TABLE 1.

Classification system for scale recommendation

Category	Criteria

“Recommended”	(1) Scale has been used in HD populations. (2) Use in HD by groups other than the original developers and data on its use were available.^a (3) The available clinimetric/psychometric data in HD support the goals of screening (eg, evaluation of sensitivity/specificity, score cut points, and reliability) or measurement of severity (eg, evaluation of reliability, construct validity, and score discrimination across levels of symptom severity), or measurement of a change in severity (eg, responsiveness or sensitivity to change).
“Suggested”	(1) Scale has been used in HD populations. (2) Only one other criterion (2) or (3) from the above recommended category applies.
“Listed”	(1) Scale has been applied to HD populations, but no further criteria met.

HD, Huntington’s disease.

For rating scales not originally developed for use in HD, criterion 2 was fulfilled if used in at least 1 group in HD that reported any kind of clinimetric/psychometric data in HD.
