This research examined the psychological underpinnings of concern for national symbols and ritualistic‐ceremonial activities or “symbolic involvement.” We propose and test a distinction between symbolic and “instrumental” involvement or concern for the functionality of national institutions and their capability to provide instrumental benefits to citizens. Items comprising the two constructs were found to be empirically distinct, evidenced by statistically reliable and orthogonal dimensions in exploratory factor analysis. Moreover, evidence based on divergent patterns of relations with various forms of national membership indicates that symbolic and instrumental involvement are rooted in distinct motivational concerns related to identity expression and object appraisal, respectively. These findings suggest that national symbolism evokes a psychological attachment to the nation as an abstracted social entity, but not as a concrete functional system.  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

A time-limited dynamic approach to adolescent inpatient group psychotherapy   总被引:1,自引:0,他引:1  
T J McGuire 《Adolescence》1988,23(90):373-382
In response to sharply curtailed lengths of stay of adolescents in an inpatient psychiatric program, new therapeutic modalities need to be implemented. A time-limited dynamic approach to adolescent inpatient group psychotherapy is presented. The model integrates psychoanalytic and crisis theory into a group format. The primary focus in this model is upon resolution of problematic interpersonal interactions as they are related to the current crisis state. The group process, as related to the adolescent, involves three phases. These include an initial intake phase, which incorporates an ego-functioning assessment; a second or middle phase which focuses on making actions ego-alien; and the termination phase, which incorporates the learning experience and how it relates to the resolution of precipitators of the admission.  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
