Transgender individuals face heightened risks for discrimination, harassment, and violence that impact their psychosocial well-being and physical health. However, few studies have thoroughly examined the general physical and mental health of transgender adults or within-group health differences by race/ethnicity and income. To that end, after controlling for health insurance status, age, and engagement in exercise, this study asks: (a) Are transgender people of color more likely than White transgender individuals to experience poor health outcomes? and (b) Is lower annual household income among transgender adults associated with poorer health outcomes? The study analyzes secondary data from a survey of transgender adults (N = 417) in one state in the western United States using multiple linear regression and logistic regression models. Results showed that transgender people of color had significantly greater odds than their White counterparts of having arthritis/rheumatoid arthritis/gout/lupus/fibromyalgia, or asthma but lower odds of being told by a provider that they had depression. Having a lower income was significantly associated with worse general health as well as multiple indicators of poor physical and mental health, including depression, anxiety, and suicidal ideation. We discuss implications for health care delivery for transgender people and for future research.  相似文献

In Memory: A Philosophical Study, Bernecker argues for an account of contiguity. This Contiguity View is meant to solve relearning and prompting, wayward causation problems plaguing the causal theory of memory. I argue that Bernecker’s Contiguity View fails in this task. Contiguity is too weak to prevent relearning and too strong to allow prompting. These failures illustrate a problem inherent in accounts of memory causation. Relearning and prompting are both causal relations, wayward only with respect to our interest in specifying remembering’s requirements. Solving them requires saying more about remembering, not causation. I conclude by sketching such an account.  相似文献

Objectives: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect.

Design: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects.

Main outcome measures: We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect.

Results: Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (rCorrect Recall = ?.273), were less able to differentiate between listed and unlisted side effects (rRecognition Sensitivity = ?.256) and were more likely to attribute the unlisted headache symptom as a side effect (rside effect attribution = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects.

Conclusion: Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.  相似文献

Parent–adolescent conflict poses risk for youth maladjustment. One potential mechanism of this risk is that stress in the form of increased arousal during conflict interactions results in adolescents’ impaired decision-making. However, eliciting consistent adolescent stress responses within laboratory-based tasks of parent–adolescent conflict (i.e., conflict discussion tasks) is hindered by task design. This limitation may stem from how conflict topics are assessed and selected for discussion. Within a sample of 47 adolescents (ages 14–17) and parents, we investigated whether a modified version of a conflict discussion task could elicit physiological (i.e., arousal) and behavioral (i.e., hostility) displays of adolescents’ conflict-related stress responses. We assessed parent–adolescent conflict via structured interview to identify topics for dyads to discuss during the task. We randomly assigned dyads to complete a 5-min task to discuss either a putatively benign topic (i.e., control condition) or a conflict topic while undergoing direct assessments of continuous arousal. Trained raters coded dyad members’ hostile behavior during the task. Adolescents in the conflict condition exhibited significantly greater levels of arousal than adolescents in the control condition. We observed an interaction between discussion condition and baseline conflict. Specifically, higher baseline conflict predicted greater hostile behavior for adolescents in the conflict condition, yet we observed the inverse relation for adolescents in the control condition. Our modified laboratory discussion task successfully elicited both physiological and behavioral displays of adolescent conflict-related stress. These findings have important implications for leveraging experimental paradigms to understand causal links between parent–adolescent conflict and adolescent psychopathology, and their underlying mechanisms.  相似文献

Although a group of people working together recalls more items than any one individual, they recall fewer unique items than the same number of people working apart whose responses are combined. This is known as collaborative inhibition, and it is a robust effect that occurs for both younger and older adults. However, almost all previous studies documenting collaborative inhibition have used stimuli that were neutral in emotional valence, low in arousal, and studied by all group members. In the current experiments, we tested the impact of picture-stimuli valence, picture-stimuli arousal, and information distribution in modulating the magnitude of collaborative inhibition. We included both younger and older adults because there are age differences in how people remember emotional pictures that could modulate any effects of emotion on collaborative inhibition. Results revealed that when information was shared (i.e., studied by all group members), there were robust collaborative inhibition effects for both neutral and emotional stimuli for both younger and older adults. However, when information was unshared (i.e., studied by only a single group member), these effects were attenuated. Together, these results provide mixed support for the retrieval strategy disruption account of collaborative inhibition. Supporting the retrieval strategy disruption account, unshared study information was less susceptible to collaborative inhibition than shared study information. Contradicting the retrieval strategy disruption account, emotional valence and arousal did not modulate the magnitude of collaborative inhibition despite the fact that participants clustered the emotional, but not neutral, information together in memory.  相似文献

