This study examined the test-retest reliability, inter-rater reliability, convergent validity and discriminant validity of the Fine Motor Scale of the Peabody Developmental Motor Scales-second edition (PDMS-FM-2). Participants included two groups of 18 children between the ages of 4 and 5 years with and without mild fine motor problems. The PDMS-FM-2 was administered twice to 12 children and rated by two occupational therapists. The PDMS-FM-2 results were compared with scores on the Movement Assessment Battery for Children (M-ABC). In addition, the scores of the children with and without fine motor problems were compared. For the test-retest reliability and the inter-rater reliability, correlation coefficients varied from r = 0.84 to r = 0.99. These results suggest that PDMS-FM-2 has excellent test-retest and inter-rater reliability. Convergent validity with the fine motor section of the M-ABC and discriminant validity have been confirmed. Only 39% of the children in the group with problems in fine motor activities had fine motor problems according to the PDMS-FM-2. This finding seems to indicate that the PDMS-FM-2 may not be sensitive enough for this population.
