Does trauma memory play a role in the experience of reporting sexual assault during police interviews? An exploratory study
Abstract
A recent study indicated that 94.4% of reported sexual assault cases in the UK do not result in successful legal prosecution, also known as the rate of attrition (Kelly, Lovett, & Regan, 2005). Scant research has examined the role of trauma-related psychological processes in attrition. Victims of sexual assault (N =22) completed questions about peri-traumatic dissociation, trauma memory fragmentation, account incoherence during police interview, and likelihood of proceeding with legal cases. Higher levels of dissociation during sexual assault were associated with participants reporting more fragmented trauma memories. Memory fragmentation was associated with participants indicating that they provided more incoherent accounts of trauma during police interview. Importantly, people who viewed themselves as providing more incoherent accounts predicted that they would be less likely to proceed with their legal cases. The findings suggest trauma impacts on memory, and these trauma-related disruptions to memory may paradoxically contribute to attrition.

Hardy et al. found that peritraumatic dissociation on the PDEQ was moderately to strongly positively related to two single-item meta-memory fragmentation measures.
“Self reports of peritraumatic dissociation, assessed using the Peritraumatic Dissociative Experiences Questionnaire (PDEQ; Marmar et al., 1997), were moderately to highly positively associated with two single items of meta-memory fragmentation, assessing “fragmented pieces” and “account incoherence”.”

Across Criterion A trauma samples, higher peritraumatic dissociation consistently accompanied higher self-rated fragmentation.
“Taken together results of Halligan et al. (2003), Murray et al. (2002), and Hardy et al. (2009) generally suggest that, in Criterion A trauma-exposed samples, individuals with higher peritraumatic dissociation consistently show higher meta-memory ratings of fragmentation.”

“However, Bögner, Herhily, and Brewin (2007) found that, in a sample of 27 asylum seekers, PTSD symptoms (which arise due to disruptions in memory processing) had a detrimental impact on the reporting of events, as assessed by difficulty in disclosing trauma during Home Office interviews.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
