Terrorism and cardiovascular responses to acute stress in children.

A number of studies have considered whether background stress affects cardiovascular responses to acute stress tasks. The present study considers the effect of a potent background stressor with a clear onset, namely the terrorist attacks on September 11, 2001. Specifically, the authors investigated differences among 9.5-year-old children tested before (N = 30) and then following (N = 20) the 9/11 attacks. In addition, a majority of these children (N = 37) were retested approximately 1 year later (i.e., before and after 9/11/2002). Children tested directly following 9/11/2001 exhibited significantly greater stroke volume and cardiac output responses to acute stress tasks compared with their responses 1 year later, and this change in reactivity differed significantly from the change in reactivity exhibited by children tested before 9/11/2001 and again 1 year later. These results suggest that a potent background stressor can temporarily heighten some children's cardiovascular responses to subsequent acute stressors.     

Development and Validation of the Chinese Creative Writing Scale for Primary School Students in Hong Kong

The 13-item Chinese Creative Writing Scale was expanded and modified from the Carlson Originality Scale to assess creativity elements in compositions of primary school students in Hong Kong. The content validity was endorsed by a small expert panel. Results show that the scale has excellent interrater reliability (.90 to .98), and moderate to good internal consistency. Exploratory factor analysis shows that the three factors (flexibility, originality, and fluency) accounted for 59.1% of the variability, which is consistent with the design of the scale. The scale can also be used as an outcome measure for assessing the effectiveness of strategies which aim at enhancing creativity of students. With minor modifications, the scale can also be applied in mainland China, Taiwan, and Chinese societies elsewhere in the world.
