Distinguishing types of social withdrawal in children: Internalizing and externalizing outcomes of conflicted shyness versus social disinterest across childhood

Little research has examined the effect of subtypes of social withdrawal on the development of psychopathology across childhood.Parents of 493 children (220 females) completed a measure of their child’s conflicted shyness and social disinterest as well as the Child Behavior Checklist (CBCL) when their child was age 3, and again at age 6. When children were age 9, parents completed the CBCL.From 3 to 6, conflicted shyness predicted increases in anxiety symptoms in boys and girls, and predicted depressive symptoms in boys. From 6 to 9, social disinterest predicted increases in anxiety symptoms in girls and boys, and predicted increases in depressive symptoms in boys. In addition, in boys, conflicted shyness at age 6 predicted increases in externalizing symptoms at age 9.Conflicted shyness appears to be particularly problematic in early to middle childhood, while social disinterest appears to be more maladaptive in later childhood, with some differences by gender.     

在美国样本中母亲抑郁症状与儿童退缩的关系:教养行为的中介作用

本研究通过使用美国国家儿童健康与人类发育研究所的纵向研究数据建立分层线性模型,探究在儿童的早期发展中,母亲抑郁症状对儿童的社会性退缩的影响,以及母亲的教养行为在这一关系中的中介作用,结果发现：（1）在儿童24~54个月期间,随着母亲抑郁症状的升高,儿童的社会性退缩也随之升高;（2）母亲抑郁症对儿童社会性退缩的影响存在着性别差异,与女孩相比,男孩的社会性退缩更容易受到母亲抑郁症状的影响;（3）在男孩中,消极的教养行为在母亲抑郁症状与男孩的社会性退缩之间起到了中介作用,而在女孩中,这一中介作用并不显著。     

Drug Tolerance, Drug Addiction, and Drug Anticipation

ABSTRACT— Environmental cues associated with drugs often elicit withdrawal symptoms and relapse to drug use. Such cues also modulate drug tolerance. The contribution of drug-associated stimuli to withdrawal and tolerance is emphasized in a Pavlovian-conditioning analysis of drug administration. Conditional responses occur in the presence of cues that have been associated with the drug in the past, such as the setting in which the drug was taken. These conditional responses mediate the expression of tolerance and withdrawal symptoms. Recently, it has become apparent that internal predrug cues, as well as environmental cues, elicit pharmacological conditional responses that contribute to tolerance and withdrawal. Such internal cues include cognitive or proprioceptive cues incidental to self-administration, drug-onset cues that are experienced shortly after administration, and emotional cues. According to the conditioning analysis, addiction treatment should incorporate learning principles to extinguish the association between stimuli (environmental and internal) present at the time of drug administration and the effects of the addictive drug.     

State mood,task performance,and behavior at work: A within-persons approach

We examine the intra-individual relationships between state mood and the primary components of the individual-level criterion space (task performance, organizational citizenship behavior, and work withdrawal) as they vary within the stream of work. Using experience-sampling methods, 67 individuals in a call center responded to surveys on palmtop computers at random intervals 4–5 times each day for 3 weeks (total N = 2329). These data were matched to objective task performance obtained from organizational call records (total N = 1191). Within-persons, periods of positive mood were associated with periods of improved task performance (as evidenced by shorter call time) and engaging in work withdrawal. Trait meta-mood moderated these relationships. Specifically, individuals who attended to their moods had a stronger relationship between mood and speed of task performance (call time) and individuals able to repair their mood cognitively evidenced a weaker relationship between mood and withdrawal. Implications and the use of within-persons designs are discussed.     

Implementation and Assessment of an Empirically Validated Intervention Program to Prevent Tobacco Use Among African-American Middle-School Youth

Evaluated Project Towards No Tobacco Use (TNT), a tobacco-use prevention program delivered in schools with primarily African-American students. Students were assigned randomly by classroom to either the intervention (n=58) or to a no-treatment control group (n=40). Students in the intervention group received a curriculum-based program over the course of 10 sessions. Pre-and post-assessments of tobacco knowledge, attitudes, communication, peer refusal, and smoking tendency were gathered. Students in the intervention group differed from their peers in the control group by evidencing greater knowledge and communication skills. We found this tobacco-use prevention program useful for African-American students.This investigation was supported in full by the American Cancer Society Grant Award ACS IRG 97-151.     

