概括
优化患者报告结果指标 (PROM) 需要平衡测试负担和临床可靠性. 修改的停止规则,特别是减少最大项目,为加强临床环境中的PROM提供了一个有希望的方法.
科学领域:
- 心理测量 心理测量 心理测量
- 临床评估 临床评估
- 健康 结果 研究 研究 结果
背景情况:
- 患者报告的结果指标 (PROM) 对于临床决策和治疗评估至关重要.
- 然而,PROMs可能会给患者带来重大负担,并且可能缺乏清晰临床解释所需的可靠性.
研究的目的:
- 在NIH工具箱®情感电池中评估计算机化适应性测试 (CAT) 的替代停止规则.
- 评估这些规则对测试负担,评分精度和可靠性的影响.
主要方法:
- 计算机自适应测试 (CAT) 模拟在NIH Toolbox®的负面影响子域内的成人项目库上进行.
- 模拟将原始停止规则 (标准误差<0.3) 与修改后的规则进行比较,包括SE变更规则,固定长度CAT和减少最大项数.

01:20Coping Strategies: Emotion Focused
Emotion-focused coping refers to a set of strategies aimed at managing the emotional impact of stressors, rather than directly addressing their causes. This approach involves altering one's emotional response to stressful situations to reduce their psychological effects. For example, individuals might talk with a friend or engage in activities like journaling to express their feelings. Such actions can help achieve emotional clarity or release, providing the psychological stability needed to...
01:29The Influence of Cognition on Affect
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be interpreted as...
