Psychometric evaluation and short form development of the Balanced Inventory of Desirable Responding (BIDR-6)

Summary/Abstract: The goals of this research were to evaluate the Bosnian-Croatian-Serbian (BCS) translation of the BIDR-6 scale, develop its short form, and to present its initial convergent/discriminative validation. The sample included 827 participants. MIRT CFA analysis revealed that fourfactor model (containing 32/40 items) fits the data best, with Self-Deceptive Enhancement (SDE) and Impression Management (IM) both splitting into the denial (SD-D and IM-D) and enhancement (SD-E and IM-E) factors. Fit and item properties were generally mediocre. SD-D and IM-E subscales were the strongest sources of misfit, thus SD-E and IM-D subscales were retained in the short form, which had good fit and replicated almost all main patterns of associations with other variables of interest (e.g., HEXACO personality traits) typically reported for the full SDE and IM scales in other research. Thus, 17-item BIDR-6 short form, containing only SD-E and IM-D subscales, is recommended for use in the BCS speaking area.
