Assessing musical ability quickly and objectively: development and validation of the Short-PROMS and the Mini-PROMS.

The study of musical ability has gained considerable traction across disciplines in recent years. In comparison, less effort has been invested in the development of sound measures of musical ability. To redress this gap, we conducted four studies to empirically validate two brief measures derived from the Profile of Music Perception Skills (PROMS)-an exceptionally inclusive battery of musical abilities that takes about 1 h to complete. In the Short-PROMS, test duration was reduced to less than half an hour by substantially reducing the number of trials per subtest. In the Mini-PROMS, the number of subtests was reduced to four, resulting in a battery that takes 15 min to complete. Both measures exhibited good internal consistency and retest reliability. Support for convergent, discriminant, and criterion validity was found across the studies. Additional strengths of the new instruments include their suitability for online administration and a feature called Modular PROMS, which offers researchers the possibility to request customized batteries that may include any combination of the subtests. The role of refining objective assessment instruments in research on music and the mind is discussed.
