Qualitative research has tremendous potential for
breaking new ground in gerontological research. QUALOG, a qualitative
analysis program using logic programming and computer support, has been
developed. This article describes how QUALOG was utilized to analyze data from
a qualitative study of older adult learners.

Qualitative research has a useful role to play in helping scholars understand adult behavior from the perspective of subjects. Brookfield (1983) and Rockhill (1982), in fact, urge educators of adults to look carefully at the appropriateness of research methodology because quantitative research frequently is overused or misused.
Researchers using qualitative methodologies approach data
collection and analysis inductively. Interviews and/or participant observations
can be used to inductively build theory. Such theory is grounded in the
subject's observed behavior and words rather than in a deductive testing of an
a priori hypothesis or theory. For example, Fingeret (1983) used in-depth, unstructured
interviewing and participant observations to demonstrate the importance of
social networks to illiterate adults. Her initial work led to some working
theories about the literacy movement in the United States (Fingeret, 1984).
The popularity of qualitative educational research
methodology is both recent and growing, especially if one looks beyond the
interviewing efforts of people like Houle (1961) and Tough (1967, 1979).
Page 418
One of the first clarion calls for such qualitative
approaches to research was made by Mezirow (1971). He urged educators of adults
to utilize Glaser and Strauss' (1967) "grounded theory" methodology
in furthering the development of a theory of practice for the field. Subsequent
work by Mezirow and his colleagues (Mezirow, Darkenwald, & Knox, 1975; Darkenwald,
1980) provided some useful models for related research. For example, Jones and
Charnley (1978) utilized a grounded theory approach to assess the impact of
adult literacy. Long (1983) noted that a total of 13 grounded theory studies
were reported at the Adult Education Research Conference between 1977 and 1980.
Rubenson (1982) also notes the popularity and importance of grounded theory approaches.
Other qualitative approaches have been used, too. Warren
(1982) describes the use of the written life history as a prime research tool
for adult educators. Gibbons and colleagues (1980) studied the biographies of
20 top achievers for self-directed characteristics. Brookfield (1981) combined
an open-ended interviewing approach with grounded theory analysis techniques to
determine the learning activities, attitudes, and networks of 25 successful
independent learners in England. Hiemstra (1982) reported on the case study method
combined with grounded theory in a longitudinal study of 30 older adults. This
latter study serves as a focal point for this article in that new data were
gathered and new qualitative analyses undertaken.
More specifically, this article demonstrates how a qualitative research tool can be used to examine the learning behavior of older adults. Use of such techniques as in-depth interviews allows interviewees to define and clarify a perception of themselves as successful lifelong learners. The researcher goes to the subjects to gather and examine information with a minimum of predetermined theoretical expectations. This technique, however, presents some difficulties for the researcher when organizing and analyzing the volume of data collected. A common method of organizing data for analysis involves the use of multiple copies of field notes which are cut and placed in file folders according to categories determined by a researcher's review of the data. Problems can easily arise when using such a system. Required researcher time and expense can be immense. The problems of managing large amounts of data efficiently, and the possibility of missing important insights through improper filing or coding also exist.
The advent of computer-assisted data analysis has helped to
resolve some of these problems. Computers have a tremendous
Page 419
potential and have been used extensively as a tool for quantitative data analysis. Their extension into qualitative analysis is a predictable outgrowth of such benefits as speed, storage potential, and multiple variable manipulations. Conrad and Reinharz (1984) provide some insights into the use of computers for qualitative research. However, because the researcher must stay intimately involved in qualitative research in terms of coding, recoding, memo writing, and so on, the computer remains simply a tool for facilitating analysis efforts. It is the researcher's use of this tool that determines the degree to which computer-assisted data analysis is appropriate and effective in qualitative research.
