Although this instrument has been validated in different cultural contexts, there are no studies to date that analyze its psychometric properties in a Mexican sample. Method: 307 adults completed the SPQ, seven participants were removed for being at high risk of psychosis. The fi nal sample was made up of 300 participants (M = 34.58, SD = 13.77), of whom 62.8% were female. Raine’s three-factor model and Stefanis et al.’s four-factor model were tested. Results: The results indicated that both factor structures had a good fi t to the data. However, the best evidence was for the three-factor solution. Confi gural, metric, and scalar invariance according to gender and age for the three-factor model was displayed. Further analyses showed women scored slightly higher in excessive social anxiety but this result was not statistically signifi cant. Younger participants had higher scores on ideas of reference, excessive social anxiety, no close friends, and odd speech than the older group. Conclusions: These fi ndings provide support for the use of the SPQ in the Mexican population.
