Abstract
Purpose
This paper aims to examine the effects of qualifying language, functional ingredient, ingredient familiarity and inferences of manipulative intent (IMI) on the likelihood that consumers make stimulus-based inferences about the level of scientific support for health claims on food.
Design/methodology/approach
An advertisement copy test for a fictitious product bearing a caries risk-reduction claim has been conducted. The test design comprises three claim conditions, each corresponding to one of the sufficient levels of support for nutrient-health relations within the World Health Organization (WHO)-framework.
Findings
The claim conditions have affected the likelihood of making stimulus-based inferences, which is lower for high-level-of-support claims as opposed to low-level-of-support and moderate-level-of-support claims. No effect of ingredient familiarity has been observed. The effect of the functional ingredient featured is significant at the 10 per cent-level. IMI has a negative effect on the likelihood of making a stimulus-based inference.
Research limitations/implications
The survey relies on a demographically homogeneous sample.
Practical implications
Examining the likelihood of stimulus-based inferences about health claim substantiation is essential for assessing the effectiveness of claim formulations and for addressing resulting miscommunication.
Originality/value
The current paper addresses the research gap on consumer ability to identify the level of support for health claims within the European context.
