Methods to assess ambivalence towards food and diet: a scoping review

“…We identified 54 different attitude objects towards which the ambivalence of participants was assessed in studies included in this review (Supporting Information: Appendix V). The most common objects of attitude towards which authors assessed the ambivalence of participants across included studies were beef or red meat (n = 12), 32,39,41,42,48,56,60,65,68,[72][73][74] chocolate (n = 7), 14,46,47,59,61,73 food or eating (n = 6), 43,[50][51][52][53]63 low-fat diets (n = 5), 35,36,40,44,45 fruits and vegetables (n = 5) 16,36,44,45,65 and fast food or 'junk food' (n = 3). 57,67,74 Some studies included multiple attitude objects.…”

“…The definitions of ambivalence provided by different studies included in this review were consistent with each other, most of them referring to the simultaneous presence of positive and negative evaluations towards an attitude object, with some authors emphasising the similarity in the intensity of these evaluations. 16,32,[36][37][38][39][40][42][43][44][45][46]48,51,52,55,56,58,61,65,67,68,72,73 Similarly, the definitions provided by other studies focused on aspects like the lack of consistency within the individual; the state of holding mixed feelings; or the contradictions experienced in individual attitudes, beliefs or preferences towards an attitude object. 32,49,63,64,66,70 Across studies included in this review, several authors provided definitions for different types of ambivalence, differentiating between potential and felt ambivalence and between intra-component (cognitive or affective) and intercomponent (cognitive-affective) ambivalence.…”

“…32,49,63,64,66,70 Across studies included in this review, several authors provided definitions for different types of ambivalence, differentiating between potential and felt ambivalence and between intra-component (cognitive or affective) and intercomponent (cognitive-affective) ambivalence. 35,54,57,73 Potential ambivalence, also referred to as objective ambivalence, structural ambivalence or indirect ambivalence, represents a psychological state of coexistence between positive and negative evaluations of an object. It is usually measured using mathematical formulas (most commonly the Griffin Index) 75 that combine unipolar scales (also called split semantic differential scales) meant to separately assess to which extent an individual perceives an object of attitude as positive or negative (expressed either as positive and negative aspects of the object or as adjectives that describe desirable or undesirable characteristics, or approach and avoidance inclinations), emphasising the similarity and the intensity of the two evaluations.…”

“…We chose these items of food because pre-testers evaluated apple slices positively and chips ambivalently (Batista & Lima, 2010). We chose Pringles because these chips are always of the same size.…”

Quem está comendo comigo?: influência social indirecta no comportamento alimentar ambivalente

“…A alimentação revela-se uma boa área para estudar a ambivalência atitudinal na medida em que, frequentemente, os alimentos suscitam um conflito entre o prazer e a saúde (Conner & Armitage, 2002;Conner & Sparks, 2002). A investigação tem vindo a apoiar esta ideia (e.g., Batista & Lima, 2010;Urland & Ito, 2005) e, para além disso, tem demonstrado que a ambivalência na alimentação existe principalmente face a alimentos não saudáveis 1 (Batista & Lima, 2010;Urland & Ito, 2005). * Endereço para correspondência: Instituto Universitário de Lisboa, Av.…”
