Values in First-Episode Schizophrenia.

OBJECTIVE: Functional impairment continues to represent a major challenge in schizophrenia. Surprisingly, patients with schizophrenia report a level of happiness comparable with control subjects, even in the face of the prominent functional deficits, a finding at odds with evidence indicating a positive relation between happiness and level of functioning. In attempting to reconcile these findings, we chose to examine the issue of values, defined as affectively infused criteria or motivational goals used to select and justify actions, people, and the self, as values are related to both happiness and functioning. METHODS: Fifty-six first-episode patients in remission and 56 healthy control subjects completed happiness and values measures. Statistical analyses included correlations, analysis of variance, structural equation modelling, and smallest space analysis. RESULTS: Results indicated that patients with schizophrenia placed significantly greater priority on the value dimensions of Tradition (P = 0.02) and Power (P = 0.03), and significantly less priority on Self-direction (P = 0.007) and Stimulation, (P = 0.008). CONCLUSIONS: Essentially, people with schizophrenia place more emphasis on the customs and ideas that traditional culture or religion provide in conjunction with a decreased interest in change, which is at odds with the expectations of early adulthood. This value difference could be related to functional deficits. To this point, we have assumed that people hold to the same values that guided them before the illness' onset, but this may not be the case. Our study indicates that values differ in people with schizophrenia, compared with control subjects, even early in the illness and in the face of symptomatic remission.

Characterization and prediction of individual functional outcome trajectories in schizophrenia spectrum disorders (PREDICTS study): Study protocol.

Schizophrenia spectrum disorders (SSDs) are associated with significant functional impairments, disability, and low rates of personal recovery, along with tremendous economic costs linked primarily to lost productivity and premature mortality. Efforts to delineate the contributors to disability in SSDs have highlighted prominent roles for a diverse range of symptoms, physical health conditions, substance use disorders, neurobiological changes, and social factors. These findings have provided valuable advances in knowledge and helped define broad patterns of illness and outcomes across SSDs. Unsurprisingly, there have also been conflicting findings for many of these determinants that reflect the heterogeneous population of individuals with SSDs and the challenges of conceptualizing and treating SSDs as a unitary categorical construct. Presently it is not possible to identify the functional course on an individual level that would enable a personalized approach to treatment to alter the individual's functional trajectory and mitigate the ensuing disability they would otherwise experience. To address this ongoing challenge, this study aims to conduct a longitudinal multimodal investigation of a large cohort of individuals with SSDs in order to establish discrete trajectories of personal recovery, disability, and community functioning, as well as the antecedents and predictors of these trajectories. This investigation will also provide the foundation for the co-design and testing of personalized interventions that alter these functional trajectories and improve outcomes for people with SSDs.

Electrophysiological evidence for primary semantic memory functional organization deficits in schizophrenia.

N400, an event-related brain potential (ERP) waveform elicited by meaningful stimuli, is normally reduced by stimulus repetition (N400 repetition priming), and relatedness between the eliciting stimulus and preceding ones (relatedness priming). Schizophrenia patients' N400 relatedness priming deficits suggest impairment in using meaningful prime stimuli to facilitate processing of related concepts in semantic memory. To examine whether this deficiency arises from difficulty activating the prime concept per se, as indexed by reduced N400 repetition priming; or from impaired functional connections among concepts in semantic memory, as reflected by reduced relatedness priming but normal repetition priming; we recorded ERPs from 16 schizophrenia patients and 16 controls who viewed prime words each followed at 300- or 750-ms stimulus-onset asynchrony (SOA) by an unrelated, related or repeated target word, or a nonword, in a lexical-decision task. In both groups, N400s were largest (most negative) for unrelated, intermediate for related, and smallest for repeated targets. Schizophrenia patients exhibited subnormal N400 relatedness priming at the 300-ms SOA, but normal repetition priming at both SOAs, suggesting that their impairment in using prime words to activate related concepts results from abnormal functional connections among concepts within semantic memory, rather than inability to activate the prime concept itself.

