Philadelphia Mindfulness Scale (PMS): An Examination into the Cultural Validity and Reliability of the Turkish version of the PMS

The purpose of this study was aimed to psychometric validation of the Philadelphia Mindfulness Scale, which bidimensionally assessed mindfulness, into Turkish culture. This psychometric validation study was only conducted on nonclinical sample. The sample consisted of 638 participants (442 females, 196 males) within the age range of 18 to 51. To determine the construct validity of PMS confirmatory factor analyses were employed. The results indicated that a two-factor solution corresponding to the two constituent components of the construct. Reliability analyses were conducted for each subscale. Internal consistency was good for the awareness subscale (α= .80) and respectable for the acceptance subscale (α= .78). For the Awareness subscale, corrected item-subscale total correlations ranged from .32 to .60, item discrimination coefficient ranged from 29.89 to 69.90 and test-retest correlation was .74. For the acceptance subscale, corrected item-subscale total correlations ranged from .39 to .63, item discrimination coefficient ranged from 36.62 to 58.39 and test-retest correlation was .80. There were significant positive relationships with respect to the correlation analysis employed for the convergent validity of FMS. The results indicated that FMS was a valid and reliable instrument for measuring mindfulness in Turkish culture
