Currently, suicide is the third leading cause of death among youth 18 to 24 years of age and the second leading cause of death on college campuses. A sample of students (N = 1,019) from three midwestern universities were surveyed regarding their perceived self‐efficacy in identifying suicide warning signs and campus suicide intervention resources. The results indicated that 11% strongly believed they could recognize a friend at suicidal risk, while 17% strongly believed they could ask a friend if he or she was suicidal. Students who had received high school suicide prevention education and who had ever had a family member or friend express suicidal thoughts to them were those most confident in recognizing a friend at risk, asking a friend if he/she is suicidal, and helping a friend to see a counselor. Most (71%) were not aware of on‐campus help resources. These findings underscore the importance of suicide prevention education throughout the high school and college years.  相似文献

This paper explores the ethical and conceptual implications of the findings from an empirical study of decision-making capacity in anorexia nervosa. In the study, ten female patients aged 13 to 21 years with a diagnosis of anorexia nervosa, and eight sets of parents, took part in semi-structured interviews. The purpose of the interviews was to identify aspects of thinking that might be relevant to the issue of competence to refuse treatment. All the patient participants were also tested using the MacCAT-T test of competence. This is a formalised, structured interviewer-administered test of competence, which is a widely accepted clinical tool for determining capacity. The young women also completed five brief self-administered questionnaires to assess their levels of psychopathology.The issues identified from the interviews are described under two headings: difficulties with thought processing, and changes in values. The results suggest that competence to refuse treatment may be compromised in people with anorexia nervosa in ways that are not captured by traditional legal approaches or current standardised tests of competence.  相似文献

We examined the impact of risk and protective factors on the odds that African American adolescents seriously think about or attempt suicide. Data from students in grades 5–12 in a mostly urban, southeastern U.S. school district were analyzed. Findings support earlier work documenting differences in gender and grades. Risk factors were uniformly significant in understanding both ideation and attempts. Protective factors were not consistent predictors; the lowering role of religious protective factors was limited, though student's belonging to or their perception of belonging to a spiritual community was a significant factor in lowering the odds of suicide ideation.  相似文献

The mechanism by which Russian native speakers store and retrieve Russian and English words from lexical memory was investigated in two experiments in which fluency of retrieval was compared for categorical and alphabetic cues. We hypothesized that fluency in Russian would be higher for categorical cues but that fluency in English would be higher for alphabetical cues because native language words would have been stored by meaning, while second-language words would have been stored according to dictionary usage. Subjects retrieved more Russian than English words with categorical cues, but their retrieval was the same for the two languages with alphabetic cues. In addition, fluency was greater overall with alphabetical than categorical cues. We attributed the greater fluency in Russian with the categorical cues to the early age at which the concepts were acquired, which made them more accessible in the native language. These findings support the idea that access codes for words may vary depending upon how they are originally learned.This research was supported by Research Grants AFOSR 89-0442 and F49620-92-J-0119 from the U.S. Air Force Office of Scientific Research to Joan Gay Snodgrass. We are indebted to an anomymous reviewer for constructive comments on an earlier version of this article.  相似文献

In a large-scale study of senior police officers in Great Britain (Superintendent and Chief Superintendent ranks), the role of coping in the stress-strain relationship was explored. There was no indication of a direct impact of coping on physical well-being nor was there any evidence of a direct effect on job satisfaction, but coping was related to mental health. Coping also exhibited a direct relationship to subjectively perceived job stress. Moreover, coping moderated the relationship between job stress and job satisfaction, but a buffering influence was not observed on the job satisfaction-health linkages. Job satisfaction had a direct impact on both mental and physical ill-health (showing high satisfaction was associated with superior physical and psychological health). Likewise, there was a direct relationship between overall job stress and job satisfaction.  相似文献
