  1. Global PaedSurg Research Training Fellowship Session 5: Data Collection Professor Adesoji Ademuyiwa & Tessa Conception March 29, 2019

  2. Aim • To summarize types of data collection and review methods for collecting data

  3. Objectives • Understand basics of the two main types of of data collection: Quantitative and Qualitative • Review types of quantitative data and benefits of each type • Summarize methods of collecting data

  4. Types of Data Collection • Quantitative • Survey research • Cross-sectional • Longitudinal • Hospital patient data • Retrospective • Prospective • Qualitative • Focus groups • Interviews

  5. Quantitative data

  6. Surveys

  7. Surveys • Other aspects to consider • Population to survey • - Entire population vs part of population (US census vs DHS) • Content of survey • Length of survey

  8. Survey examples (complicated)

  9. Survey examples (simple) Survey examples (simple)

  10. Hospital patient data • Prospective – future sampling • Able to gather specific variables • Better understanding of context • More time consuming • Retrospective – past sampling • Tends to be quicker and cheaper • Limited control of variables • Limited understanding of context

  11. Types of quantitative data • Binomial – yes/no, true/false • Nominal – Color (no order) • Ordinal – Scale of 1 to 10 (has order) • Closed answer: Provide options for answering • Open answer: Participant writes in answer • WARNING: Open answer can be informative but difficult to analyze later on. Open answer questions are great for gathering supplemental information. • Example: Surgical condition explanation in Somaliland

  12. Qualitative data

  13. Interviews • Most common data collection method for qualitative research • Personal approach, typically one-on-one • Interviewer typically leads the discussion Key Informant Interviews (KII) Qualitative in-depth interviews with people who know what is going on in the community. The purpose of key informant interviews is to collect information from a wide range of people—including community leaders, professionals, or residents—who have first hand knowledge about the community. (UCLA Center for Health Policy Research)

  14. Interviews • Structured • Questions are pre-determined • Semi-structured • Some questions are predetermined but interview might change depending on answers • Unstructured • Topic for interview is determined, but the interview is more of a conversation, with no particular agenda

  15. Focus Groups • Group discussion setting. • Limited to 6-10 people (typically) • Moderator is assigned continue discussion. • Members of a group may have something in common.

  16. Methods of data collection

  17. Methods of Data Collection • Paper and pencil • Electronic • RedCap • Microsoft Access • Microscoft Excel/Google Sheets • Audio recording/transcribing • Phone interview • In person interview

  18. Paper data collection Pros: Mobile, easy to use, no need for internet Cons: Can be expensive, data security issues

  19. Electronic data collection RedCap https://www.project-redcap.org/ Pros: Free to non profit organizations, complex survey capable, online and offline options, mobile options Cons: Must be affiliated with organization Microsoft Access Pros: Within Microsoft programs, secure Cons: Can be difficult to learn/manage Microsoft Excel/Google Sheets Pros: Easy to use Cons: Not as secure Open Data Kit (ODK) https://opendatakit.org/ Pros: Free, easy to use Cons:

  20. Data Collectors Things to consider: Training time Travel time Compensation Expertise needed Language and culture barriers
