This study investigates the effects of information technology (IT) identity on the use of personal health devices (PHDs). We conducted an online survey of individuals who used a PHD to achieve a health-related goal. The results confirm that IT identity is a multidimensional construct with three reflective dimensions. The results exhibit that the identity verification process (IT characterizes through IT experience) fosters IT identity, which, in turn, encourages individuals to engage in beneficial post-adoption behaviors such as feature use and enhanced use. The findings also reveal that perceived health status moderates the relationship between IT identity and positive use behaviors.

这项研究调查了信息技术（IT）身份对个人健康设备（PHD）使用的影响。我们对使用PHD实现健康相关目标的个人进行了在线调查。结果证实，IT身份是具有三个反射维度的多维构造。结果表明，身份验证过程（IT通过IT经验来表征）促进了IT身份，进而鼓励个人从事有益的采用后行为，例如功能使用和增强使用。研究结果还表明，感知的健康状况可以缓解IT身份与积极使用行为之间的关系。
