Perceived behavioural control,subjective norms,attitudes and intention to use condom: A longitudinal cross-lagged design

Based on the Theory of Planned Behaviour (TPB), the purpose of this investigation was to examine the directionality of the association among condom use, intention, attitudes, subjective norms and perceived behavioural control. The present study investigated the nature of these relationships using a longitudinal cross-lagged design applied to data from a cohort of 958 randomly selected Italian adults. Using structural equation modelling, two cross-lagged panel analyses revealed reciprocal relationships between intention and attitudes and between intention and condom use. Contrary to expectations, baseline subjective norms and perceived behavioural control did not predict subsequent intention to use condom when controlled for the autoregressive effect of intention at T1 on the same variable at T2. Also, perceived behavioural control at T1 did not influence condom use at T2 after controlling for the effect of baseline intention. The possibility of reciprocity was also tested for all relations and significant results were found. The moderation effect of perceived behavioural control on the relationship between intention and condom use was not significant. The differences in age, gender and partnership status were taken into account in the analyses.     

Improving postswitch performance in the dimensional change card-sorting task: the importance of the switch and of pretraining by redescribing the test cards

The dimensional change card-sorting task (DCCS) is used to assess the executive abilities of young children. Typically, 3-year-olds have difficulty in performing this task. However, the exact nature of this difficulty is still being debated. In the standard DCCS, children need to sort, for example, test cards with a blue flower or a red car into two boxes marked with the target cards. The 3-year-olds commonly have pronounced difficulty in switching from one sorting criterion (e.g., color) to another (e.g., shape). Here two experiments with 3-year-olds showed that making the transition between the sorting criteria more distinct improved performance significantly. This was achieved by taking away the target cards for a brief time period, asking a question irrelevant to the task, and pretraining the children by redescribing the test cards.     

全科医学临床诊疗中的决策

临床诊疗的每个步骤,几乎都涉及如何决策的问题.医生应该将患者的利益放在首位,告诉患者拟采取的这些步骤其效果、风险及花费,让患者作出最终的决定.全科医学的精髓是“以人为本”,全科医师更应该帮助患者决策、让患者决策.而全科医疗的特点也决定了必须如此和可能如此.     

合理用药中用药时间的研究

学步期焦虑影响5岁幼儿创造力：一般认知和掌握动机的链式中介作用

儿童早期焦虑是一种常见的心理卫生问题, 影响个体中央执行功能的发展, 而个体中央执行功能所表现的认知能力的发展通常反映出个体创造性问题解决的过程。本研究采用追踪研究设计, 探讨了学步期儿童焦虑对其学龄前期创造力的长时影响及其潜在作用机制。来自北京的96个家庭(男孩42名, 女孩54名)参与了本研究。在儿童1岁和2岁时, 母亲填写中国版《12~36月龄幼儿情绪社会性评估量表》和家庭基本信息调查表。在儿童2岁时, 采用贝利婴幼儿发展量表评估幼儿的一般认知能力; 在儿童3岁时, 母亲报告儿童掌握动机情况; 在儿童5岁时, 采用托兰斯活动与动作创造性思维测验评估儿童的创造力。研究结果表明：(1)儿童学步期焦虑(广泛性焦虑和分离焦虑)可以显著负向预测其5岁时的创造力; (2)一般认知能力和掌握动机在儿童学步期焦虑(广泛性焦虑和分离焦虑)和学前期创造力之间的链式中介作用成立; (3)儿童学步期广泛性焦虑还可以通过直接负向预测掌握动机, 从而对其5岁创造力的表现产生消极影响。

Association between the Five Factor personality traits and perceived stress: is the effect mediated by general self-efficacy?

Abstract

Ill-health resulting from chronic stress is influenced by personality traits leading to different ways of appraising and coping with life's daily hassles. Using a large population sample the study aimed to investigate possible associations between perceived stress and the personality dimensions of neuroticism, extroversion, openness, agreeableness, and conscientiousness, and to explore the role of general self-efficacy (GSE). A population-based cross-sectional study was conducted at the Research Centre for Prevention and Health, Denmark, in 2006–2008. Men and women (N=3471) aged 18–69, were randomly sampled in the suburbs of Copenhagen. We used the NEO Five-Factor Inventory (NEO-FFI), Cohen's Perceived Stress Scale and the General Self-Efficacy Scale. Negative associations were found between perceived stress and extroversion, conscientiousness, agreeableness, and openness – the latter initially non-significant – whilst neuroticism had a positive association. The associations with agreeableness and openness became positive and significant, respectively, when GSE was included. All five personality-stress models were mediated by GSE, with extroversion and conscientiousness having the strongest mediating effect. The strongest stress-association was found for neuroticism. GSE was shown to change the impact and interpretation of the personality dimensions on perceived stress. These results indicate that GSE is an important factor to consider in the link between personality and perceived stress.     

