Motives for digital social multitasking (DSMT) and problematic phone use among adolescents

Phone use during face-to-face interactions (i.e., digital social multitasking [DSMT]) is a growing activity among adolescents. DSMT appears to be a risk factor for problematic phone use, but little is known about why adolescents engage in DSMT and how different motives of DSMT would be associated with problematic phone use. Drawing on the framework of DSMT and the uses and gratifications theory, this study explored (1) the motives of adolescent DSMT and (2) the direct and indirect relationships between DSMT motives and problematic phone use via the level and perception of DSMT.The study involved survey data from 517 adolescents in the United States recruited through the Qualtrics panels (Mage = 14.83, SD = 1.93) in the fall of 2020. The sample's gender and racial/ethnic distributions were nationally representative.We developed a scale measuring adolescent DSMT motives, which showed that adolescents engaged in DSMT because of enjoyment and connection, boredom, information, and habitual use. The motive of habitual use was associated with problematic phone use both directly and indirectly via level of DSMT and perceived distraction caused by DSMT. The information motive was directly associated with problematic phone use, while the boredom motive was indirectly associated with problematic phone use via perceived distraction. Conversely, the motive of enjoyment and connection was related to lower problematic phone use both directly and indirectly via lower perceived distraction.The study identifies DSMT-related risk and protective factors for problematic phone use. The findings should help adults recognize adaptive versus maladaptive forms of DSMT among adolescents and develop proper guidance and intervention.
