概括
疼痛灾难性得分随着疼痛强度而变化,表明它们并非无上下文. 了解参考疼痛对于准确解释疼痛灾难化 (PCS) 评分至关重要.
科学领域:
- 心理学 心理学 心理学
- 疼痛研究 疼痛研究
- 临床评估 临床评估
背景情况:
- 疼痛灾难化被广泛研究,但对夸大反应与比例反应缺乏明确的定义.
- 当前的评估往往缺乏参考疼痛,使疼痛背景对灾难性思维的影响不清楚.
研究的目的:
- 为了评估不同参考疼痛场景的疼痛灾难性的一致性.
- 将高疼痛灾难化描述为相对于特定疼痛强度的夸张反应.
主要方法:
- 在标准和特定的参考疼痛场景下,228名成年人完成了疼痛灾难化量表 (PCS).
- 类内相关性评估了跨情况的一致性;混合线性模型检查了PCS-参考疼痛关系.
主要成果:
- 在PCS中,表现出高度的跨情况一致性 (ICCs = 0.79-0.84).
- 然而,PCS得分与参考疼痛强度 (R=0.74,p<0.0001) 有显著差异,疼痛解释了40%的得分变化.
- 高的灾难性值取决于疼痛强度的背景,没有显著的性别差异.
结论:
- 疼痛灾难化度量 (PCS) 评分不是无上下文的,不应该被这样解释.
- 发表的PCS切割点的变化可能受到不同的参考疼痛环境的影响,因此需要对得分进行上下文化以获得准确的解释.

Pain
1.2K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Nociception
33.0K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Analgesia and Pain Management
1.5K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Regression Toward the Mean
6.8K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Lazarus's Cognitive Appraisal Theory
1.6K
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.

Beck's Cognitive Therapy
328
Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.
