Results: The sample included four female and one male subject,
with BMI at baseline 42,815,66. The results of BMI and EWL over
time are described in Table 1. A significant statistical difference was
found between BMI at baseline and at T6, T12, T24, and T36
(p<0,05). EWL was higher at T12 ( compared with T6), but not
different from other measurements. PANSS scores at the baseline
were 7,7 1,6 for a positive domain, 8,7 2,3 for a negative
domain, and 19,2 6 for general psychopathology, with no stat-
istically significant differences during the follow-up.
Conclusions: Despite the small sample, bariatric surgery has been
shown a safe and efficient refractory obesity treatment in patients
with schizophrenia.
Disclosure: No significant relationships.

Introduction: The Interpersonal Needs Questionnaire (INQ-15)
and the Acquired Capability for Suicide Scale - Fearlessness About
Death (ACSS-FAD) have been introduced to evaluate the theoret-
ical constructs posit by Joiner’s Interpersonal Psychological Theory
of Suicide (IPTS).
Objectives: The present study aimed to evaluate the psychometric
properties of the INQ-15 (which measures Thwarted Belonging-
ness, TB, and Perceived Burdensomeness, PB) and the ACSS-FAD
(measurement of Fearlessness About Death, FAD, dimension of the
acquired capability) in a population of Italian university students.
Methods: Since there was no Italian version of the ACSS-FAD, we
have translated it through an accurate multistage procedure. ACSS-
FAD and INQ-15 have been administered to a sample of 1,665
Italian university students. We analyzed the factorial structure of
the INQ-15 and the ACSS-FAD, their reliability, criterion, conver-
gent and discriminant validity.
Results: Principal Component Analysis confirmed a two-dimensional
structure for INQ-15 and a one-factor structure for ACSS-FAD.
Internal consistency reliability of the scales was good, respectively
TB: α=.85; PB: α=.90;and FAD: α=.85. The INQ-15 demonstrated
concurrent associations with suicidal ideation, while the ACSS-FAD
with a history of suicidal planning/suicide attempt. Convergent and
discriminant validity were also in line with previous studies.
Conclusions: Both INQ-15 and ACSS-FAD appropriately capture
the respective constructs, proving to be valid measures for the
assessment of suicide risk factors among Italian university students
according to the IPTS. The valuable psychometric properties of the
two scales established with this study in the Italian context encour-
ages their use to advance the clinical understanding and prevention
of suicide.
Disclosure: No significant relationships.

Introduction: Previous research highlighted that adolescents with
attention-deficit/hyperactivity disorder (ADHD) are four times as
vulnerable to suicidal behavior as the healthy population. Maladap-
tive perfectionism is also viewed as an important risk factor for
suicide. Yet, there are no studies which focused on the relationship
between perfectionism and suicide among adolescents with ADHD.
Objectives: The objective of the present study was to explore if
perfectionism may be a risk factor for suicidal behavior in adoles-
cents with ADHD.
Methods: The clinical group was recruited from outpatient clinics,
while the non-clinical group was recruited from high schools
around Hungary. The clinical group’s inclusion criterion was
ADHD diagnoses, while the non-clinical group required the
absence of any current or past psychiatric treatment or diagnoses.
Results: In the ADHD group 88 adolescents participated, and
96 adolescents participated in the non-clinical group. There was
no difference regarding the level of perfectionism in the groups,
except one dimension of perfectionism, which is ‘Organization’.
The ADHD group had significantly higher level of suicidal behavior
than the control group ((χ2 (1) =11.222, p < .001, V =0.25).
Among the ADHD group adaptive perfectionism was significantly
negatively correlated with suicidal behaviour.
