<p>The HJHS has been tested for reliability and validity in its integral, complete version. If any items are omitted or modified, we cannot ensure the reliability and validity of the modified score’s results.</p>
<p>When <strong>non-evaluable</strong> items are introduced and calculated into the HJHS score, that item and the total HJHS score will be “modified” when compared to the original HJHS reliability and validity testing. As such it is recommended that any non-evaluable scores be clearly identified as such and not left incomplete.</p>
