Most work on ethnicity tends to focus on daytime health rather than how aspects of ethnicity affect nighttime functioning. The current study examined how discrimination and ethnic identity relate to sleep architecture and fatigue in 37 African Americans and 56 Caucasian Americans. The authors conducted sleep monitoring with standard polysomnography. African Americans had less slow-wave sleep and reported more physical fatigue than did Caucasian Americans (ps < .05). The authors conducted path analyses to examine relationships between ethnic identity, perceived discrimination, sleep, and fatigue. Perceived discrimination mediated ethnic differences in Stage 4 sleep and physical fatigue. Individuals who reported experiencing more discrimination had less Stage 4 sleep and reported experiencing greater physical fatigue (ps < .05). Although ethnic identity did not mediate ethnic differences in sleep latency, there was a significant relationship between ethnic identity and sleep latency, indicating that individuals who felt more connected to their ethnic group had more difficulty falling asleep while in the hospital (p < .05). These observations suggest that the effects of stress related to one's ethnic group membership carry over into sleep. 相似文献

Specific phobia (SP) typically onsets in childhood and frequently predicts other mental health disorders later in life. Fortunately, childhood SP can be effectively treated with cognitive behavior therapy (CBT), including the exposure-based one-session treatment (OST) approach. Despite empirical support for CBT and OST, clinicians, for various reasons, frequently fail to implement exposure-based therapy in routine clinical practice, including perceived difficulties in implementing exposure. Virtual reality (VR) exposure therapy may overcome some of these challenges and provides an alternative modality of therapy. This preliminary study examined the efficacy of VR OST for 8 children with a SP of dogs (aged 8–12 years) (M = age 10.25; SD = 2.11) using a multiple-baseline controlled case series. Following a stable baseline period of either 2, 3, or 4 weeks, it was expected that specific phobia severity would significantly decline after VR OST and remain improved over the 3-week maintenance phase. Assessments were conducted posttreatment and at 1-month follow up (study end-point). It was found that phobia symptoms remained relatively stable across the baselines, with significant reductions from pretreatment to posttreatment and to follow-up on clinician severity ratings (pre- to post- g = 1.12; pre- to follow-up g = 2.40), target symptom ratings (g = 1.14; 1.29), and behavioral avoidance (g = -1.27; -1.96). The treatment was also associated with clinically significant outcomes, whereby at one-month follow up, 75% of children were considered “recovered” and 88% completed the BAT (interacted with their feared stimuli). This study provides support for the effectiveness of VR OST. 相似文献

Across three studies, two experiments, and two different countries (Israel and the United States), we examine how perceptions among members of the public regarding the motives of terrorists' influence support for counterterrorist policy. We find that while perceptions that terrorists are motivated by “hatred” (rather than by a “lack of opportunity”—economic or otherwise) strongly correlate with support for harsher counter-tactics, and that these perceptions can be changed by providing information from “experts” on the “true” motivations of the outgroup, these changes in perception do not appear to cause change in support for counterterrorism policy. Our findings suggest that among the public, counterterror policy is not as instrumentally driven as much current research assumes. 相似文献
