A machine learning (ML) approach to understanding participation in government nutrition programs.

Machine Learning (ML) affords researchers tools to advance beyond research methods commonly employed in psychology, business, and public policy studies of federal nutrition programs and participant food decision-making. It is a sub domain of AI that is applied for feature extraction - a crucial step in decision making. These features are used in context-specific automated decisions resulting in predictive AI models.

Psychological reactance impacts ratings of pediatrician vaccine-related communication quality, perceived vaccine safety, and vaccination priority among U.S. parents.

Physician communication surrounding vaccination is important in driving patient compliance with schedules and recommendations, but patient psychological factors suggest that communication strategies may have differential effects on patients. This paper investigates how psychological reactance, defined as an individuals' propensity to restore their autonomy when they perceive that others are trying to impose their will on them, impacts perceptions about physician communication and perceptions and prioritizations of vaccination. We propose and describe the results of a study that was conducted to assess the relationship between individual differences in reactance, perceived quality of pediatrician communication, perceptions of vaccination safety, and vaccination prioritization using a sample of parents.

When variety is not the spice of life: The influence of perceived relational self-threat on variety seeking in snack choices.

People often seek variety in food choices because they believe variety offers them many benefits such as giving them a chance to explore new foods while decreasing the likelihood of boredom from eating the same food repeatedly. While much research has explored situational factors that increase variety seeking behavior, we explore a situational factor that decreases variety seeking. Specifically, this research investigates how perceived relational threat affects variety seeking in snack choices.

Negative associations of frozen compared with fresh vegetables.

Despite convenience and nutrition advantages of frozen vegetables, consumption of them is low compared with fresh vegetables and continues to decrease. In two studies, we observe a negative bias for frozen vegetables compared with fresh vegetables. In study 1, we used an Implicit Association Test (IAT) to demonstrate that generalized negative associations with frozen vegetables are automatic, robust, and ingrained in long-term memory.

When open access might not work: Understanding patient attitudes in appointment scheduling.

Background: Open-access (OA) systems aim to reduce delays to care. However, recent evidence suggests that OA systems might reduce patient satisfaction and result in poorer patient experiences due to patients' inability to obtain appointments with their usual care provider. We conducted a series of experiments to explore the role of risk attitudes, an individual difference variable that measures preferences for risky options, in patients' perception of OA systems.

Helping lower income parents reduce the risk of food waste resulting from children's aversion to healthier food options: Comment on Daniel (2016).

We reflect on Daniel's (2016) finding that a challenge to improving the diets of lower income children is parental worry over food waste that results from children's rejection of healthier food options such as vegetables. This finding has important implications because previous research has indicated novel foods that have a bitter or sour flavor profile (as is the case with many vegetables) must be introduced to children several times before these foods are accepted. We suggest research-based techniques that parents could utilize to reduce the risk of costly food waste, and discuss obstacles that could impede well-intended parents from reaching their goals of improving their children's diets.

Dissociation from beloved unhealthy brands decreases preference for and consumption of vegetables.

Many people form strong bonds with brands, including those for unhealthy foods. Thus, prompting people to dissociate from beloved but unhealthy food brands is an intuitively appealing means to shift consumption away from unhealthy options and toward healthy options. Contrary to this position, we demonstrate that dissociating from unhealthy but beloved brands diminishes people's interest in consuming vegetables because the dissociation depletes self-regulatory resources.

A new model for nurse practitioner utilization in primary care: increased efficiency and implications.

Background: Nurse practitioners (NPs) play an important role in providing quality primary care. However, little is known about organizational processes that best utilize NPs in care delivery and what kind of resources and support NPs need to deliver quality care within their organizations. In primary care settings, NPs often receive little support from ancillary personnel compared with physicians.

Development and psychometric testing of the Nurse Practitioner Primary Care Organizational Climate Questionnaire.

Background: Policy makers and healthcare organizations are calling for expansion of the nurse practitioner (NP) workforce in primary care settings to assure timely access and high-quality care for the American public. However, many barriers, including those at the organizational level, exist that may undermine NP workforce expansion and their optimal utilization in primary care.

Objectives: This study developed a new NP-specific survey instrument, Nurse Practitioner Primary Care Organizational Climate Questionnaire (NP-PCOCQ), to measure organizational climate in primary care settings and conducted its psychometric testing.

Appointment reminder systems and patient preferences: Patient technology usage and familiarity with other service providers as predictive variables.

This study had two aims: to measure patient preferences for medical appointment reminder systems and to assess the predictive value of patient usage and familiarity with other service providers contacting them on responsiveness to appointment reminder systems. We used a cross-sectional design wherein patients' at an urban, primary-care clinic ranked various reminder systems and indicated their usage of technology and familiarity with other service providers contacting them over text messages and e-mails. We assessed the impact of patient usage of text messages and e-mails and patient familiarity with other service providers contacting them over text messages and e-mails on effectiveness of and responsiveness to appointment reminder systems.

Recommendations implicit in policy defaults.

Should people be considered organ donors after their death unless they request not to be, or should they not be considered donors unless they request to be? Because people tend to stay with the default in a variety of domains, policymakers' choice of default has large and often important effects. In the United States, where the organ-donation policy default is "not a donor," about 5,000 people die every year because there are too few donors. Four experiments examined two domains-being an organ donor and saving for retirement-where default effects occur and have important implications.
