The purpose of this study was to train and test preliminary models using two machine learning algorithms to identify healthcare workers at risk of developing anxiety, depression, and post-traumatic stress disorder. The study included data from a prospective cohort study of 816 healthcare workers collected using a mobile application during the first...

Introduction Previous research has demonstrated the negative impact of the COVID-19 pandemic emergency on the wellbeing of healthcare workers. However, few research contributions reported a longitudinal evaluation of psychological distress and examined determinants of its duration and course over time. The present study aims to explore the impact o...

The provision of services that improve the functioning, social participation and quality of life of individuals with behavioral or mental health problems is a common denominator amongst psychosocial professionals in Quebec, including social workers, psychologists and psychoeducators. One intervention that has gained empirical support as an interven...

Les professionnels de l’intervention psychosociale au Québec, dont les travailleurs sociaux, les psychologues et les psychoéducateurs, ont comme dénominateur commun d’offrir des services visant à améliorer le fonctionnement, la participation sociale et la qualité de vie des individus aux prises avec des difficultés d’adaptation ou des problèmes de...
Article
Introduction: The COVID-19 pandemic had an impact on the psychological health of healthcare workers (HCWs). Cross-sectional studies report suicidal ideation in this population during this period, but no longitudinal study has examined the evolution of these ideas over time. Objectives: To assess the evolution of suicidal ideation of HCWs during the...
Article
Full-text available
Several studies have reported conflicting results when assessing associations between stress and repetitive behaviors in individuals with autism spectrum disorder (ASD). Some factors that may have caused these discrepant results include the monitoring of a single broad category for repetitive behaviors, the heterogeneity of the participants, and th...
Article
Full-text available
Background: Health care workers (HCW) exposed to COVID-19 risk experiencing psychological distress. Little is known regarding longitudinal perspectives and evolutions of psychological distress within this population. The objective of this study is to extend the results of our previous study to the pandemic's second wave. Method: This prospective...
Article
Objectives Health-care workers (HCW) exposed to COVID-19 are at risk of experiencing psychological distress. Although several cross-sectional studies have been carried out, a longitudinal perspective is needed to better understand the evolution of psychological distress indicators within this population. The objectives of this study were to assess...
Article
Full-text available
Both researchers and practitioners often rely on direct observation to measure and monitor behavior. When these behaviors are too complex or numerous to be measured in vivo, relying on direct observation using human observers increases the amount of resources required to conduct research and to monitor the effects of interventions in practice. To a...

Both researchers and practitioners often rely on direct observation to measure and monitor behavior. When these behaviors are too complex or numerous to be measured in vivo, relying on direct observations using human observers increases the costs of conducting research and monitoring interventions in practice. To address this issue, we conducted a...
Article
Many children with autism spectrum disorder (ASD) engage in challenging behaviors, which may interfere with their daily functioning, development, and well-being. To address this issue, we conducted a four-week randomized waitlist control trial to examine the effects of a fully self-guided interactive web training (IWT) on (a) child engagement in ch...
Article
Health professionals often recommend the use of medical devices to assess the health, monitor the well‐being, or improve the quality of life of their patients. Children with autism may present challenges in these situations as their sensory peculiarities may increase refusals to wear such devices. To address this issue, we systematically replicated...
Article
The purpose of our study was to compare the effectiveness of tablet- and instructor-delivered teaching (i.e., prompting and reinforcement) on the receptive identification of one-word concepts in children with autism spectrum disorders (ASDs). To this end, we embedded a multielement design within a multiple probe design to compare the effectiveness...
Chapter
Behavior analysts typically conceptualize social skills as behaviors, or series of behaviors, that mediate the responses of others. As such, practitioners may assess and teach social skills using the principles of learning derived from operant conditioning (e.g., positive reinforcement). In the current chapter, we first discuss the conceptualizatio...
Article
Given that children with autism spectrum disorders (ASDs) often require one-to-one individualized instruction, using tablets as teaching tools may represent an interesting option in classrooms with high student to teacher ratios. The purpose of our study was to extend research by evaluating the effects of tablet-based instruction on the generalizat...
Article
Purpose: The purpose of our study was to compare the effects of serial and concurrent training on the generalization of receptive identification in children with autism spectrum disorders (ASD). Methods: We taught one to three pairs of stimulus sets to nine children with ASD between the ages of three and six. One stimulus set within each pair wa...
Article
The purpose of our study was to examine the probability of observing false positives in nonsimulated data using the dual-criteria methods. We extracted data from published studies to produce a series of 16,927 datasets and then assessed the proportion of false positives for various phase lengths. Our results indicate that collecting at least three...
Article

To compare trends in coverage of empirically supported and alternative autism treatments in Canadian newspapers during a 10-year period and to examine whether the portrayal of empirically supported and alternative treatments differed. We searched a sample of 10 daily local and national Canadian newspapers using the word autism combined with interve...
