CAREGIVER–CHILD INTERACTION,CAREGIVER TRANSITIONS,AND GROUP SIZE AS MEDIATORS BETWEEN INTERVENTION CONDITION AND ATTACHMENT AND PHYSICAL GROWTH OUTCOMES IN INSTITUTIONALIZED CHILDREN

This report describes a secondary analysis of data from a comprehensive intervention project which included training and structural changes in three Baby Homes in St. Petersburg, Russian Federation. Multiple mediator models were tested according to the R.M. Baron and D.A. Kenny ( 1986 ) causal‐steps approach to examine whether caregiver–child interaction quality, number of caregiver transitions, and group size mediated the effects of the intervention on children's attachment behaviors and physical growth. The study utilized a subsample of 163 children from the original Russian Baby Home project, who were between 11 and 19 months at the time of assessment. Results from comparisons of the training and structural changes versus no intervention conditions are presented. Caregiver–child interaction quality and number of caregiver transitions fully mediated the association between intervention condition and attachment behavior. No other mediation was found. Results suggest that the quality of interaction between caregivers and children in institutional care is of primary importance to children's development, but relationship context may play a less direct mediational role, supporting caregiver–child interactions.     

FATHER–CHILD INTERACTIONS AT 3 MONTHS AND 24 MONTHS: CONTRIBUTIONS TO CHILDREN'S COGNITIVE DEVELOPMENT AT 24 MONTHS

The quality of father–child interactions has become a focus of increasing research in the field of child development. We examined the potential contribution of father–child interactions at both 3 months and 24 months to children's cognitive development at 24 months. Observational measures of father–child interactions at 3 and 24 months were used to assess the quality of fathers’ parenting (n = 192). At 24 months, the Mental Developmental Index (MDI) of the Bayley Scales of Infant Development, Second Edition (N. Bayley, 1993 ) measured cognitive functioning. The association between interactions and cognitive development was examined using multiple linear regression analyses, adjusting for paternal age, education and depression, infant age, and maternal sensitivity. Children whose fathers displayed more withdrawn and depressive behaviors in father–infant interactions at 3 months scored lower on the MDI at 24 months. At 24 months, children whose fathers were more engaged and sensitive as well as those whose fathers were less controlling in their interactions scored higher on the MDI. These findings were independent of the effects of maternal sensitivity. Results indicate that father–child interactions, even from a very young age (i.e., 3 months) may influence children's cognitive development. They highlight the potential significance of interventions to promote positive parenting by fathers and policies that encourage fathers to spend more time with their young children.     

Intergenerational transmission of qualities of the parent–child relationship in the population-based Young Finns Study

We examined the intergenerational transmission of parent–child relationship qualities in a population-based Finnish sample of 1418 participants (G2) and their mothers (G1). At baseline, G1 (Mage = 38) reported qualities of the parent–child relationship in terms of emotional warmth and acceptance towards G2 (age range 3–18). After 28 years, G2 (Mage = 39) rated the qualities of the parent–child relationship regarding their own children using the same questionnaire. Emotional warmth and acceptance were transmitted across generations even after controlling for demographic and family characteristics in both generations. The transmission was stronger for emotional warmth than acceptance. For emotional warmth, intergenerational transmission was stronger for men than women. The findings provide evidence for the long-term transmission of parenting quality across generations.     

Same-sex parent families in Italy: Validation of the Coparenting Scale-Revised for lesbian mothers and gay fathers

Even though Italy is still struggling to establish equal rights and access to assisted reproduction techniques for sexual minorities, an increasing number of lesbian women and gay men are now becoming parents. There are only a few studies that have evaluated coparenting in same-sex couples. However, these addressed adoptive couples and not the lesbian and gay parent families through donor insemination or surrogacy, respectively. This study examined the psychometric properties of the Coparenting Scale-Revised and its relationship with dyadic adjustment, discipline management, and internalized sexual stigma in Italian same-sex-planned families. The factor structure showed a satisfactory internal consistency and criterion validity with correlates of coparenting behaviours. While Family Integrity factor was confirmed, Disparagement and Reprimand dimensions collapsed into Conflict factor. Non-genetic parents showed lower levels of conflict than genetic parents. Most importantly, coparenting emerged as a significant function not shaped by gender, but influenced by parental status and internalized sexual stigma.     

