Systematic comparison of duration of untreated illness versus duration of untreated psychosis in relation to psychopathology and dysfunction in the Cavan-Monaghan first episode psychosis study (CAMFEPS).

This study systematically compared duration of untreated illness (DUI) with duration of untreated psychosis (DUP) in prediction of impairment at first-episode psychosis and investigated the extent to which these relationships are influenced by premorbid features. The Cavan-Monaghan First Episode Psychosis Study ascertained cases of first-episode psychosis in rural Ireland via all routes to care with limited variations in socioeconomic milieu. Cases were evaluated for DUI and DUP and assessed clinically for psychopathology, neuropsychology, neurology, insight and quality of life, together with premorbid features.

Perspectives on paid work among men and women with schizophrenia: The results of a two study comparison in Ireland.

Background: While research indicates that people with serious mental health conditions want to work, few studies have examined motivation and concerns associated with employment.

Objectives: This study examined the work attitudes among two samples of Irish people with psychotic conditions, primarily schizophrenia.

Methods: Data gathered through two work related research projects was used.

Systematic epidemiological and clinical comparisons across all 12 DSM-IV psychotic diagnoses in the Cavan-Monaghan First Episode Psychosis Study (CAMFEPS).

Background: Research on psychotic illness is loosening emphasis on diagnostic stringency in favour of including a more dimensionally based conceptualization of psychopathology and pathobiology. However, to clarify these notions requires investigation of the full scope of psychotic diagnoses.

Methods: The Cavan-Monaghan First Episode Psychosis Study ascertained cases of first episode psychosis across all 12 DSM-IV psychotic diagnoses via all routes to care: public, private or forensic; home-based, outpatient or inpatient.

Disagreement between service-users and clinicians assessment of physical health during early psychosis.

Aims: Physical illnesses account for the majority of excess deaths following psychosis; access to care and treatment is inequitable and schizophrenia has now been dubbed the life-shortening disease. We compared service-users and clinician's perspectives of their physical health assuming that one of the fundamental issues in prompting screening and treatment is the view that health is poor.

Methods: Data comprising sample characteristics, diagnosis, symptoms, insight, antecedents to psychosis and physical health perspectives were obtained prospectively as part of a larger epidemiological study of first-episode psychosis.

Functional outcome and service engagement in major depressive disorder with psychotic features: comparisons with schizophrenia, schizoaffective disorder and bipolar disorder in a 6-year follow-up of the Cavan-Monaghan First Episode Psychosis Study (CAMFEPS).

Objective: While long-term outcome following a first psychotic episode is well studied in schizophrenia (SZ), schizoaffective disorder (SA), and bipolar disorder (BD), major depressive disorder with psychotic features (MDDP) has received less investigation. This study compares MDDP with SZ, SA, and BD at 6-year follow-up.

Methods: At 6 years after a first psychotic episode, follow-up data on psychopathology, functioning, quality of life, and service engagement were obtained for 27 cases of MDDP in comparison to 60 SZ, 27 SA, and 35 BD.

Predictors of change in social networks, support and satisfaction following a first episode psychosis: A cohort study.

Background: Diminished social networks are common in psychosis but few studies have measured these comprehensively and prospectively to determine how networks and support evolve during the early phase. There is little information regarding perceived support in the early phase of illness. The aim of this study was to describe social support, networks and perceived satisfaction, explore the clinical correlates of these outcomes and examine whether phases of untreated psychosis are linked with social network variables to determine potential opportunities for intervention.

An exploratory study of the extent of social inclusion among people with psychosis and psychotic-related conditions.

Background: Understanding social inclusion among at-risk populations will deepen our understanding of their specific needs.

Aim: This study explored the level of social inclusion among people with psychotic-related conditions using a standardised interview.

Method: The Social Inclusion Interview Schedule was used in two research projects.

Feasibility of a psychosis information intervention to improve mental health literacy for professional groups in contact with young people.

