Summary
Perceived injustice (PI) is prevalent in individuals with pain, affecting over 33% in most studies. PI is strongly linked to psychological factors, pain experiences, and quality of life, highlighting its importance in pain management.
Area of Science:
- Pain research
- Psychology
- Health sciences
Background:
- Perceived injustice (PI) is a cognitive appraisal of loss, blame, unfairness, or irreparability following an injury.
- PI is increasingly recognized for its contribution to the experience and burden of chronic pain.
Approach:
- A systematic review and meta-analysis was conducted.
- Searched Web of Science, PubMed, and Embase for relevant cross-sectional and cohort studies.
- Analyzed prevalence of PI and associated factors in pain populations, with subgroup analyses to address heterogeneity.
Key Points:
- The prevalence of PI in people with pain ranged widely from 23% to 77%.
- Significant associations were found between PI and pain catastrophizing, PTSD, anger, anxiety, depressive symptoms, and various functioning domains.
- Factors like pain acceptance and academic/emotional/mental/physical functioning showed inverse relationships with PI.
Conclusions:
- PI affects at least 33% of individuals with pain, underscoring its clinical significance.
- Strong evidence supports the association of PI with psychological, pain-related, and quality of life factors.
- Associations between PI and personal, injury, or recovery characteristics were generally not significant.

1.7K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

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—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.

01:25Analgesia and Pain Management
694
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...

01:14Fundamental Attribution Error
12.9K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
