Introduction Population attributable fraction (PAF) represents
the proportion of treatment failure, which could be avoided, if the
individuals at high risk were similar to the individuals at low risk.
The PAF, however, has not been available for repeated measures
designs.
A relatively prevalent and strong risk factor for many adulthood
disorders, such as depression and anxiety, are adversities and trau-
mas experienced in childhood. Little is, however, known of their
implications for common treatments such as psychotherapy.
Objectives To develop PAF for repeated measures, and to provide
a useful tool in various research fields to provide decision-makers
results, which are easier to interpret.
This study will examine the relative importance of different child-
hood traumas as predictors of psychotherapy outcome in a patient
population with depressive and anxiety disorders.
Methods PAF was calculated using generalized linear mixed
models and Bayesian predictive distributions.
The data is based on 326 outpatients, randomized in one long-term
and two short-termpsychotherapies by theHelsinki Psychotherapy
Study. Patientswere assessed up to 10 times during a 5-year follow-
up. A combination of psychiatric symptomsmeasured, is used as the
outcome measure.
Results The repeated measures PAF will provide a useful aggre-
gate measure over the follow-up time and over the patient
population.
Conclusions The repeated measures PAF will provide insight on
the relative importance of the different domains of childhood
traumas on therapy outcome. Associations of individual-level risk
factors do not provide guidelines for policy decisions, which should
acknowledge also prevalences of the risk factors in the patient pop-
ulation.

Introduction/objectives The available literature suggests that
treatments and health services for psychosis are considered to be
poorly organized and highly variable. Little is known, however,
about how inpatient care is provided to individuals experiencing
early psychosis. To facilitate quality improvement activities, we
characterized the care this patient group receives in an inner city
hospital.
Methods We performed chart reviews of individuals admitted to
psychiatric inpatient units at St. Paul’s Hospital, Vancouver, British
Columbia between 01/04/2014 and 31/03/2016. Those who were
17–25 years of age and hospitalized for psychotic symptoms at the
time of admission were included. Demographic and health service
use were summarized using descriptive characteristics.
Results We identified 73 inpatients (mean age = 22; males = 78%;
Caucasian = 41%) that met study inclusion criteria, having a com-
bined total of 102 care episodes and an average length of stay
of 30.7 days (median = 18; min = 3; max = 268). Half of the care
episodes were repeat admissions, with up to 30% of the patients
readmitted within 28 days of discharge. Physical and mental status
examinations (MSE) were performed in virtually all care episodes,
although frequency is low (31.4% had daily physical examinations
and 18.6% had MSE every nursing shift). In 49% and 50% of care
episodes, patients were given oral antipsychotics and discharged
on depot medications. Even when indicated, not all care episodes
had follow-up appointments (60%) or referrals to income assistance
(35%), community mental health teams (61%), and housing support
(38%).
Conclusions Specific programs are needed to address current
gaps in inpatient care for patients with early psychosis.

connections” – A short-term,

Objectives Mental health conditions (MHC) have been associated
with restrictions in daily life participation and functioning affect-
ing health and well-being. Substantial numbers of people with
MHC experience hospitalizations, however, there is limited evi-
dence supporting functional interventions in the in-patient setting
to promote recovery. The OC is an intervention implemented dur-
ing sub-acute hospitalization, which attempts to promote activity
and participation of people with MHC, both during the in-patient
stay and upon return to the community, with a view to enabling
recovery. To facilitate its implementation, we investigate the OC
effectiveness.
Aims Investigate theOC contribution to cognition, symptoms and
functional capacity among inpatients with schizophrenia.
Methods This is a quasi-experimental, prospective, pre/post-
designed study with convenience sampling. Inpatients with
schizophrenia were enrolled into the study group participating in
the OC intervention (n = 16); or the control group participating in
hospital treatment as usual (n = 17). The study participants com-
pleted evaluations at baseline and at discharge or after 10 weeks
with: Neurocognitive State Examination, Trail Making Test, Ray
Complex Figure, and Category Fluency Test for aspects of cogni-
tion; Positive and Negative Syndrome Scale for symptoms severity,
and Observed Tasks of Daily Living-Revised for functional capacity.
