Question

Tell whether the following statement is true or false:

The paradigm most often associated with MM research is pragmatism.

Answer

True

The paradigm most often associated with MM research is pragmatism, which has as a major tenet “the dictatorship of the research question.”

Question

Tell whether the statement is true or false:

Sequential designs involve both strands occurring in one simultaneous phase.

Copyright © 2017 Wolters Kluwer Health | Lippincott Williams & Wilkins

Answer

False

Concurrent designs (both strands occurring in one simultaneous phase); sequential designs (one strand occurring prior to and informing the second strand)

Copyright © 2017 Wolters Kluwer Health | Lippincott Williams & Wilkins

Sequencing

  • Concurrent designs: both strands occurring in one simultaneous phase
  • Sequential designs: one strand occurring prior to and informing the second strand

Copyright © 2017 Wolters Kluwer Health | Lippincott Williams & Wilkins

Notations

  • All capital letters for the dominant strand
  • All lowercase letters for the nondominant strand and sequence
  • An arrow is used for sequential designs.
  • A “+” is used for concurrent designs.
  • Parentheses can be used to show an embedded structure.

Sampling Strategies

  • Identical: Same participants are in both strands.
  • Nested: Some of the participants from one strand are in the other strand.
  • Parallel: Participants are either in one strand or the other but drawn from a similar population.
  • Multilevel: Participants are not the same and are drawn from different populations at different levels in a hierarchy.

Copyright © 2017 Wolters Kluwer Health | Lippincott Williams & Wilkins

Answer

False

Data collection in MM research can involve all methods of structured and unstructured data.

Data Analysis

  • Integration of the strands
  • Meta-inferences
  • Interpretive level after separate analyses have been completed
  • Focus
  • Congruence
  • Complementarity

Data Conversion

  • Qualitizing
  • Quantitizing
  • Meta-matrices

Integrity

  • Inference quality: the believability and accuracy of inductively and deductively derived conclusions
  • Inference transferability: the degree to which conclusions can be applied to other similar people or contexts
  • Integrative framework for inference quality:
  • Design quality
  • Interpretive rigor
