The GZTS (38) is a factor-based personality questionnaire consisting of 300 items, 30 for each of the 10 GZTS scales. For each item, participants choose between ‘yes,’ ‘no,’ and ‘?.’ Any scale with more than three ‘?’ responses was considered missing, a procedure suggested by Guilford and Zimmerman (42). Therefore, small variations in the number of participants will be seen in the analyses for different scales. Raw scores range from 0 to 30.