Using the Deese-Roediger-McDermott-Read-Solso (DRMRS) procedure in which list items are shown that are semantically related to a central theme that is not presented, undergraduates (N?=?61) studied either short or long lists in the form of auditory words alone, pictures alone, or pictures accompanied by auditory words. Correct recall and correct recognition scores were similar in all three conditions. However, false memory (reporting the non-presented central theme) was reduced with pictures alone compared to words alone for the recall task, and for the recognition task with short lists. Confidence was higher for correct recall and correct recognition than for false recall and false recognition, but people who were higher or lower in confidence did not differ on any memory measure. Theoretical and practical implications of these results are discussed.  相似文献

Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants but sacrifice control over sound presentation and therefore are not widely employed in hearing research. To help standardize online sound presentation, we introduce a brief psychophysical test for determining whether online experiment participants are wearing headphones. Listeners judge which of three pure tones is quietest, with one of the tones presented 180° out of phase across the stereo channels. This task is intended to be easy over headphones but difficult over loudspeakers due to phase-cancellation. We validated the test in the lab by testing listeners known to be wearing headphones or listening over loudspeakers. The screening test was effective and efficient, discriminating between the two modes of listening with a small number of trials. When run online, a bimodal distribution of scores was obtained, suggesting that some participants performed the task over loudspeakers despite instructions to use headphones. The ability to detect and screen out these participants mitigates concerns over sound quality for online experiments, a first step toward opening auditory perceptual research to the possibilities afforded by crowdsourcing.  相似文献

Emotional avoidance—which includes cognitive and attentional processes that function as means of avoiding or dampening emotional experiences—may be a transdiagnostic risk and maintenance factor for emotional disorders. However, existing measures generally assess separate aspects of emotional avoidance, and few multidimensional measures exist for adolescents. The aim of the current study was to establish the psychometric properties of a new multidimensional measure of emotional avoidance for adolescents--the Emotional Avoidance Strategy Inventory for Adolescents (EASI-A; Fairholme et al. 2008)--employing an exploratory structural equation modeling framework. Analyses yielded a three-factor structure for the EASI-A, including subscales measuring Avoidance of Emotion Expression, Avoidance of Thoughts and Feelings, and Distraction. Moderate correlations were observed between the EASI-A and a measure of thought suppression, and the EASI-A was significantly associated with anxiety and depression symptoms. The EASI-A is a new, psychometrically sound measure that will aid in the assessment of avoidance as a vulnerability factor for psychopathology and as an outcome and mechanism for treatments of emotional disorders in adolescents.  相似文献

Purpose

The present study examined the moderating effects of family-supportive supervisor behaviors (FSSB) on the relationship between two types of workplace aggression (i.e., patient-initiated physical aggression and coworker-initiated psychological aggression) and employee well-being and work outcomes.

Methodology

Data were obtained from a field sample of 417 healthcare workers in two psychiatric hospitals. Hypotheses were tested using moderated multiple regression analyses.

Findings

Psychiatric care providers’ perceptions of FSSB moderated the relationship between patient-initiated physical aggression and physical symptoms, exhaustion and cynicism. In addition, FSSB moderated the relationship between coworker-initiated psychological aggression and physical symptoms and turnover intentions.

Implications

Based on our findings, family-supportive supervision is a plausible boundary condition for the relationship between workplace aggression and well-being and work outcomes. This study suggests that, in addition to directly addressing aggression prevention and reduction, family-supportive supervision is a trainable resource that healthcare organizations should facilitate to improve employee work and well-being in settings with high workplace aggression.

Originality

This is the first study to examine the role of FSSB in influencing the relationship between two forms of workplace aggression: patient-initiated physical and coworker-initiated psychological aggression and employee outcomes.
