  Self-Reported Anxiety in Children and Adolescents: A Three-Year Follow-Up Study

  摘要：

  Anxiety may be more transient in children and adolescents than in adults. The present study involves a longitudinal design enabling the investigation of the continuity/discontinuity of self-reported anxiety in children and adolescents. A sample of 68 children was followed over 3 years. Results indicate that, on the whole, self-reported anxiety decreased over time. This was true for overall anxiety and its sub-types, with the exception of social concerns/concentration, which did not decrease over time. Consistent with past research involving normal fear, girls and younger children were found to score higher on anxiety than boys and older children did. However, those groups scoring higher at inception also demonstrated the most marked decreases over the 3-year period. In addition to the changes found over time, the data indicated continuity in anxiety such that levels of anxiety at inception were significant predictors of follow-up anxiety, although only a small amount of variance was shared. The authors concluded that adult models of anxiety cannot be applied to youth and that future research should investigate the contribution of contextual factors to the development of anxiety in children.

  first, on treatment with acids, the methylium dye 2′a, which absorbs far into the NIR region (λmax = 1100 nm). The higher members 2b,c (n = 2,3) of the carbinol series yield by acidic treatment only N-protonated methylium dyes 2″′b,c. The different behavior is due to a decreasing donor–acceptor interaction with increasing D–A distance. The N-protonated methylium salts 2″′a–c show long-wavelength absorptions
