简介：本研究的目的是测试使用短信（短消息服务[SMS]）对年轻人戒烟进行持续个人支持的干预的可行性和可接受性。此外，研究了最优反馈强度，并探讨了干预的短期效果。方法：在格赖夫斯瓦尔德大学的一家自助餐厅，对575名游客进行了吸烟和短信使用情况的筛查。从这些人中，194名符合每日吸烟和每周使用短信的纳入标准的人被邀请参加基于短信的干预。其中，174人（90%）同意参与。参与者被随机分配到三个研究组之一：(a)没有干预的控制条件，(b)每周一次短信反馈的干预（1条短信），或(c)每周一次短信反馈的干预（3条短信）。在研究组(b)和(c)中，根据基线评估的数据和根据跨理论模型对变化阶段的每周短信评估，每周向参与者发送个性化的短信反馈。比较支持强度不同的两个干预组的程序使用和接受程度。在为期3个月的吸烟变量干预计划结束时，通过比较三个研究组对该计划的短期疗效进行了探索。结果：对每周短信评估的回复中位数在1SMS组为12.5，在3SMS组为13.0（无统计学意义）。干预组对该计划的接受程度并无差异。在后评估中，三个研究组在检查的吸烟变量上没有显著差异。讨论：高参与率和保留率表明基于短信的戒烟干预对年轻人有吸引力。支持强度不影响方案的接受度。需要更长的随访时间和更大的样本才能获得关于这种干预方法有效性的结论性结果。
Introduction: The objective of this study was to test the feasibility and acceptance of an intervention using text messaging (short message service [SMS]) for continuous individual support of smoking cessation in young adults. Additionally, the optimal feedback intensity was investigated, and short-term efficacy of the intervention was explored.Methods: In a cafeteria of the University of Greifswald, 575 visitors were screened for smoking status and usage of text messaging. From these, 194 persons who fulfilled the inclusion criteria of daily smoking and weekly usage of SMS were invited for participation in an SMS-based intervention. From these, 174 (90%) consented to participate. The participants were randomly allocated to one of three study groups: (a) control condition without intervention, (b) intervention with one weekly SMS feedback (1SMS), or (c) intervention with three weekly SMS feedbacks (3SMS). In study groups (b) and (c), individualized SMS feedbacks were sent to the participants weekly, based on data from the baseline assessment and a weekly SMS assessment of the stages of change according to the transtheoretical model. Program use and acceptance were compared between the two intervention groups differing in support intensity. An exploration of the short-term efficacy of the program was conducted by comparing the three study groups at the end of the 3-month intervention program on smoking variables.Results: The median number of replies to the weekly SMS assessments was 12.5 in the 1SMS group and 13.0 in the 3SMS group (not significant). The acceptance of the program did not differ between the intervention groups. At postassessment, no significant differences between the three study groups emerged on the examined smoking variables.Discussion: The high participation and retention rates suggest that SMS-based smoking cessation interventions are attractive for young adults. Support intensity did not affect the acceptance of the program. Longer follow-up periods and larger samples are required to obtain conclusive results about the efficacy of this intervention approach.
