Abstract
Abstract The present paper reports results regarding the development and validation of the S.I.E.D.U., an electronic instrument for assessing users’ skills in electronic dictionary searches. The S.I.Ε.D.U. is a self-report questionnaire with 32 Likert-type items and its content development was based on a review of relevant literature, expert review and pilot testing. The scale’s construct validity is assessed by means of a preliminary exploratory factor analysis (EFA) and a subsequent confirmatory factor analysis (CFA). The results suggest a correlated four-factor structure: 1) familiarity with different types of electronic dictionaries and the conditions of their use; 2) strategies for lemmatization and acquaintance with dictionary conventions; 3) navigation skills; and 4) look-up strategies in new electronic environments. Internal consistency reliability of the four subscales is high and test-retest reliability is excellent. Also, the ability of the instrument to discriminate between experts and non-experts in electronic dictionary use is demonstrated. Results are discussed and implications are provided in the context of electronic lexicography.
