBA’S ‘NATURALISTIC’ CRITERIAAspect Scientific Term Naturalistic TermTruth value Internal validity CredibilityApplicability External validity or

generalizability Transferability

Consistency Reliability DependabilityNeutrality Objectivity Confirmability

Page 60: Qualitative Research-  What it is and when to use it

60

ALTERNATE TESTS OF QUALITYCredibility refers to accuracy Description must be plausible and recognized

by participants

Enhanced by: Prolonged time in the field repeatedly

observing and interacting with participants Using different data sources, methods, data

type Conducting member checks

Involving other investigators in the study

Page 61: Qualitative Research-  What it is and when to use it

61

ALTERNATE TESTS OF QUALITYDependability refers to the stability and

trackability of the changes in data over time and conditions

Want to determine the extent to which another researcher with similar training and rapport with participants would make the same observations

This is determined by an audit trail Involves auditing research process,

documenting all the raw data generated, and assessing method of data analysis

Page 62: Qualitative Research-  What it is and when to use it

62

ALTERNATE TESTS OF QUALITYTransferability refers to the generalizability

of the study findings to other settings, populations, and contexts

Report must provide sufficient detail so that readers can assess this

Lack of transferability is viewed as a weakness of qualitative methods

Page 63: Qualitative Research-  What it is and when to use it

6-63

ALTERNATE TESTS OF QUALITYConfirmability refers to the objectivity of the

data

Would another researcher agree about the meanings emerging from the data?

An audit trail is used in which the researcher explains how personal biases may have come into play

Page 64: Qualitative Research-  What it is and when to use it

64

CONTEMPORARY STANDARDS OF QUALITY Diverse inquiry communities Positionality Community Voice Critical subjectivity Reciprocity Sacredness of the research relationship Sharing privileges

Page 65: Qualitative Research-  What it is and when to use it

QUALITATIVE RESEARCH“One of the opportunities --- and challenges -- posed by qualitative approaches is to regard our fellow human beings as people instead of subjects, and to regard ourselves as humans who conduct our research among rather than on them.”

Wolcott, H.F. (1990). Writing up qualitative research. Qualitative Research Methods Series, Vol. 20. Newberry Park: Sage.

65

Page 66: Qualitative Research-  What it is and when to use it

CRITERIA FOR EVALUATINGQUALITATIVE RESEARCH Is the research significant? Is there new or

unique information that is added to the work of others?

Are the methods appropriate for the question?

Are informants appropriate to inform study questions?

Was data collection systematic? Adequate? Is reference made to accepted procedures for

analysis? Was a systematic inductive approach used?

66

Page 67: Qualitative Research-  What it is and when to use it

CRITERIA FOR EVALUATINGQUALITATIVE RESEARCH (CONTINUED) Is there adequate discussion of how the

themes, concepts and categories were derived from the data?

Are the researcher’s conceptualizations true to the data? Are findings presented within a context? Is the reader able to understand the essence of the experience from the report of findings?

Is the credibility of the findings addressed? Do the conclusions reflect study findings?

67

Page 68: Qualitative Research-  What it is and when to use it

6-68

ADVANTAGES AND LIMITATIONS OF QUALITATIVE RESEARCH Focus on the whole of the human experience

and the meanings ascribed to them by participants

They provide the researcher with deep insights that would not be possible using quantitative methods

The major strength of qualitative work is the validity of the data it produces

Participants true reality is likely to be reflected

Major limitation is its perceived lack of objectivity and generalizability

Researchers become the research tools and may lack objectivity
