We aimed to study the occurrence and predictors of medical students' mental health problems that required treatment.

Medical students from all Norwegian universities (N = 421) were surveyed in their first term (T1), and 3 (T2) and 6 (T3) years later. The dependent variable was “Mental health problems in need of treatment”. Predictor variables included personality traits, medical school stress and negative life events.

The lifetime prevalence of mental health problems was 15% at T1. At T2, of the 31% who reported problems during the first 3 years, a majority had not sought help. At T3, 14% reported problems during the preceding year. Adjusted predictors of problems at T2 were previous mental health problems (p < .001), low level of intensity personality trait (extraversion) (p < .01), reality weakness personality trait (p < .01), perceived medical school stress (p < .05) and negative life events (p < .05).

Mental health problems during the first 3 years were predicted by previous problems, personality, medical school stress and negative life events.

A third of the students reported mental health problems during the first 3 years. Intervention should focus on both individual problems and contextual stress.

There is highly replicated positive correlation between longer duration of untreated psychosis and poorer outcome

To study the effect of early intervention in first psychosis on one-year outcome using an historical quasi-experimental design

We compare the outcome of two samples of first-episode psychosis from the same healthcare district at different time periods. The historical control sample was assessed during 19931994, before the establishment of a system for early detection of psychosis. The experimental sample is the early detection sample in the Early Treatment and Intervention in Psychosis study assessed during 1997–2000

At 1-year follow-up, the early detection group was younger, had a smaller fraction of individuals with schizophrenia, had less severe negative and general symptoms and had more friends in the past year than the historical control group. No differences were found in clinical course (remission, relapse, continuously psychotic) or positive symptoms, but more patients in the early detection sample were treated as outpatients without hospitalisation

Early detection of schizophrenia in one healthcare sector is associated with less severe deterioration at 1 year

It is unclear whether an early detection programme increases or decreases the number of patients with a long duration of untreated psychosis (DUP), and whether these differ from other patients with a long DUP.

To investigate whether the number and characteristics of patients with a long DUP in the early detection programme differ from those with along DUP in the non-earlydetection programme.

We compared the number and characteristics of patients with a DUP $2 years in an early detection area and a non-early detection area.

The early detection programme recruited slightly fewer patients with a long DUP than the non-early detection programme. The patients in the early detection programme had lower PANSS scores, but more frequently had a deteriorating course of premorbid social functioning.

An early detection programme does not seem to drain a pool of previously undetected patients with a long DUP. The patients in the early detection programme seem to have a lower symptom level at baseline and to have had a deteriorating premorbid social course.

Early detection programmes aim to reduce the duration of untreated psychosis (DUP) by public education and by prompt access to treatment via active outreach detection teams.

To determine whether those with first-episode psychosis in an early detection healthcare area with existing referral channels differ from those who access care via detection teams.

Those with first-episode psychosis recruited via detection teams were compared with those accessing treatment via conventional channels, at baseline and after 3 months of acute treatment.

Patients recruited via detection teams are younger males with a longer DUP a less dramatic symptom picture and better functioning; however they recover more slowly, and have more symptoms at 3-month follow-up.

After establishing low threshold active case-seeking detection teams, we found clear differences between those patients entering treatment via detection teams v. those obtaining treatment via the usual channels. Such profiling may be informative for early detection service development.

Knowledge about premorbid development in psychosis can shed light upon theories about aetiology and schizophrenic heterogeneity, and form a basis for early detection initiatives.

To identify and validate patterns of premorbid functioning in first-episode psychosis.

The Premorbid Adjustment Scale was used to examine 335 patients.

Social and academic function constituted fairly independent dimensions. Cluster analysis identified groups varying both in level and course. Patients with a stable social course compared with a deteriorating one had a shorter duration of untreated psychosis, were older, had more friends and less negative symptoms. Good childhood academic function correlated with more education, more meaningful activities and better working memory. Patients with a stable academic course were older at admission.

Patterns of premorbid development suggest both neuro-developmental and neuroregressive pathways to illness.

The prevalence and course of mental disorders among Vietnamese refugees were studied, using a model including variables from different research traditions.

A consecutive community cohort of 145 Vietnamese boat refugees aged 15 and above were personally interviewed on their arrival in Norway and three years later.

Three years later, there was, unexpectedly, no decline in self-rated psychological distress (SCL-90-R), almost one in four suffered from psychiatric disorder and the prevalence of depression was 17.7% (Present State Examination). Female gender, extreme traumatic stress in Vietnam, negative life events in Norway, lack of a close confidant and chronic family separation were identified as predictors of psychopathology.

The effects of war and persecution were long-lasting, and compounded by adversity factors in exile. A uniform course of improvement in mental health after resettlement cannot be expected in all contexts. The affected refugees need systematic rehabilitation.
