This study evaluates the behavioral consequences of childhood abuse (sexual, physical, or both), with particular focus on prevalence of posttraumatic stress disorder (PTSD). Three abuse type groups and nonabused controls were contrasted on behavioral rating scales and on structured psychiatric interview data. The participants (109 abused children and 16 normal control children) were recruited from Arkansas Children’s Hospital and local agencies for abused children. As expected, proportionately more females than males were sexually abused. Overall, males were rated as more disturbed than females. Type of abuse did not consistently influence behavioral ratings. Externalizing scores were significantly higher than internalizing scores in all abused groups. PTSD was diagnosed in 50% of the abused children, with a higher rate for boys who had been sexually abused as opposed to physically abused only (58% versus 13%). The most frequent comorbid condition with PTSD was Separation Anxiety. Sexually abused boys were hospitalized for psychiatric treatment at a higher rate than were other abused children.  相似文献

In four experiments, we explored the heading and path information available to observers as we simulated their locomotion through a cluttered environment while they fixated an object off to the side. Previously, we presented a theory about the information available and used in such situations. For such a theory to be valid, one must be sure of eye position, but we had been unable to monitor gaze systematically; in Experiment 1, we monitored eye position and found performance best when observers fixated the designated object at the center of the display. In Experiment 2, when we masked portions of the display, we found that performance generally matched the amount of display visible when scaled to retinal sensitivity. In Experiments 3 and 4, we then explored the metric of information about heading (nominal vs. absolute) available and found good nominal information but increasingly poor and biased absolute information as observers looked farther from the aimpoint. Part of the cause for this appears to be that some observers perceive that they have traversed a curved path even when taking a linear one. In all cases, we compared our results with those in the literature.  相似文献

This article considers the Rorschach and its prospects for the next century in the context of two broad issues in psychology, as well as some test specific challenges confronting those interested in the Rorschach and its applications. The broad issues are the matters of personality as a topic of study in psychology, and the relation of findings about personality to treatment planning. The specific issues concern the definition of the Rorschach, research about the test stimuli, and the expansion of information concerning the interpretive usefulness of some structural variables that are poorly conceptualized or for which interpretation may be overly generalized. Some recommendations concerning collaborative research efforts are also offered.  相似文献

The threat of job discrimination causes many gay men and lesbians to keep their sexual orientation secret at work. This study investigates the relationships between extent of communication about sexual orientation and critical work attitudes. We hypothesize that "closeted" gay workers will experience more negative work attitudes than will either "openly" gay or heterosexual workers. The sample consisted of 900 lesbian, gay, and heterosexual workers identified from the mailing list of a civil rights group focused on homosexual rights. The hypothesis is supported for affective organizational commitment, job satisfaction, belief in support of top management, role ambiguity, role conflict, and conflict between work and home issues, but not for continuance commitment. Although causal relationships are not specified, we conclude that work attitude levels of gay and lesbian workers are predicted in part by the amount of communication about their sexual orientation in which these workers engage.  相似文献

Parenting practices have been previously linked to childhood symptomatology. However, little consideration has been given to the potential effect of individual differences within the child on this relation. The current study assessed the moderating effects of children's activity level and fear on relations between parenting practices and childhood aggression and depressive symptoms using a sample of 64 fourth-, and fifth-grade boys. The findings showed that poorly monitored active boys and fearful boys who were exposed to harsh discipline exhibited high levels of aggression. Boys characterized by high fear who were exposed to harsh discipline or whose parents were extremely overinvolved showed elevated levels of depressive symptoms. These findings suggest that integrating children's individual differences with parenting models enhances our understanding of the etiology of childhood symptomatology. The intervention implications of such an integration are discussed.  相似文献
