To study psychometric properties of two scales devised in Spain with the purpose of assessing the structure of social attitudes in that country. Variables The study uses two scales: 1) Burgaleta's (1976) RD40 scale which purports to measure two supposedly orthogonal factors: radicalism (as opposed to conservatism) and dogmatism (as opposed to flexibility). This was tested on 764 subjects (335 male and 420 female) attending a social psychology seminar at Madrid's Complutense University. 2) SPS or Spanish Psychosocial Scale (Giorgi and Seisdedos, 1982) which attempts to operationalize attitudes towards politics, religion, sexual practices, foreigners, military institutions and a wide range of controversial social issues. This was tested on a sample of 1409 subjects made up of 764 university undergraduates plus a group of 645 non-students. The latter comprised 365 males and 280 females, the males being drawn from the Spanish Army. (Military service is compulsory in Spain, and conscripts come from various regions).
