“…Because we were interested in three out of the four temperament dimensions and none of the character dimensions, we administered only 55 items from the TCI-125 (i.e., items that comprised the NS, HA, and RD scales). 1 The TCI-125 has been used in numerous previous studies (Akiskal et al, 2005;Picardi, Toni, & Caroppo, 2005;Smith, Duffy, Stewart, Muir, & Blackwood, 2005). This scale correlates with other related measures of temperament (Akiskal et al, 2005), has acceptable internal consistencies (Chakroun-Vinciguerra, Faytout, Pèlissolo, & Swendsen, 2005), has the same factor structure as the standard TCI (Chakroun-Vinciguerra et al, 2005), and demonstrates associations with demographic characteristics that are similar to the original questionnaire (Chakroun-Vinciguerra et al, 2005).…”
