For the last twenty years, the concept of content area reading has been a major topic in the research and professional literature. This notion, however, was not an invention of the 60s; research contributing to this area is documented fifty years earlier. Another recent trend has been the emergence of ethnography as a research tool in educational settings. This, too, has been employed since the 1920s. In fact, one of the more extensive early studies incorporating an enthnographic design for content reading was undertaken by McCallister. This review and reanalysis of his study aid in judging its value and accuracy. 相似文献

Psychiatric and Self‐Injury Profiles of Adolescent Suicide Attempters versus Adolescents Engaged in Nonsuicidal Self‐Injury 下载免费PDF全文
Kerri L. Kim PhD Thania Galvan BA Megan E. Puzia BA Grace K. Cushman BS Karen E. Seymour PhD Roshani Vanmali BS Richard N. Jones ScD Anthony Spirito PhD Daniel P. Dickstein MD 《Suicide & life-threatening behavior》2015,45(1):37-50
To better delineate the unique correlates of self‐injurious behaviors (SIB), psychiatric profiles of mutually exclusive groups of adolescents who made a suicide attempt (SA) versus those engaged in nonsuicidal self‐injury (NSSI) were examined. Contrary to hypotheses, the NSSI group endorsed earlier onsets of SIB and suicidal ideation (SI), as well as higher rates of depression and anxiety compared with their SA counterparts. Future work is warranted to understand the role of SI, including duration of SI and anxiety in the development of NSSI, and to identify risk and resiliency factors useful in predicting an adolescent's SIB status. 相似文献

Lifetime and 12‐Month Nonsuicidal Self‐Injury and Academic Performance in College Freshmen 下载免费PDF全文
Glenn Kiekens MSc Laurence Claes PhD Koen Demyttenaere MD PhD Randy P. Auerbach PhD Jennifer G. Green PhD Ronald C. Kessler PhD Philippe Mortier MD Matthew K. Nock PhD Ronny Bruffaerts PhD 《Suicide & life-threatening behavior》2016,46(5):563-576
We examined whether nonsuicidal self‐injury (NSSI) is associated with academic performance in college freshmen, using census‐based web surveys (N = 7,527; response = 65.4%). NSSI was assessed with items from the Self‐Injurious Thoughts and Behaviors Interview and subsequently linked with the administratively recorded academic year percentage (AYP). Freshmen with lifetime and 12‐month NSSI showed a reduction in AYP of 3.4% and 5.9%, respectively. The college environment was found to moderate the effect of 12‐month NSSI, with more strongly reduced AYPs in departments with higher‐than‐average mean departmental AYPs. The findings suggest that overall stress and test anxiety are underlying processes between NSSI membership and academic performance. 相似文献

Coping Card Usage can Further Reduce Suicide Reattempt in Suicide Attempter Case Management Within 3‐Month Intervention 下载免费PDF全文
Ying‐Chuan Wang MS Ling‐Yu Hsieh MS Ming‐Yu Wang MD Cheng‐Hsiang Chou PhD Min‐Wei Huang PhD Huei‐Chen Ko PhD 《Suicide & life-threatening behavior》2016,46(1):106-120
This randomized controlled trial was designed to evaluate the effectiveness of using crisis coping cards (n = 32) in the case management of suicide prevention compared with case management without the use of coping cards (n = 32) over a 3‐month intervention period. The generalized estimating equation was used to examine the interaction effect between treatments and time on suicide risk, depression, anxiety, and hopelessness. Results indicated that subsequent suicidal behaviors, severity of suicide risk, depression, anxiety, and hopelessness were reduced more in the coping card intervention group compared to the case management only group. Moreover, for the survival curves of time to suicide reattempt, the coping card group showed a significantly longer time to reattempt than the case management only group at 2‐month and 3‐month intervention periods. 相似文献

Rural versus urban rates of suicide in current patients of a large area mental health service in Australia were compared. Suicide deaths were identified from compulsory root cause analyses of deaths, 2003–2007. Age‐standardized rates of suicide were calculated for rural versus urban mental health service and compared using variance of age‐standardized rates with 95% confidence intervals. There were 44 suicides and the majority (62%) were rural. Only urban patients used jumping from heights as a method of suicide (4/17; p = 0.02). Rural patients had 2.7 times higher rates of suicide, similar to findings for rural versus urban community suicides and may reflect the underlying community rates, differences in mental health service delivery, or socioeconomic disadvantage. 相似文献

Changing Rates of Suicide Ideation and Attempts Among Inuit Youth: A Gender‐Based Analysis of Risk and Protective Factors 下载免费PDF全文
Sarah L. Fraser PhD Dominique Geoffroy MA Eduardo Chachamovich MD PhD Laurence J. Kirmayer MD 《Suicide & life-threatening behavior》2015,45(2):141-156
Inuit in Canada currently suffer from one of the highest rates of suicide in the world. The objective of this study was to explore the prevalence of suicide ideations and attempts among 15–24 year olds living in Nunavik, Québec, and to explore risk and protective factors of suicide attempts as a function of gender. A cross‐sectional survey was conducted in 2004 across Nunavik. Univariate and multivariate logistic regressions were conducted. A total of 22% of young males and 39% of females adults reported past suicidal attempts. Gender differences were observed in relation to associated risk and protective factors as well as degree of exposure to risk factors. Suicide prevention must include alcohol and drug prevention programs and rehabilitation services, interventions to reduce physical and sexual violence and their long‐term impacts on Inuit youth, as well as exposure to culturally meaningful activities. 相似文献
