Recently, researchers have started searching for combinations of verbal cues to deceit and verbal cues to truth. The proportion of complications (complications divided by complications plus common knowledge details plus self-handicapping strategies) is an example of such a combination, as it includes one verbal cue of truth (complications) and two verbal cues of deceit (common knowledge details and self-handicapping strategies). This study examines whether or not complications, common knowledge details, self-handicapping strategies and the proportion of complications can differentiate truth-tellers from liars in interpreter-absent and interpreter-present interviews. Both interpreter-absent and interpreter-present interviews take place frequently, and it is important to know whether or not any given lie detection tool works in both interview settings. For this purpose, three data sets were obtained and the data were aggregated. All four variables were found to differentiate truth-tellers from liars to a similar extent in both interpreter-absent and interpreter-present interviews.
