This research is a continuation of a usability study with the MARVIN chatbot. The investigators aim to adapt the MARVIN chatbot to open it to other health domains (e.g. breast cancer) and populations (e.g. pharmacists). Therefore, this protocol constitutes a master research protocol that will englobe different research projects with individual chatbots. The investigators adopt an adaptive platform trial design, which will allow flexibility in handling multiple interventions adapted to different populations while retaining the characteristics of a platform trial design allowing early withdrawal of ineffective trial arms based on interim data (implementation outcomes) and introduction of new trial arms.

Usability Metric for User eXperience (UMUX-Lite)
The UMUX-Lite is a 2-item questionnaire, answered on a 7-point Likert scale (1 = strongly disagree to 5 = strongly agree), that was deemed appropriate for evaluating medical technology. The items ask whether the chatbot meets the user's needs and the user's perceived ease of use. Scores range from 0 to 100, with more than 68 being considered high usability according to the literature.
Acceptability E-Scale (AES)
The AES contains 6 items rated with different 5-point Likert scales (e.g., 1=very difficult to 5=very easy). It is a validated measure of acceptability and usability of computer-based interventions for health populations. Scores range from 0 to 30, and according to the literature, scores above 24 are considered high acceptability.

Change in Intervention Appropriateness Measure (IAM) over 12 months
Appropriateness relates to the relevance or compatibility of the innovation to address a particular issue or problem. The compatibility of an information technology innovation is the extent of which it is considered consistent with users' values, needs, and past experiences. The Compatibility Subscale is a validated tool that contains three items and evaluates on 7-points Likert scales (1 = extremely disagree to 7 = extremely agree) how an IT innovation "fits" with the user's work style. A modified version could be used by healthcare professionals, such as pharmacists.
