Psychological Traits, Addiction Symptoms, and Feature Usage as Predictors of Problematic Smartphone Use among University Students in China

This study investigates the effects of psychological traits (i.e., procrastination, leisure boredom, and impulsivity) and addiction symptoms on problematic smartphone use. Data were collected from a multistage random sample of 649 university students. The results showed that procrastination, impulsivity [including sensation seeking and (lack of) perseverance], symptoms of addiction (e.g., inability to control craving, withdrawal, and complaints), and frequent usage of smartphone features for instrumental, relational, expressive, and informational purposes were significant predictors of problematic smartphone use.
