RESUMEN
BACKGROUND: During the last decades we have seen a new focus on early treatment of psychosis. Several reviews have shown that duration of untreated psychosis (DUP) is correlated to better outcome. However, it is still unknown whether early treatment will lead to a better long-term outcome. This study reports the effects of reducing DUP on 5-year course and outcome. METHOD: During 1997-2000 a total of 281 consecutive patients aged >17 years with first episode non-affective psychosis were recruited, of which 192 participated in the 5-year follow-up. A comprehensive early detection (ED) programme with public information campaigns and low-threshold psychosis detection teams was established in one healthcare area (ED-area), but not in a comparable area (no-ED area). Both areas ran equivalent treatment programmes during the first 2 years and need-adapted treatment thereafter. RESULTS: At the start of treatment, ED-patients had shorter DUP and less symptoms than no-ED-patients. There were no significant differences in treatment (psychotherapy and medication) for the 5 years. Mixed-effects modelling showed better scores for the ED group on the Positive and Negative Syndrome Scale negative, depressive and cognitive factors and for global assessment of functioning for social functioning at 5-year follow-up. The ED group also had more contacts with friends. Regression analysis did not find that these differences could be explained by confounders. CONCLUSIONS: Early treatment had positive effects on clinical and functional status at 5-year follow-up in first episode psychosis.

OBJECTIVE: To see, if voluntary admission for treatment in first-episode psychosis results in better adherence to treatment and more favourable outcome than involuntary admission. METHOD: We compared consecutively first-admitted, hospitalised patients from a voluntary (n = 91) with an involuntary (n = 126) group as to psychopathology and functioning using Positive and Negative Syndrome Scale and Global Assessment of Functioning Scales at baseline, after 3 months and at 2 year follow-up. Moreover, duration of supportive psychotherapy, medication and number of hospitalisations during the 2 years were measured. RESULTS: More women than men were admitted involuntarily. Voluntary patients had less psychopathology and better functioning than involuntary patients at baseline. No significant difference as to duration of psychotherapy and medication between groups was found. No significant difference was found as to psychopathology and functioning between voluntarily and involuntarily admitted patients at follow-up. CONCLUSION: Legal admission status per se did not seem to influence treatment adherence and outcome.

OBJECTIVE: To identify predictors of non-remission in first-episode, non-affective psychosis. METHOD: During 4 years, we recruited 301 patients consecutively. Information about first remission at 3 months was available for 299 and at 2 years for 293 cases. Symptomatic and social outcomes were assessed at 3 months, 1 and 2 years. RESULTS: One hundred and twenty-nine patients (43%) remained psychotic at 3 months and 48 patients (16.4%) remained psychotic over 2 years. When we compared premorbid and baseline data for the three groups, the non-remitted (n = 48), remitted for <6 months (n = 38) and for more than 6 months (n = 207), duration of untreated psychosis (DUP) was the only variable that significantly differentiated the groups (median DUP: 25.5, 14.4 and 6.0 weeks, respectively). Three months univariate predictors of non-remission were being single, longer DUP, core schizophrenia, and less excitative and more negative symptoms at baseline. Two-year predictors were younger age, being single and male, deteriorating premorbid social functioning, longer DUP and core schizophrenia. In multivariate analyses DUP, negative and excitative symptoms predicted non-remission at 3 months, but only DUP predicted at 2 years. CONCLUSION: Long DUP predicted both 3 month and 2-year non-remission rates in first-episode psychosis.

OBJECTIVE: To compare outcome over 5 years for patients who participated in multi family groups (MFGs) to those who refused or were not offered participation. METHOD: Of 301 first episode psychotic patients aged 15-65 years, 147 participated in MFGs. Outcome was measured by drop-out rates, positive and negative syndrome scale (PANSS) symptom scores, and duration of psychotic episodes during the follow-up period. RESULTS: Multi family group participants had a significantly lower drop-out rates at 5-year follow-up than patients who did not participate. However, the MFG participants had significantly less improvement in PANSS positive and excitative symptoms and had significantly longer duration of psychotic symptoms during the follow-up period. CONCLUSION: Multi family groups appear to increase the chance of retaining patients in a follow-up study, but adjustment of the programme may be necessary with first episode psychosis patients to meet their needs better.

