This study profiles the characteristics of adolescent suicide attempters and the treatment they received in a pediatric emergency room (ER). A retrospective chart review of 4,072 adolescents seen in the ER at a children's hospital (CH) from July 1984 to June 1985 was undertaken. Twenty-seven adolescents who had deliberately injured themselves were identified. The average age was 14 years 7 months (range 11-19 years). Fifty-two percent of the patients were white and 78% were female. Ingestion was the most common method (78%), followed by attempted hanging (11%), and wrist laceration (7%). After evaluation by a pediatrician in the ER, 30% of the patients were treated and released, 11% were transferred directly to a psychiatric hospital, and 59% were admitted to the CH, with an average hospital stay of 1.88 days. Once hospitalized, consultations from psychiatry (81%), social service (50%), psychology (19%), and neurology (6%) were obtained. At the time of discharge from either the ER or CH, the patients had a variety of plans for ongoing care, with 52% being referred to outpatient counseling, 37% being transferred to a psychiatric hospital, and 11% having no documented plan for ongoing care. These results demonstrate that the evaluation of suicidal adolescents cared for in a pediatric facility may be episodic and suggest the need for a comprehensive program to approach the problem.  相似文献

Fifty-eight male and 66 female junior high school students were examined to determine their preferences for sex of counselor under personal/social and educational hypothetical counseling situations. Girls demonstrated a definite same-sex preference for both counseling situations, while boys preferred male counselors for personal/social counseling and had opposite-sex preferences for educational counseling. Implications of the findings are discussed in light of earlier contradictory results from research on college students.  相似文献

Secondary revision is a highly provocative concept arising out of Freud's attempts to explain the construction of dreams, but it remains relatively ill-defined. It includes three related, yet by no means identical aspects of the process by which the dream acquires its more or less final form during the experiencing, the remembering, and the telling. It represents one of the most interesting hypotheses dealing with the fluid world between sleeping and waking, a field which still presents us with a host of unanswered questions. Secondary revision not only reflects the higher levels of the dreamer's mental functioning superimposed on his biological substructure, but it also operates as a sensitive indicator of the cultural factors which have helped mold his personality. These factors include both the subculture of the analytic situation and the impact of society in the larger sense. I make reference to individual dreamers in analysis and to the world of dreams recorded in the past from our own and other cultures.  相似文献

The purpose of this work is to explore the phenomenon of negativism and the analyst's response to it during the course of analytic work with a patient in whom negativism is a central behavioral pattern. Melville's short story, "Bartleby the Scrivener," describing in telling detail the response of a sympathetic lawyer to profound and pervasive negativism in his legal scribe, is discussed as a literary analogy to the analyst-analysand dyad. Aspects of the concept of negativism within psychoanalysis are discussed. The potential usefulness of understanding certain unexpected countertransference responses to pervasive negativism is explored, as this is a relatively neglected area of psychoanalytic technique. A case is presented describing the analysis of a patient whose character, like Bartleby's, is a mixture of profound negativism along with schizoid, obsessional, and masochistic elements.  相似文献

In three experiments, the effect of target luminance on estimates of visual persistence was determined on a popular successive-field task. Even though the experiments differed from each other only in terms of minor changes in stimulus conditions, very different effects were obtained across the three experiments. The different findings were attributed to the often overlooked roles of masking and target degradation on tasks of persistence. Implications for the numerous contradictory findings in the persistence literature are discussed, and the current popularity of the successive-field task is questioned.  相似文献

Subjects studied 12-word lists for free recall. During presentation of the lists, each word was followed by a supraspan sequence of digits, which the subjects tried to reproduce. This task, unlike those used in previous research with this continual distractor procedure, presumably taxed immediate memory capacity to the full. Nevertheless, the word recall data showed a pronounced recency effect. Moreover, the magnitude of the recency effect was found to be just as great with this task as with a more typical task in which the demands on immediate memory are likely to be fewer. These findings reinforce the emerging view that the recency effect need not be the product of immediate memory.  相似文献

The author outlines his clinical observations during the "middle game" of psychoanalysis, leading to recognition that structural change is taking place. "Middle game," "structure," process, and content are defined and critically discussed. Illustrative clinical vignettes are offered. The presentation emphasizes the importance of an active and resolving transference "struggle"; in addition, more traditionally noted criteria are briefly touched on, e.g., development of observing ego and treatment alliance, changes in dream function and communication, and the reviewing of the neurosis and transference during the termination phase as instances of mourning and working through. The concept of optimal psychobiological function in the service of a homeostatic principle is discussed.  相似文献
