Motivational interviewing is a technique for developing and maintaining motivation. This pilot study examined the feasibility and acceptability of motivational interviewing in online weight-loss treatment groups. Twenty women participated in the 8-week minimal contact intervention, received weekly e-mailed lessons, and were randomized to two online groups using motivational interviewing, either with or without a discussion of values. Acceptability of format and content was measured following the second online group. Self-reported weight and motivation were measured at baseline and 8 weeks. Qualitative analysis of group transcripts examined self-motivational statements uttered by participants during online groups. Eighty-four percent of participants reported willingness to participate again and were comfortable with the discussion topics. The average number of self-motivational statements uttered by participants did not differ by group (P=0.85) and was correlated with an increase in autonomous motivation during the 8 weeks (r=0.58, P=0.05). Higher autonomous motivation at follow-up was associated with greater weight loss (r=0.51, P<0.05). This study suggests that motivational interviewing techniques are acceptable and may be useful for targeting and maintaining motivation in online weight-loss groups.
动机性访谈是一种培养和维持动机的技术。这项试点研究考察了动机性访谈在在线减肥治疗组中的可行性和可接受性。20名女性参与了为期8周的最低限度接触干预，每周收到电子邮件课程，并被随机分配到两个使用动机性访谈的在线小组，一个讨论价值观，另一个不讨论价值观。在第二次在线小组讨论后测量了形式和内容的可接受性。在基线和8周时测量了自我报告的体重和动机。对小组记录的定性分析考察了参与者在在线小组讨论期间说出的自我激励陈述。84%的参与者表示愿意再次参与，并对讨论话题感到满意。参与者说出的自我激励陈述的平均数量在两组之间没有差异（P = 0.85），并且与8周内自主动机的增加相关（r = 0.58，P = 0.05）。随访时较高的自主动机与更大的体重减轻相关（r = 0.51，P < 0.05）。这项研究表明，动机性访谈技术是可接受的，并且可能有助于在在线减肥小组中确定和维持动机。
