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