ABSTRACT This study investigated second screen user behavior in a social television-viewing environment. Two online consumer panels of 1,052 second screeners were sampled to complete the three-stage research strategy. Through conceptualization and operationalization of the second screening construct, this study identified five underlying dimensions, including utility, control, interaction, influence, and attention. These five dimensions demonstrate different functionalities delivered by digital devices, such as laptop computers, tablets, and smartphones, to interact with television content. The theoretical and practical implications of second screening were also discussed.

二次放映：测量社交电视观看环境中的二次放映用户行为

摘要 本研究调查了社交电视观看环境中的第二屏幕用户行为。对 1,052 名第二筛选者的两个在线消费者小组进行了抽样，以完成三阶段研究策略。通过第二个筛选结构的概念化和操作化，本研究确定了五个潜在维度，包括效用、控制、交互、影响和注意力。这五个维度展示了数字设备（例如笔记本电脑、平板电脑和智能手机）提供的与电视内容交互的不同功能。还讨论了第二次筛选的理论和实践意义。
