The purpose of this study was to determine the efficacy of Circle of Security (COS) on preschool children & apos; s attachment and well-being. 48 mothers with children & apos; s age 4 to 6 year were randomly selected through cluster sampling and randomly assigned to experimental and control groups (24 mothers and child in each group). Then the experimental group received 20 weekly COS sessions in the center of preschool. The attachment Q-set and Preschool children well-being questionnaire (PCWQ) were used as the pretest, post-test and in the course of follow-up. Results of Multivariate Analysis of Covariance (MANCOVA) showed that the mean scores of attachment, in the experimental group, was significantly greater than the control group in post-test (P = 0.000) and follow-up (P = 0.002). Results also showed that the scores of well-being in experimental group was significantly greater than the control group in post-test (P = 0.006) and follow–up (P = 0.018). The finding of the study emphasized the importance of training of attachment in improvement of preschool children & apos; s attachment and well-being. More studies are suggested to understand better efficacy of maternal behavior on preschool children & apos; s well-being.

Torrance tests of creative thinking have been widely used to measure the impact of different items such as creativity on different groups of children. In this study, we perform an empirical study to measure the effects of endurance, power-based and flexibility on a group of children's creativity, originality and flexibility. The study chooses a sample of 341 from 2978 preschool children and distributes a questionnaire among them where 153 were female and 188 of them were male. Cronbach alpha for creativity, originality and fluency were calculated as 0.814, 0.822 and 0.788, respectively. The results of our study indicate that there are some positive and meaningful relationship among three components of creativity, originality and fluency before and after accomplishing test. The impact of test was measured for three types of sport activities including endurance, power-based and flexibility tests. After applying 32 sessions of sporting games, flexibility games represent a mean value of 32.40, which is higher than the other two tests and it maintains meaningful value compared with two other sporting tests of endurance and power base tests.
