This paper examined relationships between qualitative (developmental sequences) and quantitative (time) performance in rising from a supine position in early childhood. One hundred twenty two children ranging in age from 3 to 5 years were videotaped for five trials of rising from a supine position. Children’s performance on the supine-to-stand (STS) task was quite variable in terms of both qualitative movement patterns and time (mean = 2.37 s, SD = .60). Results: Component sequences were moderately to strongly correlated with each other (r = .387 to .791). Upper-extremity (r = –.383) and axial (r = –.416) component levels also were inversely correlated with STS time. Results indicated a strong coordinative link between the development of trunk control (i.e., axial movement) and upper-extremity movement levels (r = .791), and together they demonstrated the strongest impact on the ability to rise quickly. These data provide important information relating to a child’s motor development that may have clinical relevance for diagnosis. It provides also a greater understanding on how to improve performance on this task. Future research should examine qualitative and quantitative aspects of STS performance to understand its predictive utility as a lifespan assessment of motor competence and its potential importance as a measure to predict healthrelated variables and functional capability across the lifespan.

Perceived motor competence (PMC) is a psychological construct that may be influenced by various environmental factors. This study aimed to analyze differences in PMC of children from four diverse countries. The sample was comprised of 231 Brazilian, 129 Australian, 140 Portuguese, and 114 American children, aged 5–8 years. The PMC was assessed using the Pictorial Scale of Perceived Movement Skill Competence for Young Children. Differences in PMC among countries were verified using Kruskal-Wallis tests, separately by age and gender. For girls (from the age of six), differences were found in the leap, slide, hit, and catch, as well as the sum of object control skills and total score. For boys, differences were found among countries in the gallop, jump, slide, hit, catch, and roll, as well as the sum of locomotor and object control skills, and the total skill score. Overall, American children seem to perceive themselves more competent compared to children from other countries. Leisure and sport activities in each country may influence the construction of PMC.
