摘要

目的:本研究旨在通过使用五个预定义构念开发的研究模型,检查用户对基于说服性信息系统的儿童保健干预的看法。方法:该研究于2017年6月在阿曼盲法进行。使用五个预定义的构念,开发了一个研究模型。这些构念被用作潜在变量,以检验它们对用户使用有说服力的儿童保健干预措施的感知和意图的可能影响。一份结构化的问卷被验证并分发给150名参与者,以了解他们的看法。采用因子负荷和计算方差来保证研究模型的效度和信度。此外,采用Cronbach 's Alpha测量内部一致性和信度。结果:每个项目(每个构念)的因子负荷和计算方差分别大于0.700和0.500。平均方差提取(AVE)值均在0.635以上。所有相关的判别效度都低于理想的html值0.90。路径系数和外部负荷分析表明,感知有用性(p<0.001)、干预内容(p<0.050)、感知可信度(p<0.050)和感知有用性(p<0.050)对干预使用意愿有显著影响。结论:研究结果支持所研究的研究模型,并表明用户认为干预具有说服力,因为它是可信的,其内容是有意义的。当用户认为一种干预是可信和有用的,它就会培养他们在现实生活中实际使用它的意图。

Users’ Perceptions on a Persuasive Information System-Based Intervention for Child Healthcare: A Trial Study
Objective: This study aimed to examine users’ perception on a persuasive information system-based intervention for child healthcare through a research model that was developed using five pre-defined constructs. Methods: The study was carried out at Blinded, Oman in June 2017. Using five pre-defined constructs, a research model was developed. The constructs were used as latent variables to examine their likely impact on users’ perceptions and intentions to use a persuasive intervention for child healthcare. A structured questionnaire was validated and distributed among 150 participants to access their perceptions. Factor loadings and calculated variances were used to ensure validity and reliability of the research model. In addition, Cronbach’s Alpha was employed to measure the internal consistency and reliability. Results: Factor loadings and calculated variances for each item (per construct) were greater than 0.700 and 0.500 respectively. The Average Variance Extracted (AVE) values were above 0.635. The discriminant validity of all the correlations was below the desirable HTMT value of 0.90. Analyses of path coefficients and outer loadings indicate that Perceived Usefulness (p<0.001), Content of Intervention (p<0.050), Perceived Credibility (p<0.050) and Perceived Usefulness (p<0.050) can have a significant influence on Intention to Use the Intervention. Conclusions: The findings support the studied research model and indicate that users perceive an intervention to be persuasive given that it credible and its content is meaningful. When users perceive an intervention as being credible and useful, it develops their intention to actually use it in real life.
