Objective: The constructs of interrogative suggestibility (IS) and compliance are particularly relevant within forensic settings where they may compromise the reliability of testimony. Both constructs may be influenced by individual difference factors such as personality, anxiety, self-esteem, memory and intelligence. This was one of very few studies to investigate the relationship between IS and personality disorders (PDs) and PD traits. In a replication and expansion ofa study by Gudjonsson and Main (2008), the relationship between compliance and PDIPD traits was also explored. Design: This study adopted a cross-sectional, correlational design. Participants completed measures ofP D, IS, compliance, estimated IQ, anxiety and self-esteem during a single testing session. Participants: Eighty-seven participants with a history of substance misuse and/or homelessness were recruited from charities/voluntary sector organisations across the south of England. - Results: Contrary to the hypotheses, no positive correlations were found between IS and any PDs investigated. However, negative relationships were observed between IS and several PDs/PD traits and clinical syndromes; this may be due to elements of paranoia, suspicion and distrust of others, which are antithetical to IS. Regarding compliance, this study largely replicated the results of Gudjonsson and Main (2008), finding positive correlations between compliance and various PDs/PD traits, and Cluster C PDs in particular. The possibility that the key link with compliance and these PDs was through anxiety and low self-esteem was explored using mediation analysis. Although both constructs were partial mediators, a significant proportion of the variance remains unexplained. Conclusions/lmplications: It would appear that the key components of compliance are more related to PDslPD traits than those of IS. Important implications have been outlined, including with regards to the potential vulnerability of individuals with certain personality styles/clinical syndromes and the corroboration of evidence regarding high compliance scores. Ideas for further research have been proposed.
