COVID-19 has altered adolescents' opportunities for developing and strengthening interpersonal skills and proficiencies. Using data from adolescents in Italy, the United States, and the United Kingdom, we examined the relation between internalizing symptoms assessed pre-pandemic or when pandemic-related restrictions were lifted (Time 1) and associated internalizing symptoms during a subsequent restrictive pandemic period (Time 2). Across all 3 countries, we found significant and consistent effect sizes in the relation between Time 1 and Time 2 internalizing symptoms. We further examined the direct and moderating impact of self-efficacy and contextual supports for adolescents' internalizing symptoms. Higher self-efficacy was associated with lower levels of internalizing symptoms at Time 2 in all 3 countries. Additionally, the relation between Time 1 and 2 internalizing symptoms was buffered by regulatory self-efficacy and peer support in Italy, but in the U.S., higher levels of general self-efficacy instead had an exacerbating effect on the relation between Times 1 and 2 internalizing symptoms. Results are discussed in the context of utilizing cross-national datasets to examine similarities in adolescent well-being over time and in the face of varying government responses to the pandemic. 相似文献

A study was designed to compare several variables of Manpower Development Training Act (MDTA) clients who dropped out of the program with those of clients who completed the program. A random sample of application cards was drawn for individuals enrolled in MDTA adult classes in Milwaukee, Wisconsin. Trainees who completed the program were more likely to be married, older, characterized by a more stable employment history prior to entering the program, and slightly more educated than were program dropouts. Clients who completed the program versus those who did not were not significantly different on the following variables: (1) sex; (2) counseling versus no counseling; (3) race; and (4) client reported physical disability. 相似文献

3 groups of university freshmen took the SAT-V before and after a course in Accelerated Reading. The mean post-test scores for 2 groups increased slightly less than 10 points, while the mean post-test score for the third group decreased significantly. It is concluded that for the type of students used in this study, a course emphasizing speed and accuracy of reading is not of value in increasing scores on the verbal part of the Scholastic Aptitude Test. 相似文献

An adaptation-level model for memory was tested by interpolating different weights between the standard and comparison weights. The results suggest that the model should be modified to account for the general tendency to use alternative categories of judgment with equal frequency. In terms of the modified model, memory for the standard shifts toward the value of the interfering stimulus, the magnitude of shift being proportional to the difference between the interfering stimulus and the value the memory would otherwise have had. 相似文献

The structure of a course entitled Family Therapy with Major Psychopathology taught annually in the Mercer University Graduate Marriage and Family Therapy Program is presented. An epistemological presentation regarding the interface of psychiatric nosology and family systems assessment is discussed. Methods of diagnosing and assessing dysfunctional family systems are presented and training in individual psychiatric nosology is discussed, with particular attention given to family systems dysfunction as an etiological factor in the development of individual psychopathology. Learning techniques are discussed including lecture, discussion, case presentations, readings, and testing methods. 相似文献