A computer-assisted, qualitative data analysis scheme using
logic programming has been developed at Syracuse University. The purpose of
this article is to describe this scheme, entitled "QUALOG" (Hiemstra,
1986; Shelly & Sibert, 1985), and to provide some incentive for increased
use of qualitative inquiries and computer-assisted analysis in gerontological
research.
QUALOG
Qualitative data analysis involves various activities used to organize, interpret, synthesize, conceptualize, and report information. The researcher examines data for recurring themes, word patterns, study foci, relationships among categories, evolving themes, and even hypothesis-testing opportunities. Frequently, qualitative analysis can require considerable time, resources, and painstaking manipulation of small bits of data.
The developers of QUALOG have produced a series of computer programs designed to aid in the analysis efforts. A computer is used to keep track of a study's evolution, including such mechanical tasks as organizing the data, coding information, writing memoranda, and interpreting data. The interpretation phase can be quite powerful, including such functions as tabulating the number of times various codes are used, comparing information with different coding labels for commonalities, and even the testing of tentative hypotheses through a sophisticated query process. The availability of a recoding system enables researchers to refine queries and hypothesis testing as the analysis evolves.
QUALOG is based on a logic programming system that uses logical assertions and a theorem-proving capability to establish the existence or nonexistence of one or more results that satisfy conditions the researcher establishes in what is called an answer template. The template is designed by the researcher thinking about possible or
Page 420
probable relationships among terms and then stating such
associations in natural words or terms. Results arise as a by-product of the
proof required for the theorem-proving activity. LOGLISP (Robinson &
Sibert, 1981), the programming system in which QUALOG is written, integrates
logic programming with LISP (McCarthy, 1960; McCarthy, Abrahams, Edwards, Hart,
& Leven, 1965; Meehan, 1979), primarily a language used for symbolic
computations. The combination provides a flexibility required to work directly
with symbolic information, prose, field notes, subsequent memoranda, and
evolving relationships within the data.
To use QUALOG the researcher enters data into separate files
for later manipulation. There currently are two mechanisms for entering data,
such as interviews, field notes, observational information, and memoranda. One
method involves the use of an IBM VM/CMS (Virtual Machine/Conversational Monitor
System) or a DEC (Digital Equipment Corporation) VAX main frame computer with
the VMS (Virtual Memory System) file editor or word-processing entry program.
The individual entering data uses an on-line terminal or modem-connected
keyboard to "type" in the information. Data from magnetic tape,
floppy disk, or transcribed audiotape can be used, but they must be entered as
a main frame file through appropriate communication devices for final
preparation. Another method is to use an optical character reader, which
translates typed or printed material into a digitalized data file.
A word-processing program on the main frame permits
subsequent corrections, deletions, or additions. Data are next formatted so
that unique (sequential) numbers are given to each line of, say, 50 to 60
characters long. This feature is necessary so that any section of text can be
easily referenced. Once the formatted data are available, the researcher
manually codes all information (usually by marking off appropriate sections of data
from a printed version of any formatted files and assigning coding-category
labels). The "codes" are then entered through QUALOG'S coding
program. A memo-writing function also is available to record the researcher's
notes and ideas that evolve throughout the analysis effort. All inputted
information is referenced chronologically by coding category and by data
groups.
Finally, the researcher can retrieve data in a variety of
formats based on the coded information. This step is used to deduce instances where
data confirm or disconfirm formally expressed queries about any coded
information, text in data files, and any other information associated with the
data relevant to emerging hypotheses. Storing, revising, rerunning queries, and
retrieving
Page 421
memoranda both chronologically and by coding categories are
the mechanisms available to test hypotheses and generate theory.
USING QUALOG FOR DATA ANALYSIS
Baseline Study
An impetus for the data-analysis effort described here was a
longitudinal study begun in 1975 by the senior author (Hiemstra, 1982). Over a
two-month period he interviewed, observed, and gathered documents from 30 older
adults in Iowa and Nebraska. Informal follow-up to this initial study period
took place in 1976-1979 via letters, telephone calls, and visits with several
subjects. A more formal open-ended questionnaire in 1983 completed the study's
initial phase.
