Relations between bullying and distress among youth living in First Nations communities: Assessing direct and moderating effects of culture-related variables.

The well-being of Indigenous peoples continues to be affected by intergenerational effects of numerous harmful government policies, which are considered root causes for bullying and cyberbullying that exist in some communities. Despite ongoing stressors, Indigenous youth demonstrate resilience, which often appears grounded in connecting to their cultural identities and traditional practices. However, few studies have tested the direct and stress-buffering role of various aspects of culture in relation to well-being among First Nations youth. Analyses of the 2015-16 First Nations Regional Health Survey (RHS) revealed that bullying and cyberbullying were associated with increased psychological distress among youth aged 12-17 living in First Nations communities across Canada (N = 4,968; weighted = 47,918), and that these links were stronger for females. Feelings of community belonging were directly associated with lower distress and buffered the relationships between bullying/cyberbullying and distress. Among youth who experienced cyberbullying, those who participated in community cultural events at least sometimes reported lower distress compared to those who rarely or never participated. Those who disagreed that traditional cultural events were important reported the highest levels of distress, but perceived importance of such events failed to buffer the associations between bullying/cyberbullying and distress. These national data highlight the importance of certain culture-related variables as key factors associated with the well-being of youth living in First Nations communities across Canada.

Parent-Child Separations and Mental Health among First Nations and Métis Peoples in Canada: Links to Intergenerational Residential School Attendance.

First Nations children are over 17 times more likely to be removed from their families and placed in the child welfare system (CWS) than non-Indigenous children in Canada. The high rates of parent-child separation have been linked to discriminatory public services and the Indian Residential School (IRS) system, which instigated a multi-generational cycle of family disruption. However, limited empirical evidence exists linking the IRS to subsequent parent-child separations, the CWS, and mental health outcomes among First Nations, Inuit, and Métis populations in Canada. The current studies examine these relationships using a nationally representative sample of First Nations youth (ages 12-17 years) living in communities across Canada (Study 1), and among First Nations and Métis adults (ages 18+ years) in Canada (Study 2). Study 1 revealed that First Nations youth with a parent who attended IRS had increased odds of not living with either of their biological parents, and both IRS and not living with biological parents independently predicted greater psychological distress. Similarly, Study 2 revealed that First Nations and Métis adults with familial IRS history displayed greater odds of spending time in the CWS, and both IRS and CWS predicted elevated depressive symptoms. The increased distress and depressive symptoms associated with parent-child separations calls for First Nations-led interventions to address the inequities in the practices of removing Indigenous children and youth from their families.

Rejection sensitivity and multiple group memberships: The moderating role of an oxytocin receptor gene polymorphism.

Rejection sensitivity is a cognitive-affective processing disposition that has been linked to interpersonal difficulties. In this regard, the neuropeptide hormone, oxytocin, is thought to underlie social cognitions and behaviors that promote social affiliation. A single nucleotide polymorphism (SNP) on the oxytocin receptor gene (OXTR), in which guanine (G) is substituted for adenine (A), has been associated with less support-seeking behaviors. In the current study, among 376 undergraduate students, it was shown that the relationship between rejection sensitivity and depressive symptoms was mediated by multiple group memberships. Furthermore, the relation between rejection sensitivity and group memberships was only evident among individuals possessing the A allele on the OXTR gene. These findings further support the psychosocial deficits characteristic of individuals possessing the OXTR polymorphism, which in turn is linked to poor mood.

Intolerance of uncertainty, appraisals, coping, and anxiety: the case of the 2009 H1N1 pandemic.

