Objectives The aim of this study is to determine the extent
to which self-, parent- and teacher-reported problem behavior
predict secondary care in adolescence and to what extent the infor-
mants’ relative importance changes over time.
Methods Data from the Dutch community-based cohort study
tracking adolescents’ individual lives survey (TRAILS) were linked
to administrative records of secondary care from 2000 (age 9)
to 2011 (age 21). Internalizing and externalizing problems were
assessed using the youth self-report, child behavior checklist and
teacher checklist of psychopathology at ages 11, 13 and 16, and the
adult self-report at age 19.
Results The annual incidence of secondary care fluctuated
between 1.3% and 2.4%. In Cox regression analyses that adjusted for
sociodemographic covariates and problem behavior, internalizing
problems but not externalizing problems predicted secondary care.
Secondary care between the ages 11 to 13 years was predicted best
by teachers, between the ages 13 to 16 by parents, and between the
ages 16 to 21 by adolescents.
Conclusions The relative importance of informants for predicting
secondary care shifts over time, which suggests that each infor-
mant is the driving force behind secondary care at a different phase
of adolescence. The treatment gap may be reduced by improving
problem recognition of teachers in secondary education and by
educating young adults about mental health problems.

Introduction An increasing number of young people in Sweden
are diagnosed with mental disorders and there appears to be sig-
nificant gender differences in disease pattern.
Objective Tomore thoroughly characterize the increase inmental
disorders among young people with focus on gender differences.
Aim To increase the knowledge of age and sex-specific trends in
incidence and prevalence rates of mental disorders among children
and adolescents.
Method Data on psychiatric diagnoses for the last 10 years were
obtained from Swedish national registers held by the National
Board of Health and Welfare in Sweden.
Results Neuropsychiatric, depressive and anxiety disorders have
increased markedly among young people the last decade. In
addition, men are increasingly diagnosed with substance-related
disorders whereas women with borderline personality disorder.
Conclusion The increase in mental disorders among young peo-
ple is marked and disease affects men and women differently.
Because of greater awareness today, some conditions like ADHD
aremore frequently diagnosed. However, the increase indepressive
and anxiety disorders appears genuine and represents an additional
challenge.

Introduction Compared to 16–40-year-olds, 8–15-year-olds of
the community reported higher frequencies of perceptual and
lesser clinical significance of non-perceptual attenuated psychotic
symptoms (APS).
Objectives/aims We examined if a similar age effect is present in
a clinical never-psychotic sample (n = 133) referred to a specialized
service for clinical suspicion of developing psychosis.
Methods APS and brief intermittent psychotic symptoms (BIPS)
were assessed using items P1-3 and P5 (non-perceptual) and
P4 (perceptual) of the structured interview for psychosis-risk
syndromes, current axis-I disorders with the mini-international
neuropsychiatric interview and psychosocial functioning with the
Social and Occupational Functioning Assessment Scale (score < 71
indicative of at least some difficulty in social, occupational, or
school functioning).
Results Overall, 64% reported APS (61%) or BIPS (7%); any per-
ceptual APS/BIPS was reported by 43% and any non-perceptual
APS/BIPS by 44%. In correspondence to the results of the community
study, perceptual but not non-perceptual APS/BIPS were signifi-
cantly more frequent in younger age groups below the age of 16
(8–12 yrs: OR = 4.7 (1.1–19.5); 13–15 yrs: OR = 2.7 (0.9–7.7); 20–24-
year-olds as reference group). An age effect of APS/BIPS on presence
of any current axis-I disorder (59%) or functional difficulties (67%)
could not be detected. Yet, when APS onset requirements weremet,
the likelihood of a psychiatric diagnosis increased significantlywith
advancing age.
Conclusion Overall, the replicated age effect on perceptual APS
in this clinical sample highlights the need to examine ways to
distinguish clinically relevant perceptual APS fromperceptual aber-
rations likely remitting over the course of adolescence.

Introduction Limited clinical relevance of attenuated psychotic
symptoms before the turn from early to late adolescence, i.e., age
15/16, was reported.
Objective This emphasizes the potentially important role of neu-
rodevelopmental aspects in the early detection of psychoses.
Aims We examined the age effect on prevalence and clinical rele-
vance of 14 cognitive and perceptive basic symptoms (BS) included
in risk criteria of psychosis in a random representative 8–40-year-
old community sample (n = 689).