The study's purpose was to examine the lives, thoughts, and
words of selected older adults who were by reputation successful adult learners.
Subjects were asked to participate based on the recommendations of professional
adult educators or gerontologists. Formal higher education achievement or
current learning activities were not included as criteria for participation.
The intention was to develop a "grounded theory" about success of the
lifelong learner.
Relevant demographic information from the initial group of
30 participants included the following: 40% were males and 60% were females;
90% had an average or above average income; 86% lived in apartments or their
own homes; 83% were married and living with their spouses or were widowed; 33%
were college graduates; and 36% had had careers teaching in public schools.
A number of significant themes emerged from the data
analysis completed in 1982; the analysis involved developing a coding scheme,
hand sorting data according to several developed codes, and feedback by
colleagues as the information emerged. Regarding an overall category labeled
"health," the subjects appeared to have a high level of mental
alertness, generally enjoyed life, were well-groomed, and had a fairly
significant level of relaxation. Another category evolved and was called
"A Personal Involvement in Learning." The subjects were for the most
part active readers, engaged in study projects, and pursued a wide range of
learning activities. All subjects had achieved educational backgrounds in
colleges, normal schools, or specialized training beyond high school.
Many of the subjects were actively involved in writing
projects. Several had published books and professional articles, were writing
poetry, or were conducting personal research of one kind or another.
Page 422
Finally, a majority of participants viewed themselves as
successful older adult learners. They identified keeping active, being curious,
self-reliance, and a strong parental influence as major factors fostering their
success as adult learners. Most also stated that they practiced some form of
meditation or self-reflection as a source of inner strength and as a resource
for coping with life's vicissitudes.
The subjects were all known to be involved in church,
family, volunteer activities, and/or educational pursuits. The subjects all
lived at home and were, or had been, married. A teaching background also was
prevalent in either the subjects themselves or within their families.
This brief summary of the initial analysis of data is
presented as a framework from which the present phase finds its impetus and
direction. In the current phase six new subjects were studied. Each junior
author carried out a case study of two subjects selected because by reputation
and activity they resembled subjects in the earlier study. Information from
four participants in the initial study also were included to provide a base of
10 successful learners, all over 70 years of age. This group comprises the database
for a present analysis of information by the QUALOG computer-assisted data
analysis scheme.
Computer-Assisted Data-Analysis Effort
Data analysis actually began before the researchers gathered
information on any new subjects. Discussion and dialogue between the four
researchers was structured by the initial study's analysis efforts. Newly
gathered information was reviewed and reflected upon during subsequent group
sessions. Progressing through the mechanical processes of QUALOG, such as
scanning, transcribing, and creation of working (T) and analyzing (I) files,
the need to collaborate on developing comprehensive lists of codes and subcodes
became apparent.
The development of codes and subcodes can be a complicated
process. There must be agreement on definitions of code words and the
connotation and context in which any code will be applied to the data must be
clarified. Researchers using qualitative techniques rely on experience and
sensitivity to emerging themes discernible in the data to assist in that
process. Approximately eight hours of group sessions were required for
clarification and acceptance of the final list. Main codes were developed by
identifying a repetitive theme within one or more interviews. Subcodes were
used to further clarify, describe, and/or narrow the theme. Strength of the
main
Page 423
codes lay in the number of times a theme could be identified throughout the interviews.
The need for clearly defined main codes is clear. For
example, when coding a theme such as "retirement," subjects' words,
phrases, or paragraphs were placed in this code when that word itself was used,
when a related view was expressed, or a related attitude described. Subcodes
augment or clarify the main code. For example, "positive" or
"negative," "self" or "family," could be used to provide
further description of "retirement."
