ABSTRACT

Schade MM, Montgomery-Downs HE. Utility encompasses both clinical translation and ecologic validity. J Clin Sleep Med. 2019;15(11):1709.


We thank Dr. Hunasikatti1 (and others2) for their comments on our recent publication.3 We agree that “optimum information is more important than convenience,”1 a value that motivates objective product evaluations such as these. As emphasized in our report, the non-contact bedside device that we evaluated showed both strengths (eg, comparability to actigraphy’s strengths) and limitations (eg, wake discrepancies from polysomnography that are congruent with actigraphy’s limitations). We are sure all will agree that addressing a primary goal of validity includes addressing ecological validity, and that accessibility will also be an important characteristic of next-generation sleep technology.

DISCLOSURE STATEMENT

Work for this study was completed at West Virginia University. All authors have reviewed and approved this manuscript. Funding for the research pertaining to this commentary was provided by a grant from ResMed, Inc. and included summer stipends for graduate and undergraduate research staff (Schade), two S+ by ResMed bedside devices, and funds for purchasing disposable polysomnography supplies. Dr. Montgomery-Downs received no compensation from ResMed, Inc. The authors report no financial or other conflicts of interest.
