Toronto, Aug 24 - Married couples, beware of Faceboook. It triggers jealousy in your spouse.

The more time you spend surfing this social networking website, the more jealous your partner feels, says a new Canadian study.

The study also finds that the need for popularity drives young people to disclose more personal information on Facebook than they normally would reveal.

In their study, Emily Christofides and Amy Muise of the University of Guelph near Toronto say Facebook use leaves many triggers for jealousy in your partner.

Says lead author Amy Muise,'You check your partner's (Facebook) page and you see a post from someone you don't know that says, 'It was great seeing you last night'.

'Even though it could be something very innocent, it can easily be interpreted another way.''Once triggered, she says, Facebook-fuelled jealously leads your spouse to dig for more information about your chat partners, thus setting in motion a vicious cycle.

If it is not stopped immediately, your relationship may soon go from 'married'' to 'complicated'' to divorced.

According to the study, though the majority of people (76 per cent) are concerned about privacy and information control, they still disclose a great deal of personal information in online environments.

'They share and show more about themselves than they might in other social settings. We wanted to find out if different psychological factors are involved in that behaviour,'' says co-author Christofides.

This includes information about birthdays, email addresses, hometowns, school and degree major, and intimate photographs, she says.