Do anxiety and depression symptoms moderate the effect of motivational enhancement therapy as a pretreatment to dialectical behaviour therapy skills training? A follow-up analysis of a pilot randomised controlled trial for youth.

AIM: We conducted a follow-up analysis of a pilot randomised controlled trial to examine whether baseline depression and anxiety symptoms moderated the impact of a motivational enhancement therapy (MET) pretreatment to dialectical behaviour therapy skill training (DBT-ST) for EA experiencing emotion dysregulation. METHODS: All participants completed a 12-week DBT-ST group intervention and participants in the MET/DBT-ST condition also completed a 4-week group MET pretreatment. Nineteen MET/DBT-ST participants and 26 DBT-ST only participants completed the treatment as per protocol. RESULTS: Baseline anxiety and depression symptoms moderated the impact of the MET pretreatment for participants' reductions in emotion dysregulation and psychological distress, respectively, at a 3-month follow-up: participants with more severe baseline symptoms benefited more from the pretreatment. However, baseline symptoms did not moderate the effect of MET immediately after treatment. CONCLUSIONS: These results identified for whom MET is most effective as a pretreatment for DBT-ST amongst a heterogenous sample of EA in a real-world setting.

You say "schizophrenia" and I say "psychosis": Just tell me when I can come off this medication.

Individuals experiencing a first episode of psychosis are likely to respond well to treatment with antipsychotic medications. Of those treated for a first episode of schizophrenia, three out of four can expect to achieve remission. The question of how long antipsychotic medication should be continued has been a topic of heated debate in the field. Longitudinal studies of individuals diagnosed with a first episode of psychosis have reported that as many as 30% may be able to come off of medications without relapsing while treatment discontinuation studies have found that very few patients remain in remission off of medication. This paper reviews the literature on relapse rates following a first episode of schizophrenia and identifies factors that contribute to the discrepancies in the rates reported. These factors include sampling considerations, the distribution of psychiatric diagnoses, the duration of follow-up, the rate of medication discontinuation and the criteria used to define illness recurrence. We propose that individuals for whom the diagnosis of their first psychotic episode is determined with ongoing follow-up to be due to schizophrenia are at extremely high risk of relapse and should be advised to continue antipsychotic medication for the long-term. Those whose first episode of psychosis is determined to be due to other causes are also at high risk of illness recurrence off medications. Recommendations for maintenance treatment should be tailored to reflect the risk of relapse and sequelae of relapse associated with specific causes of first episode psychosis.

Rethinking service design for youth with mental health needs: The development of the Youth Wellness Centre, St. Joseph's Healthcare Hamilton.

AIM: This article describes the development and design of the Youth Wellness Centre (YWC), an innovative, youth-friendly centre providing mental health and addiction services for emerging adults aged 17 to 25 in Hamilton, Canada. We also report on demographic and clinical characteristics of clients to evaluate how the YWC is serving populations at increased risk of developing mental disorders. METHODS: Data were extracted from clinic databases for 1520 youth at the YWC between March 2015 and 2018 to report on demographic characteristics, clinical profiles, primary presenting problems, service use and overall satisfaction with services. RESULTS: Marginalized groups, particularly street-involved individuals and LGBTQ+ youth, are highly represented at the YWC, keeping with the centre's mandate of reaching at-risk populations. Youth at the YWC carry significant mental health burdens, with 80.8% having a history of suicidal ideation and 32.8% having a history of a substance use disorder. The primary route of referral is self-referral and the number of new clients has increased by nearly 20% in the first 3 years of operations. Overall satisfaction with the centre is on par with or slightly above provincial averages. CONCLUSIONS: The YWC was developed to meet the mental health needs of transition-aged youth in Hamilton by providing early intervention, system navigation and transition services. The success of the YWC in reaching high-risk youth is demonstrated by the significant proportion of clients reporting demographic and clinical risk factors associated with increased risk for development of mental disorders. The increasing referrals to the YWC highlight the ongoing need for similar services.

Motivational Enhancement as a Pretreatment to a Transdiagnostic Intervention for Emerging Adults with Emotion Dysregulation: A Pilot Randomized Controlled Trial.

