The survey of personal beliefs: Comparison of south african, mexican and american samples

In order to investigate the cross-cultural reliability and independence of subscales of the Survey of Personal Beliefs (SPB) data from 751 undergraduate Psychology students (189 White South African students, 114 Black South African students, 262 Mexican students and 186 American students) were compared. Coefficient alphas for the subscales in all samples were low, ranging from .33 to .76. However, alphas for the total scale across all subgroups were high. A comparison of the rank ordering of alpha coefficients for subscales in the different samples partially supported the cross-cultural reliability of the SPB for White South African and Mexican students, and for Black South African and American students. The similarities across samples regarding intercorrelations and shared variance between subscales also provided some evidence for the possible cross-cultural independence of subscales of the SPB. Comparison of total and mean subscale scores showed no significant differences between males and females within samples. However, a significant effect for culture, with significant between-subject effects for all the subscales as well as for the total score, was found. This may be indicative of real differences in irrational belief styles between the groups or may be a result of the insufficient cross-cultural reliability of the SPB. © 2006 Springer Science+Business Media, Inc.
