After virtue, a study in moral theory

ADHD and the Nature of Self-Control

Although a substantial body of literature has explored the relationship between sleep and exercise, comprehensive reviews and definitive conclusions about the impact of exercise interventions on sleep are lacking. Electronic databases were searched for articles published between January 2013 and March 2017. Studies were included if they possessed either objective or subjective measures of sleep and an exercise intervention that followed the guidelines recommended by the American College of Sports Medicine. Thirty-four studies met these inclusion criteria. Twenty-nine studies concluded that exercise improved sleep quality or duration; however, four found no difference and one reported a negative impact of exercise on sleep. Study results varied most significantly due to participants’ age, health status, and the mode and intensity of exercise intervention. Mixed findings were reported for children, adolescents, and young adults. Interventions conducted with middle-aged and elderly adults reported more robust results. In these cases, exercise promoted increased sleep efficiency and duration regardless of the mode and intensity of activity, especially in populations suffering from disease. Our review suggests that sleep and exercise exert substantial positive effects on one another; however, to reach a true consensus, the mechanisms behind these observations must first be elucidated.

Objective: This research was designed to identify the validity and reliability of the Persian version of Denver Developmental Screening Test II (DDST-II) in Iranian children, in order to provide an appropriate developmental screening tool for Iranian child health workers. Methods: At first a precise translation of test was done by three specialists in English literature and then it was revised by three pediatricians familiar with developmental domains. Then, DDST-II was performed on 221 children ranging from 0 to 6 years, in four Child Health Clinics, in north, south, east and west regions of Tehran city. In order to determine the agreement coefficient, these children were also evaluated by Ages and Stages Questionnaires (ASQ) test. Because ASQ is designed to use for 4-60 month- old children, children who were out of this rang were evaluated by developmental pediatricians. Available sampling was used. Obtained data was analyzed by SPSS software. Findings: Developmental disorders were observed in 34% of children who were examined by DDST-II, and in 12% of children who were examined by ASQ test. The estimated consistency coefficient between DDST-II and ASQ was 0.21, which is weak, and between DDST-II and the physicians’ examination was 0.44. The content validity of DDST-II was verified by reviewing books and journals, and by specialists’ opinions. All of the questions in DDST-II had appropriate content validity, and there was no need to change them. Test-re test and Inter-rater methods were used in order to determine reliability of the test, by Cronbach’s α and Kauder-Richardson coefficients. Kauder-Richardson coefficient for different developmental domains was between 61% and 74%, which is good. Cronbach’s α coefficient and Kappa measure of agreement for test-retest were 92% and 87% and for Inter-rater 90% and 76%, respectively. Conclusion: Persian version of DDST-II has a good validity and reliability, and can be used as a screening tool for developmental screening of children in Tehran city.
