The Role of Personality Traits and Values in Perceived Friendship Quality: The Dyadic Approach

This study using dyadic approach, focused on the impact of personality traits and basic human values on the synchrony and the average level of perceived friendship quality between dyads. We used the Friendship Quality Questionnaire to measure the perceived friendship quality levels of the involved parties, the 50-item IPIP version of Big Five Questionnaire to quantify the individual personality traits and a Short Swartz Values Survey to characterize different basic human values. Two aggregated measures were defined based on the score of friendship quality of each party of the friends. The level of friendship quality was defined as the sum of perceived quality of two persons involved in the friendship. The synchrony of friendship quality was defined by subtracting the perceived quality of one party from the other in the friendship. The level and the synchrony of each personality traits and each basic human value between dyads were quantified in a similar way. Several linear regressions were conducted in a two-step process to examine the correlation between personality traits and friendship quality and the correlation between basic values and friendship quality both at the dimension of general levels and synchrony. The results showed a significant positive effect of agreeableness on the level of friendship quality and a significant positive effect of agreeableness on the synchrony of friendship quality. Our findings highlight the association between personality and the perceived quality in dyadic relationships.
