Abstract: Physical inactivity is a key contributor to the global burden of disease and disproportionately impacts the wellbeing of people experiencing mental illness. Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness. The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Patients with a DSM or ICD mental illness diagnoses were recruited and completed the SIMPAQ on two occasions, one week apart. Participants wore an Actigraph accelerometer and completed brief cognitive and clinical assessments. Evidence of SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1010 participants. The SIMPAQ had good test-retest reliability. Correlations for moderate-vigorous physical activity was comparable to studies conducted in general population s les. Evidence of validity for the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had stronger evidence of validity. This alternative method is recommended for use in future studies employing the SIMPAQ. The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.

Abstract: Recent studies have shown that outcome in mania is worse than previously thought. Such studies have been conducted in selected s les with restrictive measures of outcome. We aimed to explore outcome and its predictors in a catchment area s le of first-episode psychotic mania of DSM-III-R bipolar I disorder. Prospective 6 and 12 months follow-up was conducted with 87 DSM-III-R first-episode psychotic mania patients admitted to Early Psychosis Prevention and Intervention Centre between 1989 and 1997. Syndromic and symptomatic outcome were determined with the Brief Psychiatric Rating Scale functional outcome with the Quality of Life Scale and Premorbid Adjustment Scale subitems. Symptomatic outcome was assessed in 67 patients at 6 months and 61 patients at 12 months, and functional outcome in 56 patients at 6 months and 49 patients at 12 months. Logistic regressions were conducted on 46 and 43 patients, respectively, to explore predictors of outcome. While 90% of patients achieved syndromic recovery at 6 and 12 months, 40% had not recovered symptomatically at 6 and 12 months, still presenting with anxiety or depression. A total of 66% of patients at 6 months and 61% of patients at 12 months failed to return to previous level of functioning. Age at intake, family history of affective disorder, illicit drug use and functional recovery at 6 months predicted functional outcome at 12 months. This study confirms poor symptomatic and functional outcome after first-episode psychotic mania. It suggests possible usefulness of early intervention strategies in bipolar disorders and need for developing specific interventions addressing anxiety, depression and substance abuse comorbidity.

Abstract: The validity of schizoaffective disorder (SA) diagnosis has for long been a matter of controversy and its delineation from bipolar I disorders (BD) has often been questioned. However, most studies have been conducted in chronic s les and have therefore been biased towards patients with poorer outcome, which may have h ered the possibility to identify significant differences between both diagnoses. 108 subjects presenting a first DSM-III-R manic episode with psychotic features were assessed at baseline and 12 months after stabilisation on symptoms and functional characteristics, and patients with BD (n=87) were compared with those with SA bipolar subtype (SAB) (n=21). SAB patients had a higher prevalence of first degree relatives with schizophrenia and a lower premorbid functional level. They had a longer prodromal phase, a longer duration of untreated psychosis and remained symptomatic for a longer period. They also had higher levels of positive symptoms in the acute manic phase however, with two exceptions, the type of psychotic symptoms were similar in both groups. At stabilisation and 12 months after stabilisation, SA patients had higher levels of negative symptoms, with poorer functional level at 12 months. These data suggest SA is a valid diagnosis in the early phase of psychotic disorders considering it defines a subgroup of first episode psychotic mania patients with distinct characteristics compared to BD. While a dimensional approach to diagnosis may be more adapted to this phase of illness, SA disorder offers, in the context of categorical classifications, a useful intermediate category that reflects a clinical reality.

Abstract: Over the past decade, both clinical and research interest in the early stages of psychotic disorders has grown. This has been associated with research suggesting that early intervention in these disorders may limit their impact on the life of the affected in idual and his or her family. It has also been recognized that the biological and psychological changes underpinning the development of psychotic disorders may already be active in the prepsychotic or prodromal phase. It has been suggested that efforts to prevent psychotic disorders should be focused on this phase of emerging illness. In this article, the authors review work conducted at the PACE Clinic in Melbourne, Australia since 1994. This clinical research program was established to develop strategies for identifying young people at high risk for developing a psychotic disorder within a short period. The program has also investigated biological and psychological processes thought to underlie the development of psychosis and evaluated potential preventive interventions.

