Findings concerning the long‐term effects of the Family Bereavement Program (FBP) to reduce suicide ideation and/or attempts of parentally bereaved children and adolescents are presented. Parental death is a significant risk factor for suicide among offspring (Guldin et al., 2015). This study is a long‐term follow‐up of 244 children and adolescents who had participated in a randomized trial of the FBP, examining the intervention effects on suicide ideation and/or attempts as assessed through multiple sources. Results indicate a significant effect of the FBP to reduce suicide ideation and/or attempts at the 6‐ and 15‐year follow‐up evaluation. The findings support the potential benefits of further research on “upstream” suicide prevention.  相似文献

We evaluated rates of automatically reinforced stereotypy and item engagement for 2 children with autism under multiple and chained schedules in a multielement design. Each schedule included components during which stereotypy was blocked (S–) or allowed (S+), and we used colored cards as schedule‐correlated stimuli. We report rates of stereotypy and item engagement during S– and S+ components, as well as the percentage of component time that elapsed before the first instances of stereotypy and item engagement. We observed less stereotypy and more consistent item engagement during chained‐schedule sessions, and stimulus control of stereotypy and item engagement was established with the chained schedule. A subsequent concurrent‐chains analysis revealed participant preference for the chained schedule. These results highlight the importance of contingent access to stereotypy when therapists attempt to gain stimulus control of stereotypy and increase functional item engagement.  相似文献

Two major events are generally cited as indicative of the new hostile Counter-Reformation attitude of the Papacy toward the Jews and consequently as causing a deterioration of the situation of the Jews throughout the Italian peninsula. The first is the papal bull Cum Nimis Absurdum issued in 1555 by Paul IV, the zealous former Cardinal Caraffa, only months after he assumed the papal throne, while the second is the burning at the stake in 1556 of the former New Christians who had reverted to Judaism in Ancona. While not minimizing the importance of Cum Nimis Absurdum and the action against the former New Christians in Ancona, it may nevertheless be instructive to step back and reconsider their impact on the Jews of the Italian peninsula and clarify whether they really represented a major peninsula-wide turning point.  相似文献

Mental health literacy is the knowledge and beliefs about mental disorders that aid their recognition, management, or prevention and is considered to be an important determinant of help‐seeking. This has relevance in suicide prevention, as depression, the clinical condition most frequently associated with suicidality, has been the target of community and professional education programs designed to enhance mental health literacy. In this study, whether such programs have influenced help‐seeking attitudes and behavior in those who are depressed and suicidal was considered. The results indicate that despite intensive community education programs over the last two decades, there has been little change in those who are depressed and suicidal in terms of their attitudes toward treatment seeking and, more importantly, their treatment‐seeking behavior. These results draw into question the value of current community education programs for those most vulnerable to suicidal behavior.  相似文献

Researchers tested the hypothesis that the negative impact of recent life events would moderate the relationship between intrinsic religiosity and death ideation in older adults. Participants (n = 272) completed assessments of death ideation, intrinsic religiosity, and negative impact of recent life events. We confirmed the presence of concurrent moderation and found that older adults with greater negative impact of recent life events and high intrinsic religiosity reported greater death ideation. These relatively surprising findings may be due to reduced fear of death in intrinsically religious older adults, an explanation consistent with previous research.  相似文献
