ing problem levels while controlling for pre-treatment trajectory,
and to seek evidence of a dose-response relationship.
Methods Six-year follow up data were used from the Tracking
Adolescents’ Individual Lives Survey (TRAILS). We identified ado-
lescents with a clinical level of problem behaviour on the Child
Behaviour Checklist or Youth Self Report and first SMHT between
the ages 13 and 16. Adolescents with a clinical level of problem
behaviour but without SMHT use served as control group. A psychi-
atric case register provided data on number of treatment contacts.
Using regression analysis, we predicted the effect of treatment on
post-treatment problem scores.
Results Treated adolescents more often had a (severe) diagno-
sis than untreated adolescents. Pre-treatment trajectories barely
differed between treated and untreated adolescents. Treatment
predicted an increase in follow-up problem scores, regardless of
the number of sessions.
Conclusion The quasi-experimental design calls for modest con-
clusions. Wemight however need to take a closer look at real-world
service delivery, and invest in developing treatments that can
achieve sustainable benefits.

Introduction Perceived competence (PC) is a self-perception of an
individual in its capabilities and ability to control his environment.
It is posited to orient individuals to the possibility of success and to
facilitate the adoption of approach goals.
Objectives We aimed to assess the PC of adolescents engaged in
prosocial activities and to determine factors that influence it.
Methods We led a transversal study, over four months, from June
until September 2016. It included 90 adolescents aged 14–20 years
and members of voluntary association in Sfax (Tunisia). PC was
assessed using the “perceived competence in life domains” (PCLD)
for the life spheres of leisure, interpersonal relationships, school,
and general domains.
Results The average age of participants was 16 (14 to 20 years).
The samplewas female-dominated (53%). All participantswere sec-
ondary school pupils. Almost 70%were from a high socio-economic
level and over 60% had parents’ high level of education.
The mean scores of PC ranged from 19 (SD = 5.4) in leisure domain
to 16 (SD = 4) in interpersonal relationships domain. PC was signifi-
cantly correlatedwith socio-economic level (P = 0.00), participating
in sports and extra- curricular activities (P = 0.00), academic profi-
ciency (P = 0.01) and smoking (P = 0.00).
Conclusion Overall, our results evidenced the positive self-
perception of competence among adolescents having prosocial
activities. It indicated that high socio-economic level, participating
in sports and extra-curricular activities and smoking were enhanc-
ing factors of adolescents PC.

Introduction The occurrence of acute leukemia (AL) in childhood
causes a profound upheaval in the child itself and also within his
family. Exposure to this test could contribute to the emergence of
anxiety.
Objective Ourwork aims to describe the characteristics of anxiety
in this population during the management of the AL.
Patients and methods Our study, still in progress, is prospec-
tive and conducted among 20 children hospitalised in hematology
department of UMC Hedi Chaker Sfax (Tunisia) during the year
2015–2016. It is performed in two times. The anxiety was assessed
using the STAI scale.
Preliminary results The average age of our population is 7 years
(minimum age = 4 years, maximum age = 11 years). The majority
of our patients come from urban areas (76.9% of cases). About their
sibling rank, they aremostly the youngest in 53.8% of cases, the old-
est in 30.8% of cases and juniors in 7.7% of cases. The most common
diagnosis is the lymphoblastic B AL (46.2% of cases).
Referring to the STAI scale, 30% of our patients were anxious and
had high scores during the first evaluation. Then, the anxiety level
attenuates gradually duringmanagement period and only 15%were
anxious at the 2nd evaluation time.
Conclusion Several factors such as hospitalisation, diagnosis
announcement and cancer treatment contribute to the triggering
and maintaining of anxiety. Early detection of anxiety and the good
listening between the care team and the parents could appease the
high level of anxiety and ensure better management.

Introduction Most parents to childrenwithAutismSpectrumDis-
order (ASD) can report concerns about their child’s development
within the first year of life. In spite of this, children with ASD
are rarely diagnosed before the age of 3–4 years. Early identifica-
tion allows early intervention, which seems to be substantial for
improvement of core behavioural symptoms in children with ASD.
The Child Behaviour Checklist for ages 1½ to 5 (CBCL/1½–5) have
shown promising utility for early detection of children with ASD.
Objectives This study will estimate the positive predictive value
of CBCL/1½–5 Pervasive Developmental Problems (PDP) scale in a
2 phase screening study. Furthermore, it will analyse the stability
of the CBCL/1½–5 PDP-score in pre-school children from 2½ to 5
years.
Aims The present study aims to validate CBCL/1½–5 for early
screening of ASD in a general population sample.
