Item Properties and the Validity of Personality Assessment
The aim of the current research was to evaluate psychometric properties of personality questionnaire items that can affect their validity, as measured by comparing self-ratings with roommate ratings on a series of personality questionnaires. The item properties under investigation included item content saturation, item social desirability, and mean item responses. Archival data collected between 1981 and 2004 representing various groups of same-sex undergraduate roommate dyads were used for the purpose of this research. Results demonstrated that item content saturation was the most consistent predictor of item response accuracy. Mean item responses also predicted accurate responding curvilinearly, with moderate mean item responses eliciting the most accuracy. In order to better predict outcome variables in education, clinical, and vocational contexts using scores on personality questionnaires, it is important for researchers to employ item selection procedures that take into account the specific item properties that we know can affect personality test validity
The Role of Dark Personalities in Intimate Partner Violence
Intimate partner violence (IPV) is an international public health concern that poses significant mental and physical health risks for affected individuals. To improve prevention and intervention efforts, it is imperative that researchers and government bodies understand risk factors for IPV. This dissertation sought to evaluate individual differences in personality and childhood experiences as risk factors for various forms of IPV. The first two studies in this dissertation assessed whether the Dark Tetrad personality traits moderated the relationships between participants’ and their partners’ levels of IPV perpetration. In these studies, we assessed whether the Dark Tetrad traits operated differently in their associations with bidirectional IPV (i.e., both partners perpetrating violence against each other). The first sample comprised 109 men and 290 women (age range = 17-33, Mage = 18.74, SDage = 1.84) recruited through the psychology participant pool at the University of Western Ontario. Results showed that the relationships between participants’ and their partners’ frequency of IPV varied depending on their levels of specific Dark Tetrad traits. Participants in Study 2 were 153 men and 207 women recruited from Amazon’s Mechanical Turk (age range = 18-73, Mage = 34.39, SDage = 10.96). Results showed that being female, higher levels of partner IPV perpetration severity, and Factor 2 psychopathy resulted in significantly higher odds of engaging in more severe IPV perpetration. Finally, the third study investigated whether the Dark Tetrad traits mediated the relationships between exposure to violence in childhood and subsequent IPV perpetration in adulthood. A total of 153 men and 246 women (age range = 18-73, Mage = 33.50, SDage = 10.26) were recruited through Amazon’s Mechanical Turk. Results showed no relationship between IPV perpetration and childhood IPV exposure. Therefore, mediation analyses were not possible. Follow-up exploratory analyses demonstrated that gender moderated the relationships between childhood IPV exposure and levels of Factor 1 psychopathy and Machiavellianism. Results from this research have implications for future implementation of appropriate interventions in the context of IPV perpetration. It is also important to implement better education on individual differences as mechanisms underlying IPV perpetration for society as a whole

Feeling safe at work:Development and validation of the Psychological Safety Inventory
Psychological safety, defined as perceptions that an individual within a team is supported and feels safe to take interpersonal risks, voice opinions, and share ideas, is vital for organizational effectiveness. However, there is no consensus on how workplace psychological safety should be measured. We developed the Psychological Safety Inventory (PSI) in response to organizational needs to accurately assess psychological safety. A 70-item version of the PSI was administered to 497 employees from Canada, the United States, and the United Kingdom. Based on factor analytic findings, we reduced the preliminary PSI to a 30-item, five-factor scale. The PSI showed high reliability and correlated as anticipated with convergent measures. Overall, the PSI is a valid and reliable measure of workplace psychological safety.</p
An Investigation of the Psychometric Properties of the Chinese Trait Emotional Intelligence Questionnaire Short Form (Chinese TEIQue-SF)
The present study examined the psychometric properties of the Chinese version of the Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF). Analyses were performed using a sample of undergraduates (N = 585) recruited from four universities across China. Confirmatory factor analysis of the Chinese TEIQue-SF supported the one-factor structure of trait emotional intelligence. Measurement invariance analyses were conducted across the Chinese sample and a sample of Canadian undergraduate students (N = 638). Although the two samples demonstrated configural and partial metric invariance, scalar invariance was not found. Cross-cultural implications and explanations of the present findings, as well as suggestions for future research are discussed
Impact of the COVID-19 pandemic on the mental health and well-being of Veterans’ spouses: a cross sectional analysis
