Background Optimizing psychiatric assessments could help to
standardize the use of structured instruments in clinical practice. In
recent years, several research groups have applied Computerized
Adaptive Tests (CATs) to simplify assessments in depression, anxi-
ety and also suicidal behaviors. We aimed to construct a shortened
test to classify suicide attempters using a decision tree method-
ology that allows the integration of relevant clinical information,
namely the history of past suicide attempts, in the construction of
the test.
Methods The sample was composed of 902 adult participants in
three subsamples: first-time suicide attempters, psychiatric inpa-
tients that never attempted suicide and healthy controls. The
performance of a decision tree built using the items of a previously
developed scale for suicidal risk was examined. The history of past
suicide attempts was used to separate patients in the decision tree.
The data was randomly divided in a training set and a test set. The
test set, that contained 25% of the data, was used to determine the
accuracy of the decision tree. Twenty-five cross-validations of this
set up were conducted.
Results The first four items of the decision tree classified correctly
81.4% of the patients.
Conclusion As a result of a methodology based on decision trees
that, contrary to CATs, can incorporate relevant information in
building the test we were able to create a shortened test capa-
ble of separating suicidal and non-suicidal patients. Using all the
information that is available improves the precision and utility of
instruments adapted for psychiatric assessments.

Introduction Suicide causes 1.4% of deaths worldwide. Twenty
times more frequent, suicide attempts entail an important source
of disability and of psychosocial and medical resources use.
Objective To describe main socio-demographical and psychiatric
risk factors of suicide attempters treated in a general hospital’s
emergency room basis.
Aims To identify individual features potentially useful to improve
both emergency treatments and resource investment.
Methods A descriptive study including data from 2894 patients
treated in a general hospital’s emergency room after a suicidal
attempt between years 2006 and 2014.
Results Sixty-nine percent of the population treated after an
attempted suicide were women. Mean age was 38 years old. Sixty-
six percent had familiar support; 48.5% had previously attempted
a suicide (13% did not answer this point); 72.6% showed a personal
history of psychiatric illness. Drug use was present in 38.3% of the
patients (20.3% did not answer this question); 23.5% were admit-
ted to an inpatient psychiatric unit. Medium cost of a psychiatric
hospitalization was found to be 4900 euros.
Conclusion This study results agree with previously reported
data. Further observational studies are needed in order to bear out
these findings, rule out potential confounders and thus infer and
quantify causality related to each risk factor.

Introduction Suicide behavior constitutes a public health prob-
lem worldwide. It deserves epidemiological investigation regard-
ing “best clinical practices”, and it is fundamental since the patient’s
first observation at psychiatric emergencies services. These are the
ideal practices to start suicide prevention, and prevent further sui-
cidal behavior. The improvement of healthcare quality includes the
adoption of clinical guidelines, which support medical care since
the emergencies services. The lack of specific instruments to eval-
uate suicidal risk urges the scientific community to create them.
Aims The authors aim to discuss the advantages and limitations
of the application of these kinds of instruments, and the creation of
models based in scientific evidence available.
Discussion From multiple available studies, the Modified Sad-
Persons Scale (MSPS) seems to be one of the most scientifically
used in literature, as well as in epidemiological studies of suicide
attempts and their repetition, either by nonfatal or fatal attempts.
However, even this scale has been questioned by experts, and the
lack of specific and sensible tests towards suicide behavior and
risk of suicide attempts raises the importance of the need of fur-
ther investigation towards this area. This evidence would then help
the clinician in his work at emergencies wards and provide better
healthcare towards preventing new suicide attempts.

Patterns of suicide and suicidal behavior vary among different cul-
tures. In Albania and in Korc¸ a region has a relatively high number of
suicides and behavior related to for a long period of time related to
the transition, the changes that have occurred and occur in Albania,
