Validation of the Mobile Application Rating Scale (MARS).

ABSTRACT:

Background

Mobile health apps (MHA) have the potential to improve health care. The commercial MHA market is rapidly growing, but the content and quality of available MHA are unknown. Instruments for the assessment of the quality and content of MHA are highly needed. The Mobile Application Rating Scale (MARS) is one of the most widely used tools to evaluate the quality of MHA. Only few validation studies investigated its metric quality. No study has evaluated the construct validity and concurrent validity.

Objective

This study evaluates the construct validity, concurrent validity, reliability, and objectivity, of the MARS.

Methods

Data was pooled from 15 international app quality reviews to evaluate the metric properties of the MARS. The MARS measures app quality acros
