Our study examines risk factors for metabolic syndrome on admission to an acute psychiatric facility and the incidence of medical referrals at discharge. Data on demographics, risk factors for metabolic syndrome, other health risk factors, medications, related diagnoses, and primary care providers and referrals were collected from 125 psychiatric patient charts. Comparison analysis was done for two groups: those with two or more risk factors for metabolic syndrome and those with less than two risk factors. Differences between groups were statistically significant for age, waist circumference, body mass index, high-density lipoprotein, triglycerides, and fasting glucose levels. Few patients were referred to their primary care provider for follow-up care. This study has clinical implications for improving assessment of psychiatric patients at risk for developing metabolic syndrome, for designing interventions to help patients adopt lifestyle changes to mitigate these risks, and for working toward fuller integration of psychiatric and primary care. 相似文献

With the decline of public trust in corporate America, organizations must consider ways to improve their relationships with key publics. One of the best strategies to build trust is through engaging in transparent communication (Rawlins, 2009). The increase in the popularity of social media has brought both challenges and opportunities for organizational transparency. This study used multiple methods to explore whether public relations professionals believe they are using social media to communicate transparently, to investigate how social media can be used to improve transparency along with its benefits and challenges, and to identify how transparency is used in social media campaigns. 相似文献

In the family therapy literature there is increasing interest in the dialogical approach, particularly as it becomes well‐grounded in psychotherapy research. One embodiment is ‘open dialogues’, which has developed over a 30‐year period in Western Lapland, Finland. This paper outlines my experience of visiting Keropudas Hospital in Tornio, Finland, the birthplace of open dialogues. It explores the seven theoretical principles of open dialogues, associated elements of clinical practice, and the therapist use of self. The author utilises these aspects to reflect on dialogical moments through words and images based on three conceptual themes, which illustrate the relevance of open dialogues for family therapy practitioners and their contexts. 相似文献

The systematic errors that are induced by a combination of human memory limitations and common survey design and implementation have long been studied in the context of egocentric networks. Despite this, little if any work exists in the area of random error analysis on these same networks; this paper offers a perspective on the effects of random errors on egonet analysis, as well as the effects of using egonet measures as independent predictors in linear models. We explore the effects of false-positive and false-negative error in egocentric networks on both standard network measures and on linear models through simulation analysis on a ground truth egocentric network sample based on facebook-friendships. Results show that 5–20% error rates, which are consistent with error rates known to occur in ego network data, can cause serious misestimation of network properties and regression parameters. 相似文献

Approaches used by employee assistance programs to address perpetration of intimate partner violence
Walters JL Pollack KM Clinton-Sherrod M Lindquist CH McKay T Lasater BM 《Violence and victims》2012,27(2):135-147
Employee Assistance Programs (EAPs) are workplace resources available to employees with problems impacting work performance. EAPs are well-positioned to address intimate partner violence (IPV), a major public health problem with workplace impacts. A purposeful sample of 28 EAPs across the United States was surveyed to identify policies and programs to address IPV, including perpetration. Most EAPs did not report having standardized approaches for addressing IPV perpetration. EAPs also described significant barriers to identifying IPV perpetrators, with the majority relying on self-disclosure on the part of the perpetrator when contacting the EAP. These results suggest that many EAPs--even when interacting with employees who present with issues known to correlate with IPV--are missing a potential opportunity to assess and intervene with IPV perpetrators. 相似文献

This study was a systematic extension of Karmali, Greer, Nuzzulo-Gomez, Ross, and Rivera-Valdes (2005) and Ahearn, Clark, MacDonald, and Chung (2007). We investigated the effects of a tact correction procedure on stereotypic vocalizations in 4 children diagnosed with autism who ranged in age from 6 to 16 years. Participants had limited vocal verbal repertoires and were primarily dependent on prompts for the emission of appropriate vocalizations. A multiple-baseline design across participants was used. Data were collected on instances of stereotypic vocalizations and independent tacts during baseline conditions and on instances of stereotypic vocalizations, independent tacts, and echoic-tacts during intervention. Procedural integrity and social validity data were also obtained. The results indicated a decrease in stereotypic vocalizations for 3 of the 4 participants and a slight increase in appropriate vocal verbal behavior (i.e., tacting) for all participants. The study provides support for the use of tact correction procedures to decrease stereotypic vocalizations and increase appropriate vocalizations in children with autism. 相似文献

Mistreatment and self-reported emotional symptoms: results from the National Elder Mistreatment Study 总被引:1,自引:1,他引:0
Many community-residing older adults in the United States report past year mistreatment; however, little is known about mental health correlates of abuse. This study investigated whether a recent history of emotional, physical, or sexual abuse is associated with self-reported emotional symptoms (e.g., anxiety, depression) among a representative sample of older adults. Results demonstrated that each abuse type increased likelihood of reporting emotional symptoms; when other known correlates were controlled, only emotional abuse remained a significant predictor. Additional study of mistreatment-related correlates of depression and anxiety is needed, with a focus on the often overlooked category of emotional mistreatment. 相似文献
