The Balanced Inventory of Desirable Responding (BIDR) is one of the most commonly used measures of socially desirable responding. It consists of two subscales, Self-Deceptive Enhancement (SDE) and Impression Management (IM), containing 20 statements each, answered on a 7-point scale. The purpose of this paper was to analyze the items on the SDE and IM for a suggested short form version of the scale. Three studies were conducted using the Icelandic version of the BIDR. The first study (N = 579) focused on analyzing the items using Confirmatory Factor Analysis (CFA) and Item Response Theory (IRT), the second study (N = 471) examined the effects of faking instructions on an item level and in the third study (N = 20) Cognitive Interviews (CI) with probing were used in order to identify problematic items. Based on results from CFA, IRT, the effects of instructional variations and CI, a short form version of the BIDR-6 was introduced, containing 12 SDE items and 12 IM items. The results suggest that the psychometric properties of measurements obtained with the short form version were adequate.
