Although message‐production theories often assume that goals behave dynamically to direct communication behavior, few studies consider the interconnectedness of goals and behavior throughout interactions. Here, the interrelationship of communication goals and tactics was examined through a sequential analysis of 47 conflict interactions between close friends or dating partners. It was posited that for both the initiators and resistors in a conflict, the importance of relational or other‐identity goals would be associated with the use of integrative tactics and the importance of instrumental or self‐identity goals would be related to the use of distributive tactics. We examined these predictions within and across partners. Analyses indicated that for both conflict initiators and resistors, the importance of a combination self/instrumental goal predicted the use of distributive tactics and the importance of an other‐identity goal lead to partner‐oriented tactics. For resistors, the importance of an instrumental goal was associated with the use of distributive tactics and the importance of a combination identity/relational goal was aligned with issue‐oriented tactics as well. Across partners, several significant patterns between one partner’s use of distributive or integrative tactics and the other partner’s goals were observed. Implications of the results for understanding conflict and message production are discussed. 相似文献

The present study investigates the prevalence of adolescent eating disorders across gender, cultural groupings, and socioeconomic status. The Eating Attitudes Test, the Binge-Eating Questionnaire, and a demographic questionnaire were administered to students at two high schools. The results indicate a high rate of eating disorders in a nonclinical adolescent population. The rates for binge eating are comparable to those found in studies of college students--found at a younger age. With regard to SES, cross-cultural and gender findings, it is clear that eating disorders cross socioeconomic class and ethnic groups, and have a higher rate of occurrence in males than previously reported. Given such high rates of eating problems in a nonclinical population, the issue of prevention and early detection must be addressed. Additionally, more specific information on male eating disorders is needed. 相似文献

As part of a large survey of addictive behavior in high school students, 43% of a sample of 278 (26% of the males, 57% of the females) scored above the cutoff point set by Overeaters Anonymous on their scale for assessing compulsive overeating. While this at-risk group did not report poorer general adjustment, health, or school achievement than did the students not at risk, they did significantly more often perceive their life quality and relationship with the person closest to them as less positive. The at-risk subsample indicated the defensive effectiveness of overeating in their significantly more frequent report of dissociative experiences while eating, and less severe ratings of insecurity, worrying, and daydreaming. One of the most salient findings was the at-risk students' more frequent report of addictive problems in their parents (overeating, alcohol and drug use, and gambling). 相似文献

The study examined physical symptoms and health service utilization of subjects high or low on a measure of the tendency to experience stress somatically and high or low on a measure of current stress. High somatic responders reported greater numbers of symptoms than low somatic responders regardless of stress level. However, high somatic responders who were experiencing high levels of current stress reported significantly more symptoms than high somatic responders who were experiencing low levels of stress. These findings indicate that somatic response to stress reflects both a general tendency to focus on physical symptoms, and a specific tendency to focus more on physical symptoms when under stress. Analysis of health service records indicated that high somatic responders had more visits prompted by symptoms than low somatic responders, but did not differ in frequency of health service visits designed to maintain health. The findings further clarify the relationship between somatic response to stress, physical symptoms and health service use. 相似文献

This study examined the vulnerability of the Michigan Alcoholism Screening Test (MAST), a widely used, direct alcohol inventory, to positive dissimulation. An earlier study by developers of the MAST suggested that most alcoholics were unable to alter their scores and thereby avoid detection by the instrument. But closer examination indicated that a standard scoring procedure was not employed. This study examined the ability of alcoholics to avoid detection by the MAST when using a standard scoring procedure. As predicted, alcoholics readily manipulated their MAST scores and avoided detection when so motivated. These results are discussed, indications and contraindications for use are included, and recommendations regarding future research are made. 相似文献

This study examined the relationship between two prominent measures of egocentrism, Enright's Adolescent Egocentrism Scale (AES) and Elkind's Imaginary Audience Scale (IAS), in a sample of 458 adolescents, between 10 and 15 years old. Both correlational and factor analyses indicated that the two measures assess distinctly different phenomena. As predicted, IAS scores were correlated with self-reported levels of shyness, nervousness, and social skills. These results provide partial evidence for the validity of the IAS as a measure of self-consciousness, though not necessarily egocentrism per se. The validity of the AES was not examined. 相似文献
