Attention-Deficit/Hyperactivity Disorder (ADHD) is highly comorbid with other childhood disorders, and there are striking sex differences in this comorbidity, particularly during early childhood. For example, boys with ADHD are more likely to exhibit comorbid disruptive behavior and neurodevelopmental disorders, compared to girls, during early childhood. Yet, explanations for these well-established sex differences remain in short supply. The current study evaluated the novel hypothesis that personality traits may serve as intermediate phenotypes that help explain sex differences in common ADHD comorbidity profiles during early childhood. Study participants were 109 children between the ages of 3 and 6 and their primary caregivers and teachers/daycare providers, recruited from the community and over-recruited for ADHD-related problems. Primary caregivers completed the Child Behavior Checklist, and teachers/daycare providers completed the Teacher Report Form as a measure of child behavior problems. Examiners completed the California Q-Sort as a measure of child personality traits. Moderated mediation analyses suggested that personality traits explain associations between ADHD and oppositional-defiance, aggression, and language problems in a sex-specific manner. While high neuroticism mediated associations between ADHD and oppositional-defiance in girls, disagreeableness mediated associations between ADHD and aggression and low conscientiousness mediated associations between ADHD and neurodevelopmental language problems in boys. Sex differences in trait-psychopathology associations may help explain sex differences in comorbidity profiles with possible implications for child assessment and personalized early intervention.  相似文献

People from diverse backgrounds enrich the rural, regional, and remote communities where they relocate and settle. Research about rural diversity tends to focus on demographics (age, gender, country of origin) while ignoring personal narratives of integration, for example, engagements with religious institutions (such as the local Christian church). This article presents the research themes from an investigation using co-operative inquiry into rural diversity and the Anglican Church, with specific reference to the Australian experience. It is a cross-disciplinary dialogic exchange between social workers and theologians. Positive narratives about connection, welcome, participation, and belonging are shared.  相似文献

The purpose of this research was to examine the lived experience of a family unit that lost their spouse/mother/sister-in-law to cancer. A phenomenological case study was used to guide this research. Four participants, or one family unit consisting of one spouse, one daughter, one son, and one sister-in-law to the deceased, were recruited from Southern Ontario. Background questionnaires and one-on-one semi-structured interviews were conducted with each family member. The following themes emerged: (1) Negatives and (2) Silver Linings. This paper only addresses the theme “Silver Linings”; the first theme was addressed in Part I of this research. Within the theme “Silver Linings,” there were two sub-themes: (1) “…She was remarkable” and (2) Hope for the future. Each will be discussed in turn. Overall, the research study revealed some silver linings that may come from a diagnosis of cancer in a family unit. The family found it difficult to find positives in the loss of their loved one; however, they were able to acknowledge that they have a heightened appreciation for others. This research study provides insight regarding the lived experiences of families coping with the cancer journey of a loved one. It may allow readers to develop a greater sense of appreciation for their health and family members.  相似文献

Previously called Secondary Traumatic Stress (STS), secondary exposure to trauma is now considered a valid DSM-5 Criterion A stressor for posttraumatic stress disorder (PTSD). Previous studies have found high rates of STS in clinicians who treat traumatically injured patients. However, little research has examined STS among Emergency Medicine (EM) physicians and advanced practice providers (APPs). The current study enrolled EM providers (N = 118) working in one of 10 hospitals to examine risk factors, protective factors, and the prevalence of STS in this understudied population. Most of the participants were physicians (72.9%), Caucasian (85.6%), and male (70.3%) with mean age of 39.7 (SD = 8.9). Overall, 12.7% of the sample screened positive for STS with clinical levels of intrusion, arousal, and avoidance symptom clusters, and 33.9% had at least one symptom cluster at clinical levels. Low resilience and a history of personal trauma were positively associated with positive STS screens and STS severity scores. Borderline significance suggested that female gender and spending ≥10% of one’s time with trauma patients could be additional risk factors. Findings suggest that resilience-building interventions may be beneficial.  相似文献

