Smartphone Addiction and Sleep Quality: An Empirical Study in Psychology Among College Students

The present empirical study titled “Smartphone Addiction and Sleep Quality: An Empirical Study in Psychology Among College Students” investigates the relationship between smartphone addiction and sleep quality among undergraduate and postgraduate students aged 18–25. With a sample of fifty randomly selected participants, data were collected using both in-person and online structured interviews. The Smartphone Addiction Scale (SAS) and the Pittsburgh Sleep Quality Index (PSQI) were employed as standardized instruments to measure smartphone dependency and sleep quality, respectively. Findings reveal that the average daily screen time exceeded five hours, while pre-sleep screen exposure was notably high, averaging more than seventy minutes. Sleep metrics indicated that although the majority reported good sleep quality, significant variations existed in sleep latency, nocturnal awakenings, and overall restfulness. Pre-sleep digital behaviors such as social media browsing, YouTube viewing, and gaming strongly influenced sleep outcomes. Lifestyle factors like caffeine consumption, late-night meals, perceived stress, and physical activity further moderated the relationship between smartphone use and sleep quality. The study highlights the complex interplay between technology use, behavioral habits, and psychological well-being, pointing to the need for interventions promoting healthy digital hygiene among college students