OBJECTIVE: New approaches are needed to help the large number of emerging adults (EA) presenting with early-stage mental health problems. The goal of this pilot study was to carry out a randomized controlled trial to investigate whether motivational enhancement therapy (MET) improved the treatment effects of a 12-week psychological intervention, Dialectical Behaviour Therapy Skills Training (DBT-ST), for EA presenting in the early stages of mental health difficulties. Participants were recruited from the Youth Wellness Centre at St. Joseph's Healthcare Hamilton and McMaster University's Student Wellness Centre in Hamilton, Canada. METHODS: Seventy-five participants were randomized to receive MET followed by DBT-ST or to DBT-ST alone. We assessed psychological distress, emotion dysregulation, and depression and anxiety symptoms as outcomes. RESULTS: We found that both treatment groups had significant reductions in emotional dysregulation, psychological distress, depression, and anxiety at post-treatment and at the three-month follow-up. Participants assigned to MET pre-treatment experienced greater improvement in psychological distress at the end of treatment. CONCLUSION: This pilot study provides preliminary evidence of the potential augmentation of DBT-ST using MET in a real-world setting. Future studies should examine whether MET uniquely augments DBT-ST through the use of a comparable pre-treatment control group.

OBJECTIF: De nouvelles approches sont nécessaires pour aider le grand nombre d'adultes émergeants (AE) qui présentent des problèmes de santé mentale au stade précoce. La présente étude pilote avait pour but d'exécuter un essai randomisé contrôlé afin de rechercher si la thérapie d'amélioration motivationnelle (TAM) améliorait les effets du traitement d'une intervention psychologique de 12 semaines, soit la formation technique à la thérapie comportementale dialectique (FT-TCD), pour les AE qui présentent les premiers stades de difficultés de santé mentale. Les participants ont été recrutés au centre Youth Wellness de St. Joseph's Healthcare Hamilton et au centre Student Wellness de l'Université McMaster, à Hamilton, Canada. MÉTHODES: Soixante-quinze participants ont reçu au hasard la TAM suivie de la FT-TCD ou uniquement la FT-TCD. Nous avons évalué la détresse psychologique, la dérégulation émotionnelle, et les symptômes dépressifs et anxieux comme résultats. RÉSULTATS: Nous avons constaté que les deux groupes du traitement avaient des réductions significatives de la dérégulation émotionnelle, de la détresse psychologique, de la dépression et de l'anxiété au post-traitement et au suivi de 3 mois. Les participants affectés à la TAM de prétraitement ont eu une plus grande amélioration de la détresse psychologique en fin de traitement. CONCLUSION: Cette étude pilote offre des données probantes préliminaires de l'augmentation potentielle de la FT-TCD utilisant la TAM dans une situation réelle. Les futures études devraient examiner si la TAM n'augmente seulement la FT-TCD que par le recours à un groupe témoin prétraitement comparable.

Understanding and Managing Treatment Adherence in Schizophrenia.

Schizophrenia is a chronic, debilitating and costly illness. The course of illness is often exacerbated by relapses which are associated with negative outcomes including rehospitalisation. The most important risk factor associated with relapse is medication nonadherence. Medication nonadherence is not specific to schizophrenia and is an issue across all of medicine. The objective of this paper is to present a narrative review which synthesizes the rates and predictors of medication nonadherence, as well as associated interventions, across schizophrenia, first episode psychosis and general medicine. Given the breadth of these topics, this paper does not aim to present a complete review of the data but rather a concise synthesis of several lines of research in order to provide a general framework for approaching this important topic. Overall, this paper identifies that rates and risk factors of nonadherence in schizophrenia are similar to those reported in general medicine. Rates of adherence are estimated at 50% for both. Predictors of nonadherence were also quite similar between various illnesses, with lack of insight, poor family support and substance abuse often being highlighted. Well studied approaches of improving adherence include simplifying medication regimens, psychoeducation, engaging family support and use of long-acting injectable antipsychotics. Emerging interventions included text-message reminders, financial incentives and MyCite technology. Additionally, several evidence based interventions were identified in general medicine that may have applicability in schizophrenia and first episode psychosis. Lastly, avenues of future research were identified including the need to further characterize the dichotomy between adherence, partial adherence and nonadherence.

