HD FS 503 Research Methods in HD FS Qualitative Research Methods Susan Hegland & Mary Winter April 8, 2002 1 Tonight Review: Threats to Validity Qualitative Designs • Characteristics • Scientific rigor • Applications 2 Qualitative Research • All researchers use qualitative methods • Quantitative researchers usually assign numbers to qualitative responses • Often numbers are category names • gender • quality, not quantity • but we correlate as if it is a quantity 3 Qualitative Methods • Goal: “thick description” of phenomenon • Involve data gathering through a variety of techniques • Goal not to quantify whatever is being observed • Data reduction: winnowing into themes or concepts Art: the elimination of the unnecessary Picasso 4 No one set of accepted rules for qualitative research • Some reject all quantitative methods and numerical data reduction methods • Some perceive quantitative research as reflecting historically male-dominated power systems • Others see value in both verbal and quantitative data reduction techniques • Require similar levels of rigor or trustworthiness in data 5 Anthropological research Etic view • Sees the world as an independent observer sees it • “cloud of gnats” from the observer’s view Emic view • Sees and understands the world as it appears and is understood by those being studied • cloud of gnats from the gnat’s view 6 Ethnography • Traditionally, an ethnography defines a culture • May be the culture of a classroom, village, neighborhood, organization, agency • Ethnographer observes, interviews, reads records • Often participant observation 7 Participant Observers • Live in the community • Meet day needs the way community residents do • Writes copious notes, • then organizes them • Memory assists the ethnographic organization 8 Participant observation • • • • Ideally, participate in what you are study Living in the community Studying a human services agency Classics: • Children of Sanchez • Tally’s Corner • Five Families • Among Schoolchildren • Mostly books 9 In-depth, open-ended interviews • Coded for content analysis • Accompanied by member checks or focus groups to check perceptions • Used by Mary Jane Brotherson & Harvey Joanning • Begin with “Grand tour question” • Follow with mini-tour questions 10 Methods not necessarily qualitative • Field research • can be quantitative or qualitative • Unobtrusive research • can be quantitative or qualitative • Observation research 11 General Issues for Observers • • • • • Observer, or Participant, or Observer-as-participant, or Participant as observer? Ethical considerations: Should you tell those whom you are observing what you are doing? 12 Informants, not respondents Beware of the first native on the beach • May have a hidden agenda • May be seeking approval of outsider: says what you want to hear! Check with other informants • “Why is this person willing to talk with me? • “What point of view is s/he expressing?” 13 Test Reliability, test validity ~ triangulation • Get information about the same phenomena from at least two different sources • Three is better! • Have two different sources of the same information • A State of Mind 14 Three forms of triangulation Data triangulation: • Multiple sources of data across time, space, and persons Investigator triangulation: • Multiple investigators; peer checking Method triangulation: • Multiple methods Denzin (1978) 15 Non-random, nonprobability sampling • • • • • Quota Snowball Deviant cases Typical Purposive 16 Hig h Av era ge Lo w Number of Participants Random sampling: 17 High Average Low Number of Participants Purposive sampling: 18 Saturation • Situation in qualitative research where so many examples of dimension or concept have been gathered • Nothing new expected to be learned from additional examples • No reason to gather more from center of distribution than from extremes 19 Field procedures • Outline questions • See Spradley, The Ethnographic Interview • Have a good idea where you are headed before you begin • Periodically check back, revise procedure 20 Recording data during interview • Tape recorder • Maybe? • Maybe not? • Writing notes? • Definitely: not impolite! • As verbatim as possible (see p. 272) • Lap top? Will it be confidential? • Leave space for analyses • Include reflections 21 Analysis • Patterns; commonalities; “Meaning” • Not enough to string together quotes • Quotes illustrate points • Begins before all data collected • Starts with contact sheet for each interview • Revise questions, member checks, focus groups • Look for negative instances • Audit trail kept • Very time-consuming! 