CSA Adult Survivor Memory

ABSTRACT

Past research on adult memory for childhood sexual abuse (CSA) has provided
support for the phenomenon of forgetting and subsequent recovery of the memories,
after a period of time. This phenomenon, however, remains a source of debate and is
still not fully understood by researchers and psychological and legal practitioners.
The research has provided conflicting evidence about the factors which are thought
to lead to CSA forgetting for extensive periods of time, in addition to the processes
involved in forgetting, triggering and later remembering of the abuse memories by
adult survivors.

This study utilised a mixed method to investigate and explore the factors and
processes associated with CSA forgetting, triggering and later remembering, in a
sample of Australian adult CSA survivors (N = 77). Participants were asked to
complete a test booklet, containing the Traumatic Events Questionnaire (TEQ),
Symptom Checklist-90-Revised (SCL-90-R), Dissociative Experiences Scale II
(DES II), Impact of Events Scale – Revised (IES-R), a scale designed to measure
persistence of memory (Loftus), and a scale designed to measure emotional intensity
at the time of the abuse and now (Williams). Participants were then asked to
participate in a semi-structured interview. Seventy-one participants completed the
interview process. Five separate analyses were conducted on the data.

Methodological issues, such as the use of retrospective data and corroboration of the

abuse were outlined. All participants were asked to provide details about any
corroboration they had received that the abuse had occurred.
The participants were streamed into one of three categories of forgetting (Always
Remembered, n = 28; Partial Forgetting, n = 16; and Extensive Forgetting, n = 33).
The first analysis (Stage One Analysis One) examined the factors thought to be
associated with CSA forgetting, such as abuse parameters (TEQ), current
psychological functioning (SCL-90-R), persistence of memory (Loftus), emotional
intensity at the time of the abuse and now (Williams), the trauma response
experienced at the time of the abuse (IES-R), and current dissociation (DES II), to
determine the significant differences between the three groups.

A significant difference was found regarding the age at which the abuse commenced,
with the Extensive Forgetting group reporting an earlier age at which the abuse
commenced. Significant differences were found on the variable that related to being
abused by an aunt or uncle, and on the current experience of hostility (SCL-90-R
sub-scale), and on the current levels of anger (Williams Emotional Intensity)
experienced by the participants. Significant differences between the groups were
also found on two of the Persistence of Memory items, namely clarity of memory
and participants’ memory of the tastes related to the abuse. Finally, a significant
difference was found on the participants’ current dissociation levels, with the
Extensive Forgetting group reporting higher levels of current dissociation than the
other two groups. Statistical profiles for each of the three groups were constructed,
based on the mean scores of the SCL-90-R, IES-R and DES II, for use in the Stage
Two, Analysis Two, profile comparison.


Stage Two, Analysis One, provided a qualitative analysis relating to the experience
of always remembering the abuse. The aim of this analysis was to provide a deeper
understanding of why some participants (n = 23) did not forget about their abuse,
when other participants reported being able to forget for a period of time. The results
indicated that participants’ responses formed clusters, such as older age at abuse
onset, failed dissociative mechanisms, constant reminders, and others.

Stage Two, Analysis Two, presented and compared each participant’s profile against
the statistical profiles constructed in Stage One. The participant’s profiles included a
summary of their TEQ responses and interview responses, in addition to their Stage
One test booklet scores. The comparison was made, firstly, on a specific basis
against the mean scores obtained by each category of forgetting, and secondly, on a
broader basis, against the score range for each measure of the statistical profile. This
was done to determine if there was a “typical” member of each category of forgetting
and to investigate the within-group differences. The specific profile comparison
demonstrated that there was no “typical” member of any of the three groups, with
participants varying widely in their scores and patterns of scores. However, when
the profile comparison was broadened to include score ranges, 61% of participants,
who always remembered the abuse, 44% of participants who partially forgot the

abuse, and 47% of participants who extensively forgot their abuse, matched the
profile of a “typical” member of their relevant category of forgetting.

Stage Two, Analysis Three, provided an in-depth qualitative exploration on the
process involved in CSA forgetting, triggering and later remembering, for a selection

of participants who reported partially forgetting the abuse (n = 6), and extensively
forgetting the abuse (n = 10). Participants’ interview responses were transcribed
verbatim and analysed, using Interview Analysis. This analysis explored the
differences between participants, from the two categories of forgetting, on their
experiences of CSA forgetting, triggering and later remembering, in addition to
exploring how these participants were able to forget about the abuse; what events
triggered their abuse memories; and how the initial memories returned. Issues of
memory recovery, while in therapy or under hypnosis, were also explored.

Stage Two, Analysis Four, presented the case study of a participant, who had been
identified as an “outlier”, due to her high score on the DES II, claims of being able to
remember abuse incidents that occurred prior to the age of two years, diagnosis of
DID, and the substantiated conviction and sentencing of her abuser, based on her
recovered memories of the abuse and corroboration from her sister and mother. Her
case was examined against some of the criticisms often made by false memory
supporters.

This thesis found that some CSA survivors forgot about their abuse, either partially
or extensively. The thesis also found support for some, but not all, of the factors that
previous researchers have identified as being associated with CSA forgetting by adult
survivors, specifically the individual’s age at the time the abuse commenced and the
individual’s ability to dissociate from the abuse. The research then explored, indepth, the issues of: CSA remembering, CSA survivor profiling, and the “how” of
CSA forgetting, triggering and later remembering, by adult survivors.

Acknowledgments

I would like to take this opportunity to acknowledge the people and organisations
who supported me during the completion of this thesis. Firstly, I would like to thank
the participants of this study for their courage, honesty and ability to trust a stranger

with their childhood experiences. Without their openness, this thesis would not be.
Thank you to the organisations and private therapists who helped make the
connection between the participants and this research project, in particular the
Queensland Crime Commission, Hetty Johnson, Dr. Wendall Rosevar and the After
Care Resource Centre.

Many thanks go to QUT for awarding me a three-year scholarship to conduct the
research, and to the School of Psychology and Counselling and Professor Ross
Young for the research support, which included access to funding, personnel and
sage advice.

I wish to thank my supervisory team. Sincere thanks to Professor Gary Embelton for
providing emotional support during the period of time I spent interviewing the abuse
survivors, and for believing in the merit and structure of this thesis topic, and to Dr.
Barbara Adkins for showing me the way regarding analysis of the qualitative data
with great clarity.

My deepest gratitude to Dr. Kathryn Gow, my chief supervisor, who deserves her
own paragraph for always believing in this project and my ability to complete the
process, especially when I doubted I would see the end, and for her superb “other”
management skills. I will never forget your words of encouragement and fighting
spirit, which always materialised just when I needed them the most. Finally,
Kathryn, I would like to give thanks for your sense of humour, patience, and
empathy.

The word “thanks” seems somewhat inadequate when I think of the sacrifices my
family members have made throughout the completion of my thesis. To my

xxiii

husband, Steven, and my children, Jon, Kelly and Nathan, thanks for putting up with
an often emotionally and mentally absent wife and mother.
Finally, thanks to my friends for supporting me when I made the life-changing
decision to return to full-time study. Your words were challenging at the time, and
opened me up to a new world of possibilities.
