  • 3.

    Triangulation. Findings from differing research tools will be searched for convergence and participants will be triangulated as well (Stake, 1995).

  • 5.

    Attentive engagement and careful observation. Data collection and analysis will be carefully designed for possible duplication of the study (Creswell, 2003).

  • 6.

    Peer debriefing. Colleagues will debrief the data and results to increase reliability (Creswell, 2003).

  • 7.

    Negative case analysis. Negative cases are used to give a complete picture (Creswell, 2003).

Mixed methods research can play a supportive/informative role with either

quantitative research or qualitative research being the main form of research (Tashakkori

& Teddlie, 1998). This support role helps provide reliability and validity to the overall

study by combining the two methods.

Limitations of a Concurrent Triangulation Design

The limitations of the concurrent data collection model include the difficulty

comparing the results of two analyses using data of different forms. It is possible that one

form of data collection might introduce bias that would confound the results from the

other form of data collected from the same participants. This method may also result in

unequal evidence within the study (Creswell & Clark, 2006).
