This incorporated two well-validated personality inventories: the IPIP and the NEO-FFI. The IPIP Big-Five Factor markers is a 50 or 100-item inventory that can be freely downloaded from the internet for use in research [66]. The current study made use of the 50-item version consisting of 10 items for each of the Big-Five personality factors: Extraversion (E), Agreeableness (A), Conscientiousness (C), Emotional Stability (ES) and Intellect (I). For each of the items, which are in sentence fragment form (e.g., "Am the life of the party"), "I" was added at the beginning so that the items would be easier to read, and more closely match the other inventories used. Participants were requested to read each of the 50 items and then rate how well they believed it described them on a 5-point scale (very inaccurate to very accurate). The NEO Five Factor Inventory [67] is a 60-item inventory consisting of 12 items each for the 5 factors: Neuroticism (N), Extraversion (E), Openness (O), Agreeableness (A) and Conscientiousness (C). Participants were asked to mark each item on a 5-point scale (strongly disagree to strongly agree) according to how well it described them.
