Taking boundary theory as a starting point, this quantitative diary study examines the potential impact of private smartphone use at work—i.e., boundary-crossing behavior—on employee well-being. We hypothesized that private smartphone use would be positively associated with the subjective experience of being interrupted, especially when smartphone use was appraised negatively (vs. positively). Additionally, we predicted that these interruptions by private smartphone use would be positively related to end-of-day exhaustion, and that this relationship would be stronger for employees who value work over family (high vs. low work centrality). The hypotheses were tested using a sample of 67 employees from various occupations who completed a short daily questionnaire for four successive workdays (N = 237 data points). The results of multilevel analyses generally supported the hypotheses. Theoretical and practical implications of our findings are discussed.

工作期间使用私人智能手机：关于整合工作和家庭领域的未开发成本的日记研究

textabstract 在通讯技术（即智能手机）的推动下，许多员工采取工作家庭一体化策略，同时应对工作和家庭需求。以边界理论为起点，这项定量日记研究检验了工作中使用私人智能手机（即跨界行为）对员工幸福感的潜在影响。我们假设私人智能手机的使用与被打断的主观体验呈正相关，尤其是当智能手机的使用受到负面评价时（相对于正面评价）。此外，我们预测这些因使用私人智能手机而造成的干扰将与一天结束时的疲惫呈正相关，并且对于重视工作重于家庭的员工（高与低工作中心性），这种关系会更强。假设使用来自不同职业的 67 名员工组成的样本进行了测试，这些员工在连续四个工作日内完成了简短的日常问卷调查（N = 237 个数据点）。多层次分析的结果普遍支持这些假设。讨论了我们发现的理论和实践意义。
