J. Olivares et al., The social phobia scale and the social interaction anxiety scale: Factor structure and reliability in a Spanish-speaking population, J PSYCHOED, 19(1), 2001, pp. 69-80
The factor structure of the Social Inter action Anxiety Scale (SIAS) and th
e Social Phobia Scale (SPS) was evaluated in a Spanish university student s
ample. The objective of this study was to examine whether these scales are
reliable measures in other languages and/or cultures. High levels of intern
al consistency were found. The results from the factor analyses replicated
the structure proposed by the original authors and revealed that both scale
s are unidimensional and appear to measure different aspects of the social
anxiety construct. Further, as in previous studies, gender differences were
found on the SPS but not on the SIAS. Results support the psychometric pro
perties of both the SIAS and the SPS in the assessment of Spanish-speaking
samples.
