sion training of inhibition and working memory. Treatment
outcomes are child performances on EF-tasks and child-
care worker ratings on EF symptoms as well as weight loss
maintenance after leaving the clinic.
Results
The children in
the training condition showed significantly more improvement
than the children in the care as usual group on EF-tasks and
on the childcare worker reports, and were more capable to
maintain their weight loss until 8 weeks post-training.
Conclu-
sions
This study shows promising evidence for the efficacy
of an EF training as weight stabilization intervention in obese
children.

Introduction:
The aim of this study was to examine the effec-
tiveness of enhanced cognitive behaviour therapy (CBT-E) for
adolescents with the full range of eating disorders. There is
robust evidence of the effectiveness of CBT-E as a treatment
for adults with eating disorders. CBT-E has been adapted for
use with adolescents and there is emerging evidence for its
effectiveness in this population, although the only outcome
data available in this age group come from one study (N=51).
The current study adds to the evidence base for the effective-
ness of CBT-E in adolescents with all forms of eating disorder.
Methods:
The study was a case series involving 40 patients,
aged 16-18 years, referred to a public outpatient clinic in
Perth, Western Australia. Eighteen of these patients had
a BMI <17.5. Patients attended, on average, 28 individual
CBT-E sessions, plus up to 4 family sessions, with a clinical
psychologist.
Results:
Of those who accepted treatment
(n=38), 23 (61%) completed the full course. By the end of
treatment, good outcome was achieved by 57% of treatment
completers and 34% of the total sample. Compared to those >
18 years referred to this same service, the adolescents were
more likely to complete treatment and as likely to achieve
a good outcome. The results also compare favourably to
those reported in the only previous case series of CBT-E with
adolescents.
Conclusion:
This study provides encouraging
evidence to support the use of CBT-E for adolescent patients.

Interpersonal difficulties are thought to play a central role in
both the development and maintenance of anorexia nervosa
(AN). Aims: The primary aims of this study were to examine
the nature of interpersonal problems in AN and to determine
whether certain interpersonal problems would be related to
AN psychopathology and treatment outcome. Methods: The
participants were 218 patients with AN who were admitted to
a specialized inpatient/day treatment program. The Inven-
tory of Interpersonal Problems (Horowitz et al., 2000) and
the Eating Disorder Examination Questionnaire (Fairburn &
Beglin, 1994) were administered at pre- and post-treatment.
Results: Overall, AN patients reported a pattern of difficulties
with submissiveness, nonassertiveness and social inhibition.
There was a positive association between interpersonal prob-
lems and eating disorder psychopathology at baseline. Higher
levels of social inhibition predicted treatment noncompletion.
Conclusions: Our findings suggest that AN is associated with
a pattern of submissive and socially inhibited interpersonal
behavior which contributes to the maintenance of eating disor-
der pathology and interferes with treatment completion.

The aims of the present study were to determine the prev-
alence of non-suicidal self-injury (NSSI) in different Eating
Disorder (ED) groups and extreme Obesity (OBE), and to in-
vestigate whether NSSI in different ED/OBE groups co-occur
with impulsivity. We assessed 535 individuals (365 ED and
170 OBE patients) by means of a single item assessing life-
time NSSI and the Barratt Impulsivity Scale, which measures
different dimensions of impulsivity. The results showed that
19.1% of the ED patients engaged in at least one act of NSSI
during their life-time. NSSI was more prevalent in Bulimia Ner-
vosa, Binge Eating Disorder, Eating Disorder Not Otherwise
Specified compared to Anorexia Nervosa, Restrictive type and
extreme Obesity. Finally, ED/OBE patients who engaged in
NSSI scored significantly higher on the attentional, motor and
non-planning subscales than patients without NSSI. The im-
plications of these findings for the treatment of NSSI in binge/
purging ED patients are discussed.

Bariatric surgery is associated with significant improvement
in physical and mental health of the obese patients. However,
eating behaviors and related clinical symptoms compromise
treatment outcomes. This study investigates the point preva-
lence of disordered eating behaviors before surgery, at short
and long-term follow-up, and explores the impact of postop-
erative eating behaviors on weight outcomes. This cross-sec-
tional study-design compared a group of preoperative patients
(n= 176) and two postoperative groups, short-term (n=42)
and long-term (n=28), undergoing bariatric surgery. Assess-
ment included a clinical and diagnostic interview and a set
of self-report measures assessing eating symptomatology,
general distress, depression, impulsivity, body image, and
dysfunctional eating. Forty- seven (26,7% ) of the patients
evaluated at pre-surgery, six (14%) assessed at short-term,
