个体心理模式对慢性疾病预后的探讨

21世纪,慢性疾病逐渐成为威胁人类健康的重要原因。然而其预后一直不理想,对慢性疾病患者的心理模式进行了分析,结合工作实际,提出慢性疾病患者如何看待疾病和自身———有意识的或无意识的———在很大程度上决定了疾病的预后。     

高血压防治模式探讨

高血压是一种严重危害人体健康的生活方式病,也是一种心身疾病。它的危害性较之烈性传染病有过之而无不及。但高血压防治仍停留在“专家模式”一头热的困局上,临床指南与临床实践有较大差距。高血压知晓率、治疗率和控制率均低。造成“三低”的原因有:(1)对高血压这种慢性、流行性疾病的危害性认识不足;(2)健康观念存在误区;(3)迷信一劳永逸的治疗方法;(4)人群防治知识缺乏、素质低下。高血压防治是一个科学的综合管理过程,只有从健康教育入手,全面提高人群高血压防治知识水平,才能开创高血压防治的新局面。健康追求不应只是个人行为,还必须是群体行为和社会行为。人群有了健康观念、健康心态和健康智慧,高血压的防治才能取得真正的成效。     

积极心理治疗模式的特色及启示

。积极心理治疗是以积极心理学思想为理论指导的一种心理疗法。作为心理治疗中的一个新生事物,它从人发展的可能性和能力出发,以解决冲突为核心,关注积极的人格特质,在治疗中借助讲故事的形式提供跨文化的观点。这一较符合人性特点的心理治疗模式,扩展了人们对心理治疗性质的认识,推进了心理治疗的本土化发展。     

The temporal pattern of unconstrained drinking: Rats' responses to inversion and identity constraints

Rats obtained all of their water by licking a metal tube during a series of daily 1-hour sessions. When the tube was freely available throughout, each rat showed the classic temporal pattern of unconstrained drinking: As the session progressed, drinking bouts generally grew shorter and pauses grew longer. In subsequent sessions the tube was opened and closed independently of the rat's behavior, on a schedule that gave the rat a chance to duplicate the exact inverse of its unconstrained baseline pattern. Thus, as the inversion session progressed, the opportunities to drink generally grew longer and the enforced pauses grew shorter. When the rats were forced away from their unconstrained patterns of drinking and pausing, their total time spent drinking consistently fell short of previous values, but total licks and volumetric intake remained at previous levels. The same results occurred under an identity schedule, a series of openings and closings that duplicated the unconstrained pattern of drinking and pausing. The results have implications for theories that assume that instrumental performance under schedule constraint derives from the animal's defense of a measured set-point.     

A new proof for monotone likelihood ratio for the sum of independent bernoulli random variables

By use of an inequality of Marcus and Lopes for elementary symmetric functions, a new proof is presented for the following result by Ghurye and Wallace: Given that the independent random variablesX _j are Bernoulli with success probabilityp _j () strictly between 0 and 1 and nondecreasing in, the sum X _j has monotone likelihood ratio.     

人格特征对胃癌发病的影响

使用Ｃ型行为特征问卷、生活事件量表和ＲＢＣ－Ｃ_（３ｂ）Ｒ、ＲＢＣ－ＩＣ、ＲＣＩＡ、ＣＩＣ和Ｃ_３等免疫功能的检测,调查和检测了３０名胃癌患者和５０名健康者。结果表明：（１）胃癌组比健康组在焦虑、抑郁、愤怒内泄、控制等方面得分高,在愤怒外泄、乐观、社会支持等方面得分低;（２）胃癌患者在确诊前８年内有７６％的患者遇到生活事件,在确诊前３年内有６２％的患者遇到生活事件;（３）胃癌组ＲＢＣ－Ｃ_（３ｂ）Ｒ含量低,ＲＣＩＡ含量和ＣＩＣ水平上升。初步结论：胃癌的发生与患者的一些行为特点有关,主要是抑郁并不表达愤怒;生活事件可作为应激源诱发胃癌;其机制可能与免疫功能有关。     

Constructing measures with maximum reliability

The scoring of response vectors to give maximum test-retest correlation is investigated. Simple sufficiency arguments show that the form of the best scores is very restricted. A general method is given for finding the best scores, deriving the best scores for the normal factor model, and showing by calculation of several particular cases that for a standard model for binary response it is easy to approximate the best scores.
