There is consistent evidence that impulsivity is linked to tobacco consumption and to symptomatology in schizophrenia. In the current study, we propose a new integrative model of the relationship between impulsivity, psychopathological symptoms, and tobacco status in patients with paranoid schizophrenia. We investigated 33 paranoid schizophrenia patients and 37 healthy controls using a battery of psychopathological scales included the Structured Clinical Interview for DSM-IV (SCID), the five-factor model of the Positive and Negative Symptom Scale (PANSS), the Barratt Impulsiveness Scale (BIS-10), and the UPPS Impulsive Behavior scale (UPPS). Step-wise regression analysis revealed that positive factor of the PANSS and tobacco status contributed positively and significantly to the explained variance of impulsivity. In addition, non-planning impulsivity and sensation-seeking emerged as significant predictors of tobacco status, while smoking predicted non-planning impulsivity and sensation-seeking. Our results suggest that the relationship between sensation-seeking and tobacco use is reciprocal and proposes a new integrative model of the relationship between impulsivity, positive symptoms and tobacco status in patients with paranoid schizophrenia. However, the exact mechanisms for these relationships deserve further investigation.  相似文献

A young Italian male was investigated for possession of illicit marijuana in Rome. In his house, police found 80 cannabis plants, the plants were different sizes and located in a room with ultraviolet light, naphthalene, as a grey-white powder, was also found in his house. The man indicated that he used it for cannabis cultivation.  相似文献

Research suggests that the safer students feel at school, the more likely they are to feel connected and able to focus on learning. Thus, measuring students’ experiences with a school safety officer (SSO) is essential to understand the connection between officer engagement and students’ safety. This study’s purpose was to evaluate a SSO scale among 1,065 adolescents. Results suggest the SSO scale displayed excellent internal consistency estimates, construct validity via factor analysis, convergent validity with the School Climate Measure, discriminant validity with key demographic variables, and known-groups validity among students who reported fighting at school. Positive perceptions of SSOs also significantly increased with frequency of contact. The SSO scale is a preliminarily valid measure, potentially useful in research, screenings, and/or evaluation efforts to improve student engagement with SSOs.  相似文献

The positive benefits to children of their fathers' involvement in their lives have been well documented in the social science literature. This article reviews related child welfare literature and argues that several important concepts informing father involvement research in the social sciences—the significance of the parents' relationship, the potentially dangerous behaviors of fathers, and emerging trends in low-income families—need to be incorporated into work on father involvement in the child welfare context, in order to maximize the effectiveness of involvement efforts as well as the potential benefits to children. Implications for child welfare practice include the need for intensive involvement efforts, attention to fathers' progress in treatment, services to strengthen parental relationships and improve coparenting, and expansion of service eligibility to all those who play parental roles in children's lives. Implications for research include the need for studies examining the different kinds of fathers in child welfare households, how parental dynamics influence child and parent outcomes, and the influence fathers' problems may have in moderating the effects of their involvement on children.  相似文献

The aim of the study is to examine the role of cognitive coping in a sample of 47 female victims of stalking. Stalking victims who blamed themselves more for the stalking report significantly higher symptoms of depression, anxiety, and posttraumatic stress disorder (PTSD). Respondents who ruminated more about the stalking experience, or respondents who explicitly emphasized the terror of the stalking to a higher extent, also report significantly higher symptom levels. Finally, respondents who thought more about what steps to take and how to handle the stalking report significantly higher symptom levels of depression, anxiety, and PTSD. This conclusion holds also after controlling for the severity of stalking. If the findings of the present study can be confirmed, this could possibly contribute to the help provided to victims of stalking.  相似文献

The presence of gunshot residues (GSRs) on arrested suspects can help the Court to form an opinion regarding the possibility of utilization of firearms by these suspects. Since the presence of a few particles can in some cases already have a strong indicative value, the GSR experts have to evaluate in their daily work the risk of a potential contamination of these suspects during their arrest. A few studies conducted on police officers and police facilities concluded that the risk of secondary transfer on arrested suspects is quite negligible. However, the case of special force units of the police should be taken into account, since these units can be assumed to be highly contaminated by GSR due to their intensive training. The aim of this study is to evaluate this possibility of particle transfer by performing simulations of arrests by special force police units, according to both low and high contamination scenarios. The results show that secondary transfers of GSR during these simulations are in most cases not negligible, even for the low contamination scenario. This is especially apparent on the vests of the target persons, with an average of 7 GSR particles (2 PbBaSb and 5 TiZn) found on the stubs used on these materials. Of course, the major contamination levels were observed in the case of the high contamination scenario, due to the use of highly contaminated gloves by the police officers during the arrests. Some recommendations are proposed to take into account this risk of contamination and to try to minimize it, or at least to better identify it.  相似文献
