Alcohol consumption is the leading risk factor for morbi‐mortality in many Latin American Countries. However, epidemiologic studies are relatively scarce. Among factors such as limited research capacity, disciplinary traditions and an emphasis on psychopathology within the field of psychology, have been postulated to account for this. The aim of this article is to review epidemiologic research on alcohol in Spanish Speaking Latin American Countries, and to measure the contribution of psychology to the field. A systematic search was performed in English and Spanish using regional and international data bases. We identified 269 articles. Most focused on consumption patterns in youth, with samples from a single school and using a variety of measures. With the exception of multinational efforts like Emergency Room Collaborative Alcohol Analysis Project or those supported by World Health Organization/Pan American Health Organization, studies reviewed reflected little cross country collaboration. Mexico accounted for most of the productivity, while many countries had very few or no articles. Most research was performed by health science researchers with a small contribution from psychology, but which increased significantly over time. The results of this review provide a broad identification of patterns regarding epidemiologic research on alcohol, and demonstrate the need for national scientific policies to promote research on public health topics.  相似文献

In this article, we assume an interdisciplinary approach to the study of why and how people transpose political considerations to their lifestyles. Our aims are threefold: to understand the meanings and perceptions of people engaged in lifestyle politics and collective action; to examine the motives guiding individual change; and to explore the linkage processes between lifestyle politics and collective action. Identity process theory is considered as a lens to examine the processes and the motives of identity via a thematic analysis of 22 interviews. This study combined interviews with people seeking social change through their lifestyles with interviews with members of action groups and social movements. We found that each participant's identity is guided by identity motives such as distinctiveness, continuity, and psychological coherence. Besides, lifestyle politics is evaluated as an effective way to bring about social change, depending on the individual experience of perceived power to bring about change through collective action. Overall, lifestyle politics states the way in which the participants decided to live, to construct their identities, and to represent their beliefs about the right thing to do. Lifestyle politics complements collective action as a strategy to increase the potential of bringing about social change. The implications of this research are discussed in relation to the importance of understanding the processes of identity and lifestyle change in the context of social, environmental, and political change.  相似文献

Background and Objectives: Diminished heart rate variability has been found to be associated with high anxiety symptomatology. Since adolescence is the period of onset for many anxiety disorders, this study aimed to determine sex- and anxiety-related differences in heart rate variability and complexity in adolescents.

Methods: We created four groups according to sex and anxiety symptomatology: high-anxiety girls (n?=?24) and boys (n?=?25), and low-anxiety girls (n?=?22) and boys (n?=?24) and recorded their cardiac function while they performed regular school activities. A series of two-way (sex and anxiety) MANOVAs were performed on time domain variability, frequency domain variability, and non-linear complexity.

Results: We obtained no multivariate interaction effects between sex and anxiety, but highly anxious participants had lower heart rate variability than the low-anxiety group. Regarding sex, girls showed lower heart rate variability and complexity than boys.

Conclusions: The results suggest that adolescent girls have a less flexible cardiac system that could be a marker of the girls’ vulnerability to developing anxiety disorders.  相似文献

This paper outlines the development of pan European systemic thinking and practice. This development has been enabled and supported with the establishment of the European Family Therapy Association (EFTA). EFTA has evolved over the last decade from an organisation of individual members to an organisation of organisations—representing also national associations of family therapy and family therapy training institutes across 28 European countries. There are three sections to this paper: (1) a brief summary of the development of family therapy practice in Europe; (2) a brief summary of the work of the national associations of family therapy in EFTA; and (3) a brief summary of current concerns of some senior family therapists and family therapy trainers within the EFTA organisation.  相似文献

