The interpersonal attraction scale consisted of 15 items
measuring personal desirability. Taken from the 1974 survey constructed by McCroskey and
McCain, this survey was designed in three parts: social attraction ( = .84), physical attraction (
= .86), and task attraction ( = .81). McCroskey and McCain’s response sets were all Likert
scales which were not altered (1= strongly disagree; 5 = strongly agree).
