INTRODUCTIONAlmost two decades ago, at the first workshop/technical review on qualitative research methods and ethnography sponsored by the National Institute on Drug Abuse (NIDA), Siegal (1977, p. 79) remarked that despite the existence of numerous excellent qualitative studies on drug
DEFINING QUALITATIVE RESEARCH METHODS
Feldman and Aldrich (1990) date the beginnings of modem qualitative research on drugs to DeQuincey's "Confessions of an English Opium Eater," published in 1822, in which the author took on the role of participant observer among eminent addicts and recorded his observations.Since that time, qualitative research methods have become more systematically defined in the fields of anthropology and sociology (Agar 1980(Agar , 1986Bernard 1988;Denzin 1970Denzin , 1989Glaser and Strauss 1967;Naroll and Cohen 1973; Pelto 1973, 1978;Strauss and Corbin 1990;Vidich and Stanford 1994; Schoepfle 1987a, 1987b).Appropriately applied, qualitative research methods are neither soft science nor the mere journalistic reporting of values, beliefs, and behaviors. Moreover, through their capacity to expose the hidden worlds of drug users and those close to them in their holistic contexts, qualitative and quantitative methods can complement one another.As Denzin and Lincoln (1994b) note, the word "qualitative" implies an emphasis on process and an indepth understanding of perceived meanings, interpretations, and behaviors, in contrast with the measurement of the quantity, frequency, or even intensity of some externally defined variables. Since qualitative methods have different meaning for different people-depending on a person's intellectual background, research problem, and theoretical interests-it is worthwhile to examine several definitions.According to Denzin and Lincoln (1994b, p. 2 Strauss and Corbin (1990, pp. 17-18) offer an even broader definition of qualitative methods in the course of developing the methodology of grounded theory: "By qualitative research we mean any kind of research that produces findings not arrived at by means of statistical procedures or other means of quantification." Strauss and Corbin (1990) note, however, that some researchers employ qualitative interviewing techniques to gather textual data that are subsequently coded and analyzed statistically; in effect, they quantify qualitative data. Other qualitative metbodologists (Bernard 1988;Trotter and Potter 1993;Weller and Romney 1988) employ systematic interviewing techniques, such as triad sorting, to produce data that are analyzed quantitatively.The results of such analyses generate an understanding of cognitive categories, or how people perceive the relationship among categories in some domain, such as HIV risk behaviors.Traditionally, the process of describing and analyzing how people perceive the world and their behaviors has been the goal of professional ethnographers trained in anthropology and sociology.While ethnography is often equated with the practice of qualitative methodologies (Brooks 1994;Werner and Schoepfle 1987a...
