Computer-based brief motivational interventions may be able to reach a high proportion of at-risk individuals and thus have potential for significant population impact. The present studies were conducted to determine the acceptability and preliminary efficacy of a computer-based brief motivational intervention (the motivation enhancement system, or MES). In Study 1, quantitative and qualitative feedback from 30 postpartum women and 17 women in treatment for drug use were used to modify the software. In Study 2, 50 urban postpartum women who reported drug use in the month before pregnancy completed the intervention and provided repeated within-session ratings of state motivation. In Study 3, 30 women were randomly assigned to intervention or control conditions with 1-month follow-up. Overall, women rated the MES as highly acceptable and easy to use and reported significant increases in state motivation at postintervention and at 1-month follow-up (d = .49). These preliminary results are encouraging and suggest that further work in this area is warranted.
基于计算机的简短动机干预可能能够覆盖很大比例的高危个体，因此具有对大量人群产生重大影响的潜力。本研究旨在确定一种基于计算机的简短动机干预（动机增强系统，或MES）的可接受性和初步疗效。在研究1中，来自30名产后妇女和17名接受药物使用治疗的妇女的定量和定性反馈被用于修改软件。在研究2中，50名在怀孕前一个月报告有药物使用情况的城市产后妇女完成了干预，并在疗程中多次提供了状态动机评分。在研究3中，30名妇女被随机分配到干预组或对照组，并进行了1个月的随访。总体而言，女性对MES的评价很高，认为其易于使用，并报告在干预后和1个月随访时状态动机有显著增加（d = 0.49）。这些初步结果令人鼓舞，表明在这一领域有必要开展进一步的工作。
