fective treatment for patients suffering from bulimic disorders,
however this hypothesis needs to be tested in an experimen-
tal way.

MINDFULNESS-BASED PREVENTION OF DISORDERED
EATING: PRELIMINARY FINDINGS FROM A RAN-
DOMISED CONTROLLED TRIAL
Melissa J Atkinson, Tracey D Wade
Flinders University, Adelaide, Australia
Introduction
. This study examines the utility of a mindful-
ness-based eating disorder prevention program in a sample
of high school students.
Methods
. Adolescent girls (
N
= 127,
M
age
= 15.99,
SD
= .57) participated in a 3-week mindfulness
program, completing pre- and post-intervention measures of
eating disorder behaviors (EDE-Q) and related risk factors.
Acceptability was rated at post-intervention using 5-point
Likert scales ranging from
not at all
to
very much
.
Results
. No
significant pre-post changes were found for eating disorder
behaviors, weight and shape concern, emotion regulation,
or negative affect. Findings showed small but significant
reductions in escape-avoidant coping (
d
= .27), dietary
restraint (
d
= .30), thin-ideal internalisation (
d
= .25), and
thin-ideal pressure (
d
= .30). Significant increases were found
for mindfulness (
d
= .33), and self-compassion (
d
= .27).
Students’ ratings of enjoyment (
M
= 2.18,
SD
= .95), under-
standing (
M
= 3.42,
SD
= 1.01), ease of use (
M
= 3.09,
SD
=
1.00), effectiveness (
M
= 2.17,
SD
= 1.05), and likelihood of
continued use (
M
= 1.74,
SD
= .99) indicates low to moderate
program acceptability.
Conclusions
. Mindfulness approaches
are showing promise in the treatment of eating disorders;
however, have yet to be investigated in a prevention context.
This research represents a novel approach to eating disorder
prevention, with early findings indicating moderate support for
reducing the risk of disordered eating in adolescent girls.

Effects of baclofen or naltrexone, alone or in combina-
tion, on binge eating in rats

Introduction:
Binge eating has similarities to drug abuse,
and pharmaceutical treatments used to treat drug addiction
can also affect binge eating. Specifically, the GABA agonist
baclofen (BAC) can reduce intake of some drugs of abuse
as well as fat, and naltrexone (NAL), an opioid antagonist,
can suppress alcohol and food intake. The present study
tested the effect of NAL-BAC combinations on binge intake
of fat- and sugar-rich diets.
Methods:
Male Sprague-Daw-
ley rats (n=10/group) were maintained on binge access to
standard chow and a 10% sugar solution, 10% sugar-35%
fat emulsion, or 35% fat emulsion, for 21 days. The rats were
then given i.p. injections of NAL (0.1 or 1.0 mg/kg), BAC (1.0
or 1.8 mg/kg) and NAL-BAC (0.1 mg/kg NAL and 1.0 mg/
kg BAC, or 1.0 mg/kg NAL and 1.8 mg/kg BAC).
Results:
NAL-BAC (1.0 and 1.8 mg/kg, respectively) suppressed binge
eating. Cohen’s
d
revealed that NAL-BAC was more effec-
tive in decreasing intake than either drug alone, both 1 and
12 h after injection. Similarly, BAC (1.8 mg/kg) suppressed
intake in the fat and sugar-fat groups up to 12-h post injec-
tion, but did not affect intake in the sugar group. NAL alone
did not suppress intake, and none of the drugs decreased
chow intake.
Conclusions:
These results suggest that the
combination of BAC and NAL is superior to either drug alone
in suppressing binge intake of palatable foods rich in fat and/
or sugar, and this combination might be a useful therapeutic
tool for patients who binge eat.

EARLY INTERVENTION IN EATING DISORDERS: THE
EUROPEAN INITIATIVE PROYOUTH

Introduction: Many individuals with ED seek professional help
late or not at all. It is assumed that Internet-based programs
may facilitate access to regular care by providing low-thresh-
old access to information and support. The European project
ProYouth (www.proyouth.eu) evaluates an online program
for prevention and early intervention in terms of its reach and
impact on young people’s help seeking behavior and service
utilization. Methods: Prior to the implementation of the pro-
gram in several European countries, 399 German female high
school students (aged 15-18) were surveyed. Participants’
help seeking intentions, attitudes towards the online pro-
gram, risk for ED and ED-related symptoms were assessed.
Results: 77% of participants reported that they would not
utilize face-to-face professional help in case of an ED, mainly
because of concerns to be “branded as sick or mentally disor-
dered” (67%) and shame (48%). Attitudes towards the online
program were overall positive and the majority of participants
said that they would use it if needed. No differences were
found between participants who reported an elevated risk
or ED symptoms versus those who did not. Conclusion: The
findings confirm shame and fear of stigmatization as barriers
to help seeking. They support the assumption that the online
program may help to reduce such barriers. Ongoing research
will show to which extent the program impacts the actual utili-
zation of online and face-to-face professional support.

Introduction:
Compared to psychotherapy trials for buli-
mia nervosa (BN) and binge eating disorder (BED), higher
dropout rates and lower adherence would be expected for
manualized self-help interventions. However, more system-
atic investigations are lacking. Accordingly, the objectives
of this meta-analysis are to assess different measures of
adherence and dropout in self-help interventions and to
examine the effect of moderators of the intervention (e.g.
guidance) on these.
Method:
44 trials on manualized self-
help interventions for BN and BED including 33 trials using
self-help books, 6 trials using CD-ROM-versions, and 5 trials
using Internet-based delivery were identified. Drop-out-rates
and different measures of adherence as well as intervention
effects for eating disorder specific outcomes (abstinence,
binge eating, purging, related attitudes) were determined
and analyzed using meta-analytic techniques.
Preliminary
results and conclusion:
Large variations (6-80%) in drop-
out-rates and rates of participants completing the intervention
(by author definition) were observed. Guidance did not seem
to moderate adherence and dropout. Online-interventions
showed lower adherence rates compared to other forms of
delivery. Mean intervention effects were larger for studies with
higher adherence. Implications of these results as well as
different assessment methods of adherence are discussed.
Further subgroup and moderator analyses will be conducted.

Introduction
For the severe obese children behavioural
treatment results in only small changes in relative weight and
frequent relapse. The current study investigated the possible
role of an Executive Functioning (EF) training with game-el-
ements on weight loss maintenance in obese children, over
and above the care as usual.
Methods
Forty four children
(aged 8-14 years) in the final months of a one year inpa-
tient treatment program in a medical paediatric centre were
randomized to either the EF training condition or to a care-as-
usual control group. The EF training consisted of a 25-ses-
