A high proportion of positive responses was obtained from students who participated in three different types of pre-college orientation programs. Small group approaches consistently elicited more favorable responses than assemblies or large groups. Greater faculty involvement resulted in participants' noting an increased academic emphasis. Participants believed they had benefited in some way from programs which varied considerably as to length, activities, organization, and purposes.  相似文献

To explore the usefulness of various structural Rorschach data in identifying psychiatric inpatients with symptoms of depression, 54 adult inpatients were administered a Rorschach. Results indicated that the Comprehensive System, Rorschach Depression Index did not identify many of these individuals as depressed, but did identify most of the extratensive depressed individuals. Each variable included in the Depression Index and other potential, Rorschach correlations of depression were also investigated. Most of them were found to occur more often among these depressed patients than among nonpatients. Furthermore, adding other variables and using more liberal cutoffs may result in more accurate identification of patients with depressive symptoms.  相似文献

MMPI profiles of female adolescents hospitalized on a general pediatrics floor following a suicide attempt were compared to a control group of medically hospitalized, female adolescents referred for psychiatric evaluation. The suicide attempters had only a lower score on the K scale when compared to the control group. Results do not suggest that a single MMPI profile differentiates suicide attempters from a comparison group of adolescents with emotional difficulties. Implications of these findings are discussed.  相似文献

A comparison of two measures of egocentrism   总被引:1,自引:0,他引:1  
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
