Abstract

The purpose of this paper is to determine the factorial validity and group invariance of the Portuguese short-version of the Social Physique Anxiety scale (SPAS). A nationally representative sample of 3330 8th and 10th grade students (mean age = 15.07 ± 1.34 years) completed Motl and Conroy’s (2000) 7-item SPAS version. Principal component analysis followed by factor analysis resulted in a 6-item instrument with good internal reliability. Evidence of configural invariance and metric invariance across a variety of samples (as a function of gender, physical activity, diet behavior, perception of body and body mass index) indicate that Social Physique Anxiety construct generalizes across a variety of groups. The current short version should be tested in cross-cultural research.
