La construcción situacional en la ingesta alcohólica

RESUMEN

En la primera parte de este artículo se elabora un modelo de “construcción situacional de ingesta alcohólica”; en la segunda parte se aplica este modelo al estudio de la influencia de la publicidad sobre la ingesta alcohólica. El presupuesto básico de esta investigación era que mientras el sistema perceptivo es diferentemente afectado por los estados momentáneos, los estados experimentales o la propaganda sufrida, la estructura abstracta reflejada por la taxonomía situacional es escasamente afectada por la influencia de las variables experimentales, en este caso, por la propaganda alcohólica recibida. Los resultados encontrados manifiestan que la construcción de las situaciones de ingesta alcohólica está, al menos, modelada por los factores publicitarios, y que esta influencia es mayor cuanto menos es la edad de quien recibe la información.     

Do men with excessive alcohol consumption and social stability have an addictive personality?

The existence of an "addictive" personality has been extensively debated. The current study investigated personality in male individuals with excessive alcohol consumption (n=100) in comparison to a population-based control group (n=131). The individuals with excessive alcohol consumption were recruited by advertisements in a regional daily newspaper and controls from a population based Swedish Twin Registry. Personality was assessed by the Karolinska Scales of Personality (KSP). Comparisons were made with normative data. Furthermore, by using a multivariate projection-based approach (Principal Component Analysis; PCA), hidden structures of traits and possible relationships among the individuals with excessive consumption and the controls was investigated. The individuals with excessive alcohol consumption as well as the controls had mean values within the normative range in all scales of the KSP. Moreover, the PCA analysis revealed no systematic between-group separation. Taken together, this result demonstrates that male individuals with excessive alcohol consumption do not have a personality different from that of a general population, which supports the notion of no "addictive personality".     

Brain functions associated with verbal working memory tasks among young males with alcohol use disorders

This study aimed to investigate the differences in brain functions during verbal working memory between individuals with alcohol use disorders (AUD) and normal controls. fMRI was used to scan brain activations associated with verbal working memory while participants performed 2-back and 0-back tasks. A total of 21 young male college students participated in the study. Eleven of those who clinically met the criteria for AUD were assigned to the AUD group, whereas ten demographically similar subjects who were social drinkers but not AUD were assigned to the normal control group. The AUD group showed less activation in bilateral frontal and precentral, left superior temporal, left superior parietal, and left cerebellar cortex during the 2-back task relative to 0-back task compared to the normal control group. In contrast, the control group showed less activation only in the right uncus than the AUD group. These results suggest that subjects with AUD present abnormality in brain functioning during verbal working memory.     

环境和个体因素与青少年饮酒行为的关系

选择湖南长沙三所中小学的681个学生为被试,考察青少年饮酒行为的特点及环境和个体影响因素的预测作用。结果发现:(1)过去的一个月中,31%的青少年曾有过饮酒行为,12.7%和8.5%的青少年有过大量饮酒和醉酒行为。男生、学习成绩中下者饮酒行为更多;(2)青少年饮酒行为与最好同伴和普通同学的饮酒行为、学校周围的饮酒环境呈显著正相关,与最好同伴和普通同学的饮酒态度、青少年自身的饮酒态度和饮酒拒绝效能感呈显著负相关;(3)同伴、学校环境因素和饮酒态度可以直接预测青少年的拒绝效能感,同时,同伴、学校环境因素又通过饮酒态度和拒绝效能感间接地预测青少年的饮酒行为。     

Power of being present: the role of mindfulness on the relation between men's alcohol use and sexual aggression toward intimate partners

The primary aim of this investigation was to examine the association between men's level of mindfulness and histories of alcohol consumption and sexual aggression toward intimate partners. Participants were 167 heterosexual drinking males who completed self‐report measures of mindfulness, frequency and quantity of alcohol consumption during the past 12 months and sexual aggression against intimate partners during the past 12 months. Results indicated that a history of consuming larger amounts when drinking was associated with more frequent sexual coercion/aggression among men who reported low, but not high, levels of mindfulness. However, drinking more frequently by itself was not associated with more frequent sexual coercion/aggression. These results support the attention‐allocation model and suggest implications for future intervention research aimed at reducing alcohol‐related aggression. Aggr.

Men's likelihood of sexual aggression: the influence of alcohol,sexual arousal,and violent pornography

Previous research findings have indicated that both alcohol intoxication and violent pornography exposure may contribute to increased sexual aggression by men. This study used an experimental paradigm to examine the effects of a moderate alcohol dose, alcohol‐related beliefs, and victim response on men's self‐reported likelihood of committing sexual aggression. A community sample of male social drinkers (N=84) participated in an experiment in which they read an eroticized rape depiction after completing an alcohol administration protocol. The stimulus story varied whether the victim, who initially expressed unwillingness to engage in sexual activity, expressed pleasure or distress in response to the man physically forcing her to perform several explicit sex acts. A path analytic model illustrated that participants' self‐reported likelihood of behaving like the sexual aggressor in the story was directly related to their own sexual arousal. Heightened sexual arousal was reported by participants who had consumed alcohol, those who read the victim‐pleasure story, and those who believed that drinking women are sexually vulnerable. Results suggest that sexual arousal to violent pornography, as influenced by acute alcohol intoxication and other factors, may be an important component of men's perceptions of their own sexual aggression likelihood.

An investigation of the correlations between aggression,impulsiveness, social problem‐solving,and alcohol use

Impulsivity has been shown to predict aggression and heavy drinking in males, and poor social problem‐solving has been identified as a potential mediating variable in this relationship. We set out to investigate the inter‐relationships among impulsiveness, social problem‐solving, aggression, and alcohol use in a non‐offender sample of British males (N=70). Of our proposed relationships, only two were significant: higher impulsivity was related to poorer social problem‐solving, and poorer social problem‐solving was related to greater aggression. Combining impulsivity and social problem‐solving indicated that poor social problem‐solving, not impulsivity, was what exerted the influence over aggression in this sample. Impulsivity perhaps presents an obstacle to learning in the early developmental years, and the legacy of poor problem‐solving is what later contributes to aggression. Aggr.

Reactions to Organizational Alcohol Testing and Treatment Programs

We used organizational justice theory to explore reactions to employer-sponsored alcohol testing and alcohol treatment policies among a sample (N = 1,777) of the employed public in a western state. Level of alcohol use and safety-sensitivity of the job were related to the perceived fairness of alcohol testing. In addition, voluntary treatment policies were rated more positively than coerced or monitored policies in terms of fairness and organizational attractiveness. Alcohol use moderated the effects of treatment policy on perceived fairness and organizational attractiveness, although the effect sizes were small. These results support the use of organizational justice theory to explain reactions to organizational alcohol testing and treatment and provide a basis for future research in this area.     

Women,alcohol, self‐concept and self‐esteem: A qualitative study of the experience of person‐centred counselling

This study explores the self‐concept and self‐esteem of women with alcohol problems from a client perspective, and relates the findings to person‐centred theory and practice. Eight women with severe and long‐standing alcohol problems, who had received person‐centred counselling, were interviewed in relation to their sense of self over time. The data were analysed using grounded theory methodology, resulting in the emergence of five key categories. Examples from the interviews are used to illustrate the complex relationships between life experience, self‐concept, self‐esteem and drinking. The possible significance of the findings for counsellors working with this client group is discussed.
