This study investigated the antecedents and the performance impact of two types of Smartphone functions (communication vs. computing functions) in organizational environment and the moderating impact of Smartphone users' organizational roles. More specifically, identifying two distinct types of Smartphone functions such as communication functions and computing functions (including informational, social network, and resource management functions), we investigated the impact of three antecedents (Smartphone dependency, task mobility, and perceived critical mass) on the use of the two Smartphone functions and how organizational workers' perceived performance gains differ by using these two different Smartphone functions for their workplace activities. We tested our hypotheses with survey data collected from 176 organizational workers. Our findings suggest that Smartphone dependency, task mobility and perceived critical mass of Smartphone use are significantly associated with the use of the two different functions, and that the use of computing functions is more strongly associated with perceived performance gain than the use of communication functions. We also found that managerial roles played by individual workers differently moderate the impact of Smartphone use on perceived performance gain. The present findings enable researchers and practitioners to better understand the impact of Smartphone use in workplaces.

본 연구는 청소년의 일상 스트레스와 스마트폰 이용 및 중독이 학업에 어떤 영향을 미치는지 파악하고, 스마트폰 이용에 대한 부모의 중재 효과를 분석하는 데 그 목적이 있다. 이를 위해 청소년(13~18세)을 대상으로 스마트폰 이용 전반에 관한 온라인 설문조사를 실시하였다. 분석 결과, 오락적 목적의 스마트폰 이용 및 스마트폰 중독 경향성이 청소년의 학업 장애 요인으로 나타났다. 또한 가족 간 갈등, 학업, 미래에 대한 압박감 차원의 스트레스가 스마트폰 이용에 따른 학업장애를 이끈다는 것 역시 확인할 수 있었다. 부모의 중재는 그 유형에 따라 스마트폰 이용 및 중독, 학업장애 요인에 대해 서로 다른 효과를 갖는 것으로 나타난다. 이용시간을 제한할수록 오락적 이용이 증가하고, 이용하는 앱을 제한할수록 정보적 이용이 감소하는 것으로 나타났다. 참여적 형태의 부모 중재는 커뮤니케이션을 위한 스마트폰 이용이 증가하며, 앱을 추천하는 방식의 부모 중재는 스마트폰 중독지수를 감소시키는 것을 알 수 있었다.

스마트폰에 대한 관심과 사용이 집중되면서 사용 범위 또한 점차 넓어져 공적 업무처리 이외에 사적 업무처리와 동시에 사회 연결망 확장에도 사용되고 있다. 최근 스마트폰의 다양한 기능들은 사용자로 하여금 스마트폰을 사용하면서 동시에 다른 활동도 함께하는 멀티태스킹 행동을 유발하며, 스마트폰 사용에 집중하고 몰입하여 결국 사용자가 스마트폰을 사용하지 않으면 불안해지는 중독현상까지 나타내고 있다. 이에 본 연구에서는 개인적 특성이 스마트폰의 멀티태스킹 행동에 어떠한 영향을 미치는지 파악하고자 하였으며, 멀티태스킹 행동, 만족, 몰입 및 중독 간에 미치는 영향 관계에 대해 알아보고자 하였다. 선행 연구를 바탕으로 개인 특성 요인을 복합시간성, 혁신성, 자기효능감으로 설정하고 이러한 요인이 멀티태스킹 행동에 미치는 영향과 멀티태스킹 행동, 만족, 몰입 및 중독에 미치는 영향을 살펴보았다. 연구결과, 스마트폰 사용자의 복합시간성은 멀티태스킹 행동에 영향을 주는 것으로 나타났으나, 혁신성과 자기 효능감은 멀티태스킹 행동에 영향을 주지 않는 것으로 나타났다. 또한, 멀티태스킹 행동은 만족, 몰입 및 중독에 모두 긍정적인 영향을 미치는 것으로 조사되었으며, 만족은 중독에 영향을 주지 않지만, 몰입에 긍정적인 영향을 주는 것으로 나타났다. 마지막으로 몰입은 중독에 긍정적인 영향을 미치는 것으로 나타났다. 따라서 사용자의 멀티태스킹 행동은 중독에 직접적으로, 또는 몰입을 통하여 간접적으로 영향을 미치고 있는 것으로 나타났다.
