# Validation of the immersion in digital life and quality of digital experience scales in German, French, Spanish, Polish and Czech

## TL;DR

This study validates two scales for measuring digital experiences in five languages, showing they reliably assess positive and negative aspects of technology use.

## Contribution

The QDES and IDLS scales are validated in German, French, Spanish, Polish, and Czech, expanding their cross-cultural applicability.

## Key findings

- Confirmatory Factor Analysis confirmed a three-factor model for the QDES across all languages.
- The IDLS was validated as having a single factor structure in all countries.
- Both scales showed good reliability and validity in all five languages.

## Abstract

The Quality of Digital Experience Scale (QDES) and the Immersion in Digital Life Scale (IDLS) were developed to measure positive and negative experiences of digital technology use and the extent to which different facets of life were digital. Critically, the QDES and ILDS were developed to be independent of digital device or platform, thus providing a more holistic account of digital technology use than previous measures. The objective of the current studies was to validate the QDES and IDLS in German, French, Czech, Polish and Spanish. Across the studies, data from a total of 4,447 participants were analyzed. Confirmatory Factor Analyses confirmed a three-factor model for the QDES consisting of Wellbeing, Social Connectedness and Time and Efficiency. The IDLS was also confirmed as having a single factor structure. Reliability and validity analysis indicated that the QDES and IDLS showed good reliability and validity in all countries. The present study confirms that the QDES and IDLS offer reliable measurements of individuals’ interactions with technology in the digital era. By extending the validation of these measures beyond English, to German, Polish, Czech, French and Spanish, we expand researchers and policy makers abilities to establish the positive and negative impacts of digital practices on individuals and societies.
