To investigate the potential for an email-based, mindful eating exercise to improve unwanted snacking habits.
Australian participants (N = 78, 86% female) with unwanted snacking habits engaged in a mindful eating email-based intervention, over a practice period of two weeks. All measures were completed using an online survey. Habit strength was measured using the Self-Report Habit Index (SHRI). Mindful eating was measured using the Mindful Eating Questionnaire (MEQ) and self-compassion was measured using the Self-Compassion Scale (SCS). Participants were emailed a mindful eating exercise and asked to make action plans to practice it. Reminders to perform the task were sent via email after one week. After two weeks, the MEQ, SCS and SHRI were readministered.
Habit strength significantly increased over the two-week period and self-compassion significantly decreased. The amount of practice reported was not associated with these changes, but self-reported effort expended during practice sessions was partially associated.
The intervention resulted in increased habit strength; potential mechanisms underlying these changes are discussed. Decreased self-compassion may be linked to both the electronic delivery of the intervention and the nature of the mindful eating task.
探讨基于电子邮件的正念饮食练习改善不良零食习惯的潜力。
有不良零食习惯的澳大利亚参与者（N = 78，86%为女性）在两周的练习期内参与了基于电子邮件的正念饮食干预。所有测量均通过在线调查完成。使用自我报告习惯指数（SHRI）测量习惯强度。使用正念饮食问卷（MEQ）测量正念饮食，使用自我同情量表（SCS）测量自我同情。向参与者发送一封正念饮食练习邮件，并要求他们制定行动计划来进行练习。一周后通过电子邮件发送执行任务的提醒。两周后，再次进行MEQ、SCS和SHRI测量。
在两周内习惯强度显著增加，自我同情显著降低。报告的练习量与这些变化无关，但练习期间自我报告的努力程度与之部分相关。
干预导致习惯强度增加；讨论了这些变化背后的潜在机制。自我同情的降低可能与干预的电子交付方式以及正念饮食任务的性质有关。
