Optimism is prospectively associated with superior health outcomes in cardiac patients, making it an attractive target for well-being interventions in this population. However, optimism measured by the Life Orientation Test-Revised (LOT-R) has largely been considered a static, dispositional construct. Among 125 patients with a recent acute coronary syndrome who received a positive psychology intervention, we assessed the properties of a modified LOT-R that changed the timeframe of items from general dispositional statements to queries about 'right now.' We aimed to learn whether this modified LOT-R was more dynamic than the original LOT-R via administration of both instruments at three timepoints over the 16-week study period. Contrary to our hypothesis, this modified LOT-R showed no greater change in mean score or intra-individual variance than the original LOT-R over 16 weeks. This suggests that simply changing the timeframe of the LOT-R may not facilitate assessment of more state-like optimism in medical patients.
乐观情绪与心脏病患者更好的健康结果呈前瞻性关联，这使其成为该人群幸福感干预的一个有吸引力的目标。然而，通过修订后的生活取向测试（LOT-R）测量的乐观情绪在很大程度上被视为一种静态的、特质性的结构。在125例近期患有急性冠状动脉综合征并接受积极心理干预的患者中，我们评估了一种修改后的LOT-R的特性，该测试将项目的时间框架从一般特质性陈述改为关于“此刻”的询问。我们旨在通过在16周的研究期间的三个时间点同时使用这两种工具，了解这种修改后的LOT-R是否比原始的LOT-R更具动态性。与我们的假设相反，在16周内，这种修改后的LOT-R在平均得分或个体内方差方面的变化并不比原始的LOT-R更大。这表明，仅仅改变LOT-R的时间框架可能无法促进对医学患者中更具状态性的乐观情绪的评估。