Quality of life (QoL) measures are increasingly recognized as necessary parts of outcome assessments in psychosis. The present paper is a comprehensive study of patients with first-episode psychosis where QoL is measured by the commonly used Lehman Quality of Life Interview (L-QoLI). The aim is to examine if the L-QoLI maintain its original structure when used in a group of patients with first-episode psychosis, and to investigate what determines global subjective QoL with a specific emphasis on premorbid adjustment, duration of untreated psychosis (DUP) and clinical symptoms. The study indicates that the psychometric properties of the L-QoLI do not change significantly when used in first-episode samples. The patients report subjective and objective QoL in the fair to good range, with only a moderate association between the objective and subjective measures. Poor global satisfaction is predicted by being single, abusing drugs, being depressed, having a diagnosis of psychotic affective disorder, having poor premorbid social adjustment and DUP over 10 weeks. The study supports the notion that patients with first-episode psychosis construct QoL in the same way as other groups, and that longer durations of compromised function at this stage produces poor satisfaction with life rather than a downward readjustment of expectations.

OBJECTIVE: This study examined whether duration of untreated psychosis can be shortened in patients with first episodes of DSM-IV schizophrenia spectrum disorders and whether shorted duration alters patient appearance at treatment. METHOD: Two study groups were ascertained in the same Norwegian health care sector: one from 1993-1994 with usual detection methods and one from 1997-1998 with early detection strategies that included education about psychosis. RESULTS: Patients with early detection had a shorter median duration of untreated psychosis by 21.5 weeks than patients with usual detection. The number with psychosis was greater in the early detection group; the number with schizophrenia was less. Early detection patients had more substance abuse and were younger, better adjusted premorbidly, and less ill. CONCLUSIONS: Early detection can shorten duration of untreated psychosis and help more patients when they are less severely ill. Given the devastation of psychosis, this is a significant treatment advance.

This one-year follow investigation is a sequel of a previous controlled review of the therapeutic results at conclusion of treatment in 348 patients. Only 286 completed the treatment and, of these, 191 (67%) attended the follow-up investigation. Three had committed suicide and the remainder defaulted or did not wish to participate. The population followed-up had slightly better therapeutic results and were slightly less socially and mentally stressed than the treated patients as a whole. One year after the conclusion of treatment, 78% had still improved and 64% of those who improved primarily had improved further in the course of the follow-up year and this held also true for 63% of those who did not improve originally. The durability of the primary improvement was found to be 82%. Age was connected with the therapeutic result, subsequent improvement and also the durability so that the result was poorer with increasing age. Numerous other parameters also suggested that treatment gives the best result in patients less firmly established in social and mental circumstances of life. The therapeutic result was independent of sex, type of treatment and duration of treatment. The considerable subjective and clinical improvement as regards general wellbeing and cessation or reduction of symptoms/problems were not associated with greater connection with employment or reduction of assistance from the local authority.

OBJECTIVE: To describe 1-year outcome in a large clinical epidemiologic sample of first-episode psychosis and its predictors. METHOD: A total of 301 patients with first-episode psychosis from four healthcare sectors in Norway and Denmark receiving common assessments and standardized treatment were evaluated at baseline, at 3 months, and at 1 year. RESULTS: Substantial clinical and social improvements occurred within the first 3 months. At 1-year 66% were in remission, 11% in relapse, and 23% continuously psychotic. Female gender and better premorbid functioning were predictive of less severe negative symptoms. Shorter DUP was predictive for shorter time to remission, stable remission, less severe positive symptoms, and better social functioning. Female gender, better premorbid social functioning and more education also contributed to a better social functioning. CONCLUSION: This first-episode sample, being well treated, may be typical of the early course of schizophrenia in contemporary centers.

