This study considers links between the number of types of violence to which women have been exposed, depression, and executive functions (EFs). Substantial research has established EF deficits among depressed individuals as well as individuals exposed to trauma. Studies have also indicated a relationship between trauma exposure and depressive symptoms across a range of traumatic events, such as combat exposure, motor vehicle accidents, natural disasters, and assaults. This study examines this relationship in an ethnically diverse community sample of 93 women exposed to interpersonal violence who completed a battery of EF tasks that assessed processing speed, working memory, response inhibition, and set shifting. Women reported an average of 5.8 types of interpersonal violence events. The number of types of interpersonal violence events was significantly related to depressive symptoms, although not EF performance. Specific EFs, such as working memory and response inhibition, were positively related to depressive symptoms.  相似文献

Longitudinal studies of loneliness among older people are comparatively rare. At 8 years after the initial survey in 1999–2000, we followed up on the 999 people aged 65+ years who were living in the community in the United Kingdom. We found that 583 participants were still alive, and 287 (58%) participated in the follow-up survey. The overall prevalence of loneliness at both time points was very similar, with 9% reporting severe loneliness; 30% reporting that they were sometimes lonely, and 61% reporting that they were never lonely. We developed a 12-category typology to describe changes in loneliness across the follow-up period and report that 60% of participants had a stable loneliness rating, with 40–50% rating themselves as never lonely, and 20–25% rating themselves as persistently lonely; 25% demonstrated decreased loneliness, and approximately 15% demonstrated worse loneliness. Changes in loneliness were linked with changes in marital status, living arrangements, social networks, and physical health. Importantly improvements in physical health and improved social relationships were linked to reduced levels of loneliness. This result suggests that strategies to combat loneliness are not confined to the arena of social interventions such as befriending services, which aim to build and support social embeddedness, but may also result from the treatment of chronic and long-term health conditions.  相似文献

The purpose of this study was to explore differences in body satisfaction among female adolescents 14 to 18 years of age. Principal components analysis of a body cathexis measure completed by 751 high school cheerleaders indicated that six factors defined the adolescents' attitudes toward their bodies: satisfaction with the midsection and overall appearance, peripheral body parts, hair and face, mouth, hands, and height. An Age x Body Satisfaction multivariate analysis of variance (MANOVA) was conducted; a Bonferroni adjusted alpha of .007 was established for subsequent ANOVAs. Satisfaction with the mouth increased significantly as age increased, and a similar but nonsignificant trend was found for peripheral body parts. The findings contradict previous research reporting no age differences in the body satisfaction of adolescents. Role demands and physical maturation of the cheerleaders may explain differences based on age.  相似文献

Despite a growing literature on social support networks in religious settings (i.e., church-based social support), little is known about mosque-based support among Muslims. This study investigates the demographic and religious behavior correlates of mosque-based social support among a multi-racial and ethnic sample of 231 young Muslims from southeast Michigan. Several dimensions of mosque-based support are examined including receiving emotional support, giving emotional support, anticipated emotional support and negative interactions with members of one’s mosque. Results indicated that women both received and anticipated receiving greater support than did men. Higher educational attainment was associated with receiving and giving less support compared to those with the lowest level of educational attainment. Moreover, highly educated members reported fewer negative interactions than less educated members. Mosque attendance and level of congregational involvement positively predicted receiving, giving, and anticipated emotional support from congregants, but was unrelated to negative interactions. Overall, the study results converge with previously established correlates of church-based emotional support.  相似文献

The objective of the paper is to explore bottom‐up auditory and top‐down cognitive processing abilities as part of long‐term outcome assessment of preterm birth. Fifty‐five adolescents (age 13–15) born with very low birth weight (VLBW) were compared to 80 matched controls born to term, using three consonant‐vowel dichotic listening (DL) instruction conditions (non‐forced, forced‐right and forced‐left). DL scores were correlated with cortical gray matter thickness derived from T1‐weighted structural MRI volumes using FreeSurfer to examine group differences also in the neural correlates of higher cognitive processes. While showing normal bottom‐up processing, VLBW adolescents displayed impaired top‐down controlled conflict processing related to significant cortical thickness differences in left superior temporal gryus and anterior cingulate cortex. Preterm birth with VLBW induces fundamental changes in brain function and structure posing a risk for long‐term neurocognitive impairments. Deficits emerge in situations of increasing cognitive conflict and can be related to measures of executive functions as well as morphology.  相似文献

Previous research has demonstrated multiple beneficial outcomes of communal school organization for teachers and students alike. The current research uses data from a nationally representative sample of 253 public, non-alternative, secondary schools to examine how a communal school organization interacts with school contextual factors, such as school size and racial diversity, to affect school disorder. It was found that more diverse schools are less likely to be communally organized and that communal school organization had a stronger negative effect on school disorder in these more diverse schools. Theoretical and practical implications of these findings are discussed.  相似文献

Abstract

As a way for practitioners to integrate various models of marital therapy into their treatment,a flow chart of the process of psychotherapy with couples is presented. Basic steps and questions to be addressed are sequentially discussed. Resolution of each stage is considered important for movement to following stages. The flow chart, as a device for conceptualizing clients independent of a theoretical approach, allows for intervention strategies to be developed at each process level  相似文献

This study examines social cognitive factors that influence information sharing related to climate change. Survey data were collected in the United States and China. Social and epistemic motivations, negative emotion, and information seeking were significant predictors of information sharing in the U.S. sample. In the Chinese sample, however, social motivation and information seeking were the only significant predictors. These results suggest that psychological collectivism fosters information sharing. For theory development purposes, these findings suggest that besides information seeking and processing, the Risk Information Seeking and Processing model could account for information sharing as well, although evidence only surfaced in the U.S. sample. Practically, this study offers important pathways to improve information sharing related to climate change in the public sphere.  相似文献
