目的·探索序列模式挖掘在心理卫生领域的应用，同时分析课程对心理健康服务人员危机干预技能提高的作用。方法·利用在线学习平台记录的学习日志数据进行序列模式挖掘，并结合活动图对不同学习绩效的学习者的学习路径进行可视化分析。结果·在各集案例学习中，不同学习绩效的学习者的高频序列数具有显著差异，均为高绩效组>中绩效组>低绩效组。在危机干预咨询学习过程中，高绩效组学习者具备最为多样的学习路径；中绩效组由于缺乏对几个特定危机干预六步法步骤的掌握，学习路径完整性较差；而低绩效组则不具备完整的学习路径。结论·多样化的危机干预策略有助于咨询进程的顺利推进，针对不同学习绩效的学习者，应根据其学习特点制定相应的技能发展策略。

Objective · To explore the application of sequential pattern mining to the field of mental health, and analyze the role of the courses in improving the crisis intervention skills of mental health service personnel. Methods · The learning log data recordedthe online learning platform was used for sequential pattern mining, and the activity map was used to visually analyze the learning paths of learners with different learning performances. Results · In each case study, the number of high-frequency sequences of learners with different learning performance had significant differences, which were high-performance group > medium-performance group > low-performance group. In the crisis intervention consultation learning process, the high-performance group learners had the most diverse learning paths; the medium-performance group lacked the mastery of the several specific steps of the six-step model of crisis intervention, and the learning path integrity was poor; the low-performance group did not have a complete learning path. Conclusion · Diversified crisis intervention strategies are conducive to the smooth progress of the consultation process. Learners with different learning performance should develop corresponding skills development strategies according to their learning characteristics.
