faction and bulimic symptoms were semi-randomly assigned
to one of the two mirror exposure conditions: a) pure mirror
exposure (N =12) and b) guided mirror exposure (N =11). All
participants received six sessions of 50-minutes exposure
each and distributed twice a week. Subjective psychological
changes were measured during treatment through (a) positive
thoughts/ beliefs and (b) feelings of satisfaction with one´s
body.
Results:
The results showed a progressive and sig-
nificant increase in the frequency of positives thoughts and
beliefs as well as in satisfaction with one´s body between ses-
sions in both groups. However, these changes were notably
higher in the pure mirror exposure group.
Conclusions:
The
findings reveal that pure mirror exposure is a useful strategy
to increase body satisfaction and positive thoughts and beliefs
associated with body image along the therapy in bulimia
nervosa.
Keywords
:
positive body thinking, body satisfaction,
mirror exposure.

Day Hospital (DH) treatment is associated with weight resto-
ration and symptom control for many individuals with anorexia
nervosa (AN), but there are few reports on the durability of im-
provements over time. The aim of this study was to document
the rate of relapse and identify predictors. Participants were
49 patients with AN who were weight restored (BMI > 19.5),
had at most one episode of bingeing or purging in the last 4
weeks of DH treatment and attended follow-up assessments.
Relapse was defined as a BMI of 18.5 or less for 3 months
or bingeing or purging at least twice per week for 3 months.
Potential predictors included clinical features and scores on
psychological tests. Data were analyzed with survival analysis
and Cox regression. The relapse rate was 54% at 12 months.
Predictors of relapse included binge-purge subtype (p<.02)
and pretreatment self-reported readiness to recover (p<.05).
For AN restricting subtype (AN-R) the relapse rate was 42%
at 12 months while for the binge-purge subtype (AN-BP) it
was 70%. Within diagnostic subtypes, pretreatment readiness
to recover was a strong predictor of relapse status for AN-R
(p<.001) and was not significant for AN-BP. The very high
relapse rate for AN-BP suggests that DH may not be the treat-
ment of choice for this subgroup, while the robust association
between relapse and self-reported readiness for recovery in
AN-R suggests that these patients may be well qualified to tell
us how they will be doing over the next year.

ATTENTIONAL BIAS, EATING STYLES AND ATTACHMENT
IN FEMALE COLLEGE STUDENTS
Machteld A. Ouwens
Tilburg University, Tilburg, Netherlands
Introduction: An attention bias for food and body words was
found in 45 eating disordered patients and remarkably this
bias diminished after priming with the name of an attachment
person (Admoni, 2006, in Mikulincer & Shaver, 2007). Aim of
the present study is to replicate this finding, using the eating
styles to measure eating disturbances in female college stu-
dents. Method: A total of 98 women participated in a STROOP
task (with food, body and neutral words) in which they were
primed with their attachment person, a close person or an
acquaintance. Food intake (crisps and M&M’s) was measured
while they were watching the sad movie the Champ. And they
also filled out the DEBQ (eating styles: emotional, external or
restrained eating) and the ECR (attachment styles: anxious
and avoidant). Results: None of the three eating styles was
related to longer reaction times on the food and body words.
Priming did not affect the reaction times of the emotional,
external or restrained eaters. Food intake was only significant-
ly predicted by external eating (Beta = .274, p <0.012), not by
the other eating styles, the attachment styles, primes or by
reaction times. Conclusion: The results of the previous study
were not replicated in a sample of female college students.

Introduction. Attrition rates in Bulimia nervosa (BN) during
routine clinical practice with CBT are high. Non-adherence
has been related to depression, but CBT as other brief
interventions focus from the beginning on reducing extreme
dietary restraint to stop binge eating and do not address mood
disturbances. Therefore, by using an expanded subtyping
version of Stice’s model of binge eating based on 4 types
according to scores on Drive for Thinness (DT) and depres-
sion (Peñas Lledó et al., 2009; Beh Res and Ther), it was
hypothesized that the highest and lowest rate of dropout will
be presented by the groups with high depression-low DT and
high DT- low depression, respectively. Methods. A total of
154 adult females meeting DSM-IV-TR criteria for purging BN
(BN-P) gave consent to participate. Treatment consisted of 22
(8-10 outpatients) 90-minute sessions over 20 weeks (twice
weekly for the first 2 weeks). This comprised 6 initial sessions
of brief psychoeducation followed by16 of CBT. Patients
were assessed with the Eating Disorders Inventory-2 and the
Symptom Checklist-90-Revised. Results. Overall attrition rate
was 33%. Attrition rates differed between subtypes, being
higher in the “depressive” subtype (60.5%) than in the rest,
and lower in the “pure DT” (18.5%). Conclusions. This new
model showed predictive validity as an instrument to identify
BN-P at risk of dropout from CBT in an unselected population.

Background:
There is growing evidence that Cognitive Reme-
diation Therapy (CRT) in individual and group formats, has
a useful role in the treatment of adults with anorexia nervosa
(AN). There is also emerging evidence that adolescents with
AN may have some of the neuropsychological inefficiencies
found in adults but the evaluation of CRT with adolescents
with AN is very limited.
Purpose of study:
To evaluate the
outcomes of a CRT group for adolescents with AN, specifically
to assess changes in cognitive flexibility and the adolescents’
experience of taking part in the group.
Methods:
Seven CRT
groups were carried out with a total of 30 adolescents with
AN. Adolescents’ cognitive flexibility and motivation was
assessed before and after the group and they completed
qualitative questionnaires after the group to determine their
perceptions of the group.
Results:
There was a small effect
size in self-reported cognitive flexibility post group. Adoles-
cents found the group interesting and useful, however, some
wanted more support with translating the group experience
by applying it to real life situations.
Conclusions:
CRT has the
potential to be used with adolescents with AN. More research
is needed to determine the specific effects of CRT using neu-
ropsychological assessments as well as self report measures
and whether there are particular sub-groups of young people
with AN who are most likely to benefit.
