The Dynamic Adjustment of Physical Self in Adults
Author(s): Grégory Ninot, Marina Fortes, Didier Delignières, Christophe Maïano
Abstract: This study examined the dynamics of global self-esteem and physical self- perception in eight sedentary adults. Each participant completed the shortened version of the Physical Self Inventory, which measured global self-esteem (GSE), physical self- worth, and four physical sub-domains, everyday between 7:00 and 9:00 a.m. and 7:00 and 9:00 p.m. over the year 2001. Two weeks later, they completed the same inventory, in an isolated room every 5 minutes for 4 hours and 15 minutes. The auto-regressive integrated moving average (ARIMA) procedures showed that the dynamics of GSE and physical self dimensions were non-stationary over two consecutive semesters or one year. The ARIMA indicated that all the perceived dimensions functioned as a moving average model (0.1,1) without significant constant. Inversely, the time series obtained in an isolated room showed 88% random oscillations around a local value, which indicated a (0,0,0) model.
