During June 2000-May 2001, the American Cancer Society conducted a randomized trial of telephone counseling among more than 3,500 current smokers who called to seek assistance in quitting. All eligible callers were randomized to receive either self-help booklets through the mail or booklets and up to 5 sessions of telephone counseling. Approximately 12% (420/3,522) of study participants were 18-25 years of age. Using intent to treat analyses, 3- and 6-month quit rates among both younger and older smokers were significantly higher among those who received telephone counseling than among those who received self-help booklets only. Three-month rates were 20% versus 9% for 18-25 year olds and 15% versus 10% for older adults. Results indicate that younger smokers can benefit from telephone counseling. 相似文献

Il y a plus d'une décennie, Ashford, Lee, and Bobko (1989) ont développé un outil de mesure standard permettant évaluer des niveaux individuels d'insécurité au travail. Les années suivantes, des chercheurs se sont demandé si la totalité des mesures composant cet instrument était nécessaire. Nous avons donc examiné l'utilité des différentes dimensions du test multidimensionnel de l'Insécurité au travail de Ashford et al. (1989) aux Etats Unis et en Chine, en éprouvant et élargissant les conclusions antérieures. Nos résultats suggèrent qu'éliminer les dimensions "caractéristiques du travail" et "impuissance" de l'instrument multidimensionnel initial est prématuré dans les deux cultures. D'autres recherches s'avèrent donc nécessaires pour déterminer l'utilité de cet outil dans sa version complète. Les implications de nos résultats sont discutées.
Over a decade ago, Ashford, Lee, and Bobko (1989 ) developed a standard measure for those interested in assessing levels of individual job insecurity. In ensuing years, some researchers have questioned whether the entire measure is necessary. We examined the usefulness of the components of Ashford et al.'s (1989 ) multidimensional measure of job insecurity in both the United States and China, as well as replicating and extending prior findings regarding antecedents and consequences. Our results suggest that the call to eliminate job features or powerlessness from the fully composite measure of job insecurity is premature in both cultures. We call for more research on the utility of the fully operationalised measure. Implications of our findings are discussed. 相似文献

Four experiments were conducted to evaluate whether focal attention can be guided by an analysis of the emotional expression in a face. Participants searched displays of 7, 11, 15, and 19 schematic faces for the location of a unique face expressing either a positive or a negative emotion located among distractor faces expressing a neutral emotion. The slopes of the search functions for locating the negative face were shallower than the slopes of the search functions for locating the positive face (Experiments 1A and 2A). When the faces were inverted to reduce holistic face perception, the slopes of the search functions for locating positive and negative faces were not different (Experiments 1B and 2B). The results suggest that the emotional expression in a face can be perceived outside the focus of attention and can guide focal attention to the location of the face. 相似文献
