Parental technoference, refers to the interruptions and interference caused by the technological devices in the parent-child communication, is one of the factors that leads to smartphone addiction among adolescents. The present research will examine how parental technoference is associated with adolescent smartphone addiction with moderating effects of peer attachment. Based on the social learning theory and Compensatory Internet Use Theory, the study hypothesised (1) there is a positive relationship between parental technoference and smartphone addiction, (2) parental technoference and peer attachment have a moderating relationship and (3) there are important differences between early (ages 12-13) and late adolescents (ages 18-19) in parental technoference, peer attachment and smartphone addiction. There were 140 adolescents who took part in the study. The interaction effects were analyzed through moderation analysis through Smart PLS. Findings revealed that technoference on the part of parents had a positive relationship with addiction to smartphones. This correlation was moderated by peer attachment, whereby the stronger the peer attachment, the weaker the relationship between parental technoference and smartphone addiction. Moreover, the adolescents in later stages of the adolescence phase showed higher smartphone addiction and peer attachment than those in early stages of the adolescence phases. These findings highlights the importance of technology to reduce parental technoference and strengthen peer attachment to counterbalance the effect of technology-related disturbances on adolescents' well-being.