OBJECTIVE: Long duration of untreated psychosis (DUP) is associated with poorer outcome. The TIPS study demonstrated that DUP can be reduced through early detection (ED). As quality of life (QoL) is associated with DUP it is expected that reduction of DUP leads to better QoL. METHOD: Consecutive first-episode patients with a DSM-IV diagnosis of non-organic, non-affective psychosis were included, 281 patients gave informed consent and 263 completed a full evaluation of QoL. RESULTS: There were no differences in subjective QoL between ED and No-ED groups attributable to reduction in DUP. There were significant bivariate differences in frequency of family and social contacts in favor of the ED group, but multivariate analyses indicated that these differences were based on differences in sample characteristics. CONCLUSION: Deterioration in QoL may precede overt symptom formation. Focus on functional loss in ED educational campaigns may identify risk subjects earlier in the course of the disorder.

OBJECTIVE: While findings are contradictory, many studies report that long Duration of Untreated Psychosis (DUP) correlates with poorer outcome in first episode psychosis. In an outcome study of first-episode psychosis, we compared the patients who refused to participate in a follow-along with those who consented to estimate the importance of this factor in sample recruitment bias. Our questions were: (i) What is the percentage of refusers? (ii) Are there systematic differences between refusers and consenters on DUP and/or other admission variables? (iii) What is the risk of refusal for different values of DUP? METHOD: In an unselected group of consecutively admitted patients we compared follow-along refusers and consenters on the following admission variables: sex, age, diagnostic group, substance abuse, being in-patient, coming from an early detection site and DUP. We conducted a logistic regression analysis with refusal as the outcome variable. RESULTS: Ninety-three of 397 patients (23%) were refusers. In univariate analyses the only significant difference was found for DUP. The median DUP for consenters was 10 weeks and for refusers 32 weeks. DUP remained significant when all independent variables were controlled for. CONCLUSION: DUP was significantly related to risk for refusal. For tests of the impact of DUP on outcome, this may introduce a type II error bias.

OBJECTIVE: To review the literature on early intervention in psychosis and to evaluate relevant studies. METHOD: Early intervention was defined as intervention in the prodromal phase (primary prevention) and intervention after the onset of psychosis, i.e. shortening of duration of untreated psychosis (DUP) (secondary prevention). RESULTS: We found few studies aimed at early intervention, but many papers discussing the idea at a more general level. We identified no studies that prove that intervention in the prodromal phase is possible without a high risk for treating false positives. We identified some studies aimed at reducing DUP, but the results are ambiguous and, until now, no follow-up data showing a positive effect on prognosis have been presented. CONCLUSION: Early intervention in psychosis is a difficult and important challenge for the psychiatric health services. At the time being reduction of DUP seems to be the most promising strategy. Intervention in the prodromal phase is more ethically and conceptually problematic.

OBJECTIVE: To identify and discuss methodological pitfalls that may help explain why many questions around early detection (ED) and duration of untreated psychosis (DUP) are still unsolved. METHOD: This paper concentrates on pitfalls in the following areas: sampling, measurement and data analyses. RESULTS: The main problems seem to be: SAMPLING: Referral bias, exclusion of patients, patient refusal, and patients lost to follow-up. MEASUREMENT: Reliability, which is particularly cogent for multisite investigations, and validity, which includes: Start of illness, start of psychosis, diagnoses, start of treatment, the relationship between ED and DUP and choice of outcome measures. Data Analyses: Overlooking threshold effects of DUP, improper control for baseline scores, and lack of control for confounders. CONCLUSION: Methodological pitfalls may bias ED studies. Several pitfalls are unavoidable, but proper design and quality assurance can reduce their impact. Researchers ought to identify the pitfalls, and to estimate and discuss their influence.
