A three-item unipolar scale measuring the degree to which a piece of information — such as an online review — is perceived as helpful, useful, and informative. Items are single adjectives rated on a seven-point scale. The scale is general and can be applied across a wide range of informational stimuli. Moore (2015) used it in Study 5 with 186 online panel respondents, measuring perceived review informativeness in the context of explained actions versus reactions for hedonic versus utilitarian products. The source of the scale was not identified. Alpha = .85 indicates good internal consistency. The scale should be distinguished from the Ad Informativeness Scale (id:594), which is specific to advertising stimuli.