Does relapse contribute to treatment resistance? Antipsychotic response in first- vs. second-episode schizophrenia.

Although some studies have suggested that relapse may be associated with antipsychotic treatment resistance in schizophrenia, the number and quality of studies is limited. The current analysis included patients with a diagnosis of first-episode schizophrenia or schizoaffective disorder who met the following criteria: (1) referral to the First-Episode Psychosis Program between 2003 and 2013; (2) treatment with an oral second-generation antipsychotic according to a standardized treatment algorithm; (3) positive symptom remission; (4) subsequent relapse (i.e., second episode) in association with non-adherence; and (5) reintroduction of antipsychotic treatment with the same agent used to achieve response in the first episode. The following outcomes were used as an index of antipsychotic treatment response: changes in the brief psychiatric rating scale (BPRS) total and positive symptom scores and number of patients who achieved positive symptom remission and 20 and 50% response. A total of 130 patients were included in the analyses. Although all patients took the same antipsychotic in both episodes, there were significant episode-by-time interactions for all outcomes of antipsychotic treatment response over 1 year in favor of the first episode compared to the second episode (50% response rate: 48.7 vs. 10.4% at week 7; 88.2 vs. 27.8% at week 27, respectively). Although antipsychotic doses in the second episode were significantly higher than those in the first episode, results remained unchanged after adjusting for antipsychotic dose. The present findings suggest that antipsychotic treatment response is reduced or delayed in the face of relapse following effective treatment of the first episode of schizophrenia.

Investigating service features to sustain engagement in early intervention mental health services.

AIM: To understand what service features would sustain patient engagement in early intervention mental health treatment. METHODS: Mental health patients, family members of individuals with mental illness and mental health professionals completed a survey consisting of 18 choice tasks that involved 14 different service attributes. Preferences were ascertained using importance and utility scores. Latent class analysis revealed segments characterized by distinct preferences. Simulations were carried out to estimate utilization of hypothetical clinical services. RESULTS: Overall, 333 patients and family members and 183 professionals (N = 516) participated. Respondents were distributed between a Professional segment (53%) and a Patient segment (47%) that differed in a number of their preferences including for appointment times, individual vs group sessions and mode of after-hours support. Members of both segments shared preferences for many of the service attributes including having crisis support available 24 h per day, having a choice of different treatment modalities, being offered help for substance use problems and having a focus on improving symptoms rather than functioning. Simulations predicted that 60% of the Patient segment thought patients would remain engaged with a Hospital service, while 69% of the Professional segment thought patients would be most likely to remain engaged with an E-Health service. CONCLUSIONS: Patients, family members and professionals shared a number of preferences about what service characteristics will optimize patient engagement in early intervention services but diverged on others. Providing effective crisis support as well as a range of treatment options should be prioritized in the future design of early intervention services.

The formation of abnormal associations in schizophrenia: neural and behavioral evidence.

It is hypothesized that due to an abnormal functioning of the reward system patients with schizophrenia form context-inappropriate associations. It has been shown that the dopamine target regions, especially the ventral striatum, are critical in the formation of reward associations. We wanted to examine how the ventral striatum responds as patients learn reward-related associations and how this neural response is linked to objective and subjective behavioral measures. Functional magnetic resonance imaging (fMRI) Blood oxygen level dependent (BOLD) responses were examined using aversive Pavlovian learning in 13 medicated patients with schizophrenia and 13 matched healthy controls. Colored circles served as conditioned stimulus (CS+) while a loud, individually adjusted, noise served as the unconditioned stimulus. Circles of another color served as neutral comparators (CS-). Subjective indices were assessed by a post-scan self-report, and galvanic skin responses (GSR) were used as objective measures of associative learning. fMRI data were analyzed using a random effects model in SPM2. Patients showed inappropriately strong activations in the ventral striatum in response to the neutral stimulus (CS-) as compared to the healthy controls. Consistent with this neural evidence of aberrant learning, patients also showed evidence of abnormal learning by self-report and as indexed by GSR. The main finding here is that patients with schizophrenia, when exposed to neutral stimuli in a threatening situation, show an abnormal pattern of learning. The aberrant activations and response are consistent with the idea that patients aberrantly assign motivational salience to neutral stimuli, and this process may be one of the aberrations that predisposes them to psychosis.

