The objective was to determine the psychometric properties of the Dimensions of Psychosis Instrument (DIPI) in Mexican patients with schizophrenia spectrum disorders. One-hundred patients were recruited. Convergent and divergent validity were determined with the positive and negative scores of the Positive and Negative Syndrome Scale; a forced five-factor exploratory principal-components analysis with varimax rotation was developed. Total DIPI score shows an adequate convergent validity. The rotated principal component matrix accounted for 82.1% of the variance. Our study gives further support of the adequacy of the DIPI for the assessment of the five most common subjective experiences related to psychosis.
