Strengths of Qualitative Strengths of Qualitative Research:Research:•Qualitative research methods are appropriate for particular types of research. They can convey a richness and intensity of detail in a way that quantitative research can not.•Qualitative research methods allow for much more detailed investigation of issues. When description is the aim, qualitative methods provide a vivid picture of a phenomena.

Strengths of Qualitative Strengths of Qualitative Research:Research:•More and more recognition is being given to the individual in the process, not just the observable effect of 'treatment' upon a 'patient,' particularly in studies that involve health practices (such as investigating addiction, obesity, etc.)•Qualitative methods such as semi-structured interviews, case studies and narrative can ultimately reveal more about the effectiveness (or otherwise) of a form of therapy on an individual.

Limited Generalizability:Limited Generalizability:•One significant limitation of One significant limitation of qualitative research involves the qualitative research involves the limited ability to generalize results to limited ability to generalize results to other populations. other populations. •Because qualitative research is Because qualitative research is oftenoften exploratory and often tailored exploratory and often tailored to the needs of one population to the needs of one population (as (as when a researcher adapts an when a researcher adapts an interview question to a participant's interview question to a participant's prior knowledge, or when case-study prior knowledge, or when case-study analysis is specific to the person or analysis is specific to the person or situation under study)situation under study), it is difficult , it is difficult to extrapolate findings to more to extrapolate findings to more broad populations or to draw general broad populations or to draw general or far-reaching conclusions from the or far-reaching conclusions from the findings of a qualitative study.findings of a qualitative study.