The aim of this study was to assess the feasibility of a psychosis information intervention for professionals in contact with young people in Ireland. A quasi-experimental pre- and post-intervention design was used. One thousand and thirty-two professionals received an information intervention designed to improve mental health literacy (MHL) and confidence in providing help to people with psychosis.

Contribution of copy number variants to schizophrenia from a genome-wide study of 41,321 subjects.

Copy number variants (CNVs) have been strongly implicated in the genetic etiology of schizophrenia (SCZ). However, genome-wide investigation of the contribution of CNV to risk has been hampered by limited sample sizes. We sought to address this obstacle by applying a centralized analysis pipeline to a SCZ cohort of 21,094 cases and 20,227 controls.

Socioeconomic status at birth and risk for first episode psychosis in rural Ireland: Eliminating the features of urbanicity in the Cavan-Monaghan First Episode Psychosis Study (CAMFEPS).

Background: There is a paucity of research on the relationship between social environment at birth and risk for psychosis in rural settings. This study examined the relationship between individual- and neighbourhood-level socioeconomic indicators proximal to the time of birth and risk for a first psychotic episode in a rural context using a prospective dataset of unusual epidemiological completeness.

Methods: A matched case-control design was used.

The relationship between mental health literacy regarding schizophrenia and psychiatric stigma in the Republic of Ireland.

Background: There is an unclear relationship between mental health literacy (MHL) and psychiatric stigma. MHL is associated with both positive and negative attitudes to mental illness. To our knowledge, no published peer reviewed study has examined this relationship in the Republic of Ireland.

Environmental factors and the age at onset in first episode psychosis.

Objective: Factors that influence the age at onset in psychotic disorders could provide valuable insights into precipitating or causative factors of the disorder. Despite being established risk factors, it is not yet known whether migration status, place of birth, social class at birth and season of birth influence the age at onset of psychotic disorders. This study aimed to determine whether these environmental factors, in addition to cannabis abuse and obstetric complications, influence the age at onset.

Prodromal symptoms and remission following first episode psychosis.

Introduction: Describing the trajectory of prodromal symptoms has obvious appeal in supporting advances towards sub-clinical intervention. Identifying clinical phenomena associated with unfavourable illness outcomes could have greater significance in explaining some heterogeneity within and between psychotic disorders and advancing understanding of pre-psychotic typologies. Few studies have assessed the continuity, if any, between prodromal phases and illness outcome one year after treatment.

Subjective and objective quality of life at first presentation with psychosis.

Aim: Quality of life (QOL) in first-episode psychosis (FEP) is impaired when compared to non-clinical controls and several clinical factors including symptoms and untreated psychosis have been linked with poorer QOL. Measurement methods are varied, however, resulting in inconsistent findings and there is a need to simultaneously combine subjective and objective measures of QOL.

Methods: We examined both subjective (n = 128) and objective QOL (n = 178) in a catchment area cohort of individuals with FEP (n = 222) to determine correspondence between patient satisfaction and clinician-rated functional domains.

Negative symptom domain prevalence across diagnostic boundaries: The relevance of diagnostic shifts.

Negative symptoms are included in diagnostic manuals as part of criteria for schizophrenia spectrum psychoses only, however some studies have found their presence in other diagnoses. This study sought to clarify negative symptom domain prevalence across diagnostic categories, while investigating whether negative symptoms predicted diagnostic shift over time. Scale for the Assessment of Negative Symptoms (SANS) data were collected at first presentation in 197 individuals presenting with first episode psychosis and again at one year follow-up assessment.

Social class at birth and risk of psychosis.

Background: Individuals with psychotic disorders are represented more in the lower social classes, yet there is conflicting evidence to whether these individuals drift into the lower social classes or whether lower social class is a risk factor for developing psychosis. The aim of this study was to examine whether the social class at birth is a risk factor for developing psychosis.

Methods: We included individuals with a first episode of psychosis (FEP) whose social class at birth was determined from birth records.

Improving social functioning and reducing social isolation and loneliness among people with enduring mental illness: Report of a randomised controlled trial of supported socialisation.

