Neuroimaging research has suggested that activity in the amygdala, center of the socioemotional network, and functional connectivity between the amygdala and cortical regions are associated with caregiving behaviors in postpartum mothers. Anxiety is common in the early postpartum period, with severity ranging from healthy maternal preoccupation to clinical disorder. However, little is known about the influence of anxiety on the neural correlates of early caregiving. We examined these relationships in a community cohort of 75 postpartum women (ages 18–22; predominantly low-SES, minority race) who listened to infant cry sounds while undergoing an fMRI assessment. Maternal self-reported symptoms of anxiety were mostly within the subclinical range. Positive and negative caregiving behaviors during filmed face-to-face mother–infant interactions were coded by independent observers. The results from whole-brain analyses showed that anxiety severity moderated the brain–maternal behavior relationships. Specifically, our results showed that the higher a mother’s anxiety, the stronger the association between positive caregiving (i.e., maternal warmth and involvement) and amygdala–right posterior superior temporal sulcus (amygdala–RpSTS) functional connectivity. These results remained significant when we controlled for symptoms of depression and contextual variables. These findings suggest that functional connectivity between the amygdala and a social perception region (RpSTS) plays a particularly important role for anxious mothers in facilitating their positive parenting. These findings extend our understanding of the specific neural circuits that support positive maternal caregiving in the context of maternal anxiety, and they may help inform the future design of personalized and effective interventions. 相似文献

The behaviour of offenders and victims in 116 cases of group robbery (61 commercial, 55 personal) was examined. Four interpersonal themes were evident: dominance, submission, co‐operation and hostility. These themes are governed by the principles of complementarity such that offender dominance elicits victim submission (reciprocity) and vice versa, while co‐operative offenders tend to elicit victim co‐operation (correspondence). Hostile offences were hypothesised as eliciting hostility in victims, but few victims in the sample demonstrated active resistance. The existence of behavioural themes suggests that offenders within the same group behave in a homogenous fashion, which is explained by reference to group norms and processes of modelling. Further, differences in interpersonal themes were evident between commercial and personal robberies. Commercial robberies tend to involve greater levels of co‐operation than personal robberies, while personal robberies involve more hostility than commercial robberies. This is discussed in terms of situational and motivational elements of the robberies. Aggr. Behav. 32:330–342, 2006. © 2006 Wiley‐Liss, Inc. 相似文献

While suicide prevention efforts are increasingly being delivered using technology, no scales have been developed specifically for web‐based use. The Suicidal Ideation Attributes Scale (SIDAS) was developed and validated as a brief, web‐based measure for severity of suicidal ideation, using an online survey of Australian adults (n = 1,352). The SIDAS demonstrated high internal consistency and good convergent validity. Frequency and controllability of thoughts were more strongly associated with suicide plans and attempts than other attributes assessed. Scores ≥ 21 indicated high risk of suicide behavior. The SIDAS appears to be a valid web‐based measure for severity of suicidal ideation. 相似文献

We examined teenagers' attitudes about the role of mental illness in suicidal behavior and the relationship between these attitudes and suicide risk. Serious suicidal ideation or behavior and associated risk factors (gender, depression, substance problems, and first‐hand experience with a suicidal peer) were assessed in 2,419 students at six New York high schools. Less than one fifth of students thought that mental illness was a major contributor to suicide. Suicidal adolescents and those at risk were less likely than their nonsuicidal and low‐risk counterparts to associate suicide with mental illness. Our findings contribute to the debate over whether accepting attitudes toward suicide increase suicide risk. 相似文献

Public knowledge and attitudes toward suicide may influence help‐seeking for suicidality. This study aimed to identify correlates of suicide attitudes and knowledge. Australian adults were invited to complete an online survey, with 1,286 responders. Less exposure to suicide, older age, male gender, less education, and culturally diverse backgrounds were associated with poorer knowledge; while younger age, male gender, and culturally diverse backgrounds were associated with more stigmatizing attitudes toward people who die by suicide. The results suggest suicide literacy and stigma reduction programs would benefit community members, particularly males and individuals from culturally diverse backgrounds. 相似文献