Neuropsychological course in the prodrome and first episode of psychosis: findings from the PRIME North America Double Blind Treatment Study.

OBJECTIVE: There is uncertainty regarding the onset timing of the cognitive deficiencies of schizophrenia. We investigated whether conversion to psychosis and/or olanzapine altered the neuropsychological course of subjects within the first-ever double blind medication study of the putative schizophrenia first episode prodrome. METHOD: Sixty participants in a double blind trial of olanzapine as a treatment for putative prodromal states were assessed at entry (pre-randomization), and again at 6 and 12 months (if they remained non-psychotic), or at any of these points prior to psychosis followed by post-psychosis and 6 months post-psychosis assessments. RESULTS: Participants who converted to psychosis did not differ from placebo non-converters in pre-randomization global neuropsychological status. Early converters did not differ from later converters in entry neuropsychological status. Subjects who converted after 6 months did not show neuropsychological declines during the initial, pre-psychosis, 6 months. Neuropsychological course did not differ between converters to psychosis and non-converters, or between olanzapine and placebo-assigned subjects. CONCLUSIONS: Neither the onset of frank psychosis nor olanzapine treatment of the prodrome significantly alters neuropsychological course in persons considered to be at high risk at their initial (pre-psychosis) assessment. These findings suggest that the neuropsychological deficiencies associated with psychotic conditions largely pre-exist the first frank psychotic episode.

Cerebral white matter deficiencies in pedophilic men.

The present investigation sought to identify which brain regions distinguish pedophilic from nonpedophilic men, using unbiased, automated analyses of the whole brain. T1-weighted magnetic resonance images (MRIs) were acquired from men who demonstrated illegal or clinically significant sexual behaviors or interests (n = 65) and from men who had histories of nonsexual offenses but no sexual offenses (n = 62). Sexual interest in children was assessed by participants' admissions of pedophilic interest, histories of committing sexual offenses against children, and psychophysiological responses in the laboratory to erotic stimuli depicting children or adults. Automated parcellation of the MRIs revealed significant negative associations between pedophilia and white matter volumes of the temporal and parietal lobes bilaterally. Voxel-based morphometry corroborated the associations and indicated that the regions of lower white matter volumes followed, and were limited to, two major fiber bundles: the superior fronto-occipital fasciculus and the right arcuate fasciculus. No significant differences were found in grey matter or in cerebrospinal fluid (CSF). Because the superior fronto-occipital and arcuate fasciculi connect the cortical regions that respond to sexual cues, these results suggest (1) that those cortical regions operate as a network for recognizing sexually relevant stimuli and (2) that pedophilia results from a partial disconnection within that network.

Illness intrusiveness and subjective well-being in schizophrenia.

This study evaluated the extent to which schizophrenia and its treatment interferes with participation in valued life activities and its impact on subjective well-being. The Illness Intrusiveness Ratings Scale was completed by 78 individuals with schizophrenia on 3 measurement occasions. Clinicians working with participants, plus a relative/friend of each participant also provided independent ratings of the person. The Illness Intrusiveness Ratings Scale displayed internal consistency (coefficient alpha = 0.82), and temporal stability across 1 day (r = 0.89), 1 week (r = 0.51), and 1 month (r = 0.78). Reported intrusiveness was high (M = 50.5) and was among the highest compared with populations with other serious medical and psychiatric illnesses. Ratings correlated with staff and family/friends' ratings of intrusiveness (r = 0.33 and r = 0.40), measures of symptomatology (average r = 0.25), and subjective well-being (average r = 0.41). Path analysis indicated that lifestyle disruption mediates the impact of symptoms and treatment on well-being. Implications for these findings and future directions for research are discussed.

