Effects of post-traumatic stress disorder on interrogative suggestibility in minor witnesses of sexual abuse

Evaluating autobiographical skills and their relationship with suggestibility in children: development and validation of the Children Recalling Autobiographical Memory

Introduction

Autobiographical narrative skills and resistance to suggestibility factors are central aspects in children's testimony. While the assessment of suggestibility relies on standardized questionnaire, no such an instrument exists to reliably assess autobiographical skills in children. This aspect is further important when considering that the development of such skills seems to be related to the suggestibility, that is, suggestibility would be reduced in presence of higher autobiographical skills. However, no direct test of this relationship is available in literature, also due to the lack of quantitative instruments for assessing autobiographical skills.

Methods

To fulfill both these methodological and theoretical issues, in this study a new tool was validated to measure the main autobiographical narrative skills (Where, What, When, Who, and How) in relation to both Retrospective Memory and Prospective Memory: the Children Recalling Autobiographical Memory (CRAM). We recruited a sample of 321 children aged 7-16 years.

Results and discussion

The result of the EFA analysis showed one-factor model, and revealed also good fit indexes and internal reliability. After validating this new tool, we further used it to test our main hypothesis, that is, children with higher autobiographical memory skills were less vulnerable to interrogative suggestibility as assessed by Gudjonsson Suggestibility Scale 2 (GSS2). A hierarchical linear regression model showed a reduction in suggestibility with age and level of autobiographical skills. Moreover, the level of such skills moderate the effect of age, such as only in presence of high or moderate level of autobiographical skills the age significantly reduces the level of suggestibility.

Attachment and mentalization among survivors of sexual abuse: A questionnaire survey

Knowledge of the long-term consequences of child sexual abuse (CSA) is crucial to further develop preventive strategies and treatment programs. The aim of this study is to investigate attachment and mentalizing ability in people who have experienced CSA. Attachment style, measured with the Experiences in Close Relationships-Relationship Structures Questionnaire (ECR-RS), and mentalization, measured with the Reflective Functioning Questionnaire (RFQ), were examined through a quantitative questionnaire survey in a sample of 49 individuals who had experienced CSA, and a control group of 612 with no history of CSA. The CSA group was, to a greater extent, identified with insecure attachment style. In addition, participants with insecure attachment were more likely to use hypomentalizing compared to individuals identified with a secure attachment. No significant association was found between attachment style and the relationship between the victim and the offender or the length of traumatic episodes.

The Relationship between Suggestibility, Fabrication, Distortion, and Trauma in Suspected Sexually Abused Children

Being a victim of abuse in childhood can lead to the development of trauma-related psychopathology, which could affect the testimony of the child victim. Post-traumatic stress disorder (PTSD) is a factor that can increase both the levels of suggestibility and the production of memory errors, such as confabulations, which can be identified in distortions and fabrications. No studies have analyzed the relationship between suggestibility, fabrications, distortions, and PTSD on samples of children and adolescents suspected of being sexually abused. This study aims to verify in a sample of 221 sexually abused children and adolescents the effect of PTSD, measured by Trauma Symptoms Checklist for Children, in increasing the levels of immediate and delayed suggestibility and the production of fabrications and distortions in immediate and delayed memory tasks, obtained by Gudjonsson Suggestibility Scale 2, controlling age and non-verbal intelligence. Our results show that PTSD increases the levels of immediate and delayed suggestibility, but it has no effect on memory recall in immediate recall tasks. Moreover, PTSD leads to a greater number of distorted and fabricated information inserted in delayed memory. Forensic implications of PTSD consequences on memory tasks and suggestibility levels of sexually abused children are discussed.
