  RESULTS
  Childhood physical abuse could directly predict less self-esteem and internet addiction disorder (r = -0.108, P < 0.01, r = 0.057, P < 0.01) and had significant indirect effects on internet addiction disorder which could be mediated through self-esteem (a = -0.703, standardized b = -0.104, z = 5.052, P < 0.001). Self-esteem had mediated 22.5% of the childhood physical abuse cases on their internet addiction disorders during the period of adolescence.
