Objective and Subjective iPhone Use in Relation to App usage, Risk of Addiction and Device Use Deprivation

The dataset contains information from 100 adult iPhone users who provided objective smartphone usage data recorded via the Apple iOS Screen Time feature over eight consecutive days, alongside self-report questionnaire data. Variables include demographic information (age and gender), perceived smartphone use volume, and objectively measured total and average daily smartphone use. The dataset further includes time spent in 12 predefined application usage categories as classified by Screen Time, as well as aggregated hedonic and utilitarian use indices derived from these categories. Self-report measures comprise the Smartphone Application-Based Addiction Scale (SABAS) and the Smartphone Deprivation Inventory, including both total scores and individual component scores. In addition, the dataset contains component-level indicators of smartphone addiction reflecting salience, mood modification, tolerance, withdrawal, conflict, and relapse. Together, these variables enable integrated analyses of objective smartphone behaviour, subjective use perceptions, application-level usage patterns, and psychological correlates related to addiction risk and deprivation.
