Conclusions:
These novel findings
suggest that even lean individuals may internalize weight bias. Importantly,
the internalization of weight bias among lean individuals is predictive of
clinically significant eating pathology.

Introduction
:
Anorexia Nervosa (AN) is characterized by preoccupying
thoughts and ritualistic behaviors related to eating, exercise, and body
shape/weight. The Yale-Brown-Cornell Eating Disorder Scale (YBC-EDS)
was developed to assess the degree of impairment associated with these
eating disorder specific obsessive-compulsive tendencies that are not
targeted by other OCD symptom measures. The YBC-EDS consists of
a Severity Scale and a Symptom Checklist, which includes categories
of preoccupations and rituals. While the Severity Scale has been used
to examine the impact of preoccupations and rituals on functioning, the
Symptom Checklist has not received much empirical attention. The purpose
of the current study is to better understand the specific symptoms identified
by the YBC-EDS among women with AN.
Method
:
YBC-EDS data were
collected from women with AN (N = 30) presenting for inpatient treatment
on a specialized clinical research unit.
Results
:
Participant characteristics as well as data from the YBC-EDS
Symptom Checklist will be presented. Specifically, the total number of
preoccupations and rituals, frequencies of typically endorsed items, and
correlations between symptom categories and overall symptom severity
will be reviewed.
Conclusions
:
Clinical applications of these findings in
terms of informing assessment and treatment of women with AN will be
addressed. Additionally, implications regarding the utility of using the YBC-
EDS in future research will be discussed.

Purpose
:
Thin ideal internalization is believed to contribute to the
development and maintenance of AN. Few studies have experimentally
examined preferences for ideals of varying degrees of thinness and how
these preferences relate to ED symptoms. This study tested whether
AN women implicitly associate emaciation with beauty.
Methods
:
30
participants with AN symptoms and 29 controls were primed with
emaciation or thinness and then completed a lexical decision task (LDT).
The LDT consisted of 48 nonwords and 48 words (12 beauty words, 12
ugly words, 12 neutral words, and 12 positive words).
Results
:
A significant
Group X Prime X Word Type interaction emerged for response time
latencies (
p
=.05). As expected, follow-up tests revealed that AN women
primed with emaciation responded faster to beauty words than controls
(
p
=.05); unexpectedly, AN women primed with emaciation also responded
faster to ugly words than controls (
p
=.01). Further, AN women primed with
emaciation responded faster to beauty (
p
=.09) and ugly (
p
<.01) words
than AN women primed with thinness. Among participants primed with
emaciation, EDEQ-4 subscales were significantly associated with reaction
times to beauty and ugly words.
Conclusions:
Compared to controls,
AN women were more likely to implicitly associate emaciation with both
beauty and ugliness. Implications for using implicit associations to monitor
treatment progress and to aid diagnostic decision making and treatment
planning are discussed.

Disordered Eating pathology represents a complex of thoughts and
behaviors, encompassing the entire spectrum from body image related
problems up to the development of full-blown Eating Disorders. The risk
factors are multi-factorial, including personality factors, familial factors, and
socio-cultural factors. A sense of empowerment is found to be a promising
protective factor. Thus, the aim of this study is to examine the relationship
between disordered eating pathology, exposure to media messages,
and sense of empowerment, among female adolescents in Israel. It also
aims to determine the effect of parenting style on the daughters’ sense
of empowerment. The research was based on the Objectification and
Social Comparison Theories.
Method
:
Participants were 248 females,
aged 12-19 who completed self-report questionnaires: demographic,
exposure to harmful media massages, Eating Attitudes Test; Eating
Disorder Inventory 2; Body Shape Questionnaire and the Empowerment
Scale.
Results
:
Disordered eating and poor body image were found to
be significant correlated with harmful media massages, emphasizing the
use of “Facebook” and music videos. Significant positive correlations were
also found between disordered eating and sense of empowerment, and
between authoritative parenting style and sense of empowerment among
the daughters.
Conclusion:
Findings highlight the need for parents’
involvement in prevention interventions in terms of training, guidance and
setting clear boundaries.

Introduction
.
The performance of individuals with “restricter” or “binger-
purger” eating-disorder (ED) variants tends to differ on tasks measuring
executive functions, with restricters (on average) showing superior planning
and problem solving.
Methods
.
We engaged 48 women—19 with EDs
in a restricting type spectrum (i.e., “Restricters”), and 29 with bulimia-
spectrum disorders (i.e., “Bingers/Purgers”)—in a functional magnetic
resonance imaging (fMRI) paradigm that examined brain activations
during the performance of a modified Nback task (thought to tap working
memory and planning functions).
Results
. “
Bingers-purgers” were poorer
than “restricters” at high-demand levels of the Nback. In parallel, during
performance of the NBack, restricters showed greater activation than did
bingers in a right posterior DLPFC region (spanning Brodman Areas 6 and
8).
Discussion
.
Our findings imply that restricters are superior to bingers
in the performance of serial mental operations in working memory, and link
such differences to interpretable differences in brain-activation—restricters
(
when compared to bingers) showing more activity in a right DLPFC that
has previously been thought to subserve the mental operations in question.
Such differences could account, in part, for characteristic behavioral
differences related to self control seen in the clinical profiles of restricter
and binger patients.

Introduction:
Whilst hyperactivity and excessive exercise are recognised
features of anorexia nervosa (AN), the extend to which patients experience
a
drive
for activity remains understudied. A drive for activity has also
been linked to anxiety levels, which are commonly very high in AN, hence
highlighting the importance of studying the influence of anxiety on drive for
activity in AN. This study investigated the relation between drive for activity
and anxiety in female AN patients. We hypothesized that firstly, a high drive
for activity would be associated with high anxiety and high eating disorder
(
ED) pathology, and secondly, that those patients with high anxiety and high
drive for activity would report the highest levels of ED pathology. Lastly,
differences between restrictive and binge-purge subtypes were explored.
Methods:
Hundred-thirty female AN patients completed the Drive For
Activity Questionnaire (DFAQ), the Spielberger Trait-State Anxiety Inventory
(
STAI) and the Eating Disorder Examination (EDE). Clinical data (BMI,
duration of illness, age of onset) were recorded.
Results:
High drive for
activity levels were positively associated to both anxiety and ED pathology.
Those patients with high anxiety and high DFAQ scores had highest EDE
scores. AN subtypes did not differ in DFA scores.
Conclusions:
Not
only the actual activity, but also experiencing a
drive to be active
seems
important for AN patients, particularly in the context of high anxiety.

Introduction
:
The fact that a 4-session group dissonance-based eating
disorder prevention program, which has been disseminated in 110 US
universities, produced greater eating disorder symptom reductions for
young women with versus without a DSM-5 eating disorder (d = .71 vs.18)
prompted us to develop a new dissonance treatment for eating disorders.
