The association of problematic smartphone use with family well-being mediated by family communication in Chinese adults: A population-based study.

Background And Aims: Few studies have investigated the effects of problematic smartphone use (PSU) in the family context. We studied the association of PSU as a predictor with family well-being and the potential mediating role of family communication in Hong Kong Chinese adults.

Methods: We analyzed data of 5,063 randomly selected adults [mean age () = 48.1 (18.2) years; 45.0% men] from a dual landline and mobile telephone survey in 2017. PSU was assessed by the Smartphone Addiction Scale-Short Version with higher scores indicating higher levels. Family well-being was assessed by three questions on perceived family health, harmony, and happiness (3Hs) with higher scores indicating greater well-being. Perceived sufficiency and quality of family communication were rated. Multivariable regression analyses examined (a) associations of PSU with family 3Hs and well-being and (b) mediating role of family communication, adjusting for sociodemographic variables.

Results: PSU was negatively associated with perceived family health (adjusted β = -0.008, 95% CI = -0.016, -0.0004), harmony (adjusted β = -0.009, 95% CI = -0.017, -0.002), happiness (adjusted β = -0.015, 95% CI = -0.022, -0.007), and well-being (adjusted β = -0.011, 95% CI = -0.018, -0.004). Perceived family communication sufficiency (adjusted β = -0.007, 95% CI = -0.010, -0.005) and quality (adjusted β = -0.009, 95% CI = -0.014, -0.005) mediated the association of PSU with family well-being, with 75% and 94% of total effects having mediated, respectively.

Discussion And Conclusions: PSU was negatively associated with family well-being, which was partially mediated by family communication. Such findings provide insights for health programs to prevent PSU and improve family well-being.
