Suicide attempts constitute a serious clinical problem. People who have attempted suicide are at an elevated risk for additional suicide attempts, but there is limited evidence regarding the predictors of suicidality of suicide attempters following case management services. In the present study the indicators of suicidality after case management were examined. A total of 1,056 subjects who had recently attempted suicide were recruited from January 1, 2011, to June 30, 2011. The suicide prevention center of Kaohsiung City in Taiwan provided case management services and followed up on suicide attempt cases for 6 months. The salient factors for repeat suicide attempts were estimated using a logistic regression analysis. The results showed that multiple factors, including a “willingness to receive mental health services during a crisis,” “social support,” “a history of mental disorders,” and “a history of suicide,” could predict repeat suicide attempts with hazard ratios (0.58, 0.54, 3.84, 1.51) and 95% confidence interval (0.39–0.86, 0.36–0.83, 2.41–6.10, 1.03–2.21). The four factors mentioned above were the most accurate predictors of subsequent suicidality when case management services were utilized after 6 months of follow‐up. The findings of our study could help clarify future strategies for suicide prevention. 相似文献

Despite substantial evidence indicating a close link between action production and perception in early child development, less is known about how action experience shapes the processes of perceiving and anticipating others’ actions. Here, we developed a novel approach to capture functional connectivity specific to certain brain areas to investigate how action experience changes the networks involved in action perception and anticipation. Nine- and-12-month-old infants observed familiar (grasping) and novel (tool-use) actions while their brain activity was measured using EEG. Infants’ motor competence of both actions was assessed. A link between action experience and connectivity patterns was found, particularly during the anticipation period. During action anticipation, greater motor competence in grasping predicted greater functional connectivity between visual (occipital alpha) and motor (central alpha) regions relative to global levels of whole-brain EEG connectivity. Furthermore, visual and motor regions tended to be more coordinated in response to familiar versus novel actions and for older than younger participants. Critically, these effects were not found in the control networks (frontal-central; frontal-occipital; parietal-central; parietal-occipital), suggesting a unique role of visual-motor networks on the link between motor skills and action encoding.
Highlights
- Infants’ motor development predicted functional connectivity patterns during action anticipation.
- Faster graspers, and older infants, showed a stronger ratio of visual-motor neural coherence.
- Overall whole-brain connectivity was modulated by age and familiarity with the actions.
- Measuring inter-site relative to whole-brain connectivity can capture specific brain-behavior links.
- Measures of phase-based connectivity over time are sensitive to anticipatory action.

This study investigated the time course of belief change from univalent versus mixed‐valence messages, both while the message was being received and after receipt while it was being considered. Hypotheses about the temporal patterns of belief change were tested with belief trajectories from S. E. McGreevy (1996) , valid N= 78, with an average number of time points per person = 5,267 (126.41 seconds) for the message‐receipt phase and 2,467 (59.22 seconds) for the postmessage phase. Results showed that while receiving a message, beliefs changed according to the value and the order of presentation of information in the message. A greater number of positive belief changes were generated in response to a positive univalent message than to a mixed‐valence message. In the postmessage phase, a greater oscillatory pattern of belief change was found for a mixed‐valence message than for a univalent message. Theoretical and methodological implications of these findings are discussed. 相似文献

Multivariate dynamic relationships among suicide attempts, anxiety and/or depressive symptoms, hope, and help‐seeking were examined across time in Native Hawaiian and non‐Hawaiian adolescents, using data from a 5‐year longitudinal cohort study (N = 7,317). The rate of suicide attempts decreased over time, but this reduction was significantly less among Native Hawaiian youth than their non‐Hawaiian peers. There were also significant differences between groups in hope and help‐seeking, with Native Hawaiian youth increasing help‐seeking and decreasing hope to a greater degree. Youth‐centered, cultural approaches to suicide prevention are essential in enhancing well‐being in indigenous communities. 相似文献

A 3‐year nationwide population‐based data set was used to explore methods of suicide (violent vs. nonviolent) and possible contributing factors among cancer patients in Taiwan. A total of 1,065 cancer inpatients who committed suicide were included as our study sample. The regression shows that those who had genitourinary cancer were 0.55 times (p = 0.047) less likely to use violent methods to commit suicide than those who had respiratory cancer. Among those who committed suicide out of town, the odds of using violent methods were 1.39 (p = 0.015) of their counterparts who had committed suicide in their hometowns. Those who had income between NT$15,841~NT$25,000 were 0.70 (p = 0.042) times less likely to use violent methods to commit suicide than those who had no income. 相似文献
