Seven items assess the extent to which a consumer perceives a specific advertisement as deceptive in its environmental claims — through vague, exaggerated, incomplete, or false green information. Schmuck, Matthes, and Naderer (2018) developed the scale by adapting five items from Chen and Chang (2013) and adding two further items. The scale was applied in Studies 1 and 2 using U.S. and German consumer samples respectively.
7-point Likert (1=strongly disagree, 7=strongly agree)
Full scale items shown. Always cite the original source when using this scale in research.
Alpha was .93 in Study 2 (German sample). CFA confirmed that this scale and the brand nature evocation scale loaded on separate factors, supporting discriminant validity. Items 1 and 2 contain the phrase 'in its environmental features,' which may be ambiguous; users may wish to consider clearer wording. Items 6 and 7 were added by Schmuck et al.; the original five items came from Chen and Chang (2013).
