Critical incident technique and explicitation interviewing in studies of information behavior

Abstract

This article discusses two related techniques, critical incident technique (CIT) and explicitation, which are used in a variety of social science research settings, and critically reviews their application to studies of information behavior. The current application of both techniques is compared with Flanagan's early guidelines on the CIT and is discussed in relation to recent experience in the use of (1) the CIT in the JUSTEIS and VIVOS projects and (2) explicitation in projects concerned with text entering on interactive Web sites. The JUSTEIS project identifies trends, and reasons for those trends, in the uptake and use of electronic information services in higher education in the United Kingdom; this article examines experience gained over the first two cycles—1999 to 2000 and 2000 to 2001. The VIVOS project evaluated virtual health library services. Comparison of the experiences gained on the various projects suggests that critical incident methods could usefully be extended and enriched by some explicitation methods, to elicit the degree of evocation required for current and future studies of Internet use.
