Mobile Phone Dependence As A Mental Health Concern: A Comprehensive Review

Abstract

The dependence of mobile phones became an important behavioral and mental health problem in the modern society. Smartphones have revolutionized the way people communicate and gain access to information, but overuse and misuse are now linked to psychological distress. This extensive review combines the latest scientific knowledge on the dependence of mobile phones and mental health consequences.

The study was performed to review narratively the literature published from 2009 to 2022 and accepted for publication. The following databases were systematically searched with the keywords: PubMed, Google Scholar, Web of Science, and Scopus: "mobile phone dependence," "smartphone addiction," "problematic smartphone use," "depression AND mobile phone," and "anxiety AND smartphone dependence. Research focused on mental health outcomes such as depression, anxiety, stress, and psychological well-being of excessive smartphone users was considered. There are significant positive correlations shown between high mobile phone dependence and high levels of depression, anxiety and stress. The connections between these and psychopathology are underpinned by several psychological processes, including dopamine reward sensitization, dysregulation of emotional responses, and fear of missing out (FOMO). Circadian rhythm function is impaired by both blue light exposure and night time engagement, sleep disruption is a critical mediating pathway. There is a decrease in concentration, causing a corresponding decrease in academic and occupational performance, and an increase in procrastination. Social relationships suffer as the quality of face-to-face interaction decreases and so does the term "phubbing".

Adolescents and young adults are especially vulnerable because they are still developing, such as in the prefrontal cortex, and they have a heightened sensitivity to rewards. Smartphone dependence and mental health are a two-way street; mental health issues make people feel the need to use their smartphones more, and this dependency can exacerbate their psychological problems. The mobile phone dependence phenomenon is a public health issue that needs to be addressed from a holistic perspective because it demands a joint effort from mental health workers, education institutions, families, policy makers, and technology providers to foster more balanced and healthy use of technology and safeguard mental health in the digital era.
