Infant Movement Motivation Questionnaire: development of a measure evaluating infant characteristics relating to motor development in the first year of life.

This paper highlights the development and testing of the Infant Movement Motivation Questionnaire (IMMQ), an instrument designed to evaluate qualities of infant characteristics that relate specifically to early motor development. The measurement development process included three phases: item generation, pilot testing and evaluation of acceptability and feasibility for parents and exploratory factor analysis. The resultant 27-item questionnaire is designed for completion by parents and contains four factors including Activity, Exploration, Motivation and Adaptability. Overall, the internal consistency of the IMMQ is 0.89 (Cronbach's alpha), with test-retest reliability measured at 0.92 (ICC, with 95% CI 0.83-0.96). Further work could be done to strengthen the individual factors; however it is adequate for use in its full form. The IMMQ can be used for clinical or research purposes, as well as an educational tool for parents.