This study examines the impact of the “Great Recession” (from December 2007 to June 2009) on 8th and 10th graders in the USA, using annual nationally representative data from the Monitoring the Future study. Historical changes in youth adjustment (self‐esteem, depressed mood, risk taking, aggression and property crime), school achievement (grade point average [GPA], time spent on homework and educational expectations) and structured and unstructured activities (volunteering, employment, sports and evenings out for fun) were examined between 1991 and 2014. Overall, there were only slight changes in mean levels of adjustment, achievement and most youth activities. However, the percentage of youth working during the school year did decline during the Great Recession. Several longer‐term trends were also evident, though not directly tied to the Great Recession. These include an increase in GPA, a decrease in time spent on homework, rising educational expectations and more time spent volunteering. Future work should assess how the shift to unpaid work activities (e.g. volunteering and internships) among youth is impacting the transition from school to work in the contemporary economy, and whether the Great Recession had deleterious impacts for younger children or among youth whose parents lost work or had their homes foreclosed.  相似文献

Autism spectrum disorder (ASD) and typically developed (TD) adult participants viewed pairs of scenes for a simple "spot the difference" (STD) and a complex "which one's weird" (WOW) task. There were no group differences in the STD task. In the WOW task, the ASD group took longer to respond manually and to begin fixating the target "weird" region. Additionally, as indexed by the first-fixation duration into the target region, the ASD group failed to "pick up" immediately on what was "weird". The findings are discussed with reference to the complex information processing theory of ASD (Minshew & Goldstein, 1998 ).  相似文献

Through his development of Rational Emotive Behaviour Therapy (REBT), Albert Ellis was a major contributor to the development of cognitive behaviour therapy. This article reviews key aspects of REBT, the distinction between unhealthy and healthy emotions, and the role irrational and rational beliefs play in relation to these emotions. As with other areas of psychology, the focus of REBT over the years has been dominated by negative emotional experiences. In an attempt to address this and further develop REBT, the present article reviews recent claims from the realm of social psychology that positive illusions promote mental health. Consequently, it is proposed that a similar dichotomy of healthy and unhealthy positive emotions also exists, and a basic framework for working with this positive dichotomy is introduced.  相似文献

A major ethical concern in research with criminal offenders is the potential for abuse due to coercive influences that may adversely affect offenders' capacity to give voluntary consent to participate in research conducted in correctional settings. Despite this concern, to date there have been almost no systematic scientific investigations of the extent to which offenders themselves perceive that coercion occurs in these settings or that it is likely to influence their decisions about research participation. In a sample of over 600 ethnically diverse men and women recruited from various prisons and community corrections facilities in Texas and Florida, we used a vignette-based survey concerning a hypothetical research project to measure and compare offenders' global perceptions of coercive processes, as well as the differential salience and perceived coercive influence of specific factors (e.g., coercion by other inmates, inducements from staff). Somewhat surprisingly, across multiple outcome measures our participants on average reported relatively little in the way of significant coercive influences on their capacity to make voluntary decisions concerning research participation. Implications and directions for future research on coercive influences in offender research are discussed.  相似文献

Although the use of semantic information about the world seems ubiquitous in every task we perform, it is not clear whether we rely on a scene’s semantic information to guide attention when searching for something in a specific scene context (e.g., keys in one’s living room). To address this question, we compared contribution of a scene’s semantic information (i.e., scene gist) versus learned spatial associations between objects and context. Using the flash-preview–moving-window paradigm Castelhano and Henderson (Journal of Experimental Psychology: Human Perception and Performance 33:753–763, 2007), participants searched for target objects that were placed in either consistent or inconsistent locations and were semantically consistent or inconsistent with the scene gist. The results showed that learned spatial associations were used to guide search even in inconsistent contexts, providing evidence that scene context can affect search performance without consistent scene gist information. We discuss the results in terms of hierarchical organization of top-down influences of scene context.  相似文献
