Flourishing through Social Development Activities and Social Support: A Holistic Strategy for Problematic Smartphone Use.

While some research has indicated the relationship between participation in social development activities (PSDA) and perceived social support (PSS) with problematic smartphone use (PSU), there has been a lack of studies examining these relationships through the lens of the flourishing theory, particularly among adolescents. To address this gap in the literature, this study conducted between April and May 2022 included 4965 high school students from 20 different cities in Türkiye. Researchers utilized questionnaires assessing participants' demographic information, levels of participation in social development activities, The Smartphone Application-Based Addiction Scale, The Short Version of the Scales of General Well-Being (GWB), and The Multidimensional Scale of Perceived Social Support as instruments. Structural Equation Modeling was employed for analyzing the relationships between variables using IBM SPSS v26 and AMOS v24 software packages. Hierarchical regression analysis was used to understand how GWB and PSS were associated with the relationships between PSDA and PSU. Findings indicated a predominantly negative relationship between PSDA and PSU, with GWB mediating this relationship negatively across all PSDA and PSS playing a contributory role in many indirect relationships between PSDA and PSU, if not directly. The importance of the approach in interventions aimed at addressing PSU was emphasized.
