The Tailored Interventions for management of DEpressive Symptoms (TIDES) program was designed based on social cognitive theory to provide tailored, computer-based education on key elements and self-care strategies for depressive symptoms in persons living with HIV/AIDS (PLWHAs).
Based on an extension of the Technology Acceptance Model (TAM), a cross-sectional design was used to assess the acceptance of the HIV TIDES prototype and explore the relationships among system acceptance factors proposed in the conceptual model.
Thirty-two PLWHAs were recruited from HIV/AIDS clinics. The majority were African American (68.8%), male (65.6%), with high school or lower education (68.7%), and in their 40s (62.5%). PARTICIPANTS spent an average of 10.4 minutes (SD = 5.6) using HIV TIDES. The PLWHAs rated the system as easy to use (Mean = 9.61, SD = 0.76) and useful (Mean = 9.50, SD = 1.16). The high ratings of behavior intention to use (Mean = 9.47, SD = 1.24) suggest that HIV TIDES has the potential to be accepted and used by PLWHAs. Four factors were positively correlated with behavioral intention to use: perceived usefulness (r = 0.61), perceived ease of use (r = 0.61), internal control (r = 0.59), and external control (r = 0.46). Computer anxiety (r = -0.80), tailoring path (r = 0-.35) and depressive symptoms (r = -0.49) were negatively correlated with behavioral intention to use.
The results of this study provide evidence of the acceptability of HIV TIDES by PLWHAs. Individuals are expected to be empowered through participating in the interactive process to generate their self-care plan. HIV TIDES enables information sharing about depression prevention and health promotion and has the potential to reframe the traditional patient-provider relationship.
针对抑郁症状管理的定制干预（TIDES）项目基于社会认知理论设计，旨在为感染艾滋病毒/艾滋病的患者（PLWHA）提供关于抑郁症状关键要素和自我护理策略的定制化计算机辅助教育。
基于技术接受模型（TAM）的扩展，采用横断面设计来评估艾滋病毒TIDES原型的接受度，并探索概念模型中提出的系统接受因素之间的关系。
从艾滋病毒/艾滋病诊所招募了32名PLWHA。大多数是非洲裔美国人（68.8%），男性（65.6%），高中及以下学历（68.7%），年龄在40多岁（62.5%）。参与者使用艾滋病毒TIDES的平均时间为10.4分钟（标准差=5.6）。PLWHA对该系统的评价是易于使用（均值=9.61，标准差=0.76）且有用（均值=9.50，标准差=1.16）。对使用行为意图的高评分（均值=9.47，标准差=1.24）表明艾滋病毒TIDES有被PLWHA接受和使用的潜力。四个因素与使用行为意图呈正相关：感知有用性（r = 0.61）、感知易用性（r = 0.61）、内部控制（r = 0.59）和外部控制（r = 0.46）。计算机焦虑（r = -0.80）、定制路径（r = -0.35）和抑郁症状（r = -0.49）与使用行为意图呈负相关。
本研究结果提供了PLWHA对艾滋病毒TIDES可接受性的证据。预计个人将通过参与互动过程来制定自我护理计划而获得赋能。艾滋病毒TIDES能够实现关于抑郁症预防和健康促进的信息共享，并有可能重塑传统的医患关系。