Adverse subjective experience with antipsychotics and its relationship to striatal and extrastriatal D2 receptors: a PET study in schizophrenia.

OBJECTIVES: Antipsychotic medications improve psychosis but often induce a state of dysphoria in patients. Blockade of the dopamine D(2) receptors, which is thought to mediate their efficacy, has also been implicated in producing this adverse subjective experience. The authors present the first double-blind controlled study to examine the relationship between striatal and extrastriatal dopamine D(2) receptor binding potential and occupancy values and adverse subjective experience. METHOD: Patients with recent-onset psychosis (N=12) were randomly assigned to low or high doses of olanzapine or risperidone. Subjective experiences, motor side effects, and striatal and extrastriatal dopamine D(2) receptors (determined with [(11)C]raclopride and [(11)C]FLB 457 PET scans, respectively) were evaluated after 2 weeks of continuous antipsychotic treatment. RESULTS: Higher dopamine D(2) receptor occupancy and binding potentials in the striatal (dorsal and ventral), temporal, and insular regions were associated with subjective experience. The finding was confirmed with two convergent methods of analysis (region-of-interest and voxel-based statistics), and the same relationship was observed using two different dopamine receptor measures (observed binding potential values and age- and sex-corrected occupancy values). CONCLUSIONS: Higher D(2) receptor occupancy is associated with negative subjective experience in patients taking risperidone or olanzapine. These negative subjective effects may be related to the high discontinuation rates seen in usual practice. Understanding the neurobiological mechanism of these negative subjective experiences and developing antipsychotics with novel (i.e., non D(2)) mechanisms may be critical in improving the treatment of psychosis.

Striatal vs extrastriatal dopamine D2 receptors in antipsychotic response--a double-blind PET study in schizophrenia.

Blockade of dopamine D2 receptors remains a common feature of all antipsychotics. It has been hypothesized that the extrastriatal (cortical, thalamic) dopamine D2 receptors may be more critical to antipsychotic response than the striatal dopamine D2 receptors. This is the first double-blind controlled study to examine the relationship between striatal and extrastriatal D2 occupancy and clinical effects. Fourteen patients with recent onset psychosis were assigned to low or high doses of risperidone (1 mg vs 4 mg/day) or olanzapine (2.5 mg vs 15 mg/day) in order to achieve a broad range of D2 occupancy levels across subjects. Clinical response, side effects, striatal ([11C]-raclopride-positron emission tomography (PET)), and extrastriatal ([11C]-FLB 457-PET) D2 receptors were evaluated after treatment. The measured D2 occupancies ranged from 50 to 92% in striatal and 4 to 95% in the different extrastriatal (frontal, temporal, thalamic) regions. Striatal and extrastriatal occupancies were correlated with dose, drug plasma levels, and with each other. Striatal D2 occupancy predicted response in positive psychotic symptoms (r=0.62, p=0.01), but not for negative symptoms (r=0.2, p=0.5). Extrastriatal D2 occupancy did not predict response in positive or negative symptoms. The two subjects who experienced motor side effects had the highest striatal occupancies in the cohort. Striatal D2 blockade predicted antipsychotic response better than frontal, temporal, and thalamic occupancy. These results, when combined with the preclinical data implicating the mesolimbic striatum in antipsychotic response, suggest that dopamine D2 blockade within specific regions of the striatum may be most critical for ameliorating psychosis in schizophrenia.

Inconsistency in the relationship between duration of untreated psychosis (DUP) and negative symptoms: sorting out the problem of heterogeneity.

