“…The result of our study is in line with the findings of Mazloomy Mahmoodabad et al . that reported Intention to non-consumption of fast foods had a positive significant correlation with subjective norms, attitude, willingness, and prototype of fast food consumption 22 That shows more positive attitude and subjective norms of fast-food consumption is accompanied by more intention of consuming fast foods and showing more of the behavior.…”

BACKGROUND: Today, marked by advanced scientific approach, urbanism, and changing life style, there is an ever-growing rate of fast-food consumption, which has significantly affected public health. Hence, the present research aimed to predict factors involved in fast-food consumption in light of the prototype/willingness model among the students of Rafsanjan University of Medical Sciences. MATERIALS AND METHODS: In the present descriptive/analytical research conducted in 2018–2019, 350 students in Rafsanjan University of Medical Sciences were selected through proportionate stratified random sampling. The required data were collected using a self-administrated questionnaire in light of the constructs within the prototype/willingness model and fast-food consumption behavior. The data were analyzed in SPSS version 16.0 using descriptive and inferential statistics including mean scores, standard deviation, correlation coefficient, and linear regression. RESULTS: Behavioral intention of fast-food consumption showed to be positively correlated with positive willingness, positive prototype, positive subjective norms, and positive attitude toward fast-food consumption. Furthermore, the correlation between positive behavioral intention of consuming fast food and positive subjective norms and positive attitude toward fast-food consumption was statistically significant ( P < 0.05). The underlying constructs of prototype/willingness model altogether managed to explain 13% of the total variance of fast-food consumption behavior. Behavioral intention showed to be the strongest predictor of the behavior (β = 1.613). CONCLUSION: It is suggested that the preventive measures aimed to reduce fast-food consumption among the youth focus more on strengthening negative attitudes and subjective norms concerning fast-food consumption.

“…Diet changes are interventions which entail conscious and subconscious expectations and beliefs ( 56 – 58 ). Generally, we can motivate ourselves to changes especially if we expect an improvement of the existing situation, as illustrated by models such as the Health Belief Modell ( 59 ), the Transtheoretical Model ( 60 ), the Prototype/Willingness Model ( 61 , 62 ), and the Health Action Process Approach ( 63 ). As a rule, individuals change their diet because they have expectations, e.g., health-promoting, weight-reducing effect, and/or appreciation from the social environment.…”

Placebo (PE) and nocebo effects (NE) have been subjects of systematic research in medicine and psychotherapy for many decades to distinguish between the (specific) pharmacological effect of medication and the (unspecific) effect of the context. Despite this significant research, the awareness, operationalisation, and reflection of the multiplicity of PE, NE, and psychosocial context effects (PSCE) is currently limited when researching outcomes of diet changes in studies without randomisation and placebo control. This neglection is critical as it could systematically influence outcomes by moderating and mediating them and thus reducing the validity and evidence base of these studies. Therefore, we performed a (non-systematic) narrative review (NR) on the following objectives: (1) present a concise overview about the relevance of PE, NE, and PSCE in medicine and nutrition research; (2) review the current state of research on reflecting context effects when studying diet changes; (3) provide useful theoretical foundations via consideration and integration of micro- and macro context effects; (4) operationalise as hypotheses the potential PE, NE, and PSCE which are specific for researching diet changes; and (5) derive their impact for future research as well as for nutrition counselling. The electronic search in this NR for objective (2) identified N = 5 publications and for objective (4) we found N = 61 articles retrieved in the first round of search, additional references were identified by a manual and snowball search among the cited references resulting finally in N = 37. This NR offers a synoptical basis to foster awareness and operationalisation of a variety of PE, NE, and PSCE. Interdisciplinary research teams should monitor these factors using, e.g., qualitative, mixed-method studies, process evaluation, item bank approaches, moderator and mediator analysis that might reveal substantially new insights, and outcomes of relevance to science and nutrition counselling. Nevertheless, the present NR has several limitations, especially as it is non-systematic, because it is a very heterogeneous field of research, in which the topic we are investigating is usually regarded as marginal and subordinate. Therefore, future research should conduct systematic reviews and particularly theory-based primary studies (experimental research) on hypotheses of PE, NE, and PSCE in outcome research in diet changes.