22 Ethical issues • How much do you tell about what you are doing? • Is it fair to observe under false pretenses? • At least, you must debrief afterwords! • Use member checks to review the patterns you see • Do you report illegal behaviors observed? • Consider the social consequences of the study 23 Advantages • • • • Explores new ground Depth of understanding Identifying interrelationships Flexibility 24 Disadvantages • Generalizations not appropriate • Because of limited and selective nature of qualitative evidence • Not probability nor random sampling • Transferability highly speculative! • Hard to get published 25 Comparinq quantitative and qualitative research • “Quantitative research is...quite accurate but limited in scope.” • “[Qualitative research] aims for greater depth but allows less precision.” Sprey, 1995, p. 873 26 Comparing qualitative and quantitative methods Quantitative criteria: Qualitative criteria: • Scientific rigor • Trustworthiness • Internal validity • Credibility or plausibility • External validity • Transferability or fittingness • Test Reliability • Dependability • Objectivity • Confirmability Lincoln, Miles & Huberman 27 Don’t pick the method first! • Pick the question • Then pick the most appropriate method! • Remember: Bad quantitative research is not good qualitative research! and Bad qualitative research is not good quantitative research! 28 For which questions • Would you prefer qualitative methods? • Would you prefer quantitative methods? 29 Example of qualitative analysis: Content analysis 30 Steps in Content Analysis • • • • • From text to table Sorting the table by question Grouping, coding, and labeling responses Checking with a second rater Summarizing the data 31 From Text to Table • Enter text for each response into Word as one paragraph, separated by slashes (/). • For each response, enter ID/Question#/Response. • Table menu: convert text to table • Adjust column width using Autofit command. 32 Sort Table by Question • In the Table Menu, Sort Table by Question#. • Split the Table into separate tables for each question. 33 Group, Code, and Label Responses • Find a second rater to group, code, and label the responses • For each question, group similar responses • Use cut and paste to move similar responses together. • You may choose to split each response into multiple responses • However, beware of losing context! 34 Code your Groupings • In the Table menu, use Insert Column next to responses column. • Give similar responses the same code. • Label each code to represent the content of each group of responses. • Use the Table menu to insert a column; enter labels for each group of responses. 35 Sort Your Codes • In the Table menu, sort by Code, then ID. • Meet with the second rater to review and revise the categories. • In order to demonstrate _____? • Create an index with cross-references • Summarize the results. • Statistics (i.e., percentages) controversial! • You may enter the codes into SPSS • to analyze or to merge with other data sets 36 Practice • Use Table in Handbook • Generate your own codes for the parent statements • Note in right-hand column • Try peer checking • Did you agree? Disagree? • Do you come from similar or different professional backgrounds? 37 Computer Software for Qualitative Analyses • Sample: QSR Nud:ist: in MacKay Lab • Nonnumerical Unstructured Data-Indexing, Searching, & Theorizing • See Scolari.com on the Web • Other software available • Use of software is controversial! • Experts: Damhorst, Littrell 38 QSR NUDIST • Multifunctional software system for qualitative data projects • development, • support, and • management 39 Components of NUDIST • Document system • to store and retrieve text • store references to external data sources • Search function • words, phrases, etc. in text • automatically indexes the result • Index system for data • links categories • explores links with data 40 Indexing with NUDIST • Flexible tree structure for indexing nodes • Free nodes for temporary and nonhierarchical index structures • Index System Search Operators • 18 operators for comparing, relating, contrasting, exploring nodes two, three, or more at a time • Use Boolean co-occurrences (and, or, not) • Use qualitative matrices (p. 315) (Miles & Huberman,1994) 41 On-Campus Resources • HD FS 604 • HPC 580; HPC 680X • Faculty: Brotherson, Greder, Littrell, Bloom, Willis, Blount • not me 42 Application You’ve designed a qualitative study; preliminary reviews claim that you’ve provided no evidence that your “study ” will be more than a novel created in your head: • Stepfamilies involved in blending families • Successful bed-and-breakfast operations • Low income parents in welfare reform • Working parents with children in child care 43 Describe how you will demonstrate: • • • • • Trustworthiness Credibility Transferability or linkability Dependability Confirmability 44
