There are meager prospective data from nonclinical samples on the link between anxiety disorders and suicide or the extent to which the association varies over time. We examined these issues in a cohort of 309,861 U.S. Air Force service members, with 227 suicides over follow‐up. Mental disorder diagnoses including anxiety, mood, and substance‐use disorders (SUD) were based on treatment encounters. Risk for suicide associated with anxiety disorders were lower compared with mood disorders and similar to SUD. Moreover, the associations between mood and anxiety disorders with suicide were greatest within a year of treatment presentation.  相似文献

Children aged 3½ to 6½ years viewed pictures of common objects presented either once or three times on one of two consecutive days. A different hand puppet was used to present the pictures on each day, providing both perceptual and temporal cues to source. At test, old (studied) and new (non‐studied) pictures were presented for item recognition and source identification. Results showed that both item and source accuracy were higher for older (M = 5; 9 years) than younger children (M = 4; 6 years). Significant interactions between Age and Day of study were found for both item and source accuracy. For younger children, accuracy was higher for pictures studied on Day 1 than Day 2 (significant for source identification but not item recognition), whereas older children showed the opposite pattern: Higher accuracy for Day 2 than Day 1 (significant for item recognition but not source identification). Results are interpreted with respect to proactive interference and response bias. The utility of signal detection theory measures in determining the basis of age differences in performance of source identification is discussed.  相似文献

When the Veterans Crisis Line (VCL) was implemented, it was uncertain if veterans, and particularly older male veterans, would utilize the service. We examined VCL use by a growing group of veterans at increased risk for suicide: those aged 60 and older. Real‐time clinical data were gathered from a weekly random sampling of calls. Approximately 25% of calls were from veterans aged 60 or older; over 80% reported benefit from the call. Several significant differences in presenting concerns between older and younger callers were found. Targeted outreach to encourage older veterans to use the VCL is suggested.  相似文献

This randomized trial examined the effects of 2 oncologist-based exercise interventions--recommendation only (RO) and recommendation plus referral (RR)--versus usual care (UC) on social-cognitive constructs from the theory of planned behavior (TPB). The authors also examined whether the TPB mediated the significant effect of the RO intervention on exercise and explained the null effect of the RR intervention. Independent t tests revealed that both interventions had significant effects on TPB constructs; however, only the RO intervention impacted perceived behavioral control (PBC). Path analyses indicated that PBC was the only construct with a direct effect on exercise and that it mediated the effect of the RO intervention on exercise and explained the null effect of the RR intervention.  相似文献
