This study reviews the causes of sudden death of 66 schizophrenic patients who presented to the Office of the Chief Medical Examiner (OCME) for the State of Maryland over a 3-year period from 1994 through 1996. We identified an increased incidence of suicide compared with the general population of OCME cases. This observation is consistent with reports by other investigators. The majority of the deaths were the result of natural diseases, mostly atherosclerotic cardiovascular disease. Accidents, suicides, and 1 homicide were also present in this group. 相似文献

The MMPI-2 and the Inwald Personality Inventory were employed to investigate the personality characteristics of dropouts from
a state police academy. A traditional model of training borrowed from military models was used at the academy rather than
a police generated model. Sensitive and independent individuals, more compatible with modern community policing methods may
have rejected police work as a result of the experience. 15 academy completers and 9 dropouts were used in the sample. Analyses
of the scales of the MMPI-2 and the Inwald Personality Inventory identified variables upon which the two groups differed.
The hypothesis that more sensitive, empathic and independent individuals were leaving the academy appeared to be supported. 相似文献

福建省违法犯罪青少年的个性特征研究 总被引:5,自引:0,他引:5
为探讨青少年违法犯罪与个性的关系,采用艾森克个性问卷对621名13-19岁违法犯罪青少年和1371名相应年龄在校学生按不同年龄段和性别进行对照研究,发现16-19岁男性违法犯罪青少年外向性(E)、精神质(P)评分显著高于对照组(P<0.01),13-15岁男性违法犯罪少年精神质(P)、神经质(N)评分显著高于对照组(P<0.01),16-19岁女性违法犯罪青少年神经质(N)评分低于对照组(P<0.05),不同违法犯罪类型之间各个维度无统计学差异,表明外向性、精神质和神经质与男性青少年违法犯罪相关,倾稳性可能与女性青少年违法犯罪有关。 相似文献

The efficacy of lithium carbonate as a treatment for manic-depressive illness has stimulated a reevaluation of the syndrome. In this paper, the authors review the obstacles to timely diagnosis of manic-depressive illness in the adolescent. Three cases are presented demonstrating the usefulness of a unitary concept in which manic-depressive illness is understood and appreciated as having a physiologic basis, manifesting its effects in the total body system. The heterofore diverse and confusing psychological and behavioral symptoms of manic depressive illness in adolescents become intelligible when regarded as secondary phenomena: the psychic experience of the process as filtered through the psychological constitution of the individual adolescent.Supported in part by a grant from Mr. and Mrs. A.
