For this study, we have created five different conversational agents with differing personalities using the Big Five personality traits and their low and high varying extroversion and conscientiousness. In addition, we have an agent with a neutral personality type. Our main goal of the study is to find out how you perceive these agents and their personalities, and whether your personality has an impact on this.

Each agent follows a similar conversational track and the main difference between these agents is how they express the message. In the conversations, the agents suggest self-help methods for mild mental health conditions and provide you with additional sources for mental health self-help. Please note, that the agents are not intended for professional healthcare use. If you suffer from a mental health condition and would like help, please contact your doctor. If talking to any of the agents makes you feel uncomfortable, please remember that you can terminate your participation at any time.

After each conversation with an agent, you are asked to fill a short UES-SF (User Engagement Scale) that we use to measure your opinion on the agent. This is repeated five times, once for each different agent.

After you have successfully finished the conversation with each of the agents, you are asked to fill a final survey in which you are also asked to fill a short 10-item personality questionnaire (TIPI) which we use to see whether your personality has an impact on your opinion on different agent personalities.


In this study, you will have a short mental health-related conversation with five different conversational agents (chatbots) with differing personalities. After each conversation, you are asked to fill a short survey of your feelings towards the agent you were talking to and after finishing conversations with all five agents, you are also asked to fill a short personality questionnaire. The conversations you have with these agents will not be recorded. Please be assured that your responses will be kept entirely confidential and individual participants will not be recognizable based on their answers. The information that you provide will be used for the purposes of academic research.

Your participation in this research is voluntary. You have the right to withdraw at any point during the study, for any reason, and without any prejudice. If you wish to terminate your participation, please cancel your participation on Prolific. You are also asked for consent later on in the study, but please bear in mind, that you can still decide to terminate your participation in the study both before and after this.

By giving consent, you acknowledge that your participation in the study is voluntary, you are at least 18 years of age, and that you are aware that you may choose to terminate your participation in the study at any time and for any reason.
