The aim of this study was test the efficacy of a guided self
help manual in the treatment of Bulimia Nervosa, Binge
Eating Disorder and Atypical Bulimia Nervosa. A self help
manual was developed and used as part of a guided self
help program. Participants were assessed at the beginning
and the end of the treatment and reassessed at follow up at
6 moths using Eating Disorder Examination Questionnaire
(EDE-Q), Outcome-Questionnaire – 45 (OQ-45) and Beck
Depression Inventory (BDI). In order to monitor the change
in treatament we used Short evaluation for Eating Disor-
ders (SEED) and Outcome Questionnaire (OQ-10) in every
session. Forty one patients participated in this study with
Bulimia Nervosa diagnosis or Binge Eating Disorder. Results
showed a significant reduction in EDE scores for all scales
and for OQ-45 and BDI. Reliable and Clinically significant
change occurred for the majority of participants all eating
dimensions. Participants considered to have “improved” or
“much improved” with treatment. Self help treatment showed
to be efficient in improving the clinical state of the participants
in regard to their eating behaviour and psychological distress.
Significant change occours at 3rd session for at least 50% of
the participants. Results are discussed in terms of statistical
and clinical significance.

HOW IS REWARD SENSITIVITY RELATED TO BODY
WEIGHT IN CHILDREN?

Introduction
: Previous research assumes that there are two
seemingly opposing hypotheses for the relation between re-
ward sensitivity (RS) and bodyweight: hyper-responsiveness
model and reward deficiency syndrome (RDS), leading to the
proposition of a feed forward process of weight gain. High RS
may contribute to overeating and weight-gain among normal
weight individuals. Over time the excessive food-intake may
evolve in a down-regulation of dopamine (RDS), resulting in
overeating as a form of self-medication and the progression
to obesity. This process was evidenced in adults showing a
curvi-linear relationship between self-reported RS and BMI.
The aim of the current study was to investigate the associa-
tion between self-reported RS and BMI in children.
Methods
:
438 children (10-15 years; 52.5% female) completed the BIS/
BAS self-report scale and reported on their weight and height.
A quadratic regression model of BAS Drive on BMI was fitted.
Gender and age effects were controlled for.
Results
: The
results confirm the non-linear relationship between RS and
body weight and support the suggestion of the same feed for-
ward process in children.
Conclusion
: These findings imply
that it is crucial to reduce the intake of high palatable foods in
high RS children to prevent the decrease in RS and reduce
the risk for future weight gain.

THERAPISTS’ LEVEL AND FIELD OF EDUCATION ARE
ASSOCIATED WITH CHOICE OF PSYCHOTHERAPY FOR
EATING DISORDERS

Purpose. This study aimed to ascertain whether community
therapists’ educational field and highest degree influenced
their selection of psychotherapeutic approaches for eating
disorders (EDs). Methods. We attempted to identify and
screen all psychotherapy providers in the 15 largest popula-
tion centers in Alberta, then interviewed therapists who had
treated EDs about their training and their primary psychother-
apeutic approach for ED clients. Results. Of 573 therapists
screened, 130 had treated EDs, and 118 (90.8%) completed
a phone interview. Level of highest degree ranged from
doctorate (30.5%) to master’s degree (54.2%) to bachelor’s
degree (13.6%) or less (1.7%). The frequency of use of psy-
chotherapeutic approaches varied by education level, X
2
(26,
118) = 43.61,
p
<.05. For example, although most used eclec-
tic approaches, cognitive-behavior therapy (CBT) was used
more often by master’s level therapists, whereas bachelor’s
level therapists used alternative therapies more often. Thera-
pists had diverse fields of training. Psychotherapy choice also
varied by training field, X
2
(78, 118) = 105.69,
p
<.05. Notably,
CBT was used less often by social workers, physicians, and
nurses than by psychologists. Conclusions. Community thera-
pists’ field and level of education affects the psychotherapies
they choose to use for ED clients. Efforts to disseminate
evidence-based therapies should consider the diversity of ED
therapists’ training backgrounds and perspectives.

Introduction: The Internet-based prevention program Student
Bodies+ (SB+) has proven effective in reducing symptoms
and attitudes of disordered eating in women with subthresh-
old eating disorders (ED; Jacobi et al., 2012). However, dif-
ferential outcome effects have been observed and the exact
mechanisms of change remain unclear. Therefore, the aim
of the current study is to examine moderator and mediator
effects of the intervention SB+. Methods: 126 women with
subthreshold ED participating in a randomized controlled trial
were assessed at four time points. Moderator and mediator
analyses were carried out using hierarchical linear models.
Main outcomes were binge and purge rate, restrictive eating,
and EDE-Q total score. Results: Moderators of intervention
effect on binge rate were age, depression (BDI), BMI, and
baseline binge and purge rates. Moderators of intervention
effect on purge rate were BDI, BMI, EDI-2 Drive for Thinness,
and motivation for change of eating behavior. Confidence in
improving one`s eating behavior was a moderator of interven-
tion effect on restrictive eating. No significant mediators or
moderators of intervention effect on EDE-Q total score were
found. However, the intervention effect on binge and purge
rates was mediated by an increase in relevant knowledge.
Conclusion: The results inform about the selection of target
groups and the conceptualization of tailored contents of future
indicated preventive interventions for ED.

Purpose: Asses in a long-term follow-up study, if new tech-
nology assisted guided self-help is efficient for adolescents in
the treatment of bulimia nervosa (BN). Methods: Twenty nine
female adolescents and 97 female adults have been treated
with Internet based guided self-help or bibliotherapy, both
guided by regular e-mail contact. In the adolescent group,
69% completed the intervention vs. 59.8% in the adult group.
Results: Follow-up evaluations after treatment showed that
in the adolescent group 44.4% are symptom free (defined by
lack of binge eating episodes and compensatory behaviours)
or in remission (do not fullfill DSM-IV criteria for BN) vs.
38.7% in the adult group. In the long term follow-up after
1.5 years, remission rates could be extended to 55% in the
adolescent group vs. 62.5% in the adult group. Mean monthly
bingeing behaviour decreased from 46.31 at the beginning
of the intervention to 31 at the end of treatment and 17.88
at 1.5 years follow-up in the adolescent group and from
25.32 to 10.95 at the end of treatment and 11.27 at 1.5 years
follow-up in the adult group. Mean monthly vomiting episodes
decreased from 73.44 to 30.25 at the end of treatment and
18.19 at 1.5 years follow-up in the adolescent group and
from 37.67 to 15.4 at the end of treatment and 11.33 at 1.5
years follow-up in the adult group. Time effects (p<.000) but
no time by group effects could be found neither for binge
eating (p=.287) nor for vomiting (p=.186). Conclusion: New
