How it works
This uses only the 10-item IPIP representation of Factor I (Surgency or Extraversion) in the Goldberg (1992) Big-Five factor markers. Five positively keyed items use responses 1–5; five negatively keyed items use 6 minus the response. All ten values are summed, giving a possible total of 10–50. Any missing response hides the total; no missing values are filled in. The order follows the Extraversion items in the official 50-item example.
