In order to reduce the risk of chronic diseases health authorities recommend restricting fat intake to 30% of the total energy uptake. However, fat intake in Belgium is much higher warranting interventions aimed at reducing fat intake. Tailored interventions have shown to be promising; however, studies on effectiveness of interactive computer-tailored systems are needed. We investigated the acceptability and feasibility of a recently developed interactive computer-tailored fat reduction intervention. Differences in the reported acceptability and feasibility according to demographic and stages of change were explored. Participants (n = 220) completed a computerized questionnaire, and received a personal fat intake advice, which was almost immediately displayed on screen. They also completed an evaluation questionnaire, during and after they ran the tailored program, with questions on the quality, user-friendliness and applicability of the program. Participants rated the program positively on all aspects. No significant differences in acceptability and feasibility scores were found according to sex, education levels and computer literacy. Although several significant differences were found between age groups and stages of change (oldest group, contemplators and preparators were more positive about the program), the importance of these differences is probably not great, since acceptability and feasibility scores for the different age groups and stages of change were always very high. These results suggest that the computer-tailored intervention is an acceptable and feasible tool for reducing fat intake in a general population in Belgium.
为降低慢性病风险，卫生当局建议将脂肪摄入量限制在总能量摄入的30%以内。然而，比利时的脂肪摄入量要高得多，因此需要采取旨在减少脂肪摄入的干预措施。量身定制的干预措施已显示出前景；然而，需要对交互式计算机定制系统的有效性进行研究。我们调查了最近开发的交互式计算机定制减脂干预措施的可接受性和可行性。探讨了根据人口统计学和行为改变阶段报告的可接受性和可行性的差异。参与者（n = 220）完成了一份计算机化问卷，并收到一份个人脂肪摄入建议，该建议几乎立即显示在屏幕上。他们还在运行定制程序期间和之后完成了一份评估问卷，其中包含有关该程序的质量、用户友好性和适用性的问题。参与者对该程序的各个方面都给予了积极评价。根据性别、教育水平和计算机素养，未发现可接受性和可行性得分存在显著差异。尽管在年龄组和行为改变阶段之间发现了一些显著差异（最年长的组、沉思者和准备者对该程序更为积极），但这些差异的重要性可能不大，因为不同年龄组和行为改变阶段的可接受性和可行性得分一直都很高。这些结果表明，计算机定制干预措施是比利时普通人群减少脂肪摄入的一种可接受且可行的工具。