人工椎间盘置换术中的循证医学证据

循证医学（evidence—based medicine,EBM）作为一门新兴的交叉学科越来越广泛地被用来进行临床评估和决策。人工椎间盘置换技术的发展为椎间盘退行性病变的治疗提供了符合现代医学模式的新方法。循证医学在人工椎间盘置换研究中的应用不仅有助于为其提供可信、有力的临床证据,而且有丰富的哲学内涵。     

3~5岁儿童对假装的辨认和对假装者心理的推断

研究设置了三种条件：玩具条件、替代物条件和虚构物条件;测查了3~5岁的儿童对假装的辨认和对假装者心理的推断。结果表明：(1) 大部分3岁儿童就能辨认假装,但是对假装心理的推断到5岁才逐步形成;(2) 3~5岁儿童对假装的辨认和对假装者心理的推断还受支持物的影响;(3) 3~5岁的学前儿童主要倾向于从外部特点理解假装     

3~5岁儿童气质活动性与父母教养方式的关系

采用实验室观察和问卷法考察3~5岁儿童气质活动性与父母教养方式之间的关系。结果发现：（1）3~5岁儿童气质活动性与父母教养方式之间存在相互关系。不同活动性儿童的父母在溺爱性和放任性上有显著差异。（2）父母对3~5岁不同活动性儿童的教养方式存在性别差异。3~5岁不同活动性的男孩其父母的教养方式没有差异。而3~5岁不同活动性女孩其父母教养方式在溺爱性和放任性上差异显著。     

2岁幼儿的社会朝向反应——本质及功能

本研究以66对17至32个月的幼儿和母亲为研究对象,研究了在实验室情境中,幼儿在不同实验情境下对母亲的社会朝向反应,并探讨了幼儿社会朝向行为的功能以及母亲的行为对幼儿社会朝向反应的影响。结果显示,（1）大多数幼儿在实验中都表现出了至少一次的社会朝向反应,社会朝向反应的发生是酱遍的;（2）在不同情境中,幼儿的社会朝向反应不同,在积极的情境中,社会朝向反应有分享情绪经历的功能;在抗拒诱惑的任务中,社会朝向行为与获得支持有关;（3）母亲对情境的非信息性反应对幼儿的社会朝向行为有影响,社会朝向是幼儿对社会情境的适应性行为,对这种非语言的情感交流行为的研究可以帮助我们探究幼儿情绪社会化的过程。     

Simulating mother–child interaction: exploring two varieties of a non‐linear dynamic systems approach1

In theoretical analyses of early mother–child interaction, it has been argued that interaction should be studied in its flow over time, and that the behaviour of each interactant is likely to be non‐linearly determined. The mother–child dyad can be seen as a non‐linear dynamic system, the development of which is determined by the mutual relations between its elements. The present study is based on the idea that computer simulations can be used to find out what kind of empirical implication these ideas have. Accordingly, we describe two non‐linear dynamic systems‐based models for simulating mother–child interaction, i.e. a connectionist network model and a logistic growth model. Three determinants of the nature of the interaction, i.e. the child's irritability, the mother's sensitive responsiveness, and the intensity of an external stressor bothering the child, are varied systematically. Although the results of both simulations differed considerably, they shared the fact that small changes in stressor intensity produced abrupt changes from one type of interaction to another. In addition, increasing stressor intensity sometimes had the paradoxical effect of resulting in less, rather than more, distress on the side of the child. Though irritability and responsiveness were varied in a less fine‐grained way than stressor intensity, the results suggest that similarly small differences in these dimensions at different parts of the dimension's scale range have differentially strong effects on the nature of the interaction. It is concluded that these simulations help us to specify the nature of empirically researchable phenomena that are to be expected, given the assumptions listed above. Further elaboration of the models and comparison with longitudinal empirical data is needed to answer further theoretical and practical questions. Copyright © 2000 John Wiley & Sons, Ltd.
