本研究旨在探討智慧型手機使用者的社交焦慮、自覺手機人際互動與手機依賴之現況與相關性、預測力及自覺手機人際互動的中介效果，主要瞭解智慧型手機使用者不同背景變項在手機使用行為、社交焦慮、自覺手機人際互動與手機依賴的差別；以及社交焦慮、自覺手機人際互動與手機依賴的相關性、預測力及自覺手機人際互動的中介效果。採取隨機抽樣方式進行問卷調查法，研究工具包含：「智慧型手機使用行為問卷」、「社交焦慮量表」、「自覺手機人際互動量表」、「手機依賴量表」等四個部分。
本研究編製「自覺手機人際互動量表」與「手機依賴量表」並以639位智慧型手機使用者為樣本，進行信、效度考驗。研究結果發現：社交焦慮程度與年齡成反比，年紀愈輕社交焦慮程度愈高；手機依賴與年齡成反比，年紀愈輕手機依賴程度愈高。社交焦慮程度較高者，自覺手機人際互動愈佳，對手機依賴程度愈高。社交焦慮和自覺手機人際互動及手機依賴有顯著相關性，社交焦慮與自覺手機人際互動能預測手機依賴，自覺手機人際互動在社交焦慮與手機依賴間存在部分中介效果。
年輕族群對真實人際互動容易感到焦慮，對手機依賴程度也較高，因此年輕族群應多重視真實世界的人際互動關係，減少對虛擬線上人際的依賴。
The aim of this study is to investigate relationships among smartphone users’ usage behaviors, social anxiety, perceived interpersonal interaction on mobile phone, and mobile phone dependency. Furthermore, to examine the prediction and meditational effect of social anxiety and mobile phone dependence on perceived interpersonal interaction. Study instruments include “Smartphone usage behaviors questionnaire”, “Self-perceived interpersonal interaction on mobile phone scale”, “Social anxiety scale”, and “Mobile phone dependence scale”. This study applied random sampling method to survey smartphone owners aged above 18. A total of 639 smartphone users were surveyed and analyzed through exploratory factor analysis and reliability tests.
The study results reveal that social anxiety and mobile phone dependence are negatively correlated with age. Further, there are positive correlations among smartphone users’ social anxiety, self-perceived interpersonal interactions, and mobile phone dependence. In addition, social anxiety and self-perceived interpersonal interaction can predict mobile phone dependency with meditational effects.
Young mobile phone users perceive higher anxiety on interpersonal interactions and higher smartphone dependence compared to adult and older users. Research results suggest young generation engage in more real world interpersonal interactions to reduce dependence on virtual online interpersonal relationships.
