Philosophical Underpinning Qualitative methodsNot everything that counts can be counted, and not everything than can be counted counts. Einstein
Alternative to Positivism • Human experience is mediated historically, culturally, and linguistically (social constructivism) • • Our perception or experience is one version of reality • • There are knowledgeS, not knowledge
Qualitative Methodology: Guiding principles • • Interest in meaning: • - How do people make sense of the world? • - How do people experience the world? • • Interest in participants’ meanings rather • than researchers’ meanings • • No interest in preconceived variables & • cause-effect relationships • • Aim is to insightfully describe or explain but • not to predict
Criticism of the Scientific Method • Does not allow for new theory development • Treating humans as automata • Experiments eliminate meaning • Reductionist • Ignores social context • Ecological validity
Qualitative data • Non-numerical data, mostly in the form of meanings: • what people say • pictorial e.g. graffiti, film, popular culture • content of songs, stories myths advertisement • uncategorized, unedited recordings of behaviour
Criteria for achieving validity in qualitative research • Trustworthiness and genuineness • Triangulation • Respondent validation • Peer agreement • Independent audit
Practical issues in qualitative research • Can be very time consuming to conduct • Can take more of participants’ time compared to an experimental approach
Participant Observation Qualitative Methods
Observation: Naturalistic, Controlled and Participant • Takes place in natural settings (e.g. hospital, schools) • Observer can be covert or overt • Observations can be systematic but not necessarily so • Researcher engages in variety of activities – participation, documentation, interviewing and reflection • Balance between participation and observation • Notes rich in data are taken
Advantages • Useful when phenomena cannot be replicated in lab • Ecological validity is high but can be not in controlled observation (e.g. Bobo Doll) • Compared to interviews participants far more truthful • Participants less effected by demand characteristics • Can study both humans and non-humans • Clear operational definitions improve validity and reliability • In event sampling, detailed information gathered about frequency, duration and sequence of behaviour
Disadvantages • Questionable reliability and validity (subjective) • Time consuming and labor intensive • Difficult to control variables • Difficult to obtain high inter-observer reliability though training can help • So much complex behaviour means that every event may not be recorded • Cause and effect relationships are not established • Ethics of invasion of privacy and deception with participant observation • Replication difficult
Interviews • Usually face-to-face but also telephone and internet and computer assisted • Most common method of data collection • Easier to arrange than other forms of qualitative data collection • Balance between controlling interview and leaving space for participant to take control
Interviews: Forms • Structured • Pre-determined questions and possible responses • Semi-structured • Mixture of pre-determined questions and more open questions • Unstructured • No questions just general topics • Conversational • No pre-determined questions • Maximum flexibility to follow topic as they develop
Interview: Settings • Individual face-to-face • Most common form • Can enhance rapport but also demand socially acceptable responses • Small Group or Focus Group • Responses build upon each other “synergistic approach” • Email , Telephone Computer assisted • Access to remote populations • Can lessen the demand to provide socially accepted responses
Recording Interviews • Tape recording • Video recording • Note-taking
Transcription of Interviews • Traditional transcripts • Word only • Quick and easy • Subtle meanings may be lost • Post-Modern transcripts • Words plus all aspects of non-verbal communication e.g. tone, pauses, expression posture • Data rich but time consuming and inter-rater reliability an issue
Interviews: Advantages • A range of techniques can be employed including open and closed questions • Data form structured interviews can be quantified to aid analysis • Rich think data
Interviews: Disadvantages • Requires time & effort • As it is a self-report method it relies on the ability to describe own behavior/experiences • Remaining issues of reliability and validity
Verbal Protocol • Verbal protocols – recordings of what people say when carrying out a task under instructions to verbalise all thoughts. • E.g. administering emergency care in a hospital • Used most in problem solving tasks to provide extra information about strategies etc
Verbal Protocol: Advantages • Useful for the participant to verbalize what it is they are doing • Provides a spot analysis of a particular more effectively than an interview
Verbal Protocol: Disadvantages • Participants may not include vital information • Participants need training and practice • Verbalizing my hinder the task being performed especially for those not adept at multi-tasking or who are natural communicators
Content Analysis • Decide how categories will be derived (from data, existing research, or theory) • Establish set of categories / codes from textual data (questionnaires, interviews, newspapers, books, advertisements) • Establish units of analysis (words, sentences, • themes) • Count the number of instances in the data
Content Analysis: Advantages • Unobtrusive therefore no demand characteristic • Easy to replicate as document permanent • Provides longitudinal data • Inter-rater Reliability high – Precisely defined categories –Well trained coders
Content Analysis: Disadvantages • Experimenter effects: Imposing conceptual framework on data: – Data ‘forced’ into analytic categories – Does not take account of meanings/experiences as relevant for participants – Variability and context dependence of meaning neglected • Documentation limited or not available • Cause and effect (chicken and egg question i.e. Do documents reflect social world or do documents cause the social world?
Case Studies • an intensive description and analysis of an individual or related group • Research method originated in clinical medicine and takes an idiographic approach • In-depth investigation of experiences to identify interactions and influences on psychological processes • May consist of a case history (background) interviews, observation and questionnaires and may take place over a long period of time
Case Studies: Advantages • Rich source of in-depth data that other methods might overlook • Effective in studying atypical behaviour i.e. Genie • High ecological validity
Case Studies: Disadvantages • Difficult to generalize • Time consuming • Can lose objectivity by getting to know the participant too well • Difficulty in establishing case and effect relationships • Difficult to replicate
Famous Case Studies • Phineas Gage • Anna O, The Rat Man and Little Hans • Three Faces of Eve • Genie • HM • Sperry’s Split Brain patients • Kitty Genovese
Survey and Questionnaires • A written means of collecting data that does not require the presence of he researcher • A widely used form of data collection in the social sciences • Excellent for investigating beliefs and attitudes characteristic of a respondent, such as attitudes, preferences, interests, values, or personality.
Survey and Questionnaires: Likert Scale • Opinion Surveys: e.g. Likert attitude scales • Strongly disagree • Disagree • Neither agree nor disagree • Agree • Strongly Agree • Highly replicable but biased to illicit socially acceptable answers
Survey and Questionnaires: Psychological Tests • Psychological tests: personality and IQ tests. Items are standardized and tested to ensure reliability and validity • Highly replicable and easy to score • Standardized allowing comparisons between individuals
What specific methods can be used to establish the validity of a qualitative analysis? • Inter-rater reliability • Triangulation - of sources (people, places, times) - of investigators - of methods - of theoretical approaches 4. Participant feedback/respondent validation 5. ‘Paper trail’ + making raw data available + audit
Sampling • Selecting participants from a target population • If the sample is representative, generalizations can be made • Ideal size difficult to determine
Sampling: Types Random • Every potential participant has an equal chance of being selected + best chance of an unbiased representative sample - the larger the target population the harder it is to obtain a random sample
Sampling: Types Stratified • Dividing the population into sub categories and ensuring that your sample has the same proportions of these strata + ensures that sample is representative - time consuming
Sampling: Types Opportunity • Selecting participants that are available at the time + quick and convenient • Unrepresentative sample as a bias may exist in group that is selected • a bias may be introduced by the researcher who is selecting participants
