Mental health of Royal Canadian Mounted Police after the first year of service
Royal Canadian Mounted Police (RCMP) frequently report symptoms consistent with positive screens for one or more mental health disorders (65%), but RCMP cadets evidence a much lower prevalence (7.3%) prior to deployment. The differences in mental health between cadets and experienced RCMP implicates mental health challenges to be related to service experiences; however, less is known about how mental health changes during the first year of servic…
Characterizing heterogeneity in health-related quality of life trajectories in coronary artery disease
Internal validation methods to detect patient characteristics associated with differential item functioning in patient-reported outcome measures
Synthetic health data in Canada
SD have mainly been used in single-province studies and national surveys. Broader use in clinical and public HD with methodological consistency could strengthen its role for privacy-protecting, multi-jurisdictional research and surveillance initiatives
Can Patient-Reported Outcome Measures (PROMs) Help Predict Unplanned Hospital Readmission
BACKGROUND: Administrative data used to predict unplanned hospital readmissions often lack patient-reported symptoms and functional status. Integrating patient-reported outcome measures (PROMs) may improve risk prediction. OBJECTIVES: To assess the incremental value of PROMs in predicting unplanned readmissions to inform postdischarge monitoring and ongoing care management. METHODS: This population-based retrospective cohort study used linked adm…

Trouble with the curve
The creation of highly individualized, population-based mental health injury programs has been limited by an incomplete understanding of the causal relationships between protective factors and mental health. Disproportionate rates of disengagement from persons who screen positive for mental health disorders further compounds the difficulty in understanding the relationships between training programs and mental health. The current results suggest …
Covid-19 and pregnancy
This study provides valuable insights into the impact of pregnancy and pre-existing comorbidities on COVID-19 outcomes in WRA. The findings underscore the importance of considering demographic factors and pre-existing comorbidities in the management of PW with COVID-19. The study also highlights the need for further research to understand the unique impacts of different comorbidities, particularly immunosuppression and renal disease, on COVID-19 …

Unsupervised item response theory models for assessing sample heterogeneity in patient-reported outcomes measures
PCTree and MixPCM were not consistent in detecting covariates associated with differential interpretations of PROM items. Future research will use computer simulations to assess these models' Type I error and statistical power for identifying covariates associated with DIF
Assessing the impact of the Royal Canadian Mounted Police (RCMP) protocol and Emotional Resilience Skills Training (ERST) among diverse public safety personnel
ClinicalTrials.gov, NCT05530642. Registered 1 September 2022-Retrospectively registered. The subsequent PSP PTSI Study results are expected to benefit the mental health of all participants and, ultimately, all PSP
Transitions between versions of the International Classification of Diseases and chronic disease prevalence estimates from administrative health data
The prevalence of most of the investigated chronic health conditions changed significantly in the transition from ICDA-8 to ICD-9-CM. These results point to the importance of considering changes in ICD coding as a factor that may influence the interpretation of trend estimates for chronic health conditions derived from administrative health data
Control charts for chronic disease surveillance
Our study using control charts to compare stability of trends in incidence and prevalence for juvenile diabetes algorithms found no differences for disease incidence. Differences were observed between select algorithms for disease prevalence when using wider control limits

Response shift in results of patient-reported outcome measures
Future response shift research will benefit from collaboration among diverse people, formulating alternative hypotheses of response shift, and conducting the most conclusive studies aimed at testing these (falsification)
Measurement invariance of the Seattle Angina Questionnaire in coronary artery disease
Critical examination of current response shift methods and proposal for advancing new methods
No single response shift method is optimal; each method has strengths and limitations. Additionally, extra steps need to be taken to correctly interpret the results. Advancing new methods and conducting computer simulation studies that compare methods are recommended to move response shift research forward
Linking a History of Childhood Abuse to Adult Health among Canadians
A history of childhood abuse has been linked to serious and long-lasting problems in adulthood. We developed two theoretical models concerning how early adverse experiences affect health in adulthood, and we tested the empirical fit of the two models in a population-based representative sample of Canadian adults (N = 25,113) using a structural equation modelling (SEM) technique, path analysis. The first model included direct pathways by which a h…

