Results from the Aversive Impact Index [AII] assessing (a) psychological needs and (b) mood from pre- and post-social interaction between control and ostracism conditions. Neither psychological needs nor mood differed between conditions prior to the social interaction. Following the social interaction, (a) psychological needs decreased significantly in the ostracism condition (p = .001). (b) Mood significantly increased from pre- to post- in the control condition (p = .03), and marginally significantly decreased in the ostracism condition (p = .08).
