The roles of interviewing conditions and individual differences in memory and suggestibility: An online interview study

Abstract

In existing studies of investigative interviewing, the effects of interviewing contexts have often been measured with little consideration of the reciprocal interviewee's stable characteristics. To clarify the factors and conditions under which adults are likely to retain accurate information and be resistant (or vulnerable) to suggestions during interviews, this study systematically explored the relative contributions of interviewing conditions (i.e., interviewer behaviour and exposure to post-event misinformation) and individual differences (i.e., HEXACO personality traits, perceived parenting styles, social trait and state anxiety). A total of 159 Malaysian adults (M = 24.70; SD = 5.48) were assessed virtually using the Gudjonsson Suggestibility Scale 1. Hierarchical regression analyses revealed that higher recall accuracy was linked with supportive interviewer behaviour and non-exposure to misinformation. Notably, individual's personality traits and developmental environment emerged as significant predictors of recall and suggestibility. The implications of remote interviewing in investigations are also discussed.
