Existing literature outlines mothers' negative experiences with breast pumps, yet a gap exists of which breast pump characteristics are important to mothers. Identifying which breast pump characteristics are important to breast pumping mothers, and any variation between mothers who do or do not work outside of the home, will help identify user needs. A survey collected information on mothers' experiences with breast pumps and impressions of their characteristics. Latent Class Analysis (LCA) was used to determine whether there were possible groupings of impressions of these characteristics. The LCA identified a two-class model with mothers' age as a significant covariate. Portability, ease of use, low-weight, fast milk extraction, comfortability, low-noise, and discreet were all found to be important to one group of mothers, while only portability, ease of use, fast milk extraction, and comfortability were found to be important to another group of mothers. Mothers' work status was not a significant covariate but did predict class membership when considered as a grouping variable in conjunction with age. Breast pumping mothers' needs were found to differ based on their work status and age together, and collecting and considering these different needs is vital to creating redesigns that improve mothers' breast pumping experience.

以母亲为中心的吸乳器评估。

现有文献概述了母亲在使用吸乳器方面的负面经历，但仍然存在着差距，这对母亲而言很重要。识别哪些吸奶特征对吸乳母亲很重要，以及在家中工作或不工作的母亲之间的差异，将有助于确定用户的需求。一项调查收集了有关母亲使用吸乳器的经历及其特征印象的信息。潜在类别分析（LCA）用于确定是否存在这些特征的印象分组。LCA确定了一个两级模型，其中母亲的年龄是重要的协变量。便携性，易用性，低重量，快速排乳，舒适性，低噪音和谨慎对一组母亲都很重要，而只有便携性，易用性，快速提取牛奶和舒适性对另一组母亲很重要。母亲的工作状态不是显着的协变量，但是当与年龄结合使用时，确实可以预测班级成员身份。人们发现，根据她们的工作状态和年龄，吸乳妈妈的需求会有所不同，因此收集和考虑这些不同的需求对于进行重新设计以改善妈妈的吸乳体验至关重要。