OBJECTIVES: Although ambiguous and uncertain situations, such as those dealing with the threat of widespread viral illness, may have pronounced psychological ramifications, there have been few studies that examined the factors that contributed to such outcomes. The purpose of the present investigation was to examine emotional reactions to a health threat. DESIGN: A structural equation model examined the interplay between anxiety and intolerance of uncertainty, as sequentially mediated by appraisals and coping strategies. METHODS: Adult participants over the age of 18 (N = 1,027) completed online self-report measures during the H1N1 pandemic in 2009. RESULTS: Greater intolerance of uncertainty was related to lower appraisals of self- and other control, which predicted low levels of problem-focused coping and greater reports of H1N1-related anxiety. Additionally, individuals with a high intolerance of uncertainty were more likely to perceive the pandemic as threatening and also were more apt to use emotion-focused coping strategies, and both of these factors predicted elevated levels of anxiety. CONCLUSIONS: Together, these data indicate that threats, such as those related to a potential pandemic, not only have implications for physical health, but also for psychological distress, and that such outcomes vary with a constellation of appraisal and coping factors. STATEMENT OF CONTRIBUTION: What is already known on this subject? It has been established that the public is often confused by the threat that a potential pandemic virus poses and that they are unsure of what information related to the disease they can trust. Government health agencies often walk the line of minimizing the threat to prevent panic, but simultaneously emphasize the importance of action (vaccination) to prevent a worldwide pandemic. What does this study add? Beyond the physical threat of a pandemic, a significant psychological toll may occur for certain individuals. Anxiety regarding H1N1 is heightened amongst those who cannot tolerate uncertainty. Appraisals of threat, control, and the use of emotion-focused coping mediate the above relationship.

Cortisol rise following awakening among problem gamblers: dissociation from comorbid symptoms of depression and impulsivity.

Gambling pathology has been associated with elevated levels of distress, depression and impulsivity. The present investigation assessed whether these behavioral features would be evident among problem gamblers as they are among pathological gamblers. As well, given that gambling has been associated with increased life stress, as an objective index of ongoing distress, elevations of morning cortisol levels were assessed in problem and pathological gamblers relative to recreational gamblers, and their relations to depressive symptoms and impulsivity were assessed. Recreational, problem, and pathological gamblers (N = 140) completed the Beck Depression Inventory and the Barratt Impulsiveness Scale-11, and provided saliva samples at awakening, 30 min, 3.5 h, and 5.5 h afterward. Consistent with the view that problem and pathological gambling are associated with elevated life stressors, the rise of morning cortisol from awakening to 30 min following awakening was greater than in recreational gamblers. Heightened impulsivity was evident among both problem and pathological gamblers, whereas depressive symptoms were only evident among pathological gamblers. In neither instance were these psychological indices related to the morning cortisol rise. Indeed, increased depressive symptoms were not evident among problem gamblers, despite the fact that elevated morning cortisol levels were evident. The elevated morning cortisol rise may be secondary to gambling problems or distress related to gambling problems. Furthermore, the sustained morning cortisol elevations may be indicative of allostatic overload, and could potentially be a harbinger for potential health risks among problematic gamblers.

Risk factors for stress fracture among young female cross-country runners.

PURPOSE: To identify risk factors for stress fracture among young female distance runners. METHODS: Participants were 127 competitive female distance runners, aged 18-26, who provided at least some follow-up data in a randomized trial among 150 runners of the effects of oral contraceptives on bone health. After completing a baseline questionnaire and undergoing bone densitometry, they were followed an average of 1.85 yr. RESULTS: Eighteen participants had at least one stress fracture during follow-up. Baseline characteristics associated (P<0.10) in multivariate analysis with stress fracture occurrence were one or more previous stress fractures (rate ratio [RR] [95% confidence interval]=6.42 (1.80-22.87), lower whole-body bone mineral content (RR=2.70 [1.26-5.88] per 1-SD [293.2 g] decrease), younger chronologic age (RR=1.42 [1.05-1.92] per 1-yr decrease), lower dietary calcium intake (RR=1.11 [0.98-1.25] per 100-mg decrease), and younger age at menarche (RR=1.92 [1.15-3.23] per 1-yr decrease). Although not statistically significant, a history of irregular menstrual periods was also associated with increased risk (RR=3.41 [0.69-16.91]). Training-related factors did not affect risk. CONCLUSION: The results of this and other studies indicate that risk factors for stress fracture among young female runners include previous stress fractures, lower bone mass, and, although not statistically significant in this study, menstrual irregularity. More study is needed of the associations between stress fracture and age, calcium intake, and age at menarche. Given the importance of stress fractures to runners, identifying preventive measures is of high priority.

Ruminative coping among patients with dysthymia before and after pharmacotherapy.

