Managing Data in CAQDAS

Fielding, Nigel & Lee, Ray M. (1998)

Chapter 4 in Fielding & Lee, Computer Analysis and Qualitative Research, pp. 86-118

from COMPUTER ASSISTED QUALITATIVE DATA ANALYSIS SOFTWARE: A PRACTICAL PERSPECTIVE FOR APPLIED RESEARCH, JOSEPH B. BAUGH, ANNE SABER HALLCOM, and MARILYN E. HARRIS Computer assisted qualitative data analysis software (CAQDAS) holds a chequered reputation to date in academia, but can be useful to develop performance metrics in the field of corporate social and environmental responsibility and other areas of contemporary business. Proponents of using CAQDAS cite its ability to save time and effort in data management by extending the ability of the researcher to organize, track and manage data. Opponents decry the lack of rigor and robustness in the resultant analyses. Research reveals that these opinions tend to be divided by “the personal biography and the philosophical stance of the analyst” (Catterall & Maclaran, 1998, p. 207), as well as “age, computer literacy, and experience as a qualitative researcher” (Mangabeira, Lee & Fielding, 2004, p. 170). A more recent article (Atherton & Elsmore 2007) discussed the continuing debate on CAQDAS in qualitative research: The two perspectives both indicate that CAQDAS should be used with care and consideration; in ways that explicitly demonstrate a “fit” between the ethos and philosophical perspective(s) underpinning a research study, on the one hand, and the means of ordering and manipulating the data within CAQDAS on the other. (p. 75) Despite the ongoing literary debate on the merits of CAQDAS, the use of computer-aided qualitative data analysis has become acceptable to most qualitative researchers (Lee & Esterhuizen; Morison & Moir, 1998; Robson, 2002). However, writers advise that researchers avoid the trap of letting the software control the data analysis (Catterall & Maclaran, 1998). Morison and Moir counseled that CAQDAS is merely one tool in the qualitative data analysis toolbox. No tool should replace the researcher's capacity to think through the data and develop his or her emergent conclusions (Atherton & Elsmore, 2007). On the other hand, Morison and Moir among others (e.g., Blank, 2004; Catterall & Maclaran, 1998; Mangabeira et al., 2004) found the use of qualitative data analysis software can also free up significant amounts of time formerly used in data management and encoding allowing the researcher to spend more time in deeper and richer data evaluation. Qualitative research studies to develop performance metrics can create huge amounts of raw data (Miles & Huberman, 1994; Robson, 2002). Organizing, tracking, encoding, and managing the data are not trivial tasks and the effort should not be underestimated by the applied researcher. Two methodologies exist to handle these activities and manage the data during the data analysis phase. The first methodology is a manual process, which must be done at times to avoid missing critical evidence and provide trustworthiness in the process (Malterud, 2001), while the second methodology indicates the use of technology for managing the data and avoid being overwhelmed by the sheer amount of raw data (Lee & Esterhuizen, 2000). It is the experience of the authors that some manual processing must be interspersed with CAQDAS. This provides an intimacy with the data which leads to the drawing of credible and defensible conclusions. Thus, a mixed approach that melds manual and automated data analyses seems most appropriate. A basic approach for applying traditional qualitative research methodologies lies in the ability of CAQDAS to support data reduction through the use of a “provisional start list” (Miles & Huberman, 1994, p. 58) of data codes that are often developed manually from the research question. A rise in the use of CAQDAS for applied research and other nonacademic research fields has been identified (Fielding & Lee, 2002). Since CAQDAS is becoming more prevalent in nonacademic researcher populations and can be useful for developing performance metrics for corporate social and environmental responsibility and solving other complex business issues, it seems prudent at this juncture to discuss how to use the software appropriately rather than rehash the argument for or against using CAQDAS. Selection of and training with an appropriate CAQDAS package can help the researcher manage the mountains of data derived from qualitative research data collection methods (Lee & Esterhuizen, 2000).

Qualitative Interviewing

Patton, Michael Quinn (1980)

Thousand Oaks: Sage Publications, In Michael Quinn Patton, Qualitative Evaluation Methods, pp. 195-263