Health and social predictors of applications to public housing
BACKGROUND: Residents of public housing are often in poor health. However, it is unclear whether poor health precedes residency in public housing. We compared the health of people who applied to public housing to people who did not apply and had similar socioeconomic characteristics. METHODS: Population-based administrative databases from Manitoba, Canada, containing health, housing and income assistance information were used to identify a cohort…
An evaluation of a person-centred care programme for long-term care facilities
Person-centred approaches in long-term care focus on providing holistic care to residents in order to improve quality of life, enhance resident wellbeing and autonomy, and mitigate behavioural and/or other symptoms. The results of research on person-centred approaches to care are mixed, with very few high-quality empirical studies examining resident outcomes specifically. The purpose of this investigation was to examine a person-centred care prog…

A framework for modelling differences in regional mortality over time
Study objective: To present a conceptual framework for testing differences in mortality for small geographical areas over time using the generalised linear model with generalised estimating equations. This framework can be used to test whether the magnitude of regional inequalities in health status has changed over time. Design: A Poisson regression model for correlated data is used to investigate the relation of population health status to demog…
A life history intervention for individuals with dementia
Behaviours of concern ( e.g. aggression) are often present in residents of long-term care (LTC) facilities diagnosed with dementia and may impact quality of life. Prior uncontrolled research has shown that an intervention involving sharing resident life histories may be effective in reducing aggressive behaviours and improving quality of life, perhaps by increasing staff empathy. We used a randomised controlled design, involving a considerably la…

Statistical Practices of Educational Researchers
Articles published in several prominent educational journals were examined to investigate the use of data analysis tools by researchers in four research paradigms: between-subjects univariate designs, between-subjects multivariate designs, repeated measures designs, and covariance designs. In addition to examining specific details pertaining to the research design (e.g., sample size, group size equality/inequality) and methods employed for data a…
To Trim or Not to Trim
Tests of mean equality proposed by Alexander and Govern, Box, Brown and Forsythe, James, and Welch, as well as the analysis of variance F test, were compared for their ability to limit the number of Type I errors and to detect true treatment group differences in one-way, completely randomized designs in which the underlying distributions were nonnormal, variances were nonhomogeneous, and groups sizes were unequal. These tests were compared when t…
Analyzing Multivariate Repeated Measures Designs
The approximate degrees of freedom Welch-James (WJ) and Brown-Forsythe (BF) procedures for testing within-subjects effects in multivariate groups by trials repeated measures designs were investigated under departures from covariance homogeneity and normality. Empirical Type I error and power rates were obtained for least-squares estimators and robust estimators based on trimming/Winsorization. The BF and WJ procedures with least-squares estimator…

Comparing Treatment and Control Groups on Multiple Outcomes
This study considers the problem of testing the difference between treatment and control groups on m ≥ 2 measures when it is assumed a priori that the treatment group will perform better than the control group on all measures. Two procedures are investigated that do not rest on the assumptions of covariance homogeneity or multivariate normality: a likelihood ratio test based on a bootstrap critical value and a composite step-down procedure based …

Socioeconomic variations in the prevalence and incidence of Parkinson's disease
BACKGROUND: For many chronic conditions, lower socioeconomic status is associated with higher rates of disease. Previous research has not investigated whether this inverse relationship exists for Parkinson's disease (PD). The purpose was to investigate the association between socioeconomic status and prevalence and incidence of PD. METHODS: The study was conducted using population-based administrative data from Manitoba, Canada. PD cases were ide…

Predictors of Severity and Duration of Infectious Disease Outbreaks in Long-Term Care Facilities in the Saskatoon Health Region
Introduction Infectious disease outbreaks in long-term care facilities (LTCFs) pose a significant threat to the health and well-being of residents. While prevention of all outbreaks is not realistic, minimising the severity and duration of outbreaks can be achieved through the prompt implementation of infection control policies, outbreak reporting to Public Health, and outbreak management. In this study, we investigated variables associated with …
Agreement Between Clinical and Administrative Health Databases for Medication Use in Saskatchewan's Long-Term Care Residents
Introduction The Resident Assessment Instrument Minimum Data Set (RAI-MDS) is a clinical tool intended to provide comparable and consistent information about the functional status and care needs of residents of long-term facilities (LTCFs). The RAI-MDS has been used in numerous studies about quality of care, including studies about the use of medications associated with potentially adverse health outcomes. However, the accuracy of many of the RAI…
