Inclusion criteria

Inclusion criteria: In order to be eligible to participate in this study, a subject with PD must  meet all of the following criteria: • Men/women of age > 18 years with idiopathic Parkinson*s Disease, as diagnosed  by a movement disorders specialist.  • Written informed consent. In order to be eligible to participate in this study, a health care  provider/researcher must meet all of the following criteria: • Men/women of age > 18 years  • Experience with people with PD

Design outcomes

Primary

Measure	Time frame
The main parameters are psychometric attributes of a novel Parkinson*s Disease specific rating scale, that assesses the constructs gait (including freezing of gait), balance, posture and concerns about falling. Using CTT statistics, the following psychometric properties will be tested: data quality and acceptability, reliability (internal consistency and stability or test-retest reliability), precision and construct and structural validity. Using Rasch analysis, the following psychometric attributes are evaluated: internal construct validity, optimal scoringscheme, uni-dimensionality, item fit, item local independency, and item bias by subgroups of respondents. The test consistency will be assessed using test-retest reliability coefficients.	—