We interview people to find out from them those things we cannot directly observe. This issue is not whether observational data are more desireable, valid, or meaningful than self-report data. The fact is tahtw e cannot observe everything. We cannot observe felings, thoughts, intentions, behaviors that took place at some previous point in time, situations that preclude the presence of an observer, or how people have organized the world and the meanings they attach to what goes on in the world. We have to ask people questions about those things. Thus, the purpose of interviewing is to allow us to enter into the other person's perspective. Qualitative interviewing begins with the assumption that the perspective of others is meaningful, knowable, and able to be made explicit. We interview to find out what is in and on someone else's mind, to gather their stories. Program evaluation interviews, for example, aim to capture the perspectives of program participants, staff, and others associated with the program. What does the program look and feel like to the people involved? What are their experiences? What thoughts do people knowledgeable about the program have concerning the program? What are their expectations? What changes do participants perceive in themselves as a result of their involvement in the program? It is the responsibility of the evaluator to provide a framework within which people can respond comfortably, accurately, and honestly to these kinds of questions. Evaluations can enhance the use of qualitative data by generating relevant and high quality findings. As Hermann Sudermann said in Es Lebe das Leben I, ‘I know how to listen when clever men are talking. That is the secret of what you8 call my influence.’ Evaluators must learn how to listen when knowledgeable people are talking. That may be the secret of their influence. An evaluator or qualitative or mixed method research interviewer faces the challenge of making it possible for the person being interviewed to bring the interviewer into his or her world. The quality of the information obtained during an interview is largely dependent on the interviewer. This chapter discusses ways of obtaining high-quality information by talking with people who have that information. We’ll be delving into the ‘art of hearing’ (Rubin and Rubin 1995). This chapter presents three different types of interviews. Later sections consider the content of interviews: what questions to ask and how to phrase questions. The chapter ends with a discussion of how to record the responses obtained during interviews. This chapter emphasizes skill and technique as ways of enhancing the quality of interview data, but no less important is a genuine interest in and caring about the perspectives of other people. If what people have to say about the world is generally boring to you, then you will never be a great interviewer. On the other hand, a deep and genuine interest in learning about people is insufficient without disciplined and rigorous inquiry based on skill and technique.

Intercoder Reliability for Validating Conclusions Drawn from Open-Ended Interview Data

Kurasaki, Karen S. (2000)

Field Methods, 12(3): 179-194

Intercoder reliability is a measure of agreement among multiple coders for how they apply codes to text data. Intercoder reliability can be used as a proxy for the validity of constructs that emerge from the data. Popular methods for establishing intercoder reliability involve presenting predetermined text segments to coders. Using this approach, researchers run the risk of altering meanings by lifting text from its original context, or making interpretations about the length of codable text. This article describes a set of procedures that was used to develop and assess intercoder reliability with free-flowing text data, in which the coders themselves determined the length of codable text segments. Discusses procedures for developing and assessing intercoder reliability with free-flowing text.

Entertainment Venue Visiting and Commercial Sex in China

Lin, C. Lieber, E. (2010)

International Journal of Sexual Health

Entertainment venues in China play an important role in the sexually transmitted disease (STD)/HIV epidemic. Most previous studies have focused on sex workers working in entertainment venues, but little is known about their clients. This study investigated the perceptions and behavior of the patrons visiting entertainment venues. Qualitative in-depth interviews were conducted with 30 male market vendors who visited entertainment venues at least once in the past 3 months in an eastern city in China. Information about their risky behavior, attitude toward commercial sex, and STD/HIV prevention approaches was collected. Saunas, karaoke bars, and massage centers are the most frequently visited entertainment venues.

Mixed Methods Research: A Research Paradign Whose Time has Come

Johnson, R. B., & Onwuegbuzie, A. J. (2004)

Educational Researcher, 33(7): 14-26

Positions mixed methods as natural complement to traditional qualitative and quantitative research, to present pragmatism as attractive philosophical for mixed methods research, and provide framework for designing and conducting mixed methods research. In doing this, we briefly review the paradigm “wars” and incompatibility thesis, we show some commonalities between quantitative and qualitative research, we explain the tenets of pragmatism, we explain the fundamental principle of mixed research and how to apply it, we provide specific sets of designs for the two major types of mixed methods research (mixed-model designs and mixed-method designs), and, finally, we explain mixed methods research as following (recursively) an eight-step process.

Barriers to Integrating Quantitative and Qualitative Research

Bryman, A. (2007)

Journal of Mixed Methods Research, 1(1): 8-22

This article is concerned with the possibility that the development of mixed methods research is being hindered by the tendency that has been observed by some researchers for quantitative and qualitative findings either not to be integrated or to be integrated to only a limited extent. It examines findings from 20 interviews with U.K. social researchers, all of whom are practitioners of mixed methods research. From these interviews, a wide variety of possible barriers to integrating mixed methods findings are presented. Challenges to integrating mixed methods data and strategy for writing mixed methods research articles.

What Good is Polarizing Research into Qualitative and Quantitative?

Ercikan, Kadriye & Roth, Wolff-Michael (2006)

Educational Researcher, 352(5), 12-23

The authors argue against a polarization between qualitative and quantitative methods and the associated polarization between “subjective” and “objective” evidence. In doing so, they encourage an understanding of the meaninglessness of such a distinction and the value of taking a more integrated approach. Finally, they map a more “continuous” perspective to addressing the needs of a particular research question and the study design and methodological decisions that follow.
