现有的信息技术（IT）使用理论提出了用户的行为意图作为其IT使用行为的主要预测。然而，经验证据显示，这种关联只有低到中等的效应量。我们称这种不一致的“意图行为差距”，并认为，更清楚地了解这种差距需要更深入的理论研究的条件下，意图可能会或可能不会影响行为。借鉴最近的态度理论研究在社会心理学中，我们区分两种类型的态度-强与弱-并建议，意图行为协会可能持有强烈的态度的用户，但很可能是弱的态度。使用的阐述可能性模型，我们提出了两个维度的态度强度相关的IT使用情况下-个人相关性和相关的专业知识-和理论化他们温和的意图行为协会在一个积极的方式。在利沃夫市政厅，乌克兰政府雇员之间的文件管理系统的使用纵向实地调查结果支持我们的理论假设。我们的研究结果的理论和实践意义进行了讨论。
Extant theories of information technology (IT) usage present users' behavioural intention as the primary predictor of their IT usage behaviour. However, empirical evidence reveals only a low-to-medium effect size for this association. We call this inconsistency the 'intention-behaviour gap', and argue that a clearer understanding of this gap requires a deeper theoretical examination of the conditions under which intentions may or may not influence behaviour. Drawing on recent attitude theoretic research in social psychology, we distinguish between two types of attitudes - strong versus weak - and suggest that the intention-behaviour association may hold for users with strong attitudes but is likely to be weaker for those with weak attitudes. Using the elaboration-likelihood model, we propose two dimensions of attitude strength relevant to the IT usage context - personal relevance and related expertise - and theorise them to moderate the intention-behaviour association in a positive manner. Results from a longitudinal field survey of document management system usage among governmental employees at L'viv City Hall, Ukraine support our theoretical hypotheses. Theoretical and practical implications of our findings are discussed.
