Psychometric properties of the Spanish version of the Philadelphia Mindfulness Scale

© 2014 SEP y SEPB. Conclusions: The Spanish version of the PHLMS is a psychometrically sound measure for assessing two core components of mindfulness (i.e. awareness and acceptance) in clinical and research settings.Material and methods: The Spanish version of the PHLMS was administered to a sample of 395 volunteers (256 of them with a psychiatric condition, and 130 from a student sample).The Philadelphia Mindfulness Scale (PHLMS) is a brief questionnaire for assessing 2 key components of mindfulness: present moment awareness, and acceptance. This study was aimed at evaluating the psychometric properties of the Spanish version of PHLMS in a sample of participants with and without psychiatric conditions.Results: Exploratory factor analysis found a two factor solution, which was also observed in the original version of the scale, with an explained variance of 44.02%. The scale showed good reliability (Cronbach α between 0.81 and 0.86), and an adequate convergent validity with other questionnaires of mindfulness and acceptance. The results also showed a similar discriminant validity to that in the original instrument validation between PHLMS and the clinical symptomatology reported.
