خلاصه	The UCLA Loneliness Scale is a widely used instrument for measuring subjective feelings of loneliness and social isolation. Developed by Daniel Russell in the late 1970s, the scale measures the discrepancy between desired and actual social relationships. The UCLA LS has become the gold standard in loneliness research and is used across clinical, epidemiological, and social psychology studies worldwide.	The Toronto Empathy Questionnaire (TEQ) is a 16-item self-report measure of empathic ability and emotional responsiveness to others' emotions. Developed by Randy Spreng and colleagues in 2009, the TEQ captures affective empathy—the capacity to feel and share another person's emotions—rather than cognitive perspective-taking. The scale has become widely used in social, clinical, and neuroscience research examining individual differences in emotional empathy and its correlates with mental health, prosocial behavior, and brain structure.
