OBJECTIVE: The aim of this study was to examine the impact of childhood sexual abuse (CSA) on clinical characteristics and premature termination of treatment in anorexia nervosa (AN). METHOD: The participants were 77 consecutive patients with AN admitted to an inpatient eating disorders unit. The patients were assessed in terms of eating disorder symptoms, general psychopathology, and CSA history at admission to hospital. RESULTS: Thirty-seven patients (48%) reported a history of CSA before the onset of the eating disorder. Individuals with a history of CSA reported significantly greater psychiatric comorbidity, including higher levels of depression and anxiety, lower self-esteem, more interpersonal problems, and more severe obsessive-compulsive symptoms. Patients with the binge-purge subtype of AN (AN-BP) were significantly more likely to report a history of CSA prior to the onset of the eating disorder as compared with patients with the restricting subtype (AN-R) of the illness (65% of the AN-BP patients vs. 37% of the AN-R patients; p<.02). Contrary to our predictions, abused patients were not significantly more likely to dropout of treatment overall. However, patients of the binge-purge subtype (AN-BP) with a history of CSA were significantly more likely to terminate treatment prematurely as compared with the other patients. CONCLUSIONS: Consistent with previous findings, the present results indicate that the prevalence of CSA is high among individuals seeking inpatient treatment for AN. A history of CSA was associated with greater psychiatric disturbance overall and a higher rate of dropout for patients of the binge-purge subtype.  相似文献

ABSTRACT

This article is situated in the context of an intensified discourse within which academic developers are being asked to provide evidence of impact, and argues that theoretical models currently used are imprecise and fail to capture the variation in outcomes from professional development activities. Through reference to previous research on how teachers' thinking can be described in relation to various thinking-zones, and how teachers notice and respond to signs of student learning, we suggest a more fine-grained perspective. Furthermore, we argue that improved models for design and evaluation of professional development might prove crucial for academic development as a profession.  相似文献

This paper uses a case study approach to examine how the heteronormative nature of one middle school setting and classroom environment shapes the climate of safety, support and learning for LGBTQ students when they are engaged in studying a novel with a gay character. Heteronormative environments inform and shape positioning of and by students and teacher, impacting how knowledge is created, processed and applied. LGBTQ literature integrated into the classroom curriculum invites opportunities for possibilities through windows and mirrors for exploration of the world and self. Heteronormativity, positioning and LGBTQ literature thereby become interactive catalysts that create and foreclose possibilities and impossibilities for student learning. Three themes emerged from the study that reveal positioning and possibilities when studying a text with a gay character: (1) the school environment and classroom context positioned students as heterosexual; (2) students and teacher positioned gender performance and sexual identity as other; and (3) while the text acted as both a window and a mirror, the teacher and students consistently framed different, and sometimes contradictory, views for each other. Together, these themes reflect a nested understanding of gender performance and sexual identity that subscribed to heterosexual norms and limited possibilities for LGBTQ students.  相似文献

Academic research productivity has traditionally been measured via publication counts and citations. These measures have been used to evaluate both individuals and academic departments. An additional measure of research productivity has been emerging in recent years: research grant acquisition. The present analysis explores this method of evaluating research productivity. We consider the number of grants individuals have been awarded, the types of granting agencies, and the total amount of grant dollars individuals have received. Additionally, we explore these measures at the aggregated level of criminal justice departments. We find that grant acquisition is a unique, useful way to measure research productivity, that is related to traditional publication count approaches for both individuals and departments.  相似文献

To date, assessment validity research on non-native English speaking students in the United States has focused exclusively on those who are presently English language learners (ELLs). However, little, if any, research has been conducted on two other sizable groups of language minority students: (a) bilingual or multilingual students who were already English proficient when they entered the school system (IFEPs), and (b) former English language learners, those students who were once classified as ELLs but are now reclassified as being English proficient (RFEPs). This study investigated the validity of several standards-based assessments in mathematics and science for these two student groups and found a very high degree of score comparability, when compared with native English speakers, for the IFEPs, whereas a moderate to high degree of score comparability was observed for the RFEPs. Thus, test scores for these two groups on the assessments we studied appear to be valid indicators of their content knowledge, to a degree similar to that of native English speakers.  相似文献

In some institutions offering certification for bilingual education and ESL teachers, the corresponding mainstream programs do little to ready their students to work effectively with language minority children. Yet today's mainstream classrooms are linguistically and culturally diverse, and all teachers must appreciate the role of language and culture in teaching and learning. This study describes one effort to consciously combine preservice bilingual and mainstream education teachers in a bilingual education methods cohort. Students reported promising gains in cross-cultural understanding and in cross-program appreciation. Some losses took place as well, however, and further innovation and research are needed in order to ensure that such efforts to combine programs strengthen, but not weaken, each program.  相似文献

Nearly 60% of students with disabilities who attend postsecondary institutions attend community colleges. Individuals with disabilities paralleling their peers without disabilities need the postsecondary education opportunity to develop vocational skills, the time to mature, and the experience of living with others. A transition program, a K–12 and community college partnership, was developed to support students in this mission. A narrative inquiry methodology was utilized to understand the community college experience of students with disabilities in a transition program. Findings indicate that the program benefited the individuals. It did this by supporting completion of a vocational program leading to gainful employment and as a transition into adult roles and status. The program also provided opportunities that enhanced the individuals' self-esteem, and it facilitated the individuals becoming more independent and responsible.  相似文献

Committed to improving how their various programs serve student learning, Taran Cardone, Elizabeth Stoll Turton, Gerald Olson, and Marcia Baxter Magolda describe how their participation in Miami University's Community of Practice on Engaged Learning (COPEL) helped them create developmentally appropriate, learning‐centered approaches that support the complex task of student self‐authorship.  相似文献

Previous research has established that student learning is influenced by how accurately teachers perceive student academic ability. But studies rarely investigate the degree to which inaccuracies in teacher perceptions exacerbate demographic inequality in academic ability. Using a sample of almost 14,000 children from the Early Childhood Longitudinal Study, Kindergarten Cohort, we found that children whose literacy skills are overestimated by their teachers typically gain more literacy skills during kindergarten. Conversely, children whose skills are underestimated learn less. It is important to note that the skills of socioeconomically disadvantaged children are on average underestimated. As a result, inequalities in kindergarten literacy development stem in part from the links between teacher misperceptions and student background. We also explored the extent to which these relationships operate through practices associated with ability grouping. We found instructional grouping to be a weak facilitator of the link between teacher perceptions and student learning, suggesting the need for further research that identifies the social and structural classroom characteristics that link teacher perceptual accuracy to student learning.  相似文献
