“…To address the six hypotheses, a coding scheme of 11 measures was developed with the categories of all measures designed to be exhaustive and mutually exclusive (Kaid & Wadsworth, 1989;Krippendorff, 1980), including 1) relevance categorized as relevant=irrelevant (the details of the talk were clearly connected to the investigation and applicable to the participants' assigned issue); 2) primary focus of talk (the details of the talk indicated the participant was seeking a) support, affirmation, and reassurance, or b) to share his or her thoughts, rationale, and reasons) categorized as either reassurance, advocacy, both, or can't tell=no indication; 3) position of conversational partner (the details of the talk indicated the other(s) engaged in the conversation had an a) differing or b) similar viewpoint) categorized as opposite, same, or can't tell=no indication, based on comparing conversation content associated with the conversation partner to the position of the participant as indicated on the file; 4) presence of attack (the details of the talk indicated the participant a) was, or b) was not challenged on his or her position) categorized as presence=absence of attack, or can't tell=no indication (e.g., Pfau et al, 1997Pfau et al, , 2005Pfau et al, , 2009; 5) tone of the talk (the details of the talk indicated a) positive and favorable, or b) negative and unfavorable thoughts or arguments) categorized as positive, negative, or can't tell=no indication (Compton & Pfau, 2004;Pfau et al, 2005); 6) issue referenced in talk (the details of the talk contained mentions of the participants' a) assigned issue, or b) a related issue) categorized as talk on assigned issue, talk on related issue, both, or can't tell=no indication (McGuire, 1964;Parker et al, 2012); 7) number of arguments in talk attributed to the conversational partner; 8) number of arguments in talk attributed to the participant; 9) inoculation message material (the details of the talk contained information and arguments from the inoculation message associated with the participants' assigned issue and stance) categorized as repetition of inoculation message, new arguments not in inoculation message, both, or can't tell=no indication based on comparing conversation content to a list of arguments contained in the original inoculation message associated with the participant's assigned issue; 10) certainty or confidence expressed in talk (the details of the talk used language that was a) certain, firm, and strong, b) expressive, but neither firm nor certain, or c) hesitant, ambivalent, and uncertain) categorized as high, moderate, low, or can't tell=no indication (e.g., Pfau et al, 2004Pfau et al, , 2005; and 11) combativeness expressed in talk (the details of the talk contained a) conflicting viewpoints and arguments, b) were mildly conflicting, or c) were one-sided) categorized as high, moderate, low, or can't tell=no indication (e.g., Ivanov et al, 2012;Lumsdaine & Janis, 1953).…”
