Needle fear typically begins in childhood and represents an important health-related issue across the lifespan. Individuals who are highly fearful of needles frequently avoid health care. Although guidance exists for managing needle pain and fear during procedures, the most highly fearful may refuse or abstain from such procedures. The purpose of a clinical practice guideline (CPG) is to provide actionable instruction on the management of a particular health concern; this guidance emerges from a systematic process. Using evidence from a rigorous systematic review interpreted by an expert panel, this CPG provides recommendations on exposure-based interventions for high levels of needle fear in children and adults. The AGREE-II, GRADE, and Cochrane methodologies were used. Exposure-based interventions were included. The included evidence was very low quality on average. Strong recommendations include the following. In vivo (live/in person) exposure-based therapy is recommended (vs. no treatment) for children seven years and older and adults with high levels of needle fear. Non-in vivo (imaginal, computer-based) exposure (vs. no treatment) is recommended for individuals (over seven years of age) who are unwilling to undergo in vivo exposure. Although there were no included trials which examined children < 7 years, exposure-based interventions are discussed as good clinical practice. Implementation considerations are discussed and clinical tools are provided. Utilization of these recommended practices may lead to improved health outcomes due to better health care compliance. Research on the understanding and treatment of high levels of needle fear is urgently needed; specific recommendations are provided.  相似文献

Social media are found to facilitate social information exchange among lesbian, gay, and bisexual (LGB) individuals who are subjected to social stigma. This study tested the protective role of LGB‐tailored social media uses and gratifications in promoting LGB group membership, which we hypothesized to reduce LGB stigma and enhance mental health among LGB individuals in Hong Kong. Based on a sample of 233 Chinese LGB individuals in Hong Kong, structural equation modeling showed evidence for our hypotheses, χ(df=62)2 = 88.20, GFI = 0.95, CFI = 0.98, NNFI = 0.98, SRMR = 0.07, RMSEA = 0.04. Community surveillance, identity expression, and emotional support on social media may promote mental health by instilling a sense of group membership and reducing stigma. Social media may build camaraderie and bolster resilience among LGB individuals that may otherwise be difficult in conservative regions.  相似文献

Although many studies have investigated individual differences in online social networking, few have examined the recent and rapidly popularized social phenomenon of the “selfie” (a selfportrait photograph of oneself). In two studies with a pooled sample of 1296 men and women, we tested the prediction that individuals who score high on four narcissism sub-scales (Self-sufficiency, Vanity, Leadership, and Admiration Demand) will be more likely to post selfies to social media sites than will individuals who exhibit low narcissism. We examined three categories of selfies: own selfies; selfies with a romantic partner; and group selfies, controlling for non-selfie photographs. Women posted more selfies of all types than did men. However, women’s selfie-posting behavior was generally unrelated to their narcissism scores. In contrast, men’s overall narcissism scores positively predicted posting own selfies, selfies with a partner, and group selfies. Moreover, men’s Vanity, Leadership, and Admiration Demand scores each independently predicted the posting of one or more types of selfies. Our findings provide the first evidence that the link between narcissism and selfie-posting behavior is comparatively weak among women than men, and provide novel insight into the social motivations and functions of online social networking.  相似文献

In Hungary, there has been limited public debate about genetically modified crops, unlike in some Western countries. The mass media has published little to inform Hungarian lay people about genetically modified (GM) crops or their relevance to the country. Nevertheless, the media did convey some general impressions, mainly from within an Anti-GM Threat framing of the issue. This mass media frame was evident in lay focus group discussions—e.g. GM crops branded a food risk, general focus on risks, health risk identified as important risk, foreign companies regarded as source of the problem and as being ‘just out for profit’, image of corn, rhetoric of deterioration, etc. This overlap supports theories which suggest that media framings provide a resource which can be appropriated for public understanding. At the same time, however, dominant media framings were also mentioned only vaguely or in a somewhat modified way. Other issues raised in the media framing, not resonating with wider cultural themes, were absent from focus group discussions (e.g. environmental concerns). And participants were also able to rely on other conversational resources (analogous reasoning and cultural themes) to formulate some additional issues beyond the media reportage.  相似文献

Abstract

Previous research has suggested that Facebook use can lead to adverse romantic relationship outcomes due to interpersonal conflicts, interactions with potential romantic alternatives, and jealousy. However, these associations have been explored mainly with undergraduates, focusing primarily on conflict rather than emotional disengagement. The current study examined the associations between Facebook addiction and marital disaffection (e.g., loss of love, emotional disengagement) amongst 138 (95 females and 43 males) cohabiting married Facebook users residing in the United States. The results revealed that Facebook addiction and marital disaffection were positively related, even after controlling for relationship commitment. Additionally, greater relationship commitment weakened the association between Facebook addiction and marital disaffection. There are likely multiple explanations for the current findings; however, results suggest that higher levels of relationship commitment may protect spouses against the negative relationship outcomes associated with Facebook addiction. Future longitudinal work with couples is needed to clarify the directionality of the relationship between Facebook addiction and marital disaffection.  相似文献

Ten therapists who were already trained and experienced in eye movement desensitization and reprocessing (EMDR) received training in progressive counting (PC), a newer trauma resolution method. Nineteen volunteers with single-incident trauma or loss were assigned to a therapist and then randomized to treatment condition; 15 completed treatment to termination criteria or until the 4th session. Participants in both conditions experienced significant reductions in post-traumatic stress disorder (PTSD) symptoms, memory-related distress, and presenting problems at one week posttreatment, and maintained at 12-week follow-up, with no significant differences in outcomes, treatment efficiency, or dropout rate. The preliminary findings of this pilot study suggest that PC is an efficient, well-tolerated, and effective trauma treatment that is relatively easy for therapists to master.  相似文献

Several studies have employed confirmatory factor analysis (CFA) to examine the latent structure of the Posttraumatic Stress Disorder (PTSD) Checklist (PCL; Weathers, Litz, Herman, Huska, & Keane, 1993), a measure that assesses PTSD symptomatology. Findings have failed to support the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision [DSM–IV–TR]; American Psychiatric Association, 2000) PTSD model, consisting of reexperiencing, avoidance/numbing, and arousal factors, and no consensus has emerged regarding the best fitting alternative model. Additionally, most studies have utilized homogeneous trauma samples. This study used CFA to examine the PCL factor structure in a sample with exposure to various traumatic events. Superior fit was demonstrated by a model specifying reexperiencing, avoidance, dysphoria, and arousal factors.  相似文献
