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

Reviews, compares and evaluates a self-justijication and a decision theoretical conceptualization of equity. It is argued that the latter approach reveals an important and often neglected distinction between equity as a goal of social interaction and equity as an interpersonal strategy employed in rhe pursuit of other valued goals. Associated problems of definition and measurement are discussed. After a review of relevant research it is concluded that equity serves predominantly as an accommodative interpersonal strategy, and that future research should focus on analyzing the various functional bases of equity, their relationships, and their eflects on behaviour. 相似文献

We reconcile competing theories of the role of phonological memory in reading development, by uncovering their dynamic relationship during the first 5 years of school. Phonological memory, reading and phoneme awareness were assessed in 780 phonics‐educated children at age 4, 5, 6 and 9. Confirmatory factor analyses demonstrated that phonological memory loaded onto two factors: verbal short‐term memory (verbal STM; phonological tasks that loaded primarily on serial order memory) and nonword repetition. Using longitudinal structural equation models, we found that verbal STM directly predicted early word‐level reading from age 4 to 6, reflecting the importance of serial‐order memory for letter‐by‐letter decoding. In contrast, reading had no reciprocal influence on the development of verbal STM. The relationship between nonword repetition and reading was bidirectional across the 5 years of study: nonword repetition and reading predicted each other both directly and indirectly (via phoneme awareness). Indirect effects from nonword repetition (and verbal STM) to reading support the view that phonological memory stimulates phonemically detailed representations through repeated encoding of complex verbal stimuli. Similarly, the indirect influence of reading on nonword repetition suggests that improved reading ability promotes the phoneme‐level specificity of phonological representations. Finally, the direct influence from reading to nonword repetition suggests that better readers use orthographic cues to help them remember and repeat new words accurately.

Scholars are paying increasing attention to the “dark side” of citizenship behavior. One aspect of this dark side that has received relatively scant attention is “helping pressure”—an employee's perception that s/he is being encouraged to, or otherwise feels that s/he should, enact helping behavior at work. Drawing from theory associated with work stress, we examine affective and cognitive mechanisms that potentially explain why helping pressure, counterintuitively, may lead employees to engage in deviant behavior instead. Beyond examining these possible mechanisms, we also answer calls to identify a potential buffer to these effects. Drawing from self-determination theory, we examine how an employee's intrinsic motivation for citizenship may lessen the deleterious consequences of helping pressure at work. In two studies (a within-individual experience-sampling study and a two-wave between-individual study), we find consistent evidence that helping pressure has a positive indirect relationship with deviant behavior through increased negative affect. Further, we find evidence that intrinsic motivation for citizenship weakens the positive relationship of helping pressure with negative affect, buffering the indirect effect on subsequent deviant behavior. Theoretical and practical implications of these findings for the study of helping pressure at work are discussed. 相似文献

Researchers have suggested that bystander behaviors and victim coping play an important role in counteracting the negative effects of bullying. The current study investigated the relationship between students’ ratings of coping effectiveness when addressing bullying and their behaviors as bystanders when witnessing bullying. Surveys were administered in a Midwestern, suburban school district. Some associations between perceptions of coping effectiveness and bystander behavior supported our hypotheses (e.g., constructive coping associated with defending bystander behaviors, externalizing associated with pro-bullying behaviors). However, some findings did not support hypothesized relationships. For example, higher ratings of effectiveness for cognitive distancing as a coping strategy were associated with increased defending behaviors as a bystander. Gender moderated some of these relationships. Pro-bullying bystander behavior was associated with increased ratings of cognitive distancing and decreased reports of constructive coping effectiveness for girls. Implications for future research and practice are discussed. 相似文献

Behavioral activation (BA), an effective treatment for depression, has recently been receiving attention as a possible intervention for PTSD. BA interventions could be particularly useful in treating underserved populations (i.e., individuals with lower socioeconomic status). A literature search was conducted, which identified seven outcome studies that examined the effectiveness of stand‐alone BA treatment for individuals with PTSD. All studies identified for this brief review demonstrated clinically significant reductions in PTSD symptoms using BA as an intervention. A meta‐analysis of these few studies revealed a nonsignificant effect (Cohen's d = 0.713, p = .512) despite reporting an average symptom reduction of 25.8%. Other studies utilizing BA treatment for PTSD do so in tandem with other interventions and were excluded from analysis. This brief review summarizes the literature on the use of BA as a stand‐alone treatment for PTSD and suggests that future research seek to confirm the usefulness of BA as a potential treatment modality for mental health‐care providers treating individuals with PTSD. 相似文献

Researchers have identified difficulties associated with the use of traditional Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) validity scales with survivors of traumatic events. A new scale, the Infrequency-Posttraumatic Stress Disorder scale (Fptsd), was created from MMPI-2 items that were infrequently endorsed by 940 male combat veterans presenting for treatment at the posttraumatic stress disorder (PTSD) clinics of 2 Veterans Affairs Medical Centers. A variety of statistical methods were implemented that preliminarily established Fptsd's validity with a validation sample of 323 additional PTSD-diagnosed combat veterans. Results indicate that, relative to previously established validity and overreporting scales (F, Fb, and Fp), Fptsd was significantly less related to psychopathology and distress and better at discriminating simulated from genuinely reported PTSD. Clinical implications are discussed concerning the use of Fptsd to assess disability-seeking veterans suspected of overreporting PTSD symptoms. 相似文献