The pivotal role of rumination in relation to other coping strategies was assessed in chronically depressed (dysthymic disorder) individuals versus nondepressed controls. Individuals with dysthymia demonstrated elevated use of rumination and other emotion-focused strategies (emotional expression, emotional containment, self- and other-blame). Among patients with dysthymia, rumination was linked to this limited array of emotion-focused efforts and diminished use of cognitive disengagement, whereas among controls, rumination was correlated with a broad constellation of problem- and emotion-focused strategies. Following 12 weeks of pharmacotherapy (sertraline), despite attenuation of depressed mood and reduced rumination, the limited relations between rumination and emotion-focused efforts persisted. Inflexibility in the ability to combine various coping efforts effectively may be characteristic of individuals with dysthymia, potentially increasing risk for recurrence.

Understanding sadomasochism: an empirical examination of four perspectives.

Three studies assessed current understandings of sadomasochism (SM). In Study 1 questionnaires testing four academic views of SM were administered to individuals who self-defined as involved in SM. The psychoanalytic, psychopathology/medical model, radical feminist and escape-from-self perspectives were not supported. Study 2 examined "virtual" sadomasochism as a source of information about sadomasochists in the real life world. Cluster analyses indicated that real-life and virtual sadomasochists share unique sexual proclivities. Study 3 examined an alternative view that identifies power as the commodity of importance in SM play. Content analysis of online SM encounters indicated that both "top" and "bottom" role-players used several specific techniques to create a power differential. These studies suggest that, contrary to many academic theories, power, and not the giving and receiving of pain, is at the core of SM.

Stress, depression, and anhedonia: caveats concerning animal models.

Numerous animal models of depression have been advanced, each having multiple attributes and some limitations. This review provides caveats concerning etiologically valid animal models of depression, focusing on characteristics of the depressive subtype being examined (e.g. typical vs atypical major depression, dysthymia, melancholia), and factors that contribute to the interindividual behavioral variability frequently evident in stressor-related behavioral paradigms. These include the stressor type (processive vs systemic stressors), and characteristics of the stressor (controllability, predictability, ambiguity, chronicity, intermittence), as well as organismic variables (genetic, age, sex), experiential variables (stressor history, early life events) and psychosocial and personality factors that moderate stressor reactivity. Finally, a model of depression is reviewed that evaluates the effects of stressors on hedonic processes, reflected by responding for rewarding brain stimulation. Anhedonia is a fundamental feature of depression, and assessment of stressor-related reductions in the rewarding value of brain stimulation, especially when coupled with other potential symptoms of depression, provides considerable face, construct and predictive validity. Stressful events markedly impact rewarding brain stimulation, and this effect varies across strains of mice differentially reactive to stressors, is modifiable by antidepressant treatments, and allows for analyses of the contribution of different brain regions to anhedonic processes. The paradigm is sensitive to several factors known to acts as moderators of stress responses, but analyses remain to be conducted with regard to several such variables.

What is the best topical anesthetic for nasogastric insertion? A comparison of lidocaine gel, lidocaine spray, and atomized cocaine.

INTRODUCTION: Nasogastric intubation has been shown to be a painful procedure for patients. Previous studies have demonstrated the benefit of topical nasal anesthesia in decreasing the pain of this procedure. This study attempts to identify which of 3 topical anesthetic modalities would be preferred by patients. METHODS: This study had a double-blind, double-dummy randomized triple crossover design with 30 healthy volunteers as participants. Each participant had 3 nasogastric tubes inserted and acted as his or her own control for the 3 study medications: 1.5 mL 4% atomized lidocaine, 1.5 mL 4% atomized cocaine, and 5 mL 2% lidocaine gel. Participants scored pain of tube passage through the nostril as well as global discomfort. They were also asked to identify which agent they preferred. RESULTS: In our 30 subjects, although no statistically significant difference in nasal pain scores was found, "global discomfort" was less with the lidocaine gel (P =.017). Participants preferred the lidocaine gel over atomized cocaine (P <.00), but not to a statistically significant degree. DISCUSSION: Two percent lidocaine gel appeared to provide the best option for a topical anesthetic during nasogastric tube insertion.
