摘要目的:探讨信任、感知收益与感知风险对产妇互联网居家护理服务使用意愿的影响。方法:本研究为横断面研究。于2020年6—8月采用方便抽样法选取在温州市某三甲医院产科住院的268名产妇为研究对象。采用—般情况调查表，居家护理服务的信任、感知收益、感知风险与使用意愿问卷对其进行调查。采用多重线性回归分析进行影响因素分析，采用结构方程模型构建路径关系。结果:共回收有效问卷256份。256名产妇互联网居家护理服务使用意愿总分为（12.32±2.20）分。多重线性回归结果显示，家庭人均月收入、常用护理服务来源、信任、感知收益、感知风险是产妇互联网居家护理服务使用意愿的影响因素（ P<0.05），可解释总变异的49.6%。中介效应分析结果显示，感知收益、感知风险在信任与使用意愿之间均存在部分中介效应，分别占总效应的47.8%与5.1%。 结论:政府及服务提供方应重视信任对产妇互联网居家护理服务使用意愿的影响，可通过提升其感知收益、降低其风险忧虑进而提升其使用意愿。

abstractsObjective:To explore the effect of perceived benefits and perceived risk on maternal willingness to use Internet home care services.Methods:This study was a cross-sectional study.From June to August 2020, the convenient sampling method was adopted to select 268 parturient women who were hospitalized in the obstetrics department of a ClassⅢ Grade A hospital in Wenzhou as the research objects. General information questionnaire and questionnaire on trust, perceived benefits, perceived risks and willingness to use home care services were used to investigate them. Multiple linear regression analysis was used to analyze the influencing factors, and the structural equation model was used to construct the path relationship.Results:A total of 256 valid questionnaires were collected. The total score of willingness to use Internet home care services for 256 parturient women was (12.32±2.20) .The results of multiple linear regression showed that family average monthly income, common nursing service sources, trust, perceived benefits and perceived risks were the influencing factors of maternal willingness to use Internet home care services ( P<0.05) , which could explain 49.6% of the total variation.The analysis of the mediation effect showed that perceived benefits and perceived risks had partial mediation effects between trust and willingness to use, accounting for 47.8% and 5.1% of the total effects, respectively. Conclusions:The government and service providers should pay attention to the effect of trust on the willingness to use internet home care services of parturient women and increase their willingness to use it by improving their perceived benefits and reducing their risk and worries.
