This paper proposes methods for modelling risk and uncertainty with the analytic hierarchy process (AHP). We start by showing why benefit/risk ratios, as described in previous literature, might be an improper modelling approach. We then introduce prototypical case studies where risk plays a role in multicriteria decision making. These cases demonstrate how the AHP can be used to derive relative probabilities, multiple criteria outcome measures, risk criteria, and risk adjustment factors.

Cognitive and Emotion‐Regulatory Mediators of the Relationship Between Behavioral Approach System Sensitivity and Nonsuicidal Self‐Injury Frequency 下载免费PDF全文
Taylor A. Burke BA Jonathan P. Stange MA Jessica L. Hamilton MA Jonah N. Cohen MA Jared O'Garro‐Moore MA Issar Daryanani BA Lyn Y. Abramson PhD Lauren B. Alloy PhD 《Suicide & life-threatening behavior》2015,45(4):495-504
Nonsuicidal self‐injury (NSSI) is highly prevalent among late adolescents and predicts the onset of suicidal ideation and behavior. Although research has established an association between the behavioral approach system (BAS) and NSSI, less research has explored mechanisms underlying this relationship. The authors examined negative and positive emotion regulation patterns, as well as the BAS‐relevant cognitive style of self‐criticism, as potential mechanisms through which a hypersensitive BAS might be related to NSSI frequency. Late adolescents (N = 177) with high and moderate BAS levels completed measures of self‐criticism, positive emotion regulation, brooding, and both lifetime and last‐year frequency of NSSI. Results indicated that self‐criticism and positive emotion dampening independently mediated the relationship between BAS and last‐year frequency of NSSI. Self‐criticism also mediated the relationship between BAS and lifetime frequency of NSSI. Results suggest that cognitive and emotion‐regulatory styles may help to explain why high BAS individuals are likely to engage in NSSI. 相似文献

Research suggests that both the military and veteran and the lesbian, gay, bisexual, and transgender (LGBT) populations may be at increased risk for suicide. A literature review was conducted to identify research related to suicide risk in the LGBT military and veteran populations. Despite the paucity of research directly addressing this issue, themes are discussed evident in the literature on LGBT identity and suicide risk as well as LGBT military service members and veterans. Factors such as social support and victimization appear to be particularly relevant. Suggestions are made with respect to future research that is needed on this very important and timely topic. 相似文献

The purpose of this study was to determine which aspects of insomnia best predict suicidal ideation (SI). Participants were grouped according to whether they complained of insomnia and whether their sleep would be characterized as poor or good by applying quantitative criteria for insomnia to their sleep diary data. Analyses revealed that insomnia complaint was more strongly associated with SI than was poor sleep. These findings suggest that patients who complain of insomnia, regardless of the presence or absence of poor sleep, may be at greater risk for suicide than those who are content with their sleep. 相似文献

Childhood physical abuse is a major risk factor for suicide attempt, but factors that moderate this risk remain largely unexamined. Moderated mediation analysis was used with 186 adolescents who responded to the Profiles of Student Life: Attitudes and Behavior survey. Physical abuse increased risk directly and indirectly through reduced self‐esteem. Involvement in youth programs moderated the direct effect. Community service moderated the indirect effect. Results indicate 2 hours per week of involvement in youth programs and 2 hours per week of community service mitigated suicide attempt risk associated with abuse. Providing avenues for youth experiencing abuse to increase their community service and involvement is recommended. 相似文献

Nonsuicidal self‐injury is especially common in adolescents and young adults. Self‐injury may be related to shame or guilt—two moral emotions—as these differentially predict other maladaptive behaviors. Using a college sample, we examined not only how shame‐proneness, guilt‐proneness, and internalizing emotional tendencies related to self‐injury, but also whether these moral emotions moderate the relation between internalizing tendencies and self‐injury. High shame‐proneness was associated with higher frequencies of self‐injury. High guilt‐proneness was associated with less self‐injury, although this effect was mitigated at higher levels of internalizing tendencies. These results suggest shame‐proneness is a risk factor for self‐injury, while guilt‐proneness is protective. 相似文献

The correlates of nonsuicidal self‐injury (NSSI) among Asian and Caucasian university students; differences in the rates, frequency, forms, severity, and emotional contexts of NSSI among self‐injuring students; and whether Asian students who are highly oriented toward Asian culture differed from those less oriented toward Asian culture in NSSI characteristics were investigated. University students (N = 931), including 360 Caucasian students (n = 95, 26.4%, with a history of ≥ 1 episode of NSSI) and 571 Asian students (n = 107, 18.7%, with a history of NSSI), completed questionnaires assessing NSSI, acculturation, and putative risk factors for NSSI. Caucasian students were more likely to report NSSI, particularly cutting behavior, self‐injured with greater frequency and versatility, and reported greater increases in positively valenced, high arousal emotions following NSSI, compared to Asian students. Among Asian students, obsessive–compulsive symptoms, experiential avoidance, and anger suppression increased the likelihood of reporting a history of NSSI. Among Caucasian students, lack of emotional clarity and anger suppression increased likelihood of NSSI. Finally, some tentative findings suggested potentially important differences in rates and frequency of NSSI among Asian students who were highly oriented toward Asian culture compared with those less oriented toward Asian culture. 相似文献

Risk for suicide is elevated among older men. We examined whether value placed on autonomy amplifies the relation between depressive symptoms and suicide risk differently for older men and women. Participants were 98 community‐dwelling older adults, M age 73.6 (SD = 8.6), 65.1% female, 93.1% White. Questionnaires measured suicide risk (SBQ‐R), depressive symptoms (CESD), and value placed on autonomy (PSI‐II autonomy). Among men, depressive symptoms were associated with suicide risk only when PSI‐II autonomy was elevated. Among women, greater depressive symptoms were associated with suicide risk at all levels of PSI‐II autonomy. Further research on attitudes toward autonomy is warranted. 相似文献

Nonsuicidal Self‐Injury Is Predictive of Suicide Attempts Among Individuals with Mood Disorders 下载免费PDF全文

Nonsuicidal self‐injury (NSSI) prior to age 18 was evaluated as a risk factor for adulthood suicide attempt (SA). Archival data from 222 mood‐disordered participants were analyzed using multivariate Cox proportional hazards analysis. Participants with a youth SA were excluded. The hazards of SA among adult participants with a history of youth NSSI were twice than those of mood‐disordered participants without youth NSSI (hazard ratio = 2.00, 95% confidence interval = 1.16–3.44, p = .01). Moreover, participants who had both youth and adult NSSI attempted suicide significantly earlier than participants who began NSSI as an adult. Youth NSSI is associated with persistent, elevated SA risk in adulthood. 相似文献
