disordered eating attitudes (body shame) and behaviors (dieting). Female
college students (
N
=99) completed an online survey and responses were
analyzed using bootstrapping analyses for estimating indirect effects in
models with multiple mediators. The total indirect effect of relationship
contingent self-worth on body shame through the set of mediators was
significant (
p
<.001); specific indirect effects showed that perfectionistic
self-presentation was a unique and significant mediator (
p
<.01), but
body surveillance was not (
p
=.072) – however, a contrast indicated that
neither indirect effect was significantly stronger. For the relation between
relationship contingent self-worth and dieting, the indirect effect through
the set of mediators was significant (
p
<.01), but neither specific indirect
effect was significant. Findings suggest that, as a set, perfectionistic self-
presentation and body surveillance partially mediate the relation between
relationship contingent self-worth and both body shame and dieting.
Interventions that disrupt these pathways may prove fruitful in decreasing
likelihood of disordered eating attitudes and behaviors.

Introduction
.
Eating disorders (ED) and ADHD are both significant
public health issues. Although there is evidence to suggest co-morbidity
of these issues, evidence is limited to female clinical populations. The
two-fold purpose of this study was to: a) determine the co-occurrence
of diagnosed (DX) ADHD and ED in a nationally representative sample;
and, b) explore gender differences in the comorbidity.
Methods
.
A
secondary data analysis was conducted using the National Longitudinal
Study of Adolescent Health (n=14,275). Logistic regressions were used to
determine the association between ADHD with ED. Stratification by gender
and proper sample weights were applied to analyses.
Results
.
Females
with ADHD were 3x more likely to have ever been DX with ED (p<.001).
Males with ADHD were 4x more likely to have been DX with ED (p=.057).
Moreover, females with ADHD were 2x more likely to report binging and/
or purging behavior (p<.05); no relationship was found between ADHD
and restrictive behavior. Males with ADHD were 3x more likely to report
binging and/or purging behavior (p<.001) and 1.5x more likely to report
restrictive behavior (p<.05).
Conclusions
.
Implications from the current
study include: a) monitoring of adolescents of both genders with ADHD for
binging and/or purging behavior; b) monitoring of ADHD medication side
effects for the development or continuation of restrictive eating behaviors,
especially among males who may be at increased risk for restrictive
behavior.

Due to comorbid anxiety and alexithymia in anorexia nervosa (AN), this
study evaluated self-reported anxiety and brain activity. 2. We present
findings from an ongoing study with 14 weight-restored AN patients and
20
healthy controls who viewed images of fearful faces during fMRI scans.
Participants rated anxiety in response to faces. We hypothesized that
individuals with AN would show greater amygdala activity and less medial
prefrontal cortex (mPFC) and anterior cingulate cortex (ACC) activity in
response to faces compared to controls. We also predicted that there
would be a discrepancy between self-reported anxiety and brain activity
in the AN group, in line with alexithymia reports. 3. Individuals with AN
reported higher anxiety in response to the faces than controls. Amygdala,
mPFC, and ACC activity were not significantly different between groups.
There was a significant positive correlation between anxiety and activation
of the amygdala and mPFC in the AN group (
r
=.589,
P
=.027;
r
=.687,
P
=.007), but not in controls. 4. Self-report findings support prior evidence
of heightened anxiety in individuals with AN. The positive correlation
between amygdala activity and anxiety ratings in AN, in the absence of
evidence of abnormal fronto-limbic activation, suggests a heightened
sensitivity to change in limbic regions, which is incongruent with reports
of alexithymia. These findings have significance in understanding the
underlying neural processes related to anxiety in AN.

Beliefs and Attitudes About Disordered Eating aAnd School-Based
Prevention: A Comprehensive Needs Assessment Targeting Parents
and Staff

The current study aimed to assess eating disorder prevention needs
at a private boarding school on the Island of Hawai’i. At baseline, a
comprehensive survey explored parents’ (
n
= 51) and faculty members’
(
n
= 15) attitudes and beliefs about disordered eating, as well as their
views about the school-based prevention of a range of problems that
may impact young women. Faculty members’ perspectives on the school
culture concerning eating and weight were assessed at baseline and
at the end of the school year as part of an evaluation of a pilot peer-led
dissonance-based eating disorder prevention program. Participants in
the current study expressed reasonable support for the school-based
prevention of eating- and weight-related concerns, although prevention
efforts targeting obesity were rated as more important than those aimed
at the prevention of eating disorders. Additionally, some degree of anti-fat
attitudes, body dissatisfaction, and restrained eating were found in the
current sample, with rates similar to, or higher than, those found in other
community samples. Finally, although the pre-post sample was small (
n
= 7), faculty participants perceived the school culture around eating and
weight to be significantly worse at the end of the school year, despite
the implementation of a prevention program. Study findings suggest that
providing targeted education to parents and faculty may be one way to
enhance the overall impact of school-based eating disorder prevention
programs.

Introduction:
Resumption of menses is an important indicator of recovery
in anorexia nervosa (AN). Particularly patients with early-onset AN are
at great risk to suffer from physical and neuropsychiatric long-term
consequences resulting from persistent endocrine dysregulation. However,
the clinical parameters that predict recovery of ovarian function during
weight gain in AN remain poorly understood. The aim of this study was
to investigate the impact of several clinical parameters on resumption of
menses in first-onset adolescent AN.
Methods:
172
female adolescent
patients with first-onset AN were recruited within a randomized, multi-
center clinical trial in Germany. Menstrual status and clinical variables
(
premorbid BMI, age at onset, primary or secondary amenorrhea, duration
of illness, current BMI) were assessed at admission to hospital treatment
and at a 12-months follow-up.
Results:
46%
had spontaneously started
to menstruate during the follow-up period. BMI at the 12-months follow-up
was strongly correlated to resumption of menses. Primary amenorrhea,
premorbid BMI, BMI at discharge and duration of hospital treatment
predicted menstrual status at follow-up.
Conclusions:
A target weight near to premorbid weight is favorable
in terms of resumption of menses within one year. Patients with
premenarchal onset of the eating disorder are at particular risk for
protracted amenorrhea despite weight rehabilitation.

Introduction:
Approximately 20 to 50% of patients begin to regain their
weight within the first 1 ½ to 2 years following bariatric surgery. Eating
self-efficacy in non-bariatric samples has been shown to predict the
maintenance of behavioural change, including weight loss and abstinence
from binge eating. The current study examines the impact of cognitive
behavioural therapy (CBT) on eating self-efficacy using a measure
recently developed by our team (Ontario Bariatric Eating Self-Efficacy
[
OBESE] Scale - 2 subscales: ability to resist overeating and ability to
follow bariatric surgery dietary guidelines).
Methods:
Bariatric surgery
patients participate in a 6-session manualized telephone-based CBT
intervention and complete the OBESE scale immediately pre- and post-
CBT.
Results:
Data collection is currently underway. To date, 18 patients
have completed CBT and 22 additional patients have been recruited and
are expected to complete CBT within the next 4 months. Descriptive data
on eating self-efficacy in bariatric surgery patients will be reported, as well
as changes in eating self-efficacy following CBT.
Conclusion:
This study
has the potential to identify areas of low eating self-efficacy in bariatric
surgery patients and demonstrate the ability of a psychosocial intervention
to improve eating self-efficacy—a finding which could have important
implications for the maintenance of behavioural change and weight loss
following bariatric surgery.
