Suicide risk is elevated in psychiatric patients following discharge from inpatient care. Despite this vulnerability, there has been limited research investigating suicide prevention protocols that take into account the unique system characteristics of this setting (e.g., short lengths of stay, crisis stabilization treatment model, multidisciplinary team coordination). Cognitive-behavioral therapy (CBT) has demonstrated efficacy for improving suicide risk in outpatients, but has not been validated with inpatients. The current study was a treatment development and pilot feasibility open trial that modified brief cognitive-behavioral therapy (BCBT) for an inpatient setting (BCBT-I). Key treatment modifications included administering up to 10 sessions (depending on patient length of stay), daily, and in a standardized order, with core crisis management skills introduced during the first three sessions. In addition, coordination with the inpatient treatment team was included in BCBT-I implementation. Six adult inpatients with a recent suicide attempt enrolled and completed an average of 4.67 BCBT-I sessions (SD = 1.36). The treatment was highly acceptable (Client Satisfaction Questionnaire total score M = 3.49, SD = 0.73). Pre- to posttreatment effect sizes demonstrated improvements in suicidal ideation (d = 0.97), depression (d = 1.33), and suicidal implicit associations (d = 1.28). All but one of the participants (83%) completed follow-up assessments 1-, 2-, and 3-months postdischarge. Over follow-up, two participants reported suicidal ideation (both without intent), and none reported suicide attempts, preparatory acts or behaviors, or nonsuicidal self-injury. This study provided preliminary evidence supporting the feasibility of CBT to treat suicidal inpatients. Future research is needed to validate BCBT-I in a larger, randomized controlled trial to determine whether BCBT-I reduces suicide risk beyond that afforded by inpatient treatment alone.  相似文献

Accurate analysis of data is vital to the validation of interventions. As such, there has been a recent increase in studies evaluating visual analysis training procedures. However, past investigations have not evaluated direct and indirect visual analysis training methods with matched instructional content that was systematically designed. Furthermore, training has rarely included assessment of generalization and maintenance of visual analysis skills. The purpose of the current dissertation study was to compare the effectiveness and efficiency of (a) computer‐based training, (b) lecture formats with and (c) without the opportunity to pause, and (d) a no‐training group to teach visual analysis of AB graphs to university students. To make these formats directly comparable, the instructional content was equated by ensuring information and examples were identical across the three training procedures. Eighty‐three students were randomly assigned to one of the four groups. Results showed that all three training formats produced increases in accurate responding compared to the no‐training group. Visual analysis skills generalized to novel graphs and maintained approximately 2 weeks following all trainings. These results suggest that structured approaches that are carefully designed to train visual analysis are effective and lead to gains that generalize and maintain in the absence of training.  相似文献

多时点结果跨期选择涉及两个及两个以上多个时点结果的权衡, 正日益成为跨期选择的研究重点。现有研究主要从两时点结果和序列结果两方面深入探讨了多时点结果跨期选择中的诸多决策效应, 包括:隐藏的零效应、象征效应、额外金额效应、前端金额效应以及序列效应, 并运用序列模型和权衡模型对上述决策效应进行阐释。未来还应深入探索同时涉及损益结果混合的多时点结果跨期选择, 运用决策过程追踪技术揭示决策效应的过程机制。  相似文献

本研究采用事件相关电位技术(ERPs)结合多源干扰任务(MSIT)范式来探讨特质自我控制个体的认知神经机制。考察了高、低自我控制者各26名在MSIT任务上的差异。结果:高自我控制者的反应时显著长于低自我控制者。在MSIT冲突条件下,高自我控制者的N2和P3(LPC)波幅比无冲突条件更大。结论:高自我控制者较低自我控制者处理冲突干扰更慢,需要的注意资源较多,激活前额叶中部脑区。  相似文献

People with multiple sclerosis (MS) can experience problems in interpreting others’ emotions from faces or voices. However, to date little is known about whether difficulties in emotion perception in MS are related to broader aspects of social functioning. Also, there are few studies reporting the effect of MS on more ecologically valid assessments of emotion perception using multimodal videos. The current study looks at (1) the effect of MS on perceiving emotions from faces, voices and multimodal videos; (2) the possible role of slowed processing and executive dysfunction in emotion perception problems in MS and (3) the relationship between emotion perception and broader social functioning in MS. 53 people with MS and 31 healthy controls completed tasks of emotion perception and cognition, and assessed their levels of social support and social participation. Participants with MS performed worse than demographically matched controls on all measures of emotion perception. Emotion perception performance was related to cognitive measures in those with MS. Also, significant associations were found between emotion perception difficulties in MS and poorer social function. In particular, people with MS who had poorer emotion perception also reported lower levels of social support from their friends, and regression analysis showed that this prediction was maintained even when disease severity and cognitive function were taken into account. These results show that problems with emotion perception in MS extend to more realistic tasks and may predict key aspects of social functioning.  相似文献

Quantitative models of resurgence (e.g., Behavioral Momentum Theory, Resurgence as Choice) suggest that resurgence is partly a function of the duration of extinction exposure, with longer histories of extinction producing less resurgence. This prediction is supported by some laboratory research and has been partially supported by clinical translations that did not isolate the effects of extinction exposure prior to testing for resurgence. The degree to which different histories of extinction impact the likelihood of treatment relapse in therapeutic applications of differential reinforcement is of great interest to the clinical community, including insurance carriers and other financial providers. In the present study, we isolated the effects of extinction history for severe destructive behavior across 6 participants referred for treatment services and examined resurgence of destructive behavior when alternative reinforcement terminated. Our within-subject evaluation showed no difference in the level of resurgence or persistence of destructive behavior following short and long exposures to differential reinforcement with extinction. We discuss our failure to replicate in relation to experimental-design considerations for investigating this and other relapse phenomena in future research with clinical populations.  相似文献

There is high variability in efficacy for interventions for youth with disruptive behavior problems (DBP). Despite evidence of the unique correlates and critical consequences of girls’ DBP, there is a dearth of research examining treatment efficacy for girls. This meta-analysis of 167 unique effect sizes from 29 studies (28,483 youth, 50% female; median age: 14) suggests that existing treatments have a medium positive effect on DBP (g = .33). For both boys and girls, the most effective interventions included (a) multimodal or group format, (b) cognitive skills or family systems interventions, and (c) length-intensive programs for (d) younger children. Boys demonstrated significantly greater treatment gains from group format interventions compared to girls, which is particularly important given that the group program format was the most prevalent format for boys and girls, with 14 studies involving 10,433 youth encompassing this category. This is the first meta-analysis to examine the effect of program characteristics in a sample of programs selected to be specifically inclusive of girls. Given that girls are underrepresented in intervention research on DBP, findings are discussed in terms of gender-responsive considerations and elucidating how key aspects of program structure can support more effective intervention outcomes for youth.  相似文献
