本研究探討以大學生族群為對象，主要研究兩個路徑關係，直接路徑為智慧型手機使用正向預期預測智慧型手機成癮之關係，間接路徑為智慧型手機使用正向預期透過智慧型手機使用負向預期預測智慧型手機成癮及憂鬱調節此路徑關係中的角色。資料收集共一千二百一十二名新生之智慧型手機成癮相關量表，包含柯氏智慧型手機成癮量表、智慧型手機使用正向預期問卷、智慧型手機使用負向預期問卷和憂鬱問卷。調節式中介結果顯示，在大學生智慧型手機成癮發展的歷程中，憂鬱會調節智慧型手機使用正向預期到智慧型手機使用負向預期之間的關係，以及憂鬱會調節智慧型手機使用負向預期與智慧型手機成癮之關係。亦即，當憂鬱愈高時，智慧型手機使用正向預期越能夠預測智慧型手機使用負向預期，而智慧型手機成癮度易增高；則當憂鬱愈低時，智慧型手機使用正向預期較不能夠預測智慧型手機使用負向預期，而智慧型手機成癮不易增高。
The present study examined the role of the Smartphone use negative outcome expectancy and depression in the pathways of the relationship between Smartphone use positive outcome expectancy and smartphone addiction among college adolescents. Data were gathered from one thousand, two hundred and twelve freshmen by the online survey. The moderated mediation analyses showed that depression moderated the association of positive outcome expectancy with negative outcome expectancy as well as the relationship linking negative outcome expectancy to smartphone addiction, such that the mediated effect strengthened under high depression than under low depression. The present study illuminates how the interaction between Smartphone use outcome expectancy and depression may make an impact on the development of Smartphone addiction among college students.
