Sex differences in mental disorder symptoms among Canadian police officers: the mediating role of social support, stress, and sleep quality.

Police officers, and specifically women officers, report elevated mental disorder rates relative to the general population, which may be impacted by sleep quality, policing-related stress, and social support. In a sample of Canadian police officers, sex was indirectly related to post traumatic stress, depression, generalized anxiety, panic, and social anxiety symptoms through its relationships with social support and sleep quality, but not through policing-related stress. Sex was indirectly related to problematic alcohol use symptoms through sleep quality only. Differences in clinical symptom severity between both sexes may be partially accounted for by the worsened sleep quality reported by women officers relative to their men counterparts. Conversely, general social support appears to be a protective, albeit insufficient, factor influencing the mental health of women police officers. Male and women police officers did not differ in their reports of policing-related stress. The current results underscore the importance of incorporating strategies to improve sleep practices into police workplace environments. Additionally, findings that general social support and policing-related stress do not help explain the trend of increased clinical severity reported by women police suggest that more research is still needed to identify and delineate other contributing factors.

Demographic and cognitive risk factors for police mental disorder symptoms.

The current study was designed to assess whether cognitive risk factors (i.e. anxiety sensitivity (AS), intolerance of uncertainty (IU)) explained variance in mental disorder symptoms in Canadian police officers beyond variance explained by demographic variables (i.e. sex, marital status, education, years of service). Police participants (708 men; 271 women) completed measures assessing posttraumatic stress disorder, panic disorder, social anxiety disorder, major depressive disorder, generalized anxiety disorder, IU and AS. Multivariate analysis of variance demonstrated that only main effects of sex were significant for all symptom variables, except SAD. Hierarchical multiple regressions demonstrated that AS and IU accounted for greater variance than sex on all mental disorder symptom measures, which suggests that cognitive risk factors explain more variance in mental disorder symptoms than sex. Efforts to reduce AS and IU may be beneficial for improving police mental health.

Factor Structure and Measurement Invariance of the Alcohol Use Disorders Identification Test (AUDIT) in a Sample of Military Veterans with and without PTSD.

Background: The Alcohol Use Disorders Identification Test (AUDIT) was developed as a screening tool for problematic alcohol use and an intervention framework to aid those who drink excessively. While the AUDIT is widely used with at-risk populations, such as military veterans, major gaps exist in the research literature regarding the construct validity of the AUDIT in military samples. Objectives: This study assessed the factor structure and measurement invariance of the AUDIT in a large sample of Canadian military veterans (N = 1669; 94.94% male). Methods: Exploratory factor analysis (EFA) was conducted using a random subsample (n = 825) to assess the underlying factor structure of the AUDIT. Confirmatory factor analysis (CFA), using the second subsample (n = 844), was used to cross-validate the factor structure revealed by EFA and compare it to other model variants. Finally, multigroup CFAs were conducted using the whole sample to further cross-validate the factor structure and examine measurement invariance in military veterans with and without clinical elevations in posttraumatic stress disorder (PTSD) symptoms. Results: Factor analyses revealed that a modified two-factor model provided a statistically better fit to the data compared to all other model variants; yet, the results did not confirm measurement invariance across military veterans with and without clinically significant symptoms of PTSD. Conclusions/Importance: The findings are in line with increasing evidence suggesting that two subscale scores should be calculated for the AUDIT. Results further suggest that care should be taken in interpreting AUDIT scores when PTSD symptoms are present for military veterans.

Attentional bias and its temporal dynamics among war veterans suffering from chronic pain: Investigating the contribution of post-traumatic stress symptoms.

BACKGROUND: Cognitive models propose that attentional dysregulation, including an attentional bias towards threat, is one of the factors through which chronic pain and post-traumatic stress symptoms (PTSS) maintain and exacerbate one another. The current investigation assessed the attentional bias for painful facial expressions and its relationship with PTSS, using both traditional and variability-based attentional bias measures, among veterans with chronic pain and PTSS and controls. METHOD: Fifty-four veterans with chronic pain and 30 age/education-matched controls participated in this investigation. Participants completed a self-report measure of PTSS and a modified version of the dot-probe task with painful, happy, and neutral facial expressions. Attention was assessed using both traditional and variability-based reaction time measures of attentional bias. RESULTS: Veterans directed attention away from painful facial expressions (i.e., avoidance) relative to both the control group (between-subject effect) and relative to neutral faces (within-subject effect). Veterans also showed significantly elevated attentional bias variability for both happy and painful facial expressions compared to controls. Attentional bias variability for happy and painful facial expressions was correlated with PTSS among all participants. CONCLUSION: Veterans with chronic pain and PTSS avoided pain-related stimuli and displayed an overall attentional dysregulation for emotional facial expressions. Avoidance of pain cues may be a coping strategy that these individuals develop under stressful conditions. Implications, limitations, and directions for future research are discussed.
