This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004–2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal‐probability sample of 9,893 person‐months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [β] = ?.197 to ?.521; p < .01) and MTH (β = ?.024 to ?.064; p < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (β = ?.164 to ?.417; p < .05) and MTH continued to be associated with suicide attempt (β = ?.015; p = .046) and ideation (β = ?.014; p = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk. 相似文献

Debate continues about the accuracy of military suicide reporting due to concerns that some suicides may be classified as accidents to minimize stigma and ensure survivor benefits. We systematically reviewed records for 998 active duty Army deaths (510 suicides; 488 accident, homicide, and undetermined deaths; 2005‐2009) and, using research criteria, reclassified 8.2% of the nonsuicide cases to definite suicide (1), suicide probable (4), or suicide possible (35). The reclassification rate to definite suicide was only 0.2% (1/488). This low rate suggests that flagrant misclassification of Army deaths is uncommon and surveillance reports likely reflect the “true” population of Army suicides. 相似文献

Humans are motivated to connect with others and are sensitive to social exclusion—intentionally leaving out others. This ability to detect social exclusion is suggested to be evolutionarily adaptive, biologically hardwired, and an important feature of social-cognitive development. Yet it is unclear when children start to independently detect social exclusion. Previous developmental research on social exclusion has focused on children older than 4 years of age, but recent infancy research has suggested younger children may be able to process complex social interactions such as social exclusion. The present study is the first to examine whether 2- to 3-year-old children detect social exclusion and if they prefer to affiliate with individuals who have been excluded over individuals who exclude others. Across 2 experiments, 2- and 3-year-old children (N = 140) viewed exclusive group interactions, in which 2 agents unjustly excluded 1 agent, and children were asked to choose whether they preferred to play with an excluded agent or an exclusive agent. Three-year-old children consistently preferred to play with the excluded agent, whereas 2-year-old children showed no preference. Three-year-old children did not show a preference among agents engaged in inclusive interactions and did not prefer an agent who refused to engage with a group, showing that 3-year-old children distinguish unjust exclusion from other types of interactions. Together, these findings suggest 3-year-old children detect social exclusion and are motivated to affiliate with unjustly excluded agents over those who exclude others, whereas these capacities are still developing in 2-year-old children. 相似文献

Extended redundancy analysis (ERA) is used to reduce multiple sets of predictors to a smaller number of components and examine the effects of these components on a response variable. In various social and behavioural studies, auxiliary covariates (e.g., gender, ethnicity) can often lead to heterogeneous subgroups of observations, each of which involves distinctive relationships between predictor and response variables. ERA is currently unable to consider such covariate-dependent heterogeneity to examine whether the model parameters vary across subgroups differentiated by covariates. To address this issue, we combine ERA with model-based recursive partitioning in a single framework. This combined method, MOB-ERA, aims to partition observations into heterogeneous subgroups recursively based on a set of covariates while fitting a specified ERA model to data. Upon the completion of the partitioning procedure, one can easily examine the difference in the estimated ERA parameters across covariate-dependent subgroups. Moreover, it produces a tree diagram that aids in visualizing a hierarchy of partitioning covariates, as well as interpreting their interactions. In the analysis of public data concerning nicotine dependence among US adults, the method uncovered heterogeneous subgroups characterized by several sociodemographic covariates, each of which yielded different directional relationships between three predictor sets and nicotine dependence. 相似文献

Although structural priming has been considered to be an independent cognitive process, recent evidence suggests that structural priming is modulated by sociocognitive factors such as social perception; speakers are more likely to mimic the sentence structure of a socially desirable interlocutor than the structure of a less desirable interlocutor. This study aims to further address the role of sociocognitive factors in language use by investigating how individual differences in social perception and tendency to align with others (i.e., social monitoring) modulate same‐verb structural priming. In particular, we investigate how likely students are to repeat a sentence structure of a teacher depending on their perception of the teacher and their social monitoring tendency. Our results demonstrate that students’ tendency to imitate a sentence structure of the teacher is positively influenced by their perception of the teacher but negatively by social monitoring. We suggest that the effects may be accounted for in terms of their influence on attention and memory encoding. 相似文献

A recent study showed that specific linguistic and grammatical features of a technique commonly referred to as statement analysis are applicable across different language groups. One limitation of that study was that it used an eyewitness crime video paradigm, which might be different from writing a statement after committing an actual criminal act. We remedied that limitation by using a mock crime paradigm. In this study, three language groups (English, Spanish, and Chinese) produced statements after committing a mock crime, taking a check, in an experimental context. Certain linguistic features significantly discriminated truths from lies similarly across the different language groups, suggesting that statement analysis might be applicable as a reliable indicator of deception across languages.

Chaplains play an important role in supporting the mental health of current and former military personnel; in this study, the engagement of Department of Veterans Affairs (VA), Army, Navy, and Air Force chaplains with suicidality among their service users were examined. An online survey was used to collect data from 440 VA and 1,723 Department of Defense (DoD) chaplains as part of the VA/DoD Integrated Mental Health Strategy. Differences were noted for demographics, work setting characteristics, encountering suicidality, and self‐perceived preparation for dealing with suicidality. Compared to DoD chaplains, VA chaplains encounter more at‐risk service users, yet feel less prepared for dealing with suicidality. 相似文献

Previous study findings of psychotherapy's effect on suicide prevention have been inconsistent. This study reports the results of secondary analyses of outcome data from a short‐term depression treatment on reducing death/suicidal ideation among 158 low‐income homebound adults aged 50+. The treatment, in‐person or telehealth problem‐solving therapy (PST), compared with telephone support call, has been found effective in reducing depressive symptoms and disability among participants. Compared with support call participants, tele‐PST participants, but not in‐person PST participants, exhibited lower ideation ratings across the follow‐up period. Effect sizes at 36 weeks were 0.31 for tele‐PST and 0.17 for in‐person PST. Hopelessness mediated the effect of tele‐PST but not in‐person PST; however, in‐person PST also alleviated hopelessness, which led to lower ideation. Clinical implications of the findings are discussed. 相似文献

Prospective predictors of persistent nonsuicidal self‐injury (NSSI) were examined in adolescents admitted to an inpatient psychiatric unit for suicidal behaviors and followed naturalistically for 6 months. Seventy‐one (77%) participants reported NSSI at baseline, and 40 (56%) persisted at the 6 month follow‐up. Those who endorsed automatic positive reinforcement (APR) as the predominant reason for NSSI were more likely to persist in NSSI. Depression over follow‐up, but not at baseline, also predicted persistence. These results suggest that helping high‐risk adolescents to identify alternative ways of generating emotion(s) to counter the effects of APR that may accompany NSSI should be a high priority treatment target. 相似文献
