The Conformity Scale was developed by Mehrabian and Stefl (1995) as part of a study of the interrelations among loneliness, shyness, and conformity. If you use the Conformity Sale, be sure to read the Mehrabian and Stefl article for additional background information. You should find analyses of loneliness, shyness, and conformity in terms of the PAD Temperament Model informative. Also, Mehrabian's (1997) theoretical analysis of traits that are approximately related to affiliation and sociability (i.e., sensitivity to rejection, empathy, dependency, conformity, popularity, loneliness, and shyness) is most relevent in understanding the present conformity scale.
