Abstract Background The diet of young adults is poor, yet little is known about the relative importance of influences on healthy eating in a decision-making context. The aim of this exploratory study was to understand the relative ranking of influences on meal choices in young adults and to investigate interactions between meal preferences and demographic and health characteristics. Methods Adults aged 18–30 years (n = 92, mean age: 23.9 (SD 3.4) years) completed an online discrete choice experiment. Participants were presented with 12 choice sets reflecting a typical weekday meal and were asked to choose between four meal options. Each meal consisted of a combination of five meal attributes (preparation time, cost, taste, familiarity and nutrition content) that each had three attribute levels. Data were analysed using conditional logit models. Subgroup analyses were performed by sex, education, income, weight status and meeting fruit and vegetable recommendations. Results Comparing the highest and lowest attribute levels, meal preferences were higher for better taste (B = 0.38; 95% CI: 0.12, 0.63), familiarity (B = 0.37; 95% CI: 0.21, 0.54) and nutrition content (B = 1.11; 95% CI: 0.81, 1.41) and lower for increased preparation times (B = −0.33; 95% CI: − 0.53, − 0.12) and cost (B = −0.50; 95% CI: − 0.75, − 0.24). Nutrition content was the most important influence on meal choice. Cost was the second most important, followed by taste, familiarity and preparation time. Compared to males, females had a higher preference for better nutrition content, taste and familiarity and a lower preference for increased cost. Higher educated participants had a higher preference for better nutrition content, familiarity and taste compared to lower educated participants. Young adults who met recommendations for fruit and vegetable intake had a higher preference for better nutrition content compared to participants who did not meet recommendations. Conclusion Nutrition content was the most important influence on young adults’ meal choices, followed by cost, taste, familiarity and preparation time. Preferences varied by demographics and health characteristics, suggesting that the focus of dietary interventions may benefit from being tailored to specific young adult groups.

Cigarette Package

BackgroundThe US Food and Drug Administration (FDA) has regulatory authority to use inserts to communicate with consumers about harmful and potentially harmful constituents (HPHCs) in tobacco products; however, little is known about the most effective manner for presenting HPHC information.MethodsIn a discrete choice experiment, participants evaluated eight choice sets, each of which showed two cigarette packages from four different brands and tar levels (high vs low), accompanied by an insert that included between-subject manipulations (ie, listing of HPHCs vs grouping by disease outcome and numeric values ascribed to HPHCs vs no numbers) and within-subject manipulations (ie, 1 of 4 warning topics; statement linking an HPHC with disease vs statement with no HPHC link). For each choice set, participants were asked: (1) which package is more harmful and (2) which motivates them to not smoke; each with a ’no difference' option. Alternative-specific logit models regressed choice on attribute levels.Results1212 participants were recruited from an online consumer panel (725 18–29-year-old smokers and susceptible non-smokers and 487 30–64-year-old smokers). Participants were more likely to endorse high-tar products as more harmful than low-tar products, with a greater effect when numeric HPHC information was present. Compared with a simple warning statement, the statement linking HPHCs with disease encouraged quit motivation.ConclusionsNumeric HPHC information on inserts appears to produce misunderstandings that some cigarettes are less harmful than others. Furthermore, brief narratives that link HPHCs to smoking-related disease may promote cessation versus communications that do not explicitly link HPHCs to disease.

Abstract   Active surveillance after neoadjuvant chemoradiotherapy for locally advanced resectable esophageal cancer is currently topic of investigation. In a discrete choice experiment, patients’ preferences can be quantified by asking patients to state their preference over hypothetical treatment alternatives. The aim of the present study was to assess patients’ preferences for either active surveillance or standard esophagectomy in patients who underwent neoadjuvant chemoradiotherapy followed by surgery without signs of recurrence. Methods A discrete choice experiment was performed in esophageal cancer patients who underwent neoadjuvant chemoradiotherapy followed by standard esophagectomy at least one year earlier. Patients completed a questionnaire consisting of eighteen choice sets considering active surveillance or standard esophagectomy. Treatment alternatives were characterized by attributes with varying attribute levels hypothesized to influence treatment choice: five-year survival, short-term and long-term health related quality of life (HRQOL), annual number of diagnostics required and the risk that esophagectomy is still necessary later in time. The importance of attributes and willingness to trade-off 5-year survival for other attributes were assessed using panel latent class model. Results A total of 107 patients were consecutively included, of whom 100 (93%) responded between August 2018 and October 2020. Regardless of the attribute levels, 28 patients preferred active surveillance and 28 patients preferred standard esophagectomy. When considering both treatments, five-year survival and long-term HRQOL were considered most important attributes. Patients were willing to trade-off 5.4% five-year overall survival to obtain a better long-term HRQOL. Conclusion At least one year after neoadjuvant chemoradiotherapy and esophagectomy, over a quarter of patients would choose not to undergo standard esophagectomy again, regardless of the attribute levels. Patients were willing to trade-off five-year survival chance in order to achieve an HRQOL which was much better than their own situation. When considering both treatments, five-year survival and long-term HRQOL were the most important determinants in the choice for treatment.

AbstractThis chapter covers various issues related to the experimental design, a statistical technique at the core of a discrete choice experiment. Specifically, it focuses on the dimensionality of a choice experiment and the statistical techniques used to allocate attribute levels to choice tasks. Among others, the pros and cons of orthogonal designs, optimal orthogonal in the differences designs as well as efficient designs are addressed. The last section shows how a simulation exercise can help to test the appropriateness of the experimental design.

Abstract Purposes: The purposes of this discrete choice experiment are as follows:1.To investigate the preference of gastric cancer survivors for follow-up care.2.To quantify the importance of follow-up care-related characteristics that may affect the gastric cancer survivors’ choices of their follow-up, so as to provide references for development of the follow-up strategy of gastric cancer survivors.Methods: Discrete choice experimental design principles was applied to develop the survey instrument. All questionnaires were filled out by the respondents and collected on site. A mixed logit model was used to estimate gastric cancer survivors’ preferences. Willingness to pay estimates and simulations of follow-up uptake rates were calculated.Results: All six attributes are significant important for the follow-up care of gastric cancer survivors (p＜0.05). Achieving very thorough follow-up contents was the most valued attribute level (coefficient=1.995). Specialist doctors are the most preferred providers, followed by specialist nurses and gastric cancer survivors were willing to pay more for these attribute levels. Changes in attribute levels affected uptake rate of follow-up. When the multiple attribute levels were changed at the same time, a very thorough follow-up contents provided by the same specialist doctor (specialist nurse), the probability of receiving follow-up increases by 95.82% (94.90%).Conclusions: The characteristics of follow-up care in our study reflect the health management services expectations of gastric cancer survivors. A dedicated specialist nurse involved in follow-up care should be developed to contributes to solve the complex and multifaceted personal needs of gastric cancer survivors.
