Early Psychosis Intervention and Primary Care: A Mixed Methods Study of Family Physician Knowledge, Attitudes, Preferences, and Needs.

Family physicians (FPs) play an important but underappreciated role in the pathways to care for people with early psychosis. We conducted a mixed-methods study to describe the knowledge, attitudes, preferences, and needs of FPs towards the recognition and management of early psychosis. We sent a cross-sectional postal survey to a random sample of FPs in Ontario, Canada, and conducted in-depth qualitative interviews with twenty.

Impact of non-medical cannabis legalization with market restrictions on health service use and incident cases of psychotic disorder in Ontario, Canada.

Background: Cannabis is a risk factor in the onset and persistence of psychotic disorders. There is concern that non-medical cannabis legalization in Canada may have population-level impacts on psychotic disorders. We sought to examine changes in health service use and incident cases of psychotic disorder following cannabis legalization, during a period of tight restrictions on retail stores and product types.

Access to a regular primary care physician among young people with early psychosis in Ontario, Canada.

Aim: Access to a primary care physician in early psychosis facilitates help-seeking and engagement with psychiatric treatment. We examined access to a regular primary care physician in people with early psychosis, compared to the general population, and explored factors associated with access.

Methods: Using linked health administrative data from Ontario (Canada), we identified people aged 14-35 years with a first diagnosis of nonaffective psychotic disorder (n = 39 449; 2005-2015).

The effect of non-medical cannabis retailer proximity on use of mental health services for psychotic disorders in Ontario, Canada.

Background: Cannabis is associated with the onset and persistence of psychotic disorders. Evidence suggests that accessibility of substances is associated with an increased risk of use-related harms. We sought to examine the effect of residing in proximity to non-medical cannabis retailers on the prevalence of health service use for psychosis.

Sex differences in the clinical presentation of early psychosis in a primary care setting.

Primary care is an important part of the help-seeking pathway for young people experiencing early psychosis, but sex differences in clinical presentation in these settings are unexplored. We aimed to identify sex differences in clinical presentation to primary care services in the 1-year period prior to a first diagnosis of psychotic disorder. We identified first-onset cases of non-affective psychotic disorder over a 10-year period (2005-2015) using health administrative data linked with electronic medical records (EMRs) from primary care (n = 465).

Patient and Physician Factors Associated with First Diagnosis of Non-affective Psychotic Disorder in Primary Care.

Primary care physicians play a central role in pathways to care for first-episode psychosis, and their increased involvement in early detection could improve service-related outcomes. The aim of this study was to estimate the proportion of psychosis first diagnosed in primary care, and identify associated patient and physician factors. We used linked health administrative data to construct a retrospective cohort of people aged 14-35 years with a first diagnosis of non-affective psychosis in Ontario, Canada between 2005-2015.

Sex and gender differences in symptoms of early psychosis: a systematic review and meta-analysis.

First-episode psychosis (FEP) can be quite variable in clinical presentation, and both sex and gender may account for some of this variability. Prior literature on sex or gender differences in symptoms of psychosis have been inconclusive, and a comprehensive summary of evidence on the early course of illness is lacking. The objective of this study was to conduct a systematic review and meta-analysis of the literature to summarize prior evidence on the sex and gender differences in the symptoms of early psychosis.

Gaming My Way to Recovery: A Systematic Scoping Review of Digital Game Interventions for Young People's Mental Health Treatment and Promotion.

Nearly all young people use the internet daily. Many youth with mental health concerns, especially since the Covid-19 pandemic, are using this route to seek help, whether through digital mental health treatment, illness prevention tools, or supports for mental wellbeing. Videogames also have wide appeal among young people, including those who receive mental health services.

Insights About Cannabis and Psychosis Using Video Games for Young People With a First Episode of Psychosis, Particularly Those From Black Racialized Communities: Protocol for a Mixed Methods Study.

Background: Cannabis use disorder among young people with a first episode of psychosis contributes to relapse, hospitalization, and impaired functioning. However, few studies have examined what young people with early phase psychosis, particularly those from Black racialized communities, understand or appreciate about this relationship, even though they may be at risk. There are no formally tested knowledge translation strategies that disseminate these research findings for young people with emerging psychosis from Black racialized communities.

Online Knowledge Translation Program Involving Video Games and University Student-Led Tutorials About Cannabis and Psychosis for Black Youth: Mixed Method Feasibility Study.

Background: We have piloted a new online knowledge translation (KT) program created to educate youth about cannabis effects, which uniquely focuses on mental health risks for Black youth. Youth are generally unaware of the research linking underage usage and the risk of psychosis. Youth from some Black racialized communities in Ontario may be disproportionately affected and in need of this knowledge.

Digital Game Interventions for Youth Mental Health Services (Gaming My Way to Recovery): Protocol for a Scoping Review.

Background: Digital or video games are played by millions of adolescents and young adults around the world and are one of the technologies used by youths to access mental health services. Youths with mental health problems strongly endorse the use of technologies, including mobile and online platforms, to receive information, support their treatment journeys (eg, decision-making tools), and facilitate recovery. A growing body of literature explores the advantages of playing digital games for improving attention span and memory, managing emotions, promoting behavior change, and supporting treatment for mental illness (eg, anxiety, depression, or posttraumatic stress disorder).

Feasibility and acceptability of a volunteer peer fidelity assessment model in early psychosis intervention programmes in Ontario: Results from a pilot study.

Aim: Fidelity monitoring can support high-quality service delivery but is resource-intensive to implement. A fidelity assessment model utilizing volunteer assessors was trialled as a low-cost strategy for conducting fidelity assessments. This article reports on the acceptability and feasibility of this model.

