<div>Overall, the majority of generic preference-based quality of life measures (e.g., Health Utility Index, EuroQoL, SF-36 Health Survey) had good construct validity (i.e. measuring the constructs the test sets out to measure).</div>
<div>
<ul>
<li>Moderate to strong correlations were found between the generic measures and Parkinson's-specific measures (e.g., Parkinson's Disease Questionnaire-39) on the physical attributes of Parkinson's disease.</li>
<li>These generic measures did not strongly correlate on the non-physical attributes of Parkinson's disease (e.g., cognition, communication) and lacked responsiveness to change over time for this population. </li>
</ul>
