One way in which people may cope with sadness is to seek positive social contact. We examined whether subtle reminders of Facebook increase positive mood and thus attenuate the interest in social activities that is typically enhanced by sad mood induction. Participants watched either a loss-related sad or neutral video and were afterwards presented with either a Facebook, positive (sun) or neutral (Word) icon. We then examined their mood and their desire to engage in social activities as well as their feeling of belonging. The presentation of the Facebook icon increased feelings of belonging, but it did not influence participants’ other responses to the sad video. Participants reported more negative mood and a greater desire to engage in social activities after the sad (vs. control) video regardless of the icon condition. The results suggest that the activation of thoughts about Facebook can enhance users’ feeling of belonging; however, this effect might not be sufficient to facilitate coping with loss-related sadness.
