associated with anticipatory processing and social anxiety symptoms. Consequently, the purpose of the current study was to develop and preliminary validate a measure specifically designed to measure positive beliefs about AP. It was expected that the Positive Beliefs about Anticipatory Processing Questionnaire (PB- APQ) would exhibit sound psychometric properties. In addition to adequate reliability, this measure was expected to exhibit adequate criterion validity, as it was expected to be significantly associated with measures of social interaction anxiety and anticipatory processing. The PB-APQ was also expected to exhibit adequate incremental validity, by predicting variance in anticipatory processing and social interaction anxiety after controlling for other metacognitive variables (such as positive beliefs about worry or rumination). We also expected that the PB-APQ would exhibit 5

Anticipatory processing and metacognition discriminative validity such that it would not explain unique variance in depressive symptoms, after controlling for social interaction anxiety and other metacognitive variables. Finally, it was anticipated that anticipatory processing would mediate the relationship between positive beliefs about anticipatory processing and social anxiety symptoms. Method Participants Participants were 301 undergraduate students at the University of Ioannina, of whom 40 (13.3%) were male and 261 (86.7%) were female. On average, participants were 20.0 years old (S.D. = 1.8, range: 18-37, two did not report their age), single (95.7%), and Christian Orthodox (93.4%). All students were White Europeans, and completed Greek-language versions of all measures. Measures Positive Beliefs about Anticipatory Processing Questionnaire (PB-APQ) Our new 21-item PB-APQ uses a 5-point Likert-type rating scale, ranging from 1 ( disagree ) to 7 ( agree ). PB-APQ items were rationally generated and designed to exclusively assess the positive beliefs that individuals hold about the benefits of engaging in anticipatory processing. Specifically, items assessed recent social interactions, thoughts about the interaction before it occurred, and motivation for ruminating over the anticipated social interaction. After 1 item was removed because it did not load significantly on the single factor, the 20 remaining items are listed in the Appendix. Information on psychometric properties is provided below. Social Interaction Anxiety Scale (SIAS; Mattick & Clarke, 1998) The SIAS is a 20-item measure used to assess anxiety related to social interactions with various partners. Items are rated on a 0-4 Likert-type scale. Past research has shown that the SIAS displays good to excellent internal consistency, good construct validity, and that it converges with other measures of social anxiety (for a review, see Heimberg & Becker, 2002). The three reverse-scored items were omitted based on evidence suggesting that removing these items improves the psychometric properties of the scale (Rodebaugh, Woods, & Heimberg, 2007). In the current sample, Cronbach’s alpha for the straightforward items was good ( α = .90).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
