Effects of Sugary Drinks Counter-marketing Messages

We will assess intentions to consume sugary drinks using 2 items: "In the next week, I plan to drink sugary drinks like sodas, sports drinks, or fruit drinks," and "In the next week, I am likely to drink sugar-sweetened beverages like sodas, sports drinks, or fruit drinks". Response options to both items will use a 5-point Likert scale: the first item's response options will range from "definitely not" (1) to "definitely yes" (5), and the second item's response options will range from "not at all likely" (1) to "extremely likely" (5). We will average responses to the 2 items.

Item: "These messages discourage me from wanting to drink sugary drinks." This variable will be measured on a 5-point Likert scale ranging from "not at all" (1) to "a great deal" (5).

Item: "How do these messages make you feel about drinking sugary drinks?" This variable will be measured on a 5-point Likert scale ranging from "extremely positive" (1) to "extremely negative" (5).

We will examine anticipated social interactions by asking, "How likely are you to talk about these messages with others in the next week?" This item will be scored on a 5-pt Likert scale ranging from "not at all likely" (1) to "extremely likely" (5).

We will examine attitudes toward sugary drink companies by asking, "How do you feel about companies that make sugary drinks?" This item will be scored on a 5-pt Likert scale ranging from "dislike them a lot" (1) to "like them a lot" (5).

We will examine the extent to which participants perceive the messages as contributing to obesity stigma by asking 3 items: "These messages promote negative attitudes about people who have overweight or obesity," "These messages increase blame towards people for being overweight," and "These messages make obesity seem like a much simpler issue than it really is." Each item will be scored on a 5-point Likert scale from "not at all" (1) to "a great deal" (5). We will average responses to these items.

We will examine psychological reactance to the messages by asking 3 items: "These messages are trying to manipulate me," "These messages are overblown" and "How much do these messages make you feel angry?" Each item will be scored on a 5-point Likert scale from "not at all" (1) to "a great deal" (5). We will average responses to these items, assuming sufficient internal consistency (alpha>=.70).
