目的 探讨情景模拟健康教育在晚期肺癌患者癌痛管理中的应用效果,旨在提高晚期肺癌患者提高癌痛应对和管理能力。方法 采用便利抽样法,选取2019年5月-2020年5月在同济大学附属上海市肺科医院肿瘤科住院的晚期肺癌患者60例为研究对象,按其住院时间先后顺序分为对照组(n=30)和观察组(n=30)。对照组患者给予肺癌常规护理及健康教育,观察组在其基础上给予情景模拟健康教育干预,主要围绕正确认识癌痛、癌痛自我评估、癌痛应对、躯体功能应对和负性心理情绪调试等展开。分别于患者入院第1天及第7天评估患者疼痛管理效能及情绪状况。结果 入院第1天,两组患者慢性疼痛自我效能感量表和中文版简式-简明心境问卷得分组间比较,差异无统计学意义(P>0.05),入院第7天,组间比较有统计学差异(P<0.05)。结论 情景模拟健康教育可有效提高晚期肺癌患者疼痛管理自我效能,改善患者负性心理情绪,进而提高其生活质量,值得临床进一步应用和推广。  相似文献

The objective of this study was to evaluate the clinical‐ and cost‐effectiveness of Intensive Short‐Term Dynamic Psychotherapy (ISTDP) for generalized anxiety disorder (GAD). We further aimed to examine if a key clinical process within the ISTDP framework, termed the level of mobilization of unprocessed complex emotions (MUCE), was related to outcome. The sample consisted of 215 adult patients (60.9% female) with GAD and comorbid conditions treated in a tertiary mental health outpatient setting. The patients were provided an average of 8.3 sessions of ISTDP delivered by 38 therapists. The level of MUCE in treatment was assessed from videotaped sessions by a rater blind to treatment outcome. Year‐by‐year healthcare costs were derived independently from government databases. Multilevel growth models indicated significant decreases in psychiatric symptoms and interpersonal problems during treatment. These gains were corroborated by reductions in healthcare costs that continued for 4 years post‐treatment reaching normal population means. Further, we found that the in‐treatment level of MUCE was associated with larger treatment effects, underlining the significance of emotional experiencing and processing in the treatment of GAD. We conclude that ISTDP appears to reduce symptoms and costs associated with GAD and that the ISTDP framework may be useful for understanding key therapeutic processes in this challenging clinical population. Controlled studies of ISTDP for GAD are warranted.  相似文献

ABSTRACT

Research on facial expressions in individuals with Down syndrome (DS) has been conducted using photographs. Our goal was to examine the effect of motion on perception of emotional expressions. Adults with DS, adults with typical development matched for chronological age (CA), and children with typical development matched for developmental age (DA) viewed photographs and video clips of facial expressions of: happy, sad, mad, and scared. The odds of accurate identification of facial expressions were 2.7 times greater for video clips compared with photographs. The odds of accurate identification of expressions of mad and scared were greater for video clips compared with photographs. The odds of accurate identification of expressions of mad and sad were greater for adults but did not differ between adults with DS and children. Adults with DS demonstrated the lowest accuracy for recognition of scared. These results support the importance of motion cues in evaluating the social skills of individuals with DS.  相似文献

Overcoming specific fears and subsequent anxiety can be greatly enhanced by the presence of familiar social partners, but the neural circuitry that controls this phenomenon remains unclear. To overcome this, the social interaction (SI) habituation test was developed in this lab to systematically investigate the effects of social familiarity on anxiety-like behavior in rats. Here, we show that social familiarity selectively reduced anxiety-like behaviors induced by an ethological anxiogenic stimulus. The anxiolytic effect of social familiarity could be elicited over multiple training sessions and was specific to both the presence of the anxiogenic stimulus and the familiar social partner. In addition, socially familiar conspecifics served as a safety signal, as anxiety-like responses returned in the absence of the familiar partner. The expression of the social familiarity-induced anxiolysis (SFiA) appears dependent on the prefrontal cortex (PFC), an area associated with cortical regulation of fear and anxiety behaviors. Inhibition of the PFC, with bilateral injections of the GABAA agonist muscimol, selectively blocked the expression of SFiA while having no effect on SI with a novel partner. Finally, the effect of D-cycloserine, a cognitive enhancer that clinically enhances behavioral treatments for anxiety, was investigated with SFiA. D-cycloserine, when paired with familiarity training sessions, selectively enhanced the rate at which SFiA was acquired. Collectively, these outcomes suggest that the PFC has a pivotal role in SFiA, a complex behavior involving the integration of social cues of familiarity with contextual and emotional information to regulate anxiety-like behavior.  相似文献

ABSTRACT

Theory of mind describes the ability to engage in perspective-taking, infer mental states, and predict intentions, behavior, and actions in others. Theory of mind performance is associated with foundational cognitive and socioemotional skills, including verbal ability (receptive and expressive vocabulary), executive function (inhibitory control and working memory), and emotion knowledge. In a sample of 354 children from low-income households, theory of mind and foundational skills were directly assessed before and after kindergarten. Results indicate emotion knowledge, inhibitory control, and expressive language predicted improvement in theory of mind. Expressive language also served as a moderator such that children with low expressive language failed to improve in theory of mind regardless of initial theory of mind performance.  相似文献

We conducted a prospective, single-blind, parallel group, controlled trial to evaluate effects of written emotional expression in patients receiving intensive treatment for cocaine dependence in a residential-unit setting. Randomization to the emotional expression treatment produced changes in blood pressure and mood during writing sessions, possibly because of its ability to stimulate active coping behavior. At an initial follow-up visit, patients that had received written emotional expression reported lower values for craving intensity and were less likely to self-report use of cocaine. These results may indicate a therapeutic effect of written emotional expression during recovery from cocaine dependence.  相似文献