Another main code example, "inner resources,"
became an umbrella for "serenity," "inner strength," or
spirituality." Subcodes used for clarification in this instance could
include "self," "spouse," or "family." It was
also possible to link two main codes such as "retirement" with
"inner resources," if the data (an interviewee's own words) indicated
such a linkage could be made or was being made during an interview.
Two additional commands within QUALOG were particularly
useful in the next step of data analysis. After the raw data had been coded, it
was possible to begin generating working hypotheses or formalized linkages
between anticipated or suspected relationships. The end purpose of a grounded
theory is to explicate human behavior. Since the main and subcodes are a "shorthand"
for subjects' words, behaviors, and attitudes, working hypotheses are a method
of blending researchers' summaries of what was observed with subjects' actual
words and behaviors to develop a theory of human behavior.
The first of these additional commands,
"fatcodes," rapidly lists the number of times a main code is used.
This command can be varied to select one particular interview or used across
all interviews. For example, in one particular interview "retirement"
was mentioned 13 times, sometimes when the interviewee was describing his
retirement process or attitudes about being retired, and other times when
talking about seemingly unrelated areas. Across all 10 interviews the term was
mentioned nearly 100 times.
The second command, "pcodes," is valuable in that
it identifies actual line numbers in the text where a specific main code or
subcode is mentioned by a subject. This information enables a researcher to
return to the original copy of the interview and by referencing the line
numbers review actual words as they were used by a subject. In the above
example, it would be possible to read as many lines as desired above or below
each of the 13 times retirement is mentioned. in the above. example to obtain
some ideas regarding the context in which an interviewee brought up the term.
It also
Page 424
would be possible to quickly scan any text for all 10
interviewees where "retirement" is mentioned only if it is in
relationship to or in context with a discussion about spouse or family. Thus,
working hypotheses can be generated, analyzed initially, and refined until some
level of saturation is reached. Recoding of data is always possible to assist
in the refinement process.
Memo writing is also facilitated by the use of
"fatcodes" and "pcodes." As new insights, themes, ideas or
methodological issues occur to researchers, summary notes or memos can be added
to the overall base. In other words, memo writing assists with recording, organizing,
and storing the researcher's thoughts and ideas as data analysis proceeds.
QUALOG also facilitates collaboration and a sharing of ideas among research
group members as a printout of all memos is an integral program feature,
thereby fostering clarification and group communication.
The QUALOG program is a useful and powerful tool for data
analysis in qualitative research. Generation and interpretation of field note
themes into main and subcodes assists in the development of working hypotheses.
These hypotheses become the basis for further research analysis and theory
development, which, of course, remain the researcher's task.
CONCLUSIONS
QUALOG is a valuable tool for sorting, storing, and
organizing vast amounts of data usually collected in qualitative research. The
manual cut-and-paste approach to coding information and data analysis is
transferred by means of this computer program to an efficient, easily
retrievable system. The program allows for multiple researcher manipulations of
data into manageable units of information. A further benefit of QUALOG is that
associations, themes, and trends encompassing the inductive research process
are easily discernible. Memos also are an integral part of the QUALOG data
collection process; they are easily stored and retrieved to serve as additional
sources of data insights and reflections.
In this particular project, group collaboration was useful
for developing codes, themes, and hypotheses. Mutual support and sharing of
information and ideas was also a singular advantage to the researchers in
learning techniques and intricacies of the QUALOG program.
As with any new computer system, there are limitations to
its utility. Of particular caution to a neophyte user of QUALOG is the
potential that interest in any mechanical processes of a computer
Page 425
program might distract from the research focus. In addition,
researchers must be prepared to expend large blocks of time learning this
sophisticated computer-assisted data-analysis system. The state of the art at
present is only as good as the researcher's understanding and ability to use
and apply QUALOG to raw data. Frustration is inevitable when the computer
system is down, data are inadvertently lost, or inappropriate commands result
in useless information. Nevertheless, the program's strengths and usefulness
can far outweigh its limitations.