儿童同伴关系对孤独感的影响

以571名小学三、四、五、六年级的儿童为被试,考察了儿童社会喜好、友谊质量、消极退缩、社交自我知觉与孤独感的关系,检验了不同水平同伴关系变量对孤独感的影响。结果表明,儿童的同伴关系(同伴接纳、友谊质量、社交自我知觉)能显著预测其孤独感体验,其中,处于同伴关系个体水平的社交自我知觉对孤独感的预测作用最大,其次分别为双向关系水平的友谊质量和群体接纳水平的同伴接纳,而处于人际交互水平的消极退缩在控制了其他水平同伴关系变量的影响下,并不能显著预测其孤独感体验。     

自我概念在父母情感关爱与儿童发展间的完全中介效应

运用问卷法,对北京612名中小学生及其父母分别进行了儿童孤独退缩行为、自我概念及父母情感关爱行为测试,运用LISEREL软件对数据的分析结果表明:父母情感关爱行为通过儿童自我概念的完全中介作用,对儿童的孤独退缩行为起到明显的抑制作用;在父母情感关爱行为和儿童学业成就之间,儿童的学业自我概念也起到了明显的完全中介效果.从而支持了儿童自我概念在父母情感关爱与儿童发展间的完全中介地位.     

吉林省医务人员吸烟现况及知识态度分析

为了更好地了解吉林省医务人员的吸烟状况,为进一步开展控烟工作提供科学依据,对吉林省50家医疗机构的3787名医务人员进行问卷调查,调查结果显示,男性医务人员吸烟率较高；医务人员对烟草危害认识不全面,控烟意识较为薄弱.应加强对医务人员烟害知识等方面的培训,以改变其吸烟行为、提高控烟责任意识.     

Effectiveness of a consultation intervention to promote tobacco control policies in Northwest Indian tribes: Integrating experimental evaluation and service delivery

A quasi-experimental replication of an intervention for promoting tobacco control policies in Northwest Indian tribes is described and the process of intervention including issues of collaboration among research institutions and Indian organizations is discussed. The policy intervention was evaluated using a pretest-posttest design wherein 20 tribes that had served as wait-list controls now received the intervention. The intervention comprised a tribal representative attending a kickoff orientation; follow-up visits to the tribes; distribution of tobacco policy workbooks; and phone call consultations. Policy status and stringency were assessed by means of telephone interviews with two key contacts per tribe, and by a count of enacted policies. There were significant pre-post changes in the primary outcome measure, a composite summary score of tobacco policy stringency, and changes were also reflected in enacted policies. The intervention effects observed were similar to those found in the prior randomized trial and suggest a robust, disseminable intervention. Much of the success achieved was attributed to the role of an Indian organization in planning the project and implementing the intervention and evaluation protocols.     

Mobilizing positive reinforcement in communities to reduce youth access to tobacco

A community intervention to mobilize positive reinforcement for not selling tobacco to young people was evaluated. The intervention had five components: (a) mobilization of community support, (b) merchant education, (c) changing consequences to clerks for selling or not selling to those under 18, (d) publicity about clerks’ refusals to sell, and (e) feedback to store owners or managers about the extent of their sales to adolescents. A multiple baseline design experiment was conducted, in which two small Oregon communities received the intervention, while two others continued in baseline. Outlets’ willingness to sell was assessed repeatedly by teenage volunteers. The intervention significantly reduced the proportion of stores willing to sell. Mobilizing socia and material reinforcement for stores not selling tobacco to young people is a viable means of reducing such sales. It may be especially valuable in communities where laws against sales to minors go unenforced. This paper supported in part by the National Cancer Institute Grant CA38273.
