The psychiatric sequelae of loss of a family member to suicide were evaluated in parents and siblings of adolescent suicide victims and controls, who were followed up to 3 years after the suicide. Siblings did not show an increased risk for the development of depression, posttraumatic stress disorder (PTSD), or other conditions over the course of follow-up, despite showing a prolonged elevated level of grief symptomatology. Mothers showed an increased rate of recurrence of depression over follow-up, whereas fathers did not show an increased incidence of disorder compared to fathers of controls. The interrelationship of bereavement and depression for siblings, parents, and others exposed to suicide is discussed. 相似文献

This article describes Cupid, a program that performs computations with univariate probability distributions. Cupid can be useful in stochastic modeling and simulation, hypothesis testing, and examination of statistical procedures. The program runs on IBM-PC compatibles under the DOS operating system, and it is free for educational and noncommercial use. 相似文献

Individuals engaged in a location task where the relevancy status [relevant (stimulus) vs irrelevant (distractor) information] of these locations was reversed from one trial (prime) to the next (probe). The results produced by these reversals (Distractor-to-Stimulus and Stimulus-to-Distractor) indicated that both stimulus and distractor items are given relevancy status labels which participate in the future processing at the labeled locations. These findings support the view that selective processing involves both `facilitatory' and `inhibitory' components. Further, unlike identity tasks, the data indicated that neither the formation nor the subsequent use of these `location' labels (stimulus or distractor) is related to the presence of a response conflict.PsycINFO classification: 2330; 2340 相似文献

Fixed-interval schedules of intravenous cocaine presentation were examined as a function of injection dose (0.32 to 0.64 mg/kg) and interval duration (200 to 400 sec) in two rats. Cocaine was found to exert a dose-related temporal control over the initiation of responding that was unaffected by the fixed-interval contingency. Fixed-interval pause duration was linearly related to injection dose and was the same duration as the interresponse time found on continuous reinforcement schedules of cocaine presentation. The fixed-interval pause remained constant with changes in interval duration. Characteristic fixed-interval patterns of responding were observed. However, overall response rates were inversely related to injection dose and directly related to interval duration. Running response rates varied unsystematically with both variables. These findings are at variance with results typically found in studies of fixed-interval food and electric shock presentation. 相似文献

Between 65 and 75 % of juvenile-justice involved (JJI) youth present with at least one behavioral health disorder. Many communities have developed diversion programs that provide behavioral health services to JJI youth, often in lieu of detention. A key component of successful diversion programming is accurate screening and assessment. The Ohio Scales, a validated instrument designed to track service effectiveness in clinical samples of youth, are now being used with juvenile justice populations. The purpose of this study is to validate the Ohio Scales in a JJI youth population (N = 2246). The population (ages 12–18) is derived from Ohio’s Behavioral Health Juvenile Justice Initiative, a diversion program for JJI youth with behavioral health issues. We conducted Confirmatory Factor Analyses (CFA) on all forms of the Ohio Scales (parent, youth and worker) to measure fit for one factor, four factor and four factor second order solutions. We also conducted an Exploratory Factor Analysis (EFA) on the Problem Severity factor in the youth form to determine the number of appropriate sub-factors. The EFA indicated that the Problem Severity factor should be broken into three hypothesized sub-factors: Externalizing, Internalizing and Delinquency. The CFA confirmed this solution. CFA results indicated the four factor second order solution fits superior to the other two solutions. Using the Ohio Scales Problem Severity measure as a three sub-factor measure may increase clinical applicability by allowing a clinician to specifically measure and target externalizing or internalizing issues during treatment. 相似文献

A total of 1,687 course evaluation questionnaires, submitted by students attending undergraduate programmes in theology, indicated some significant age-related differences in responses. Overall, mature students displayed a higher level of appreciation for the lecturers, although they tended to be more critical when opportunities were not given for an interactive learning experience. 相似文献

Meet the Sorbs. They are a Slavic people in Germany who number around sixty thousand. They are not mistreated or oppressed by the German government. They live in two German states, but they are interspersed with other Germans. Do the Sorbs deserve special, group rights to help maintain their culture? The recent arguments of many theorists suggest that they do. Iris Marion Young has recently argued that all marginalized groups should have group rights. Avishai Margalit and Moshe Halbertal maintain that all cultural groups have certain rights. Will Kymlicka suggests that all ‘societal cultures’ have group rights, which might include the Sorbs. 相似文献

Death-related thoughts produce different effects on thought and behavior when they are in current focal attention and when they are on the fringes of consciousness. When such thoughts are conscious, people attempt to either remove them from consciousness or push death into the distant future by distorting their beliefs to logically imply that they have many remaining years to live. When such thoughts are highly accessible but outside current focal attention, people increase efforts to view themselves as persons of value living in a meaningful universe. In this way, awareness of the inevitability of death produces diverse effects on human thought and behavior that bear little obvious resemblance to the problem of death. 相似文献
