The Head Control Scale: Responsiveness and Concurrent Validity With the Alberta Infant Motor Scale.

Purpose: The purpose of this study was to investigate the Head Control Scale's (HCS's) responsiveness and concurrent validity with the Alberta Infant Motor Scale (AIMS).

Methods: The HCS and the AIMS were administered to 50 infants and young children. Thirty children were reevaluated at hospital discharge or at 18 months of age.

Results: A statistically significant positive change was noted in mean score from the initial HCS assessment to the second assessment for total score and all position scores. Concurrent validity between HCS and AIMS total scores was excellent.

Conclusion: Responsiveness to changes in head control and concurrent validity with the AIMS were established, supporting HCS use in clinical practice.