The Effects of Parental Tobacco and Marijuana Use and Personality Attributes on Child Rearing in African-American and Puerto Rican Young Adults

We assessed the effect of the interrelationship of mothers’ and fathers’ tobacco and marijuana use with their personality attributes on some of their child rearing behaviors. We used a longitudinal design to analyze the data of 258 males and females who were seen four times over a 13-year period from early adolescence through young adult parenthood. Thirty-one percent of the multiple regression analyses revealed significant interactions between the effect of tobacco or marijuana use and a personality attribute on child rearing. The majority of these significant interactions suggested that protective personality characteristics were offset by substance use risks resulting in less adequate child rearing. If these results are substantiated in an experimental intervention, it suggests that having resilient personality attributes does not protect against the negative effects of tobacco or marijuana use on child rearing.     

The relationship between the shape of the mental number line and familiarity with numbers in 5- to 9-year old children: evidence for a segmented linear model

This experiment aimed to expand previous findings on the development of mental number representation. We tested the hypothesis that children's familiarity with numbers is directly reflected by the shape of their mental number line. This mental number line was expected to be linear as long as numbers lay within the range of numbers children were familiar with. Five- to 9-year-olds (N=78) estimated the positions of numbers on an external number line and additionally completed a counting assessment mirroring their familiarity with numbers. A segmented regression model consisting of two linear segments described number line estimations significantly better than a logarithmic or a simple linear model. Moreover, the change point between the two linear segments, indicating a change of discriminability between numbers, was significantly correlated with children's familiar number range. Findings are discussed in terms of the accumulator model, assuming a linear mental representation with scalar variability.     

From the Roots of Psychosocial Practice-Therapeutic Use of Self in the Classroom: Practical Applications for Occupational Therapy Faculty

The roots of occupational therapy stem from psychosocial practice and embrace concepts of humanism, client-centered practice and therapeutic use of self. These concepts are integral to both clinical and academic settings. As the profession has moved toward graduate level education, increased numbers of non-traditional students are entering the field. Models of teaching that incorporate principles of active learning and therapeutic use of self within the classroom provide a consumer-learner-based model of education that is uniquely suited to students of diverse backgrounds, lifestyles, and educational needs. This article presents a brief overview of andragogical principles and the development of the student-faculty relationship. Mosey's concepts of conscious use of self are introduced as a means by which positive faculty-student relationships can be formed in order to enhance student learning and educational outcomes.

Varieties of Linear Calculi

A uniform calculus for linear logic is presented. The calculus has the form of a natural deduction system in sequent calculus style with general introduction and elimination rules. General elimination rules are motivated through an inversion principle, the dual form of which gives the general introduction rules. By restricting all the rules to their single-succedent versions, a uniform calculus for intuitionistic linear logic is obtained. The calculus encompasses both natural deduction and sequent calculus that are obtained as special instances from the uniform calculus. Other instances give all the invertibilities and partial invertibilities for the sequent calculus rules of linear logic. The calculus is normalizing and satisfies the subformula property for normal derivations.     

Do differences in general trust explain cultural differences in dispositionism?1

Abstract: It has been suggested that Westerners are more inclined than Easterners to endorse dispositionism. To help explain what produces this cultural difference, I examined the responses of Japanese and American students to determine whether levels of general trust, which is the expectation of benign or cooperative behavior based on the goodwill of another person (Yamagishi & Yamagishi, 1994), would matter. As predicted, in accounting for either a prosocial or deviant behavior, high trusters were more likely than low trusters to show dispositionism on all three measures (dispositional attribution, trait inference, and behavioral consistency), whereas cultural differences in dispositionism almost vanished. This tendency was found regardless of the desirability of behaviors.

Family Protection and Prevention of Alcohol Use Among Hispanic Youth at High Risk

Research regarding prevention strategies for Hispanic youth stress the importance of family interventions because of the particular importance of family as a protective factor within the Hispanic community. Starting in 1995, the Center for Substance Abuse Prevention conducted the National Cross-Site Evaluation of High Risk Youth Programs, a 5-year drug and alcohol prevention study with a sample of approximately 10,500 youth, including nearly 3,000 Hispanic youth. Youth were surveyed regarding their alcohol use patterns and risk and protective factors, with several measures of family relationships, including family connectedness, family supervision, and parental attitudes toward their child's alcohol use. Analyses indicate that family factors are highly linked to alcohol use among Hispanics, particularly among Hispanic females. Longitudinal growth curve analyses indicate that improving the connections that young Hispanic females have to their parents can have positive long-term effects on delaying or reducing their alcohol use. This evaluation was conducted under the direction of Dr. Soledad Sambrano, Ph.D. of the Center for Substance Abuse Prevention under contract #2777-95-5002 with EMT Associates, Inc. and ORC Macro.
