Abstract

A sample of 442 native Spanish-speakers demonstrated good fit for the translated Psychological Insight Questionnaire, Challenging Experiences Questionnaire, and Mystical Experiences Questionnaire.

The study tested psychometric properties of acute psychedelic effects measures among Spanish-speaking individuals.
Confirmatory factor analysis indicated a good fit for the translated questionnaires based on their English counterparts.
Consistency in factor structure was observed across different drug subgroups (LSD and Psilocybin).
Significant positive associations were found between the Psychological Insight Questionnaire and the Mystical Experiences Questionnaire.
Persisting effects were strongly correlated with scores on both the Mystical Experiences Questionnaire and the Psychological Insight Questionnaire.

This study translated and tested the psychometric properties of acute psychedelic effects measures among Spanish-speaking people. The Psychological Insight Questionnaire (PIQ), Challenging Experiences Questionnaire (CEQ), and Mystical Experiences Questionnaire (MEQ) were translated before being incorporated into a web-based survey. We recruited native Spanish-speakers ( = 442; M = 30.8, SD = 10.9; Latino/Latina = 62%; Hispanic = 91.4%; male = 71.5%) to assess their previous experience with one of two psychedelics (LSD = 58.4%; Psilocybin = 41.6%) and their acute and enduring effects. Confirmatory factor analysis (confirming factor structure based on the English version) revealed a good fit for the MEQ, PIQ and the CEQ. Repeating our analysis in each drug subsample revealed consistency in factor structure for each assessment tool. Construct validity was supported by significant positive associations between the PIQ and MEQ, and between the PIQ and MEQ and changes in cognitive fusion and negative associations between changes in prosocial behaviors. As a signal of predictive validity, persisting effects (PEQ) were strongly related to scores on the MEQ and PIQ. Findings demonstrate that the Spanish versions of these measures can be reliably employed in studies of psychedelic use or administration in Spanish-speaking populations. N age
