SS, perceived social support; SA, smartphone addiction. Standardized coefficients. Standard errors and 95% percentile confidence intervals are based on 5,000 bootstrap resamples; an interval that excludes zero indicates a significant effect. All equations controlled for age, gender, only-child status, BMI category, parents’ education level, family size and self-rated physical health.