Using Fidelity Measurement to Assess Quality of Early Psychosis Intervention Services in Ontario.

Objectives: The First Episode Psychosis Services Fidelity Scale (FEPS-FS) is a validated measure of program delivery in relation to international standards. This study assessed fidelity in Ontario programs and the utility of the FEPS-FS for program improvement.

Methods: Assessments were conducted in a volunteer sample of nine early psychosis intervention (EPI) programs.

Understanding the role of the family physician in early psychosis intervention.

Background: The family physician is key to facilitating access to psychiatric treatment for young people with first-episode psychosis, and this involvement can reduce aversive events in pathways to care. Those who seek help from primary care tend to have longer intervals to psychiatric care, and some people receive ongoing psychiatric treatment from the family physician.

Aims: Our objective is to understand the role of the family physician in help-seeking, recognition and ongoing management of first-episode psychosis.

Youth Mental Health, Family Practice, and Knowledge Translation Video Games about Psychosis: Family Physicians' Perspectives.

Objective: Family practitioners face many challenges providing mental healthcare to youth. Digital technology may offer solutions, but the products often need to be adapted for primary care. This study reports on family physicians' perspectives on the relevance and feasibility of a digital knowledge translation (KT) tool, a set of video games, designed to raise awareness about psychosis, marijuana use, and facilitate access to mental health services among youth.

Gender differences in pathways to care for early psychosis.

Aims: Gender is a critical demographic determinant in first-episode psychosis research. We used data from the ACE Pathways to Care Project, which examined pathways to care in African-origin, Caribbean-origin and European-origin participants, to investigate the role of gender in pathways to early intervention programmes.

Method: A qualitative approach was used to examine gender differences in the routes to care.

Comparative analysis of pathways to early intervention services and duration of untreated psychosis in two Canadian cities.

Aim: Understanding pathways to early intervention services for psychosis in the local context is crucial, as the structure and organization of services need to be considered. This study compared pathways to early intervention services in two Canadian cities.

Methods: Data on pathways to care and duration of untreated psychosis were collected from 171 people admitted to early intervention services in Toronto (n = 150) and Hamilton (n = 21).

Symptom profiles and explanatory models of first-episode psychosis in African-, Caribbean- and European-origin groups in Ontario.

Aim: To assess variability in symptom presentation and explanatory models of psychosis for people from different ethnic groups.

Methods: Clients with first-episode psychosis (n = 171) who identified as black African, black Caribbean or white European were recruited from early intervention programmes in Toronto and Hamilton. We compared results by ethnic group for symptom profiles and explanatory models of illness.

Pathways to First-Episode Care for Psychosis in African-, Caribbean-, and European-Origin Groups in Ontario.

Objective: To compare the pathways to care and duration of untreated psychosis (DUP) for people of Black-African, Black-Caribbean, or White-European origin with first-episode psychosis (FEP).

Methods: We recruited a sample of 171 patients with FEP of Black-African, Black-Caribbean, and White-European origin from hospital- and community-based early intervention services (EIS) in the cities of Toronto and Hamilton. We compared the 3 groups on DUP and key indicators of the pathway to care.

The African, Caribbean and European (ACE) Pathways to Care study: a qualitative exploration of similarities and differences between African-origin, Caribbean-origin and European-origin groups in pathways to care for psychosis.

Objectives: This paper reports on a qualitative exploration of the reasons for differences in pathways to care and duration of untreated psychosis (DUP) in the African, Caribbean and European (ACE) Pathways to Care study from the perspective of respondents to the study and their families.

Setting: Ontario, Canada.

Participants: Thirty-four participants in total.

First-episode affective psychosis and lipid monitoring: survival analysis of the first abnormal lipid test.

Aim: This study aimed to assess the probability of developing a lipid test abnormality over time, among first-time users of antipsychotic medications with affective psychosis.

Methods: Survival analysis was used to analyse data from an early intervention in psychosis programme for the first 53 consecutive and eligible cases of patients between the ages of 14 and 40 years who had a diagnosis of affective psychosis. Data on initiation of antipsychotic medications and lipid laboratory test results were abstracted from chart reviews.

Race, ethnicity, and the duration of untreated psychosis: a systematic review.

Purpose: An extended duration of untreated psychosis (DUP) is associated with poor outcome in first-episode psychosis (FEP). Some have suggested that minority ethnic groups have longer treatment delays, and this could lead to worse outcomes. We systematically reviewed the literature on racial and ethnic differences in DUP in patients with FEP.

The Canadian Objective Assessment of Life Skills (COALS): a new measure of functional competence in schizophrenia.

This study examined the reliability and validity of a new performance-based measure of functional competence for individuals with serious mental illness, the Canadian Objective Assessment of Life Skills (COALS). The COALS assesses both routinized procedural knowledge routines (PKR) and executive operations (EXO) in order to capture functional outcome variance. The COALS was administered to 101 outpatients with schizophrenia and schizoaffective disorder and 80 non-psychiatric controls.

Reflections of young people who have had a first episode of psychosis: what attracted them to use alcohol and illicit drugs?

Aim: To identify factors that contribute to the initiation of alcohol and street drug use from the perspective of people who were enrolled in early intervention programmes for a first episode of psychosis.

Method: Eight focus groups were conducted involving an average of four to six participants per group, with each group consisting of young people who met provincial inclusion criteria for early intervention programmes. Thematic analysis was used to systematically code transcripts from the focus groups for concepts, patterns and themes related to early use of illicit substances.
