Italy was placed at the bottom of the list with 45, down two points from the July-September period, according to the Nielsen Global Consumer Confidence Index which was measured based on an online survey of more than 30,000 consumers in 60 nations worldwide. A reading above 100 on the index means optimists outnumber pessimists.
India posted the highest score for three consecutive quarters. Its index rose to 129 points in the fourth quarter from 126.2 points three months earlier, Nielsen Company said.
The United States, China and Japan saw their index drop by two points to 106, four points to 107 and four points to 73, respectively.
The comparable figure stood at 98 for Germany, up one point from the previous quarter; and 94 for Britain, up one point from three months earlier.
Shin Eun-hee, head of Nielsen Korea, said: "Despite the government's stimulus measures, South Korea's consumer sentiment worsened during the last quarter, an indication that the country's economy may be mired in a protracted slump."
