There is substantial evidence of detrimental psychological sequelae following disasters, including terrorist attacks. The effect of these events on extreme responses such as suicide, however, is unclear. We tested competing hypotheses about such effects by employing autoregressive integrated moving average techniques to model the impact of September 11 and the Oklahoma City bombing on monthly suicide counts at the local, state, and national level. Unlike prior studies that provided conflicting evidence, rigorous time series techniques revealed no support for an increase or decrease in suicides following these events. We conclude that while terrorist attacks produce subsequent psychological morbidity and may affect self and collective efficacy well beyond their immediate impact, these effects are not strong enough to influence levels of suicide mortality. 相似文献

The current study hypothesized that (1) hope would negatively predict burdensomeness, thwarted belongingness, and acquired capability to enact lethal injury; (2) hope would negatively predict suicidal ideation; and (3) the interpersonal suicide risk factors would predict suicidal ideation. Results indicated that hope negatively predicted burdensomeness and thwarted belongingness, but positively predicted acquired capability to enact suicide. Contrary to our second hypothesis, hope did not predict suicidal ideation, but interpersonal risk factors for suicide predicted suicidal ideation. Results are discussed in terms of implications for hope theory and Joiner's (2005) interpersonal risk factors for suicide, and for clinical practice. 相似文献

Population attributable risk (PAR) estimates have been used in suicide research to evaluate the impact of psychosocial and socioeconomic risk factors, including affective disorders, traumatic life events, and unemployment. A parallel concept of preventive fraction (PF), allowing for estimation of the impact of protective factors and effectiveness of preventive interventions, is practically unknown in suicidology. The study authors discuss the application of both concepts to suicide research and prevention, and review literature on the subject. Despite several methodological and conceptual limitations, both PAR and PF are valuable instruments to inform development and evaluation of suicide prevention programs. 相似文献

Gender differences in friendship patterns 总被引:1,自引:0,他引:1
The same-sex and opposite-sex friendship patterns of men and women students from two first-year psychology classes at the University of Waikato in New Zealand were examined. A friendship questionnaire previously used in the United States of America was administered to compare results of the two cultures. Findings from this study support American research suggesting that women are more intimate and emotional in their same-sex friendships than men, and tend to place a higher value on these friendships than men do. In accordance with findings of the American sample, New Zealand women emphasized talking, emotional sharing, and discussing personal problems with their same-sex friends, and men showed an emphasis on sharing activities and doing things with their men friends. Differences between the American and New Zealand samples were shown for men in the number of friends and the intimacy levels of these friendships. New Zealand men preferred numerous but less intimate same-sex friends, while women (as in the United States) showed a preference for a few, close, intimate same-sex friends. Men, in contrast to women, derived emotional support and therapeutic value more from their opposite-sex relationships than their same-sex friendships. Finally, more men than women stated they would not cancel an engagement with an opposite-sex friend in order to go out with a same-sex friend. Results are interpreted as suggesting a need for changes in the current socialization process of males who are taught to repress their emotions and form rather less intimate and possibly less beneficial same-sex friendships than women. 相似文献

This paper reports on an unusual study of survivors of rape and the effects on the victim, her significant male other person, and her parents. All survivors were victims of the same rapist and were interviewed from 21 months to ten years after the event. The study indicates that the long-term effects of rape may be more significant than previous researchers and practitioners thought was the case. Recommendations are given for more effective help for survivors and those close to them.This study was funded by the Ohio Department of Mental Health, Office of Program Evaluation and Research, Columbus, Ohio, 1985. 相似文献

Treatment of the depressed client with low self-esteem, external locus of control, and an absent spouse often is frustrating due to the limitations of modifying the social context. An approach to the problem using a systemic view which is based on examining the notion of power and examining the problems in their context is presented. Interventions which sidestep the temptation of emphasizing self-esteem of the client and, instead, utilize client strengths and interactional dynamics within the marriage are presented. 相似文献

The difference in process and outcome of two therapies conducted by the author with families having a psychotic adolescent is considered. Attention is paid to the fact that in one case the client was regarded theoretically as an opponent and in the other as a partner. It is concluded that the contention thatthe therapist must decide whether to be influential or cooperative arises from a logical confusion by failing to recognize that therapy cannot be anything other than cooperation.Originally published as part of a special issue on the power metaphor guestedited by Klaus G. Deissler inZeitschrift fur systemische Therapie (1986),4, 253–257. Translated by S. Awodey. 相似文献

Pigeons were trained to acquire a new four-response position sequence each day by pecking three response keys in a predetermined order. The key color varied after each correct response prior to food delivery. Acute administration of Γ9-tetrahydrocannabinol (Δ9-THC) up to a dose that completely eliminated responding, had no effect on total acquisition errors, or on within session patterns of error elimination. Chronic administration of Δ9-THC (3–10 mg/kg/day), either before or after the session for 4–7 weeks, also did not affect these error measures, although rates of responding were markedly suppressed and at times no responding occurred Discontinuation of Δ9-THC administration for periods of 4–6 weeks also was without effect on errors. These experiments suggest that neither acute nor chronic Δ9-THC produce specific effects on the repeated acquisition of serial position responses in pigeons. 相似文献