Background: This randomised controlled trial examined if for people with enduring mental illness, being supported to socialise leads to improved social functioning, increased self-esteem and extended social networks; a reduction in social isolation, social, emotional and family loneliness and a reduction in illness symptoms, namely depression.

Methods: A prospective randomised controlled trial was undertaken from November 2007 to September 2011. Service users with a diagnosis of enduring mental illness (>18 years) were invited to participate.

Work life after psychosis: A detailed examination.

Background: Conducting research on the work outcomes of first episode psychosis (FEP) samples may extend our understanding of the factors associated with the work outcome of people with schizophrenia and other psychotic illnesses.

Objective: To conduct a detailed study of the work outcome of an FEP sample.

Methods: Members of a FEP cohort, who had completed a 12-year clinical outcome assessment, were invited to participate in an adjunctive work outcome study.

Daily weather variables and affective disorder admissions to psychiatric hospitals.

Numerous studies have reported that admission rates in patients with affective disorders are subject to seasonal variation. Notwithstanding, there has been limited evaluation of the degree to which changeable daily meteorological patterns influence affective disorder admission rates. A handful of small studies have alluded to a potential link between psychiatric admission rates and meteorological variables such as environmental temperature (heat waves in particular), wind direction and sunshine.

An inherited duplication at the gene p21 Protein-Activated Kinase 7 (PAK7) is a risk factor for psychosis.

Identifying rare, highly penetrant risk mutations may be an important step in dissecting the molecular etiology of schizophrenia. We conducted a gene-based analysis of large (>100 kb), rare copy-number variants (CNVs) in the Wellcome Trust Case Control Consortium 2 (WTCCC2) schizophrenia sample of 1564 cases and 1748 controls all from Ireland, and further extended the analysis to include an additional 5196 UK controls. We found association with duplications at chr20p12.

Neighbourhood-level socio-environmental factors and incidence of first episode psychosis by place at onset in rural Ireland: the Cavan-Monaghan First Episode Psychosis Study [CAMFEPS].

Background: Little is known about associations between the social environment and risk for psychosis within rural settings. This study sought to investigate whether such associations exist within a rural context using a prospective dataset of unusual epidemiological completeness.

Method: Using the Cavan-Monaghan First Episode Psychosis Study database of people aged 16 years and older, both ecological analyses and multilevel modelling were applied to investigate associations between incidence of psychosis by place at onset and socio-environmental risk factors of material deprivation, social fragmentation and urban-rural classification across electoral divisions.

Scale for the Assessment of Negative Symptoms structure in first episode psychosis.

Previous studies in schizophrenia samples suggest negative symptoms can be categorized as expressivity or experiential. This study examines the structure of the Scale for the Assessment of Negative Symptoms (SANS) at two separate interviews in a first episode psychosis (FEP) sample. SANS structure was determined with principal components analysis in a schizophrenia spectrum (SSD, N=191) and non-schizophrenia spectrum (NSSD, N=246) sample at first presentation.

Comparison of generic and disease-specific measures of quality of life in first-episode psychosis.

Background: Quality of life (QOL) is now recognised as an important measure of outcome that could potentially influence clinical decision-making for those with a first-episode psychosis (FEP). A number of QOL instruments are available however; many differ in their conceptual orientation which may have serious implications for the outcome of QOL studies, interpretation of findings and clinical utility. We aimed to compare two commonly used tools representing both generic and disease-specific constructs to examine whether both tools appraise the same underlying QOL traits and also whether disease-specific tools retain their psychometric properties when used in FEP groups.

Detection and characteristics of individuals with a very long duration of untreated psychosis in an early intervention for psychosis service.

Aim: Early intervention (EI) services for psychosis aim to reduce the duration of untreated psychosis (DUP) with intensive large-scale multi-focus initiatives, including public awareness campaigns. As a consequence of this approach, individuals with a very long DUP who might have otherwise remained undiagnosed may come to medical attention. The aim of this study was to investigate if an EI service detected additional cases of individuals with a first-episode psychosis (FEP) with a very long DUP and identify demographic and clinical characteristics associated with a very long DUP.
