Amsterdam complex pelvic pain symptom scale with subscales: Based on a Norwegian translation, psychometric assessment and modification of the Amsterdam hyperactive pelvic floor scale.

A modified Norwegian version ACPPS-30 was presented, in addition to a shorter version with only 16 of the translated items distributed among five factors similar to the original Dutch version (ACPPS-16). Both versions proved to be valid, stable and reliable tools to investigate complex pelvic pain symptoms possibly due to an abnormally high-toned pelvic floor muscle.