Background COVID-19 has negatively impacted the mental health and well-being of both Canadians and the world as a whole, with Veterans, in particular, showing increased rates of depression, anxiety, and PTSD. Spouses and common-law partners often serve as primary caregivers and sources of support for Veterans, which may have a deleterious effect on mental health and increase risk of burnout. Pandemic related stressors may increase burden and further exacerbate distress; yet the effect of the pandemic on the mental health and well-being of Veterans’ spouses is currently unknown. This study explores the self-reported mental health and well-being of a group of spouses of Canadian Armed Forces Veterans and their adoption of new ways to access healthcare remotely (telehealth), using baseline data from an ongoing longitudinal survey. Methods Between July 2020 and February 2021, 365 spouses of Veterans completed an online survey regarding their general mental health, lifestyle changes, and experiences relating to the COVID-19 pandemic. Also completed were questions relating to their use of and satisfaction with health-care treatment services during the pandemic. Results Reported rates of probable major depressive disorder (MDD), generalized anxiety disorder (GAD), alcohol use disorder (AUD), and PTSD were higher than the general public, with 50–61% believing their symptoms either directly related to or were made worse by the pandemic. Those reporting being exposed to COVID-19 were found to have significantly higher absolute scores on mental health measures than those reporting no exposure. Over 56% reported using telehealth during the pandemic, with over 70% stating they would continue its use post-pandemic. Conclusions This is the first Canadian study to examine the impact of the COVID-19 pandemic specifically on the mental health and well-being of Veterans’ spouses. Subjectively, the pandemic negatively affected the mental health of this group, however, the pre-pandemic rate for mental health issues in this population is unknown. These results have important implications pertaining to future avenues of research and clinical/programme development postpandemic, particularly relating to the potential need for increased support for spouses of Veterans, both as individuals and in their role as supports for Veterans
The mediating roles of workplace support and ethical work environment in associations between leadership and moral distress: a longitudinal study of Canadian health care workers during the COVID-19 pandemic
IntroductionThe COVID-19 pandemic has resulted in heightened moral distress among health care workers (HCWs) worldwide. Past research has shown that effective leadership may mitigate potential for the development of moral distress. However, no research to date has considered the mechanisms by which leadership might have an influence on moral distress. We sought to evaluate longitudinally whether Canadian HCWs’ perceptions of workplace support and ethical work environment would mediate associations between leadership and moral distress.MethodsA total of 239 French- and English-speaking Canadian HCWs employed during the COVID-19 pandemic were recruited to participate in a longitudinal online survey. Participants completed measures of organizational and supervisory leadership at baseline and follow-up assessments of workplace support, perceptions of an ethical work environment, and moral distress.ResultsAssociations between both organizational and supervisory leadership and moral distress were fully mediated by workplace supports and perceptions of an ethical work environment.DiscussionTo ensure HCW well-being and quality of care, it is important to ensure that HCWs are provided with adequate workplace supports, including manageable work hours, social support, and recognition for efforts, as well as an ethical workplace environment
Defining and Assessing the Syndrome of Moral Injury:Initial Findings of the Moral Injury Outcome Scale Consortium
Potentially morally injurious events (PMIEs) entail acts of commission (e.g., cruelty, proscribed or prescribed violence) or omission (e.g., high stakes failure to protect others) and bearing witness (e.g., to grave inhumanity, to the gruesome aftermath of violence), or being the victim of others' acts of commission (e.g., high stakes trust violations) or omission (e.g., being the victim of grave individual or systemic failures to protect) that transgress deeply held beliefs and expectations about right and wrong. Although there is a proliferation of interest in moral injury (the outcome associated with exposure to PMIEs), there has been no operational definition of the putative syndrome and no standard assessment scheme or measure, which has hampered research and care in this area. We describe an international effort to define the syndrome of moral injury and develop and validate the Moral Injury Outcome Scale (MIOS) in three stages. To ensure content validity, in Stage I, we conducted interviews with service members, Veterans, and clinicians/Chaplains in each country, inquiring about the lasting impact of PMIEs. Qualitative analysis yielded six operational definitions of domains of impact of PMIEs and components within domains that establish the parameters of the moral injury syndrome. From the domain definitions, we derived an initial pool of scale items. Stage II entailed scale refinement using factor analytic methods, cross-national invariance testing, and internal consistency reliability analyses of an initial 34-item MIOS. A 14-item MIOS was invariant and reliable across countries and had two factors: Shame-Related (SR) and Trust-Violation-Related (TVR) Outcomes. In Stage III, MIOS total and subscale scores had strong convergent validity, and PMIE-endorsers had substantially higher MIOS scores vs. non-endorsers. We discuss and contextualize the results and describe research that is needed to substantiate these inaugural findings to further explore the validity of the MIOS and moral injury, in particular to examine discriminant and incremental validity.</p
