Suicides among older adults in the United States and Canada in the last decade have accounted for an increasing share of all suicides. In both countries the use of firearms among older adults has steadily increased. Despite these trends, little is known about the extent to which crisis centers are prepared to prevent elder suicide. A survey of AAS-listed crisis prevention centers examined the training, knowledge, and current practices relevant to elder suicide among personnel in 321 crisis prevention centers in both countries. Results revealed insufficient training, a lack of familiarity with recent suicide trends, and limited outreach to older adults. 相似文献

Assessment of methods for measuring social support 总被引:2,自引:0,他引:2
A rapidly expanding literature documents the effects of social support on physical and psychological well-being. Although definitions vary, most include both tangible components (e.g., financial assistance and physical aid) and intangible components (e.g., encouragement and guidance). Social support has been implicated in the mediation of stressful life events, recovery from illness, and increased program adherence. There are many inconsistent findings in the literature, however, and it is difficult to resolve discrepancies because measures of social support vary widely from study to study. To guide in the selection of measurement methods for research and applied work, 23 techniques for assessing social support are reviewed and evaluated. Criteria for favorable evaluation included reliability coefficients greater than .8 and documentation of validity. Correlations between various social support and criterion measures are simulated in order to demonstrate the consequences of choosing a measure with low reliability. Scale developers reported reliability data for 19 of the reviewed measures. Internal consistency coefficients ranged from .31 to .98. Test-retest coefficients ranged from .22 to .96. At least some validity documentation was available for 13 of the scales. Discriminant validity evidence, however, is almost universally absent. Despite psychometric weaknesses and variability among the scales, researchers have several instruments available to them. 相似文献

Recently, several theories of decision making and probability judgment have been proposed that take into account ambiguity (Einhorn and Hogarth, 1985; Gardenfors and Sahlin, 1982). However, none of these theories explains exactly what the psychological causes of ambiguity are or addresses the issue of whether ambiguity effects are rational. In this paper, we define ambiguity as the subjective experience of missing information relevant to a prediction. We show how this definition can explain why ambiguity affects decisions in the ways it does. We argue that there are a variety of rational reasons ambiguity affects probability judgments and choices in the ways it does. However, we argue that the ambiguity effect does not cast doubt on the claim that utility theory is a standard of rational choice. Rather, we suggest that the effect of ambiguity on decisions highlights the fact that utility theory, like any normative model of decision making only prescribes the optimal decision, given what one knows. 相似文献

Zajonc's (1965) drive theory explanation argues that greater arousal tends to impair performance on difficult tasks. The hypothesis that arousal generated by “pressure situations” during major league baseball games would hinder batting performance—a difficult task—was tested by examining such performance during the 1989 season. Six “pressure situations” were identified, some occurring during the late innings of close games and others occurring throughout the game when there were two outs. Two measures of batting performance (batting average and slugging average) were employed. Results indicated broad support for the hypothesis. Reasons for this pattern are discussed, as are possible alternative explanations for these findings. 相似文献

Since the Supreme Court's decision in Faretta v. California (1975), courts have generally permitted defendants to represent themselves, as long as they are competent to do so. The problem lies in the definition of competency to waive counsel, which has been vaguely defined by the courts. Little is known about the frequency of, or reasons for, attempts to waive counsel, about the process of forensic evaluation of such competency, and about the success of such attempts. The authors briefly review the case law on competency to waive representation, report on a longitudinal prospective study of these issues in a population of defendants referred to an inpatient forensic facility for evaluation of all types of competency related to their criminal prosecutions, and discuss the significance of the issue for forensic clinicians. A key question for courts, lawyers, and clinicians is whether a competency evaluation can be invoked to overcome a defendant's constitutional rights to self-representation and bail. 相似文献

This paper explores the notion of truthfulness in research on conversational remembering. It argues that people's accounts of past events, before they can be taken as data on the cognitive workings of memory, need to be examined as contextualized and variable productions that perform pragmatic and rhetorical work; no one version can be taken as a person's real memory. The consequences of this discourse-analytical perspective are examined first through a critical discussion of Ulric Neisser's study of John Dean's testimony to the senate ‘Watergate’ committee. The issues are then explored more deeply in an analysis of reportings of a different event, in which similar (Watergate-like) issues of memory, truth and accuracy are also at issue. It is argued that: (a) all of Neisser's three kinds of memory–verbatim, gist and ‘repisodic’–involve problematical assumptions concerning their relation to some true, original event; and (b) that Dean's accounts of his memory and his displays of memory should be approached as occasioned productions oriented pragmatically to the assignment of guilt and avoidance of scapegoating. Through an analysis of newspaper reports (based on memory) of a controversial briefing given by the then British Chancellor of the Exchequer, Nigel Lawson, we then examine: (a) how discourse about what could be used as an arbiter of truth was rhetorically organized; (b) how participants' versions of events were constructed rhetorically, as parts of arguments; (c) that both sides in the dispute maintained the coherence of their positions by a form of error accounting similar to that used by Neisser with respect to Dean. It is suggested that cognitive psychologists, whether working in the laboratory or attempting to do real-world studies of everyday remembering, need to avoid simplistic notions of true original events, and can do so by addressing the rhetorical organization of participants' memory accounts. 相似文献

A mother's commitment to use violence if necessary to protect her children is not incompatible with pacifism, if pacifism is understood as the commitment to end war and war is understood as the use of violence as a political tool. 相似文献

A general way of describing multiple-choice questionnaires for on-line presentation is described. Some of the important features supported include random ordering of and sampling among questions, substitution of specific-question text into boilerplate question and response formats, a limited ability to bypass irrelevant questions, experimenter editing of response arrays, and automatic production of hard-copy versions of the questionnaire for use during computer breakdowns and for archival documentation. All editing operations on both questionnaires and response data create audit trails for future reference. 相似文献

Two experiments are described that measured lexical decision latencies and errors to five-letter French words with a single higher frequency orthographic neighbor and control words with no higher frequency neighbors. The higher frequency neighbor differed from the stimulus word by either the second letter (e.g.,astre-autre) or the fourth letter (chope-chose). Neighborhood frequency effects were found to interact with this factor, and significant interference was observed only tochope-type words. The effects of neighborhood frequency were also found to interact with the position of initial fixation in the stimulus word (either the second letter or the fourth letter). Interference was greatly reduced when the initial fixation was on the critical disambiguating letter (i.e., the letterp inchope). Moreover, word recognition was improved when subjects initially fixated the second letter relative to when they initially fixated the fourth letter of a five-letter word, but this second-letter advantage practically disappeared when the stimulus differed from a more frequent word by its fourth letter. The results are interpreted in terms of the interaction between visual and lexical factors in visual word recognition. 相似文献
