Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Background:

Evaluating the quality of health apps is crucial due to their impact on health decisions and outcomes.
The Mobile App Rating Scale (MARS) is a comprehensive tool for app quality evaluation, available in several languages but not Arabic.
There is a need for a validated Arabic version of MARS to assess health apps in Arabic-speaking regions.

Purpose of the Study:

To translate and culturally adapt the Mobile App Rating Scale (MARS) into Arabic (MARS-Ar).
To validate the MARS-Ar tool using a sample of health apps focused on obesity management.
To ensure the reliability and validity of the Arabic version for assessing health app quality.

Main Methods:

A universalist cross-cultural adaptation process using mixed methods was employed.
The MARS tool underwent translation, back-translation, and expert review.
The MARS-Ar was piloted and validated by two researchers on 66 weight management apps, with interrater reliability assessed using intraclass correlation coefficients (ICCs).

Main Results:

The Arabic translation (MARS-Ar) demonstrated high alignment with the original English MARS.
Good interrater reliability was established for MARS-Ar (ICC=0.836) and MARS English (ICC=0.838).
MARS-Ar subscales showed high correlations with their English counterparts, with usability exhibiting the lowest correlation (r=0.685).

Conclusions:

MARS-Ar is a valid and reliable instrument for assessing the quality of health and fitness apps among trained Arabic-speaking users.
Researchers and public health professionals in the Arab world can utilize MARS-Ar for consistent evaluation of weight management apps.
Further research is recommended to test MARS-Ar with apps addressing diverse health conditions.
