Proposing 6 dimensions within the construct of movement in the movement continuum theory

The Movement Continuum Theory (MCT) provides a potential basis for movement assessment and intervention, but "movement" lacks specificity. The purposes of this study were to propose and evaluate a subdivision of movement into multiple dimensions.

A convenience sample of 318 adults completed a 24-item self-report measure of movement ability.

A multimethod approach was used to identify, operationalize, and test a multidimensional model of movement. Data analysis included a comparison of the fit of unidimensional and multidimensional models using item response theory methods and inspection of response patterns.

A model specifying 6 dimensions--flexibility, strength, accuracy, speed, adaptability, and endurance--fit respondent data significantly better than the unidimensional model, even with high pair-wise correlations between dimensions. Response patterns showed large differences rather than uniform scores across dimensions for over half of the respondents.

Subdividing movement into the proposed dimensions fits the data and potentially strengthens the usefulness of the MCT as a theoretical foundation for managing movement effectively.
