Account Investigation in Damage Research

Presentation Transcript

  1. Narrative Analysis in Injury Research Thomas Songer, PhD University of Pittsburgh This injury was due to …….

  2. Aims • Recognize the value of narrative data that accompanies coded data • Provide a framework for exploring narratives • Ultimate Goal: see to better understand circumstances of an injury

  3. Qualitative Data • Data in the form of words, language in the form of extended text • Can be an alternative research strategy • The underlying assumptions, methods, and research procedures of qualitative approaches are often very different from quantitative approaches Thomas DR

  4. Qualitative Research Approaches • Phenomenology • Ethnography • Narrative analysis • Grounded theory • General inductive • Discourse analysis • Case studies Thomas DR

  5. Comparison of descriptive ability:Fx ankle running on base after dark; stepped in pothole Domain Data Type Nature of injury (N) External cause (E) ICD codes (N) STANAG (E) 824.1Fx of ankle--Medial malleolus, open 239Athletics/sports incl PT, other Medical (inpatient) Medical(outpatient) ICD codes (N) 824.1Fx of ankle--Medial malleolus, open Not available Hierarchical taxonomy & narrative text Inj Type = Fracture Body Part = Foot/ ankle Activity = RunningMechanism* = PotholeTime = 2200 hrsOn_Base = YESNarrative: “Jogging on running trail, detoured onto Center St due to mud . . . .” Safety * Derived from narrative

  7. Analytic Approaches • Computerized keyword search using automated coding software • manual keyword search • manual review • create new variables • recategorize data • code into categories • identify summary themes

  8. Developing Categories for Analysis • Initial categories should be determined by the objectives of the research • Specific categories can be developed from the review of the data and the identification of frequent or significant themes, words, circumstances Thomas DR

  9. Data Consistency • Identify a “case definition” or “eligibility criteria” • Go through data several times to check consistency of coding applied to the categories • Consider the use of an independent coder

  10. An Alternative Approach • Analysis of narrative text structure • setting • individuals involved • problem • initiating event • 2nd event • 3rd event • 4th event • resolution

  11. Limitations • No guidelines for what is entered as text • Manual review is time intensive • Purpose of data collection may not mirror underlying needs of injury research

  12. Key Lecture Points • Narrative analysis is another research technique in the injury field. • It is advocated in situations where existing data contain very little information on the circumstances surrounding an injury. • The analytic approaches in narrative analysis are often subjective, and great care must be taken to develop data consistency to support the results of the analysis.
