\n| Interpretivism \/ Constructivism<\/td>\n | Reality is socially constructed and understood through individuals’ meanings and experiences.<\/td>\n | Foundation for phenomenology, narrative research, and most interview-based studies.<\/td>\n<\/tr>\n |
\n| Critical \/ Transformative<\/td>\n | Reality is shaped by power, history, and social structures; research should challenge inequality.<\/td>\n | Underpins critical ethnography, participatory action research, and feminist research.<\/td>\n<\/tr>\n |
\n| Pragmatism<\/td>\n | The research question, not a single worldview, determines the methods used.<\/td>\n | Common foundation for mixed methods research combining qualitative and quantitative data.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n <\/span>Qualitative Research Approaches<\/span><\/h2>\nThe following table summarizes the major approaches used to design a qualitative study. There is often overlap between approaches, and a single study may combine elements of more than one.<\/p>\n \n\n\nApproach<\/strong><\/td>\nPurpose<\/strong><\/td>\nExample<\/strong><\/td>\n<\/tr>\n\n| Phenomenology<\/td>\n | Explores and interprets individuals’ lived experiences of a phenomenon.<\/td>\n | Studying how family members experience a relative’s major surgery.<\/td>\n<\/tr>\n | \n| Grounded theory<\/td>\n | Develops a theory inductively from data, without starting from a hypothesis.<\/td>\n | Investigating why employees leave a company with high attrition and no prior explanatory data.<\/td>\n<\/tr>\n | \n| Ethnography<\/td>\n | Describes a cultural or social group through observation in its natural setting.<\/td>\n | Studying staff behavior and culture in a hospital’s emergency department.<\/td>\n<\/tr>\n | \n| Case study<\/td>\n | Provides an in-depth analysis of a complex issue within a real-life context.<\/td>\n | Examining how one company turned around its sales through a specific marketing strategy.<\/td>\n<\/tr>\n | \n| Narrative research<\/td>\n | Examines personal stories to understand how people construct meaning from experience.<\/td>\n | Collecting life-history interviews to write a biography.<\/td>\n<\/tr>\n | \n| Action research<\/td>\n | Links theory and practice through cycles of collaboration between researchers and participants to drive change.<\/td>\n | Teachers and researchers jointly redesigning a curriculum and evaluating its effects each term.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n <\/span>Qualitative Research Methods<\/span><\/h2>\nQualitative research methods are the specific techniques used to collect data. Researchers often combine more than one method within a single study.<\/p>\n \n\n\nMethod<\/strong><\/td>\nDescription<\/strong><\/td>\nBest Used For<\/strong><\/td>\n<\/tr>\n\n| In-depth or one-on-one interviews<\/td>\n | Conversational, often semi-structured exchanges with open-ended questions, conducted face-to-face or remotely.<\/td>\n | Understanding an individual’s subjective opinions and experiences in detail.<\/td>\n<\/tr>\n | \n| Focus groups<\/td>\n | Guided discussions with around six to ten participants and a moderator.<\/td>\n | Exploring shared opinions on a topic, such as a new product or policy.<\/td>\n<\/tr>\n | \n| Observation<\/td>\n | Recording behaviors, interactions, or settings using the senses, without manipulating variables.<\/td>\n | Studying behavior in natural, real-world settings.<\/td>\n<\/tr>\n | \n| Document study, literature review, or secondary research<\/td>\n | Reviewing existing written materials such as archives, reports, articles, or policy documents.<\/td>\n | Building context, identifying gaps, or analyzing existing texts.<\/td>\n<\/tr>\n | \n| Open-ended surveys<\/a><\/td>\n | Questionnaires that invite written, free-text responses rather than fixed-choice answers.<\/td>\n | Gathering qualitative input from larger or geographically dispersed groups.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n <\/span>Types of Qualitative Research<\/span><\/h2>\nBeyond specific approaches, qualitative studies can also be grouped by their broader purpose:<\/p>\n \n- Exploratory research:<\/strong> Conducted to gain initial insight into a poorly understood topic, such as emerging online learning behaviors.<\/li>\n
- Descriptive research:<\/strong> Provides a detailed account of a phenomenon as it naturally occurs, such as the communication styles used by social media influencers.<\/li>\n
- Interpretive research:<\/strong> Focuses on how people interpret and make sense of their social world, such as how patients understand the idea of \u201ccare\u201d in clinical settings.<\/li>\n
- Evaluative research:<\/strong> Assesses the effectiveness or impact of a program or intervention, such as a community health education initiative.<\/li>\n<\/ul>\n
<\/p>\n <\/span>What Is Longitudinal Qualitative Research?<\/span><\/h2>\nLongitudinal qualitative research collects data from the same participants, or about the same phenomenon, at multiple points in time to study how experiences, perceptions, or behaviors change or develop. It adds a time dimension to standard qualitative approaches such as interviews or case studies.<\/p>\n \n\n\nDesign Type<\/strong><\/td>\nWhat It Tracks<\/strong><\/td>\nExample<\/strong><\/td>\n<\/tr>\n\n| Panel or cohort design<\/td>\n | The same individuals, interviewed repeatedly over time.<\/td>\n | Interviewing the same group of new teachers at the end of years one, three, and five of their careers.<\/td>\n<\/tr>\n | \n| Trend design<\/td>\n | Different but comparable samples studied at different times.<\/td>\n | Conducting focus groups with new students each year to track changing attitudes toward campus services.<\/td>\n<\/tr>\n | \n| Follow-up or retrospective design<\/td>\n | Participants revisited after an initial study to assess later outcomes.<\/td>\n | Re-interviewing patients a year after a treatment program to assess lasting effects.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Longitudinal qualitative research is useful for studying recovery journeys, career or life transitions, and the long-term impact of policies or programs. Key challenges include:<\/p>\n \n- Participant attrition, as some individuals drop out between waves of data collection.<\/li>\n
- Recall bias, when participants reinterpret earlier events in light of later experiences.<\/li>\n
- Maintaining a consistent coding framework across multiple time points while still allowing new themes to emerge.<\/li>\n
- The additional time, funding, and researcher continuity required compared with a single-point study.<\/li>\n<\/ul>\n
