healthy subjects. The area under the ROC curve (AUC) for discrim-
inating between subjects with schizophrenia and healthy subjects
was 0.83. Cut point of 16 raw points is 86% sensitive and has 70%
specificity.
Conclusions The formof the tool that has been achieved as a result
of presented analyses suggests that this scale has a potential to
fulfill the assumed goals, which will be tested during continuing
validation studies.

Introduction In subjects with schizophrenia (SCZ), the disorga-
nization factor was found to be a strong predictor of real-life
functioning. “Conceptual disorganization” (P2), “difficulties in
abstract thinking” (N5) and “poor attention” (G11) are considered
core aspects of the disorganization factor, as assessed by PANSS. The
overlap of these itemswith neurocognitive functions is debated and
should be further investigated.
Aims Within the Italian network for research on psychoses study,
electrophysiological and neurocognitive correlates of the disorga-
nization factor and its component items were investigated.
Methods Resting state EEGs were recorded in 145 stabilized SCZ
and 69 matched healthy controls (HC). Spectral amplitude (SAmp)
was averaged in nine frequency bands. MATRICS consensus cog-
nitive battery (MCCB) was used for neurocognitive assessment.
Band SAmp differences and correlations with psychopathology and
MCCB scores were explored by global randomization statistics.
Results SCZ showed increased delta, theta, and beta1 and
decreased alpha2 SAmp. A negative correlation between alpha1
and disorganization was observed in SCZ. At the item level, only
N5 showed this correlation. MCCB neurocognitive composite was
associated with P2 and N5 but not with alpha1 SAmp.
Conclusions Our findings suggest an heterogeneity of the disor-
ganization dimension and a partial overlap with neurocognitive
domains. The N5, “difficulties in abstract thinking”, had a unique
association with alpha1 SAmp, which is thought to be involved in
the formation of conceptual maps.

Introduction Previous data showed higher autistic traits in indi-
viduals with anorexia nervosa (AN) compared to healthy controls
(CTL). It is not known, however, whether this characteristic is
shared by other feeding and eating disorders (FEDs) or it is uniquely
associated to AN.
Objectives To compare autistic traits among individuals with AN,
bulimia nervosa (BN), binge eating disorder (BED) and CTL and to
investigate which specific dimensions differentiate one group from
another.
Methods A total of 241 FED patients (53 AN, 41 BN, 42 BED) and
105 CTLwere administered the autism-spectrumquotient (AQ), the
adult autism subthreshold spectrum (AdAS Spectrum), the Ritvo
autism and Asperger diagnostic scale 14-item (RAADS-14 Screen).
Results FED subjects reported higher AQ, AdAS spectrum and
RAADS-14 total and subscales scores compared to CTL (all P < .001).
No differences were found amongst AN, BN and BED subjects in
questionnaires’ total scores. BN group scored higher than AN in
the hyper-/hyporeactivity to sensory input domain of the AdAS
spectrum ( P < .001); AN group scored higher than BED in the atten-
tion switching domain of the AQ (P < .001), and BED group scored
lower than both AN and BN in the mentalizing deficit domain of the
RAADS-14 (all P < .001).
Conclusions We reported for the first time that not only AN but
also BN and BED patients show greater autistic traits compared to
CTL. Longitudinal studies are needed to confirm this preliminary
report and to elucidate whether autistic traits either precede, co-
occur or follow FEDs.

Introduction Both resilient coping strategies and the struc-
tural/functional characteristics of personal social networks are
considered important factors when facing adversity and the chal-
lenges inherent to the aging process.
Objectives To analyze the association between the configurations
of ego-centred networks and different levels of resilient coping in
a sample of elderly people.
Methods Quantitative, cross-sectional study comparing groups,
with 512 participants, mostly women (n = 325; 63.5%), married
(n = 264; 51.5%), with 76 years old in average (SD ± 7.6), and with
basic education (n = 261; 51%). We used a socio-demographic ques-
tionnaire, the IARSP-Elderly (personal social network assessment
tool) and the Brief Resilient Coping Scale for data collection.
Results We found different levels of resilient coping in our sam-
ple: low (50.4%); medium (38,7%); strong (10.9%). These three
levels of coping were associated with the composition of ego-
centred networks, namely the proportion of friends and colleagues
(P < 0.05), different perceived emotional support, reciprocity and
satisfaction with the network ( P < 0.05), frequency of contacts and
relationships’ durability (P < 0.05).
Conclusions Higher levels of coping are associated with a larger
proportion of friends in the network, whereas the familistic
networks are associated with low coping. Although participants in
our study revealed mainly kin comprised networks, these results
