Notwithstanding their potential benefits especially for individuals with low health literacy, users are still somewhat skeptical about the reliability of healthcare chatbots. The present study aims to address this challenge by investigating strategies to enhance users’ cognitive and emotional trust in healthcare chatbots. Particularly, this study aims to understand the effects of chatbot design cues in increasing trust and future chatbot use intention for low health literacy users.

We conducted two experimental studies with a final sample of 327 (Study 1) and 241 (Study 2). Three different chatbots were developed (Chatbot design: Bot vs Male-doctor vs Female-doctor). Participants were asked to have a medical consultation with the chatbot. Participants self-reported their health literacy scores. The PROCESS model 7 was used to analyze the hypotheses.

The results showed that the female-doctor cues elicited greater cognitive and emotional trust, whereas the male-doctor cues only led to greater cognitive trust (vs bot-like cues). Importantly, this study found that users’ health literacy is a significant moderating factor in shaping cognitive and emotional trust. The results indicated that both the female and male-doctor cues’ positive effects on cognitive trust were significant for those with lower levels of health literacy. Furthermore, the positive effect of the female-doctor cues on emotional trust was also significant only for those whose health literacy level was low. The increased cognitive and emotional trust led to greater future intention to use the chatbot, confirming significant moderated mediation effects.

Despite the strong economic and educational benefits of healthcare chatbots for low health literacy users, studies examining how healthcare chatbot design cues affect low health literate users surprisingly remained scarce. The results of this study suggest that healthcare chatbots can be a promising technological intervention to narrow the health literacy gap when aligned with appropriate design cues.

The aim of the study is to capture consumers' conceptualization of ethnic food and ethnic restaurants, focusing on what it takes for ethnic restaurants to be perceived authentic.

Qualitative research, based on semi-structured in-depth interviews which were transcribed and subjected to inductive thematic analysis.

The findings conceptualize what ethnic food and ethnic-authentic restaurant are, leading to formulating the criteria that authentic ethnic restaurant should meet.

Findings have practical implications for restaurateurs interested in establishing themselves as ethnically authentic and for businesses focusing on ethnic food. This study was based on Israeli-Jewish participants; studies with other populations will contribute to the findings' trustability.

This study provides novel and critical insights into ethnic restaurant managements and to the customer conceptualization of the concept of ethnic authentic, demonstrating it being a multifaceted concept.
