PSI and Attitude Certainty -- cleaned up.sav

A survey was conducted through Amazon MTurk to a diverse sample of adults (<i>N</i> = 404) from all over the United States.<br><b>P</b><b>SI Processing</b><b>.</b> Participants responded to a 14-item adapted version of the PSI-Process Scale (Schramm &amp; Hartmann, 2008). The PSI-Process Scale measures cognitive, affective, and behavioral dimensions of PSI. An example item was: "I carefully followed the behavior of Donald Trump" and was measured on a Likert scale of 1 to 7 (1= <i>not at all</i>, 7= <i>very much so</i>). As suggested by Wong, Lookadoo, and Nisbett (2017), the items were averaged to create a PSI index in which higher scores indicated favorable attitudes toward Trump. <b>Attitudes toward Trump</b><b>. </b>The 9-item Trump attitude scale (Choma &amp; Hanoch, 2016) was administered to assess attitudes toward Donald Trump. Participants indicated agreement on a scale 1 to 7 (1= <i>completely disagree</i>, 7= <i>completely agree</i>). An example item included "Donald Trump has the American people's best interests in mind." All items were averaged to create an index in which higher scores indicated favorable attitudes toward Trump. <b>Attitude certainty</b><b>. </b>Participants were asked to report the degree to which they were certain of their attitudes toward Trump using the attitude certainty scale adapted from Petrocelli et al. (2007). The scale consisted of four attitude clarity items and three attitude correctness items on a scale 1 to 7 (1= <i>very uncertain</i>, 7= <i>very certain</i>). Petrocelli et al. (2007) posit, "clarity and correctness can be measured separately and statistically differentiated in their contributions to attitude certainty" (p. 33). An example item for attitude clarity was "To what extent is your attitude toward Donald Trump clear in your mind?"and an example item for attitude correctness was "How certain are you that your attitude toward Donald Trump is the correct attitude to have?" The items were compiled into indices of each. <b>Demographics</b><b>. </b>Demographic data were collected at the end of the survey. Participants were asked to indicate their gender, age, ethnicity, education level, and estimated annual household income.
