The present study aims to analyze the dimensionality of physical self-concept through confirmatory factor analysis of the AFI questionnaire (Esnaola, 2005; Esnaola & Goñi, 2006) and to compare two models: a) a quadri-dimensional model in which physical self-concept is made up of the sub-domains ability, condition, attractiveness and strength, and, b) a three-factor model in which the items corresponding to ability and condition are grouped together as one factor. The sample consists of 1,259 participants ranging in age from 12 to 84 years old (700 women and 556 men) who were divided into four groups as a function of age: 627 adolescents (12-18 years old), 272 young people (19-30 years old), 248 middle-aged adults (31-49 years old) and 112 people over 55, all living in the Basque Autonomous Region of Spain. The results indicate that the quadri-dimensional model of physical self-concept fits the data better than the three-dimensional model (which showed poor goodness of fit) for the study's total sample, as well as within the male and female sub-samples. Furthermore, the four-factor model was found to be stable throughout adolescence, youth and middle-age, but not for the group of adults over 55.
