Description on p. 854:

“McCroskey, Beatty, and colleagues (1985) developed the PRCA-24 as a trait-based measure to measure communication apprehension in the four general communication situations: public speaking, group interactions, meetings, and dyadic interactions. Given that FLAMOS specifically refers to interpersonal interactions, the six-item interpersonal subscale was used to measure communication apprehension between dyads (see Appendix A). Participants answered each question on a 5-point Likert-type scale ranging from 1 (strongly disagree) to 5 (strongly agree). Inconsistent with previous research, the scale did not exhibit adequate internal reliability (Cronbach’s α =.55). A principal components factoring with varimax rotation revealed that the three positively worded items and the three negatively worded items loaded on two separate factors. It is possible that when translated into Spanish, the negatively worded items did not represent the same construct to participants as the positively worded items. Thus, the three positively worded items were averaged to create a variable,
which is henceforth labeled communication apprehension. The three items did not show good internal reliability (Cronbach’s α = .67), but were retained to represent the communication apprehension construct.”
