Despite the international body of research, the theoretical conceptualization of the construct math anxiety is still debated, showing strong discrepancies regarding its factor structure. Therefore, the aim of this paper is to develop and validate a new instrument, called Scale for Assessing Math Anxiety in Secondary education (SAMAS), by testing several models through confirmatory factor analysis. Data were collected from 563 secondary students, with an average age of 13.96 (SD=1.09) years. Several models for the construct were tested through confirmatory factor analysis. The results largely confirmed that the hierarquical structure showed the best fit to the data (χ2(166, N=563)=361.22; RMSEA=.046; SRMR=.045; NNFI=.94; CFI=.95), resulting in the psychometrically sound 20-item SAMAS, wherein math anxiety comprises three underlying factors.
