The cultural component was accomplished through an external experts meeting and a longitudinal screening of concepts and construct. The pilot study was carried out in a sample of 50 Portuguese community-dwelling elders.

The DRUGS-PT (Portuguese version of DRUGS) mean score was 80.63, ±26.36 (range of 2.78 to 100; median of 91.67) in tests and 78.44, ±25.59 (range of 0 to 100; median of 87.5) in retests.
