Designing to elicit future affective potential
Changing the default meal option at university events to reduce harmful environmental impacts
Animal agriculture is a leading contributor to greenhouse gas emissions and other harmful environmental impacts, which underscores the need to shift away from the consumption of animal-based products. One promising nudge intervention is making plant-based meals the default option, so we tested this approach at six different university events across four academic institutions for effecting sustainable dietary change. Event attendees pre-selected t…
Food Appreciation Scale Development and Dimensionality Assessment
Food appreciation has been associated with favorable dietary and food waste behaviors. However, no validated food appreciation assessment currently exists. This study aimed to develop and validate a food appreciation scale (FAS) using data from two independent US-based samples recruited online. The 29-item FAS was based on existing literature regarding appreciation as a psychological construct, mindful eating, and epicurean tendencies. In Study 1…
Covid-19-Related Changes in Perceived Household Food Waste in the United States
Food waste contributes to adverse environmental and economic outcomes, and substantial food waste occurs at the household level in the US. This study explored perceived household food waste changes during the COVID-19 pandemic and related factors. A total of 946 survey responses from primary household food purchasers were analyzed. Demographic, COVID-19-related household change, and household food waste data were collected in October 2020. Wilcox…
A goal-systems perspective on plant-based eating
Objective: To explore adherence to a plant-based diet from the perspective of goals- and motivations-based systems. Design: A cross-sectional, survey-based study was conducted regarding eating patterns, goals and motivations for current eating habits. Setting: Data were collected using an online survey platform, including the Goal Systems Assessment Battery (GSAB) and other survey tools. Participants: University students were recruited, including…
No Significant Differences in Muscle Growth and Strength Development When Consuming Soy and Whey Protein Supplements Matched for Leucine Following a 12 Week Resistance Training Program in Men and Wome…
There are conflicting reports regarding the efficacy of plant versus animal-derived protein to support muscle and strength development with resistance training. The purpose of this study was to determine whether soy and whey protein supplements matched for leucine would comparably support strength increases and muscle growth following 12 weeks of resistance training. Sixty-one untrained young men ( n = 19) and women ( n = 42) (18-35 year) enrolle…
From TVs to tablets
The present study found that poorer dietary choices, as well as other negative health-related impacts, occurred more often as the viewing time of a variety of different screen-based devices increased in a sample of US adults. Future research is needed to better understand what factors among different screen-based devices might affect health behaviors and in turn health-related outcomes. Research is also required to better understand how binge-wat…
Reliability of a new measure to assess modern screen time in adults
Results from this study suggest this self-administered questionnaire may be used to successfully classify individuals into different categories of screen time use (e.g. high vs. low); however, it is likely that objective measures are needed to increase precision of screen time assessment
Identifying attributes of food system sustainability
A qualitative study of shopper experiences at an urban farmers’ market using the Stanford Healthy Neighborhood Discovery Tool
Objective To understand factors which enhance or detract from farmers’ market shopper experiences to inform targeted interventions to increase farmers’ market utilization, community-building and social marketing strategies. Design A consumer-intercept study using the Stanford Healthy Neighborhood Discovery Tool to capture real-time perceptions via photographs and audio narratives. Setting An urban farmers’ market in a large metropolitan US city. …
Community Supported Agriculture Programs
Local foods programs such as community supported agriculture programs (CSAs) and farmers' markets have increased greatly in popularity. However, little research has been conducted regarding the effect of involvement in local foods programs on diet-related attitudes and behaviors. A series of focus groups was conducted to identify the motives that propel individuals to join a CSA, the experiences of belonging to a CSA, and the diet-related outcome…
Community supported agriculture membership in Arizona. An exploratory study of food and sustainability behaviours
Implementation of Wireless Terminals at Farmers’ Markets
Although farmers’ markets offer healthy foods for purchase, many lack the equipment necessary to process convenient, card-based transactions. We assessed the impact of providing wireless terminals to 5 markets on overall sales and redemption of Supplemental Nutrition Assistance Program (SNAP) benefits. Sales increased significantly at 4 of the 5 markets after implementation of the terminals, and overall sales increased above and beyond SNAP redem…
Bertmann et al. Respond
It is gratifying to read that the author of the letter observed improvements to overall sales and electronic benefit transfer (EBT) redemption during similar work conducted at Penn State College of Medicine in 2010. In subsequent interactions at our farmers’ markets, we also observed a comparable trend in vendors conducting point-of-sale transactions through smart phones and tablet devices. A study under way in our group at Arizona State Universi…
