Note: Tests used individuals (n) if both friends in the dyad reported for the Domain. Statistics are presented as absolute values. See Table 3 for direction of significant group differences.

I = Introvert; E = Extravert; bold font indicates personality of the friends compared; e.g., E-E / I-E indicates matched extravert friends were compared to introverted friends in mixed dyads.

Females were dummy coded as 0, males as 1.
