ABSTRACT This study tests an expanded theory of planned behavior model (TPB) that includes motives from uses and gratifications (U&G) to predict intentions to use digital music streaming services as well as the time spent listening (TSL). When examined alone, the traditional TPB components were positive predictors of intentions to use music streaming services. Adding the U&G motives increased the explained variance but only entertainment/mood management and social interaction factors were positive predictors of intentions. Using the traditional TPB to predict TSL revealed a different result. Only the attitudes component from the TPB was significant. After adding U&G motives to the analysis, only attitudes and social interaction emerged as positive predictors of TSL. This study highlights fundamental differences between what drives intentions to use music streaming services as compared to the time they spend using such services. It also indicates that U&G motives can be useful additions when expanding the TPB in the context of new technologies.

整合计划的行为，使用和满足的理论以了解音乐流的意图和行为

摘要这项研究测试了计划行为模型（TPB）的扩展理论，其中包括使用和满足（U＆G）的动机来预测使用数字音乐流服务的意图以及所花费的时间（TSL）。当单独检查时，传统的TPB组件是使用音乐流服务的积极预测指标。添加U＆G动机会增加解释的差异，但只有娱乐/情绪管理和社交互动因素才是意图的积极预测因子。使用传统的TPB预测TSL会得出不同的结果。城规会的态度成分很重要。在将U＆G动机添加到分析中之后，只有态度和社会互动才成为TSL的积极预测因素。这项研究强调了推动使用音乐流服务的意图与使用音乐流服务的时间之间的根本差异。它还表明，在新技术的背景下扩展TPB时，U＆G动机可能是有用的补充。