Havik, M., Jakobson, A., Tamm, M., Paaver, M., Konstabel, K., Uusberg, A., Allik, J., Ööpik, V. & Kreegipuu, K. (2012). Links between self‐reported and laboratory behavioral impulsivity. Scandinavian Journal of Psychology 53, 216–223. A major problem in the research considering impulsivity is the lack of mutual understanding on how to measure and define impulsivity. Our study examined the relationship between self‐reported impulsivity, behavioral excitatory and inhibitory processes and time perception. Impulsivity – fast, premature, thoughtless or disinhibited behavior – was assessed in 58 normal, healthy participants (30 men, mean age 21.9 years). Self‐reported impulsivity as measured by Adaptive and Maladaptive Impulsivity Scale (AMIS) and behavioral excitatory and inhibitory processes as measured by Stop Signal Task were not directly related. Time perception, measured by the retrospective Time Estimation Task, was related to both. The length of the perceived time interval was positively correlated to AMIS Disinhibition subscale and negatively to several Stop Signal Task parameters. The longer subjects perceived the duration to last, the higher was their score on Disinhibition scale and the faster were their reactive responses in the Stop Signal Task. In summary our findings support the idea of cognitive tempo as a possible mechanism underlying impulsive behavior.  相似文献

Two theoretically based parent training programs, delivered in real-world settings by the social services, were examined in this randomized controlled trial for effectiveness in reducing adolescents’ antisocial behavior and substance use. Two hundred and thirty-seven (237) adolescents in ages between 12 and 18 and their parents were assigned to one of two programs or to a wait-list control condition. The programs were the nine weekly group sessions program Comet 12–18 (Swedish Parent Management Training Program) and the six weekly ParentSteps (Swedish shortened version by Strengthening Families Program 10–14). Outcome measures were antisocial behavior, substance use, and delinquency, and psychosocial dysfunction. Data based on adolescents’ and parents’ ratings of the adolescents’ problem behavior at baseline and 6 months later were analyzed with repeated measures ANVOA, Logistic regression, and Kruskal–Wallis H test. The results showed that parents’ ratings of adolescents’ antisocial behaviors decreased significantly over time, but no time by group effect emerged. No program effects were found in the adolescents’ self-reported antisocial behavior, delinquency, or psychosocial functioning. A threefold risk of illicit drug use was found in both intervention groups. The results suggest that neither Comet nor ParentSteps had beneficial effects on adolescent’s antisocial or delinquent behavior, or on alcohol use. The only significant group difference found was a threefold risk of drug use in the intervention adolescents at follow-up, but for several reasons this finding should be interpreted with caution.

Research has consistently shown that endorsing a religion or spirituality is to some extent related to one’s well-being. Common studied explanations tap into the social and cognitive aspects of religion and spirituality. The present research aims at understanding how religiosity and spirituality exert their impact on well-being and investigates the role of a surprisingly neglected mechanism: positive emotions. Two cross-sectional studies using a quantitative approach are presented. In two different contexts (churchgoers in a European country and US university employees interested in meditation), results showed that the relation between religion (Study 1), spirituality (Study 2) and well-being is mediated by positive emotions. Distinguishing between more and less relevant positive emotions in a religious/spiritual context, it was found that the effect was mediated by self-transcendent positive emotions (awe, gratitude, love, and peace) but not by other positive emotions (amusement and pride).  相似文献

Both the acquisition and the extinction of memories leave short- and long-term mnemonic traces. Here, we show that in male Wistar rats, the short-term memory for a step-down inhibitory avoidance task (IA) is resistant to extinction, and that its expression does not influence retrieval or extinction of long-term memory. It has been known for some time that short- and long-term inhibitory avoidance memory involve separate and parallel processes. Here we show that, instead, short-term extinction of IA long-term memory is the first step towards its long-term extinction, and that this link requires functional NMDA receptors and protein synthesis in the CA1 region of the dorsal hippocampus at the time of the first CS-no US presentation.  相似文献

The present study investigated the receptiveness of speakers toward conversational partners in dialogues by comparing duration of response latencies in both Compromise and Debate conditions. 12 dyads of speakers holding opposing opinions participated in a 15-min. dialogue. Six dyads in the Compromise condition reached a conclusion through discussion and consideration of the partner's opinion. The six dyads in the Debate condition imposed their opinion on the conversational partner. Analysis indicated that in compromise dialogues, the response latencies of the conversational partners become similar over the time course, while in debate diaogues, the response latency does not become similar, suggesting that speakers having a receptive attitude adjust their response latencies to match the partner's. The role of congruence of response latencies in dyadic communication was discussed.  相似文献