Abstract: Over the last 30 years, early intervention services (EIS) for first-episode psychosis (FEP) were gradually implemented in the province of Quebec. Such implementation occurred without provincial standards/guidelines and policy commitment to EIS until 2017. Although the literature highlights essential elements for EIS, studies conducted elsewhere reveal that important EIS components are often missing. No thorough review of Quebec EIS practices has ever been conducted, a gap we sought to address. Adopting a cross-sectional descriptive study design, an online survey was distributed to 18 EIS that existed in Quebec in 2016 to collect data on clinical, administrative, training, and research variables. Survey responses were compared with existing EIS service delivery recommendations. Half of Quebec’s population had access to EIS, with some regions having no programs. Most programs adhered to essential components of EIS. However, ergence from expert recommendations occurred with respect to variables such as open referral processes and patient–clinician ratio. Nonurban EIS encountered additional challenges related to their geography and lower population densities, which impacted their team size/composition and intensity of follow-up. Most Quebec EIS offer adequate services but lack resources and organizational support to adhere to some core components. Recently, the provincial government has created EIS guidelines, invested in the development of new programs and offered implementation support from the National Centre of Excellence in Mental Health. These changes, along with continued mentoring and networking of clinicians and researchers, can help all Quebec EIS to attain and maintain recommended quality standards.

Abstract: To explore the impacts of the COVID‐19 pandemic first wave in Quebec, Canada on practices in early intervention services (EIS) for first‐episode psychosis, including reorganization of clinical and administrative practices and teleconsultation use. Adopting a cross‐sectional descriptive study design, a 41 questions online survey was sent to the team leaders of all the 33 Quebec EIS, of which 100% responded. Data were collected from 18 May to 4 June 2020 and analysed using descriptive statistics and content analysis. Programmes were categorized as urban/non‐urban and results were compared between these. All 33 existing Quebec EIS (16 urban and 17 non‐urban) completed the survey. Among them, 85% did not experience redeployment of EIS team staff and 58% reported stable frequency of patient interactions, either in‐person or through telemedicine. During the studied period, 64% of programmes reported that all professionals used teleconsultation at least occasionally. However, 73% of programmes, mostly in non‐urban areas, reported some limitations regarding clinicians' degree of ease with teleconferencing platforms and half of EIS could not access technical support to use them. The majority of EIS (94%) expressed interest to participate in a training program about the use of technologies for teleconsultations. Many smaller clinics reported interest in offering multiregional/multiclinics group teletherapy, therefore merging their pool of patients and clinical staff workforce. Further studies are warranted to improve access to and use of technology‐mediated treatment, which seems to be a promising alternative to provide high‐quality mental healthcare during the COVID‐19 pandemic and beyond.

Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness. Methods: The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Investigators from 43 centres in 23 countries collected reliability and validity data on the SIMPAQ from patients with DSM or ICD mental illness diagnoses. Test-retest repeatability was assessed one-week apart. Results: Criterion SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1,010 participants. The SIMPAQ had good test-retest reliability (Spearman rho approximately 0.70). Criterion validity for moderate-vigorous physical activity was comparable to studies conducted in general population s les. Criterion validity of the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had greater criterion validity. This alternative method is recommended for use in future studies employing the SIMPAQ. Conclusions: The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.

Abstract: Early intervention services for psychosis (EIS) are associated with improved clinical and economic outcomes. In Quebec, clinicians led the development of EIS from the late 1980s until 2017 when the provincial government announced EIS-specific funding, implementation support and provincial standards. This provides an interesting context to understand the impacts of policy commitments on EIS. Our primary objective was to describe the implementation of EIS three years after this increased political involvement. This cross-sectional descriptive study was conducted in 2020 through a 161-question online survey, modeled after our team's earlier surveys, on the following themes: program characteristics, accessibility, program operations, clinical services, training/supervision, and quality assurance. Descriptive statistics were performed. When relevant, we compared data on programs founded before and after 2017. Twenty-eight of 33 existing EIS completed the survey. Between 2016 and 2020, the proportion of Quebec's population having access to EIS rose from 46% to 88% ,300 yearly admissions were reported by surveyed EIS, surpassing governments’ epidemiological estimates. Most programs set accessibility targets adopted inclusive intake criteria and an open referral policy engaged in education of referral sources. A wide range of biopsychosocial interventions and assertive outreach were offered by interdisciplinary teams. Administrative/organisational components were less widely implemented, such as clinical/administrative data collection, respecting recommended patient-to-case manager ratios and quality assurance. Increased governmental implementation support including dedicated funding led to widespread implementation of good-quality, accessible EIS. Though some differences were found between programs founded before and after 2017, there was no overall discernible impact of year of implementation. Persisting challenges to collecting data may impede monitoring, data-informed decision-making, and quality improvement. Maintaining fidelity and meeting provincial standards may prove challenging as programs mature and adapt to their catchment area's specificities and as caseloads increase. Governmental incidence estimates may need recalculation considering recent epidemiological data.
