Suicidal behavior is frequent in patients with borderline personality disorder (BPD); at least three-quarters of these patients attempt suicide and approximately 10% eventually complete suicide. Borderline patients at greatest risk for suicidal behavior include those with prior attempts, comorbid major depressive disorder, or a substance use disorder. Comorbidity with major depression serves to increase both the number and seriousness of the suicide attempts. Hopelessness and impulsivity independently increase the risk of suicidal behavior, as does a turbulent early life and the presence of antisocial traits. In summary, because BPD is frequently complicated by suicidal behavior, clinicians must avoid the mistake of thinking that a pattern of repeated attempts indicates little desire to die. Clinicians have an important role in preventing suicide attempts and completed suicides by understanding the risk factors.  相似文献

Two studies investigated teachers' and principals' power styles as related to college students' retrospective ratings of satisfaction and peers' abusive behavior. One study also investigated retrospective self-perception as related to students' sensitivity to the occurrence of physical and psychological abuse in the school environment. Among the findings were positive correlations between subjects' perceptions that their typical elementary school teacher used referent, legitimate, or expert power styles and subjects' reported satisfaction with their elementary school experience. Small but statistically significant correlations were found suggesting that principals' power style was weakly associated with ratings of psychological abuse in elementary school and physical abuse in middle school. Also, students who rated themselves as intelligent, sensitive, attractive, and depressive had higher ratings of perceived psychological and physical abuse at school. It was concluded that parameters of leaders' power styles and subjects' vigilance might be useful for understanding school climates. Experimentally designed studies are required.  相似文献

Personality disorders at the crossroads   总被引:1,自引:0,他引:1  
Personality disorders are now at a crossroads with respect to theory, research, and conceptualization. In this article, we review relevant and current issues within the personality disorder field. After reviewing changes in the conception of personality disorders across the past half century (1952 to 2002), we focus on the issue of continuity versus discontinuity methodologies for assessing personality, interactionism, treatments, resolved and unresolved issues, and future directions. The issue of continuity versus discontinuity is a theme in this article. We conclude that the evidence is in favor of a reapprochment between a categorical classification system and a dimensional system and we also outline the difficulties in achieving this change.  相似文献

What are the best quantitative methods for studying cognitive decline? This question was investigated in a sample of 638 individuals aged 50 years and older from the Swedish Adoption/Twin Study of Aging. A battery of cognitive tests tapping multiple domains was administered to each individual from 2 to 7 times over a span of 10 years. Four methods of operationalizing cognitive decline were compared: change scores, a criterion-based method, least squares, and random effects regression (RER). The RER results were most consistent with a significant decline across measures and differences between demented and nondemented individuals. Predicted slopes from the RER model also showed the strongest interrelationships within and across cognitive domains as indicated by factor analysis results and stronger associations with demographic, health, and psychosocial predictors.  相似文献

The role of regulation as a mediator of the relations between maternal emotional expressivity and children's adjustment and social competence was examined when children (N = 208) were 4.5 to just 8 years old (Time 1, T1) and 2 years later (Time 2, T2). At T2, as at T1, regulation mediated the relation between positive maternal emotional expressivity and children's functioning. When T1 relations and the stability of variables over time were controlled for in a structural equation model, T2 relations generally were nonsignificant, although parents' dominant negative expressivity predicted high regulation. In contrast, in regressions, the findings for parent positive expressivity, but not negative expressivity, held at T2 when T1 variables were controlled. Thus, relations for negative expressivity, but not positive expressivity, changed with age.  相似文献

The relations of children's nonsocial behavior to their emotionality, regulation, and social functioning were examined in a short-term longitudinal study. Parents (primarily mothers) and teachers rated children's effortful regulation, emotionality, asocial behaviors, problem behaviors, and social acceptance, and children's nonsocial play behaviors were observed for two semesters. Peers also rated likability. Children's observed reticent activities were related to adults' ratings of high regulation, low externalizing problems, and high asocial behavior, as well as to low anger and low positive emotion. On the other hand, solitary play was associated with low positive emotion and low regulation over time and with high asocial behavior and high peer exclusion. Peer rejection mediated the relation of internalizing emotions (anxiety, low positive emotion) and regulation to solitary play later in the school year, and asocial play mediated the relation of internalizing emotions to both solitary and reticent play behavior.  相似文献

This study evaluated the extent to which first-grade class size predicted child outcomes and observed classroom processes for 651 children (in separate classrooms). Analyses examined observed child-adult ratios and teacher-reported class sizes. Smaller classrooms showed higher quality instructional and emotional support, although children were somewhat less likely to be engaged. Teachers in smaller classes rated typical children in those classes as more socially skilled and as showing less externalizing behavior and reported more closeness toward them. Children in smaller classes performed better on literacy skills. Larger classrooms showed more group activities directed by the teacher, teachers and children interacted more often, and children were more often engaged. Lower class sizes were not of more benefit (or harm) as a function of the child's family income. First-grade class size in the range typical of present-day classrooms in the United States predicts classroom social and instructional processes as well as relative changes in social and literacy outcomes from kindergarten to first grade.  相似文献
