Identifying Indicators of Smartphone Addiction Through User-App Interaction

Area of Science:

• Psychology
• Human-Computer Interaction
• Digital Wellbeing

Background:

• Traditional smartphone use monitoring relies on self-reporting or session timing, which can be inaccurate.
• Existing methods often focus on passive usage rather than active engagement with the interface.
• Problematic smartphone behavior requires a more direct and objective measurement approach.

Purpose of the Study:

• To introduce and validate a new method for monitoring smartphone activity through direct physical interface interactions.
• To investigate the correlation between specific interaction patterns and smartphone addiction.
• To identify which app categories and specific applications are most associated with problematic smartphone use.

Main Methods:

• Collected user interface interaction events (taps, scrolling, typing) from 64 participants over 8 weeks using the Tymer monitoring app.
• Focused on active smartphone engagement rather than passive metrics.
• Analyzed the relationship between interaction data and self-reported or assessed smartphone addiction levels.

Main Results:

• Smartphone addiction significantly correlated with high interaction frequency in Lifestyle apps, particularly among female users.
• Increased interaction with Social apps, including Snapchat, was strongly associated with smartphone addiction across all interaction types.
• Snapchat usage showed a notable link to smartphone addiction, suggesting its design may facilitate problematic engagement.

Conclusions:

• Monitoring physical interface interactions offers a direct and objective measure of problematic smartphone behavior.
• Lifestyle and Social apps, with Snapchat as a key example, are significantly associated with smartphone addiction.
• The design of apps like Snapchat may play a crucial role in fostering smartphone addiction, especially among younger demographics.
