We investigated the psychometric validity and reliability of the Suicide Status Form‐II (SSF‐II) developed by Jobes, Jacoby, Cimbolic, and Hustead (1997) . Participants were 149 psychiatric inpatients (108 suicidal; 41 nonsuicidal) at the Mayo Clinic. Each participant completed assessment measures within 24 hours of admission and 48–72 hours later. Factor analyses of the SSF core assessment produced a robust two‐factor solution reflecting chronic and acute response styles. The SSF core assessment had good to excellent convergent and criterion validity; pre‐post SSF ratings also demonstrated moderate test‐retest reliability. The results replicated previous research and show that the SSF‐II is psychometrically sound with a high‐risk suicidal inpatient sample.  相似文献

Evidence for shared heritable influences across domains of substance use suggests that some genetic variants influence broad risk for externalizing behaviors. Theories of externalizing psychopathology also suggest that genetic liability for substance use manifests as temperamental risk factors, particularly those related to behavioral disinhibition, during adolescence. The cholinergic muscarinic receptor 2 gene (CHRM2) is a promising candidate for studying genetic influences on broad-based risk for externalizing traits. This study examined a candidate CHRM2 polymorphism (rs1455858) in relation to substance use and personality measures of disinhibition in a sample of high-risk adolescents (n?=?124). Bivariate analyses and structural equation modeling (SEM) evaluated associations of rs1455858 with measures of drug involvement (alcohol, tobacco and marijuana) and disinhibition (indexed by impulsivity and sensation seeking scores). Bivariate analyses showed significant associations of CHRM2 with several behavioral phenotypes. In SEM analyses CHRM2 related significantly to latent measures of substance use and disinhibition; additionally, disinhibition mediated the association of CHRM2 with substance use. These results suggest that CHRM2 variants are potentially relevant for adolescent substance use and that temperamental risk factors could contribute to these associations.  相似文献

Parent-referred 2- and 3-year-olds and controls, participating in a longitudinal study of hyperactivity and related behavior problems, were observed with their mothers during play at an initial assessment and a 1-year follow-up. Mothers of problem children provided more redirection initially and made more negative control statements at follow-up than mothers of controls; problem youngsters tended to play more aggressively. Sex differences were prominent. Mothers of boys, regardless of referral status, were more directive at the initial assessment; their sons were less cooperative and somewhat more aggressive in their play. Maternal involvement in play decreased over time, possibly as a response to developmental changes in children's play. Group by time interactions indicated that mothers of control children provided fewer negative control statements at follow-up relative to mothers of problem children and to their own levels at the first assessment; mothers of problem youngsters redirected their children less than they had initially. Mothers of boys were also less directive at follow-up relative to their initial levels. Situational and developmental factors are discussed briefly.  相似文献

This piece analyzes the tensions between racial liberalism and erotic representations in West German homosexual-oriented magazines between 1949 and 1974. Relying primarily on publications such as Der Kreis, Die Insel/Der Weg, Amigo, and Du & Ich, this paper argues that as white West German homosexual men made a case for the end of legal discrimination and for social acceptance, they often constructed their arguments and identity as a persecuted minority in relation to the struggles and imagined experiences of colonized men and racial minorities. At the same time, however, many homosexual men still maintained a set of assumptions about racial difference that exoticized and essentialized men of color, assumptions that are particularly apparent in the erotic representations (both visual and literary) of men of color that appeared in these magazines. I further argue that, although historians of homosexuality in West Germany have traditionally viewed 1969 as a break, due to the radical changes in gay life that followed the 1969 reform of the anti-sodomy statute, the tensions between racial liberalism and exoticization continued well into the 1970s and in a remarkably similar published format. The contradictions within these magazines add to the growing literature on both homosexuality and race in postwar West Germany. Through the close examination of a medium that was crucial to the formation of homosexual communities and the development reformist politics, we can more fully understand the complexities and tensions on which minority politics were built in the wake of fascism.  相似文献

College students(n = 162) completed measures of death anxiety and sexual risk-taking, with a thought listing procedure in-between. Those who completed the death anxiety measure first (Death Salient condition) reportedgreater willingness to engage in high-risk sexual behavior than the Non-Death Salient group. This result was consistent with the hypothesis that evoking death anxiety would produce denial-based defensive activity. Also, Death Salient participants reporting more death thoughts were lower on risk-taking, as predicted. Interestingly, Death Salient participants reporting stressful thoughts about issues unrelated to personal mortality (displacement) were also less willing to engage in high-risk sexual behavior. The results are discussed in relation to a new, avowal-based model of the process of psychological defense.  相似文献

Williams Syndrome (WS) is marked by a relative strength in verbal cognition coupled with a serious impairment in non-verbal cognition. A strong deficit in numerical cognition has been anecdotally reported in this disorder; however, its nature has not been systematically investigated. Here, we tested 14 children with WS (mean age=7 years 2 months), 14 typically developing controls individually matched on visuo-spatial ability (mean age=3 years 5 months) as well as a larger group of typically developing controls (mean age=3 years 4 months) on two tasks to assess their understanding that counting determines the exact quantity of sets (cardinality principle). The understanding of the cardinality principle in children with WS is extremely delayed and only at the level predicted by their visuo-spatial MA. In this clinical group, only language accounted for a significant amount of the variance in cardinality understanding, whereas in the normal comparison group only visuo-spatial competence predicted the variance. The present findings suggest that visuo-spatial ability plays a greater role than language ability in the actual development of cardinality understanding in typically developing children, whereas the opposite obtains for the clinical group.  相似文献

Student prejudice against gay male and lesbian lecturers   总被引:1,自引:0,他引:1  
The authors examined whether gay men and lesbians are evaluated more negatively than individuals of unspecified sexual orientation when attributional ambiguity surrounds evaluations and whether they are evaluated similarly to unspecified others when no attributional ambiguity is present. One male and one female lecturer delivered either a strong or a weak lecture to students who either (a) believed that the lecturer was a gay man or a lesbian or (b) did not receive sexual orientation information. Contrary to predictions, the quality of the lecture did not influence the ratings of known gay male and lesbian lecturers, although lecture quality strongly influenced ratings of lecturers whose sexual orientation was unspecified. After strong lectures, participants rated known gay male and lesbian lecturers more negatively than they did lecturers whose sexual orientation was unspecified. After weak lectures, participants rated known gay male and lesbian lecturers more positively than they did the others. The authors discussed the possibility that students might moderate their ratings to avoid discriminating against gay and lesbian lecturers.  相似文献