BACKGROUND: Several studies have found an association between duration of untreated psychosis (DUP) and clinical outcomes. However, there is inconsistency concerning the association between outcome on negative symptoms and DUP with some studies having found a correlation between DUP and negative symptoms, while other studies did not find such an association. OBJECTIVE: The aim of the present study was to investigate the role of heterogeneity associated with the relationship between DUP and negative symptoms in a sample of first episode psychosis (FEP) patients from a multicentre treatment study and a replication sample of subjects from a specialized service in a different jurisdiction. METHOD: FEP patients (n=116) treated in specialized programs in two medium sized and one large urban centre were evaluated. Latent class regression was employed to simultaneously classify respondents and estimate the effect of DUP on negative symptoms after one year. The process was repeated on 59 consecutive FEP patients in a specialized service in Montreal. RESULTS: The final model reflected three distinct sub-groups with different associations between DUP and negative symptoms: (a) for one fourth of the subjects there was a positive association between DUP and negative symptoms, indicating that long DUP was associated with poor negative symptoms outcome; (b) an opposite effect was observed for another sub-group of patients: patients with short DUP scored high on the negative symptoms scale and patients with long DUP reported only a few negative symptoms; (c) there was no association between DUP and negative symptoms outcome for nearly half of the patients. These models were replicated in the Montreal sample. CONCLUSIONS: The association between DUP and negative symptoms outcome might differ among sub-groups of first episode patients. Latent class regression analysis offers a flexible way to include unmeasured heterogeneity in outcome analyses.

Substance use and abuse in first-episode psychosis: prevalence before and after early intervention.

UNLABELLED: Despite the high prevalence of substance abuse among first-episode psychosis (FEP) populations, few studies examine whether early intervention (EI) improves substance abuse. OBJECTIVE: To examine the prevalence and pattern of substance use and abuse among an FEP sample over 12 months. METHODS: All the participants were diagnosed with a first episode of a schizophrenia spectrum disorder. The participants were followed prospectively. The prevalence rates of substance use and abuse from this sample were compared before and after 12 months of EI services and were compared with rates observed in a sample from the general population. RESULTS: A total of 200 participants (80.0% males; mean age 24 years) entered the study: 183 participants completed all the assessments at baseline, 131 participants completed all the assessments at 12 months. At baseline, the findings showed similar prevalence rates between the FEP sample and the general sample for lifetime cannabis use (60% vs 55%, respectively) and hazardous alcohol use (26% vs 21%) but significantly different prevalence rates for lifetime hallucinogen (29% vs 15%; P < .001) and cocaine use (20% vs 14%; P < .001). At 12 months, the prevalence rates for drug abuse (P < .01), hazardous alcohol use (P < .01), and concurrent drug abuse and hazardous alcohol use (P < .05) were significantly lower than at baseline. CONCLUSION: Substance use and abuse decreased significantly after 12 months of EI services; EI services may be able to detect and to reduce substance use among FEP patients before it becomes a more serious disorder.

Characterizing outcome preferences in patients with psychotic disorders: a discrete choice conjoint experiment.

The majority of individuals with schizophrenia will achieve a remission of psychotic symptoms, but few will meet criteria for recovery. Little is known about what outcomes are important to patients. We carried out a discrete choice experiment to characterize the outcome preferences of patients with psychotic disorders. Participants (N=300) were recruited from two clinics specializing in psychotic disorders. Twelve outcomes were each defined at three levels and incorporated into a computerized survey with 15 choice tasks. Utility values and importance scores were calculated for each outcome level. Latent class analysis was carried out to determine whether participants were distributed into segments with different preferences. Multinomial logistic regression was used to identify predictors of segment membership. Latent class analysis revealed three segments of respondents. The first segment (48%), which we labeled "Achievement-focused," preferred to have a full-time job, to live independently, to be in a long-term relationship, and to have no psychotic symptoms. The second segment (29%), labeled "Stability-focused," preferred to not have a job, to live independently, and to have some ongoing psychotic symptoms. The third segment (23%), labeled "Health-focused," preferred to not have a job, to live in supervised housing, and to have no psychotic symptoms. Segment membership was predicted by education, socioeconomic status, psychotic symptom severity, and work status. This study has revealed that patients with psychotic disorders are distributed between segments with different outcome preferences. New approaches to improve outcomes for patients with psychotic disorders should be informed by a greater understanding of patient preferences and priorities.
