New study links TV to depression

Unhappy people glue themselves to the television 30 percent more than happy people.

The finding, announced on Thursday, comes from a survey of nearly 30,000 American adults conducted between 1975 and 2006 as part of the General Social Survey.

While happy people reported watching an average of 19 hours of television per week, unhappy people reported 25 hours a week. The results held even after taking into account education, income, age and marital status.

The researchers are not sure, though, whether unhappiness leads to more television-watching or more viewing leads to unhappiness.

In fact, people say they like watching television: Past research has shown that when people watch television they enjoy it. In these studies, participants reported that on a scale from 0 (dislike) to 10 (greatly enjoy), TV-watching was nearly an 8.

But perhaps the high from watching television doesn't last.

"These conflicting data suggest that TV may provide viewers with short-run pleasure, but at the expense of long-term malaise," said researcher John Robinson, a sociologist at the University of Maryland, College Park.
