The BFI228 is part of the study on personality and relationship satisfaction (Luo, 2005). The participants were 228 undergraduate students at a large public university in the US. The data were participants' self ratings on the 44 items of the Big Five Inventory (John, Donahue, & Kentle, 1991). These items are Likert variables: disagree strongly (1), disagree a little (2), neither agree nor disagree (3), agree a little (4), and agree strongly (5).

The variables were ordered such that indicators of the same factor are grouped together. Note that reverse-coded items are denoted by '_R'.
V01 to V08 are variables for the factor extraversion: talkative, reserved_R, fullenergy, enthusiastic, quiet_R, assertive, shy_R, and outgoing.
V09 to V17 are variables for the factor agreeableness: findfault_R, helpful, quarrels_R, forgiving, trusting, cold_R, considerate, rude_R, and cooperative.
V18 to V26 are variables for the factor conscientiousness are: thorough, careless_R, reliable, disorganized_R, lazy_R, persevere, efficient, plans, and distracted_R.
